Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a filter structure. Background Technology

[0002] A filter element is a core component used to filter impurities in fluids, and it is widely used in industrial, medical, and household applications. Its core principle is to separate particles, microorganisms, and chemical substances from the fluid through physical interception, adsorption, or chemical reaction, ensuring the purity of the medium and protecting downstream equipment or meeting specific usage requirements.

[0003] Currently, traditional filter cartridges typically use a threaded connection to fix the filter screen and the filter element. While this structure is simple, after long-term use, corrosion at the threaded connection points can cause the filter screen and filter element to become stuck, making it difficult to remove the filter screen. Filter screens that haven't been replaced for a long time may accumulate impurities, reducing filtration efficiency. For some filter cartridges with difficult-to-remove screens, users may damage them during forceful removal, rendering them unusable. Filter cartridges with inaccessible screens can only be discarded, resulting in resource waste. Summary of the Invention

[0004] The purpose of this invention is to propose a filter element structure to solve the problems mentioned in the background art.

[0005] Therefore, one objective of this utility model is to propose a filter element structure that optimizes the filter element fixing method to a snap-fit ​​connection structure, thereby solving the problem of difficulty in removing the filter element caused by corrosion due to long-term use of traditional threaded connection methods.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a filter element structure, including a filter element and a fixing mechanism. The fixing mechanism is disposed on the filter element and includes a first spring, a limiting block and a slider. A groove is formed on the inner wall of the filter element, the first spring is disposed in the groove, the limiting block is disposed at the other end of the first spring, and the slider is disposed on the outer wall of the filter element.

[0007] In addition, the filter element structure proposed above according to this utility model may also have the following additional technical features: Specifically, a control ring is fitted around the outside of the filter element, and the outer wall of the limiting block passes through the sliding groove and is connected to the inner wall of the control ring.

[0008] Specifically, the filter element is fitted with a sealing sleeve.

[0009] Specifically, the filter element includes a housing, a filter screen, and a cover plate. The filter screen is disposed inside the housing, and the cover plate is disposed on the housing.

[0010] Specifically, the filter element is provided with an installation assembly, which includes a connecting pipe, a ball bearing, a limiting ring, a second spring, a fixing ring, and a protective shell. The connecting pipe is located at one end of the shell, and a limiting hole is opened on the outer wall of the connecting pipe. The ball bearing is located in the limiting hole, the limiting ring is located on the outer wall of the connecting pipe, the second spring is sleeved on the outside of the connecting pipe, the fixing ring is sleeved on the outside of the connecting pipe, and the two ends of the second spring are respectively connected to the limiting ring and the fixing ring. The protective shell is located on the outside of the fixing ring, and a groove is opened on the outer wall of the shell.

[0011] Specifically, a limit groove is provided on the outer wall of the shell, and a locking block is provided inside the connecting pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model optimizes the filter element fixing method to a snap-fit ​​connection structure. The snap-fit ​​connection structure is different from the traditional bolt fixing, which can prevent internal corrosion that would prevent the filter screen from being properly disassembled and installed. It solves the problem of difficulty in removal caused by corrosion of traditional threaded connection methods after long-term use. At the same time, with the setting of the installation components, the filter element can be installed inside the pipe or at the pipe outlet according to the actual use needs.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] A filter element structure according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, a filter element structure includes a filter element 1 and a fixing mechanism 2.

[0019] The fixing mechanism 2 is installed on the filter element 1. The fixing mechanism 2 includes a first spring 22, a limiting block 23 and a slider 24.

[0020] The inner wall of the filter element 1 is provided with a sliding groove 21, the first spring 22 is disposed in the sliding groove 21, the limiting block 23 is disposed at the other end of the first spring 22, the slider 24 is disposed on the outer wall of the filter element 1, the filter element 1 is covered with a control ring 25, and the outer wall of the limiting block 23 passes through the sliding groove 21 and is connected to the inner wall of the control ring 25. The filter element 1 is covered with a sealing sleeve 26.

[0021] It should be noted that the slide groove 21 described in this embodiment is formed on the inner wall of the cover plate 13, and the slide groove 21 is L-shaped. Its main function is to facilitate the fixing of the slider 24 by the limiting block 23. The slider 24 is set on the outer wall of the housing 11.

