The switch II 103 that controls on electrical equipment II is simultaneously received the induced signal of touch sensor 6 and the detection signal of rotation sensor 5
Time, controlling switch II 103 Guan Bi, closed-loop path II 10 is energized, and relay coil II 102 is energized, and then, relay coil II controls list
Knife-like switch is opened, normally closed relay II 74 power-off, and now, control circuit 8 power-off, motor 2 passes through without DC current, and motor 2 stops
Spline is moved, and flabellum 3 stops operating, and burns out motor 2 to prevent control circuit 8 unidirectional current conduction time long.
The induced signal of touch sensor 6 or the detection signal of rotation sensor 5 is received only when controlling switch II 103
During either signal, closed-loop path II 10 no power, relay coil II 102 no current passes through, and single knife switch is not responding to, and the most normally closed continues
Electrical equipment II 74 is still in on-state.
Whether this utility model has hands to touch by the touch sensor 6 inductive electric fan outer housing 4 arranged, and can will touch
The situation of touching feeds back to control circuit 8, with the break-make of related switch in control circuit 8, and then promotes control circuit 8 to respond；And control
Circuit 8 processed can convert alternating current to unidirectional current by the rectification circuit 71 arranged, thus shortens the dwell time of flabellum 3,
Realize quickly stopping the purpose of electric fan；Furthermore, the rotation sensor 5 that this utility model is arranged then can be according to detection motor 2
Output shaft rotation situation responds control circuit 8, to prevent because in control circuit 8, unidirectional current conduction time is long and burn out
The phenomenon of motor 2, improves the security reliability of electric fan further.
