The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1-3, the fan motor with a heat dissipation protection structure of the present invention includes a casing 1, an output end 2 is disposed at one end inside the casing 1, an outer casing 3 is fixedly connected to one end of the casing 1, which is close to the output end 2, a ventilation slot 4 is disposed between the outer casing 3 and the casing 1, and a plurality of connecting blocks 5 are fixedly connected between the outer casing 3 and the casing 1 at equal intervals;

protection cabin 6 has been seted up to the one end that output 2 was kept away from to casing 1's inside, and one side that output 2 was close to in protection cabin 6's inside is equipped with thermoscope 7, and one side that output 2 was kept away from in protection cabin 6's inside is equipped with circuit breaker 8.

The one end that output 2 was kept away from to air channel 4 is trapezoidal, and it is whole to be leaks hopper-shaped, and because air channel 4 keeps away from the one end basin of output 2 great, the air that gets into is more, and along with the entering of air, the basin reduces, leads to air flow rate increase, improves the cooling effect of motor.

The inside of circuit breaker 8 is equipped with two conducting blocks 9, the circuit connection of two conducting blocks 9 and output 2, it is connected with conducting strip 10 to rotate between two conducting blocks 9, the inner wall of circuit breaker 8 and the one end of keeping away from the axis of rotation of conducting strip 10 are equipped with electro-magnet 13, when the motor is in high temperature state for a long time, high temperature is sensed to thermometer 7 in protection cabin 6, switch with signal transmission to circuit breaker 8, electro-magnet 13 circular telegram is inhaled conducting strip 10, circuit breaking with the motor, make motor pause operation, avoid it to work under the high temperature state for a long time.

Fixedly connected with spring 11 between the middle part of conducting strip 10 and circuit breaker 8's the inner wall, the position fixedly connected with iron plate 12 of conducting strip 10 relative electro-magnet 13, electro-magnet 13 can be inhaled conducting strip 10 through iron plate 12, realize the purpose of short circuit, be equipped with insulating gasket between the bottom of iron plate 12 and the conducting strip 10, reset switch 14 of electro-magnet 13 passes circuit breaker 8 and extends to casing 1's outside, separate through insulating gasket between the bottom of iron plate 12 and the conducting strip 10, the point of avoiding motor circuit passes through iron plate 12 and gets into electro-magnet 13.
