Description

The utility model relates to the field of satisfying a person’s vital needs, namely to smoking accessories in the form of a flameless electronic cigarette, which are currently classified as “smoking simulators”.

The active ingredient in a cigarette is the alkaloid (i.e. nicotine) of tobacco, which is rapidly absorbed after it enters the pulmonary alveolus with a large number of tar droplets produced during smoking. Once absorbed into the blood, the tobacco alkaloid has an effect on the receptors of the central nervous system, causing a "feeling of intoxication", similar to the feeling that analeptics cause, such as the feeling of dizziness or lightness experienced by the smoker.

Tobacco alkaloid is a low molecular weight alkaloid, which is mainly not harmful to the human body, if only it is consumed in small quantities, and whose half-life in the blood is extremely short. Resin is the main harmful substance in tobacco. Tobacco resin consists of several hundred components, and a number of them cause cancer. In addition, it has been proven that exhaled smoke is even more harmful to non-smokers.

In the consumer market there are many inventions of products designed to replace cigarettes that contain tobacco alkaloid but do not contain tar, a relatively pure tobacco alkaloid, and which include a "quit smoking patch", "rinse containing tobacco alkaloid", "aerosol can high pressure, chewing gum containing tobacco alkaloid, etc. These products are free from harmful tar, however, the tobacco alkaloid contained in them is so poorly absorbed that it cannot effectively achieve a high concentration in the blood. As a result, these products cannot create the sense of satisfaction caused by the tobacco alkaloid, and, moreover, cannot replace the smoking habit, which includes “suction” (“puff”) and exhalation of smoke. Therefore, such products cannot actually be used as smoking cessation products or as substitutes for cigarettes. Some of the problems listed above can be solved with the help of smoking simulators, which received the generalized name of electronic cigarettes by analogy with the shape of real cigarettes.

A flameless electronic cigarette with atomization that does not contain harmful tar is known, which is a single design with a cigarette mouth shape and includes a shell, battery, high-frequency generator, a container with tobacco alkaloid solution, an air flow sensor, a contact sensor, an jet tube for electrothermal gasification ( RU 2336001, A24D 1/00, A24B 15/16, publ. 10.11.2005).

In addition, there is known an electric smoking system including a removable cigarette that contains flavored tobacco material and is electrically heated by electric heating elements in a lighter to emit flavored tobacco smoke or other substances in the form of vapors or aerosol brought to the smoker. A cigarette and a lighter create air currents across the cigarette in the smoking system. Such flows contribute to bringing the aerosol and aromas to the smoker and reduce the condensation of residual vapors and / or aerosol inside the smoking system (RU 2135054, A24F 47/00, published on 08.27.1999).

A device resembling a cigarette is also known, including a battery, a heating element, a signal light and a standard cigarette filter with an axial channel for air passage, the filter and the shell containing the battery being connected by a threaded connection (see, for example, US 4771796, published on September 20, 1988, class A24D 1/00, A24F 1/00, A24F 47/00).

An electronic cigarette is also known, characterized in that it comprises a shell with a battery located therein and electrically connected to each other, an electronic microcontroller equipped with an LED and a device switch, and a nebulizer detachably connected to the shell with an electrothermal element placed therein with a heater and a cartridge, containing material impregnated with a flavored solution, while the heater is partially or partially placed in the cartridge with a gap relative to it that is minimal to ensure the possibility of evaporation of the flavored solution, and the shape of the cartridge allows air to pass between its walls and the walls of the atomizer, at the end of which at least one hole is made, and the connection between the shell and the atomizer is made using a multifunctional connecting element that allows air to pass through and the possibility of electrical contact between the battery and the electrothermal element, as well as the ability to charge the battery (RU 94815, A24F 47/00, A24D 1/00, publ. 08/27/1999).

The disadvantage of this cigarette is its structural complexity, the presence of manual controls, the difficulty of forming air channels and the need to create chargers specifically designed to connect to the battery pack of a cigarette.

This utility model is aimed at achieving a technical result consisting in simplifying the design while ensuring its operational reliability due to the possibility of replacing cigarette units made in the idea of independent modules.

The specified technical result is achieved in that an electronic cigarette, characterized in that it includes a tubular-shaped battery pack with an LED on one end, inside which is a microprocessor connected to a pressure sensor and a battery and contact leads output from the other end of the tubular shape a battery pack, on the inner surface of which a screw thread is made, an atomizer, which is a heating unit and made with a cylindrical body with an external screw a thread for connecting to the battery pack and with reciprocal contact leads, as well as a replaceable cylindrical cartridge with an opening on one end and with a flavored solution based on propylene glycol and / or glycerol with the addition of tobacco alkaloid, while the specified cartridge is made from the other end with cavity for the possibility of dressing the cartridge on the outer surface of the atomizer, a channel is made in the wall of the cartridge for communicating the cavity between the heating element of the atomizer and the inlet to the zmescheniya flavored solution cartridge with an opening at the end of the cartridge, and the outer helical atomizer has a groove for communicating the cavity in the heating element avtomayzera atmosphere.

This utility model is illustrated by drawings, which show particular cases of the device, not covering and, moreover, not limiting the claims of the applicant.

Figure 1 presents a General view of the device Assembly, a longitudinal section;

figure 2 is the same as in figure 1, in a disassembled state.

