Description

Technical Field

[0001] This utility model relates to the field of oil filter technology, and more specifically, to a snap-fit ​​oil filter. Background Technology

[0002] Oil filters are an indispensable component in automotive engine maintenance. Their main function is to filter out impurities, gum, and water from the engine oil, ensuring the cleanliness of the oil in the lubrication system and preventing these impurities from damaging the engine's internal components. Traditional oil filters are mostly installed directly inside a one-piece housing, which cannot be opened without damaging it. This makes it inconvenient to disassemble and replace the filter after its lifespan, increasing operating costs. Furthermore, large particles of impurities easily accumulate inside the oil filter, eventually causing blockages and affecting the oil's filtration efficiency. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a snap-fit ​​oil filter element, which solves the technical problem mentioned in the background art that most traditional oil filters are directly installed inside the housing, which is integrally molded and cannot be opened without damaging the housing. This makes it inconvenient to disassemble and replace the filter element in real time after its service life, thus increasing the cost of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​oil filter element, comprising a filter element, an oil inlet pipe slidably disposed inside the filter element, a cap fixedly disposed on the upper end of the outer wall of the oil inlet pipe, a protective shell disposed at the lower end of the cap, the protective shell being located at the outer end of the filter element, a connecting plate fixedly disposed on the upper end face of the protective shell, a snap-fit ​​post disposed on the upper end face of the connecting plate, an arc-shaped hole correspondingly opened on the upper end face of the cap, a through hole opened on one side of the arc-shaped hole and on the upper end face of the cap, and a snap-fit ​​groove opened on the other side, a fixing block disposed on the upper end face of the snap-fit ​​post, a first spring disposed on the lower end face of the fixing block, a snap-fit ​​block fixedly disposed at the lower end of the first spring, the snap-fit ​​block being slidably installed with the snap-fit ​​post and located inside the snap-fit ​​groove, a flange fixedly disposed on the outer wall of the oil inlet pipe, and the flange being fixedly installed with the filter element by bolts.

[0005] The present invention is further provided that the outer wall of the oil inlet pipe is provided with filter holes, the filter holes are provided in multiple and evenly distributed, and the lower end of the oil inlet pipe is provided with a sealing plug, the sealing plug being threadedly connected to the oil inlet pipe, so as to facilitate the filtration of large particles of residue inside the engine oil.

[0006] The present invention is further configured such that a first conical surface is fixedly provided on the upper end surface of the sealing plug, and a second conical surface is provided on the inner wall of the oil inlet pipe at the lower end, wherein the first conical surface is located inside the second conical surface, which facilitates cleaning of the inside of the oil inlet pipe.

[0007] The present invention is further provided with a pin slidingly provided on the outer wall of the cover, and multiple pins are provided in a circular arrangement. A corresponding insertion hole is provided on the outer wall of the connecting plate. One end of each pin passes through the cover and is located inside the insertion hole, which facilitates further fixing of the cover and the connecting plate.

[0008] The present invention is further configured such that a pull block is fixedly provided at the other end of each of the pins, and a second spring is fixedly provided between the pull block and the cover to facilitate pushing the pin into the insertion hole.

[0009] The present invention is further configured such that the diameters of the through hole, the fixing block, the snap-fit ​​block, and the snap-fit ​​groove are equal, which facilitates the installation of the cover and the protective shell.

[0010] The present invention is further configured such that the inclination of the first conical surface and the second conical surface are equal, which facilitates increasing the sealing between the oil inlet pipe and the sealing plug.

[0011] The present invention is further provided with an oil outlet pipe on the outer wall of the protective shell at the lower end, so as to facilitate the discharge of filtered engine oil.

[0012] Compared with the prior art, this utility model provides a snap-fit ​​oil filter element, which has the following beneficial effects:

[0013] By incorporating a filter element, oil inlet pipe, cover, protective shell, connecting plate, snap-fit ​​post, arc-shaped hole, through hole, snap-fit ​​groove, fixing block, first spring, and snap-fit ​​block, the user can pass the snap-fit ​​post and fixing block at the upper end of the protective shell through the through hole and rotate them inside the arc-shaped hole. This allows the snap-fit ​​block to enter the snap-fit ​​groove under the action of the first spring, facilitating the disassembly and fixing of the filter element and protective shell.

[0014] By setting up a flange, filter holes, sealing plug, first conical surface and second conical surface, the filter holes on the oil inlet pipe can filter out the residue in the oil, preventing it from entering the filter element and causing blockage. Users can also disassemble the oil inlet pipe using bolts and flanges, and finally disassemble the sealing plug to facilitate cleaning the inside of the oil inlet pipe.

[0015] By setting up a buckle, a pin, a socket, a pull block, and a second spring, the pin will extend and retract due to the action of the second spring during the process of fixing the buckle and the protective shell until it is aligned with the socket. At this time, one end of the pin will enter the socket to further fix the protective shell and the buckle. Attached Figure Description