[0022] Specifically, when the filter element 1 needs to be assembled for use in a pipeline, one or more filter screens 12 of different specifications can be placed sequentially inside the housing 11. Then, the slider 24 on the outer wall of the housing 11 is aligned and inserted along the groove 21 in the cover plate 13. At this time, the slider 24 will push the limiting block 23, and the slider 24 will squeeze the first spring 22. At this time, the first spring 22 is compressed and stored. During the movement of the limiting block 23, the control ring 25 will move. When the limiting block 23 is pushed to a certain position, the corner of the L-shaped groove 21 will be exposed. Then, the housing 11 is rotated to rotate the slider 24 to the corner of the L-shaped groove 21. At this time, the slider 24 will move away from the limiting block 23. The first spring 22, which is no longer squeezed by the limiting block 23, will pop the limiting block 23 out along the direction defined by the groove 21 during the reset process, so that the limiting block 23 is on the side wall of the slider 24, thereby restricting the movement of the slider 24.

[0023] Next, the sealing sleeve 26 can be placed on the outside of the filter element 1 for secondary fixation. Then the filter element 1 can be placed inside the pipe. During use, the fluid flows in through one end of the filter element 11 and flows out from the other end of the filter element 1 after filtration, thus completing the filtration.

[0024] When it is necessary to disassemble the filter element 1, the sealing sleeve 26 is removed from the outside of the filter element 1. Then, the relevant personnel pull the control ring 25. The control ring 25 drives the limiting block 23 along the direction defined by the slide groove 21. At the same time, the limiting block 23 will compress the first spring 22 during the movement, and the corner of the slide groove 21 will be gradually exposed during the movement of the limiting block 23. At this time, the first spring 22 is compressed. Then, the housing 11 can be rotated in the opposite direction and the control ring 25 can be released. At this time, the first spring 22 begins to return to its original position, and the limiting block 23 at one end of the first spring 22 pops out along the direction defined by the slide groove 21. At the same time, the limiting block 23 is raised to push the slider 24, so that it slides out of the slide groove 21, thereby completing the disassembly.

[0025] In one embodiment of this utility model, such as Figure 1 As shown, the filter element 1 includes a housing 11, a filter screen 12, and a cover plate 13. The filter screen 12 is disposed inside the housing 11, and the cover plate 13 is disposed on the housing 11.

[0026] Specifically, when filter element 1 is needed, one or more filter screens 12 of different specifications are placed inside housing 11 and fixed by cover plate 13, and then filter element 1 can be installed to the part where it is needed.

[0027] In one embodiment of this utility model, such as Figure 3 As shown, the filter element 1 is equipped with an installation component 3.

[0028] Mounting assembly 3 includes a connecting pipe 31, a ball bearing 33, a limiting ring 34, a second spring 35, a retaining ring 36, and a protective shell 37.

[0029] A connecting tube 31 is disposed at one end of the housing 11. A limiting hole 32 is formed on the outer wall of the connecting tube 31. A ball bearing 33 is disposed in the limiting hole 32. A limiting ring 34 is disposed on the outer wall of the connecting tube 31. A second spring 35 is sleeved on the outside of the connecting tube 31. A fixing ring 36 is sleeved on the outside of the connecting tube 31. The two ends of the second spring 35 are respectively connected to the limiting ring 34 and the fixing ring 36. A protective shell 37 is disposed on the outside of the fixing ring 36. A slot 38 is formed on the outer wall of the housing 11. A limiting groove 39 is formed on the outer wall of the housing 11. A locking block 310 is disposed inside the connecting tube 31.

[0030] It should be noted that the connecting pipe 31 described in this embodiment is an independent component that needs to be pre-fixed to an external pipe.

[0031] Specifically, when the filter element 1 needs to be installed at the outlet of the pipe, the operator can fix the connecting pipe 31 at the outlet, and then pull the protective shell 37 upward. The protective shell 37 pulls the fixing ring 36, causing the fixing ring 36 to move away from the opening of the limiting hole 32 on the outer wall of the connecting pipe 31, thereby releasing the restriction on the ball 33. At the same time, the fixing ring 36 will squeeze the second spring 35 during the movement. At this time, the second spring 35 stores and compresses, and then the housing 11 is inserted into the connecting pipe 31, and the locking block 310 on the inner wall of the connecting pipe 31 will be locked into the limiting groove 39 on the outer wall of the housing 11, thereby limiting the housing 11. Furthermore, when the housing 11 is inserted into the connecting tube 31, the outer wall of the housing 11 will first push the ball 33 outward along the direction defined by the limiting hole 32. When the side wall of the limiting groove 39 on the outer wall of the housing 11 contacts the locking block 310 in the connecting tube 31, the locking groove 38 on the outer wall of the housing 11 is aligned with the upper limiting hole 32 of the connecting tube 31. Then, the protective shell 37 is released. At this time, the second spring 35, which is no longer compressed, will push the fixing ring 36 back during the reset process for synchronous reset. After reset, the fixing ring 36 is located at the opening of the limiting hole 32. At this time, the inner wall of the fixing ring 36 will contact the ball 33 and push it along the direction defined by the limiting hole 32. After moving, part of the ball 33 will be stuck in the groove 38 on the outer wall of the protective shell 37, and the other part of the ball 33 will contact the inner wall of the fixing ring 36. At this time, the position of the ball 33 will be fixed and cannot be moved. At this time, the shell 11 will be fixed at one end of the connecting pipe 31. During the process of using the filter element 1 for filtration, the fluid enters the shell 11 through the connecting pipe 31, is filtered, and then flows out from the other end of the shell 11.

