1. An output control circuit for an electronic cigarette which comprises a battery assembly and an atomizer, the output control circuit comprising a controller, a first switching circuit, a driving circuit and a second switching circuit, the controller used to control switching-on or switching-off of the first switching circuit, and to provide pulse-width modulation (PWM) signals to the driving circuit;
the first switching circuit respectively electrically connected with the battery assembly, the controller and the atomizer;
the driving circuit electrically connected with the controller, the driving circuit used for driving to switch on or switch off the second switching circuit according to the PWM signals;
the second switching circuit respectively electrically connected with the battery assembly, the driving circuit and the atomizer;
the controller electrically connected with the battery assembly;
wherein the first switching circuit, the atomizer and the second switching circuit are electrically connected in series, the atomizer is switched on when the first switching circuit and the second switching circuit are switched on simultaneously.
