Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as image 3 , Figure 4 and Figure 6 As shown, the piezoelectric ceramic ultrasonic atomizer includes a connected metal diaphragm 1 and a piezoelectric ceramic ring 2, the outer diameter of the piezoelectric ceramic ring 2 is less than or equal to the diameter of the metal diaphragm 1, and the The central area of ​​the piezoelectric ceramic ring piece 2 is provided with a through hole 4, and the area corresponding to the central area of ​​the metal diaphragm 1 and the central ceramic ring piece 2 is provided with a group of dense atomization holes 3, and the atomization holes 3 face The first opening diameter of the piezoelectric ceramic ring piece 2 is smaller than the second opening diameter of the atomization hole 3 facing away from the piezoelectric ceramic ring piece 2, and the outline of the wall of the atomization hole 3 is curved. The metal diap...

Abstract

The invention discloses a piezoceramic ultrasonic atomizer. The piezoceramic atomizer comprises a metallic membrane and a piezoceramic ring piece which are connected, wherein the outer diameter of the piezoceramic ring piece is smaller than or equal to the diameter of the metallic membrane; a through hole is formed in the center of the piezoceramic ring piece; a group of dense atomizing holes are formed in an area where the metallic membrane corresponds to the central area of the piezoceramic ring piece; the diameter of each first opening, facing to the piezoceramic ring piece, of each atomizing hole is smaller than that of each second opening, deviating from the piezoceramic ring piece, of each atomizing hole; and the contour line of the wall of each atomizing hole is a curve. Each atomizing hole with the structure can reduce the change rate of a cross section of each atomizing hole in an axis direction of the hole, and reduce the energy loss caused by bigger change of the cross section; and besides, the atomization amount of the atomizer is increased, and the atomizing effect is improved remarkably.

Description

technical field [0001] The invention relates to a device for conveying, transporting and atomizing liquid, in particular to an atomizer which adopts piezoelectric ceramics for ultrasonic atomization. technical background [0002] In production and life, the process of breaking up a continuous liquid into small mist droplets is called atomization. The atomization process is actually an energy conversion process, that is, the input electrical energy is converted into the mechanical energy of small droplets and other forms of energy generated at the same time. [0003] The structure of piezoelectric ceramic ultrasonic atomizers currently used is mostly bonded or welded by a metal diaphragm and a piezoelectric ceramic ring. Its structure is as follows: figure 1 shown. After the piezoelectric ceramic ring is energized, under the action of the inverse piezoelectric effect, the ceramic ring generates stretching vibration in the radial direction and drives the metal diaphragm to p...
