Fixing plates are provided on the inner surfaces of both the bottom plate and the top plate.

[0004] However, the above structure still has some shortcomings. Since the filter element is a consumable, it is inevitable to disassemble it for maintenance or cleaning after long-term use. Because the above filter element structure is not conducive to relatively independent disassembly, it is difficult to disassemble it individually in the later stage, which will reduce the effect of individual disassembly and cleaning of the filter element in the later stage. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a self-cleaning nylon membrane filter element to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A self-cleaning nylon membrane filter element includes a base, a support seat snapped onto the top of the base, a first slot formed at the top of the base, a second slot formed on the inner wall of the first slot, a circular groove formed at the bottom inner side of the first slot, a first locking block matching the first slot fixedly connected to the bottom of the support seat, a second locking block matching the second slot fixedly connected to the outer side of the first locking block, the second locking block snapping into the inner side of the circular groove, a first filter element fixedly connected to the top of the support seat, an mounting plate snapped onto the top of the first filter element, a second filter element fixedly connected to the bottom of the mounting plate, a connecting plate fixedly connected to the bottom of the second filter element, and the bottom of the connecting plate snapping into the top of the support seat.

[0008] As a preferred technical solution, a retaining spring that matches the second retaining block is installed at the bottom inner side of the circular groove. The bottom end of the second retaining block is engaged with the top end of the retaining spring, and the second retaining block is engaged with the inner side of the circular groove through the retaining spring.

[0009] As a preferred technical solution, a rubber pad is fixedly connected to the top of the base, the first slot is located on the inner side close to the rubber pad, and the top of the rubber pad is in contact with the bottom of the support.

[0010] As a preferred technical solution, a protective sleeve is fixedly connected to the top of the base. The protective sleeve is made of rubber material, and a rubber pad is located on the inner side of the protective sleeve, with the inner side of the protective sleeve in contact with the outer side of the support base.

[0011] As a preferred technical solution, a positioning block is fixedly connected to the top of the support base, and a positioning groove matching the positioning block is opened at the bottom of the connecting plate. The positioning block is engaged with the inside of the positioning groove. A limit groove is opened at the top of the first filter element, and a limit block matching the limit groove is fixedly connected to the bottom of the mounting plate. The limit block is engaged with the inside of the limit groove.

[0012] As a preferred technical solution, a slider is slidably connected to the outer wall of the first filter element, and a groove matching the slider is opened on the outer wall of the first filter element. The slider is slidably connected to the outer wall of the first filter element through the groove. A support rod is snapped into the front side of the slider, and a cleaning cotton is fixedly connected to the rear side of the support rod.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, during use, the first locking block facilitates the insertion of the second locking block into the circular groove. Then, the first filter element is slightly rotated to adjust the angle of the second locking block to a position that does not correspond to the second locking groove. This effectively engages the support base and the first filter element to prevent displacement. When it is necessary to disassemble and clean it separately later, the user only needs to rotate the first filter element again to adjust the angle of the second locking block to a position that corresponds to the second locking groove. This allows the support base and the first filter element to be removed directly, achieving the effect of convenient and quick disassembly and cleaning of the first filter element.

[0016] Secondly, because the surface of the first filter element has multiple filter holes, during wiping and cleaning, the contaminants wiped off the surface of the first filter element can easily be wiped back into the holes. The user can slide the slider through the groove, which can move the support rod together, and thus move the cleaning cotton. With the cooperation of water and cleaning cotton, the surface of the first filter element can be wiped evenly. At the same time, the cleaning cotton also has a good dilution ability to prevent the wiped contaminants from re-entering the filter holes, thereby effectively improving the cleaning efficiency of the first filter element. In addition, the support rod is in a snap-fit ​​state, which also makes it easy for the user to directly disassemble it for maintenance or cleaning later. Attached Figure Description

A first locking block 9 matching the first slot 3 is fixedly connected to the bottom of the support seat 8, and a second locking block 10 matching the second slot 4 is fixedly connected to the outer side of the first locking block 9. The second locking block 10 snaps into the inner side of the circular groove 5. A first filter element 11 is fixedly connected to the top of the support seat 8, a mounting plate 12 is snapped onto the top of the first filter element 11, a second filter element 13 is fixedly connected to the bottom of the mounting plate 12, and a connecting plate 14 is fixedly connected to the bottom of the second filter element 13. The first filter element 10 is snapped onto the top of the support base 8. During use, to prevent the support base 8 from falling off, the second snapping block 10 is inserted into the circular groove 5 via the first snapping block 9. Then, the first filter element 11 is slightly rotated to rotate the support base 8, thereby adjusting the angle of the second snapping block 10. The angle of the second snapping block 10 is adjusted so that it does not correspond to the second slot 4, thus effectively snapping the support base 8 and the first filter element 11 together to prevent displacement. When it is necessary to remove them separately for cleaning later, the user only needs to rotate the first filter element 11 again and adjust the angle of the second snapping block 10 to the corresponding position of the second slot 4, so that the support base 8 and the first filter element 11 can be directly removed for later cleaning or maintenance.

[0026] refer to Figure 1 and Figure 2 A retaining spring 6 matching the second retaining block 10 is installed at the bottom inner side of the circular groove 5. The bottom end of the second retaining block 10 is engaged with the top end of the retaining spring 6. The second retaining block 10 is engaged with the inner side of the circular groove 5 through the retaining spring 6. Due to the presence of the retaining spring 6, the retaining spring 6 can engage the second retaining block 10 at the point, thereby improving the stability of the engagement of the support seat 8 at the point and effectively improving the stability of the support seat 8 at the point.

