[0029] Further, the sliding groove corresponding to the movement track of the sliding block 45 is formed in the inner side of the motor shell 1, and the sliding block 45 is slidably connected in the sliding groove. By forming the sliding groove, the sliding block 45 can rotate in the inner side of the motor shell 1, and the rotating blade 44 is limited, so that the rotating blade 44 is more stable during rotation.

[0030] Further, the circular groove corresponding to the movement track of the supporting member 47 is formed at the bottom of the motor shell 1, and the supporting member 47 is slidably connected in the circular groove. By forming the circular groove, the supporting member 47 can rotate at the bottom of the motor shell 1, and the supporting member 47 can support the cleaning brush 41, so that the cleaning brush 41 is more stable during rotation.

[0032] Embodiment two

[0033] Please refer to Figures 1-5 And on the basis of embodiment one, further obtain that the mounting mechanism 3 includes hollow disc 34, the hollow disc 34 is slidably connected on the periphery of the rotating shaft 2, the sliding block 32 is fixedly connected to the inner side of the hollow disc 34, the propeller 33 is fixedly connected to the outer side of the hollow disc 34, and the limiting bolt 31 is screw-connected to the inner side of the hollow disc 34.

[0034] Further, the rotating shaft 2 is internally provided with a circular hole corresponding to the position of the limiting bolt 31, and the limiting bolt 31 is threadedly connected to the inside of the circular hole.
