The present invention relates to Electrophotography Smoking system, which is placed in a substrate, forming an aerosol. In particular, the present invention relates to Electrophotography Smoking system for receiving aerosol forming substrate, in which the aerosol forming substrate is a liquid.

In some documents of the prior art, for example US-A-5060671, US-A-5388594, US-A-5505214, US-A-5591368, WO-A-2004/043175, EP-A-0358002 and WO-A-2007/131449 described electrical Smoking system having a number of advantages. One of the advantages is that they significantly reduce the side smoke, while allowing the smoker to selectively stop and resume Smoking.

Other documents of the prior art, such as EP-A-0295122, EP-A-1618803 and EP-A-1736065, disclose electrical Smoking system that uses a liquid as the aerosol forming substrate. The liquid can be contained in the cartridge, which is placed in the casing. Also include a power source such as a battery (battery)connected to a heater for heating the liquid substrate while tightening the purpose aerosol formation, provide the smoker.

Elektropodogreva Smoking systems proposed so far, including the ones described above, have a number of advantages, but there is still room for improvements, so what does the present invention to provide an improved Electrophotography Smoking system.

According to the first object of the invention is proposed Electrophotography Smoking system containing a shell and a replaceable mouthpiece and the cartridge case contains a power source and an electric circuit; the mouthpiece contains a section for storing the liquid, the capillary wick having a first end and a second end, the first end continues in the section for storing the liquid for contact with the contained fluid, at least one heating element for heating the second end of the capillary wick, the output of the air and the camera aerosol formation between the second end of the capillary wick and outlet for air; here when interacting cartridge and mouthpiece at least one heating element is in electrical connection with the power source through the circuit, and the circuit is designed for supplying pulse electric current on the at least one heating element when the user makes a puff, and a path for air flow is formed from at least one inlet for air to exit the air through the chamber aerosol formation, and this path directs air flow around the heating element and the second end of the capillary wick.

At least one inlet for air can be placed in a sleeve or in the mouthpiece. When using liquid p is remediesa of land for storage of fluid in the direction of the heating element due to capillary action in the capillary wick. After actuation of the heating element of the fluid at the second end of the capillary wick evaporates heating element with the formation of a supersaturated vapor. Saturated steam is mixed and transported by an air stream from at least one inlet for air to the chamber aerosol formation. In the chamber aerosol formation vapour will condense to form an aerosol which is transferred in the direction of the outlet of air to the mouth of the user.

Electrophotography Smoking system according to the invention has several advantages. First, because the removable mouthpiece comprises at least one heating element, the area for storing the liquid and the wick, all of the elements that may come into contact with the liquid are replaced when replacing the mouthpiece. Thus, no cross-contamination in the sleeve between different mouthpieces, for example, containing a different liquid. In addition, the liquid contained in the storage area of the liquid, protected from oxygen (because the oxygen can't get to the site for storage of liquid through the capillary wick) and, in some embodiments, run from the light, so that the risk of degradation of the fluid is greatly reduced. Therefore can support a high level of hygiene. Secondly, this design of the mouthpiece is designed for people who no risk of leakage from the storage site is fluid, which is quite possible in many electrophotograph Smoking systems of the prior art. This not only prevents fluid loss, but also makes the user unintended access to the fluid by separating the mouthpiece. In addition, if you change the mouthpiece at suitable intervals, it is unlikely that the heating element could become clogged with fluid. Thirdly, because the scheme transmits a current pulse at the time when the user starts tightening, and the air passes around the heating element and the second end of the capillary wick, there is an optimization of aerosol formation.

The invention will be described hereinafter only as an example with reference to the accompanying drawings, on which:

Fig. 1 - sleeve Electrophotography Smoking system according to a variant implementation of the present invention;

Fig. 2 - mouthpiece Electrophotography Smoking system according to a variant implementation of the present invention; and

Fig. 3 - Electrophotography Smoking system Assembly containing a sleeve according to Fig. 1 and the mouthpiece of Fig. 2.

In Fig. 1 shows the sleeve Electrophotography Smoking system according to one Varian is the implementation of the invention. The sleeve 101 includes a power source in the form of a battery 103, an electric circuit 105 and system 107 detection torque indicator torque 109, the electrical connection 111, the electrical contacts 113, inlets for air 115 and the locking mechanism 117. The sleeve is made to connect with the mouthpiece 201 in Fig. 2.

In Fig. 2 shows the mouthpiece Electrophotography Smoking system according to one variant implementation of the invention. The mouthpiece 201 contains a section for storage of a liquid in the form of a cartridge 203 containing liquid 205, the capillary wick 207, a heating element in the form of a heating coil 209, air outlet of 211 and the camera aerosol formation 213. The first end 207a of the capillary wick 207 continues cartridge 203, and the second end 207b of the capillary wick 207 is surrounded by a heating coil 209. The mouthpiece also includes a cap 215 to protect the second end 207b of the capillary wick 207 and the insulating ring 217. The mouthpiece 201 is intended for connection with the sleeve 101 in Fig. 1.

