when the motor 12 is used, the driving shaft 121 of the motor 12 rotates and drives the impeller 5 to rotate together, meanwhile, the inner wall of the jack 521 abuts against the guide plate 22, thereby driving the guide plates 22 to rotate together, so that the wind is poured into the heat dissipation hole 113 and carries the hot air generated on the surface of the motor 12 to penetrate out along the gap between the guide channel 3 and the fan blade 52, and then is discharged from the air outlet 112, a large amount of hot air in the accommodating cavity 111 can be discharged, the discharge of heat generated when the motor 12 is used is accelerated, the heat dissipation of the motor 12 is facilitated, the problem of high-temperature damage of the motor 12 is reduced, and the service life of the motor 12 is prolonged.

Wherein, part wind gets into in the inlet air duct 1011 on the induced air cover 101, supply water toward intaking end 1021 through water supply equipment, the heat that the wind carried in some inlet air duct 1011 is taken away to rivers circulation condenser pipe 102, thereby cool down wind, wind after the cooling passes through breather pipe 103 and gets into in the through-hole 114 and then flow through the motor 12 surface, after the temperature on some motor 12 surfaces is taken away to wind, some wind is discharged from louvre 113, remaining wind continues to be discharged from air outlet 112, or continue to get into inlet air duct 1011 and cool down and circulate, thereby the radiating effect of motor 12 has further been improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
