Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filter. Background Technology

[0002] Traditional filters require filter elements (filter paper) to be installed inside to filter the media passing through them. Currently, existing technologies use adhesive to fix the filter elements inside the filter to prevent them from being washed away or deformed. This method of fixing filter elements is only suitable for simple filtration applications, but it has limitations for some special space or operating conditions. For example, for irregularly shaped filters, this fixing method makes installation difficult; under high load or high oil pressure conditions, this fixing method provides insufficient support, making it impossible to maintain the stability of the filter element shape, thus compromising filtration effectiveness. Utility Model Content

[0017] Alternatively, the upper cover may be an integral structure with the plurality of first positioning support columns and the plurality of second positioning support columns.

[0018] In one embodiment, the housing includes a first connecting segment, an arc segment, and a second connecting segment connected in sequence;

[0019] The filter element is folded along the extension direction of the housing and disposed within the filter channel.

[0020] In one embodiment, the housing has a filter medium inlet and a filter medium outlet that communicate with the filter channel.

[0032] This utility model proposes a filter 100.

[0033] Please see Figures 1 to 3 In one embodiment of this utility model, the filter 100 includes a filter channel 11, a positioning support assembly 30, and a filter element 20. The filter channel 11 has a first inner wall 12 and a second inner wall 13 facing each other. The positioning support assembly 30 includes a plurality of first positioning support columns 31 and a plurality of second positioning support columns 32 arranged alternately along the medium flow direction in the filter channel 11. The plurality of first positioning support columns 31 are spaced apart along the first inner wall 12, and the plurality of second positioning support columns 32 are spaced apart along the second inner wall 13. The filter element 20 is disposed in the filter channel 11. The filter element 20 is arranged in a folded shape by alternately passing through the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 along the medium flow direction. The plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 provide positioning support for the filter element 20 at the bending points.

[0034] The filter 100 in this utility model includes a housing 10, a filter channel 11 formed inside the housing 10, and an inlet and an outlet communicating with the filter channel 11. The inlet is used for the medium to be filtered to enter, and the outlet is used for the filtered medium to be discharged. That is, the medium flows from the inlet to the outlet. In this embodiment, the filter channel 11 has a first inner wall 12 and a second inner wall 13 arranged opposite to each other. In this embodiment, a filter element 20 is also provided. The filter element 20 is disposed in the filter channel 11 and is used to purify and filter the medium when it flows through the filter channel 11. To ensure the stability of the filter element 20 during media flow, in this embodiment, a positioning support assembly 30 is also provided within the filter channel 11. The positioning support assembly 30 includes multiple first positioning support columns 31 and multiple second positioning support columns 32. Both the first and second positioning support columns 31 and 32 are disposed between the first inner wall 12 and the second inner wall 13 of the filter channel 11. The first positioning support columns 31 are positioned close to and spaced apart from the first inner wall 12, forming multiple first positioning channels through which the filter element 20 can be bent and folded. The second positioning support columns 32 are positioned close to and spaced apart from the second inner wall 13, forming multiple second positioning channels through which the filter element 20 can be bent and folded. The formation of the multiple first and second positioning channels is primarily for the filter element 20 to alternately pass through along the media flow direction from inlet to outlet, thereby achieving an intermittent support and positioning effect for the filter element 20. In this embodiment, the filter element 20 alternately passes through multiple first positioning channels and multiple second positioning channels in the following manner: the filter element 20 first passes through one of the multiple first positioning channels along the flow direction of the medium, the filter element 20 then passes through one of the multiple second positioning channels, and then the filter element 20 passes through another of the multiple first positioning channels again. The above operation is repeated so that the filter element 20 is arranged in a folded shape within the filter channel 11. By installing a positioning support assembly 30 in the filter channel 11 of the housing 10 of the filter 100, and by placing multiple first positioning support columns 31 in the positioning support assembly 30 close to and spaced apart from the first inner wall 12 to form multiple first positioning channels, and multiple second positioning support columns 32 close to and spaced apart from the second inner wall 13 to form multiple second positioning channels, and then alternately passing the filter element 20 through the multiple first positioning channels and multiple second positioning channels along the flow direction, the filter element 20 is folded and placed in the filter channel 11. This arrangement not only provides spaced positioning support for the filter element 20 and improves the stability of the filter element 20, but also facilitates the installation of the filter element 20 into irregularly shaped filters 100 because the filter element 20 is easy to fold.

[0035] It is worth mentioning that in this embodiment, the filter element 20 can be either filter cotton or filter paper, and there are no further limitations on this.

