Description

Technical Field

[0001] The utility model relates to the technical field of filter top covers, in particular to a quick-detachable filter top cover locking and opening mechanism. Background Art

[0002] Cartridge filters are a more sophisticated filter, effectively removing suspended solids, colloids, and some organic matter from water. They are primarily suitable for filtering beverages, domestic water, ultrapure water equipment security systems, oilfield injection water, chemical solutions, electroplating solutions, and other liquids used in the electronics, petroleum, chemical, pharmaceutical, and food industries. Cartridge filters generally require regular disassembly, cleaning, and replacement of the filter element—the filter element—to maintain filter efficiency. Failure to do so can significantly reduce water purification performance over time.

[0021] See also Figure 1-4 , a quick-detachable filter top cover locking and opening mechanism, including a filter top plate 1 and a fixed top cover 2, the top of the filter top plate 1 is provided with a stabilizing through hole, the inside of the stabilizing through hole is fixedly connected to a stabilizing sleeve 3, the bottom end of the stabilizing sleeve 3 is fixedly connected to two connecting blocks 4, a filter element replacement pipe 5 is fixedly connected between the two connecting blocks 4, a threaded groove is provided on the inner wall of the filter element replacement pipe 5, a threaded rod 6 is screwed inside the threaded groove, and a torsion block 7 is fixedly connected to the top of the threaded rod, an annular groove is provided inside the stabilizing sleeve 3, and a limiting through groove is provided at the top of the annular groove, and two limiting rods 8 are fixedly connected to the bottom end of the fixed top cover 2, and the bottom ends of the two limiting rods 8 are fixed It is fixedly connected with a limiting block 9, one end of the two limiting blocks 9 is in contact with the inner wall of the annular groove respectively, and the bottom end of the fixed top cover 2 is fixedly connected with a circular sealing sponge 10. By rotating the fixed top cover 2, the two limiting blocks 9 are moved inside the annular groove until the two limiting blocks 9 are parallel to the two limiting through grooves, thereby realizing that the fixed top cover 2 can be freely moved and disassembled. After the threaded rod 6 is disassembled by rotating the torsion block 7, the filter element replacement pipe 5 is opened, and the filter element inside the filter is replaced through the filter element replacement pipe 5, and the interior of the filter can be checked more conveniently, thereby improving the maintenance efficiency of the filter.

[0022] Preferably, a plurality of stabilizing springs 11 are fixedly installed at the bottom end of the annular groove, and an annular slider 12 is fixedly installed between the top ends of the plurality of stabilizing springs 11. Under the tension of the plurality of stabilizing springs 11, the annular slider 12 is driven to move and push the limiting block 9 into the inside of the limiting groove. After subsequent pulling, the fixed top cover 2 can be freely moved and disassembled. The top end of the torsion block 7 is fixedly connected to a torsion plate 13, and the top end of the fixed top cover 2 is fixedly connected to a torsion handle 14, which makes it more convenient to rotate the torsion block 7 and the fixed top cover 2.