An electronic cigarette (FIGS. 1 and 2) is a device that simulates cigarette smoking and consists of three modules: an atomizer 2 battery pack 1 and a disposable cartridge 3. The battery pack 1 is made in a tubular shape with LED 4 on one end, inside the housing there is a microprocessor 5 connected to a pressure sensor and a battery 6 and contact leads 7, output from the other end of the tubular shape of the battery unit, on the inner surface of which a screw thread is made 8. The screw thread 8 is used as an element for attaching the battery pack 1 to the mating thread of the battery charging unit 9, which can be performed with the installation socket of the battery pack and (the battery pack is screwed into this socket until the contacts are closed, figure 3). In addition, this screw thread 8 corresponds to a screw thread 10 on the outer surface of the atomizer 2, which allows you to screw the battery pack to the atomizer.

The use of a pressure sensor, the feature of which is the ability to change its physical parameters depending on the pressure of the medium being measured (liquids, gases, steam), made it possible to get away from mechanical and other electronic components to control the cigarette on / off device. In such a sensor, the pressure of the medium being measured is converted into a unified pneumatic, electrical signal or digital code, which allows you to use this sensor as a current chopper or circuit connector without the use of an additional switch.

The atomizer 2 is a heating unit and is made with a cylindrical body with an external screw thread 10 for connection with the battery pack, the atomizer is also made with reciprocal contact leads 11 to provide a contact connection with the contact leads 7 of the battery pack 1. The atomizer has a heating element 12 in the form of a nose. In addition, a groove 13 is made on the outer screw part of the atomizer, forming a channel for communicating the cavity of the atomizer heating element (in front of the heating element in the area of its nozzle) with the atmosphere when the battery pack is screwed onto the atomizer. The atomizer is made with a cylindrical outer surface extending to the shoulder in front of the screw part: a cartridge is put on this cylindrical part of the atomizer body by tightly gripping the atomizer like a ballpoint pen cap.

The disposable cartridge 3 is made in the form of a cylindrical body 14 with an opening 15 at one end and with a flavored solution 16 based on propylene glycol and / or glycerol with the addition of tobacco alkaloid, placed in a special cavity of the body. This cartridge is made from the side of the other end with a cavity for the possibility of putting the cartridge on the outer surface of the atomizer, a channel 17 is made in the cartridge wall for communicating the cavity 18 between the atomizer heating element 12 and the inlet 19 to the placement cavity of the aromatic solution of the cartridge with an opening 15 at the end of the cartridge.

If the flavored solution contains tobacco alkaloid, then when using the device, the smoker maintains the sensation and intake of the usual dose of nicotine, as if he smoked a real cigarette while minimizing the harm to his body due to the absence of tar and other products in his inhaled mixture burning tobacco leaves and cigarette paper, harmful to his health. In addition, the percentage of tobacco alkaloid in the solution may be different. The strength of the inhaled mixture depends on its quantity. The possibility of using a flavored solution with a different percentage of tobacco alkaloid in the device can be used by a smoker in the treatment of nicotine addiction by reducing the use of nicotine over time by replacing the flavored solution used. The composition of the flavored solution may be different. For example, in one case it may include tobacco alkaloid 6%, propylene glycol 85%, glycerin 2%, essence 2%. organic acid 1% and antioxidant 1%. Or, a flavored solution may include tobacco alkaloid 4%, propylene glycol 80%, glycerol 5%, butyl valerate 1%, isoamyl caproate 1%, cinnamyl cinnamate 0.6%, benzyl benzoate 0.4%, methyl octinoate 0.5%, ethyl heptanoate 0.2 %, hexylhexanoate 0.3%, geranyl butyrate 2%, menthol 0.5%, citric acid 0.5%, tobacco essence 4%. Another example of execution can be a flavored solution containing tobacco alkaloid 2%, propylene glycol 90%, citric acid 2.5%, essences 1%, tobacco essences 4.5%. Or, a flavored solution may include tobacco alkaloid 0.1%, propylene glycol 80%, glycerol 5%, ethanol 8%, water 2.9%, essence 1%, essence tobacco 1%, organic acid 2%. In a preferred embodiment, the composition of the flavored solution may include propylene glycol 77.0%, ethyl alcohol 10.0%, malic acid 3.0%, vanillin 2.5%, tetramethylpyrazine 1.5%, menthol 1.0%, acetylpyrazine 1.5 % It is also possible to completely exclude propylene glycol from the composition of the flavored solution, replacing it with glycerin.

The device operates as follows.

The inclusion of an electronic cigarette assembled into a whole of three modular assemblies occurs at the moment of the first inhalation by changing the air pressure in the cigarette cavity: the pressure sensor is triggered and closes near the power supply circuit of the atomizer heating element. After that, power is supplied from the battery to the microprocessor and from it to the LED, flashing or lit indicating the operating modes of the cigarette. For example, when tightening, the LED lights up, the heating element heats up, contributing to the evaporation of the flavored solution from the cartridge. Vapors resulting from evaporation are picked up by the air flow and transferred through the hole through the channel into the user's lungs through the hole 15 of the cartridge.

This utility model is industrially applicable as it can be manufactured using well-known electronic technologies.