[0036] For multiple descriptions, there can be two or more, and there is no specific limit to the number of the first positioning support column 31 and the second positioning support column 32.

[0037] In one embodiment, such as Figure 1 As shown, the first inner wall 12 is provided with a plurality of first positioning grooves 141 corresponding one-to-one with a plurality of first positioning support columns 31. The first positioning support column 31 is arranged adjacent to the groove opening of the corresponding first positioning groove 141, and there is a gap between the first positioning support column 31 and the groove opening for the filter element 20 to pass through; and / or, the second inner wall 13 is provided with a plurality of second positioning grooves 142 corresponding one-to-one with a plurality of second positioning support columns 32. The second positioning support column 32 is arranged adjacent to the groove opening of the corresponding second positioning groove 142, and there is a gap between the second positioning support column 32 and the groove opening for the filter element 20 to pass through. Since the filter element 20 is curved in the portion passing through the first positioning channel and the second positioning channel, in order to better accommodate this portion of the filter element 20, in this embodiment, a first positioning groove 141 is recessed on the first inner wall 12. The opening of the first positioning groove 141 is at least partially oriented towards the first positioning support column 31. This arrangement allows the first positioning groove 141 to accommodate the curved portion of the filter element 20 when it is folded by the first positioning support column 31. Furthermore, this arrangement also seals the gap between the curved portion of the filter element 20 and the original first inner wall 12, preventing the medium from flowing directly through the gap to the outlet without passing through the filter element 20 and being discharged through the outlet. Alternatively, in another embodiment, referring to the first positioning groove 141, a second positioning groove 142 corresponding at least partially to the second positioning support column 32 is formed on the second inner wall 13, thus achieving the same effect as described above. Alternatively, the first positioning groove 141 and the second positioning groove 142 in the above two embodiments can be combined in the same solution to achieve better results. Regarding the number of the first positioning groove 141 and the second positioning groove 142, the number of the first positioning groove 141 and the second positioning groove 142 can be set according to the number of the first positioning support column 31 and the second positioning support column 32, and no further restrictions are imposed on this.

[0038] In one embodiment, such as Figure 1 and Figure 2As shown, a plurality of first positioning support columns 31 are arranged at intervals along the flow direction from the inlet to the outlet; and / or, a plurality of second positioning support columns 32 are arranged at intervals along the flow direction from the inlet to the outlet. In this embodiment, the plurality of first positioning support columns 31 are arranged at intervals along the flow direction of the medium within the filter channel 11, that is, arranged at intervals along the extension direction of the filter channel 11. It should be noted that each first positioning support column 31 needs to be close to and spaced apart from the first inner wall 12 of the filter channel 11. In other embodiments, the plurality of second positioning support columns 32 are arranged in the filter channel 11 in a similar manner to the plurality of first positioning support columns 31 described above. The difference is that each second positioning support column 32 needs to be close to the second inner wall 13 of the filter channel 11 and spaced apart from the second inner wall 13. The plurality of first positioning channels formed by the plurality of first positioning support columns 31 and the first inner wall 12 are arranged at intervals along the flow direction, and the plurality of second positioning channels formed by the plurality of second positioning support columns 32 and the second inner wall 13 are also arranged at intervals along the flow direction. This arrangement makes it convenient for the filter element 20 to alternately pass through the plurality of first positioning channels and the plurality of second positioning channels along the flow direction.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, the projection of the first positioning support column 31 from the first inner wall 12 to the second inner wall 13 is located between two adjacent second positioning support columns 32; or, the projection of the second positioning support column 32 from the second inner wall 13 to the first inner wall 12 at least partially overlaps with the first positioning support column 31. To enable the filter element 20 to be positioned and supported by the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 in the above embodiment, in this embodiment, the first positioning support column 31 and the second positioning support column 32 are staggered in the direction from the first inner wall 12 to the second inner wall 13, that is, the projection of the first positioning support column 31 along the direction from the first inner wall 12 to the second inner wall 13 is located between two adjacent second positioning support columns 32. This arrangement makes the installation of the filter element 20 smoother. Alternatively, in other embodiments, the first positioning support column 31 and the second positioning support column 32 are at least partially corresponding in the direction from the first inner wall 12 to the second inner wall 13. Such an arrangement can also achieve the support and positioning of the filter element 20. The positional relationship between the first positioning support column 31 and the second positioning support column 32 in the direction from the first inner wall 12 to the second inner wall 13 is not specifically limited.

