[0032] The filter tube 401 is detachably connected to the water inlet 2 , and the connecting tube 402 is fixedly connected to the outer wall of the filter tube 401 , and both connecting tubes 402 are communicated with the interior of the filter tube 401 .

[0033] In this embodiment, water flows into the filter tube 401, passes through the first filter cartridge 4010 and the first connecting tube 402, and the first filter cartridge 4010 performs a first filtration on the sediment in the water. After the first filtration, the water passes through the second filter cartridge 4010 and the second connecting tube 402, and the second filter cartridge 4010 performs a second filtration on the sediment in the water.

[0034] Please refer to Figure 3 The disassembly and assembly components include a connecting plate 404, a stud 405, a fixing rod 406, two covers 403, a T-slot 407, a T-block 408, a sealing ring 409, a threaded head 4011 and an internal thread 4012;

[0035] The sealing cover 403 is detachably connected to the connecting tube 402, and the two ends of the connecting plate 404 are fixedly connected to the two sealing covers 403 respectively. The fixing rod 406 is fixedly connected to the outer wall of the filter tube 401, and the fixing rod 406 has a hollow structure. The stud 405 is arranged at the center of the connecting plate 404, and the stud 405 is threadedly connected to the fixing rod 406. The T-slot 407 is opened on the inner wall of the connecting tube 402, and the T-shaped block 408 is fixedly connected to the edge of the sealing cover 403. The sealing ring 409 is arranged on the surface of the sealing cover 403, the threaded head 4011 is fixedly installed at the center of the sealing cover 403, and the internal thread 4012 is arranged on the inner wall of the filter cartridge 4010.

[0036] In this embodiment, the filter cartridge 4010 is aligned with the cover 403, and the threaded head 4011 is threadedly connected with the internal thread 4012, so that the threaded head 4011 and the internal thread 4012 in the threaded connection state connect the filter cartridge 4010 with the cover 403 for docking installation. As described above, the two filter cartridges 4010 are docked with the two cover 403 respectively. At this time, the two filter cartridges 4010 are respectively inserted into the two connecting pipes 402, so that the T-shaped block 408 at the edge of the cover 403 is inserted into the T-shaped groove 407. Then, the T-shaped groove 407 and the T-shaped block 408 in the engaged state connect the connecting pipe 402 and the cover 403. Perform pre-connection. As mentioned above, pre-connect the two covers 403 with the two connecting pipes 402 respectively. At this time, rotate the stud 405 to thread the stud 405 with the fixing rod 406. The threaded stud 405 and the fixing rod 406 dock the two connecting pipes 402 in the pre-connected state with the two covers 403. During this installation and fixation, the outer wall of the cover 403 and the inner wall of the connecting pipe 402 squeeze the sealing ring 409, so that the sealing ring 409 is deformed by force and fits tightly at the docking point between the cover 403 and the connecting pipe 402, effectively improving the sealing performance of the docking installation between the cover 403 and the connecting pipe 402.

[0037] Please refer to Figure 4The filter cartridge 4010 and the sealing cover 403 are detachably connected, and the threaded head 4011 and the internal thread 4012 in the threaded connection state are used to dock and install the filter cartridge 4010 and the sealing cover 403.

[0038] In this embodiment, the thread head 4011 is threadedly connected to the internal thread 4012 , so that the thread head 4011 and the internal thread 4012 in the threaded connection state connect the filter cartridge 4010 and the cover 403 for docking installation.

[0039] Please refer to Figure 3 The T-slot 407 is used for inserting the T-block 408 into it, and the T-slot 407 and the T-block 408 in the engaged state are used to pre-connect the connecting pipe 402 and the cover 403, and the stud 405 and the fixing rod 406 in the threaded connection state are used to dock and install the pre-connected connecting pipe 402 and the cover 403.

[0040] In this embodiment, the T-shaped block 408 at the edge of the cover 403 is inserted into the T-slot 407 , and the T-slot 407 and the T-shaped block 408 in the engaged state pre-connect the connecting pipe 402 and the cover 403 .

[0041] Working principle: First, align the filter cartridge 4010 with the cover 403, and thread the thread head 4011 with the internal thread 4012 to connect the filter cartridge 4010 and the cover 403. As mentioned above, connect the two filter cartridges 4010 with the two covers 403 respectively. Then, insert the two filter cartridges 4010 into the two connecting pipes 402 respectively, and insert the T-shaped block 408 at the edge of the cover 403 into the T-shaped groove 408. 7, the T-shaped groove 407 and the T-shaped block 408 in the engaged state pre-connect the connecting pipe 402 and the cover 403. As described above, the two covers 403 are pre-connected with the two connecting pipes 402 respectively. At this time, the stud 405 is rotated to make the stud 405 and the fixing rod 406 threadedly connected. The stud 405 and the fixing rod 406 in the threaded connection state dock the two connecting pipes 402 and the two covers 403 in the pre-connected state, and in this installation and fixation, the outer wall of the cover 403 and the connecting pipe 402 are fixed. The inner wall squeezes the sealing ring 409, causing the sealing ring 409 to deform under stress and fit tightly at the joint between the cover 403 and the connecting pipe 402, effectively improving the sealing performance of the joint installation between the cover 403 and the connecting pipe 402. At this time, the two filter cartridges 4010 are completely installed inside the two connecting pipes 402 (it should be noted that the filter pore density of the two filter cartridges 4010 is different, and the filter pore density of the filter cartridge 4010 near the input end of the filter pipe 401 is greater than that of the other filter cartridge 4010 near the output end of the filter pipe 401). The water body first passes through the first filter cartridge 4010 and the first connecting pipe 402, so that the first filter cartridge 4010 performs a first filtration on the sediment in the water body. After the first filtration, the water body passes through the second filter cartridge 4010 and the second connecting pipe 402, so that the second filter cartridge 4010 performs a second filtration on the sediment in the water body. Thus, the sediment in the water body is filtered twice through the above structure.
