[0009] The utility model provides a water guide platform sunken relative to the upper surface of the base at the top edge of the return water area, and the water guide platform protrudes inward to form a convex clamp, which presses the edge of the filter plate downward, so that the filter plate is tightly matched with the base at all locations. At the same time, the sunken water guide platform can quickly guide water flow and residue to the filter plate, thereby avoiding the residue jamming problem, which is beneficial to improving the overall filtering capacity and cleaning power of the cleaning machine.

[0010] Preferably, the water guide platform gradually slopes downward from its outer edge to the edge of the water return area to form a first slope. This structure is conducive to improving the water and slag guiding performance of the water guide platform. At the same time, when the filter plate is assembled downward, the first slope can play a guiding role to facilitate assembly.

[0011] Preferably, the first inclined surface constitutes the upper surface of the convex card, and the lower part of the convex card forms a second inclined surface which gradually slopes from the filter plate to the inner wall of the water return area from top to bottom. The second inclined surface has a diversion effect on the one hand, and on the other hand, it can play a good guiding role when the filter plate is removed to avoid the convex card from being squeezed and damaged.

This structure is conducive to further improving the diversion effect.

[0015] Preferably, the water return area and the filter plate are both formed into a triangular structure with rounded corners, and the guide groove is provided at the rounded corner of the triangular structure. The guide groove can also be provided on the straight side of the triangular structure to improve the guide effect.

[0016] Preferably, the area enclosed by the inner edge of the convex card is larger than the area enclosed by the outer edge of the filter plate. Such a structure is adopted to ensure that the convex card can press the filter plate tightly on the base at all places, improve the compactness and reliability of the assembly, and avoid the filter plate from partially warping.

[0017] Preferably, the water return area and the filter plate are both formed into a triangular structure with rounded corners, and the filter plate is fastened to the base by at least three screws, wherein the three screws are arranged near the middle of each straight side of the triangular structure. This structure facilitates the assembly reliability of the filter plate and the base.

Such a structure is adopted to ensure that the convex clamp 13 can press the filter plate 2 on the base 1 at all places, improve the compactness and reliability of the assembly, and avoid the filter plate from partially warping.

[0027] The water guide platform 12 gradually slopes downward from its outer edge to the edge of the water return area 11 to form a first slope 121. This structure is conducive to improving the water and slag guiding performance of the water guide platform 12. At the same time, when the filter plate 2 is assembled downward, the first slope 121 can play a guiding role to facilitate assembly.

[0028] The first inclined surface 121 constitutes the upper surface of the convex card 13, and the lower part of the convex card 13 forms a second inclined surface 131 which gradually slopes from the filter plate 2 to the inner wall of the return water area 11 from top to bottom. The second inclined surface 131 has a diversion effect on one hand, and on the other hand, it can play a good guiding role when the filter plate 2 is removed to avoid the convex card from being squeezed and damaged.

[0029] The upper surface of the base 1 is also provided with a third inclined surface 14 arranged around the periphery of the water guide platform 12 and gradually inclined inward from the outer edge to the inner edge, and the width of the third inclined surface 14 is greater than the width of the first inclined surface 121. The inclination of the third inclined surface 14 is greater than the inclination of the first inclined surface 121. The third inclined surface 14 can further improve the water and slag guiding effects.

[0030] The water guide platform 12 is provided with a guide groove 15 which partially penetrates the convex card 13 from top to bottom. The guide groove 15 can separate the first inclined surface 121, the second inclined surface 131 and part of the third inclined surface 14, which is conducive to the rapid reflux of residues or residual water.

[0031] The middle of the third slope 14 extending from the outer end of the guide groove 15 is formed with a fourth slope 151 which gradually slopes downward from the middle of the third slope 14 to the outer edge of the water guide platform 12. This structure is conducive to further improving the diversion effect.

[0032] The water return area 11 and the filter plate 2 are both formed into a triangular structure with rounded corners, and each rounded corner of the triangular structure is provided with a guide groove 15. The guide groove 15 can also be provided on the straight side of the triangular structure to improve the guide effect.

[0033] The filter plate 2 is fastened to the base 1 by three screws, wherein the three screws are arranged near the middle of each straight side of the triangular structure. This structure facilitates the assembly reliability of the filter plate and the base.

[0034] The cleaning machine of this embodiment includes an inner tank and the above-mentioned base assembly. The bottom of the inner tank is open and inserted on the base so as to enclose a washing chamber together with the base.

[0035] In this embodiment, a water guide platform 12 is provided at the top edge of the return water area 11, which is sunken relative to the upper surface of the base 1, and the water guide platform 12 protrudes inward to form a convex clamp 13. The convex clamp 13 presses the edge of the filter plate 2 downward, so that the filter plate 2 is tightly matched with the base 1 at all places. At the same time, the sunken water guide platform 12 can quickly guide the water flow and residue to the filter plate 2, thereby avoiding the residue jamming problem, which is beneficial to improving the overall filtering ability and cleaning power of the cleaning machine.
