Optimization of Control System for Electromagnetic Heating Cigarette Device

Abstract

Abstract To solve the problems of electromagnetic heating cigarette devices in heating speed and temperature control accuracy, the optimization of the control system was carried out based on the current device. And the special control system for the electromagnetic heating cigarette device was designed, which was powered by a lithium battery device and designed with a half-bridge push-pull double resonant capacitor. According to the test, the prototype can preheat at 350 °C in 7 seconds at the fastest, with an average rate of 44.33 °C/s; The maximum temperature deviation at the constant temperature stage cannot exceed 5 °C, and the temperature control accuracy can be ± 1.47%; in the simulated suction stage, the prototype can be warmed back from 280 °C to 340 °C in 3 seconds. Compared with the original dual-tube single-capacitor resonant circuit, it has nearly double the heating power. The experimental data shows that the temperature rise rate and temperature control accuracy was significantly improved, giving full play to the performance advantages of electromagnetic heating.
