Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and specifically to a detachable filter element mechanism. Background Technology

[0002] Filter cartridges separate impurities from fluids through physical or chemical means, ensuring the cleanliness of the outflowing substances. In the field of water purification, filter cartridges play a crucial role. After a period of use, filter cartridges may fail due to the adhesion of dirt and grime, so water purifier filter cartridges need to be replaced regularly.

[0003] Some filter elements are integrated with their housings. When the filter element needs replacing, the entire housing must be discarded, wasting materials used in its manufacture and increasing the burden on consumers. Therefore, there is an urgent need to design a detachable filter element mechanism to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a detachable filter element mechanism to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A detachable filter element mechanism, wherein one end of the cylinder is rotatably fitted with a spin-welded cap, the other end of the cylinder is fitted with a pressure cap, the inside of the cylinder is fitted with a filter element body, two slots and two grooves are symmetrically opened on the periphery of opposite ends of the cylinder, two locking blocks are symmetrically installed on the periphery of the spin-welded cap, and two arc-shaped grooves are symmetrically opened on one end of the cylinder, the locking blocks are slidably fitted on one side of the arc-shaped grooves and correspond to the slots;

[0007] An opening is provided at the edge of the pressure cap, and a prying plate is rotatably fitted inside the opening. Two blocks corresponding to the two grooves are slidably fitted on the inner side of the pressure cap. A rhomboid block corresponding to the two blocks is rotatably fitted in the middle of the pressure cap, and a push plate corresponding to one of the blocks is installed at one end of the prying plate.

[0008] Furthermore, each of the two stops has a slot in the middle, and the push plate is located in one of the slots. A semi-circular slot is also provided in the middle of the adjacent ends of the two stops.

[0009] Furthermore, both ends of the rhomboid block are provided with arc-shaped surfaces corresponding to the semi-circular grooves, and sliding grooves are provided on both sides of the adjacent ends of the two blocks, with the arc-shaped surfaces slidingly fitted within the sliding grooves.

[0010] Furthermore, the inner sides of the two card slots and one side of the two card blocks are provided with inclined surfaces, the two adjacent inclined surfaces correspond to each other, and the two card slots are connected to the two arc-shaped grooves.

[0011] Furthermore, the center of the spin-melting cap is provided with an annular block corresponding to one end of the cylinder, and the filter element body corresponds to the spin-melting cap and the pressure cap.

[0012] Furthermore, the center of the swirl-melting cap is provided with multiple inlet and outlet ports corresponding to the filter element body, and threaded grooves are provided inside one end of the cylinder and on the lower periphery of the swirl-melting cap, with the two threaded grooves threaded together.

[0013] Furthermore, a hole is provided in the middle of the prying plate, and a spring is installed between the prying plate and the pressure cover.

[0014] In the above technical solution, the detachable filter element mechanism provided by this utility model has the following advantages:

[0015] 1. By rotating a lever within the opening, the lever drives a push plate to rotate synchronously. This push plate then pushes one of the stops, causing one end of a rhombus-shaped block to slide against one side of the stop. This drives the rhombus-shaped block to rotate, causing the other end to slide against one side of another stop and pull on that stop. This changes the distance between the two stops, disengaging them from the two grooves and allowing the cap to be disassembled. Furthermore, this technology is a breakthrough in similar structures in the industry, allowing direct replacement of any internal filter media, resulting in significant after-sales cost reduction.

[0016] 2. By setting two arc-shaped grooves, the two locking blocks slide and engage within the two arc-shaped grooves, thereby canceling the locking relationship between the two locking blocks and the two locking grooves. This also cancels the fixed relationship between the swivel cap and the cylinder body, allowing the swivel cap to be disassembled, thus enabling the filter element body to be removed and replaced without discarding the cylinder body, effectively improving the utilization rate of the cylinder body.

[0026] 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.

[0027] like Figure 1-7 As shown in the figure, a detachable filter element mechanism provided by this utility model includes a cylindrical body 1. One end of the cylindrical body 1 is rotatably fitted with a spin-melting cap 2, and the other end of the cylindrical body 1 is fitted with a pressure cap 3. The inside of the cylindrical body 1 is fitted with a filter element body 4. Two slots 5 and two grooves 6 are symmetrically opened on the periphery of opposite ends of the cylindrical body 1. Two locking blocks 7 are symmetrically installed on the periphery of the spin-melting cap 2. Two arc-shaped grooves 8 are symmetrically opened on one end of the cylindrical body 1. The locking blocks 7 are slidably fitted on one side of the arc-shaped grooves 8 and are corresponding to the slots 5. An opening 9 is opened at the edge of the pressure cap 3. A prying plate 10 is rotatably fitted in the opening 9. Two stops 11 corresponding to the two grooves 6 are slidably fitted on the inner side of the pressure cap 3. A rhomboid block 12 corresponding to the two stops 11 is rotatably fitted in the middle of the pressure cap 3. A push plate 13 is installed between the prying plate 10 and one of the stops 11.

[0028] In this embodiment, a cylinder 1 is included, one end of which is rotatably fitted with a spin-welding cap 2, the other end of which is fitted with a pressure cap 3, and a filter element body 4 is installed inside the cylinder 1.

