Specifically, as shown in fig. 13, the switch structure 201c includes a fixed plate 201c-1 fixedly disposed at one end of the air duct 201a near the air storage seat 201b, a through hole communicating with the air duct 201a is penetrated in the middle of the fixed plate 201c-1, sliding plates 201c-2 are disposed on two sides of one surface of the fixed plate 201c-1, and the sliding plates 201c-2 are symmetrically disposed on the fixed plate 201c-1 in a sliding manner, so as to open or close the through hole in the center of the fixed plate 201 c-1; the surface of the sliding plate 201c-2 is fixedly provided with a guide block 201c-3; one end of the air storage seat 201b, which is close to the air guide pipe 201a, is rotatably provided with a rotating plate 201c-4, one side surface of the rotating plate 201c-4 is in sealed rotating connection with the fixed plate 201c-1, two guide grooves 201c-5 are formed in the rotating plate 201c-4, the two guide grooves 201c-5 are all arranged in an arc shape, the radian is 45 degrees, and the two guide grooves are symmetrically arranged on the rotating plate 201c-4 and matched with the guide blocks 201c-3; a pulling rod 201c-6 is arranged between the rotating plate 201c-4 and the U-shaped frame 302a, and two ends of the pulling rod 201c-6 are respectively hinged with the rotating plate 201c-4 and the U-shaped frame 302a and are used for pushing and pulling the rotating plate 201c-4 through the movement of the U-shaped frame 302 a.

In this embodiment, when the U-shaped frame 302a approaches the worm 301c, the pulling rod 201c-6 pushes the rotating disc to deflect 45 degrees, at this time, since the guide block 201c-3 is located inside the guide groove 201c-5, when the rotating plate 201c-4 deflects, the guide block 201c-3 slides along the guide groove 201c-5, so that the guide block 201c-3 drives the sliding plates 201c-2 to synchronously move, at this time, the two sliding plates 201c-2 move away from each other, at this time, the through hole in the center of the fixed plate 201c-1 is opened, and the air guide pipe 201a is communicated with the inside of the air storage seat 201 b;

Working principle: when the temperature value detected by the temperature controller is greater than or equal to a set temperature threshold value, a control signal is sent to control the electric push rod 302c to extend, at the moment, the electric push rod 302c extends to push the U-shaped frame 302a to approach to one side of the worm 301c, at the moment, the traction rod 201c-6 pushes the rotating disc to deflect 45 degrees, at the moment, because the guide block 201c-3 is positioned in the guide groove 201c-5, when the rotating plate 201c-4 deflects, the guide block 201c-3 slides along the guide groove 201c-5, and then the guide block 201c-3 drives the sliding plate 201c-2 to synchronously move, at the moment, the two sliding plates 201c-2 move back to each other and are far away from each other, at the moment, a through hole in the center of the fixed plate 201c-1 is opened, the air guide pipe 201a is communicated with the inside of the air storage seat 201b, and the air guide pipe 201a is used for guiding a small part of air flow in the volute 103 into the inside the air storage seat 201b, and at the same time, the air flow in the air storage seat 201b is sent into the connecting pipe 203 through a hose, and then enters the inside the heat dissipation ring pipe 202;

when the temperature value detected by the temperature controller is smaller than the temperature threshold value, a control signal is sent to control the electric push rod 302c to shrink, at the moment, the electric push rod 302c drives the U-shaped frame 302a to be far away from the worm 301c, at the moment, the traction rod 201c-6 pulls the rotating disc to reversely deflect 45 degrees, so that the two sliding plates 201c-2 move in opposite directions and are close to each other, at the moment, a through hole in the center of the fixed plate 201c-1 is closed, the air guide pipe 201a is not communicated with the inside of the air storage seat 201b, and at the moment, the heat dissipation operation of the heat dissipation ring pipe 202 is not carried out;

the heat dissipation can be started or stopped by the triggering component 302 according to the temperature condition of the motor outer shell 100, so that the loss of air flow can be reduced when heat dissipation is not needed, and the motor outer shell is convenient to use.
