Description

Electronic cigarette maker

[Technical field]

The utility model relates to a smoking implement, in particular to an electronic smoking device.

[Background technique]

Tobacco smoke contains at least three chemicals: tar, nicotine, and carbon monoxide. Tar is a mixture of several substances that condense into a sticky carcinogen in the lungs. Nicotine has a boiling point of 247 ° C. Nicotine is an addictive drug that is absorbed by the lungs and acts primarily on the nervous system. Carbon monoxide is produced by incomplete combustion of cut tobacco, which can reduce the ability of red blood cells to transport oxygen to the whole body, which is extremely harmful to the human body.

In the smoking process, except for the outer part of the cigarette, it is basically burned under the condition of insufficient oxygen supply. The carcinogens such as tobacco tar are mostly produced at 500-900 °C, and the smoke tar and carbon monoxide generated during smoking are accompanied by smoke. Flow into the respiratory tract of smokers, causing harm to smokers.

[Summary of the Invention]

The technical problem to be solved by the utility model is to provide an electronic smoking device which does not generate smoke tar and carbon monoxide during smoking.

In order to solve the above technical problem, the technical solution adopted by the utility model is an electronic cigarette maker comprising a power source, a heating rod, a power supply box and a heating circuit. The front end of the heating rod includes a pointed end, and the rear end is fixed on the power supply box; the heating circuit includes The controller and the at least one heating unit comprise an electronic switch and an electric heating element; the electric heating element is arranged in the inner cavity of the heating rod, the electric heating element is connected to the power source through the electronic switch, and the control end of the electronic switch is connected to the control signal output end of the controller.

In the above electronic cigarette smoker, the front end of the power supply box includes a cigarette case, and the cigarette case is wrapped around the heating rod surface.

In the above electronic cigarette maker, the electric heating element is a positive temperature coefficient thermistor.

The electronic smoking device described above includes a plurality of the heating units, and the electric heating elements of the plurality of heating units are arranged along the axial direction of the heating rod, and the control end of each heating unit electronic switch is connected to a control signal output end of the controller. .

The electronic smoking device described above includes a circuit board, a controller and an electronic switch disposed on the circuit board, and the circuit board is disposed in the power supply box.

The electronic cigarette smoker of the utility model uses an electric heating rod to heat the tobacco of the cigarette, the smoker can only suck the nicotine generated by the heating of the tobacco, the heating rod does not produce an open flame, and the heated tobacco does not generate the smoke tar and the carbon monoxide, Reduce the harm of tobacco to smokers. .

[Description of the Drawings]

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a front elevational view of an electronic smoking device in accordance with an embodiment of the present invention.

Figure 2 is a cross-sectional view taken along line A of Figure 1.

3 is a circuit block diagram of an electronic smoking device in accordance with an embodiment of the present invention.

[detailed description]

The structure of the electronic cigarette smoker of the present invention is as shown in FIG. 1 to FIG. 3, and includes a plurality of button batteries 5, a heating rod 1, a battery box 2 and a heating circuit.

The heating rod 1 has a hollow structure with a pointed end 101 at the front end and a rear end fixed to the battery case 2. The front end of the battery case 2 has a cigarette case 201 which surrounds the outside of the heating rod 1. The diameter of the inner hole of the cigarette case 201 is slightly larger than the diameter of the cigarette 10.

The heating circuit includes a circuit board 4, an MCU, a power switch 6 and 4 heating units, each heating list The element includes an electronic switch and an electric heating element, and the electric heating element is a positive temperature coefficient thermistor 3.

4 positive temperature coefficient thermistors 3 are arranged in the inner cavity of the heating rod 1, arranged along the axial direction of the heating rod 1, and the positive temperature coefficient thermistor 3 is connected to the battery 5 through an electronic switch, and the control end of each heating unit electronic switch Connect to a control signal output of the MCU.

The circuit board 4 is a flexible circuit board on which the MCU and the electronic switch are disposed, the button battery 5 and the circuit board 4 are disposed in the battery case 2, and the power switch 6 is disposed on the outer wall of the battery case 2.

In the electronic smoker of the above embodiment, the cigarette 10 is inserted into the tubular cigarette case 201, the filter 1001 faces outward, the heating rod 1 is inserted into the tobacco 1002 of the cigarette, and then the heating is started by the power switch 6. The circuit and the microcontroller (MCU) start the electric heating element one by one from left to right. The working temperature of the electric heating element is constant at about 300 ° C, which is less than the lowest temperature of 500 ° C of tar. At this time, only nicotine is volatilized, and the smoker can pump it. Nicotine aerosol, because there is no open flame, no carbon monoxide, smokers will not smoke tar and carbon monoxide. Each electric heating element works for a period of time, after the nicotine volatilization corresponding to the cigarette segment of the heating section is completed, the next electric heating element on the right side is started, and all the heating sections are stopped after the work is completed, waiting to replace the cigarette. When smoking, the smoker The cigarette case 201 can be held by hand.

The electronic cigarette smoker of the above embodiment uses an electric heater to heat the tobacco of the cigarette, the smoker can only suck the nicotine generated by the heating of the tobacco, the electric heater does not produce an open flame, and the heated tobacco does not generate the smoke tar. And carbon monoxide can reduce the harm of tobacco to smokers.
