Description

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 prior art in the designated area, it is known that an electronic cigarette (English e-cigarette ) is an electronic device that creates 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 12/20/2021).

As a consumable for producing vapor in electronic cigarettes, special liquid is used, or, as it is also called, E-liquid, 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. At the same time, 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 reducing 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 (BBCNEWS Russian service website//Scientists: electronic cigarettes help quit smoke//[electronic resource] URL: https://www.bbc.com/russian/science/2013/09/130909_e-cigarettes_patches (accessed 12/20/2021).

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 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 operation of one disposable electronic cigarette, as a rule, it is enough for a maximum of 500 puffs, that is, for one or two days, depending on the 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); PIXSELL website// Disposable e-cigarette is a real way to quit smoking//[electronic resource] URL: https:/ /www.pixsell.ru/blog/odnorazovaya-e-sigareta-realnyj-sposob-brosit-kurit (accessed 12/21/2021)). 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 Hookah//Disposable electronic cigarettes without nicotine//[electronic resource] URL: https://redvape.ru/articles/odnorazovye-elektronnye-sigarety-bez-nikotina/ (accessed 12/21/2021 ); website SHERLOCK network of tobacco stores// Disposable electronic cigarettes. -60373a4d2d6f1 (accessed 12/21/2021)).

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. 2019), control module holder, control module with a control chip, light diffuser from an LED (Russian utility model patents No. 121706 (priority date 08.10.2012), No. 122254 (priority date 08.28.2012), No. 124120 ( priority date 09/03/2012), 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 drawback of the presented solutions is the lack of methods for cooling the hot vapor coming along with the flow of air drawn in by the user of an electronic cigarette. The fact is that the hot steam formed as a result of the operation of the electronic evaporator (atomizer) enters, together with the flow of drawn air, directly to the user. At the same time, this steam also contains large hot drops of the smoking mixture. Getting on the lips, palate, tongue, throat, these drops can cause irritation and even burns, which makes the vaping process unpleasant and painful for the user.

To solve this problem, the state of the art currently provides for various technical solutions for cooling the air flow entering the smoker containing vapors of the smoking mixture, including using a heat exchanger that cools the air before it is drawn through the mouthpiece (Russian patent for invention No. 2647773 ), creating, by means of an additional inlet, an additional air flow that does not pass through the heating element and mixes with the air flow containing hot steam to cool it (Russian patent for invention No. 2643422), the use of a special insert with an adsorbent located in the path of the air flow (foreign patent for utility model No. CN112568490A), creating a vortex effect of hot steam air flow by means of several ventilation holes along the diameter of the cigarette body (Russian patent for invention No. 2616556) and other solutions.

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 patent for invention No. 2627002 "ELECTRONIC SMOKING PRODUCT" (priority date 31.01.2013, publication date 02.08.2017, Patent holder OLTRIA CLIENT SERVICES INC. (USA) )). This solution provides an electronic smoking article that contains a replaceable cartridge (or first section) and a reusable device (or second section), which are interconnected. In general, the second section includes a puff sensor responsive to air being sucked into the second section through an inlet located near the free end or tip of the cigarette, a battery, and a control circuit. The disposable first section contains a liquid supply area and a heater that converts the liquid sucked up by the wick from the area into an aerosol. The first section contains an outer tube (or housing) extended in the longitudinal direction, and an inner tube (or chimney) located coaxially inside the outer tube. A sealing outlet gasket is inserted into the end of the inner tube located on the inlet side. Preferably, the forward part of the downstream sealing gasket is inserted into the end of the inner tube. The space formed between the inlet gasket, the outlet gasket, the outer tube and the inner tube delimits the liquid supply area. Preferably, the liquid storage material is a fibrous material containing cotton, polyethylene, polyester, viscose, or a combination thereof. The mouthpiece insert contains an aerosol mechanical converter insert located downstream of the gasket and containing three elongated outlets extending circumferentially around the perimeter of the open end surface of the aerosol mechanical converter insert, and a front surface located upstream of the open end surface and at a distance from the specified central holes, while the front surface and the specified central hole are located so that at least part of the steam flow, passing through the specified central hole, hits the front surface and changes its characteristic. Alternatively, the face of the insert may be porous to allow collection of particles by adsorption and/or absorption, and instead or in addition may be concave with or against the direction of flow in order to control the performance of the mechanical aerosol transducer. The technical result is to reduce irritation of the throat.

As a disadvantage of the prototype, one can single out the insufficient effectiveness of the implementation of the claimed technical result - reducing throat irritation. The design of the prototype provides for breaking the air flow with hot steam on the surface of the insert and thereby breaking relatively large aerosol droplets, as well as absorbing the aerosol droplets by the adsorbing surface of the insert. However, the flow of air with hot steam passes through the inner tube (chimney) and all openings of the insert directly and at speed directly to the user. That is, the actual cooling of the air flow is not carried out sufficiently, the air flow with steam simply does not have time to cool, which can lead to the inflow of insufficiently cooled, hot air flow with steam to the user and thereby cause him discomfort during the soaring process.

