[0002] In the field of filter technology, the filter element is the core component of the filtration device, and its structural design has a crucial impact on filtration effect, ease of installation, and production cost.

[0003] In traditional filter cartridge designs, the adhesive component used to secure the telescopic clips on both sides is typically a separate spin-melted cap. This design results in a large number of parts and a complex structure, increasing mold development costs (requiring separate molds for multiple different parts) and making assembly processes cumbersome, thus reducing production efficiency. Furthermore, the complex inter-part relationships can lead to loosening and jamming during long-term use, affecting the normal operation and filtration efficiency of the filter cartridge. Therefore, there is an urgent need to design a spring-loaded telescopic clip filter cartridge mechanism to solve these problems. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown in the figure, the spring block telescopic locking filter element mechanism provided by this utility model includes a cylindrical shell 1. One end of the cylindrical shell 1 is provided with a mounting base plate 17. The upper surface of the mounting base plate 17 is provided with a spring block mechanism 4. The spring block mechanism 4 includes two sliding blocks 41. The sliding blocks 41 are slidably disposed on the mounting base plate 17. A decorative cover 2 is provided above the spring block mechanism 4. A rotating seat 21 is provided on the decorative cover 2. A split and assembled prying buckle plate 3 is provided on the upper surface of the decorative cover 2. A rotating block 31 is provided on the lower surface of the prying buckle plate 3. A shaft 33 is provided on both sides of the rotating block 31. The shaft 33 is inserted into the rotating seat 21. A spun-melted cap 5 is inserted into the other end of the cylindrical shell 1.

[0026] In this embodiment, the outer shell 1 is made of food-grade PP material by injection molding and is cylindrical in shape. One end of the outer shell 1 is provided with a mounting base plate 17. The upper surface of the mounting base plate 17 is provided with a spring block mechanism 4. The spring block mechanism 4 includes two sliding blocks 41. The end of the sliding block 41 near the opening 15 is provided with an arc transition, which can reduce wear during the insertion and removal process. The sliding block 41 is slidably mounted on the mounting base plate 17. A decorative cover 2 is provided above the spring block mechanism 4. A rotating seat 21 is provided on the decorative cover 2. The rotating seat 21 and the decorative cover 2 are integrally injection molded. The rotating seat 21 is used to fix the prying buckle plate 3. The upper surface of the decorative cover 2 is provided with a prying buckle plate 3 that is separately assembled. The lower surface of the prying buckle plate 3 is provided with a rotating block 31. A shaft 33 is provided on both sides of the rotating block 31. The shaft 33 is inserted into the rotating seat 21, so that the rotating block 31 and the shaft 33 rotate with the rotating block 31 and the shaft 33 as the center.

[0027] In this embodiment, a rotating shaft 13 is provided at the center of the upper surface of the mounting base plate 17 for fixing the torsion member 42. Limiting grooves 16 are provided on both sides of the rotating shaft 13 on the mounting base plate 17 to limit the sliding of the sliding block 41 and provide a guiding effect for the sliding block 41. Limiting blocks 14 are provided on the upper surface of the mounting base plate 17 to limit the range of motion of the sliding block 41 and prevent the sliding block 41 from falling off due to excessive movement. The limiting blocks 14 are located on both sides of one of the limiting grooves 16. Two openings 15 are provided on the outer shell of the cylinder 1. The sliding block 41 is inserted into the opening 15 and extends to the outside of the outer shell of the cylinder 1 through the opening 15.

[0028] In this embodiment, a torsion member 42 is provided between the two sliding blocks 41. A torsion spring made of spring steel is provided on the torsion member 42. After installation, it can generate a continuous elastic force on the sliding blocks 41, ensuring that the sliding blocks 41 can remain in the initial position when there is no external force. The torsion member 42 is inserted into the rotating shaft 13. A limit plate 43 is provided at the tail of each of the two sliding blocks 41. The limit plate 43 is snapped onto the torsion member 42, so that the sliding blocks 41 are connected to the torsion member 42 through the limit plate 43. When the torsion member 42 rotates, it can drive the two sliding blocks 41 to slide inward or outward at the same time.

