(57) Abstract:

Heater for use in a Smoking article with a source of electricity to heat tobacco flavored environment contains a substrate of electrically conductive material, made with the possibility of electrical connection to an electrical power source, and an electric insulator deposited on at least part of the substrate, and an electric resistive heating element. The first end of the heating element connected to the substrate. The second end of the heating element and the portion of the heating element between the first and second ends are isolated from the substrate. Resistive heating circuit is formed with the possibility of heating the heating element to heat tobacco flavored environment. The design of this heater, and a heater for use in a Smoking article with a source of electricity for heating cylindrical cigarette and a method of manufacturing a heater for use in an electrical Smoking article provide for the creation of conditions of the area, for which there is no vapour, which positively affects the performance of electrical contacts and associated with them, who pines for use in electrical products for Smoking, and, more particularly, to tubular heater for use in an electric product for the area.

Previously known conventional Smoking devices transmit the user aroma and a pleasant smell in the combustion of tobacco. The mass of combustible material, mainly tobacco, is oxidized in the application of heat with the usual temperatures of combustion in a conventional cigarette that exceed 800oC during tightening. Heat runs through the surrounding mass of tobacco by attraction to the end in his mouth. During this heating is efficient oxidation of combustible material, which gives the various products of the distillation and thermal decomposition. When these products pass through the body of the Smoking device to the mouth of the user, they are cooled and condensed, forming an aerosol or vapor that gives the consumer the flavor and pleasant aroma associated with Smoking.

Conventional cigarettes have associated with them various perceived by the user disadvantages. These include the formation of side stream smoke in combustion between puffs, which may be unpleasant for some change. In addition, after ignition, they must at one time fully to use(aroma, the taste, smell) this is an unattractive prospect for sophisticated smokers.

Known alternatives to conventional cigarettes include cigarettes, which itself combustible material does not directly provide the aromatic properties of inhaled by the smoker sprays. In these Smoking products fuel heating element, usually carbon, by nature, is burned to heat the air as it moves through the heating element and through the zone, which contains heat-activated items, liberating flavored spray. Although this type of Smoking device creates little or no side creates a stream of smoke, he still produces combustion products, and after ignition it is not suitable for breathing in case of another future use in the ordinary sense.

During use as a conventional device and the device area with the carbon heating element is above the burning. This process, of course, gives rise to large quantities of by-products when burned material is destroyed and communicates with the surrounding atmosphere.

In U.S. patent N 5093894, 5225489, 5060671 and 5095921 disclosed to the public reduce the side stream smoke, allowing the smoker the option to pause and re-start Smoking. However, as described in these patents products cigarettes are not very durable and can break, crack, or break down from prolonged or rough handling. In some circumstances, these known products cigarettes can be crushed when inserting them into electrical lighter. After their disposable Smoking, they are even more fragile and can break and tear during removal of the lighter.

From international patent application WO 94/06313 known heater for use in a Smoking article with a source of electricity to heat tobacco flavored medium containing a substrate of electrically conductive material, made with the possibility of electrical connection to an electrical power source.

From the same publication known heater for use in a Smoking article with a source of electricity for heating cylindrical cigarette containing a cylindrical tube of electrically conductive material provided with many through her gap, forming a set of electrically conductive blades defining a receiver for receiving ostavlennogo products this blade is directed from the end of the sleeve, which is made with the possibility of being in electric contact with the source of electricity.

In addition, this publication disclosed a method of manufacturing a heater for use in an electrical Smoking article, intended for heating of cylindrical cigarettes, which provide electrically conductive material, forming a set of blades from an electrically conductive material having between them a gap, and a common end part, and blades extending from a common end portion, form a set of blades and a common end portion in the cylindrical receiver for receiving the inserted cigarette.

The electrical system for the area that is disclosed in the international patent application WO 94/06314 includes lighter with power supply and a cigarette, which is adapted for use with a cigarette lighter. The preferred option lighters includes many metal sinusoidal heaters arranged in a configuration that allows a sliding way to insert the rod-like tobacco part of the cigarette.

As described in the application WO 94/06314 preferred, wrapped around the tubular holder, the device filter inserts end-to-end flow for such holder and filter basket on the opposite (remote) end of the holder, which is preferably restricts the air flow in the axial direction through the cigarette. A cigarette and a lighter perform in such a way that when a cigarette is inserted into the lighter and when the individual heaters are driven for each torque, is localized charring at points around the cigarette in locations, where each heater comes to cigarettes. After actuation of all heaters, these charred points are close to each other and surround the middle part of the plot holder cigarette. Depending on the maximum temperature and the total energy supplied to the heaters, charred point find not only a simple color change of cigarette paper. In most applications, the charring creates at least small tears in cigarette paper and below the material of the holder, where each gap tends to mechanically weaken the cigarette. When withdrawing a cigarette from the lighter, charred point should at least partially slide on nagrevatelem may be prone to breaking or leaving pieces when it is drawn out of the lighters. The pieces remaining in the mounting bracket lighters, can interfere with the correct operation of lighters and/or modify the taste of the next cigarette. If cigarette will break into two pieces when dragging, the smoker may face not only a disappointment in respect of the damage cigarette products, but also with prospective cleaning debris from clogged lighters before he or she will be able to use another cigarette.

As described in the application WO 94/06314 preferred cigarette is an essentially hollow tube between the filter elements, such as the cigarette end and inserting at the remote end. I believe that this design promotes the flow of aerosols to the smoker by providing sufficient space, in which the aerosol may be released from the holder with a minimum appearance and condensation aerosols on any nearby surfaces.

Put forward several proposals, which essentially reduce unwanted side exit of the smoke, allowing the smoker to stop Smoking products within the required time period, and then resume Smoking. In the application WO 94/06314 disclosed electrical Smoking article having the heaters is teli are preferably relatively thin serpentine design, designed for the transfer of sufficient amounts of heat to the cigarette and having a light weight.

Although the above described devices and heaters overcome the observed problems and reach goals, many options for their implementation suffer from the formation of significant amounts of condensation in the heat tobacco flavored environment to form a vapor. These pairs can create problems when they condense on the relatively colder various electrical contacts and associated control and logic circuits. In addition, condensation may interfere to influence the perceived flavor of the tobacco environment cigarette. Although there is no theoretical explanation, suppose that the condensation is the result in the form of flow and the pressure gradient of the ambient air being drawn through the product, and the modern sights of the heating units. Heating the tobacco odorous environment releases pairs, which are then cooled, allowing condensation to form on the surfaces of relatively colder elements. Condensation can cause short circuits and other unwanted problems.

In addition, the proposed heaters are subjected to mechanical weakening and the and, as well as regulation or neglect when the inserted cigarette.

Further, in electrical products for Smoking using electric resistance heaters, have required relatively complicated electrical connections, which can interfere with the insertion and withdrawal of cigarettes.