The purpose of this utility model is to eliminate the above drawback of the prototype, namely, significant cooling of the air flow with steam resulting from the operation of the device to a temperature comfortable for the user before it enters directly to the user.

This goal is achieved by the fact that the design of the proposed disposable electronic cigarette provides for the presence of a filter, two holes for the release of steam in the mouthpiece and the implementation of a silicone seal adjacent to the filter in the form of a conical inclined plane.

Accordingly, the technical result of the proposed technical solution "Disposable electronic cigarette" is as follows.

In the proposed utility model, preliminary significant cooling of the steam-air mixture flow formed as a result of the operation of the device to a temperature comfortable for the user is provided before it enters directly to the user. At the same time, this cooling is achieved by the fact that the hot steam formed as a result of the operation of the hot heating coil together with the air flow due to the presence of two holes in the mouthpiece, the inner surface of which acts as a separator between them by the air flow, and the implementation of a silicone seal adjacent to the filter, in the form conical inclined plane, is divided into several streams of a vapor-air mixture, which swirl in several circular orbits, as a result of which, due to centrifugal forces, large drops of hot vapor in the air streams are thrown onto the filter and absorbed by it, which, together with the mixing of streams with air and other streams leads to a decrease in the temperature of the air stream with steam entering directly to the user to a temperature comfortable for 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 assembly, a mouthpiece, 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 a filter is located at the end of the internal cartridge assembly adjacent to the cartridge body from the side of the mouthpiece, the mouthpiece is made two holes for steam outlet, and the silicone seal adjacent to the filter is made in the form of a conical inclined plane. Also, the body 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 images of a disposable electronic cigarette in a partially (figure 1) and completely disassembled (figures 2, 3) views, as well as a schematic representation of the design of the cartridge part and the mouthpiece in a section (figure 4), explaining the device of the proposed utility model within the framework of the claimed formulas, where 1 is a disposable electronic cigarette, 2 is an electronic cigarette body, 3 is an air supply hole in the lower part of the body, 4 is a cartridge, 5 is a cartridge body, 6 is an internal cartridge assembly, 7 is a mouthpiece, 8 is an exit hole pair, 9 - chassis, 10 - puff sensor with a microphone integrated into it, an LED and an element that controls the operation of the heating coil, 11 - an LED, 12 - a battery, 13 - an evaporation channel, 14 - a filter, 15 - a silicone seal adjacent to the filter.

To obtain a technical result, the utility model can be implemented in the following preferred way, which does not exclude other ways 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 of air inhalation by the user, namely the 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 (11 ). 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 (13) directly to the inner surface of the mouthpiece (7), located along the flow path between the steam outlets (8). As a result, the air flow with hot steam breaks up on this area of the inner surface of the mouthpiece (7), which thus acts as a specially formed protrusion and a kind of flow divider. Further, the separated flows of the steam-air mixture are directed to the silicone seal (15) adjacent to the filter, made in the form of a conical inclined plane, repelled from it, as a result of which the steam-air mixture flow swirls and, due to the initially given speed, the movement of air flows in several circular orbits is achieved. . As a result, due to the action of centrifugal forces in these orbits, large drops of the vapor-air mixture are thrown onto the filter (14) and absorbed by it. Then, cooled down due to mixing with air, other flows and absorption of large hot drops of steam, the flows of the steam-air mixture through the holes (8) come directly to the user. As a result, effective mixing of the air flow with steam and significant cooling of the obtained steam-air mixture to a temperature comfortable for the user is achieved. At the same time, there are no large hot drops in this stream that could burn the lips, palate, tongue, throat of the user. Thus, the proposed design of a disposable electronic cigarette makes the vaping process pleasant and painless.

Silicone seals made at both ends of the inner cartridge assembly (4) (only silicone seal 15 adjacent to the filter is shown) prevent the flow of smoking liquid from the accumulator both towards the puff sensor (10) and accumulator (12) and towards the mouthpiece ( 7) with 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 of any harmful substances from it as a result of heating during the operation of an electronic cigarette (1), which makes it a safe material for use in an electronic cigarette.

Also, the smoking liquid accumulator may be cotton impregnated with smoking liquid. Also, the filter (14) 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 (13) 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, two holes for the outlet of the vapor-air mixture in the mouthpiece and the implementation of a silicone seal adjacent to the filter in the form of a conical inclined plane achieves preliminary significant cooling of the vapor-air mixture flow to user-comfortable temperature before it is delivered directly to the user. The steam-air mixture cooled in this way, which does not contain large hot drops, not lips, palate, tongue, throat of the user, makes the process of soaring pleasant and painless.

The applicant is currently carrying out industrial production of the proposed utility model.