[0027] refer to Figure 2 A rubber pad 7 is fixedly connected to the top of the base 1. The first slot 3 is located on the inner side close to the rubber pad 7. The top of the rubber pad 7 is in contact with the bottom of the support seat 8. Due to the presence of the rubber pad 7, the rubber product has good anti-slip ability and rubber elasticity. While preventing the support seat 8 from sliding on its own, the downward pressing of the support seat 8 can also improve the stability of the second slot 10 being inserted into the inner side of the circular slot 5.

[0028] refer to Figure 1 and Figure 2The top of the base 1 is fixedly connected to a protective sleeve 2, which is made of rubber material. The rubber pad 7 is located on the inner side of the protective sleeve 2, and the inner side of the protective sleeve 2 is in contact with the outer side of the support seat 8. Due to the presence of the protective sleeve 2, it can not only protect the outer side of the support seat 8, but also play a good sealing and dustproof role, thereby improving the cleanliness of the overall filter element.

[0029] refer to Figures 1 to 5 A positioning block 16 is fixedly connected to the top of the support base 8. A positioning groove 15 matching the positioning block 16 is opened at the bottom of the connecting plate 14. The positioning block 16 is snapped into the inside of the positioning groove 15. A limiting groove 18 is opened at the top of the first filter element 11. A limiting block 17 matching the limiting groove 18 is fixedly connected to the bottom of the mounting plate 12. The limiting block 17 is snapped into the inside of the limiting groove 18. Due to the presence of the positioning block 16, the snapping of the positioning block 16 can effectively snap the connection of the connecting plate 14, which can effectively improve the stability of the second filter element 13. The snapping of the limiting block 17 can effectively improve the stability of the connection of the mounting plate 12. At the same time, the positioning groove 15 and the limiting groove 18 also facilitate the user to disassemble the first filter element 11 and the second filter element 13 later for separate maintenance or cleaning.

[0030] refer to Figures 1 to 6 A slider 20 is slidably connected to the outer wall of the first filter element 11. A groove 19 matching the slider 20 is provided on the outer wall of the first filter element 11. The slider 20 is slidably connected to the outer wall of the first filter element 11 through the groove 19. A support rod 22 is snapped into the front side of the slider 20, and a cleaning cotton 24 is fixedly connected to the rear side of the support rod 22. The rear side of the cleaning cotton 24 is in contact with the outer wall of the first filter element 11. Because the surface of the first filter element 11 has multiple filter holes, during wiping and cleaning, the contaminants wiped on the surface of the first filter element 11 can easily be wiped back into the holes. The user can slide the slider 20 through the groove 19. The slider 20 can drive the support rod 22 to move together, which in turn can drive the cleaning cotton 24 to move. With the cooperation of the water source and the cleaning cotton 24, the surface of the first filter element 11 can be wiped evenly. At the same time, the cleaning cotton 24 also has a good dilution ability to prevent the wiped contaminants from re-entering the filter holes, thereby effectively improving the cleaning efficiency of the first filter element 11.

[0031] refer to Figure 3 and Figure 6 The slider 20 has a third slot 21 on its front side. The support rod 22 has a third block 23 that matches the third slot 21 fixedly connected to its rear side. The third block 23 is engaged with the inner side of the third slot 21. The support rod 22 is engaged with the front side of the slider 20 through the third slot 21 and the third block 23. Because the support rod 22 is engaged, it is convenient for the user to disassemble it separately for maintenance later.

[0032] Operating principle and advantages: During use, to prevent the support base 8 from falling off, the second locking block 10 is inserted into the circular groove 5 via the first locking block 9. Then, the first filter element 11 is slightly rotated to rotate the support base 8, thereby adjusting the angle of the second locking block 10. Adjusting the angle of the second locking block 10 to a position where it does not correspond to the second slot 4 effectively engages the support base 8 and the first filter element 11, preventing displacement. When it needs to be disassembled for cleaning later, the user simply rotates the first filter element 11 again to adjust the angle of the second locking block 10 to correspond to the second slot 4. The corresponding positions allow for direct removal of the support base 8 and the first filter element 11 for later cleaning or maintenance. Due to the presence of the retaining spring 6, the second retaining block 10 can be engaged a second time, further enhancing the stability of the support base 8 engagement and effectively improving the stability of the support base 8's engagement points. The presence of the rubber pad 7 provides excellent anti-slip properties and elasticity, preventing the support base 8 from sliding on its own. The downward pressure of the support base 8 also further enhances the stability of the second retaining block 10 engaging the inner side of the circular groove 5. The presence of the protective sleeve 2 allows for... While protecting the outer perimeter of the support base 8, it also provides a good sealing and dustproof effect, thereby improving the overall cleanliness of the filter element. Due to the presence of the positioning block 16, its engagement effectively engages the connecting plate 14, improving the stability of the second filter element 13. The engagement of the limiting block 17 effectively improves the stability of the mounting plate 12. Simultaneously, the positioning groove 15 and limiting groove 18 facilitate the user's later disassembly of the first filter element 11 and the second filter element 13 for individual maintenance or cleaning. Because the surface of the first filter element 11 has multiple filter holes, wiping and cleaning... During the cleaning process, contaminants wiped from the surface of the first filter element 11 can easily be wiped back into the pores. The user can slide the slider 20 through the slide groove 19. The slider 20 can move the support rod 22 together, which in turn can move the cleaning cotton 24. With the cooperation of the water source and the cleaning cotton 24, the surface of the first filter element 11 can be wiped evenly. At the same time, the cleaning cotton 24 also has a good dilution ability to prevent the wiped contaminants from re-entering the filter pores, thereby effectively improving the cleaning efficiency of the first filter element 11. Since the support rod 22 is in a snap-fit ​​state, it is convenient for the user to disassemble it separately for maintenance later.