It may include devices such as a capacitor or, more preferably, rechargeable battery. In the preferred in the present embodiment, the power source is replaceable, rechargeable battery, for example, four series-connected element cadmium-Nickel batteries with a total voltage without load is approximately equal to 4.8 and 5.6 volts. However, the characteristics required of the power source 37 is chosen in view of the characteristics of other elements in the Smoking system 21, in particular the characteristics of the heating elements. In U.S. patent N 5144962 described several forms of energy sources used in cooperation with the present invention a tobacco system, for example, sources such as rechargeable batteries and power sources type rapidly discharge capacitor, the charger, side buttons is estu cylindrical heating clamping device 39, designed to heat the cigarette 23 and, preferably, to hold the cigarettes in place relative to the lighter 25, and an electric control circuit 41, designed to supply a predetermined amount of power from the power source 37 to the heating elements (not shown in Fig. 1 and 2) of the valve. As described in more detail below, in Fig. 3 shows that generally round terminal bushing 110 is attached, for example welded, thus, to be located in the inner part of the heating valve 39, for example, attached to a spacer sleeve 49. If the heater has two end sleeves, each sleeve can function as a fixed terminal end. In the preferred in the present embodiment, the heating fixture 39 includes multiple distributed in the radial direction of the heating elements 122 supported so that they walked away from the sleeve, as shown in Fig. 3 and described in more detail below, and separately powered from a source 37 under the control circuits 41 to heat range, for example, eight areas around the periphery of the inserted cigarette 23. To get eight puffs preferred the comrade made with the possibility of electric control consisting of two parts of the device. It is possible to generate the desired number of puffs, for example, any number between 5 and 16, and preferably between 6 and 10 or 8 on an inserted cigarette. As described below, the number of heaters may exceed the required number of puffs per cigarette.

The electrical circuit 41 preferably is actuated is shown in Fig. 1, which is driven by the puff sensor 45, which is also sensitive to pressure drops that occur when a smoker smokes a cigarette 23. Driven by tightening the sensor 45 is preferably located in the front part 33 of the lighter 25 and communicates with the inner space of the heating fixture 39 and near the cigarette 23 through the passage, passing through the spacer and the base valve of the heater and, if required, a tube (not shown) of the sensor tightening. Driven by puff sensor 45, suitable for use in the Smoking system 21 is described in U.S. patent 5.060.671, and has a shape model of a silicon sensor RD produced by the Department of Microswich" (Microswitch firm "Hanival Inc. (Honeywtll, Inc. ) , Freeport, Illinois. This sensor activates the corresponding one of the heating elements 122 as a result of changes plooy anemometry, can be used successfully to actuate the corresponding one of the heating elements 122 when it detects changes in the air flow.

The indicator 51 preferably includes a seven-segment liquid crystal display. In the preferred in the present embodiment, the indicator 51 displays the digit "8" for use with a cigarette in eight puffs, when a beam of light emitted is shown in Fig. 1 light sensor 53, is reflected from the front of the newly inserted cigarette 23 and detected by a light sensor. The light sensor 53 is preferably mounted in the opening in the spacer sleeve and the base of the clamping device 39 of the heater. The light sensor 53 provides a signal to the circuit 41, which, in turn, provides a signal to the indicator 51. For example, displaying the numeral "8" on the indicator 51 reflects that the preferred eight puffs provided in each cigarette 23, available, i.e., none of the heating elements 43 is not operated AI cigarette 23 in the lighter 25, the light sensor 53 does not detect the presence of cigarette 23 and the indicator 51 is turned off. The light sensor 53 is modulated in such a way that it does not constantly emits a beam of light and does not provide unnecessary discharging of the power source 37. Preferred at the present time, the light sensor 53, suitable for use with the Smoking system 21 is a light sensor type OPR 5005, manufactured by the firm "optics technology, Inc. (OPTEX Technology, Inc.), 1215 West Crosby road, Carrolton, Texas 75006, USA.

As one of several possible alternatives for use of the above-mentioned light source 53, it is possible to provide a mechanical switch (not shown) for detecting the presence or absence of a cigarette 23 and it is possible to ensure the return button to its original state (not shown) intended for recovery circuit 41, when the lighter 25 inserts a new cigarette, for example, in order to make the indicator 51 to display the digit "8" and so on, the power supply of the electric circuit, which is driven by the air flow sensor and indicator used in the corresponding present invention Smoking system 21, described in U.S. patent N 5.060.671 and application neprorezaemye during Smoking.

Will now be more fully described and shown the preferred at the present time, the cigarette 23, intended for use with the Smoking system 21 described in the above-mentioned patent application WO 94/06314, although the cigarette may be of any desired shape, capable of generating a reciprocal feeling of flavored tobacco for transmission to the smoker when the cigarette is heated heating element 122. Considering Fig. 2, note that the cigarette 23 includes tobacco film 57 formed from the holder or filled with substance space 59 which supports the tobacco flavorful material 61 preferably includes tobacco. Tobacco film 57 is wrapped around a cylindrical filter backwash 63 at one end and a cylindrical first filter, free flow 65 at the opposite end, and this film is supported by them. The first filter free flow 65 is preferably a filter of the type "open tube", having a longitudinal channel 67, passing through the middle part of the first filter free passage and, therefore, provides a low resistance for drawing air or free flow.

If necessary, around the tobacco dps which include paper with low weight basis, preferably the paper with the tobacco flavored coating or paper on tobacco basis for strengthening tobacco odor response sensations flavored tobacco. Wrapping paper 69 can be coated with a concentrated solution of the extract complete or diluted fortress. Wrapping paper 69 preferably has a minimum weight and caliber bases, while providing sufficient tensile strength in case of mechanical treatments. Preferred in the present paper specifications on tobacco basis include basis weight (at 60% relative humidity) between 20 and 25 g/m2minimum permeability 0-25CORESTA (defined as the amount of air measured in cubic centimeters, which passes through one square centimeter of material, for example, of a sheet of paper in one minute at a pressure drop of 1.0 to kilopascal), the tensile strength of 2000 g/27 mm width /1 inch / minute (2.54 cm / min)/, the caliber of 1.3-1.5 mils (3,310-2-3,810-2mm), the content of CaCO350, salt, citric acid 0%. Materials intended for use in education wrapping paper 69, preferably include 75% of leaf tobacco basis (filler mixture is not a cigar, smoke-drying and smoke su the teachings of sufficient tensile strength. Wrapping paper 69 may be plain paper from flax fiber with a weight basis of 15-20 g/m2or a coated paper of the extract. You can add a binder in the form of citrus pectin in quantities less than or equal to 1%. You can add glycerin in amounts not greater than necessary to obtain the stiffness of paper, similar to the rigidity of conventional cigarette paper.

Cigarette 23 preferably includes a double filter 71, which is a normal filter RTD-type (resistance to draw), and a cylindrical second filter free flow 73. Double filter and the second filter free flow attached to each other covering paper 75. Covering paper 75 passes by the end of the second filter free flow 73 and is attached to the wrapping paper 69 to secure the end of the first filter free flow 65 at a location near the end of the second filter free flow 73. Like the first filter free flow 65 of the second filter free flow 73 is preferably formed with a longitudinal channel 77, passing through the middle. Filter backwash 63 and the first filter free flow 65 is formed together with the beauty of the La 77 of the second filter free flow 73 was larger than the inner diameter of the longitudinal channel 67 of the first filter free flow 65. Preferred at the present time, the inner diameter for the longitudinal channel 67 are 1 to 4 mm, and a longitudinal channel 77 is 2-6 mm. Noticed that the different internal diameters of the channels 67 and 77 facilitate the formation of the desired mixing or turbulence aerosols produced from the heated tobacco flavorful material and air drawn from the outside of the cigarette 23 during Smoking of the cigarette, providing an improved response to the feeling of flavored tobacco and reducing the impact of the larger end of the double filter 71 to the mixed aerosol. Preferably, the response is a feeling of flavored tobacco that is created by heating the tobacco flavorful material 61, was mainly in vaporous form 9 cavity 79 and converted into a visible aerosol mixing in the channel 77. In addition to the above-described first filter free flow 65 having a longitudinal channel 67, other devices capable of producing the desired mixing reciprocal feelings of flavored tobacco in the vapor phase with the input air, include devices in which the first filter free flow executed in the form of a filter having a lot of little overovanim it full of holes.

