Description

An electronic cigarette with a visible burning line

technical field

The invention relates to the technical field of electronic cigarette products, in particular to an electronic cigarette with a visible combustion line.

Background technique

With the diversified development of the e-cigarette industry, various e-cigarette products continue to emerge, and their distinctive appearance designs meet people's consumption needs in different gears. In order to meet the ever-growing material and cultural needs, electronic cigarette development designers have made unremitting efforts to explore electronic cigarettes with new functions.

The counter starts counting after signal conversion according to the number of suction ports, and then controls the corresponding indicator light to light up. The DC working voltage of the battery drives the central controller and the counter to work, and provides energy for the normal operation of the atomizer.

The electronic cigarette of the present invention can sequentially trigger corresponding indicator lights according to the amount of puff, not only can simulate the effect of continuous shortening of the effective length of cigarettes when smoking traditional cigarettes, but also can judge that the user has smoked according to the corresponding lit indicator lights. The suction volume, and give a reminder when the user reaches the preset suction volume. Under the premise of not significantly increasing the volume of electronic cigarettes, smokers can get a feeling closer to the combustion process of real cigarettes.

Detailed ways

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

As shown in Figure 1, the electronic cigarette with visible combustion line involved in the present invention includes: end cap 1, tobacco rod casing 2, battery 4, control circuit board 5, cartridge 7, heating unit 8, oil storage cotton 9. Oil guide tube 10, suction nozzle 11; battery, control circuit board, cartridge, heating unit, oil storage cotton, oil guide tube, and suction nozzle are all placed in the shell of the tobacco rod, and the two ends of the shell of the smoke rod are end caps and suction pipes. The nozzle, the control circuit board is set in the middle of the shell of the tobacco rod, and is connected to the battery. The other end of the battery is connected to the end cover, and the other side of the control circuit board is provided with an oil guide tube. A heating unit is installed in the oil guide tube. The periphery of the heating unit is an oil storage cotton , the outer periphery of the oil storage cotton is a pod, the oil guide tube is connected and fixed with the casing of the device through the riveting part 6, the oil guide tube is connected to the end cover, and an indicator light 3 is arranged on the casing of the device.

The heating unit, oil storage cotton, and oil guide tube constitute the atomizer assembly, which uses electric heating to atomize the smoke liquid, and the battery provides energy for the atomizer to work; the control circuit board controls the atomizer to work during suction, and according to the degree of suction 1. The liquid consumption in the pod controls the work of the indicator light at a specific position (intuitively reflecting the consumption of cigarettes and liquid); the silicone nozzle communicates with the airflow channel in the atomizer assembly; a battery is formed inside the pod shell And the cavity of the control circuit board.

In the electronic cigarette, the shell of the tobacco rod section is made of transparent material, which is convenient for light scattering of the indicator light.

The number of indicator lights or light emitting diodes is 8-10; a plurality of light emitting diodes or small indicator lights and a driving circuit form an output display. the

The indicator lights are light-emitting diodes or small indicator lights, and the display colors of the indicator lights can be the same or different, and the indicator lights of different colors can be arranged regularly to enhance the degree of differentiation.

The indicator light can be arranged directly on the control circuit board when light-emitting diodes are used, and can be arranged in the casing of the cigarette rod or the cavity of the casing of the cigarette rod and the battery when a small indicator light is used;

As shown in FIG. 2 , the control circuit includes a central processing unit MCU, a suction sensor directly connected to the MCU, a heating wire driving unit, a counter and a decoder, and an indicator light or a light-emitting diode connected to an output end of the decoder.

When the electronic cigarette starts to work, the airflow sensor collects the suction signal and sends it to the central processing unit MCU. The MCU controls the counter to work. The counter will start counting after the signal is converted according to the number of suction ports. Then the central processing unit MCU processes the signal and controls the corresponding indicator light. glow. The DC working voltage of the battery drives the central controller and the counter to work, and provides energy for the normal work of the battery.

When a person smokes an electronic cigarette, the suction sensor generates a signal; the counter accumulates and registers the suction signal. In this circuit, a 12-bit asynchronous binary counter of CD4040 is used, with 8 indicator lights, and the number of cigarettes that can be smoked. Up to 200 ports as an example, the corresponding 74LSl38 decoder can be selected. 74LSl38 is a 3-8-wire decoder, with 3 address input terminals A2, A1, A0 and 3 strobe terminals S1, S2, S3 and 8 decoder output terminals Y0-Y1, the 8 output terminals are respectively Control 8 groups of indicator lights 3 corresponding to the positions. The indicator light at the farthest end of the cigarette holder flickers in the first 25 puffs; the second light flickers through signal processing on the counter during the 26th to 50th puffs; and so on. The central processing unit adopts the microprocessor of SLH89F5116. This type of MCU is an 8-bit program-protected MCU with superior performance, built-in 256-byte RAM and 2 16-bit timer/counters, 1 UART, external interrupt INT0 and INT1, fully compatible with 8051 instruction level, and can execute programs accurately Instructions to control the normal work of electronic cigarettes.

The 12-bit asynchronous binary counter of CD4040 has only two input terminals, namely the clock input terminal CP and the clear terminal CR. The output terminals are Q1-Q12. When the clearing terminal CR is high level, the counter output is all cleared; when the zero clearing terminal CR is low level, the counting is completed on the falling edge of the CP pulse.
