[0004] The filter paper in this oil filter element is in a simple folded state. During the oil filtration process, the folded parts of the filter paper will shake due to the impact. Especially in the later stage of use, adjacent filter paper pieces may stick together, affecting normal filtration. Therefore, a reinforced oil filter element is needed. Utility Model Content

[0005] The purpose of this invention is to provide a reinforced oil filter element, which is more stable during the oil filtration process due to the use of multiple first and second reinforcing rods.

[0006] To achieve the above objectives, this utility model provides a reinforced oil filter element, comprising a central cylinder and an annular cap coaxially fixed to both ends of the central cylinder. The central cylinder is covered with folded filter paper. Multiple perforations are evenly distributed on the surface of the central cylinder. The inner diameter of the annular cap is not greater than the inner diameter of the central cylinder, and the outer diameter of the annular cap is not less than the outer diameter of the folded filter paper. A first reinforcing rib extending axially is provided at the inner corner of the folded filter paper, and a second reinforcing rib extending axially is provided at the outer corner of the folded filter paper. A first through hole extending axially is provided on the first reinforcing rib, and a second through hole extending axially is provided on the second reinforcing rib. Multiple third through holes corresponding to the first through holes are provided on the annular cap, and multiple fourth through holes corresponding to the second through holes are provided on the annular cap. A first reinforcing rod is inserted into the first through hole, with both ends of the first reinforcing rod inserted and fixed into the third through holes at both ends. A second reinforcing rod is inserted into the second through hole, with both ends of the second reinforcing rod inserted and fixed into the fourth through holes at both ends.

[0007] Preferably, the inner side of the annular cover is provided with a star-shaped groove that can accommodate the end of the folded filter paper, and the groove wall of the star-shaped groove is in close contact with the outer wall of the folded filter paper.

[0008] Preferably, the inner end of the star-shaped groove is configured to communicate with the central hole of the annular cover, and both ends of the central cylinder can be accommodated in the radial inner end of the star-shaped groove.

[0009] Preferably, the star-shaped groove is provided with an inner groove to accommodate the end of the first reinforcing rib, the third through hole is provided at the inner groove, and the fourth through hole is provided at the outer end of the star-shaped groove.

[0010] Preferably, the outer surface of the inner fold corner of the folded filter paper is an arc surface that fits into the outer wall of the central cylinder.

[0011] Preferably, the leakage hole is a circular hole.

[0012] Preferably, the first through hole and the second through hole have the same diameter.

[0013] According to the above technical solution, this utility model provides a reinforced oil filter element, including a central cylinder and an annular cover coaxially fixed to both ends of the central cylinder. The central cylinder is covered with folded filter paper. Multiple leakage holes are evenly distributed on the surface of the central cylinder. The inner diameter of the annular cover is not greater than the inner diameter of the central cylinder, and the outer diameter of the annular cover is not less than the outer diameter of the folded filter paper. An axially extending first reinforcing rib is provided at the inner corner of the folded filter paper, and an axially extending second reinforcing rib is provided at the outer corner of the folded filter paper. An axially extending first through hole is provided on the first reinforcing rib, and an axially extending second through hole is provided on the second reinforcing rib. Multiple third through holes corresponding to the first through holes are provided on the annular cover, and multiple fourth through holes corresponding to the second through holes are provided on the annular cover. A first reinforcing rod is inserted into the first through hole, and both ends of the first reinforcing rod are inserted and fixed into the third through holes at both ends. A second reinforcing rod is inserted into the second through hole, and both ends of the second reinforcing rod are inserted and fixed into the fourth through holes at both ends.

[0014] This reinforced oil filter element has the following beneficial effects: It improves upon the original annular pleated filter paper by adding a first reinforcing rib at the inner corner of the pleated filter paper and a second reinforcing rib at the outer corner. A first through hole and a second through hole are respectively provided at the first and second reinforcing ribs for the first and second reinforcing rods to pass through. During assembly, the first and second reinforcing rods are inserted into the first and second through holes respectively, and their ends are fixed in the third and fourth through holes. Therefore, the filter paper is more stable when subjected to oil impact, and its folded shape can remain almost unchanged for a longer period, improving the stability of the oil filter element. Because the filter paper's folded shape is stable, adjacent folds will not stick together, resulting in a more stable filtration effect.

