What is the structure and working principle of the ultrasonic atomizer? The following for everyone:
Whether the tube tube, or transistor-type ultrasonic atomizer basically consists of four major components, namely: power circuit, high-frequency generator, atomization tank, cooling air supply device and circuit. Some ultrasonic atomizer also designed the water level, water temperature control alarm circuit. In the tube-type ultrasonic atomizer power supply circuit, the line is different, some of the 220V mains boost after the pressure twice, and some of the electricity directly after the three times the power supply for the tube to provide 600V or 700V or so of the screen pressure and 300V or so. The transistor-type ultrasonic atomizer power supply circuit is 220V mains step-down rectifier for the 40V DC voltage, the power supply circuit is the source of high-frequency generator energy supply, high-frequency generator The oscillation frequency is based on the natural frequency of the piezoelectric chip to be designed, generally selected between 1.4MHZ-1 .7MHZ. The high frequency power output from the high frequency generator is applied to the positive and negative poles of the piezoelectric wafer, and the piezoelectric wafer generates mechanical oscillation, so that the high frequency power is converted by the piezoelectric wafer to the ultrasonic wave in the thickness direction of the wafer. As the ultrasonic wave has the ability to destroy the surface inertia and surface tension and cavitation effect, when the liquefaction surface tension wave is enough, it will fly out at the peak air mist. Ultrasonic atomizer structure and working principle is the case.
