Description

DISPOSABLE ELECTRONIC CIGARETTE

The utility model relates to the field of smoking accessories, namely to electronic cigarettes, and can be used as a device for vaping and helping to combat nicotine addiction.

From the public level of technology in the designated area, it is known that an electronic cigarette (English, e-cigarette) is an electronic device that creates a highly dispersed vapor (aerosol) intended for inhalation (inhalation). It can be used both as a nicotine delivery device (ENDS) and for inhaling flavored vapor (aerosol) without nicotine. Steam is created by evaporation of a specially prepared liquid from the surface of the heating element and looks like tobacco smoke ... The main elements of which are a mouthpiece, a lithium battery and an atomizer that includes a heating element, a cartridge or a reservoir with a special liquid-filler ("Wikipedia The Free Encyclopedia" //Electronic cigarette)//[electronic resource] URL: https://ru. wikipedia. org/wiki/Electronic cigarette (accessed 10/22/2021).

As a consumable material for producing vapor in electronic cigarettes, special liquid is used, or, as it is also called, Illiquid, as well as E-liquid. To deliver nicotine to the user's body, the E-liquid is converted from a liquid state of aggregation due to rapid heating and turns into vapor. When puffed, the user inhales this vapor, which includes nicotine and flavoring. When you exhale, the vapor is very similar to the smoke of a regular cigarette. Liquid for electronic cigarettes consists of a base (a mixture of glycerin and propylene glycol), flavors and nicotine. In this case, the user can independently choose the strength of nicotine and the percentage of the mixture of glycerin and propylene glycol, which, in turn, allows the user to adapt more easily when switching from conventional to electronic cigarettes, and then gradually reduce the concentration of nicotine to give up the bad habit.

Thus, the transition from smoking classic tobacco-burning cigarettes to electronic cigarettes allows the smoker to gradually reduce the degree of nicotine addiction and in the future, strictly following the recommendations and gradually reducing the strength of the liquid, give up the bad habit //[electronic resource] URL: htt s://www.bbc.com/russian/science/2013/09/130909 e-cigarettes patches (accessed 03.12.2021).

Thus, electronic cigarettes are used as an alternative to classic tobacco cigarettes to reduce tobacco-nicotine addiction and, in general, harm to the health of the smoker.

Electronic cigarettes are divided into disposable and reusable according to the frequency of use. Their fundamental difference lies in the fact that reusable electronic cigarettes are equipped, firstly, with a battery, usually lithium, with the possibility of multiple recharging with a socket for connecting to the network, and secondly, with a reservoir of smoking liquid with the possibility of refilling it or replacing the entire cartridge. All this makes it possible to use one electronic cigarette for a long time. Disposable electronic cigarettes, on the other hand, contain a battery, usually alkaline batteries, without the possibility of recharging it, and instead of a replaceable reservoir with smoking liquid, the cartridge contains a storage device (made of cotton and other materials) soaked in this smoking liquid, which is quickly consumed. As a result of the work of one disposable electronic cigarette, as a rule, it lasts a maximum of 500 puffs, that is, for one or two days, depending on intensity of its use (TehnoLev website//What electronic cigarettes are there//[electronic resource] URL: https://tehnolev.ru/tsifrovaya-tehnika/veyp/kakie-elektronnye-sigarety-byvayut.html (accessed 03.12.2021) ; site PIXSELL// Disposable e-cigarette is a real way to quit smoking//[electronic resource] URL: https://www.pixsell.sh/blog/ odnorazovaya-e-sigareta-realnyi-sposob-brosit-kurit (access date 03.12.2021)). As the main advantage of disposable electronic cigarettes, they are distinguished by their lower cost and ease of use compared to reusable counterparts.

The lower cost of disposable electronic cigarettes is primarily due to the simplicity of their design and the use of a cheaper non-rechargeable battery. The design of any disposable electronic cigarette implies the presence of a case, a battery, a means of turning on / off the cigarette (a mechanical button or a puff sensor) and an electronic vaporizer (atomizer) consisting of a heating element (coil), a wick, a steam supply tube and a container with a storage device located in it impregnated with smoking liquid (site RED Vape Nooka11//Disposable electronic cigarettes without nicotine//[electronic resource] URL: htt s://redva e.ru/articles/odnorazovye-elektronnye-sigarety-bez- nikotina/ (accessed 03.12 .2021); website SHERLOCK network of tobacco shops// Disposable electronic cigarettes. /#wd-60373a4d2d6fl (accessed 12/3/2021)).

