Referring to fig. 2 to 4 and 12 to 14, the wringing mechanism of this embodiment is mainly suitable for squeezing and dewatering a mop with a mop.

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 mop 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, and in the second state, the pressing part 4 can press and dewater the wiper 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opening 36 is formed in the middle of the upper wall 341 and is adapted to accommodate the mop 1 to be inserted or withdrawn. When the wringing mechanism is installed in the mop bucket 2, the upper wall 341 may be at least a portion of the bung of the mop bucket 2; the upper wall 341 may be a connecting ring surface for connecting two oppositely disposed walls and the abutting surface 35 between the two walls when the wringing mechanism is mounted to the mop 1. In other embodiments, a left end face opposite to the abutting face 35 is further provided, and the left end face may be hollowed or provided with an opening structure, so as to guide the squeezed water squeezed from the mop to other positions, such as the inside of the mop bucket 2.

In actual production, the front wall surface and the rear wall surface are in a thin plate shape, and in order to ensure the weighing strength, a plurality of reinforcing ribs 344 which are distributed transversely and vertically can be arranged on the surfaces of the front wall surface and the rear wall surface. The outer contour shapes of the front wall surface and the rear wall surface can adapt to a mop or a mop bucket or other devices for installing the water squeezing mechanism, and the water squeezing mechanism is adaptively arranged to be rectangular or other adaptive special-shaped sections.

The upper wall 341 defines a cross-sectional shape of the opening 36 generally corresponding to the shape of a mop head, and includes a first region 361 corresponding to a wipe and a second region 362 corresponding to a mop pole, which are in communication. The abutment surface 35 acts as an intermediate section that partially divides the two regions, due to the contraction of the second zone 362 relative to the cross-sectional width of the first zone 361. When the wringing mechanism is used for cleaning the mop, one side of the mop where the mounting plate for mounting the wiping material is located is abutted against the abutting surface 35, so that the stress and the moving direction of the mop when the mop is pulled upwards for wringing water are kept.

In other embodiments, a slot or slot is provided in the middle region of the front and rear walls for receiving a cleaning brush.

In order to adapt to the usage habit of the user, the abutment surface 35 is here arranged vertically. In other embodiments, the abutting surface 35 may be adjusted to be inclined or another angle depending on the direction of the driving portion 5. In other embodiments, the abutting surface 35 may not be planar, but may be configured as a roller or a bump, for example, which can perform the abutting function, and only the retaining drum or the bump can bear the transverse force of the mop head to maintain the abutting function with the pressing structure.

A group of sliding grooves are correspondingly arranged on the front wall surface and the rear wall surface of the two sides of the mounting seat 3 in the width direction, and the sliding grooves are suitable for movably mounting an extrusion part and are extrusion part sliding grooves 31. Here, the squeezing portion chute 31 is provided in an inclined strip groove.

Here, the driving portion chute 33 is provided in a vertical strip-shaped groove. The upper ends of the pressing portion link 31 and the driving portion link 33 are substantially equal in height, and the upper ends of the pressing portion link 31 and the driving portion link 33 are closer to the lower ends of the pressing portion link 31 and the driving portion link 33. In other embodiments, the direction and shape of the pressing portion sliding slot 31 and the driving portion sliding slot 33 may also be arranged in other manners, such as in a figure of eight, or in a non-linear shape such as an arc shape. The upper ends of the two parts are close to each other, and the squeezing part is suitable for being in the second state to squeeze and dewater.

The linkage part 6 is respectively connected with or abutted against the driving part 5 and the extrusion part 4 and is suitable for linking the driving part 5 and the extrusion part 4, so that the driving part 5 and the extrusion part 4 are close to or far away from each other, and the directions of motion components of the driving part 5 and the extrusion part 4 in the vertical direction are always opposite. In this embodiment, the linkage portion 6 is in a rocker shape, can rotate relative to the mounting base 3, and includes a rotation fulcrum 63 and linkage arms on two sides. The interlocking section 6 includes a pair of interlocking sections 6 having a substantially "√" shape, and are symmetrically provided on the front and rear wall surfaces, respectively. The linkage portion 6 includes a driving portion linkage arm 61, a pressing portion linkage arm 62, and a fulcrum 63.

In the intermediate region between the pressing portion chute 31 and the driving portion chute 33, a fulcrum 63 is provided. The fulcrum 63 is adapted to fix the interlocking part 6 such that the interlocking part 6 can reciprocate rotationally up and down with the fulcrum 63. In the present embodiment, the fulcrum 63 is provided closer to the pressing portion 4 at a position of about 2/3 therebetween. The fulcrum 63 includes a fulcrum hole 631 provided in the linkage portion 6 and a fulcrum shaft 632 provided in the mounting base 3, the fulcrum shaft 632 is a rotating shaft, and the linkage portion 6 is rotatably mounted on the fulcrum shaft 632 through the fulcrum hole 631. In another embodiment, the linking part 6 and the mounting base 3 may be provided with a fulcrum hole 631, respectively, and the fulcrum shaft 632 may be provided as a fulcrum.

In order to save and optimize the size of the water squeezing mechanism and adjust the relationship of the arm lengths, the arm length of the linkage arm 61 of the driving part is larger than that of the linkage arm 62 of the squeezing part, and by utilizing the lever principle, when the linkage part 6 rotates around a fulcrum, the displacement distance of the squeezing part 4 is smaller than that of the squeezing part 4, so that the mounting seat 3 is simple in structure and proper in size.

Furthermore, in order to conveniently replace the linkage part 6, the linkage part 6 is connected with the mounting base 3 in an inserting and matching manner by adopting a quick-release structure. In order to prevent the fulcrum shaft 632 from easily and randomly coming off from the fulcrum hole 631 due to the detachable connection, a limit portion 633 is disposed on the fulcrum hole 631 and the fulcrum shaft 632.
