[0008] Furthermore, the ventilation holes are evenly arranged on the inner wall of the motor housing body, and the positions thereof correspond to the periphery of the rotating shaft.

[0009] Furthermore, the through-notch is arranged at the center of the surface of the mesh cover, and the mesh cover passes through the rotating shaft through the through-notch.

[0010] Furthermore, the fixing blocks are all connected to the motor housing body via rotation damping.

[0011] Furthermore, the mesh cover is made of stainless steel, and the mesh cover is fixed to one side of the air hole through a fixing block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By providing a mesh cover and a through-notch, the through-notch is used to allow the mesh cover to pass through the periphery of the rotating shaft, and the mesh cover is used to cover the vent hole to block foreign matter, thereby preventing foreign matter from entering the housing and affecting the motor.

[0014] By setting a fixed block and a rotation damper, the mesh cover is positioned and fixed by using the fixed block of the positioning assembly, and the rotation damper is used to cooperate with the fixed block to rotate, so that personnel can disassemble and assemble the mesh cover later.
