A filter screen and filter screen assembly structure for a floor scrubber

Abstract

This utility model relates to a filter screen and its assembly structure for a floor scrubber. The filter screen includes a screen frame with multiple filtration areas, each containing a filter screen. One side of the screen frame is cylindrical, while the opposite side is flat. The cylindrical structure extends outwards on both sides, forming a pair of first protrusions. A pair of second protrusions are located on each side of the screen frame near the first protrusions. Compared to existing technologies, the filter screen provided by this utility model features a cylindrical screen frame on one side and a flat frame on the other, along with the positioning design of the first and second protrusions. This allows for precise matching with the floor scrubber, significantly reducing installation difficulty and minimizing loosening and jamming during assembly. The embedded groove and handle design in the center of the flat frame facilitate quick disassembly and maintenance, improving ease of use.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] (1) This utility model provides a filter screen for a floor scrubber. The filter screen has a cylindrical structure on one side and a flat plate structure on the other side. With the positioning design of the first protrusion and the second protrusion, it can be precisely matched with the main unit of the floor scrubber, which significantly reduces the difficulty of installation and reduces loosening and jamming during assembly.

The screen frame of the filter screen is injection molded in one piece, which eliminates the strength defects of spliced ​​design, improves the overall structural rigidity, extends service life, avoids dirt accumulation at the joints, reduces cleaning dead corners, and facilitates daily maintenance. It is also easy to assemble with the floor scrubber, reduces equipment damage caused by assembly errors, indirectly extends the service life of the entire floor scrubber, and reduces user operating costs.

[0026] (5) This utility model provides a filter screen assembly structure. In this assembly structure, the filter screen is rotated by the first protrusion and the first mounting hole of the filter bracket, so that the filter screen can be opened and closed flexibly relative to the filter bracket. The opening action can be achieved without complete disassembly, which is convenient for users to operate quickly. When closed, the second protrusion is embedded in the second mounting hole, and the filter screen and the filter bracket are accurately fixed by the mechanical fastening structure. This can effectively prevent the filter screen from being accidentally loosened or opened when the floor scrubber is working, ensure the sealing and stability of the filter assembly, and ensure that the filtration function is normal.

[0039] The mesh frame 1 has a cylindrical structure on one side and a flat structure on the other opposite side;

[0040] The cylindrical structure extends outward on both sides, forming a pair of first protrusions 3;

[0041] The mesh frame 1 has a pair of second protrusions 4 on each of its two sides near the pair of first protrusions 3. When the filter mesh is fixed to the floor scrubber, the cylindrical side of the mesh frame 1 is abutted against the corresponding floor scrubber assembly position, and then the flat side is abutted against the corresponding floor scrubber assembly position.

[0042] In this embodiment, the flat plate structure has an embedding groove 5 in the middle and a handle 6 above the embedding groove 5. The embedding groove 5 and the corresponding assembly part of the floor scrubber form a complementary interlocking structure. During assembly, the protruding part of the floor scrubber will be embedded in the groove. The physical interlocking relationship restricts the lateral and longitudinal displacement of the mesh frame 1 in the plane, thereby enhancing the assembly stability.

[0043] In this embodiment, both the first protrusion 3 and the second protrusion 4 have a pair of horizontally arranged sides, which are perpendicular to the mesh frame 1, so as to engage with the assembly position corresponding to the floor scrubber, restrict the lateral and longitudinal displacement of the mesh frame 1 in the plane, and thus enhance the assembly stability.

[0044] In this embodiment, the mesh frame 1 is provided with multiple filtration areas, and each filtration area is provided with a filter screen 2.

[0045] In this embodiment, the filtering area is evenly distributed with through holes, which are one or more of round holes, square holes, or diamond-shaped holes. Specifically, when the through hole is round, its diameter is 1–1.5 mm; when the through hole is square, its side length is 1–1.5 mm; and when the through hole is diamond-shaped, its side length is 1–1.5 mm.

[0046] In this embodiment, the planar deformation of the mesh frame 1 is greater than -0.5mm and less than 0.5mm, which can ensure the sealing performance with the sealing component and prevent water and slag leakage.

[0047] In this embodiment, the mesh frame 1 is an injection-molded one-piece structure, which eliminates the strength defects of spliced ​​design, improves the overall structural rigidity, extends service life, avoids dirt accumulation at the joints, reduces cleaning dead corners, and facilitates daily maintenance; it also facilitates assembly with the floor scrubber, reduces equipment wear caused by assembly errors, indirectly extends the service life of the entire floor scrubber, and reduces user operating costs.

[0050] The filter support 7 is provided with a pair of first mounting holes 8 and a pair of second mounting holes 8; the pair of first protrusions 3 are respectively inserted into the pair of first mounting holes 8, so that the filter screen can rotate relative to the filter support 7;

[0051] When the filter screen plate and the filter bracket 7 are closed, the second protrusion 4 is embedded in the second mounting hole 9. When the filter screen plate and the filter bracket 7 are opened and closed, the second protrusion 4 is disengaged from the second mounting hole 9.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
