Abstract

The invention discloses a piezoelectric ceramic ultrasonic atomizing sheet, comprising a piezoelectric ceramic sheet group and a metal sheet group, wherein the piezoelectric ceramic sheet group consists of at least two piezoelectric ceramic sheets, and the metal sheet group consists of at least one metal sheet. In the piezoelectric ceramic sheet group, through holes are arranged on the piezoelectric ceramic sheets; the piezoelectric ceramic sheets and the metal sheets are mutually crossed and overlapped; and the metal sheets cover the through holes entirely. The piezoelectric ceramic ultrasonic atomizing sheet disclosed by the invention is in a multilayer clamping structure, the metal sheets and the piezoelectric ceramic sheets have high bonding strength and are difficult to fall of, so that the metal sheets of one atomizing sheet are combined in various vibration modes, namely axial bending vibration and radial stretching vibration, is realized. Therefore, the vibration modes of the atomizing sheet with the structure are increased and the atomizing effect range of the atomizing sheet is widened.

Description

[0001] Technical field [0002] This patent involves a atomization tablet for liquids for atomization, especially an ultrasonic atomizer with piezoelectric ceramic materials. [0003] Background technique [0004] The effect of liquid vibration through the voltage of the voltage ultrasonic lid tablets can atomize it. This is a well -known technology, that is, the liquid molecular structure of the liquid molecularity is dispersed through high -frequency vibration. [0005] In the existing technology, the voltage ultrasonic ultrasonic atomizer is mainly used in two forms of single -layer metal double -layer ceramic clamping type and single -layer metal single -piece ceramic sheet.The plane vibration (axial bending vibration and radial telescopic vibration) mode of the tablet to drive metal membrane vibration and liquid atomization, such as the patent number 200320110900.9, named "Ultrasonic Crusterization Moom Tablets" in China.The atomization tablets of the patent number of 201020...
