[0003] Chinese patent CN214437019U discloses a precision filter with an easy-to-replace filter element, including a filter body, a filter element, a cover plate, and a clamping mechanism and a fixing mechanism disposed within the filter body. The filter element is disposed within the filter body by the clamping mechanism, and the cover plate is disposed on the filter body by the fixing mechanism. A filter groove is formed on the lower end face of the filter body, and symmetrical clamping grooves are formed on the side wall of the filter groove. The clamping mechanism includes a clamping component, a driving component, and a transmission component. The driving component passes through the filter body. The driving component includes a rotating rod, a limiting block, and a threaded block. The rotating rod passes laterally through the filter body. Two limiting blocks are respectively disposed on the rotating rod near its two ends. Two threaded blocks are respectively sleeved on the two ends of the rotating rod. The clamping component includes two clamping plates. This utility model facilitates the fixing of the filter element, so as to facilitate the quick replacement of the filter element and avoid the cumbersome and time-consuming disassembly and replacement in the future.

[0004] However, the aforementioned patent requires that when the soft filter element needs to be disassembled and replaced, the pipeline must be manually shut off first to stop the internal liquid flow before the filter element can be disassembled, which is not convenient for quick disassembly and assembly.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a filter element assembly, comprising: a fixed hose 1, a water pipe 3, and an outer pipe 4. One end of the fixed hose 1 is fixedly connected to a threaded pipe 2, and the other end of the threaded pipe 2 is fixedly connected to one end of the water pipe 3 as a single unit. The fixed hose 1 is flexible, thus facilitating direction adjustment. The surface of the threaded pipe 2 is threadedly connected to one end of the inner wall of the outer pipe 4. When the outer pipe 4 rotates, it can rotate and move up and down along the threaded pipe 2. A rotating groove 5 is provided on the inner wall of the outer pipe 4. Several fixing plates 6 are provided, and one end of the fixing plate 6 is inserted into the rotating groove 5 and rotatably connected to the inner wall of the outer pipe 4. The groove 5 facilitates the positioning and guidance of the fixed plate 6. The other end of the fixed plate 6 is fixedly connected to the limiting member 14. The surface of the limiting member 14 contacts the inner arc surface of the buffer ring 7, and a rubber ring is installed at the connection between the two to improve the sealing performance. The inner wall of the water pipe 3 is fixedly connected to the buffer ring 7. A sealing groove 8 is opened on the surface of the buffer ring 7. The diameter of the sealing groove 8 is equal to the diameter of the bottom end of the cone plate 9. Several sliding grooves 15 are opened at the end of the water pipe 3 near the threaded pipe 2. The surface of the fixed plate 6 contacts the inner wall of the sliding groove 15. The fixed plate 6 can be guided and positioned through the sliding groove 15. The fixed plate 6 and the sliding groove 15 are slidably connected.

[0019] The threaded pipe 2 is brought into contact with the water pipe 3, and the outer pipe 4 slides along the fixed hose 1. At the same time, the fixing plate 6 is aligned with the slide groove 15. When the thread inside the outer pipe 4 comes into contact with the threaded pipe 2, the outer pipe 4 is rotated. At this time, the fixing plate 6 will rotate in the rotating groove 5. The outer pipe 4 moves along the threaded pipe 2 until the fixing plate 6 comes into contact with the end of the slide groove 15. At this time, the surface of the threaded pipe 2 is threadedly connected to the inner wall of the outer pipe 4. At the same time, the threaded pipe 2 is in close contact with the water pipe 3, and the contact surface between the water pipe 3 and the outer pipe 4 is sealed by the thread.

[0020] A magnet 13 is fixedly connected to the middle position of the bottom end of the cone plate 9. One end of several connecting rods 10 is fixedly connected to the cone plate 9. The connecting rods 10 move with the cone plate 9. The other end of the connecting rods 10 passes through the sealing groove 8 on the surface of the buffer ring 7 and is fixedly connected to a limiting plate 11. The limiting plate 11 can prevent the connecting rods 10 from coming out of the sealing groove 8. The connecting rods 10 are slidably connected to the buffer ring 7. The fixing plate 16 is attracted by the magnet 13. When the fixing plate 16 moves, the cone plate 9 can be moved together by the magnet 13. The fixed plate 16 is fixedly connected to several connecting plates 17, and the other end of the connecting plates 17 is fixedly connected to the limiting member 14. The fixed plate 16 can be fixed through the connecting plates 17, and the fixed plate 16 can also be fixed through the connecting rod 10. One end of the filter element 12 is in contact with the fixed plate 16, and the side of the other end of the filter element 12 is in close contact with the limiting member 14. Water can be filtered through the filter element 12. The several connecting plates 17 are embedded in the surface of the filter element 12, so the filter element 12 is not easily deformed by pressure and falls out.

[0021] When the outer tube 4 moves the fixed plate 6, the fixed plate 6 can move the limiting member 14. At this time, the filter element 12 moves accordingly. At this time, the fixed plate 16 will contact the cone plate 9. When the filter element 12 continues to move, the fixed plate 16 will force the cone plate 9 to move. At this time, the connecting rod 10 slides accordingly. The water in the water pipe 3 contacts the filter element 12 and enters the threaded pipe 2 after filtration.

[0022] A precision filter, including a filter element assembly.

[0023] In actual use, the liquid enters through the water pipe 3, then passes through the filter element 12 and is discharged through the fixed hose 1. When the filter element 12 needs to be replaced after long-term use, the outer pipe 4 is rotated. At this time, the fixed plate 6 moves along the slide groove 15 towards the threaded pipe 2. During this process, the fixed plate 16 drives the cone plate 9 to move towards the sealing groove 8 through the magnet 13. When the outer pipe 4 is not connected to the threaded pipe 2, the cone plate 9 contacts the sealing groove 8 and maintains a tight contact with the sealing groove 8 under the water pressure inside the water pipe 3, thereby preventing leakage. Then, the outer pipe 4 is slid to make the fixed plate 16 disengage from the magnet 13. Then, the angle of the fixed hose 1 can be turned and the filter element 12 can be taken out. The filter element 12 can be a soft water resin filter element. The entire device can automatically shut off the flow of internal liquid during the removal of the filter element 12 and can automatically open during installation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
