It should be noted that the outer wall 311 and the second housing 32 match each other. Furthermore, the inner wall 312 is formed by extending inward from a portion of the outer wall 311, and multiple ventilation channels 313 are formed between the inner wall 312 and the outer wall 311. Optionally, four ventilation channels 313 are located at the four corners of the first housing 31 to cooperate with the fan 5 to dissipate heat from the motor.

[0081] like Figure 7 and Figure 12 As shown, in some embodiments, the outer side surface of the outer wall 311 is formed with a first heat dissipation rib 3111. Furthermore, the outer side surface of the inner wall 312 is formed with a second heat dissipation rib 3121. Thus, the provision of the first heat dissipation rib 3111 and the second heat dissipation rib 3121 facilitates heat dissipation from the motor. Optionally, a similar heat dissipation structure is provided on the outer surface of the second housing 32.

[0082] like Figure 3 and Figure 15As shown, in some embodiments, the side of the second housing 32 is provided with a first receiving groove 326. Figure 2 and Figure 12 As shown, the side of the first housing 31 is provided with a second receiving groove 314. It is easy to understand that the upper portion 41 is embedded in the first receiving groove 326, and the lower portion 42 is embedded in the second receiving groove 314. As a result, the surface of the motor becomes smoother and more beautiful.

[0083] Combine Figure 4 、 Figure 9 and Figure 16 , or combined Figure 14 and Figure 17 As shown, in some embodiments, a partition plate 329 is provided in the second shell 32 to separate the upper cavity a and the lower cavity b. Furthermore, the two side edges of the partition plate 329 are recessed downward to form a first groove 3291 and a second groove 3292. It is easy to understand that the motor wire entry hole 322 and the panel wire entry hole 325 pass through the side wall of the first groove 3291, thereby ensuring that the upper cavity a is connected when separated from the lower cavity b. Correspondingly, the first through hole 327 and the second through hole 328 pass through the side wall of the second groove 3292, thereby ensuring that the upper cavity a is connected when separated from the lower cavity b. On the other hand, the back of the bottom of the first groove 3291 and the second groove 3292 is configured as the mounting portion of the sheet metal 7, that is, the sheet metal 7 is connected to the back of the bottom of the first groove 3291 and the second groove 3292 by a plurality of screws.

[0084] It should be noted that, corresponding to the motor line channel 323 provided in the second housing 32 and the motor line channel 323 forming a bulge at the bottom of the second groove 3292, the sheet metal part 7 forms an avoidance hole 71 (such as Figure 12 As shown), the motor wire channel 323 can pass through the avoidance hole 71 and press the sealing gasket 24.

[0085] like Figure 9 and Figure 16 As shown, in some embodiments, the partition plate 329 is provided with a fan cable hole 3293, so that the fan cable of the fan 5 can extend through the fan cable hole 3293 into the upper cavity a and connect to the control board 21. Optionally, the edge of the fan cable hole 3293 is raised upward to facilitate sealing. It should be noted that the fan cable hole 3293 can be sealed by applying a sealant.

[0086] The present invention provides a motor comprising a motor unit, a control unit, and a housing. The motor unit comprises a motor body, the control unit is configured to control the motor body and includes a control board, and the housing comprises a first housing and a second housing arranged sequentially from bottom to top. The first housing is disposed on the outside of the motor body and is open at the top. The second housing has upper and lower openings forming an upper cavity and a lower cavity. The control board is disposed in the upper cavity, and the lower end of the second housing is connected to the first housing to seal the lower cavity and the top of the first housing. Thus, the motor integrates the motor unit and the control unit, making it convenient to use and reducing the occupied space, while achieving a high level of dust and water resistance.

[0087] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
