Description

Technical Field

[0001] This utility model relates to the field of oil filter technology. Background Technology

[0002] Oil filters are used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from engine oil, thus protecting the engine. For example, Chinese patent CN106150595B provides an automotive oil filter, which includes a first fixed disc, a second fixed disc, a filter element, a support cylinder, and a collar. The collar passes through the vertical cross-section of multiple pleated strips, and multiple limiting blocks are fixed on the collar. The pleated strips are located between two adjacent limiting blocks. Oil filters in the prior art, such as those described above, mainly use folded filter paper for oil filtration. During oil circulation, larger particulate deposits can accumulate. These larger foreign objects easily adhere to and become stuck at the folds of the filter paper, affecting the filtration effect and reducing the filter element's lifespan. Utility Model Content

[0006] The filter annular shell includes a clamping part, and an annular extension is formed at the end of the clamping part, the annular extension abutting against the inner wall of the shell;

[0007] The surface of the annular extension is formed with filter holes;

[0008] The clamping part is pressed between the filter element and the base plate.

[0009] Preferably, a first sealing ring is provided at the contact point between the annular extension and the inner wall of the outer casing.

[0010] Preferably, a bypass valve assembly is provided on the filter annular shell;

[0011] The bypass valve assembly includes a cylindrical shell disposed on the filter annular shell, a spring disposed inside the cylindrical shell, and a valve disposed at the end of the spring, the valve blocking the opening of the cylindrical shell.

[0012] Preferably, a check valve ring is provided on the inner wall of the base plate.

[0013] Preferably, a sealing sleeve structure is formed in the middle of the check valve ring, and the sealing sleeve structure extends into the filter element.

[0014] Preferably, a second sealing ring is provided on the outer side of the base plate.

[0015] Beneficial Effects: This utility model provides an environmentally friendly oil filter element, which includes a housing, a filter element disposed inside the housing, and a base plate disposed at the opening of the housing, the base plate pressing the filter element tightly inside the housing; a filter annular shell is disposed between the base plate and the lower end of the filter element; the filter annular shell includes a pressing part, the end of the pressing part forming an annular extension, the annular extension abutting against the inner wall of the housing; filter holes are formed on the surface of the annular extension; the pressing part is pressed between the filter element and the base plate. In operation, the environmentally friendly oil filter element provided by this utility model allows oil to enter from the oil inlet on the base plate, first passing through the filter holes on the filter annular shell to filter larger impurities, and then passing through the filter paper on the filter element. The filtered oil enters the interior of the filter element and exits from the oil outlet on the base plate. This improvement over existing oil filters removes larger impurities from the oil first, preventing them from adhering to the surface of the filter paper and affecting the filtration effect, thus greatly improving the service life of the oil filter.
