When the mop head rotates, the elastic driving member can give a certain reverse pressure (damping) to the driving member, so that the movement of the driving member under the action of centrifugal force is more uniform, and the situation that the driving member moves to the end all at once can be avoided.

In this embodiment, the elastic driving member is a helical compression spring.

The structure of the driving part is shown in Figures 18 and 19: the main body of the driving part is a plastic part, and a metal counterweight 55 is embedded inside; The frictional force of the drive when it moves.

Example 4:

The difference between this embodiment and Embodiment 1 lies in the partial structure of the mop bucket and the structure of the mop used together;

As shown in Fig. 20 to Fig. 22: the mop bucket includes a bucket body 67, and the bucket body has a partition plate 671 that divides its inner cavity into the clean water area and the sewage area, and the clean water area is A detachably connected cover plate 69 is arranged above the cover plate, above the cover plate is the working area, the cover plate only covers the clean water area, so the working area can communicate with the sewage area;

The mop used in this embodiment is the mop in Embodiment 3, and the cleaning member is a cleaning brush 68, and the cleaning brush is fixedly connected to the bottom of the working area.

The cleaning piece of the present invention can adopt various cleaning components known in the prior art, including cleaning scrapers, cleaning brushes, cleaning sticks, etc. The cleaning scrapers are plate-shaped or block-shaped protrusions.

In addition, the water outlet 76 of the suction pump in this embodiment (the outlet for spraying water to the mop) is also different from that in Embodiment 1. The water outlet in Embodiment 1 is only a through hole, and the water outlet in this embodiment is set to There is a guide structure for guiding the water, and the direction of water spray is adjusted through the guide structure, so that it can better spray (clean) the mop.
