Patent ID: 11564414

Abstract:
Disclosed are an ultrasonic atomization control system and an electronic cigarette. The system includes: a current feedback circuit and/or a voltage feedback circuit, a microcontroller unit, a push-pull circuit, and an oscillator driving circuit; wherein the push-pull circuit is coupled between the microcontroller unit and the oscillator driving circuit, the current feedback circuit and/or the voltage feedback circuit are/is coupled between the oscillator driving circuit and the microcontroller unit; and the oscillator driving circuit is configured to be connected with a load; wherein the microcontroller unit is configured to output a pulse width modulation signal with a predetermined frequency and voltage to the push-pull circuit, judge a current and/or a voltage fluctuation fed back by the current feedback circuit and/or the voltage feedback circuit are/is greater than a threshold, and stop operation of the load if the fluctuation is greater than the threshold.
