Title:
ULTRASONIC ATOMIZATION PIECE AND ATOMIZER
Document Type and Number:
WIPO Patent Application WO/2021/078127
Kind Code:
A1
Abstract:
An ultrasonic atomization piece and an atomizer. The ultrasonic atomization piece comprises a piezoelectric ceramic substrate, and the piezoelectric ceramic substrate comprises a first surface (221) and a second surface (222) that are disposed opposite one another; a first electrode (2211) is coveringly disposed on the first surface (221), and a second electrode (2221) is coveringly disposed on the second surface (222); the first electrode (2211) and the second electrode (2221) are symmetrically disposed relative to the piezoelectric ceramic substrate; and the coverage area of the first electrode (2211) on the first surface (221) is equal to the coverage area of the second electrode (2221) on the second surface (222). The ultrasonic atomization piece of an atomizer is disposed at the middle part of an e-liquid tank (3), and the first and second surfaces (221, 222) of the ultrasonic atomization piece are each in contact with an e-liquid guide body (23). When the ultrasonic atomization piece is connected to an external power supply, ultrasonic atomization is simultaneously performed on the first and second surfaces (221, 222) of the ultrasonic atomization piece, and heat from ultrasonic atomization is absorbed by the e-liquid within the e-liquid tank (3) so that less heat is transferred to the housing of the atomizer, thereby avoiding scalding a user.
