What is the principle of humidifier?

1. Home humidifiers generally atomize water through ultrasonic waves, and the atomized water vapor is blown out of the enclosure through a fan, thus achieving the effect of humidified air. The utility power after the switching power supply, the output 36V and 12V two voltages. Where 36V power water vapor atomization module and 12V power fan. In the circuit, D1 and D2 are water shortage indicator and work indicator respectively; reed switch is the liquid level detection switch; RT1 is a potentiometer for adjusting the size of the fog. 02 is the core, and its peripheral circuit is the ultrasonic generation circuit. 2. Ultrasonic humidifier ultrasonic waves oscillate at a high frequency of 1.7MHZ to atomize the water into ultra-fine particles of 1-5 microns. Through the pneumatic device to diffuse the water mist into the air, so that the air is moist and accompanied by a wealth of negative oxygen ions, which can purify the air, improve health, and create a comfortable environment.3. Thermal evaporation humidifier is also known as electric humidifier. It works by heating water in the heater to 100 ℃ to produce steam, sent out by the fan.
