Abstract

The application provides an ASIC chip of an electronic cigarette silicon microphone and a processing method of the ASIC chip during smoking, including: a capacitance detection module, a main control algorithm module, and a discharge module, and the capacitance detection module is used to obtain the electronic cigarette silicon microphone. The current capacitance value of the MEMS capacitor chip in the MEMS capacitor chip in the The discharge module performs discharge, and the discharge module heats the e-liquid of the electronic cigarette in a wide voltage range through the discharge. The detection of the electronic cigarette silicon microphone in the embodiment of the present invention is more accurate, which ensures that the user will not experience smoking due to changes in voltage when using the electronic cigarette, and improves the use experience of the electronic cigarette.

Description

technical field [0001] The application belongs to the field of electronic cigarettes, and in particular relates to a control chip of a silicon microphone head of an electronic cigarette with dual heating wires and a control method thereof. Background technique [0002] Electronic cigarette is a kind of electronic cigarette which is powered by battery, the movement of airflow is detected by the internal detection module, or the pressure difference of the piezoresistive diaphragm is detected by the pressure sensor to judge whether it is currently in the smoking state, and the current output and working state are controlled by the chip. product. The heating wire atomizes the e-liquid into particles, which are absorbed through the lungs, while exhaling simulated smoke. Electronic cigarettes do not contain tar and other harmful substances in cigarettes, nor do they generate second-hand smoke, nor do they diffuse or linger in confined spaces. Therefore, more and more people are ...