In Fig. 3 shows the sleeve 101 from Fig. 1, connected to the mouthpiece 201 from Fig. 2 for education Electrophotography Smoking system 301, adapted to supply the user with on-demand aerosol. The sleeve 101 and the mouthpiece 201 are fastened to each other with the possibility of separating the locking mechanism 117. The ends of the heating coil 209 are in contact with the electrical contact 113 on the sleeve. System 301 operates as follows.

Fluid 205 is transferred from the cartridge 203 from the first end 207a of the wick 207 to the second end 207b of the wick through capillary action. When the user draws air into the device at the outlet for air 211, ambient air is drawn through inlets for air 115. In this embodiment, the system 107 detection tightening perceives the tension, activates the heating coil 209 and includes indicator tightening 109. The battery 103 sends a pulse of energy to the heating coil 209 for heating the second end 207b of the wick 207. The fluid in the second end 207b of the wick 207 evaporates heating coil 209 for the formation of a supersaturated vapor. At the same time, the evaporated liquid is replaced with another fluid, moving in the direction of the second end 207b of the wick through capillary action, which is sometimes called the "suction effect". Received supersaturated vapor is mixed and transferred to the air flow from the inlets for air 115 in the direction of the camera aerosol formation 213. Due to the relative position of the inlets for air and mouthpiece 211 air flow is directed around the second end 207b of the wick in such a way as to optimize the formation of aerosol in the chamber aerosol formation 213. In the chamber aerosol formation 213 steam condenses to mod the education of the inhaled aerosol, which is transferred in the direction of exit 211 and to the mouth of the user.

In this embodiment, the circuit 105 and the system 107 is detected torque are programmable. Scheme 105 and system 107 detection torque can be used to control the operation of the device. In this embodiment, when the system 107 detects the tension, which makes the user, the battery sends a current pulse of a given duration to the heating coil 209. The specified duration of the current pulse will depend on the amount of fluid required for the same torque, and the time required for evaporation of this fluid. This, in turn, will depend on the properties of the liquid, the heating coil and the capillary wick. The specified duration may be from 0.5 to 3 seconds.

In this embodiment, the cartridge 203 in the mouthpiece shall be of such dimensions to contain a sufficient amount of fluid for a given number of puffs. After a specified number of puffs cartridge can be re-filled, but it is preferable to replace the entire mouthpiece. A specified number of puffs is ideally 200 to 2000 puffs, and depends on the desired dimensions of the cartridge, the mouthpiece and the entire device, as well as the properties of the used fluid. The cartridge 203 can be made of any suitable material. Examples VK is ucaut glass and plastic polymers, such as PET (polyethylene terephthalate) or others, which are used in food and pharmaceutical industries. The material should be selected so that the maximum extent possible to avoid leaks, breaks or misuse.

In variants of execution shown in Fig. 1-3, when the sleeve and the mouthpiece is connected, the cartridge 203 is located along the front of the second end 207b of the wick and heating coil 209. Thus, air from the environment is drawn through the inputs 115 and passes around the cartridge 203 until the air of the second end 207b of the wick and heating coil 209. However, in an alternative embodiment, the mouthpiece may be made in such a way that, when the sleeve and the mouthpiece is connected, the cartridge is located along the second end of the wick and heating coil. In this embodiment, the air from the environment is drawn through inlets for air, then vapor or aerosol will be held around the cartridge on the way to the exit for air.

The capillary wick may be made of various porous or capillary material and preferably has a known, fixed in advance capillarity. Examples include materials based on ceramics or graphite in the form of fibers or sintered powders. Fuses with different porosity can use is available for use with liquids, having different physical properties, such as density, viscosity, surface tension and vapor pressure. The wick should be suitable for submission to the heating coil, the desired amount of liquid.

The size and shape of the mouthpiece and sleeves are picked so that they could be interconnected with the formation of Electrophotography Smoking system suitable size that can be used by smokers. Components of the mouthpiece and the cartridge, including the power source, the schema section for storing fluid, the wick, the heating element and the chamber aerosol formation, are respectively selected size and shape, taking into account the design of the system. The system preferably is compact and can have dimensions similar to the dimensions of a conventional cigar or cigarette.

The system according to the invention allows to control the concentration of particles (mg/l or mg/amount of torque) in the aerosol particle size in the aerosol and distribution (range) size of the particles in the aerosol. These indicators can be controlled by varying one or more of the following indicators: the initial composition of the liquid, forming an aerosol, the transfer of energy (heat energy per unit surface area) in the heating element, the design of the chamber aerosol formation and operating temperature. The Perrin is with energy will depend on a number of factors, including the materials used in the heating element and wick, the diameter of the wick, the design of the heating element, including, in the case where the heating element is a spiral, length, diameter and pitch (the distance between the helices of the helix, and the energy supplied to the heating element.

The working temperature must be controlled so that to ensure the absence of unwanted degradation of the substances forming the aerosol, and aromatic material. This can be achieved, for example, by controlling the temperature of the heater if the heater is made of a suitable metal or alloy, using a variation of the conductivity or by controlling the amount of energy supplied to the heater. The preferred operating temperature of the heating element is in the range from 100 to 300C. the Layout shown on the drawings, may act in this temperature range and can also provide fast response time (the time between the user makes a tightening in the system and the flow of aerosol into the mouth of the user exit for the air, which may be referred to as "duration tightening")of from 10 to 500 MS.