The air is preferably drawn into the cigarette 23 is mainly through tobacco film 57 and wrapping paper 69 in the transverse or radial path and not through the filter backwash 63 along the longitudinal path. It is desirable to ensure that the air passes through the filter backwash 63 during the first puff of a cigarette in order to reduce the resistance to retraction (R TD). Now suppose that the drawing of air into the cigarette 23 in the longitudinal direction tends to lead to the creation of aerosols by heating tobacco film heating elements 122 arranged in the radial direction around the tobacco film, not properly removed on the cavity 79. At the present time is preferable to create a reciprocal feeling of aromatic tobacco based almost entirely on the composition of tobacco film 57 and the level of power of the heating elements 122. In accordance with this part of the flow of air through the cigarette, derived from longitudinal flow through the filter backwash 63, preferably a minimum during the area, with the exception of the first tightening. Further, the filter backwash 63 preferably minimizes the flow of aerosols in education the I elements of the lighter 25 back-flow of the aerosol from the cigarette 23 is minimized.

The preferred holders 59 include holders made of cloth woven carbon fiber, which is desirable because of their thermal stability. Such holders described in more detail in patent application WO 94/06314 and the patent application U.S. serial number 07/943.747, filed September 11, 1992

Other holders 59 include a metal screen with a small weight and the open holes or a perforated metal foil. For example, using a screen having a weight in the range from about 5 g/m2to about 15 g/m2and wire diameters from approximately of 0.038 mm (1.5 mils) to about 0.076 mm (approximately a 3.0 mils). Another variant of the screen is formed of foil (e.g. aluminium, of a thickness 0,0064 mm (about 0.25 mils) having perforations with a diameter in the range from about 0.3 mm to about 0.5 mm, to reduce the weight of the foil by about 30-50 percent, respectively. The location of perfo the nternet line) to reduce lateral heat output from tobacco flavorful material 61. Such metal screens and the foil is introduced into a cigarette 23 in a variety of ways, including, for example, 1) pouring tobacco flavored liquid solution on the strip and applying holder type of screen or foil on a wet solution before drying, and 2) the layering of the holder of the screen or foil on a sheet or Mat of tobacco aromatic bases with an appropriate adhesive.

Preferred currently, tobacco film manufactured using the manufacturing process of paper. During this process, tobacco film is washed with water. In the last step of covering use of soluble substances. The remaining (extracted) tobacco fiber used in the construction of the main litter. Water dispersed carbon fiber and add the sodium alginate. To give strength tobacco film 57, instead of sodium alginate can add any other hydrocolloid, which does not interfere with the response to the feeling of flavored tobacco, soluble in water and has a suitable molecular weight. The dispersion is mixed with a suspension of extracted tobacco fibers and optional odorous substances. The resulting mixture is put in the wet on a long net, and the film pass the matter, removed by washing the tobacco belt, put on one side of the film base, preferably via a standard reversing roller mill, located after the dryer or large drying cylinder samojedny machine. The ratio between soluble tobacco and dust and tobacco particles preferably ranges between 1:1 and 20:1. Bedding basics you can also pour or ekstradiroval liquid mass. Alternatively, create an offline phase coating. During or after the stage of coating add aromatic substances which are customary in the technology of production of cigarettes substances. To improve the ability to perceive the coating liquid mass, add pectin or other hydrocolloids, preferably in the range between 0.1% and 2.0%.

Whatever type of holder 59 is not used tobacco flavorful material 61, which is applied on the inner surface of the holder, allocates aromas when heated and is able to stick to the surface of the holder. Such materials include continuous tapes, foams, gels, dried liquid mass or dried applied by spraying a liquid mixture, which preferably, though not necessarily, contain TA is SS="ptx2">

During processing, tobacco film 57 preferably add a humectant, such as glycerin or propylene glycol, in amounts comprising from 0.5% to 10% of the humidifier by weight of the film. Humidifier facilitates the formation of a visible aerosols due to the action as a precursor aerosols. When a smoker exhales the aerosol containing the substance, creating a feeling of flavored tobacco and humidifier, the humidifier condenses in the atmosphere and condensed humidifier provides the appearance of a conventional cigarette smoke.

The cigarette 23 is preferably essentially constant diameter along its length and, like regular cigarettes, preferably has a length of between about 7.5 and 8.5 mm, so that the smoker in the case of the Smoking system 21 has a "mouth feel" similar to the feeling of the usual cigarettes. In the preferred in the present embodiment, the cigarette 23 has an overall length of 58 mm, thereby facilitating the use of conventional packaging machines in the packaging of such cigarettes. The total length of the double filter 71 and the second filter free flow 73 is preferably 30 mm Covering paper 75 preferably takes place at 5 mm beyond the end of the second filter free p tobacco film 57 are retained by the filter backwash 63, the length of which is preferably equal to 7 mm, and the first filter free flow 65, the length of which is preferably equal to 7 mm, the length of the cavity 79 defined in tobacco film 57, the filter backwash 63 and the first filter free flow 65, preferably equal to 14 mm

When the inserted cigarette 23 in the hole 27 in the first end 29 of the lighter 25, it abuts, or nearly abuts the inner surface 81 of the spacer sleeve 49 of the clamp heater on the sleeve 110 (Fig. 3) close with a passage 47 connecting with the driven air flow sensor 45 and a hole 55 for the light sensor 53. In this position, the cavity 79 of the cigarette 23 preferably is located next to the heater blades 120, and essentially all this part of the cigarette that includes a second filter free flow 73 and double filter 71 passes out of the lighter 25. Part of the heater blades 120 are preferably shifted in the radial direction inward to facilitate holding the cigarette 23 in position relative to the lighter 25 and thus that they are in heat transfer communication with the tobacco film 57, either directly or through brown paper 69. In line with this, the cigarette 23 preferably is able to compress the elements of the clamping device of the heater 39 are identical to the elements, described in the patent application WO 94/06314.

The transmission of air through the cigarette 23 is performed in several ways. For example, shown in Fig. 2 embodiment, the cigarette 23, wrapping paper 69 and tobacco film 57 are sufficiently permeable to air, to obtain the required resistance to retraction, so that when the smoker puffs on his cigarette, the air flows into the cavity 79 in the transverse or radial direction relative to the wrapping paper and tobacco film. As noted above, the air-permeable filter backwash 69 can be used to provide longitudinal air flow into the cavity 79.

If desired, the transverse flow of air into the cavity 79 is facilitated by providing a series of radial perforations (not shown) through brown paper 69 and tobacco film 57 in one or more areas near the cavity. Notice that such perforations improve the perceived feeling of flavored tobacco and the formation of aerosols. In tobacco film 57 provide perforations, having a density of about 1 hole 1-2 square mm and the hole diameter is between 0.4 and 0.7 mm, This gives a preferred CORESTA porosity equal 100-500. Wrapping paper 69 poetic area, for example, resistance to retraction, you can use the density of the perforations and the respective hole diameters that differ from those described above.

The cross-flow of air into the cavity 79 is facilitated by the provision of perforations (not shown) and through the wrapping paper 69 and through the tobacco film 57. In the manufacture of cigarettes 23 having such perforation, wrapping paper 69 and tobacco film 57 are attached to each other, and then perforined together, or perforined separately, and then attached to each other so that the perforations in each match or overlap.

