[0021] The following is a further detailed description of the specific implementation methods of the utility model by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model and facilitating its implementation.

[0022] Figure 1 It is a structural schematic diagram of the oil pump filter element structure in an embodiment of the utility model; Figure 2 It is an exploded view of the oil pump filter element structure in the embodiment of the utility model.

[0023] like Figure 1 and Figure 2 As shown, the oil pump filter element structure provided by the utility model comprises a filter element body 10 and an end cover 20. The filter element body 10 is a filter paper structure and is in a wavy cylinder shape.

[0024] Figure 3 It is a bottom view of the upper end cover in the embodiment of the utility model; Figure 4 It is a top view of the lower end cover in the embodiment of the utility model.

[0025] like Figure 3 and Figure 4 As shown, the end caps 20 are arranged at both ends of the filter element body 10, and the end caps 20 include an upper end cap 21 and a lower end cap 22. The end caps 20 are provided with convex ribs 23, and the edges of both ends of the filter element body 10 are connected to the convex ribs 23. The upper end cap 21 is circular, and a first through hole 211 is opened on the upper end cap 21, and the lower end cap 22 is circular, and a second through hole 221 is opened on the lower end cap 22.

[0026] The convex rib 23 includes a first convex rib 231 and a second convex rib 232. The first convex rib 231 is arranged on the upper end cover 21, and the second convex rib 232 is arranged on the lower end cover 22. The first convex rib 231 can strengthen the contact area between the upper end cover 21 and the filter element body 10, and enhance the connection strength between the upper end cover 21 and the filter element body 10, thereby avoiding the problem of the filter element body 10 falling off due to oil pressure at the connection, and extending the service life. The second convex rib 232 can strengthen the contact area between the lower end cover 22 and the filter element body 10, and enhance the connection strength between the lower end cover 22 and the filter element body 10, thereby avoiding the problem of the filter element body 10 falling off due to oil pressure at the connection, and extending the service life.

[0027] like Figure 3As shown, the first rib 231 is annular, and multiple first ribs 231 are evenly distributed on the upper end cover 231. Multiple first ribs 231 are cocentrically distributed with the first through hole 211, thereby further enhancing the connection strength between the upper end cover 21 and the filter element body 10 and further extending the service life.

[0028] like Figure 4 As shown, the second rib 232 is annular, and multiple second ribs 232 are evenly distributed on the lower end cover 22. The multiple second ribs 232 are cocentrically distributed with the second through holes 221, thereby further enhancing the connection strength between the lower end cover 22 and the filter element body 10.

[0029] Since the oil pressure on the outer peripheral surface of the filter element body 10 is the greatest, the intervals between the multiple first ribs 231 gradually decrease in the direction away from the first through hole 211, and the intervals between the second ribs 232 gradually decrease in the direction away from the second through hole 221, so that the distribution of the first ribs 231 and the second ribs 232 is more reasonable, thereby further improving the connection effect of the first ribs 231 and the second ribs 232.

[0030] The intervals between the multiple first ribs 231 form a first collecting groove 233, and the intervals between the multiple second ribs 232 form a second collecting groove 234. The end cover 20 and the filter element body 10 are connected by ultrasonic welding. This welding method has no welding slag and can prevent the oil pump filter element body from polluting the oil. The first collecting groove 233 and the second collecting groove 234 can further prevent external impurities from entering the interior of the oil pump filter element, thereby further improving the filtering effect of the oil pump filter element structure provided by the utility model.
