It contains an RO membrane for filtering raw water, removing impurities, salts, and other harmful substances to obtain purified water. A raw water sealing ring 2 is fixedly connected to the outside of the RO membrane filter element 1. A water guide pipe 3 is fixedly connected inside the RO membrane filter element 1 to provide a flow channel for the water source. One end of the water guide pipe 3 is fixedly connected to a telescopic folding pipe 4, which can extend or retract during installation and disassembly, facilitating docking and separation with other components. A connecting block 5 is fixedly connected to the upper outer side of the telescopic folding pipe 4. A connecting mechanism 6 is provided at the top of the telescopic folding pipe 4 for installation and disassembly. A limiting mechanism 7 is provided at one end of the RO membrane filter element 1 to limit the telescopic folding pipe 4. Four sets of connecting blocks 5 are symmetrically arranged on the upper outer side of the telescopic folding pipe 4.

[0021] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The connecting mechanism 6 includes a short tube 601, an internally threaded locking member 602, and a rotating handle 603. The short tube 601 is fixedly connected to the top of the telescopic folding tube 4. The internally threaded locking member 602 is threadedly connected to the outside of the short tube 601, and the rotating handle 603 is fixedly connected to the outside of the internally threaded locking member 602. It also includes an external connecting tube 604, a magnetic ring 605, and a sealing washer 606. The external connecting tube 604 is threadedly connected to the inside of the internally threaded locking member 602. The magnetic ring 605 is fixedly connected to the top of the short tube 601, and the sealing washer 606 is sleeved on the outside of the magnetic ring 605. Finally, it includes an annular groove 607 and a magnetic ring 608. The annular groove 607 is formed at the bottom of the external connecting tube 604, and the magnetic ring 608 is fixedly connected to... The sealing gasket 606 is fitted inside the annular groove 607. During installation, first connect the external connecting pipe 604 to the external pipe to be connected, such as a filter bottle. Then align the short pipe 601 with the external connecting pipe 604, so that the magnetic ring 605 and the sealing gasket 606 are located in the annular groove 607 of the external connecting pipe 604. The magnetic ring 605 and the magnetic ring 608 attract each other to form a preliminary position. Then hold and twist the handle 603 to place the internal threaded locking member 602 between the short pipe 601 and the external connecting pipe 604, so that the two form a fixed rotation state. In this way, with the sealing gasket 606, a double and effective seal is formed to prevent liquid leakage.

[0022] Reference Figure 1 and Figure 6The limiting mechanism 7 includes a cover 701, a support sleeve 702, and a top plate 703. The cover 701 is fixedly connected to one end of the RO membrane filter element 1, the support sleeve 702 is fixedly connected to the top end of the cover 701, and the top plate 703 is fixedly connected to the outer end of the support sleeve 702. Both the cover 701 and the top plate 703 are fixedly connected to the water guide pipe 3. A spring 704 and a limiting rod 705 are also included. The spring 704 is fixedly connected inside the support sleeve 702, and the limiting rod 705 is movably inserted into the inner side of the support sleeve 702. The limiting rod 705 is further... One end is fixedly connected to the connecting block 5. There are four sets of support sleeves 702, springs 704 and limiting rods 705. The four sets of support sleeves 702 are symmetrically arranged on the top of the cover 701. The other end of the spring 704 is fixedly connected to the limiting rod 705. The limiting rod 705 is lifted by the spring 704. Through its connection with the connecting block 5, the telescopic folding tube 4 can be limited to prevent it from shifting due to external force during operation. It also ensures that the filter element maintains a stable position during operation, thereby improving the filtration effect and reliability.

[0023] The working principle of this utility model is as follows: During installation, first connect the external connecting pipe 604 to the external pipe to be connected, such as a filter bottle, and then align the short pipe 601 with the external connecting pipe 604, so that the magnetic ring 605 and the sealing gasket 606 are located in the annular groove 607 of the external connecting pipe 604. The magnetic ring 605 and the magnetic ring 608 attract each other to form a preliminary positioning. Then, hold and twist the handle 603 to place the internal threaded locking member 602 between the short pipe 601 and the external connecting pipe 604, so that the two are in a fixed rotating state. In this way, with the sealing gasket 606, a double and effective seal is formed to prevent liquid leakage and ensure the sealing and stability of the connection. The connection method of the sealing gasket 606 and the magnetic ring 605 makes it easy to replace. During disassembly, rotate the handle 603 in the opposite direction. The internal threaded locking member 602 rotates in the opposite direction, releasing the fixed state of the short tube 601 and the external connecting tube 604. Then, pressing the connecting block 5 causes the limiting rod 705 to retract into the support sleeve 702, and at the same time, the telescopic folding tube 4 is retracted, thereby removing the magnetic ring 605 and the sealing gasket 606 of the short tube 601 from the ring groove 607, thus completing the entire loading and unloading process. This method can achieve flexible and quick disassembly and installation without the need for tools, improving overall efficiency. After installation, the limiting rod 705 is lifted by the spring 704, and its connection with the connecting block 5 can limit the telescopic folding tube 4, preventing it from shifting due to external force during operation. This also ensures that the filter element maintains a stable position during operation, improving filtration effect and reliability.
