The third annular notch 57 and the fourth annular boss 58 are arranged on the surface of the plugging support column 21. The second vertical boss 59 is arranged between the third annular notch 57 and the filter end cover 2. After such arrangement, the third annular notch 57 can be adapted to an external clamp. The fourth annular boss 58 can not only increase the friction inside the pipeline, but also play a role in limiting the clamp after the clamp is installed. Among them, the second vertical boss 59 limits the longest insertion distance of the inserted pipeline, and also facilitates users to increase the friction force when disassembling and assembling the filter end cover 2, facilitating disassembly and replacement.

[0034] Working principle and usage method of the present utility model:

[0035] Install the pipeline joint assembly 4 at one end of the filter housing 1, connect the filter end cap 2 of any embodiment to the other end of the filter housing 1, then connect the external pipeline to the inside of the first threaded inner groove 411, and connect the external pipeline to the plugging support column 21 on the filter end cap 2. The anti-slip structure 5 can facilitate the plugging of the external pipeline and the installation of the clamp. Then, after the filter is filled with water, the water enters from the inside of the pipeline joint assembly 4, passes through the filter element 3, and flows out from the filter end cap 2. A filter element cotton 7 for filtering eggs can be provided outside or inside the filter element 3. Activated carbon or calcium sulfite can also be provided inside the filter element 3. When the filtered water passes through the inside of the filter end cap 2, the circular plate chute 621 on the diversion circular plate 62 will slide on the surface of the circular plate support column 612 until one end of the diversion circular plate 62 is stuck at the end of the second limit boss 613. At this time, the water flow is normal. However, whenever the water in the water inlet pipe reverses, the diversion circular plate 62 will slide towards the inside of the anti-backflow column 61 until the diversion circular plate 62 blocks the area in the middle of the anti-backflow column 61, thereby realizing the situation of water backflow.