[0027] See Figure 1-6 The reinforced oil filter element shown includes a central cylinder 2 and annular caps 1 coaxially fixed to both ends of the central cylinder 2. A folded filter paper 3 is fitted over the central cylinder 2. Multiple perforations 7 are evenly distributed on the surface of the central cylinder 2. The inner diameter of the annular cap 1 is not greater than the inner diameter of the central cylinder 2, and the outer diameter of the annular cap 1 is not less than the outer diameter of the folded filter paper 3. An axially extending first reinforcing rib 4 is provided at the inner corner of the folded filter paper 3, and an axially extending second reinforcing rib 13 is provided at the outer corner of the folded filter paper 3. An axially extending first perforation is provided on the first reinforcing rib 4. Hole 12, the second reinforcing rib 13 is provided with an axially extending second through hole 14, the annular cover 1 is provided with a plurality of third through holes 11 corresponding one-to-one with the first through hole 12, the annular cover 1 is provided with a plurality of fourth through holes 9 corresponding one-to-one with the second through hole 14, a first reinforcing rod 6 is inserted into the first through hole 12, and the two ends of the first reinforcing rod 6 are inserted and fixed in the third through holes 11 at both ends, and a second reinforcing rod 5 is inserted into the second through hole 14, and the two ends of the second reinforcing rod 5 are inserted and fixed in the fourth through holes 9 at both ends.

[0028] Through the implementation of the above technical solution, the reinforced oil filter element is improved based on the original annular pleated filter paper 3. A first reinforcing rib 4 is provided at the inner corner of the pleated filter paper 3, and a second reinforcing rib 13 is provided at the outer corner of the pleated filter paper 3. A first through hole 12 and a second through hole 14 are respectively opened at the first reinforcing rib 4 and the second reinforcing rib 13 for the first reinforcing rod 6 and the second reinforcing rod 5 to pass through. During assembly, the first reinforcing rod 6 and the second reinforcing rod 5 are inserted into the first through hole 12 and the second through hole 14 respectively, and their two ends are fixed in the third through hole 11 and the fourth through hole 9 respectively. Therefore, when the filter paper is impacted by oil, it is more stable, and its folding shape can remain almost unchanged for a longer period of time, which improves the stability of the oil filter element. Because the folding shape of the filter paper is stable, adjacent folds will not stick together, making the filtration effect more stable.

[0029] In this embodiment, the inner side of the annular cover 1 is provided with a star-shaped groove 8 that can accommodate the end of the folded filter paper 3, and the groove wall of the star-shaped groove 8 is in close contact with the outer wall of the folded filter paper 3.

[0031] In this embodiment, the inner end of the star-shaped groove 8 is configured to communicate with the central hole of the annular cover 1, and both ends of the central cylinder 2 can be accommodated in the radial inner end of the star-shaped groove 8. This arrangement allows both ends of the central cylinder 2 to be accommodated within the star-shaped groove 8, and the two ends of the central cylinder 2 to be aligned with the two ends of the folded filter paper 3, thus enabling better assembly of the reinforced oil filter element.

[0032] In this embodiment, the star-shaped groove 8 is provided with an inner groove 10 to accommodate the end of the first reinforcing rib 4, the third through hole 11 is provided at the inner groove 10, and the fourth through hole 9 is provided at the outer end of the star-shaped groove 8. This arrangement allows the end of the first reinforcing rib 4 to be accommodated in the inner groove 10 and its position to be defined, resulting in a more stable installation.

[0033] In this embodiment, the outer surface of the inner fold corner of the folded filter paper 3 is an arc surface 15 that fits against the outer wall of the central cylinder 2. With this arrangement, the arc surface 15 can be supported on the outer wall of the central cylinder 2, making the folded filter paper 3 more stable after installation.

[0034] In this embodiment, to further provide a drain hole 7 structure, the drain hole 7 is a circular hole. Of course, it can also be set as a triangular hole or an elliptical hole, etc., as needed.

[0035] In this embodiment, the first through hole 12 and the second through hole 14 have the same diameter. This implementation allows the first reinforcing rod 6 and the second reinforcing rod 5 to use the same specifications. After the two ends of the first reinforcing rod 6 and the second reinforcing rod 5 are inserted into the corresponding third through hole 11 and fourth through hole 9, they can be fixed to the corresponding annular cover 1 by glue or welding.
