Principle of ultrasonic atomization

Publish Time: 2019-05-09     Origin: Site

The ultrasonic atomizer uses electronic high-frequency oscillation (oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the human hearing range, the electronic oscillation is harmless to humans and animals), and the liquid water molecules are passed through the high-frequency resonance of the piezoelectric ceramic element atomizer. The structure breaks up to produce a natural, flowing mist that does not require heating or adding any chemicals. Energy savings of 90% compared to heated atomization. In addition, a large amount of negative ions will be released during the atomization process, which reacts with the floating smoke and dust in the air to cause precipitation, and at the same time effectively remove harmful substances such as formaldehyde, carbon monoxide and bacteria, so that the air is purified. Reduce the incidence of disease.

Formation process of ultrasonic atomization: 


A disk-shaped ceramic piezoelectric transducer converts electrical energy into mechanical energy, and the transducer receives high-frequency electrical signals from the ultrasonic generator and converts them into mechanical vibrations of the same frequency. The two titanium cylinders amplify the motion and increase the amplitude of the vibration of the atomizing surface. The vibration after the transducer is converted produces a transverse standing wave in the direction along the nozzle, and the sound wave is maximum when it reaches the atomizing surface (the small diameter portion at the foremost end of the nozzle). The liquid is introduced through the nozzle to the atomizing surface. The liquid is appearing on the atomizing surface absorbs the vibration energy of pzt ceramic disc, thereby achieving atomization.