[0040] In one embodiment, such as Figure 2As shown, the thickness of each first positioning support column 31 gradually decreases along the direction of the second inner wall 13 toward the first inner wall 12; and / or, the thickness of each second positioning support column 32 gradually decreases along the direction of the first inner wall 12 toward the second inner wall 13. To facilitate folding or bending of the filter element 20 after installation in the first positioning channel, in this embodiment, the thickness of each first positioning support column 31 gradually decreases along the direction of the second inner wall 13 toward the first inner wall 12. Here, the thickness of the first positioning support column 31 is in the same direction as the flow direction of the medium in the above embodiment. This arrangement allows the filter element 20 to be folded or bent more easily via the first positioning support column 31. Alternatively, the thickness of each second positioning support column 32 gradually decreases along the direction of the first inner wall 12 toward the second inner wall 13. Here, the thickness of the second positioning support column 32 is in the same direction as the flow direction of the medium in the above embodiment. This arrangement also allows the filter element 20 to be folded or bent more easily via the second positioning support column 32. Alternatively, both of the above methods can be applied to the same embodiment, which would allow for better folding or bending of the filter element 20 when positioning and supporting it.

[0041] In one embodiment, the housing 10 includes a main body and a top cover. The main body has a filter groove, and the top cover is disposed on the main body to seal the filter groove, forming the filter channel 11. In this embodiment, the housing 10 includes a main body and a top cover (not shown in the figure). The main body forms a filter groove, and the top cover is detachably disposed on the main body to seal the filter groove. The sealed filter groove forms the filter channel 11 in the above embodiment. Regarding the specific connection method between the top cover and the main body, it can be screwed, snap-fitted, or glued, and there is no particular limitation on this. Of course, the main body can be integrally formed or assembled from multiple pieces, and there is also no particular limitation on this.

[0042] In one embodiment, the filter tank has a bottom wall, which is formed by the bottom wall, the first inner wall 12, and the second inner wall 13. One end of each of the first positioning support pillars 31 and the second positioning support pillars 32 is close to the bottom wall, and the other end is close to the top cover. In this embodiment, the filter tank has a bottom wall, which is the bottom of the filter tank. The filter tank is formed by the bottom wall, the first inner wall 12, and the second inner wall 13. In this embodiment, the multiple first positioning support pillars 31 and the multiple second positioning support pillars 32 are all arranged in the housing 10 along the direction from the bottom towards the top cover covering the opening of the filter tank, and are located in the filter channel 11. One end of each of the multiple first positioning support pillars 31 and the multiple second positioning support pillars 32 is located on the bottom wall, and the other end is close to the top cover. The first positioning support pillars 31 and the second positioning support pillars 32 arranged in this way can provide positioning support for the filter element 20 along the direction from the bottom wall to the top cover. In another embodiment, one end of the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 is close to the bottom wall, and the other end is located on the top cover. No further limitations are imposed on this.

[0043] In one embodiment, the main body and the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 are integrally formed; or, the upper cover and the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 are integrally formed. In this embodiment, the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 are integrally formed with the main body. The plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 can be formed by an integral casting process, or they can be welded to the main body later. No further limitations are imposed on this. In another embodiment, the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 are integrated with the top cover. Of course, the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 and the top cover can also be formed by integral casting or by welding later. It is worth mentioning that with this arrangement, before installing the top cover onto the main body, the filter element 20 can be alternately wound around the plurality of first positioning support columns 31 and the plurality of second positioning support columns 32 in the same manner as in the above embodiment, and then the top cover can be closed onto the main body.

[0044] In one embodiment, such as Figure 2As shown, the housing 10 includes a first connecting segment 15, an arc segment 16, and a second connecting segment 17 connected in sequence; the filter element 20 is folded and disposed within the filter channel 11 along the extending direction of the housing 10. In this embodiment, the housing 10 is composed of a first connecting segment 15, an arc segment 16, and a second connecting segment 17 connected in sequence. The inlet can be disposed on the first connecting segment 15 or the second connecting segment 17, while the outlet can be disposed on the first connecting segment 15 or the second connecting segment 17 without an inlet. In this embodiment, the housing 10 is bent. Since the positioning support component 30 in the above embodiment is provided in the filter channel 11 of the housing 10, the filter element 20 can be folded and disposed within the filter channel 11 along the extending direction of the housing 10. By providing the positioning support component 30 in the filter channel 11, the filter element 20 can be installed in housings 10 of different shapes for use. This configuration allows the filter 100 to be set into a suitable shape according to actual conditions, while the filter element 20 can still be positioned and supported in the filter channel 11 by the positioning support component 30, and the filter element 20 can also remain stable when the media impacts.
