[0030] Please refer to Figure 8 A filter core comprises a filter core shell 4 with a water inlet and a water outlet, and at least one filter material one-way release structure is arranged in the filter core shell 4 and can be fixed in the filter core shell 4 through the positioning part 102. Water enters the filter core shell 4 through the water inlet of the filter core shell 4, enters the pipe body 1 from the water inlet of the filter material one-way release structure, is reacted, is discharged from the water outlet of the pipe body 1, and is finally discharged from the water outlet of the filter core shell 4.

[0031] Working principle: after the water flow enters the water inlet of the filter core shell 4, it first passes through the filter cartridge 303 of the water inlet part 3, enters the cavity 101 inside the pipe body 1, and the cavity 101 is filled with filter material for water treatment. When the water flow passes through, the design of the baffle 104 and the rotating plate 105 ensures that the water can only flow forward, avoiding the problem of reverse flow of the water flow. The rotating plate 105 is adjusted by the combination of the first extension rod 107 and the first spring 108, ensuring that the water flow can smoothly discharge after passing through the filter material, while the reverse pressure cannot open the rotating plate 105, preventing backflow. This one-way release design not only improves the safety of the filter, but also effectively prolongs the service life of the filter material, ensuring that the water flow always flows in one direction along the set path, thereby ensuring the filtering effect. The side of the pipe body 1 is provided with a clamping groove 103, which forms a clamping structure with the clamping block 202 on the connecting part 2. Four clamping blocks 202 are distributed circumferentially, ensuring the stability and shock resistance of the structure when bearing the water flow pressure, avoiding loosening or leakage caused by vibration or water pressure fluctuations. In addition, the connecting part 2 is also equipped with an external thread joint 201 connected to the second extension rod 110 through the nut 113, realizing the tight connection between components, not only enhancing the overall structural strength, but also ensuring the convenience of installation and disassembly, facilitating users to replace the filter core and maintain the system. The design of the threaded connection structure improves the sealing performance of the system, ensuring that the water flow will not leak under high pressure conditions, enhancing the durability and long-term stability of the structure. After the water flow passes through the water inlet part 3, it enters the filter cartridge 303 inside the annular block 302. The filter cartridge 303 optimizes the distribution of the water flow, making it pass through the filter material uniformly, reducing dead angles and unfiltered areas. The entire filtration process is carried out from the inside out. After the water flow passes through the filter material, impurities are blocked on the surface of the filter material, and the water purified by the filter material is discharged from the water outlet. The one-way port 230 is located inside the cavity 101 and in front of the rotating plate 105. This design helps to maximize the utilization efficiency of the filter material and avoid damage or contamination of the filter material during the filtration process. The cooperation of the fixed sheet 109 and the second extension rod 110 makes the nut 113 have certain adjustability. During use, the nut 113 can be tightly adjusted by rotating, ensuring the stable connection of the components in a high-pressure environment, avoiding leakage or loosening. This not only improves the durability of the overall structure, but also provides great convenience for daily maintenance. At the same time, the elastic design of the second spring 112 enhances the buffering performance of the system, allowing it to maintain structural stability under frequent use, prolonging the overall service life.
