This circuit is composed of the step-down rectifier circuit, the electronic timing circuit, the high frequency oscillation high voltage circuit, the ozone generator and the antioxidant pressure pump.etc, as the figure 16-42 shows. The AC transformer T1 is the step-down transformer, it's secondary stage has the 10V AC current, and this current is rectified by the full wave to produce the +12V DC current as the power supply of the IC1 and IC2. The controllable monostable timing circuit is composed of the IC1(555) and R1～R3,C2,AN1.etc. By pressing AN1, you can trigger the monostable state.IC2's high-frequency pulse is amplified by VT1 to drive the high-frequency pulse transformer. The VT1 uses the VMOS type power switch tube.
