The working principle of the wringing and wringing assembly of the mop dewatering assembly of the present invention is described as follows:

the wringing and pressing basket 3 and the squeezing basket 2 with the mop dehydration combined structure can be respectively and independently arranged in the mop bucket 1 for use, and the wringing and pressing basket comprises the following specific components: 1. when the twisting and pressing basket 3 is used independently, the pivoting structure 9 on the twisting and pressing basket 3 is arranged between the twisting and pressing basket 3 and the mop barrel 1, namely, the hemp shaft 18 is fixed in the mop barrel 1, the twisting and pressing bottom plate 7 is provided with the driving hole 19, a mop head is placed in the twisting and pressing basket 3 and is squeezed downwards with force, the squeezing force is acted on the twisting and pressing bottom plate 7, so that the twisting and pressing bottom plate 7 moves downwards along the axial direction, the twisting and pressing plate 8 stretches downwards to generate deformation, in the process, the hemp shaft 18 on the twisting and pressing bottom plate 7 is driven to rotate by the driving hole 19 when moving downwards along the axial direction, so that the twisting and pressing bottom plate 7 generates circumferential motion, and then the plurality of twisting and pressing plates 8 are driven to have circumferential motion, because the short deformation plate 10 of the twisting and pressing basket edge 6 of the twisting and pressing plate 8 are fixedly connected, the long deformation plate 11 and the circumferential plate 12 can only inwardly generate deformation, and accordingly the mop head in the twisting and pressing basket 3 is squeezed, the purpose of dehydration is achieved. 2. When extrusion basket 2 independent use, then the mop head gets into the accommodation space who extrudees basket 2, and the mop head at this moment supports and presses at extrusion bottom plate 20, and we can push up whole mop head downwards hard, and the mop head moves down, and receives the extruded extrusion bottom plate 20 of mop head and move down to drive stripper plate 22 and stretch, the condition that stripper plate 22 was stretched at this moment is: the long plate 23 is pulled downwards by the extrusion bottom plate 20, the short plate 24 is pulled by the long plate 23, the lower arc between the extrusion bottom plate 20 and the long plate 23 crosses the transition plate 15, the fillet 13 between the long plate 9 and the short plate 24, and the upper arc between the short plate 24 and the extrusion basket edge 21 crosses the transition plate 14, which is equivalent to a hinge, so that the short plate 24 turns over relative to the extrusion basket edge 21, the long plate 23 turns over relative to the short plate 24, and the long plate 23 turns over relative to the extrusion bottom plate 20, because the included angle between the long plate 23 and the short plate 24 is an acute angle, and the included angle between the short plate 24 and the extrusion basket edge 21 is an acute angle, and the included angle between the long plate 23 and the extrusion bottom plate 20 is an obtuse angle, the long plate 23 turns inwards relative to the extrusion bottom plate 20, thereby reducing the accommodation space, thereby extruding the mop head in the accommodation space, and achieving the purpose of dewatering.

The wringing basket 3 and the squeezing basket 2 can also be combined for use to form a wringing component, when in use, a mop head is arranged in the wringing basket 3, the wringing basket 3 is squeezed downwards by force, the wringing bottom plate 7 moves downwards and is pressed against the squeezing bottom plate 20 of the squeezing basket 2, then the squeezing bottom plate 20 synchronously moves downwards, so that the wringing pressing plate 8 of the wringing basket 3 deforms inwards, the squeezing plate 22 of the squeezing basket 2 deforms inwards, and therefore the wringing pressing plate 8 has squeezing and wringing effects on a mop head, and the squeezing plate 22 has further squeezing effect on the mop head, and the purpose of dewatering is achieved.

The twisting and pressing basket 3 and the squeezing basket 2 under the combined condition, wherein, the twist shaft 18 related to the twisting and pressing basket 3 can be fixed on the twisting and pressing bottom plate 7 or the mop bucket 1, and the driving holes 19 are respectively arranged on the flange seat 16 and the twisting and pressing bottom plate 7 correspondingly.

The design of the flange seat 16 allows for greater space utilization within the mop bucket 1, while the design without the flange seat 16 may reduce manufacturing costs somewhat, but it may take up space within the mop bucket 1 to allow for the mating of the knurled shaft 18 with the drive aperture 19.
