Abstract

The invention discloses a control circuit of a multi-gear adjustable micro-grid atomizer. The control circuit comprises a power source, a key module, a single chip microcomputer, an atomization driving module, a display module and an atomization piece. A key K1 of the key module is a start / stop key, a key K2 is a low-gear key, a key K3 is a middle-gear key, and a key K4 is a high-gear key; an LED1 of the display module is a power indicator lamp, an LED2 and an LED3 are start / stop indicator lamps, an LED4 is a low-gear indicator lamp, an LED5 is a middle-gear indicator lamp, and an LED6 is a high-gear indicator lamp; according to the atomization driving module, a PWM signal with a fixed working frequency is generated by a single-chip microcomputer and supplied to an NMOS tube, then boosting is conducted through a triangular inductor, square waves obtained after boosting enter an atomization piece, and the atomization piece can scatter water drops and atomize the water drops. The net type atomizer with the control circuit has the advantages of being high in atomization efficiency, small in residual medicine amount, low in noise, small and light, and meanwhile the influence of heat generated by ultrasonic vibration liquid on medicine is reduced.
