CIRCUIT FOR ULTRASONIC ELECTRONIC CIGARETTE AND ULTRASONIC ELECTRONIC CIGARETTE

Document Type and Number:

WIPO Patent Application WO/2018/223999

Kind Code:

A1

Abstract:

Disclosed are a circuit for an ultrasonic electronic cigarette and an ultrasonic electronic cigarette. The circuit for an ultrasonic electronic cigarette comprises an ultrasonic atomization member, a control circuit, a first driven oscillator circuit, a second driven oscillator circuit, and a power supply circuit. The control circuit is electrically connected to a first end of the ultrasonic atomization member by means of the first driven oscillator circuit. The control circuit is electrically connected to a second end of the ultrasonic atomization member by means of the second driven oscillator circuit. The circuit for an ultrasonic electronic cigarette further comprises a detection circuit. The detection circuit has an output end electrically connected to the control circuit and a detection end connected between the ultrasonic atomization member and the first driven oscillator circuit or between the ultrasonic atomization member and the second driven oscillator circuit. The present invention enables two ends of the ultrasonic atomization member to operate simultaneously and efficiently, such that the ultrasonic atomization member generates less heat, and has low energy loss, long service life, low power supply costs and a small size. When there is an offset in a natural frequency of the ultrasonic atomization member, an oscillation frequency can be adjusted quickly, such that the ultrasonic atomization member remains in a resonant state, thereby maintaining highly efficient and stable atomization performance to the maximum extent.
