The multi-function ultrasonic humidifier circuit

Published:2011/8/23 22:08:00 Author:Borg | Keyword: multi-function, ultrasonic humidifier | From:SeekIC

When there is some water in the humidifier, the water level switch K2 is pulling in automatically. When the power supply K1 is put through, the voltage is added on the base electrode of V2 by V1, W2, L2, R3 and R4, V2 forms the oscillator with its external elements, the oscillator frequency is in ultrasonic waveband. When the oscillating voltage of certain amplitude is added on the converter HD, HD will generate the ultrasonic wave, and is will form resonance in the fog tube, which has some effect on water and fog is generated. By adjusting W1 and W2, the amplitudes of W1 and W2 can be changed, so the fog content is adjusted.
