This invention relates to a smoke-generating compositions based polypropylenglycol.

Not so long ago were invented electronic devices to mimic tobacco Smoking (EBIT) (EN 2336002, publ. 20.10.2008, No. 29, No. 103062U, publ. 27.03.2011), generating steam or fog, which may or may not contain nicotine and when inhaled can cause taste of real tobacco smoke. AWIT produced in the form of cigarettes, cigars, pipes, etc. and are essentially the inhaler. The design of AWIT lies cartridge containing smoke (steam or fogging) of the liquid composition and vapor or tomanagement called an "atomizer" [US 2011/0011396 A1 (2011), US 783241082 (2010)].

There are two types of spray liquid. Atomiser with the heating element and the atomizer with an ultrasonic atomizer. Now the second type is used only in models from some manufacturers class penstyle. In all other cases, typically used atomizer heating element [http://www.ecig-news.ru/history/evolution-means/print:page,1,21-evolyuciya-elektronnoy-sigarety.html].

Some models of e-cigarettes have disposable evaporators. When they are included in the cartridge, so when you change the cartridge changing and heating elementdata design (cartridge+atomizer) is called a cartomizer [http://www.electro-dym.ru/.http://wwwcybersmoke.ru/index.php?category.].

Atomizers include in your design evaporator (heating element, for example, nichrome spiral) or ultrasonic nebulizer [http://www.ecig-news.ru/history/evolution-means/print:page,1,21-evolyuciya-elektronnoy-sigarety.html]. The atomizer of the smoke (steam and fogging) of the liquid composition cartridge forms a simulated smoke that enters the lungs. Only if classic SMOKE is a cloud of small particles and resin, vapor electronic cigarettes is a fog is a suspension of tiny droplets of liquid in the steam-air mixture. This mist is heated to the temperature of the smoke regular cigarettes, in order to bring the feeling of a smoker to feel from the usual tobacco use.

The atomizer is put into operation, if it is just delayed. The air-flow sensor connected to the microprocessor, includes a heating element or an ultrasonic generator, [http://megarama.ru/ustrojstvo-elektronnoj-sigarety-i-uxod-za-nej.html].

Cartridge AWIT filled with fibrous mass, for example by padding, holding smoke-generating liquid composition inside the cartridge, dosing him and not giving to spill out onto the atomizer.

Smoke-generating composition includes water, a polyalcohol (glycols, glycerine, flavors, nicotine and other additives. For example, the famous [http://ru.wikipedia.org/wiki/] smoke-generating composition containing:

propylene glycol 55-62%,

glycerin 30-35%,

nicotine 0-36 m is/ml,

flavor 2-4% water;

or smoke-generating composition [http://www.janty.su/safety/]containing:

propylene glycol 52-66%,

food flavor 0-8%,

vanilla extract and 1.5%,

medical nicotine strength:

- there is no fortress 0%

- lowest strength of 0.4% to 0.6%

- the average fortress of 0.9% to 1.1%

- high fortress of 1.3% to 1.6%,

linalool 6%,

glycerol 20%,

Tabanan 1.5%,

2.5-dimethylpyrazine 1%,

2-acetylpyrazine 1%.

Electronic cigarette is an identical replacement for traditional cigarettes. It is assumed that the first electronic cigarette simply replaces the smoker of conventional cigarettes. It is also possible to full exemption from nicotine addiction by gradually lowering the nicotine content to zero.

It should be noted that depending on the device cartridge with smoke-generating composition or device of the electronic cigarette to a greater or lesser extent, possibly escaping smoke-generating composition from the cartridge and enters directly into the mouth of Smoking, which can cause negative feelings. Smoke-generating composition can leak through loose joints electronic cigarettes and dirty as the cigarette, and the fingers of the smoker or the surrounding objects.

It should also be noted that in the preparation of smoke-generating compositions based abderemane is the most basic components, such as propylene glycol or glycerol, with the addition of some aromatic additives does not fully dissolve the latter in the base composition.

Thus, formulations containing 50% propylene glycol, 40% glycerol, 5% isoamylase (flavouring "the Duchess"), or 5% CO 2 extract of tobacco (www.kreovar.ru), the rest is water or ethanol, heterogeneous, which may lead to differences in dosing aromatic components in the formation of smoke while Smoking or requires additional use in smoke-generating composition homogenizing or give a stable emulsion components.

The object of this invention is the smoke (steam, fogging) composition based polypropylenglycol with different number of monomers in the molecule. The tests were carried out using the following polypropylenglycol: PPG, BCPs 725, BCPs 1025. The designation abbreviation BCPs means polypropylenglycol, and the number represents the average molecular weight of polypropyleneglycol. Using polypropylenglycol with greater average molecular weight of BCP 2000, BCPs 2700, BCPs 4000 difficult because they have excessive viscosity and low solubility or are solid.

Table 1 shows the viscosity of the various components used in smoke compositions.

The use of polypropylenglycol in accordance with the present invention allows to reduce the mobility of the smoke-generating compositions and thus reduce the probability of escaping smoke-generating compositions outside of the cartridge or electronic cigarettes, as well as the probability of an undesirable ingress of smoke-generating composition in the mouth of the smoker

This invention allow the us to use any aromatic additives, sparingly soluble in propylene glycol, glycerin, or their mixtures.

The invention is illustrated by, but not limited to the following drawings and examples.

Figure 1 is an electronic device that simulates the tobacco, with the section a-A.

Figure 2 - cartridge electronic device that simulates the tobacco, (EBIT) in context.

An electronic device that simulates the tobacco, consists of a metal shell 1 is placed in her and interconnected electrical contacts of the battery 2, the steam generator 3, is equipped with an led 4, at least one microprocessor 5, and the airflow sensor 6. Executed as a single unit with the shell 1 spray 7 placed in it by the heater 8 and the cartridge 9 containing in smoke-generating composition 10. The heater 8 is placed partially within the cartridge 9 with a minimum clearancewith regard to him to allow evaporation of the smoke-forming composition 10. The shape of the cartridge and the system of holes 11 provide airflow between its walls and the walls of the steam generator 3, the end of which is made of at least one hole 11, and the possibility of electrical contact between the battery 2 and the generator 3, and the ability to charge the battery. The connection of the battery, the generator, is methodid, at least one microprocessor, and the airflow sensor can be performed using heat-resistant wires 12. To ensure air circulation and reliable mounting of the cartridge 9 in the nozzle 7, it is equipped with guide ribs 13 (2), evenly placed along the perimeter of the cartridge.

In the manufacturing process cartridge 9 his camera fill with smoke-forming composition of the present invention, the seal cartridge and insert into the nozzle 7. After connection of the atomizer 7 case 1 EUIT ready to use. After the process of applying the ink cartridge becomes empty, it can be replaced with another cartridge containing a smoke-generating composition.

The device operates as follows, the operation of the device occurs when the retraction of the through hole 11 of the dispenser 7 air flow of not less than 10 ml/s through actuation of the airflow sensor 6. After that, the power is supplied from the battery 3 through the microprocessor 5 to the steam generator 3. In this case the led 4 lights up, and the heater 8 heats, contributing to excessive evaporation of smoke-forming composition 10 of the cartridge 9. Thick vapor, resulting in evaporation, taken up by the air stream and through the opening 11 of the nozzle 7 is transferred into the lungs of the user.

Examples 1-10. The composition of the smoke is forming compositions based polypropylenglycol with the addition of nicotine or without. Mix the components for each smoke-forming compositions 1-8 table 2 in the specified ratio and fill their cartridges electronic cigarette "command opens each scanned page, made under the patent for useful model №103062 U.
