Abstract

An electronic atomization apparatus (100) and a control method. The electronic atomization apparatus (100) includes: a liquid storage cavity (11) configured to store a liquid substrate; an ultrasonic atomization element (12) which is able to be driven by an alternating current to atomize the liquid substrate to generate aerosols; a drive unit which provides the alternating current to the ultrasonic atomization element (12); and a controller (221) configured to: control the drive unit to provide a frequency-varying alternating current to the ultrasonic atomization element (12), so as to obtain a first frequency at maximum power of the ultrasonic atomization element (12), and a second frequency when a phase difference between a voltage and a current of the ultrasonic atomization element (12) is zero; and control the drive unit to provide an alternating current with a third frequency to the ultrasonic atomization element (12) to drive the ultrasonic atomization element (12) to atomize the liquid substrate, where the third frequency is between the first frequency and the second frequency. In the electronic atomization apparatus (100), the third frequency between the first frequency and the second frequency is used as the operating frequency of the ultrasonic atomization element (12), so that the ultrasonic atomization element (12) tends to operate in an optimal resonant state as much as possible.
