Control circuit of steam electric iron

The utility model relates to a circuit field indicates a control circuit of steam electric iron especially, the utility model discloses a ball formula infrared ray motion detection circuitry, micro -processing chip U1 combines together, can be to ball formula infrared ray sensor's in the circuit pulse signal real -time supervision, the velocity of movement of ball removes and changes along with the electric iron among the ball formula infrared ray sensor, infrared receiving tube and infrared emission control produce pulse signal and export micro -processing chip U1 to, the signal that micro -processing chip U1 corresponds according to the time -charactaristic change of pulse signal output, control the frequency of operation of pump control circuit water pump, the messenger draws water theflow and and then changes, thereby realize the automatic effect that changes of electric iron steam volume, energy consumption control circuit can propose high energy's utilization greatly, which is favorable to environment p