[0029] Specifically, the middle part of the spin-melting cap 2 is equipped with an annular block 17 corresponding to one end of the cylinder 1, and the filter element body 4 corresponds to the spin-melting cap 2 and the pressure cap 3;

[0030] Specifically, the center of the swirl cap 2 is provided with multiple inlet and outlet ports 18 corresponding to the filter element body 4. Threaded grooves 19 are provided on the inside of one end of the cylinder 1 and on the lower periphery of the swirl cap 2. The two threaded grooves 19 are threaded together. Through the threaded engagement of the two threaded grooves 19, the cylinder 1 and the swirl cap 2 can be connected together to form a whole, so as to realize the installation or removal of the swirl cap 2.

[0031] In this embodiment, two slots 5 and two grooves 6 are symmetrically opened on the periphery of both ends of the cylinder 1, two locking blocks 7 are symmetrically installed on the periphery of the spin-melting cap 2, and two arc-shaped grooves 8 are symmetrically opened on one end of the cylinder 1. The locking blocks 7 are slidably engaged with one side of the arc-shaped grooves 8 and correspond to the slots 5.

[0032] Specifically, the inner sides of the two slots 5 and one side of the two blocks 7 are provided with inclined surfaces, with two adjacent inclined surfaces corresponding to each other, and the two slots 5 are connected to the two arc-shaped grooves 8. By having two adjacent inclined surfaces correspond to each other, the slots 5 limit the blocks 7, thereby reducing the occurrence of blocks 7 moving.

[0033] In this embodiment, an opening 9 is provided at the edge of the pressure cover 3, and a prying plate 10 is rotatably fitted inside the opening 9.

[0034] Specifically, a hole 20 is provided in the middle of the prying plate 10, and a spring is installed between the prying plate 10 and the pressure cover 3. The spring can drive the prying plate 10 to automatically return to its original position, reducing the situation where the two stops 11 are unstable due to the shaking of the prying plate 10.

[0035] In this embodiment, the inner side of the pressure cap 3 is slidably fitted with two stops 11 corresponding to the two grooves 6;

[0036] Specifically, each of the two stop blocks 11 has a slot 14 in the middle, and the push plate 13 is located in one of the slots 14. The middle of the adjacent ends of the two stop blocks 11 has a semi-circular groove 15. The slots 14 can reduce the obstruction to the push plate 13, so that the push plate 13 can rotate more smoothly.

[0037] In this embodiment, the middle part of the pressure cover 3 is rotatably fitted with a rhomboid block 12 corresponding to the two stops 11, and one end of the prying plate 10 is equipped with a push plate 13 corresponding to one of the stops 11.

[0038] Specifically, both ends of the rhombus block 12 are provided with arc-shaped surfaces corresponding to the semi-circular groove 15, and both sides of the adjacent ends of the two stops 11 are provided with sliding grooves 16. The arc-shaped surfaces slide in the sliding grooves 16. Through the two sliding grooves 16, the two ends of the rhombus block 12 slide in the two sliding grooves 16, thus preparing for the next step of driving the two stops 11 to engage and fix the two grooves 6.

[0039] Working steps: 1. When the filter element body 4 needs to be replaced, first rotate the swivel cap 2. At this time, the two locking blocks 7 slide and engage with one side of the two arc-shaped grooves 8, and the engagement with the two locking grooves 5 is canceled. At the same time, the two threaded grooves 19 engage with the reverse threads, thereby removing the swivel cap 2 from one end of the cylinder 1, thus disassembling the swivel cap 2. Then, put your hand into the hole 20 and pull the prying plate 10. At this time, the spring elastically extends and retracts. At the same time, prying the prying plate 10 drives the push plate 13 to rotate in one of its slots 14, so that the push plate 13 is aligned with one of its slots 14. The stop block 11 is pushed, so that one end of the rhombus block 12 slides in one of its grooves 16 and drives the rhombus block 12 to rotate, so that the other end of the rhombus block 12 slides in another groove 16 and pulls the other stop block 11. At this time, the two stop blocks 11 slide in the inner side of the cover 3, and at the same time change the distance between the two stop blocks 11. At this time, the two stop blocks 11 cancel the snap-fit ​​relationship with the two grooves 6, and the cover 3 cancels the fixed relationship with the cylinder 1, realizing the disassembly of the cover 3, so that the filter element body 4 can be taken out and replaced.

[0040] 2. When it is necessary to install the swivel-welded cover 2, rotate the swivel-welded cover 2 in the opposite direction. At this time, the two locking blocks 7 slide and engage with one side of the two arc-shaped grooves 8 and engage with the two locking grooves 5. At the same time, the two threaded grooves 19 engage with the threads, so that the swivel-welded cover 2 and the cylinder 1 are fixed together, thus realizing the installation of the swivel-welded cover 2.

[0041] 3. When installing the pressure cap 3, first insert your hand into the hole 20 and pull the lever 10. Then align the pressure cap 3 with the other end of the cylinder 1. At this time, release the pull on the lever 10. Simultaneously, the spring drives the lever 10 to elastically extend and retract and automatically return to its original position. This causes the lever 10 to drive the push plate 13 to rotate in the opposite direction and push one of its stops 11 in the opposite direction. As a result, one end of the rhombus block 12 slides in its groove 16 and drives the rhombus block 12 to rotate in the opposite direction. This causes the other end of the rhombus block 12 to slide in another groove 16 and push the other stop 11. At this time, the two stops 11 slide in the inner side of the pressure cap 3, and the distance between the two stops 11 changes. At this time, the two stops 11 and the two grooves 6 are engaged. At the same time, the pressure cap 3 and the cylinder 1 are fixed together, thus realizing the installation of the pressure cap 3.

[0042] 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.
