Generally speaking, the ultrasonic atomizer is a piezoelectric ceramic component used for atomization and humidification, and its physical model is an emitting piezoelectric ceramic transducer. According to the needs of energy output, the two electrodes of the atomizer are generally designed to be large and one small. The large side is generally called the large silver surface (also called the surface electrode), and the small side is generally called the small silver surface (also called the driving electrode or dot). Electrode). At the same time, in order to facilitate the connection with the peripheral driving circuit, lead wires should be welded on both electrodes.

1. The working principle of ultrasonic atomization sheet

Ultrasonic vibration produces the interaction between micro shock waves and finite amplitude surface tension waves caused by cavitation under the liquid surface. When the amplitude reaches a certain value, droplets fly out of the wave crest to form mist.

2. The role of ultrasonic atomizer

It can atomize water or aqueous solution without heating, and is widely used in household humidity adjustment, industrial humidification, and medical treatment for respiratory diseases. During the atomization process, a large amount of negative ions will be released, which will be combined with the floating smoke and dust in the air. The electrostatic treatment will precipitate and filter them, which can effectively remove harmful substances and odors such as formaldehyde, carbon monoxide, bacteria and so on.
