ULTRASOUND-BASED AEROSOL-GENERATING APPARATUS

Title:

ULTRASOUND-BASED AEROSOL-GENERATING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/215650

Kind Code:

A1

Abstract:

An ultrasound-based aerosol-generating apparatus is provided. The aerosol-generating apparatus, according to some embodiments of the present disclosure, may comprise: a liquid storage tank for storing a liquid-type aerosol-forming substrate; a wick for absorbing the stored aerosol-forming substrate; an ultrasonic vibrator for generating aerosol by vaporizing the absorbed aerosol-forming substrate through ultrasound; and a control part for controlling the ultrasonic vibrator. Here, at least a portion of the wick and at least a portion of the ultrasonic vibrator are implemented so as to have a flat shape and may be disposed so as to tightly adhere to each other. As a result, the area of vaporization is maximized, and the amount of atomization may be greatly increased.
