[0039] Specific as Figure 6 As shown, the second boss 64 is spaced apart from the snap-in flange 6, so that the second boss 64 can be pressed, so that the common method of relative pulling out of the hand-held mite removal brush interface 1 and the connector 5 through friction is replaced by pulling out the connector 5 by pressing the wedge-shaped surface formed by the internal pressure of the second boss 64, making the disassembly and assembly of the two more labor-saving.

[0040] A partition 82 is provided in the second wire cavity 81, so that the wires can be classified and passed through a plurality of second wire cavities 81 separated by the partition 82, so that the wiring is clearer and it is convenient for assembling the connector 5 on the mite removal brush interface 1 and inspecting the wires.

[0041] A stepped clamping ring 32 is provided at the outer end of the inner interface 3, and the clamping inner rib 8 is spliced ​​and clamped on the stepped clamping ring 32. A sealing ring can be provided here to ensure the isolation of the dust collecting chamber 31 from the mite removal brush interface 1 and the internal structure of the joint 5.

[0042] The assembly process of the mite removal brush and the joint connection structure which is convenient for disassembly, assembly and replacement in this embodiment includes: in one embodiment, Figure 3 , 4 , first lead the wire out of the first wire cavity 71 and connect it to the mite removal brush drive system (negative pressure fan, roller brush drive motor), hold the external interface 2 with one hand, and press the clamping block 61 with the other hand to retract the clamping flange 6 and press it into the installation cavity 21, rotate the joint 5 appropriately to align the wire box 7 with the first notch 22, and then press it in so that the wire box 7 abuts against the first notch 22, the stepped clamping ring 32 cooperates with the sealing ring and the clamping inner rib 8 to seal the dust collection cavity 31, the clamping block 61 is clamped on the bayonet 24 to complete the shaping and assembly, and then the wire in the wire box 7 is straightened; in another embodiment, as Figure 5 The wire is led out from the second wire cavity 81 to connect the internal wiring of the mite removal brush, and the second boss 64 is pressed according to the above steps to complete the assembly of the connector 5, the first boss 63 is in contact with the first notch 22, and the second boss 64 is positioned with the second notch 23; in another embodiment, Figure 6The wires should be classified and led out into a plurality of second wire cavities 81 separated by partitions 82 and connected.

[0043] In summary, due to the adoption of the above technical solution, the mite removal brush and connector connection structure of this embodiment, which is easy to disassemble, assemble and replace, has the following beneficial effects compared with the prior art:

[0044] 1. The mite removal brush and connector connection structure uses the internal and external interfaces on the mite removal brush to cooperate with the connector's snap-in flange and snap-in inner ribs for multi-layer snap-in positioning, which can adapt to the stable disassembly and use of a variety of connectors, and at the same time achieve the separation of the dust collecting chamber and the installation chamber for wire laying at the connection between the two, thereby ensuring the isolation of the dust collecting chamber and other parts of the external mite removal brush, the tidy use of the mite removal brush, and the convenience of wire laying, thereby improving the convenience of disassembly, assembly and replacement of the mite removal brush and connector.

[0045] 2. The second boss is spaced apart from the snap-on flange, so that the second boss can be pressed, so that the common handheld mite removal brush interface and joint are pulled out relative to each other through friction, which is replaced by pulling out the joint by pressing the wedge-shaped surface formed by the internal pressure of the second boss, making the disassembly and replacement of the two more labor-saving.