The currently favored options of the heaters shown in Fig. 3-14. These heaters provide superior mechanical strength in the case of repeated vstavlenii, regulations and seizures of cigarettes 23, and significantly reduce the release of aerosols from the heated cigarette in order to reduce impacts on sensitive elements of the condensate. If not provided, the control unit condensate, produced aerosols tend to condense on the relatively cold surfaces, for example, on the pins of the heater 99A and 99B, the sleeve of the heater 110, the outer sleeve, the electrical soy is. is obnaruzhili that produced aerosols tend to flow radially inward from the pulse heater.

Usually preferably there are eight of the heater blades 120 to provide eight puffs sequential ignition of the heating elements 122, thereby simulating the expense puffs conventional cigarettes, and, accordingly, eight of the barrier blades 220. In particular, the heater blades 120 and the barrier blades 220 are held between the opposite end bushings 110 and 210, respectively, are interlaced or interwoven to form a cylindrical device alternating heating and barrage of blades. Between each adjacent heater blade 120 and the barrier blade 220 preferably form the gaps 130 and 135.

As particularly shown in Fig. 3-5 heater, provided with a metal substrate 300 in the form of a cylindrical tube, because the metal is more flexible, has better stress tolerance than ceramics, and, as described below, is electrically conductive. Selected for the substrate 300 metal made mechanically strong, allowing you to give the below form, and is heat-resistant material or shall I mark) and sheet alloy Inconel 625. A metal tube and a substrate 300 can be made from alloy in the form of sheet, rod or bar, for example, by drawing. Metal tube preferably design of Nickel - aluminum (Ni3Al) alloy. Alternatively, you can use a different alloy of Nickel and iron or aluminum, and iron (Fe3AI). As described below, the substrate 300 is made such that its thickness was approximately 3-5 mils (7,6210-2-12,710-2mm).

The metal substrate is made in such a way that it preferably has an essentially tubular or cylindrical shape. As best seen in Fig. 4, there is a tube 350 with a generally circular open the inserted cone 360 neck 365, which directs the inserted cigarette to coaxially positioned cylindrical receiver CR, the diameter of which is smaller than the diameter of the end of the 360. The diameter of the input end 360 is preferably larger than the diameter of the inserted cigarette 23 for guiding the cigarettes to the receiver CR, and the diameter of the receiver CR is approximately equal to the diameter of a cigarette 23 in order to guarantee the fit of the slide for a good transmission of heat. In the presence of acceptable tolerances of manufacture of the cigarette 23, gradually tapering plot the compression cigarettes to increase thermal contact with the surrounding substrate 300, serving as the inner wall of the receiver. The blades 120 are preferably bent inward to increase thermal contact with a cigarette by constructing diameter of the cylindrical receiver. The opposite end of the tube determines thermal sleeve 110 having any suitable diameter. As can be seen in Fig. 4, to determine the round sleeve 210 is placed layers 300. Alternatively, the layers 300, you can continue to expand outward in the form of elongation of the curvature of the neck of 365. This cone-shaped hole entered a separate sleeve 210. Alternatively or additionally, in a similar way it is possible to form the layer 300, which is in electrical contact with a separate sleeve 110, forming a common item.

The metal tube is applied ceramic layer 310 for electrical isolation caused after this electric heater 122 from the metallic substrate 300 of the tube, except for the ring or sleeve 110, which is located at one end of the tube. Ceramic preferably has a relatively high dielectric constant. You can use any suitable electrical insulator, for example, aluminum oxide, zirconium dioxide, mulit, cordierite, spinel, fosterite, wow expansion which closely matches the coefficient below the metal tube, in order to avoid differences in the intensity of expansion and contraction during heating and cooling, thereby avoiding cracking and/or rasslaivanie during operation. Ceramic layer remains physically and chemically stable when heated heating element. The thickness of the electrical insulator is preferred, for example, approximately 0.1 to 10 mil (0,25410-2-25,410-2mm), or about 0.56 to Mila (1,4210-2mm) and more preferably 1-3 mils (2,5410-2-7,6210-2mm).

For thermal and electrical isolation of adjacent heating elements in the substrate 300 and any covering layers provide gaps 130 and 135. The gaps 130 can run in parallel relative to the longitudinal axis of the tube and the gap 135 can go in the transverse direction. Alternatively, as shown in Fig. 9, the gaps may be in a spiral along the cylindrical tube. Depending on conditions, you can use any desired type spiral, corresponding to the gaps do not overlap, and areas of limited clearance, essentially equal to determine roughly equal sections that are thermally in contact with the inserted cigarette for the required heating and uniformly generated puffs. the major gaps provide the advantage of heating only small segments, running in the longitudinal direction of the line gluing cigarettes. If you use running in the longitudinal direction of the gaps, one heated area are likely to be aligned with glue may produce a subjectively undesirable odors.

Now will be described a preferred method of manufacture. A cylindrical tube made of a selected material having an appropriate length and wall thickness approximately equal to 1-10 Milam (0,25410-2-25,410-2mm) and preferably 3-5 Milam (7,6210-2-12,710-2mm), formed in a required shape. The mass of the tube decreases with decreasing thickness, reducing the weight of the device and the electric power required for sufficient heating of the heater blades 120 and inserted cigarette, which further reduces the weight of the unit as the power source, e.g. batteries, you can use smaller sizes.

Preferred are two options for implementation, which differ in the sequence of stages in the deposition of ceramic coatings and education blades. In the first variant 1) make the tube using, for example, stamping or extrusion; 2) put layers of ceramics and heater; 3) is Yes. These stages are described in more detail below. In the second variant 1) make the tube using, for example, stamping or extruding; 2) form a blade through, for example, sheet metal forming, EDM (electrical discharge machining (EDM) or laser cutting; 3) put a layer of ceramic and heating layers, and 4) connect the heating and electrical wiring. The second option allows you to form a blade through sheet metal forming, which eliminates unwanted burrs created by laser cutting. This stamping is possible because the ceramic layer is not yet done. In the first embodiment, the heater blades 120 may be formed by cutting through the ceramic layer and below the metal substrate through, for example, laser cutting. Alternatively, the metal sheet is punched to form blades before stamping round sheet to form a tube or Curling of the sheet into a tube and the joint implementation of the above steps 3 and 4. Alternatively, provide a thin tube having a wall thickness of approximately 3 to 5 Milam (7,6210-2-12,710-2mm) with sufficient initial diameter. Troika hot pressing to form a desired configuration of substrate size and bushings (bushings). The next stages are performed for the formation of the heating blades, as described above. As you know, before you perform each of the stages of application of the ceramic heater and apply the appropriate steps of applying a masking coating to determine areas of application. Defined here the production stages can be performed in any desired sequence with the purpose of achieving speeds of production, economies of materials, etc.

For example, as shown in Fig. 4, applied to the tube heater thickness of 3 mils (7,6210-2mm) manufactured as described above, and it was applied energy pulses, equal to about 22-23 Joule. A temperature sufficient for heating the blades, approximately between 800 and 900oC. for Example, the tube preferably punched or design to identify the remote end of the 360 in the form of a socket and the sleeve 110 and tapering to a smaller magnitude plot, which ultimately defines a cylindrical receiver CR. In the tube formed by the slits to determine thermally and electrically insulating gaps 130 and 135. These processes are preferably formed from a transition area between the sleeve 210 of the end of the Intro and middle section, about the limits of applied ceramic layer 310 and the sleeve 210, and for a short distance in a common sleeve 110 outside eventually caused the heater. This distance should be large enough not to loosen the sleeve. Enough in this case, a distance equal to approximately 0.5 mm

Alternatively, the slots can be cut by rotating the tube relative to a laser. Running in the longitudinal direction of the slit cut through the relative movement of the laser and the tube relative to the longitudinal axis of the tube. Spiral slits cut through the rotation of the tube relative to the laser and promotion of the laser relative to the longitudinal axis of the tube. In addition, to avoid the above line gluing cigarettes, spiral slots formed through the rotation can be facilitated at the end of manufacture, if the receiver also rotate and move relative to the stationary laser.

