Title:

ULTRASONIC ATOMIZER

Document Type and Number:

WIPO Patent Application WO/2021/088948

Kind Code:

A1

Abstract:

The present invention relates to an electronic cigarette set, in particular to an ultrasonic atomizer, comprising an e-liquid guide assembly (2); the e-liquid guide assembly comprises an e-liquid guide ceramic (21) which makes direct contact with an e-liquid, e-liquid guide cotton (22) which is located below the e-liquid guide ceramic and is contactingly connected to a surface of the e-liquid guide ceramic, and springs (23) which are located between the e-liquid guide ceramic and the e-liquid guide cotton and abut the e-liquid guide cotton against an atomization piece (322). The e-liquid guide ceramic is a solid ceramic body, and micropores which are used for conducting the e-liquid and vapor are integrally formed on the e-liquid guide ceramic. The present invention uses a combination of an e-liquid guide ceramic and e-liquid guide cotton to guide an e-liquid. In an ultrasonic atomization process, the e-liquid guide amount of the e-liquid guide assembly is fixed, such that the atomization efficiency of ultrasonic atomization is high, the amount of vapor is stable, and atomization not being enough to absorb e-liquid drops due to an ultrasonic atomization piece being soaked in e-liquid or the ultrasonic atomization piece being dry-burnt due to a small amount of e-liquid is avoided.
