Description

Technical Field

[0001] The utility model relates to the field of filter structures, in particular to a gear rack slider device. Background Art

[0002] After the existing pre-filter has been working for a long time, the impurities carried in the raw water are embedded in the mesh of the filter element, which easily causes the filter element to be blocked, so the filter element needs to be removed and replaced regularly. However, the replacement of the filter element in the existing pre-filter is relatively cumbersome, and the filter element needs to be removed from the inside of the pre-filter with tools. Therefore, it is necessary to design a linkage structure that is convenient for disassembly and assembly of the filter element, and during the disassembly process, it is necessary to ensure that the linkage structure runs smoothly and labor-saving.