Then the tube is applied electrically insulating ceramic layer 310, except the terminal end 110 to provide the possibility of connecting wires. As noted above, in the first embodiment, it may precede the formation of the blades. More specifically, the ceramic layer, the thickness of Procida zirconium and in particular, Zirconia partially stabilized around 20% and, more specifically, 80% of yttrium oxide by thermal method is applied by plasma coating, if the surface is rough enough on the tube, which preferably rotate at the time of this application. In order to apply the correct floor, the tube preferably turn several times during coating. In addition, the end portion of the sleeve 210 of the substrate 300, if the sleeve is not being coated to provide a contact area for the heating element 122.

The surface roughness of the metal layer 300 is preferably increased to ensure better adhesion to the deposited ceramic layer 310. First, the surface layer 300 thickness make rough by using appropriate technology, for example, blasting steel grit, and then apply a binder coating. Binder coating is a thin, for example, a thickness of 0.1-5 mils (0,25410-2- 12,710-2mm) and preferably 0.5 to 1.0 mils (1,2710-2-2,5410-2mm), a layer of metallic coating type FeCrAlY, NiCrAlY, Ni, CR, Ni3Al or NiAl and provides a good bonding surface of contact between-the willow, in addition to thermal sprayed using other application methods, and more specifically, plasma spraying. For example, physical coating by deposition from the vapor chemical coating by deposition from the vapor, thick-film technology with screen printing a dielectric paste and sintering, Sol-gel technique, in which the Sol-gel is applied and then heated up to formation of hard coatings, and chemical deposition with subsequent heating. To create a bending strength is preferably used chemical binding.

Chemical binding is achieved by heating the ceramic layer or a ceramic intermediate product with a metal substrate at a relatively high temperature. Alternatively, the metal substrate is heated at a high temperature to form an oxide layer on the surface, which is done similarly to the ceramic layer.

Then put the heating element 122. You can use any appropriate metal or alloy intermetallic and/or ceramic additives in powder form, if required by application technique. More specifically, the applied layer is in NiCr, Ni3Al, NiAI, Fe3Al or FeCrAI by any known method of thermal spraying, type plasma coating or HVOF (high oxidative). The resistivity of the resistive material can be adjusted by adding appropriate ceramic or through regulation of the level of oxidation of the metal during the plasma or HVOF coatings. You can use thin-film methods, for example, CVD (chemical vapor deposition from a gas environment) or PVD (physical deposition from the gas environment), if the surface roughness of the ceramic layer containing a relatively large ceramic particles compared to particles of the material of the heater, to smooth through, for example, diamond grinding to a surface roughness between 135 and 160 microinches Ra (3,4310-2-4,0610-2mm Ra) with an average of 145 microinches (3,6810-3mm) Ra. This method requires more than a thin layer of metal to obtain the desired heater with a smaller mass. However, the process is slower. You can use any metal, for example platinum. Heaters can be applied during the rotation of the tube with a ceramic coating.

Now will be described two preferred option Khujand the creation of the mounted heaters. In the first embodiment, the substrate 300 is made of a Nickel-aluminum alloy (Ni3Al), a ceramic layer, a 300 - zirconium oxide (CrO) is preferably stabilized by yttrium oxide in a ratio of preferably about 8% yttrium, and the heating element 122 is sprayed from the heat method Ni3Al or NiAl. In the second embodiment, the substrate 300 is made from aluminide iron (Fe3Al), a ceramic layer 310 - zirconium oxide, preferably stabilized with yttrium oxide, in a ratio of about 8% yttrium oxide, and heating element 122 is sprayed from the heat method Fe3Al. If necessary, in an alternative implementation options you can use the material of the heating element of one variant with a substrate material other option.

Now will be described in more detail the preferred option, with reference to the first variant, which uses aluminide Nickel. This description applies also to the second option, which uses aluminide iron. Aluminum preferably contains between about 16 and 50 atomic percent, compared with less than 1 atomic percent in many industrial alloys.

Podlog the ke tube from Ni3AI or sheet Ni3AI. The substrate 300 can also produce by means of thermal spraying layer prepared from Ni3Al coal rods or tubes. As a support for the layer of the substrate 300 is also possible to use aluminum. The substrate 300 can also produce by submitting powders of Ni and Al in a proper ratio to form alloy Ni3Al. When applying powders through the plasma thermal spray powders react in such a way that a significant amount of released heat. The formation of the alloy occurs when the resulting spray into the surface. The process of obtaining the alloy can be improved through the use of mechanical alloy powders of Nickel and aluminum. Subsequent heat treatment gives Ni3Al and excellent links with the subsequently applied layer of insulator 310.

The insulator 310 may be an electrical insulator, which has electrical and thermal resistance and is glued to the substrate 300.

You should consider a bad mix of thermal expansion between the insulator 310 and the substrate 300 and the heater layer 122. You can use any suitable ceramic-type oxide is a new frontier and applicable to various configurations, especially dioxide Zirconia, partially stabilized approximately 8% yttrium oxide.

Because of high resistance is a necessary property for electric heating portable rechargeable batteries to provide resistive heating layer 122 prefer thermal spraying. The sputtering can be performed using various methods of thermal spraying. You can use pre-made alloy Ni3Al, mechanical alloy Ni3Al or powders of Ni and Al in the proper proportions. If spraying use mechanically prepared Ni3Al or powders of Ni and Al, it is a necessary stage of preheating. Temperature and preheating time depends on the parameters of thermal spray gun and can be regulated so that the temperature was in the range from 600oC to 1000oC. If the formation of Ni3Al is not used pre-prepared Ni3Al, are important dimensions of the particles and their distribution by size. For the purpose of providing resistance you can use the structure of NiAl. As additions to alloys Ni3AI you can use multiple elements. The main additions to the alloy which is more effective when Ni3AI is rich in Nickel, for example, when Al 24 atomic percent. Silicon is added to the alloys Ni3AI in small quantities, because adding more silicon up to 3% by weight forms silicides of Nickel and the oxidation leads to the formation of SiOx. The addition of molybdenum (Mo) increases the strength at high and low temperatures. Zirconium helps to improve the resistance to cracking of the oxide during cyclic temperature changes. To improve the heat resistance can also add hafnium (Hf). The preferred alloy Ni3Al for use as a substrate 300 and a resistive heater 122 is denoted by 1C-50. In the work of the Century Sicca Processing of intermetallic aluminides", presented in the journal "Intermetallic metallurgy and processing of intermetallic compounds" (Intermetallic Metallurgy and Processing of Intermetallic Compounds, edited by Stiopa and others , van Nostrand country Director Mr Reinhold, new York, 1994, table 4 shows that the alloy consists of about 77,92% Ni (Nickel), 21,73% Al (aluminum), 0,34% Zr (zirconium) and 0.01% of B (boron). To aluminide iron you can add different elements. Possible additives may be Nb, si, TA, Zr, Ti, Mn, Si, Mo and Ni.

