1. A full-wave drive circuit for an ultrasonic atomizing sheet, comprising a power module (1), a microprocessor (2), a high-frequency square wave generation circuit (3), an NMOS transistor (Q1) and a resonance circuit (4); an output end of the power module (1) is electrically connected to the resonance circuit (4); an output end of the microprocessor (2) is electrically connected to a gate of the NMOS transistor (Q1) through the high-frequency square wave generation circuit (3), wherein the NMOS transistor (Q1) and an ultrasonic atomizing sheet (W) are both connected to the resonance circuit (4), and the resonance circuit (4) is configured to convert, based on the NMOS transistor (Q1), a voltage signal output by the high-frequency square wave generation circuit (3) into a full-wave oscillation signal, so as to drive the ultrasonic atomizing sheet (W) to perform full-wave oscillation.
