The DGK—63L double functions disinfection cabinet circuit is composed of three parts: the infrared ray high temperature generating circuit, the ozone generating circuit and the electronic timing control circuit. The electronic timing control circuit is composed of the AC step-down circuit, the rectifier voltage stabilization circuit and two monostable timing control circuits. The voltage stabilization circuit outputs the +9V DC voltage as the power supply of the control circuit. The button type monostable trigger timing circuit is composed of the IC1(555), R3，C4 and AN1, if you press AN1, the IC1's trigger setting port pin-2 connects to the ground electric potential to make the 555 to set, so pin-3 has the high electric potential, relay K1 closes, it's connection point K1-1 closes too.
