By providing two tertiary drive gears 3124, the layout of the cleaning drum 2 and the lifting assembly 4 is more reasonable, reducing the footprint of the gear set 312. Of course, the specific transmission level may be set according to actual requirements, and is not limited to this embodiment.

In other embodiments, only one tertiary drive gear 3124 may be provided, with both the first gear 321 and the second gear 3125 meshing with the tertiary drive gear 3124.

In order to improve the aesthetic and safety properties of the cleaning assembly, as shown in fig. 1, a housing 33 is provided at one side of the stand 1, and a gear set 312 is provided in the housing 33 to prevent the gear set 312 from being exposed. Specifically, the housing 33 includes a first housing and a second housing that are detachably connected, and together define an accommodating space for mounting the gear set 312.

Specifically, as shown in fig. 4, the clutch member 32 further includes a clutch shaft 323, and the first gear 321 and the clutch 322 are connected to the clutch shaft 323. The first gear 321 includes a first gear segment 3212 and a second gear segment 3213, and the first helical gear 3211 is located at an end surface of the first gear segment 3212 away from the second gear segment 3213. The second gear segment 3213 is provided with a third tooth which meshes with the tertiary transmission gear 3124 of the driving part 31.

In this embodiment, as shown in fig. 2 and 6, the third tooth is a straight tooth, the driving member 31 is engaged with the third tooth, the clutch 322 is movably disposed on the clutch shaft 323 along the axial direction of the clutch shaft 323, the first gear 321 is rotatably disposed at a set position, and when the driving member 31 drives the first gear 321 to rotate along the second direction, the first helical tooth 3211 presses the second helical tooth 3221, so that the clutch 322 moves in a direction away from the first gear 321, and the first helical tooth 3211 and the second helical tooth 3221 slip. The first helical gear 3211 of the first gear 321 may press the second helical gear 3221 of the clutch 322 to move, so that the first helical gear 3211 and the second helical gear 3221 slip with each other, so that the first helical gear 3211 cannot provide driving force for the second helical gear 3221.

Note that, the first gear 321 is rotatably disposed at the set position means that: the first gear 321 can only rotate on the rotating clutch shaft 323, but cannot rotate along the axis of the clutch shaft 323.

Specifically, the first gear segment 3212 and the second gear segment 3213 are each cylindrical, and the diameter of the second gear segment 3213 is larger than the diameter of the first gear segment 3212.

In another embodiment, the third teeth are helical teeth, the driving member 31 is engaged with the third teeth, the first gear 321 is movably disposed on the clutch shaft 323 along the axial direction of the clutch shaft 323, the clutch 322 is rotatably disposed at a set position, and when the driving member 31 drives the first gear 321 to rotate along the second direction, the first gear 321 moves away from the clutch 322 to separate the first helical teeth 3211 from the second helical teeth 3221, and the third transmission gear 3124 is also helical gear (not shown in the drawings), so that the third teeth and the third transmission gear 3124 are helical teeth engaged. Because the three-stage transmission gear 3124 is a helical gear, the helical gear can provide forces in two directions for the first gear 321, so that the first gear 321 can rotate and move synchronously, when the three-stage transmission gear 3124 drives the first gear 321 to rotate along the first direction, the first gear 321 moves towards the clutch 322, and when the first helical tooth 3211 and the second helical tooth 3221 are engaged, the clutch 322 limits the first gear 321, at this time, the first gear 321 does not move any more, and the first gear 321 only drives the clutch 322 to rotate. When the three-stage transmission gear 3124 drives the first gear 321 to rotate in the second direction, the first gear 321 moves in a direction away from the clutch 322 by the helical teeth to disengage the first gear 321 from the clutch 322, and the first gear 321 does not provide a driving force to the clutch 322.

When the first gear 321 rotates in the first direction, the second helical teeth 3221 of the clutch 322 always abuts against the first helical teeth 3211 under the elastic force of the elastic member 413, so as to improve the transmission effect between the first gear 321 and the clutch 322.

Alternatively, the transmission groove 4121 has a regular hexagonal cross section.
