[0028] Reference Figure 2 , Figure 4 and Figure 6 The cleaning component includes a micro motor 13, which is arranged on the upper part of the mounting shell 11. The output end of the micro motor 13 is fixedly connected to a rotating rod 14, the outside of the rotating rod 14 is fixedly connected to a turntable 15, the outside of the turntable 15 is fixedly connected to a connecting plate 16, the outside of the connecting plate 16 is fixedly connected to a mounting block 17, both sides of the mounting block 17 are fixedly connected to a second spring 19, the outside of the second spring 19 is fixedly connected to a cleaning brush 18, the cleaning brush 18 is slidably connected to the inside of the mounting block 17, the upper part of the mounting shell 11 is fixedly connected to a bracket 12, and the micro motor 13 is fixedly connected to the inside of the bracket 12.

[0029] By setting up the bracket 12, it is convenient to fix the micro motor 13. By starting the micro motor 13, the turntable 15 fixed on the outside of the rotating rod 14 rotates. The rotation of the turntable 15 causes the mounting block 17 fixed on the outside of the external connecting plate 16 to move.
