Abstract

The embodiment of the invention provides an ultrasonic atomization assembly and an ultrasonic atomization device. The ultrasonic atomization assembly comprises a piezoelectric driving element, an atomization piece and a bearing plate. Wherein the piezoelectric driving element is provided with a first through hole; the atomization sheet and the piezoelectric driving element are arranged in a stacked mode, and a micropore area is arranged at the position, corresponding to the first through hole, of the atomization sheet; the bearing plate is arranged on the surface of the side, away from the piezoelectric driving element, of the atomization piece. A second through hole is formed in the position, corresponding to the micropore area, of the bearing plate; the ratio of the hole diameter of the second through hole to the diameter of the micropore area is larger than or equal to 0.75 and smaller than or equal to 1.5. According to the ultrasonic atomization assembly, vibration loss caused by invalid vibration is effectively reduced, working noise and temperature rise are reduced, and meanwhile the proportion of small particle sizes in atomization particle sizes is increased.

Description

technical field [0001] The invention relates to the technical field of ultrasonic atomization, in particular to an ultrasonic atomization component and an ultrasonic atomization device. Background technique [0002] With the development of medical technology, aerosol inhalation is more and more accepted by people because of its advantages of low damage and high efficacy; while ultrasonic microporous atomization is a fast-developing drug delivery method. [0003] The current ultrasonic microporous atomization component is mainly composed of a piezoelectric ceramic ring and a microporous atomizing sheet; its main working principle is to use the inverse piezoelectric effect of the piezoelectric ceramic ring to generate high-frequency micro-amplitude oscillations to differentiate aerosols. The surface of the substrate makes it form an aerosol of tiny particles with vectoriality, and then scatters in the form of a mist. [0004] However, the existing ultrasonic microporous atomi...
