Power supply circuit is composed of the power switch s, fuse FU, power transformer T, rectifier diodes VD1 ~ VD4, filter capacitor C1 and three-terminal regulator integrated circuit IC1. Temperature detection control circuit is composed of the thermistor RT, voice control integrated circuit IC2, transistor V, relay K, capacitors C2, C3, resistors RI ~ R3 and LEDs YL1, VL2. RI uses the 1/4W carbon film resistor or metal film resistor; R2 and R3 select the 1/2W carbon film resistors.
