Title:
FOCUSED ULTRASONIC ATOMIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/031261
Kind Code:
A1
Abstract:
A focused ultrasonic atomization device, comprising a housing (1), an ultrasonic transducer (2) and a microporous mesh (3); a through cavity (11) is provided inside the housing (1), one end of the through cavity (11) is provided with the ultrasonic transducer (2), the other end is provided with the microporous mesh (3), the ultrasonic transducer (2) comprises a piezoelectric ceramic body (21), the piezoelectric ceramic body (21) has a spherical crown shape, an inner concave surface of the piezoelectric ceramic body (21) faces the microporous mesh (3), and the through cavity (11) is filled with a liquid medium. The ultrasonic atomization device uses a combined structure combining focused ultrasound with the microporous mesh (3), and ultrasound waves emitted by the piezoelectric ceramic body (21) which has a spherical crown shape and has an inner concave surface facing the microporous mesh (3) is high-intensity focused ultrasound, greatly improving the energy of the ultrasonic waves, thereby enabling a large amount of atomization and high atomization efficiency, and being able to atomize a high-viscosity liquid.
