Electronic cigarette chip and electronic cigarette

Abstract

The invention relates to an electronic cigarette chip which is used for controlling the switching on and off of an electronic cigarette adopting a capacitive microphone according to capacitance change of the capacitive microphone. The electronic cigarette chip comprises a microphone capacitance detecting module and a heating wire driving circuit which are connected with each other, wherein the microphone capacitance detecting module is used for detecting the capacitance of the capacitive microphone, converting the capacitance of the capacitive microphone into a comparison signal, comparing the comparison signal with a smoking threshold value, and controlling the open and close of the heating wire driving circuit according to the comparing result. As the sensibility and reliability of the electronic cigarette chip are effectively improved, the electronic cigarette can generate smoke even under little sucking force, the phenomenon of smoking by false triggering is avoided, and the electronic cigarette chip solves a series of problems that the electronic cigarette is heated excessively, a plastic shell of the electronic cigarette is burnt, the service life of the electronic cigarette is shortened, the yield is low and the like caused by the long-time continuous false triggering smoking action of the conventional electronic cigarette chip.

Description

technical field [0001] The invention relates to articles for smokers, in particular to an electronic cigarette chip, and also to an electronic cigarette. Background technique [0002] Disposable electronic cigarettes are popular among smoking consumers because of their low price and convenient use. At present, disposable electronic cigarettes generally use switch-type microphones to detect smoking actions. When there is a smoking action, under the action of negative air pressure, the positive and negative poles of the switch-type microphone are closed, and the control circuit detects that the positive and negative poles of the microphone are closed. , start to drive the heating wire to generate heat to generate smoke, so as to realize the effect of automatically generating smoke when there is a smoking action. [0003] In order to improve the sensitivity, that is, the heating wire can be driven to generate heat and generate smoke under a small suction force, it is necessary...

AI Technical Summary

Problems solved by technology

[0006] Based on this, it is necessary to address the problem of low reliability of traditional electronic cigarette chips, provide an electronic cigarette chip with high reliability and high smoking sensitivity, and then provide an electronic cigarette with this electronic cigarette chip
