Abstract

The application discloses an ultrasonic atomizer and a power control method of ultrasonic atomization. The ultrasonic atomizer comprises a liquid storage cavity, an ultrasonic atomizing piece, a control circuit and a power supply. The liquid storage cavity is used for storing a liquid matrix. The ultrasonic atomizing piece is used for generating oscillation to atomize the liquid matrix. The control circuit is configured to: in the working process of the ultrasonic atomizing piece, acquire a current flowing through the ultrasonic atomizing piece, and determine a target working voltage of the ultrasonic atomizing piece according to the current flowing through the ultrasonic atomizing piece and a target working power; and adjust a voltage provided by the power supply to provide the target working voltage for the ultrasonic atomizing piece. In this way, the corresponding working voltage can be continuously matched for the ultrasonic atomizing piece based on the target working power, so that the ultrasonic atomizing piece has better atomization effect and higher working efficiency.
