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 US 7726320 B2, IPC A24F 1/00, publ. 06/01/2010, the design of an electronic cigarette is known, including a tubular body closed by end inserts in which the central holes are made, and a power source holder in which a longitudinal air channel, a power source, a control device with a control chip are sequentially placed in the body , air pressure sensor, heater and block with liquid.

The disadvantages of the above electronic cigarettes are:

- the complexity of the design, due to the presence of a threaded connection of one of the inserts with the housing, and the presence of the holder of the power source;

- the absence at one end of the cigarette of a light emitter that simulates a burning cigarette;

- the location of the control chip and pressure sensor in the heat-loaded zone near the heater, which negatively affects the reliability of the device.

For the prototype of the claimed utility model, the design of a disposable electronic cigarette is taken, known from patent RU 116018 U1, IPC A24F 47/00, publ. 05/20/2012

A disposable electronic cigarette includes a tube-shaped 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-containing liquid and wrapped around the duct, a plug, a power source, a control module holder and a control module with a control chip, an air pressure sensor and an LED. A distinctive design feature is the presence of a side opening in the housing wall for communication with the atmosphere.

The design of the prototype eliminated the design flaws inherent in the cigarette described in patent US 7726320 B2. However, this design is also not without drawbacks.

The disadvantages of the cigarette prototype are:

- irrational from the point of view of manufacturability, due to the need to make a side hole in the wall of the housing;

- inconvenience of use, due to the need for a strong tightening to operate the pressure sensor, due to significant aerodynamic drag.

The technical results to which the utility model is directed are:

- improving the manufacturability of the design of a disposable electronic cigarette;

- improving the convenience of using a disposable electronic cigarette.

The indicated technical results are achieved in the design of a disposable electronic cigarette, which includes a tubular body, closed on the first side by an end liner with a central hole, and on the second side by a light diffuser, and a heater, wick, filler made of a nonwoven fabric, impregnated with nicotine liquid, power source, control module holder and control module with a control chip, air pressure sensor and LED.

Technical results are achieved in that the light diffuser is provided with at least one channel for the passage of air, the control module holder is made in the form of a glass with an opening for the control module, and at least one through longitudinal hole is made in the holder wall. In this case, in a preferred embodiment, the hole for the control module can be made offset relative to the axis of symmetry of the holder, three through longitudinal holes can be made in the wall of the holder, and the light diffuser can be provided with two channels for the passage of air, made in the form of recesses on the side surface.

The manufacturability of the proposed design of a disposable electronic cigarette is increased due to the refusal to make holes in the wall of the tubular body.

General design rules instruct the designer to avoid arranging holes in plastic parts perpendicular to the direction of the mold connector, since in this case the mold design is complicated and the manufacturing time of the product is increased (the rods forming the holes must be removed before the part is removed from the mold). When making transverse holes by machining, the complexity also increases and, in addition, the percentage of defective products.

The proposed design changes allow you to get holes in the holder and channels in the diffuser during the formation of these parts.

The convenience of using a disposable e-cigarette is to reduce the effort exerted by smokers to puff. The result is achieved by increasing the total cross section of the air channel passing through the cigarette, and the location of the pressure sensor in the air flow between the air channels in the diffuser and the hole in the liner.

The utility model is illustrated by the following drawings.

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 wick 5, heater 6, filler 7 of a nonwoven fabric, impregnated with a nicotine-containing liquid, power supply 8, control module holder 9 and control module 10 with a control chip, air pressure sensor and LED 11, are placed inside the holder 9.

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

The heater 6 is made in the form of a spiral of nichrome wire. The heater wire is wound onto part of the wick 5. The wick 5 is designed for continuous supply of nicotine-containing liquid to the heater 6 through the filler 7.

In the particular case of a disposable electronic cigarette that does not limit the use of this utility model, the wick 5 with a heater 6 is placed in the duct 14, the filler 7 is wrapped around the duct 14, and the cigarette is equipped with a plug 15 that prevents the flow of fluid, in which the hole 16 for air passage from the end insert 2 through the duct 14 and the middle part of the housing 1 to the holder 9 of the control module 10. To place the wick 5 with the heater 6 in the duct 14, in its central part, an incision is made.

It should be noted that other versions of the heater, filler and duct of a disposable electronic cigarette are also possible. For example, a cigarette may be provided with a block inserted into the housing 1 between the end liner 3 and the power source 8, and including a heater, wick, filler, a container with a liquid containing nicotine, and an air duct integrated into the block.

To implement the utility model, the light diffuser 4 is provided with at least one channel 12 for air passage, the holder 9 of the control module 10 is made in the form of a glass with an opening 18 for the control module 10, and at least one through longitudinal is made in the wall of the holder hole 13.

In a preferred embodiment of the utility model, the hole 18 for the control module 10 in the holder 9 is eccentrically offset relative to the axis of symmetry of the holder, the holder 9 is provided with three through longitudinal holes 13 that are made in the wall of the holder from the thickening side, and the diffuser 4 is provided with two channels 12 for passage air formed in the form of recesses on the side surface of the diffuser.

The electronic part of the cigarette includes:

- heater 6;

- a control module 10, in which a printed circuit board 19, an LED 11, an air pressure sensor and a control chip are structurally integrated;

- power source 8 in the form of a battery or accumulator connected by wires 17 to a heater 6 and a control module 10.

The device operates as follows.

The smoker draws air through the opening 3 of the insert 2, the duct 14, the opening 16, the air gap between the power source and the wall of the housing in the middle of the housing, the holes 13 in the holder 9 and the channel for the passage of air 12 in the light diffuser 4.

At the same time, the air pressure inside the housing changes, the sensitive 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 and mixing of the steam with the incoming air from the outside; the resulting air mixture enters the smoker's mouth.

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.
