Method and circuit for ultrasonic atomization electronic cigarette control

Abstract

The invention discloses a method and a circuit for ultrasonic atomization electronic cigarette control. The method comprises: starting an ultrasonic atomizing sheet to work, recording working time H1of the ultrasonic atomizing sheet; comparing downtime T0 and set downtime t0; if T0>=t0, a heating wire atomizing tobacco tar in full power, recording working time T1 of the heating wire; if T0<t0, calculating output power P1 of the heating wire; the heating wire working in the output power P1; comparing the working time T1 of the heating wire with a preset working time t1 of the heating wire, ifT1>=t1, the heating wire stopping work, the ultrasonic atomizing sheet continuing to work; comparing the working time H1 of the ultrasonic atomizing sheet with preset excessive smoking protection timeH, if H1>=H, the ultrasonic atomizing sheet stopping work, and an electronic cigarette stopping work. When the circuit is started, working state of a high-frequency ultrasonic atomizing sheet when auser smokes last time is determined to decide whether the heating wire should be started this time, and output power of the heating wire makes power utilization of the whole electronic cigarette in higher efficiency, and smoke amount of the electronic cigarette more uniform.

Description

technical field [0001] The invention relates to an electronic cigarette, in particular to a control method and circuit for an ultrasonic atomization electronic cigarette. Background technique [0002] Electronic cigarettes have the same appearance and taste similar to cigarettes, simulating the feeling of smoking, for smoking cessation or for smoking. Among them, the electronic cigarette includes an atomizer, which mainly uses the heating wire in the atomizer to atomize the e-liquid to form smoke, providing users with the feeling of swallowing clouds, but the output power of the heating wire in the atomizer is very high , When the heating wire works for a long time, it is easy to crack the smoke oil into harmful substances such as carbon monoxide, which will affect human health. In the existing atomization method, due to the large area of ​​the atomization sheet, the oil-conducting material and the atomization sheet are in plane contact. When the high-frequency atomizing s...
