[0077] A water inlet 29 connected to the clean water area 5 is provided at the junction of the side wall of the boss 28 and the upper surface of the wheel cover 17 . Clean water in the clean water area 5 enters the boss 28 from the water inlet 29 and then enters the pumping space 18 from the through hole 25 .

[0078] Preferably, a plurality of convex ribs 37 are evenly provided around the circumference of the axle 13, and the axle 13 is supported by the circumferential convex ribs 37 abutting against the inner wall of the positioning hole 14. The contact between the convex ribs 37 and the positioning bracket can reduce the contact area between the axle 13 and the positioning bracket, thereby reducing the friction resistance during rotation.

[0079] The above is an introduction to the anti-sway mop bucket pumping structure provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