If you want smelting of any alloy, the eat to the resistive heater 122 or the substrate 300, as described above, using laser yttrium aluminium garnet (YAG) or laser carbon dioxide (CO2). Soldering can be performed copper-silver or copper-Nickel and hard alloys. For these purposes it is preferable brazing compared to high-temperature soldering and welding, since the thickness of the resistor is less than 5 mils (0.005 inch) or 125 μm. For surface wetting and cleaning of oxides can be used flux. Firms "Likas-Milhaud s Wisconsin" and the firm "Indium Corporation s America" there are several such brazing alloys. Copper-silver solders have optimal temperatures of solidus and liquidus in the case of brazing laser heater without penetration through the layers, since the total thickness of the heater 122, the insulator 310, the substrate 300 is in the range of 10-15 mils (25,410-2-38,310-2mm).

The present invention provides a multi-layered heater with Ni3Al the substrate and the heater, separated by insulator Zirconia. The concept of normal and it can be used on different thickness for different configurations. Alloy Ni3Al readily forms on the surface of the adhesive layer of aluminum oxide thereby cyclic service life of the material.

As shown in Fig. 4 and 5, the end of the marked heater 122 is in close electrical contact with the underlying metal substrate 300 near section 125, and the remainder of the heating element 122 covers the ceramic insulating layer 310. Plasma coating of each resistive heating element 122 of the metal substrate 300 provides a reliable contact. In line with this, formed the General electric item, consisting of terminal bushings 110 and electrically conductive metal substrate 300 each heater blades 120, which is connected to one end, for example, the remote end of each respective heating element. Sleeve 110 that serves as a common part, electrically connected to the power supply via pin 99B, as shown in Fig. 3.

On the heating element 120 after just sprayed material 128 having a high conductivity, for example, Nickel, Nickel alloys, copper or aluminum, and then the conductors, for example, pins 99A, attach, for example, by welding, brazing or soldering, to the opposite end, for example, closest to the near end of the sleeve 110 of the heating alemu soldering silver, instead described below connecting pin 99A. The highly conductive material 128 makes the underlying plot is less resistive and makes it easier to attach the wires as described above.

The tube form or to get one of the metal sleeve 110 at one end, as shown in Fig. 8, or it is preferable to provide an additional sleeve at the opposite end 210, as shown in Fig. 6A-7. Since the substrate using the metal heater blades 120 can be shifted inside, preferably before adding the layer 310 and any curl in the direction of the inserted cigarette, to improve the distribution of heat, i.e. thermal contact between these elements without the risk of fracture associated with ceramic blades. In addition, educated shovel and put the heater are bending in the form of the tube, additionally increases the contact with the inserted cylindrical cigarette. The width of the blades may be, for example, 1.5 mm

In one embodiment of the invention shown in Fig. 6A and 6B, each of the second station or the blade 120 with ceramic coating bounded on opposite sides of the gap 135 tube is still alternating between sections 120 of the heating blades. These blades 220 function as a layer to prevent leakage of vapors from the heated cigarette that cause potentially damaging condensation. In this embodiment of the invention is provided twice, for example, sixteen, the number of gaps compared to the number of puffs, for example, equal to eight, to determine adequate and equal number of heating blades and nagrevaemykh barrage of blades.

You may need to change the number of puffs, and hence the number of the heaters 122, resulting from the insertion of the cigarette into the cylindrical receiver CR. This required amount is achieved through education required number of heater blades 120 and the respective barrier blades 220. This can be achieved by separating the tube at equal or different sizes of blades. As described above, between each adjacent heater blade 120 and the barrier blade 220 is defined gaps 130 and 135. These gaps form through a minor cut or trimming one group or both groups barrage or heating blades. The size of the gaps 130 and 135 do rises the more blades on the adjacent barrier blades, and quite small or narrow to prevent the release of significant quantities of vapor from the cylindrical receiver. For example, in many cases sufficient there is a gap of approximately 5-15 Milam (12,710-2-38,310-2mm) or less and preferably about 3-4 Milam (7,6210-2-10,1610-2mm).

In the one shown in Fig. 6A and 6B, the embodiment of the invention each second plot or the blade 120 with ceramic floor, bounded on opposite sides of the gap 135 of the tube caused the heating element 122. In line with this, formed by alternating vanes 220, which comb intertwined between the alternating sections of the heater blades 120. These blades 220 function as a barrier to prevent release of vapor from the heated cigarettes, which can create potentially damaging condensation. In this embodiment of the invention is provided twice, for example, sixteen gaps, compared to the number of puffs, for example, equal to eight, to ensure adequate and equal number of heating blades and nagrevatelnyh barrage of blades.

Can okashii cigarettes in the cylindrical receiver CR. It required number of receive through education required number of heater blades 120 and associated barrier blades 220. This can be obtained by cutting the tube at equal or unequal sizes of the scapula.

As described above, between adjacent heater blade 120 and the barrier blade 220 is formed gaps 130 and 135. These gaps form through a minor cut or cutting of one group or both groups barrage or heating blades. The sizes of the gaps 130, 135 are doing enough or wide enough to prevent loss of heat during pulse receiving heat from the heated heating the blades on the adjacent barrier blade and a fairly small or narrow to prevent leakage of sufficient quantities of steam from the cylindrical receiver. For example, in many cases acceptable gap is approximately 5-15 Milam (12,710-2-38,310-2mm) or less, and preferably 3-4 Milam (7,6210-2-10,1610-2mm).

After the pulse heating of the heating element 122 has a predetermined minimum time before it will be possible for the ve barrier blades 220 next to the heated pulse follows heater blade 120 also act as heat sinks to prevent the spread of heat to the other heater blades 120 or unheated or previously heated portions of the inserted cigarette 23. Premature heating of the plot cigarettes can lead to undesirable and/or partial production of aerosols or generated heat deterioration plot cigarette before the required heat. Subsequent re-heating the previously heated area may result in the release of undesirable smells or tastes. To get this feature of the heat sink, the barrier blades include a layer of non-conductive heat of the material, i.e., the heat insulator ceramics. Examples of suitable ceramics include aluminum oxide, zirconium dioxide, a mixture of aluminum oxide and zirconium dioxide, aluminium silicate, and so forth, as is the case in respect of the heating blades.

If you want a longer delay than is obtained using a pulsed heating of one heater and a corresponding heating of the blade, then the control logic design to ignite another heater or auxiliary heater (heaters) immediately after the pulse heating of the initial heater, or during the final part of the initial pulse energy supply, heat another segment of the cigarette. Additional heater may be further in the radial direction is ary desired number of puffs required duration.

In another embodiment of the invention, in which the end of the heater shown in Fig. 8, the tube contains one sleeve 110 having many, for example, as shown in the figure, eight blades with corresponding gaps 130 between them. As described above, alternate vanes cause the heating elements 122 that define the heater blades 120, whereas the other located between the blades do not cause the heating elements and define them as the barrier blades 220.

As shown in Fig. 7, all sites limited clearances, can function as a heater blades 120. In one embodiment of the invention each section or blade with a ceramic coating is applied thereto the heating element 122, and the number of heater blades 120 corresponds to the number of puffs, for example, eight. In another embodiment of the invention each area with ceramic coating has a heating element, and the number of educated heater blades 120 twice the number of puffs, for example, there are sixteen areas with heaters to eight puffs of the cigarette. This configuration allows osushestvila 2 seconds, and preferably consistent in the radial direction of the firing order in cases of a variant in which the number of heating elements 122 corresponds to the number of puffs. For example, logic may dictate that two opposite Each other around the circumference of the heating element 122, i.e., heating elements, spaced 180oon the tube was lit at the same time, with the aim of simultaneous heating of sufficient magnitude cigarettes for generating torque. Alternatively, after the first sequence of ignition of each of the second heating element 122 for cigarette, followed by a second sequence plugs in between the heating elements 122 for the next cigarette. Alternatively, this first ignition sequence can be repeated within a predetermined period of existence of large number of cigarettes, and then to initiate the second sequence of ignition. You can use any combination of the heating of the blades and, if necessary, the barrier blades. The number of heating blades may be less than, equal to, or greater than the number of puffs one used cigarettes. Such is the SCP of the six heaters lit for each subsequent cigarettes, and the corresponding group of the remaining three heaters does not illuminate.

