Problems solved by technology

This structure will directly contact the microporous stainless steel sheet with the drug. Since the general drug has a certain pH, it is likely to corrode this material and shorten the service life. When the air vibration is frequent, the mesh is easily broken when the mesh is corroded, and the fragments are inhaled by the patient into the lungs, resulting in medical accidents
[0005] 2. The metal sheet is processed by laser micromachining technology, but the minimum pore size of this processing technology can only be about 5 microns, and the pore size distribution is not very uniform. The size of the pore size directly determines the size of the spray particles and also affects the drug. curative effect will be affected

Abstract

The present invention relates to a composite atomizing plate and a manufacturing method thereof. The composite atomizing plate comprises a metal substrate and a piezoelectric ceramic ring piece fixed to an upper surface of the metal substrate. A first through hole is formed in a central region of the metal substrate, while a second through hole is formed in a central region, corresponding to the first through hole, of the piezoelectric ceramic ring piece. A positive pad and a negative pad are also disposed on an upper surface of the piezoelectric ceramic ring piece separately. The composite atomizing plate also comprises a polyimide film that is fixed to the upper surface of the metal substrate and that completely covers the first through hole. A plurality of atomizing pores are formed in the polyimide film with two ends of each atomizing pore communicating with the first through hole and the second through hole, respectively. The composite atomizing plate has the characteristics of good corrosion resistance and good flexibility; thus, net breaking or broken net fragments may be avoided during high-speed vibration. The micropores for atomization may have a pore size of 1 micron minimum, and normative and uniform pore distribution can be ensured, such that particles ejected have a smaller diameter.

Description

technical field [0001] The invention relates to an atomizing sheet applied to a medical atomizer, in particular to a composite atomizing sheet and a manufacturing method thereof. Background technique [0002] The structure of the piezoelectric ceramic ultrasonic atomizer used at this stage is mostly bonded or welded by a metal substrate 1 and a piezoelectric ceramic ring 2, and its structure is as follows: figure 1 shown. After the piezoelectric ceramic ring is energized, the piezoelectric ceramic ring generates stretching vibration along the hair direction under the action of the inverse piezoelectric effect and drives the metal substrate to resonate. It drives the transmission of the liquid, and there are continuously tiny droplets overflowing from the micropores, realizing the atomization of the liquid. [0003] The existing atomized sheet has the following problems: [0004] 1. SUS304 stainless steel sheet is mostly used to directly laser process micropores, and then ...
