Integrated ultrasonic atomization device

Abstract

The invention relates to the field of machine design, in particular to an integrated ultrasonic atomization device. The integrated ultrasonic atomization device comprises a substrate; a plurality of ultrasonic atomization device parts are arranged on the substrate; the ultrasonic atomization device parts comprise piezoelectric ceramic ring pieces and micropores through which water molecules pass;the piezoelectric ceramic ring pieces sleeve the corresponding micropores; interference prevention devices for shortening the ultrasonic vibration transmission range are arranged on the substrate; andthe corresponding interference prevention devices are arranged between any two ultrasonic atomization device parts. The corresponding interference prevention devices for shortening the ultrasonic vibration transmission range are arranged between any two ultrasonic atomization device parts on the substrate, so that the situation that the atomization efficiency is affected due to the fact that ultrasonic between the ultrasonic atomization device parts possibly transmits in a medium mutually and mutual interference is caused and working impedance is formed mutually is avoided.

Problems solved by technology

[0002] At present, large-scale atomization devices are widely used in the industrial field, such as using large-scale atomization devices to spray pesticides, sterilize and prevent epidemics, or remove smog in cities. However, the current large-scale atomization devices are relatively large in size. A large number of dense ultrasonic atomization devices are integrated on a substrate. In order to improve the atomization efficiency, it is necessary to increase the area of ​​the substrate, resulting in a larger volume of large atomization devices.

[0003] However, the real reason why it is impossible to integrate more and denser ultrasonic atomization devices on one substrate is that when multiple ultrasonic atomization devices (mainly piezoelectric ceramic sheets) are integrated on one substrate, due to the piezoelectric ceramic sheets It is the working principle of ultrasound. The ultrasonic vibration energy will be transmitted to each other in the same medium, causing mutual interference, forming mutual working impedance, and affecting the atomization efficiency. Therefore, in order not to cause mutual interference, the distance between the ultrasonic atomization devices will be far away. Therefore, it is impossible to integrate more and denser ultrasonic atomization devices on one substrate, and the atomization efficiency is low