[0029] Specifically, the sliding block 41 is hollow in the middle, and a limiting slider 44 is provided on the inner wall of the hollow side of the sliding block 41. The limiting slider 44 is slidably inserted into the limiting groove 16, and the limiting block 14 is located in the hollow part of the sliding block 41, providing installation space for the limiting block 14.

[0030] In this embodiment, a paddle 34 is provided on the lower surface of the rotating block 31. The paddle 34 and the rotating block 31 are integrally formed. One side surface of the paddle 34 is in close contact with one side surface of the limiting slider 44. When the rotating block 31 drives the paddle 34 to rotate, the paddle 34 will squeeze the limiting slider 44 and at the same time make the sliding block 41 move inward, so that the sliding block 41 completely enters the outer shell 1 of the cylinder, thereby contacting the limiting and fixing of the outer shell 1 of the cylinder by the sliding block 41. A buckle 32 is provided on the prying buckle plate 3 to facilitate the prying operation by inserting a finger.

[0031] In this embodiment, a spin-welded cap 5 is inserted into the other end of the outer shell 1. A slot 11 is provided at one end of the outer shell 1. A sealing ring 12 is provided on the bottom wall of the slot 11 to ensure sealing performance and prevent leakage. The edge interface of the spin-welded cap 5 is inserted into the slot 11. An inlet 51 and an outlet 54 are respectively provided on the spin-welded cap 5. A water source pipe is inserted into the inlet 51, and a drain pipe is inserted into the outlet 54. A rubber ring 52 is provided on the inner wall of the inlet 51 to ensure the airtightness of the external water pipe and prevent leakage. A one-way valve 53 is provided in the inlet 51 to prevent the filtered water from flowing back.

[0032] In this embodiment, a filter element 6 is provided inside the outer shell 1 of the cylinder. The filter element 6 adopts a composite filter element structure. One end of the filter element 6 is provided with a water inlet port 61, which is connected to the water inlet 51. Water enters the filter element 6 through the water inlet 51 and the water inlet port 61 in sequence.

[0033] In this embodiment, the decorative cover 2 has a number of countersunk holes 22, and the number of countersunk holes 22 is 4. They are evenly distributed on the edge of the decorative cover 2 with equal spacing. When used with screws, the screw head can be completely recessed into the holes, so that the upper surface of the decorative cover 2 remains flat. The decorative cover 2 is fixed to the mounting base plate 17 by screws.

[0034] Working steps: 1. Place the filter element 6 inside the outer shell 1 of the cylinder, insert the edge interface of the spin-welded cap 5 into the slot 11 at one end of the outer shell 1 of the cylinder, and use the sealing ring 12 to achieve a seal.

[0035] 2. Install the spring block mechanism 4 on the mounting base plate 17, connect the two sliding blocks 41 through the torsion member 42, insert the torsion member 42 into the rotating shaft 13 at the center of the mounting base plate 17, and the limiting plate 43 at the tail of the two sliding blocks 41 is engaged with the torsion member 42 to ensure linkage. The limiting slider 44 is slidably inserted into the limiting groove 16 on the mounting base plate 17.

[0036] 3. Place the decorative cover 2 above the spring block mechanism 4, and fix the decorative cover 2 to the mounting base plate 17 with screws through the countersunk hole 22 on the decorative cover 2. Fix the rotating block 31 on the prying buckle plate 3 to the rotating seat 21.

[0037] 4. When it is necessary to operate the spring block mechanism, the buckle 32 on the buckle plate 3 is turned to move the buckle plate 3, so that the rotating block 31 rotates around the shaft 33. The paddle 34 on the lower surface of the rotating block 31 will push the limiting slider 44 on the sliding block 41, so that the sliding block 41 slides in the limiting groove 16, realizing the extension and retraction of the spring block, thereby completing the corresponding locking or unlocking operation.

[0038] 5. Water enters through the inlet 51 on the spin-welded cap 5, and flows into the inlet 61 of the filter element 6 under the control of the rubber ring 52 and the one-way valve 53. After being filtered inside the filter element 6, the water flows out from the outlet 54, completing the filtration process.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
