Ultrasonic atomization structure and ultrasonic atomization device using the same

Abstract

The invention discloses an ultrasonic atomization structure and an ultrasonic atomization device using the same. The ultrasonic atomization structure comprises a liquid receiving tank 12, a liquid absorption medium 15 and an atomization unit, wherein the liquid absorption medium 15 is arranged in the liquid receiving tank 12, and the bottom surface of the liquid absorption medium 15 is immersed in liquid in the liquid receiving tank 12. When the ultrasonic atomization structure is used, the liquid absorption medium 15 absorbs the liquid in the liquid receiving tank 12 and conveys the liquid to one end of the liquid imbibition medium 15, far from the bottom surface of the liquid absorption medium 15, the atomization unit is attached to the end of the liquid absorption medium 15, far from the bottom surface of the liquid absorption medium 15, and the end of the liquid absorption medium 15, far from the bottom surface of the liquid absorption medium 15, is provided with a groove 1501. The ultrasonic atomization structure and the ultrasonic atomization device using the same can atomize the high viscosity liquid into fine drops, and can not cause a superheating phenomenon to the atomization unit.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an ultrasonic atomization structure and an ultrasonic atomization device adopting the structure. Background technique [0002] In many occasions in daily life, liquids need to be dispersed into tiny droplets or aerosols for use, such as disinfection, odor removal, and air humidification. Atomizing or vaporizing liquids is often conducive to the rapid and uniform diffusion of liquids. Medical nebulizers usually include a heating unit or a gas compression pump. The former will cause the drug to decompose due to high temperature; the latter is not only noisy, but also often contaminates the drug due to direct contact between gas and liquid. [0003] In order to meet the special requirements of drug delivery through the respiratory tract, manufacturers have developed ultrasonic atomization technology in recent years, that is, microporous atomization sheets adhered to piezo...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the ultrasonic atomization equipment on the market directly set the ultrasonic atomization unit in the liquid. This design can only be used to atomize water-based or low-viscosity liquids, and cannot be used to atomize high-viscosity liquids.

Because the viscous liquid film will block the micropores on the atomizing sheet, thus blocking the atomization, and eventually the temperature of the piezoelectric ceramic sheet will rise or even be damaged.
