The water squeezing mechanism structurally mainly comprises a mounting seat 3, wherein a squeezing part 4, a driving part 5 and a linkage part 6 are movably mounted on the mounting seat 3. The wiping device comprises two relatively stable states, namely a first state that the pressing part 4 and the abutting surface 35 on the mounting seat 3 are far away from each other and a second state that the pressing part 4 and the abutting surface 35 on the mounting seat 3 are close to each other, wherein in the second state, the pressing part 4 can press and dewater the wiping object 13 placed in the through opening 36.

The mounting base 3 is adapted to mount the various linkage members or mechanisms, and typically the mounting base 3 may be fixedly or removably mounted to the mop 1 or mop bucket 2. In other embodiments, the mounting base 3 can be the body of the mop bucket 2 or the mop head 11 itself, and is used for positioning and mounting the various linkage components or mechanisms.

In the present embodiment, the mounting seat 3 generally includes two oppositely disposed wall surfaces 34 and an abutting surface 35 located therebetween. An upper wall 341 is integrally formed above the two walls 34 and the abutting surface 35, and a through opening 36 is formed in the middle of the upper wall 341 and is adapted to accommodate the mop 1 to be inserted or withdrawn.
