[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a press-fit filter element structure, comprising: a filter element body 6; an RO membrane assembly 5, which is placed inside the filter element body 6, and is the same as a conventional RO membrane, consisting of a membrane sheet, a central tube, a filter screen, a filter cloth, adhesive, etc., used to intercept microorganisms and bacteria in the water; and a press-fit assembly, which is placed at the end of the filter element body 6, and is detachably installed on the filter element cover 7 at the bottom of the filter element body 6. Two snap fasteners 8 are slidably installed on the outer side of the filter element cover 7 for connection and fixation, and an elastic element is provided between the two snap fasteners 8 for driving the snap fasteners 8 to move to both ends.

[0022] It should be noted that in this embodiment, the filter element cover 7 and the barrel body are fixed together by spin welding to form a complete filter element. A spring 10 is installed between the clips 8. By pressing the clips 8 simultaneously, the clips 8 move inward. When there is no external pressure on the clips 8, the spring force of the spring 10 between the clips 8 causes the clips 8 to return to their original position and be in the extended state, thus fixing them to the whole machine. When disassembling, both clips 8 are driven towards the middle at the same time, so that the clips 8 are separated from the connection part of the whole machine, thereby removing the filter element structure.

[0023] In one embodiment, a connecting water pipe 1 is fixedly connected to the end of the filter cartridge body 6. A sealing ring 3 and a gasket 4 are fitted on the outside of the connecting water pipe 1. Both the sealing ring 3 and the gasket 4 are interference-fitted with the filter cartridge body 6. The sealing ring 3 acts as a sealing ring, with the outer ring fixed to the filter cartridge body and the inner ring interference-fitted with the connecting water pipe 1. This double sealing ring structure reduces the risk of product leakage. The gasket 4 is used to elevate the sealing ring 3, making the contact position between the sealing ring 3 and the connecting water pipe 1 deeper, preventing the risk of the connecting water pipe 1 coming off due to the filter cartridge retraction during the pressurization process. A push rod 2 is movably installed inside the connecting water pipe 1. One-way valves are installed at both ends of the connecting water pipe 1. One of the two one-way valves is connected to the water circuit board, and the other is connected to the filter cartridge. The two ends of the push rod 2 are respectively in contact with the two one-way valve stems, so that when water passes through, the two one-way valves open simultaneously under the linkage of the push rod 2.

[0024] It should be noted that in this embodiment, one end of the push rod 2 contacts the one-way valve stem on the water circuit board, and the other end contacts the one-way valve stem on the filter element. Through the cooperation between the filter element and the water circuit board and the elastic force of the spring 10 inside the one-way valve, the one-way valves on the water circuit board and the filter element are simultaneously pushed by the push rod 2, opening the one-way valves on the filter element and the water circuit board at the same time. When there is no pressure from the push rod 2, the one-way valve inside the filter element is in a sealed state, and water cannot flow out. When the filter element is installed on the water circuit board, due to the pressure of the push rod 2, the one-way valve stems on the filter element and the water circuit board contract, and the internal sealing ring 3 is in an open state, forming a complete water circuit. The gasket 4 inside the filter element raises the position of the sealing ring 3, allowing the push rod 2 to be inserted deeper into the filter element, making the seal more secure.

[0025] In one embodiment, a limiting groove 11 for sliding the buckle 8 is provided in the middle of the filter cover 7. A stop block 12 is fixedly connected inside the limiting groove 11. A decorative cover 9 is fixedly connected to the end of the filter cover 7. A limiting hole 13 is opened in the middle of the decorative cover 9. A driving block 14 is slidably connected inside the limiting hole 13. The driving block 14 is fixedly connected to the end of the buckle 8. The elastic element is a spring 10. A round rod that cooperates with the spring 10 is fixedly connected to the end of the buckle 8. The end of the spring 10 is sleeved on the outside of the round rod.

[0026] It should be noted that in this embodiment, the filter element is welded to the filter element body assembly by spin welding. The limiting groove 11 is used to install the buckle 8, so that the buckle 8 cannot wobble left or right after installation. The top is fixed to the pressure plate 9 by ultrasonic welding, so that the buckle 8 cannot wobble up or down after installation. The stop block 12 inside the limiting groove 11 is used to limit the buckle retraction stroke so that the filter element can be taken out from the whole machine. By pressing the drive block 14 inside the limiting hole 13 at the same time, the drive block 14 drives the buckle 8 to move towards the center of the limiting hole 13 in the limiting groove 11. Due to the elastic force of the spring 10 inside, the buckle 8 automatically resets forward when there is no external pressure, so that the filter element is fixed on the whole machine, achieving the effect of filter element installation and removal.