The use of metal as a substrate allows the metal substrate 300 of each of the heater blades 120 to serve as a pathway, for example, the negative connection for the heating element 122. More specifically, one end of the heating element is electrically connected, for example, by plasma spraying, located at the bottom of the metal substrate 125. This end of the heater preferably is a closer inserted to the open end of the 360, than to the other end of the heater, since the connection of the heater does not contain electrical wires, which could be damaged during the insertion and withdrawal of the cigarettes, the metal sleeve 110 is fed a negative charge from the power source 37 and the sleeve serves as a common item for all heating elements. More specifically, the sleeve 110 is electrically connected to the negative terminal of the power source 37 through the pin 99B connected and preferably welded thereto, as shown in Fig. 3. Pin 99B, in turn, connected to a power source 37 through the pin 104B. From what edstam, for example, electrical wire, type the pin 99A, connected by spot welding, brazing or soldering to section 128 of the heating elements 122. The pin 99A electrically connected to the positive terminal of the power source 37 through the pin 104A. Section 128 is made from any suitable material, for example, Nickel, aluminum or corresponding alloys 50:50 Nickel and aluminum, copper, etc. having good adhesion and a lower melting point than the metal layer 300.

The present invention also minimizes potentially damaging induced heat stress. The heating element is essentially evenly applied on the ceramic support, thereby avoiding stresses arising from the mutual connection of discrete sections of the heating element and/or from discrete mutual connections between the heating elements and ceramics.

As described above, in order to simplify the manufacture of heating elements 122 are preferably applied to the outer surface of the heater blades 120, i.e., on the blade surface, opposite the surface in contact with the inserted cigarette 23 or nicholaou surface is formed of a relatively strong support for the heating elements, and eliminated the immediate strong interaction of the heating element with a cigarette during insertion, any preliminary adjustment, or removal of a cigarette smoker. The advantage of the mechanical configuration requires that the heating element 122 is heated below the ceramic layer 310 and the metal substrate 300 that is in contact with the inserted cigarette, to transfer heat by conduction to the inserted cigarette and, secondly, by conduction and radiation between the heated pulses heater blade 120 and inserted a cigarette is not saved convenient surface section. The heating element 122 preferably has such a size and design in thermal relation so that it was heated for the most part below the heater blades 120, to heat in the end of the segment is inserted cigarette, having a sufficient amount equal to, for example, 18 mm2, for generating acceptable torque for the smoker. The heat transfer from the heating element 122 should not suffer significant inefficiencies because the heater takes a pulse of heating energy through the comparator is eat thickness between about 1 and 2 Miami (2,5410-2-5,0810-2mm). The heating element may be made of the previously mentioned MCrAlY alloys, FeCrAlY, nichrome (the brand name of alloys containing 54-80% Nickel, 10-20% chromium, 7-27% of iron, 0-11% copper, 0-5% manganese, 0.3 to 4.6% of silicon and sometimes 1% molybdenum and 0.25% titanium: Nichrome 1 consists of 60% Nickel, 25% iron, 11% chromium and 2% manganese; Nichrome II consists of 75% Nickel, 22% iron, 11% chromium and 2% manganese, and Nichrome III is heat-resistant alloy containing 85% Nickel and 15% chromium) or aluminides. In addition, the ceramic layer having a relatively low thermal conductivity, does not conduct sufficient heat to the associated sleeve. The metal layer due to the presence of higher thermal conductivity, also does not provide sufficient conductivity, for example, more than about 5-10%, due to the short pulse duration and a small cross-section.

It was determined that mainly transverse or radial flow of air relative to the inserted cigarette gives more desirable the production of smoke, than essentially longitudinal flow. The gaps 130 and 135 provide the path for drawing air into contact with the inserted cigarette. To optimize the cross flow of air is provided dopolniteolnyh blades. The perforation is preferably carried out by laser after application of the ceramic coating 310 and the heating of the coating 122, or by mechanical punching before use. To avoid printing or punching of the heating blade before applying the heating elements or punching of the heating blades after application, you can make a single perforation of the barrier blades, if the gaps pass sufficient air flow.

As described above, to avoid heating of the adjacent blades and to minimize condensation of vapours are gaps 130, 135. In addition, these gaps allow for thermal expansion of the heater blades 120 and the barrier blades 220. In the previously described embodiments of the invention, which uses one sleeve (Fig. 8), to compensate for temperature induced changes in the size, there are gaps 130, 135 between the longitudinal sides of adjacent blades.

Longitudinal changes allowed, because the ends of the blades opposite to the one of the sleeve are free. In the above-described embodiments of the invention with two bushings, gaps 130 and 135 are determined is by and between the round or square free ends of the blades and the opposite sleeve 210.

In the form shown in Fig. 6A embodiment of the invention, gaps 130 are only along the longitudinal sides of the adjacent comb bound by way of the heater blades 120 and the barrier blades 220 is limited on both ends of the respective bushings 110 and 210. Tube 110 is not covered with a ceramic coating 310, i.e., the metal substrate 300 is opened, so that the sleeve 110 functions as a General item for the heating elements 122. Sleeve 110 defines a hole 360, which is not expanded in this embodiment of the invention. In Fig. 6B shows an alternative embodiment of the invention, except that the gaps 135 are U-shaped. Each of the barrier blades 220 are formed in one piece with both bushings 110 and 210 and the heater blades 120 are away from the sleeve 110. This form of gap, when one end of the blade is free relative to the opposite sleeve, allows you to be thermal expansion and contraction of the heater blades 120 in the longitudinal direction, thereby reducing the voltage.

In Fig. 8 shows another variant in which there is no sleeve 210, which determines the insertion 360. The introductory hole 360 is defined by the free ends n the sleeve 110. The free ends of the blades allow the blades to expand, to reduce undesirable excessive deflection or displacement of the blades inside, originating from thermal expansion. Excessive offset inside reduces the internal diameter of the cylindrical receiver CR, thereby potentially damaging the force required for insertion and withdrawal of the cigarettes. In addition, the free ends of the blades mainly reduce the required effort for the insertion, since the free ends sealed at one end (cantilever) relative to the sleeve. Next, as shown in this embodiment of the invention, the width of the heating and the barrier blades may not be the same. The heater blade 120 in any case has a width of approximately 1.5 mm

Now be considered an alternative with reference to Fig. 10, in which the heaters 122 deposited on the inner side of the heater blades 120, i.e., the surface that defines the cylindrical receiver CR, so that the heaters 122 in direct contact with the inserted cigarette or tightly surrounded her. As can be seen in Fig. 10, the ceramic layer 310 is located inside a metal layer 300 blades 120 and the heater 122 location of heaters can be used in any of the disclosed embodiments of the invention. The method of constructing such a configuration may enable the formation of the blades, causing the ceramic heating layer in any of the above order on a metal sheet, and then twisting and welding closed shape to form a tube, in which the heaters 122 are located on the inner side of the blades 120, converted to an inserted cigarette.

