Description

This invention relates to smoke generating compositions based on polypropylene glycol.

Not so long ago, electronic devices for simulating smoking were invented (EUIT) (RU 2336002, publ. 10/20/2008, No. 29, No. 103062U, publ. 03/27/2011), generating steam or fog, which may not contain nicotine even if inhaled evoke the taste of real tobacco smoke. EUITs are manufactured in the form of cigarettes, cigars, smoking pipes, etc., and are essentially an inhaler. The design of the EUIT is based on a cartridge containing a smoke-generating (vapor- or fog-forming) liquid composition and a steam- or fog-generator called an “atomizer” [US 2011/0011396 A1 (2011), US 783241082 (2010)].

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

Some models of electronic cigarettes have disposable vaporizers. At the same time, they are included in the composition of the cartridges, thus, when the cartridge is changed, the heating element also changes. This design (cartridge + atomizer) is called a cartomizer [http://www.electro-dym.ru/. http://www.cybersmoke.ru/index.php?category.].

Atomizers include an evaporator (heating element, for example, a nichrome spiral) or an ultrasonic atomizer [http://www.ecig-news.ru/history/evolution-means/print:page,1,21-evolyuciya-elektronnoy-sigarety .html]. The atomizer from the smoke-generating (vapor- and fog-forming) liquid composition of the cartridge forms an imitation of smoke that enters the lungs. Only if the classic SMOKE is a cloud of fine solid particles and tar, then the vapor of an electronic cigarette is a fog - a suspension of the smallest droplets of liquid in a vapor-air mixture. This fog is heated to the smoke temperature of a regular cigarette in order to bring the smoker's sensations as close as possible to those of ordinary smoking.

The atomizer comes into operation if you just drag on. The air flow sensor connected to the microprocessor includes a heating element or an ultrasound generator, [http://megarama.ru/ustrojstvo-elektronnoj-sigarety-i-uxod-za-nej.html].

The EUIT cartridge is filled with pulp, for example, synthetic winterizer, which holds the smoke-forming liquid composition inside the cartridge, dosing it and preventing it from pouring onto the atomizer.

The smoke-generating composition includes water, polyalcohols (glycols, glycerins), flavorings, nicotine and other additives. For example, the known [http://ru.wikipedia.org/wiki/] smoke-forming composition containing:

propylene glycol 55-62%,

glycerin 30-35%,

nicotine 0-36 mg / ml,

flavoring 2-4% and water;

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

propylene glycol 52-66%,

food flavoring 0-8%,

vanilla extract 1.5%

medical nicotine of various strengths:

- no strength 0%

- low strength 0.4% to 0.6%

- average strength 0.9% to 1.1%

- high strength of 1.3% to 1.6%,

linalool 6%

glycerin 20%,

Tabanon 1.5%

2,5-dimethylpyrazine 1%,

2-acetylpyrazine 1%.

An electronic cigarette is an identical replacement for traditional cigarettes. It is assumed that at first the electronic cigarette simply replaces the smoker's regular cigarettes. Further, a complete release from nicotine addiction is possible by gradually reducing the nicotine content to zero.

It should be noted that, depending on the device of the cartridge with the smoke-generating composition or the device of the electronic cigarette, it is more or less possible for the smoke-forming composition to leak out of the cartridge and enter it directly into the smoker's mouth, which can cause negative feelings. The smoke-forming composition can seep through the loose seals of the electronic cigarette and stain both the cigarette itself and the fingers of the smoker or objects surrounding it.

It should also be noted that in the preparation of smoke-forming compositions based on commonly used basic components, such as propylene glycol or glycerin, with the addition of certain aromatic additives, the latter do not completely dissolve in the composition base.

Thus, compositions containing 50% propylene glycol, 40% glycerol, 5% isoamyl acetate (Duchess flavor) or 5% CO-2 tobacco extract (www.kreovar.ru), the rest of the water or ethanol, are heterogeneous, which can lead to heterogeneity dosing aromatic components during the formation of smoke during smoking or requires additional use in the smoke-forming composition of homogenizing or stable emulsion components.

The subject of this invention is a smoke generating (vapor, fogging) composition based on polypropylene glycols with various amounts of monomer in the molecule. The tests were carried out using the following polypropylene glycols: PPG425, PPG 725, PPG 1025. In the designation, the abbreviation PPG means polypropylene glycol, and the number corresponds to the average molecular weight of polypropylene glycol. The use of polypropylene glycols with a higher average molecular weight of PPG 2000, PPG 2700, PPG 4000 is difficult, because they have excessive viscosity and low solubility or are solid.

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

The use of polypropylene glycol in accordance with the present invention allows to reduce the mobility of smoke-forming compositions and thereby reduce the likelihood of smoke-forming compounds leaking out of the cartridge or electronic cigarette, as well as the likelihood of an undesirable smoke-forming composition entering the smoker's mouth

The present invention allows the use of any aromatic additives that are sparingly soluble in propylene glycol, glycerin, or mixtures thereof.

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

Figure 1 - electronic device that simulates smoking, with a cut along aa.

Figure 2 - cartridge electronic device that simulates smoking, (EUIT) in the context.

An electronic device simulating smoking consists of a metal shell 1 with an accumulator 2 placed in it and interconnected by electrical contacts, a steam generator 3, equipped with an LED 4, at least one microprocessor 5, and an air flow sensor 6. Made as a whole a shell 1 a sprayer 7 with a heater 8 and a cartridge 9 located therein, containing a smoke-generating composition 10 inside. The heater 8 is partially placed in the cartridge 9 with a minimum clearance relative to it, to allow evaporation of the smoke-generating composition 10. The shape of the cartridge and the system of holes 11 allow air to flow between its walls and the walls of the steam generator 3, at the end of which at least one hole 11 is made, and electrical contact between the battery 2 and steam generator 3, as well as the ability to charge the battery. The connection of the battery, steam generator, LED, at least one microprocessor, and the air flow sensor can be made using heat-resistant wires 12. To ensure air circulation and reliable fastening of the cartridge 9 in the atomizer 7, it is equipped with guide ribs 13 (figure 2) evenly spaced around the perimeter of the cartridge.

In the process of manufacturing the cartridge 9, its chamber is filled with the smoke-generating composition of the present invention, the cartridge is sealed and inserted into the atomizer 7. After the atomizer 7 is connected to the housing 1, the EMF is ready for use. After the cartridge becomes empty during use, it can be replaced with another cartridge containing the smoke-generating composition.

The device operates as follows, the device is triggered when the air stream 6 is pulled through the hole 11 of the atomizer 7 by means of an air flow sensor 6. After this, the power is supplied from the battery 3 through the microprocessor 5 to the steam generator 3. At the same time, the LED 4 lights up and the heater 8 glows, contributing to the abundant evaporation of the smoke-generating composition 10 from the cartridge 9. The thick vapor resulting from the evaporation is picked up by the air flow and through the opening 11 of the races ylitelya 7 transported into the lungs of the user.