Patented designs of disposable electronic cigarettes suggest, in order to increase their functionality, the inclusion of various other elements in the design of the device: a vibration motor, a microcontroller, a synchronization unit, a unit for counting and converting energy (foreign patents for inventions No. CN1 10623310A, CN109430947A, priority dates 10/18/2019, 01/11/2019), control module holder, control module with control chip, LED light diffuser (Russian utility model patents No. 121706 (priority date 08.10.2012), No. 122254 (priority date 28.08.2012), No. 124120 (priority date 03.09.2012), chip, screw, pin, metal film, silicon substrate, metal conductive track, aluminum stamp, etc. (Russian patent for invention No. 2747302 (priority date 08.08. 2019).

The main disadvantage of the presented solutions is the complex and, as a result, expensive nature of their design, which eliminates the main advantage of disposable electronic cigarettes over reusable ones - lower cost and ease of use.

As the closest analogue (prototype) of the claimed utility model, based on the totality of essential features, a technical solution was adopted for the Russian utility model patent No. 116018 "DISPOSABLE ELECTRONIC CIGARETE" (priority date 02.22.2012, publication date 05.20.2012, copyright holders Agapov Dmitry Sergeevich (RU) , Gamer Ilya Iosifovich (RU) This solution provides for a disposable electronic cigarette, which contains a tubular-shaped case with a battery compartment, in which a power source in the form of a battery is placed, and an LED located inside the case at one end of the case, covered with a light diffuser, a control microcircuit, connected to the air pressure sensor, as well as a filler with a liquid and a heating unit connected through the specified microcircuit and the air pressure sensor to the power source. another on the sides of which a hole is made in the body wall for communication with the atmosphere and a plug with a central hole is located at a distance from the battery, on which an air duct is fixed, stretched towards the other end of the body, closed by an end plug with a central hole, the cavity in the body between the plugs is filled with a filler with liquid , the end of which is located at a distance from the end cap to communicate the cavity in the housing between the end cap and the filler through the air duct and the hole in the housing wall with the atmosphere. The heating unit is made in the form of a wick placed in the filler with an incandescent thread connected by wires to a power source in the form of a battery.

As a disadvantage of the prototype, one can single out the absence in its design of an element that filters and cools steam. As a result, the steam formed during the operation of the heating unit enters the user through the air duct directly, large hot drops formed during evaporation do not encounter obstacles in their path, which can cause burns for the user and, in general, unpleasant sensations from the process of using the device.

The purpose of this utility model is to eliminate the above disadvantage of the prototype, namely, the provision of pre-filtration and cooling of the hot steam generated as a result of the operation of the heating element before it enters directly to the user.

This goal is achieved by the fact that the design of the proposed disposable electronic cigarette contains a filter, which is located in front of the steam outlet. Accordingly, the technical result of the proposed technical solution "Disposable electronic cigarette" is as follows.

In the proposed utility model, preliminary filtration and cooling of the hot steam formed as a result of the operation of the heating coil before it enters directly to the user is provided. Filtration and cooling are achieved by the fact that the hot drops formed during evaporation as a result of the operation of the heating element meet a filter on their way at the end of the evaporation channel, on which they break into smaller drops and are partially absorbed by the filter material. The result is overall cooling of the steam stream to a user-friendly temperature. And only after that the flow of steam enters through the hole in the mouthpiece directly to the user. Also, the claimed utility model as a whole expands the arsenal of technical solutions for disposable electronic cigarettes.