[0032] Working principle: When the filter element 1 needs to be assembled for use in the pipeline, the operator places one or more filter screens 12 of different specifications inside the housing 11, then aligns and inserts the slider 24 on the outer wall of the housing 11 with the groove 21 in the cover plate 13. At this time, the slider 24 will push the limiting block 23 to compress the first spring 22. The first spring 22 stores and compresses. At the same time, during the movement of the limiting block 23, its side wall will penetrate the groove 21 and drive the control ring 25 to move. When the limiting block 23 is pushed to a certain position, the corner of the groove 21 will be exposed. At this time, the housing 11 is rotated to rotate the slider 24 to the corner. The first spring 22, which is no longer compressed by the limiting block 23, will eject the limiting block 23 along the direction defined by the groove 21 during the reset process, so that the limiting block 23 is on the side wall of the slider 24, thereby restricting the movement of the slider 24. Then, the sealing sleeve 26 is placed on the outside of the filter element 1 to fix it for a second time, and then the filter element 1 can be put into the pipeline. During use, the fluid flows in through one end of the filter element 11 and flows out from the other end of the filter element 1 after filtration.

[0033] When the filter element 1 needs to be disassembled, the sealing sleeve 26 is removed from the outside of the filter element 1. Then, the relevant personnel pull the control ring 25. The control ring 25 drives the limiting block 23 to squeeze the first spring 22 along the direction defined by the slide groove 21, and exposes the corner of the slide groove 21. At this time, the first spring 22 stores and compresses. Then, the housing 11 is rotated in the opposite direction and the control ring 25 is released. At this time, the first spring 22 begins to reset and the limiting block 23 at one end of the first spring 22 is ejected along the direction defined by the slide groove 21. At the same time, the limiting block 23 is raised to push the slider 24, so that it slides out of the slide groove 21, thereby completing the disassembly.

[0034] When the filter element 1 needs to be installed at the outlet of the pipe, the operator can fix the connecting pipe 31 at the outlet, and then pull the protective shell 37 upwards. The protective shell 37 pulls the fixing ring 36, causing the fixing ring 36 to move away from the opening of the limiting hole 32 on the outer wall of the connecting pipe 31, thereby releasing the restriction on the ball 33. At the same time, the fixing ring 36 will simultaneously squeeze the second spring 35 during the movement. At this time, the second spring 35 stores and compresses, and then the housing 11 is inserted into the connecting pipe 31, so that the locking block 310 on the inner wall of the connecting pipe 31 will be locked into the limiting groove 39 on the outer wall of the housing 11, thereby limiting the housing 11. When the housing 11 is inserted into the connecting pipe 31, the outer wall of the housing 11 will first push the ball 33 outwards along the direction limited by the limiting hole 32. Then, when the side wall of the limiting groove 39 on the outer wall of the housing 11 is locked into the locking block in the connecting pipe 31, the ball 33 will be pushed outwards. When contact 310 occurs, the groove 38 on the outer wall of the housing 11 aligns with the upper limit hole 32 of the connecting pipe 31. Then, the protective housing 37 is released. At this time, the second spring 35, which is no longer compressed, will push the fixing ring 36 back during the reset process for synchronous reset. After reset, the fixing ring 36 is located at the opening of the limit hole 32. At this time, the inner wall of the fixing ring 36 will contact the ball 33 and push it along the direction defined by the limit hole 32. After moving, part of the ball 33 will be stuck in the groove 38 on the outer wall of the protective housing 37, and the other part of the ball 33 will contact the inner wall of the fixing ring 36. At this time, the position of the ball 33 will be fixed and cannot be moved. At this time, the housing 11 will be fixed at one end of the connecting pipe 31. During the filtration process using the filter element 1, the fluid enters the housing 11 through the connecting pipe 31 and then flows out from the other end of the housing 11 after filtration is completed.
