[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] In order to facilitate accurate installation of the filter element and the base, this embodiment provides a first filter element, a filter component and a filter assembly. Figures 1 to 9 The specific contents of this embodiment are described in detail.

[0041] like Figures 1 to 4As shown, the first filter element 1 in this embodiment includes a first end cap 11, a filter medium 12, a first center tube 13, and a second end cap 14. The first end cap 11 and the second end cap 14 are respectively disposed at opposite ends of the first center tube 13 and are coaxially arranged. The filter medium 12 is sleeved onto the first center tube 13. A first filter element connector 111 is disposed eccentrically on the side of the first end cap 11 away from the filter medium 12. The first filter element connector 111 is in communication with the first center tube 13.

[0042] In short, the oil to be treated passes through the filter medium 12 and enters the first central tube 13. The clean oil is discharged through the first filter element connector 111. Due to the eccentric design of the first filter element connector 111, it can only be assembled into the corresponding position of the oil outlet pipe 42 in the base 4. If the first filter element 1 deflects, the first filter element connector 111 will be prevented from docking with the oil outlet pipe 42 in the base 4, thereby improving the installation precision and accuracy of the first filter element 1.

[0043] Furthermore, a plurality of guide ribs 113 are provided at intervals along the circumference of the outer edge of the first end cap 11. The addition of the guide ribs 113 not only facilitates the insertion of the first filter element 1 into the relatively deep inner cavity 41 of the base 4, but also prevents the first end cap 11 from colliding with the inner cavity 41 of the base 4.

[0044] Furthermore, a first annular glue injection groove 114 is provided on a side of the first end cap 11 close to the filter medium 12, and one end of the filter medium 12 is bonded to the first annular glue injection groove 114, and / or a second annular glue injection groove 141 is provided on a side of the second end cap 14 close to the filter medium 12, and the other end of the filter medium 12 is bonded to the second annular glue injection groove 141. The addition of the first annular glue injection groove 114 and the second annular glue injection groove 141 facilitates the secure bonding of the opposite ends of the filter medium 12 to the first end cap 11 and the second end cap 14, respectively.

[0045] Furthermore, a handle 142 is rotatably provided on a side of the second end cap 14 away from the filter medium 12. By adding the handle 142, it is convenient to take and put the first filter element 1.

[0046] Furthermore, an annular sealing limiting groove 1111 is provided on the outer wall surface of the first filter element joint 111, and the annular sealing limiting groove 1111 is used to set the sealing ring 3. By adding the annular sealing limiting groove 1111, the installation of the sealing ring 3 is facilitated and the connection sealing is improved.

[0047] This embodiment also provides a filter assembly, which includes a second filter element 2 and the first filter element 1 mentioned above. Figure 3 Combine Figure 5As shown, a second filter element connector 143 is provided at the center of the second end cap 14. One end of the second filter element connector 143 is connected to the first central tube 13, and the other end of the second filter element connector 143 is connected to the second central tube of the second filter element 2. Docking the first filter element 1 and the second filter element 2 not only improves the installation accuracy of the filter assembly and the base 4, but also improves the filtration efficiency.

[0048] This embodiment also provides a filter assembly 100, which includes a sealing ring 3, a base 4 having an inner cavity 41 and the above-mentioned filter assembly. Figures 1 to 8 As shown, an oil outlet pipe 42 is provided within the base 4, and an oil outlet connector 421 is provided on the oil outlet pipe 42. The first filter element connector 111 of the first filter element 1 is plugged into the oil outlet connector 421, and the sealing ring 3 is located between the outer wall surface of the first filter element connector 111 and the outer wall surface of the oil outlet connector 421. This not only improves the installation accuracy of the filter element, but also ensures the sealing of the connection between the filter assembly and the oil outlet connector 421, preventing oil leakage.

[0049] For example, Figure 2 Combine Figure 9 As shown, a slot 112 is provided on the side of the first end cap 11 away from the filter medium 12, and a latching protrusion 4211 is provided on the oil outlet connector 421. The latching protrusion 4211 is plugged into the slot 112 of the first end cap 11 of the first filter element 1. The addition of the slot 112 and the latching protrusion 4211 further improves the stability of the connection between the first end cap 11 and the oil outlet pipe 42.

[0050] Alternatively, as Figures 7 to 9 As shown, the inner diameter of the inner cavity 41 of the base 4 gradually decreases toward the oil outlet pipe 42, forming a tapered structure. The inner hole of the oil outlet connector 421 is a stepped hole 4212. The inner wall of the base 4 is thin at the top and thick at the bottom. The tapered structure of the inner cavity 41 facilitates the guidance of the filter assembly into the inner cavity 41. By machining the stepped hole 4212 within the oil outlet connector 421, the inner diameter of the upper hole of the stepped hole 4212 is larger than the inner diameter of the lower hole of the stepped hole 4212, which facilitates the guidance of the first filter element connector 111 through the upper hole of the stepped hole 4212 and into the lower hole of the stepped hole 4212.

[0051] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