The technical result is achieved by the fact that a disposable electronic cigarette is characterized by the fact that it contains a housing with an opening in the lower part for air supply, a cartridge consisting of a housing and an internal assembly containing a smoking liquid accumulator with an evaporation channel, a wick, a heating coil, silicone seals on both ends of the internal unit, a mouthpiece with a hole for the outlet of steam, a chassis, a puff sensor with a microphone integrated into it, an LED and an element that controls the operation of the heating coil, a battery, characterized in that at the end of the internal unit of the cartridge, adjacent to the cartridge body from the side of the mouthpiece, is located filter. Also, the case can be made of PCTG plastic. Also, the smoking liquid accumulator may be cotton impregnated with smoking liquid. Also, the evaporation channel can be made of fiberglass. Also the filter can be made of cotton. The claimed technical solution is illustrated by schematic representations of a disposable electronic cigarette in partially (figure 1) and fully disassembled (figures 2, 3) types, explaining the device of the proposed utility model within the framework of the claimed formula, where 1 is a disposable electronic cigarette, 2 is the body of an electronic cigarette, 3 - air inlet in the lower part of the body, 4 - cartridge, 5 - cartridge body, 6 - internal cartridge assembly, 7 - mouthpiece, 8 - steam outlet, 9 - chassis, 10 - puff sensor with integrated microphone, LED and element controlling the operation of the heating coil, 11 - LED, 12 - battery.

To obtain a technical result, the utility model can be implemented in the following preferred manner, which does not exclude other methods of implementation within the framework of the claimed formula of the utility model.

To start the process of smoking (vaping) of smoking liquid, the user touches the mouthpiece (7) of the disposable electronic cigarette (1) with his lips and draws air through the hole (3) in the lower part of the body (2) of the disposable electronic cigarette (1).

Further, the microphone integrated into the puff sensor (10) (not shown in the figures) determines the moment the air is drawn in by the user, namely its pressure drop, and sends a signal to the heating coil control element mounted on a separate microphone board (not shown in the images) and the LED ( eleven). A semiconductor element operating in the control key mode acts as a control element for the operation of the heating coil. As a result, the LED (11) starts to glow, and the semiconductor element, operating in the control key mode, turns on the power supply from the battery (12) to the heating coil (not shown in the images) of the internal cartridge assembly (6). Further, the smoking liquid supplied to the wick from the accumulator (not shown in the images) begins to evaporate as a result of the operation of the hot heating coil, and the resulting hot vapor, together with the flow of air drawn in by the user, is directed through the evaporation channel (not shown in the figures) through the filter (not shown in the figures). shown) and a steam outlet (8) directly to the user. Thus, the hot vapor drops formed during evaporation as a result of the operation of the heating coil meet a filter on their way at the end of the evaporation channel, on which they break into smaller drops and are partially absorbed by the filter material. The result is overall filtration and cooling of the steam stream to a user-friendly temperature. And only after that the flow of steam enters through the hole in the mouthpiece directly to the user. The steam cooled in this way, which does not contain large hot drops, does not burn the lips, mouth, tongue and larynx of the user, makes the process of soaring pleasant and painless.

Silicone seals (not shown in the figures) are made at both ends of the internal assembly of the cartridge (4), which prevent the leakage of smoking liquid from the accumulator both towards the puff sensor (10) and battery (12), and towards the mouthpiece (7) with a hole (8). All elements of the puff sensor (10), the battery (12), the cartridge body (5) and the internal cartridge assembly (6) are attached to each other using the chassis (9).

Also, the body (2) of the disposable electronic cigarette (1) can be made of PCTG plastic (polycyclohexanedimethylene terephthalate modified with glycol). This material is characterized by increased strength, heat resistance and does not contain any harmful compounds. These properties prevent the release from it as a result of heating during operation of the electronic cigarette (1) any harmful substances, making it a safe material to use in an electronic cigarette.

Also, the smoking liquid accumulator may be cotton impregnated with smoking liquid. Also the filter can be made of cotton. Cotton is known to have excellent hygroscopic properties, which makes its use as a smoking liquid storage device preferable.

Also, the evaporation channel can be made of fiberglass. Fiberglass has a rare combination of properties: high tensile and compressive strength, incombustibility, heat resistance, low hygroscopicity, resistance to chemical and biological attack. All this makes the use of fiberglass as the material of the vapor evaporation channel preferable.

Thus, the novelty of the claimed utility model lies in the fact that the presence of a filter in the design of a disposable electronic cigarette achieves preliminary filtration and cooling of the hot vapor formed as a result of the operation of the heating coil before it enters directly to the user. The steam cooled in this way, which does not contain large hot drops, does not burn the lips, mouth, tongue and larynx of the user, makes the process of soaring pleasant and painless.

The applicant is currently producing the proposed utility model.
