In this way, the mounting plate 413 has a better heat radiation protection capability, and thus the risk of heat radiation caused by long-time operation of the motor 31 to melt and fire the motor terminals 32 can be further effectively prevented.

In some embodiments, the side of the motor terminal 32 is formed with a first clamping structure 321. The first clamping structure 321 is provided with a mounting groove 322. The mounting plate 413 is partially inserted in the mounting groove 322. In this way, the mounting plate 413 is partially inserted into the mounting groove 322 in such a manner that the mounting stability of the motor terminal 32 can be improved.

In some embodiments, the mounting plate 413 is provided with a first wire slot 414 through which the wire harness 33 passes. The wire harness 33 may be bent through the first wire slot 414 to extend out of the box structure 40. The first wire guide groove 414 can function to fix the wire harness 33.

In some embodiments, the number of mounting plates 413 is two. The two mounting plates 413 are disposed in spaced opposition. A second wire groove 415 through which the wire harness 33 passes is formed between the two mounting plates 413. The provision of the second wire guide slot 415 facilitates threading of the wire harness 33 through the box structure 40. The provision of two mounting plates 413 provides for better expansion of the cartridge structure 40. The two motor terminals 32 can be respectively on the two mounting plates 413.

In the present embodiment, the wire harness 33 includes a first wire harness 331 and a second wire harness 332. The mounting plate 413 is provided with a first wire slot 414 through which the first wire harness 331 passes. The first wire groove 414 is a U-shaped guide groove with one side open. The first wire harness 331 passes through the first wire groove 414, and a portion of the first wire harness 331 is stuck with the first wire groove 414. A second wire groove 415 through which the second wire harness 332 passes is formed between the two mounting plates 413. Thus, the first wire harness 331 and the second wire harness 332 are separately provided, so that winding can be avoided. Wherein the first wire harness 331 may be a live wire and the second wire harness 332 may be a neutral wire.

In some embodiments, the bracket 41 is removably coupled to the cover 42 via a back-off structure 410. Thus, the connection mode of the bracket 41 and the cover body 42 is simpler, and the installation and the disassembly are convenient.

In the present embodiment, the number of mounting plates 413 is two. Each mounting plate 413 is provided with an inclined first clamping groove 416. The first connection plate 411 is provided with an inclined second clamping groove 417. The cover 42 includes a third connecting plate 421, a fourth connecting plate 422, and a fifth connecting plate 423.
