Principle of ultrasonic atomizer
The use of piezoelectric ceramic ultrasonic oscillation inherent characteristics, through certain means of oscillation circuit and piezoelectric ceramic, the inherent oscillation frequency of resonance, can be directly with the liquid atomization piezoelectric ceramic contact into tiny particles of 1--3 M. The principle is that the ultrasonic oscillation circuit, transmission to the surface of the piezoelectric ceramic vibrator, piezoelectric ceramic vibrator will produce axial mechanical resonance changes, the change of mechanical resonance and then transmitted to contact with the liquid, the liquid surface uplift, and the occurrence of cavitation in the surrounding uplift, resulting from the impact of cavitation the vibration frequency of wave oscillator is repeated, the surface tension of the liquid surface wave with finite amplitude. This tension wave scattering head, the atomization of liquid, produced a large number of negative ions at the same time. From the point of view of energy conversion, the atomization process is actually the process of converting electrical energy into mechanical energy and thermal energy, and how to make the heat energy loss lower.
