The utility model will be further explained with reference to the drawings.

Referring to fig. 1 to 3, a small-sized motor for home appliances having a safety structure includes: motor 1, evenly be connected with fin 2 on the motor 1, can absorb the heat that motor 1 produced through fin 2 and distribute away, thereby reduce the produced heat of motor 1, motor 1's one end lateral wall fixedly connected with links up post 4, peg graft electric wire 5 and linking post 4, thereby guarantee that electric wire 5 connects and can not receive external influence and the damage appears, threaded connection has adjusting screw 7 on one side of linking post 4, it has clamp plate 8 to establish in linking post 4, it promotes clamp plate 8 decline and removes to rotate adjusting screw 7 can pass through threaded connection's relation, thereby the realization is fixed to electric wire 5's centre gripping, avoid unexpected the droing, the one end of linking post 4 extends into motor 1 inside.

Wherein, slot 6 is seted up at the intermediate position that links up post 4, and slot 6 link up in the centre that links up post 4, peg graft into slot 6 with the joint of electric wire 5 in, be located and fix on the board of placing of 6 inside walls of slot, later rotate adjusting screw 7, make adjusting screw 7 push down clamp plate 8 descend under threaded connection's characteristic, because adjusting screw 7's one end is rotated and is connected on clamp plate 8 lateral wall, clamp plate 8 descends and forms the centre gripping to the joint of electric wire 5, it still is convenient for dismantle when having guaranteed to connect stably, clamp plate 8 is in order to laminate with slot 6's lateral wall, especially establish clamp plate 8 for semi-circular structure.

Wherein, an inner chamber 9 is established in the inside of motor 1, the inner bag 10 has been established simultaneously in inner chamber 9, some important subassemblies of motor 1 are all concentrated and install in inner bag 10 like rotor stator, consequently, inner bag 10 is the main heat source body when motor 1 operates, consequently adjust a hollow circular cylinder's bluff piece 11 on inner bag 10, bluff piece 11 is the foamy copper preparation that the thermal conductivity is good, can come out the heat guide of inner bag 10 through bluff piece 11, reduce the heat of inner bag 10 self, thereby avoid the inside subassembly of inner bag 10 to influence the operation because of high temperature.

Wherein, fin 2 is the loop configuration, and the inner circle lateral wall extends into in the inner chamber 9, and fix on the lateral wall of fin 11, heat that draws forth through fin 11 can disperse to transmit to four fin 2 on, thereby realize the radiating effect, ventilation slot 3 has all been seted up at the both sides lateral wall of every fin 2, wind can flow in ventilation slot 3 when can be convenient for have wind through ventilation slot 3, thereby improve radiating effect, the volume that makes fin 2 because of ventilation slot 3 diminishes when there is no wind, thereby make its thermal capacity reduce, can improve thermal giving off, thereby realize the efficient cooling, the one end that links up post 4 extends into in the inner chamber 9, the one end fixed connection that links up post 4 is located in the inner chamber 9 is on the one end lateral wall of inner bag 10, and with the subassembly electric connection in the inner bag 10.

It is specific, in inserting slot 6 with the joint of electric wire 5, then rotate adjusting screw 7 and promote the clamp plate 8 and remove, it is fixed to suppress electric wire 5 joint, thereby realize electric wire 5 and linking up the stable connection of post 4, again because the mode that electric wire 5 pegged graft is connected with linking up post 4, consequently can avoid electric wire 5 to be in the condition with external contact, reduce electric wire 5 and external contact and can effectually avoid falling because of the emergence of the long-time some accidents that cause that are in the exposure state easily of electric wire 5, can guide the giving off to the heat that inner bag 10 produced through casing 11 and fin 2, thereby realize efficient cooling effect.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
