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 disposable cigarette - a simulator of smoking.

In an electronic cigarette, unlike a regular cigarette, there is no burning process. Due to this, excluded the release of carcinogens, tar, ammonia, benzene and other harmful substances that are inevitably present when burning cigarette paper and tobacco.

From patent RU 116018U1, IPC A24F 47/00, publ. 05/20/2012, the design of a disposable electronic cigarette is known. The cigarette includes a tubular body, closed on one side by an end liner with a central hole, and on the other hand, by a light diffuser, and an air duct made in the form of a tube placed in the housing, a heater placed on the air duct, a non-woven fabric filler impregnated with nicotine liquid and wrapped around the duct, plug, power source, control module holder and control module with a control chip, air pressure sensor and LED.

The drawback of the design of such a cigarette is the presence of a filler made of a non-woven fabric, as a result of which the useful volume occupied by the nicotine-containing liquid and the life of the electronic cigarette are significantly reduced.

The prototype of the claimed utility model is the design of a disposable electronic cigarette, known from the Chinese Utility Model Patent CN 201781984, IPC A24F 47/00, publ. 04/06/2011

The cigarette includes a tubular body enclosed on one side by an end insert with a central hole, and a power source, a heater, and a container containing nicotine-containing liquid placed in the body. The container has the shape of a cylinder with a flat section for the passage of the air mixture from the heater chamber to the central hole of the end liner, and is closed by the first lid, in which the wick is inserted. The container is also closed with a second lid; the space between the covers forms a heater chamber in communication with the central hole of the end insert. In the air chamber there is a heater spiral wound around the end of the wick.

The advantage of the design of the prototype is the absence in the container for the nicotine-containing liquid of the filler from the non-woven fabric, due to which the cigarette has an increased useful volume occupied by the nicotine-containing liquid and an increased electronic cigarette life.

The disadvantage of the prototype is the complexity of the design and the associated high complexity of manufacturing, which is due to the need to immerse the ends of the wick through a narrow hole in the first lid of the container in a nicotine-containing liquid.

The technical results that the utility model is aimed at are simplifying the design and reducing the complexity of manufacturing a disposable electronic cigarette.

These technical results are achieved in the design of a disposable electronic cigarette, which includes at least a tubular body and a control module with a pressure sensor and a control microcircuit, a power source, a container containing nicotine liquid, closed with the first and second caps, formed between the covers of the heater chamber, and the heater located in the chamber, with an incandescent thread wound on the wick,

Technical results are achieved in that at least two small-diameter holes are made in the first lid of the container, the cigarette is equipped with an absorbent pad located in the heater chamber and covering the openings mentioned above, while the ends of the wick are in contact with the surface of the absorbent pad.

Reducing the complexity of manufacturing a disposable electronic cigarette is achieved by refusing to perform the laborious operation of placing the wick in the opening of the first lid of the container.

Simplification of the design is achieved by placing the ends of the wick on the surface of the absorbent pad, without introducing them into the opening of the first container lid.

The utility model is illustrated by the following drawings. Figure 1 presents a disposable electronic cigarette in longitudinal section;

The utility model can be successfully implemented in the design of a disposable electronic cigarette, see Figure 1, which includes a tubular body 1 closed on the first side by an end liner 2 with a central hole 3, and on the second side by a light diffuser 4, and placed in case 1 control module 5 with an LED 6, a pressure sensor and a control microcircuit (the sensor and microcircuit are not shown in Fig. not shown) installed in the holder 7, a power supply 8, a heater 9, the filament of which is wound on the wick 17, the container 10 containing Nicotine liquid, closed first cover 12 and second cover 13.

The case 1 of a disposable electronic cigarette from the side of the end liner 2 during storage is closed with a hygienic cap (not shown in Fig.).

The filament of the heater 9 is made of nichrome wire. The wire is wound on the wick 17. The wick 17 is designed for continuous supply to the heater 9 containing nicotine liquid from the container 10.

The container 10 is made in the form of a cylinder with a flat wall 14.

The container is closed by the first lid 12 and the second lid 13.

A central hole 18 is formed in the second lid.

In the space between the covers 12, 13, a heater chamber 9 is formed.

Each of the covers 12, 13 is provided with a side opening 20, 21 for passing the air mixture through the heater chamber in the direction from the hole 18 through the side openings 20, 21 to the hole 3 of the end insert.

To implement the utility model, the following changes are made in the design of the cigarette.

In the first lid 12 of the container 10 perform (see Figure 2), at least two holes 15 of small diameter for supplying nicotine-containing liquid. The holes are closed on the outside of the cover 12 with an absorbent pad 11. The ends of the wick 17 are brought into contact with the surface of the pad 11.

Through the ends of the wick 17 and the absorbent pad 11, a portion of the nicotine-containing liquid constantly wets the wick. The small size of the holes 15 and the presence of an absorbent pad 11 do not allow liquid to pour out of the container 10.

To facilitate the assembly of the cigarette, the lids 12, 13 can be equipped with means for ensuring the mutual orientation of the lids, in which the cutouts 20 and 21 are located opposite each other. For example, a cutout 16 can be made on the side surface of the first cover 12, and a protrusion interacting with the cutout 16 can be made on the side surface of the second cover (not shown in FIG.).

Thanks to the proposed changes in the design of a disposable electronic cigarette, the need to immerse the ends of the wick inside the container through the openings in the lid 12 is eliminated, and the manufacture and assembly of the electronic cigarette is most simple and quick.

The electronic part of the cigarette includes:

- heater 9;

- a control unit 5 in which a printed circuit board (not shown in FIG.) is structurally integrated, an LED 6, an air pressure sensor and a control chip (not shown in FIG.);

- power source 8 in the form of a battery or accumulator connected by wires 19 to a heater 9 and a control module 5.

The device operates as follows.

The smoker draws air through the opening 3 of the insert 2. In this case, the air mixture passes through the air passage channels made in the diffuser 4 of the light (not shown in FIG.), The holes in the holder 7 of the control unit 5 (not shown in FIG.), The gap between the power source 8 and the wall of the housing 1 in the middle of the housing, the central hole 18 in the second lid 13 of the container, the heater chamber, the openings 20, 21 in the lids 12, 13 and the gap between the walls of the cigarette body and the wall 14 of the container, and enters through the hole 3 in smoker's mouth.

The passage of the air mixture is accompanied by a change in air pressure inside the cigarette case, the sensing element of the air pressure sensor responds to pressure changes and the corresponding signal from the air pressure sensor is fed to the input of the control microcircuit, which closes the heater power circuit, and also supplies voltage to the LED that operates in the glow mode when performing a puff. When voltage is applied to the heater, the latter heats up and transfers heat to the wick soaked in nicotine-containing liquid. Heating the wick leads to evaporation of the liquid in the heater chamber and mixing of the steam with the incoming air from the outside.

At the end of the puff, the signal of the air pressure sensor changes, the control chip breaks the voltage supply circuit from the power source to the heater and the LED.

A disposable electronic cigarette can be used before the discharge of the power source (battery or accumulator) or the consumption of liquid in the filler. Due to the absence of filler in the container, the volume of the container is used to the fullest and the resource of the electronic cigarette increases.
