Description

Technical Field

[0001] This invention belongs to the field of electronic cigarette sensor technology, and specifically relates to a low-voltage sensor control method and device. Background Technology

[0002] Based on the purpose and principle of low-pressure sensors in e-cigarettes, various situations may arise when sensing the inhalation action within the e-cigarette using a low-pressure sensor, but not limited to the one mentioned below. When a user inhales the e-cigarette, the pressure causes the diaphragm to deform, resulting in changes in the potential and capacitance of the electrode plates, thereby controlling the heating of the e-liquid in the e-cigarette to produce vapor.

[0003] The existing low-pressure sensors have a relatively simple function. They can only generate smoke after sensing the suction action. Although they can be used normally when people inhale them, the smoke will not automatically stop when people cough due to choking on the smoke, which may make the discomfort of people more serious.

[0004] Based on the above-mentioned situation, we found that existing low-pressure sensors are difficult to avoid the above problems. Therefore, we propose a low-pressure sensor that can sense a person's forceful exhalation or cough to control the cessation of smoke generation and has stronger functionality.

By reading the pressure or suction data from the low-pressure sensor, the microcontroller inputs preset parameters such as the number of inhalations and the inhalation time interval, and calculates the time, voltage output, and power parameters required for the electronic cigarette to be inhaled.

[0009] S3. Based on the calculated voltage output and power parameters, the microcontroller outputs specific voltage and power signals through control signals to control the electronic cigarette. The electronic cigarette adjusts according to the specific voltage and power signals output by the microcontroller and controls the amount of air inhaled by the electronic cigarette.

[0048] Brief description of usage: When suction is generated, the low-pressure sensor samples and detects the pressure or suction level inside the e-cigarette and then digitizes it. The converted data is compared with the pressure or suction data of the low-pressure sensor, and the microcontroller is input with preset parameters such as the number of inhalations and the inhalation time interval. Then, the amount of air inhaled by the e-cigarette is controlled according to the calculated voltage output and power parameters.
