[0038] Specifically, such as Figure 1 and Figure 4 As shown, anti-slip protrusions 14 are fixedly installed on the outer wall of the sealing ring plate 12. This improves the stability of the hand gripping the sealing ring plate 12.

[0039] In summary, the structure of the first fixed tube 10, sealing ring plate 12, anti-slip protrusion 14, filter cartridge 19, limiting groove 20, first guide tube 21 and second guide tube 22 achieves the purpose of conveying liquid, increases the friction between the hand and the device, enhances the safety of the device, prevents the device from slipping out of the hand and falling, and optimizes the user experience of the device.

[0040] Working principle: Three sets of first fixing sleeves 23 are fixed to the bottom inner side of the first fixing tube 10, and three sets of second hexagonal limiting grooves 24 are opened inside the sleeves. Three sets of second hexagonal limiting grooves 29 are opened at the bottom of the first fixing tube 10. Three sets of first hexagonal locking blocks 26 are fixed to the top of the quick-release circular plate 25, and second hexagonal locking blocks 27 are fixed to the outer wall of the first hexagonal locking blocks 26. During installation, the first hexagonal locking blocks 26 are inserted into the second hexagonal limiting grooves 29, and the second hexagonal locking blocks 27 are inserted into the first hexagonal limiting grooves 24, thereby locking the quick-release circular plate 25 into the bottom of the first fixing tube 10, realizing the quick connection and disassembly of the quick-release circular plate 25 and the first fixing tube 10, which facilitates the subsequent operation of the filter element. The filter element cylinder 19 is fixed inside the first fixing tube 10, and a limiting hole 28 is opened at the bottom and communicates with the filter element cylinder 19. After the quick-release circular plate 25 is installed, the filter element can be inserted into the filter element cylinder 19 through the limiting hole 28. The quick-release circular plate 25 seals the limiting hole 28 to prevent liquid leakage and facilitates subsequent removal and replacement of the filter element. The outer wall of the first fixing tube 10 has a first threaded groove 11, and the sealing ring plate 12 has a second threaded groove 15 inside. Rotating the sealing ring plate 12 causes the second threaded groove 15 to be spirally installed on the outer wall of the first threaded groove 11, thus connecting the sealing ring plate 12 with the first fixing tube 10. The first infusion tube 13 and the second infusion tube 16 are fixed inside the sealing ring plate 12, with one end of the two fixedly connected. A sealing rubber ring 30 is fitted on the outer wall of the second infusion tube 16, and a first limiting rubber ring 17 is fixed on the inner wall. A second limiting rubber ring 18 is fixed on the inner wall of the first fixing tube 10. When the sealing ring plate 12 is installed on the outer wall of the first fixed tube 10, the outer wall of the sealing ring 30 is tightly attached to the bottom of the second limiting ring 18, sealing the first fixed tube 10 and the sealing ring plate 12 to prevent liquid leakage at the connection. The liquid is transported through the first infusion pipe 13 and the second infusion pipe 16. The liquid enters from the first infusion pipe 13 and flows into the filter through the second infusion pipe 16. Two sets of holes are opened on the outer wall of the first fixed tube 10 to fix the first guide pipe 21 and the second guide pipe 22 respectively. One end of the first guide pipe 21 is fixed inside the filter element cylinder 19. Liquid can also be transported through the first feed pipe 21 and the second feed pipe 22, allowing the liquid to enter the filter cartridge 19 for filtration. A limiting groove 20 is provided on the inner wall of the filter cartridge 19. After the filter element is placed inside the filter cartridge 19, the outer wall of the filter element is in close contact with the inner wall of the limiting groove 20. The limiting groove 20 plays an auxiliary role in fixing the filter element, ensuring that the filter element is stable in position during the filtration process and ensuring the filtration effect. Anti-slip protrusions 14 are fixed on the outer wall of the sealing ring plate 12. When installing or removing the sealing ring plate 12, the anti-slip protrusions 14 can increase the friction between the hand and the sealing ring plate 12, improve the stability of the grip, and facilitate the operator to perform related operations.
