[0040] Referring to Figure 7 , Figure 8 and Figure 9 , the cleaning piece 10 comprises a circular positioning block 101, the top of the circular positioning block 101 is rotationally connected with the middle of the bottom of the positioning frame 6, the left and right sides of the circular positioning block 101 are both fixedly installed with a strip-shaped block 102, the top of each strip-shaped block 102 is provided with a groove 104, the inside of each groove 104 is fixedly installed with a squeezing spring 105, the top of each squeezing spring 105 is fixedly installed with a cleaning brush 103, the outer surfaces of the two cleaning brushes 103 are slidingly connected with the inner walls of the grooves 104, the top of the circular positioning block 101 is fixedly installed with a connecting rod 106, and the bottom of the connecting rod 106 penetrates through the positioning frame 6 and is used in cooperation with the driving motor 7.

[0041] The above solution is adopted: the power source for the entire cleaning component 10 is achieved by energizing the drive motor 7. Since force can be transmitted, the drive motor 7 rotates while driving the connecting rod 106 to rotate. The connecting rod 106 rotates while driving the circular positioning block 101 to rotate. The circular positioning block 101 rotates while driving the strip block 102 to rotate. At the same time, the top of the cleaning brush 103 is in contact with the bottom of the protective net 9, and a deformation force is applied to the compression spring 105.

An annular protrusion 173 is fixedly installed inside the circular through hole 172, and the end of the annular protrusion 173 away from the circular through hole 172 is used in conjunction with the interior of the rotating rod 16.

[0047] The above solution involves rotating the rod 16 inside the circular through hole 172, and using the annular protrusion 173 in conjunction with the inside of the rotating rod 16 to improve the rotation effect of the rotating rod 16. Finally, the square block 171 is used to support the rotating rod 16, making the rotation process of the rotating rod 16 more stable.
