The ultrasonic atomizer circuit is composed of the power supply circuit, oscillator circuit and the water level control circuit, and the cirucuit is shown in Figure 3-189. Power supply circuit is composed of the power transformer T, rectifier diodes VDl-VD4, filter capacitors Cl, C2, zener diode VSl and resistor Rl. Water level detection control circuit consists of two electrodes, transistors Vl, V2, resistors R2-R7 and Zener diode VS2. Oscillator circuit consists of transistor V3, capacitors C3-C6, inductors Ll-L3 and the crystal ultrasonic transducer B. Rl-R7 select the 1/4W carbon film resistors or metal film resistors.
