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.
