Title:
DRY-BURNING PREVENTION DEVICE OF ELECTRONIC CIGARETTE, AND DRY-BURNING PREVENTION CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/033886
Kind Code:
A1
Abstract:
A dry-burning prevention device of an electronic cigarette and a dry-burning prevention control method therefor. A microcontroller of the dry-burning prevention device is electrically connected, in sequence, to a half-bridge boost circuit, a chopped-wave buck circuit, an atomizer and an atomizer resistance-value detection module, and is then connected back to the microcontroller from same; feedback circuits are respectively connected between the chopped-wave buck circuit and the atomizer and between the chopped-wave buck circuit and the half-bridge boost circuit, and the feedback circuits both access the micro controller; the feedback circuits respectively feed back output voltage signals of the half-bridge boost circuit and the chopped-wave buck circuit, so as to adjust output voltages of the half-bridge boost circuit and the chopped-wave buck circuit and keep the output voltages stable; and when an electronic cigarette is working, the atomizer resistance-value detection module continuously detects a resistance value of the atomizer according to a set interval time of the microcontroller, and when the resistance value of the atomizer exceeds a set dry-burning prevention resistance value and the number of continuous exceeding times reaches a preset number of times, the microcontroller instructs the half-bridge boost circuit or the chopped-wave buck circuit to close the output, and the electronic cigarette automatically stops working.