More specifically, this manufacturing method includes stamping the metal sheet thereby to form a set of blades 120, 220 (if you are using the barrier blades 220), running perpendicular from the connecting section CS in such a comb device, as shown in Fig. 11. This device is provided with a mask and unprotected blades and, if necessary, by connecting the CS site, put insulating ceramic layer. Further, the device is again covered with a mask and cause resistive heating elements 122, for example, by screen printing on the selected blades. Then attach connecting wires. Further, the heating device is twisted so that the connecting section CS formed the General electric bushing 110, as described above. After twisting connecting cheperegin converted to an inserted cigarette, as shown in Fig. 10, or after curl in the direction of the arrow is formed In the heating device, in which the heaters are located externally from the cigarette, i.e., the metal substrate 300 directly facing the cigarette, as shown in the drawings, for example, in Fig. 12.

Alternatively, the cylindrical configuration of the heaters can be formed by stamping stencil P, as shown in Fig. 13, from the corresponding sheet of conductive material. Stencil P includes a Central sleeve 410 having multiple spaced apart shoulders 420, running radially in the outer side of it, forming a device, like the spokes of a wheel. Shoulders 420 cover the insulating layer and the resistive heater, as described above. In one embodiment of the invention, the sleeve 410 serves as a General part, where each resistive heater, respectively, electric way connected to the corresponding shoulder 420, preferably at the end of the heater 122, the farthest away from the sleeve 410. Preferably on the end 122 of each of the heater closest to the sleeve 410, implemented appropriate positive contact, so that all connections, i.e., the positive is particularily the plane of the sleeve, defining a cylindrical receiver. Depending on the direction of bending, or the heaters 122, or shoulders 420 are converted to an inserted cigarette.

In any of the above embodiments of the invention can be used in common blade 320, as shown in Fig. 11 and 12, for electrical connection of the common sleeve 110 from the power supply through pin 99B. General blade 320 passes from the sleeve 110 in the same direction as the other blades, and are not covered neither pottery nor resistive heater at the time of manufacture, i.e., overall blade 120 concealed so that it became part of the substrate 300. Alternatively, the overall blade cover ceramics 310 to electrically isolate the common blade of the surrounding elements. In line with this, a negative contact for all heaters 122 is formed on the end of the total vanes 320, the total opposite of the sleeve 110. Similarly, the corresponding positive connection for each heater 122 is formed at the ends of the heater blades 120, opposite the sleeve 110, so that the electrical connections are at the end of the heating device, the total opposite of the sleeve 110. Thus, if necessary, the total is and the opposite end of the via, for example, spacers 49.

In any of the embodiments of the invention, the negative connection of each heater can be managed separately, via, for example, corresponding to the negative contact, deposited on the other end of the heater, which is the opposite end of the heater with the corresponding positive contact 128. Accordingly, in this embodiment of the invention shoulders and sleeves can be electrically non-conductive. In addition, in any of the embodiments of the invention one heater may include a blade or other structure having a layered configuration as described above, with the corresponding negative connection for heating the tobacco in cigarette form, as described above, moreover, the ordinary cigarettes, tobacco film Smoking articles described in undergoing simultaneous consideration of the application for a U.S. patent with registration N 105.346, filed on August 10, 1993.

In Fig. 14 shows another variant embodiment of the invention, in which the blades 120 contain more made in one piece segment 120A. For example, the length of the blades in Fig. 11 and shoulder in Fig. 13 can be increased, SK is agravates provide by coating a ceramic electrically insulating layer, for example, a sealing layer 310, a segment of the substrate 120A as described above, and then by coating the contact material 120A is electrically conductive end of the resistive heater 122 is covered with ceramics segment 120A. Alternatively, instead of the contact material 12 8A is used for the connecting wire or the path that is electrically isolated from the segment 120A of the scapula. The sleeve 110 and the heater blades 120 and, if necessary, the barrier blades 220, feature, as described with reference to Fig. 11 and 13. The segment blades 120A bend of approximately 180oso the end 122E, opposite the connection to the heater 120 is in close proximity to total sleeve 110 and electrically connects the corresponding pin 99A, to function as a positive terminal, provided that all electrical connections have towards the sleeve 110. A bent section between the section 120A and the section of blade 120, carrier heating element 122 may have a smaller width than the remainder of the blade. This bent blade can serve as elements of flexibility forms around the inserted cigarette, slightly widened during insertion to receive a cigarette, and then I designed to allow you to transfer an effective amount of tobacco flavor the smoker under standard conditions of use. In particular, it is clear that at the present time it is desirable to give the smoker between 5 and 13 mg, preferably between 7 and 10 mg, aerosols within 8 puffs, where each puff of 35 ml of torque, with a two-second duration. It was determined that to obtain such a supply, the heating elements 122 must be able to pass a temperature between approximately 200oC and about 900oC, in heat transfer when using the cigarette 23. Further, the heater blades 120 should consume preferably between about 5 and about 10 joules of energy, more preferably between about 10 and about 25 joules, and more preferably about 20 joules. Lower energy demand for the consumption of the heater blades 120, which are bent inwards towards the cigarette 23 in order to improve the communication of heat transfer.

The heating elements 122 having the required characteristics, it is preferable to have an active surface area of between about 3 mm2and about 25 mm2and preferably have a resistance between about approximately 0.8 Ohms and approximately 2.1 Ohms. The resistance of the heater, of course, is dictated by the specific power supply 37, which is used to provide the necessary electrical energy for heating the heating elements 122. For example, the above-mentioned resistance heating elements correspond to the invention, where the energy is supplied by four series-connected cadmium-Nickel battery batteries with a total voltage of the energy source with no load, equal to about 4.8 to 5.8 volts. In an alternative embodiment of the invention, if there are six or eight such cells connected in series rechargeable battery, the heating elements 122 should preferably have a resistance of between about 3 Ohms and about 5 Ohms, or between about 5 Ohms and about 7 Ohms, respectively.

The materials from which to fabricate the heating elements are preferably chosen so as to guarantee repeatable use at least 1800 cycles on-off without damage. The armature 39 of the heater preferably can be positioned separately from the lighter 25, including the source of elektrotom and other metal items are also chosen on the basis of their resistance to oxidation and the lack of their ability to join in a chemical reaction to ensure that they do not oxidize or otherwise react with the cigarette 23 at any temperature that can be achieved when Smoking. If required, the heating elements 122 and other metal parts are enclosed in a capsule of inert conductive heat material such as a suitable ceramic material, so as to further prevent oxidation and other reactions.

Based on these criteria, materials for electrical heating means includes a doped semiconductors (e.g. silicon), carbon, graphite, stainless steel, tantalum, metal matrix and metal alloys such as iron-containing alloys. Suitable ceramic materials include the carborundum carborundum aluminum and titanium. Suitable also resistant to oxidation of the intermetallic elements, for example, aluminides of Nickel and iron aluminides.

However, more preferably, the electrical heating elements 122 and other metal elements made of heat resistant alloy, which shows the combination of high mechanical strength and resistance to deterioration in the quality of the surface at high temperatures. The heater blade 120 is made from materials which exhibit high strength and surface stability at temperatures up to about 80% of their melting points. Such alloys include alloys, commonly known as superalloys and are usually based on Nickel, iron or cobalt. For example, suitable alloys, mainly, of iron or Nickel with aluminum and yttrium. Alloy heating elements 122 preferably includes aluminum to further improve characteristics of the heating element, for example, by providing resistance to oxidation. And the heating elements 122 and the metal substrate 300 sleeves and shoulder blades are preferably alloy or Ni3Al or Fe3Al.
