Description

Technical Field

[0001] This utility model relates to the field of engine lubrication system technology, and in particular to an engine filter that is easy to disassemble and install. Background Technology

[0002] Oil filters can filter out impurities such as metal shavings, dust, carbon deposits oxidized at high temperatures, and gummy deposits during engine operation. They are an important part of cleaning the engine lubrication system and must be replaced every time the engine oil is changed. However, in the actual process of removing and installing oil filters, the narrow area at the rear of the filter usually requires special tools and is time-consuming, which is not conducive to improving work efficiency.

[0003] Furthermore, existing oil filters are installed by screwing them into the corresponding positions using a threaded connection to ensure the oil filter is connected. This means that additional tools are needed for disassembly.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] See Figure 1 , Figure 2 and Figure 4This utility model provides an easy-to-install engine filter, which includes a housing 3 with a plug-in portion 31 at the top. The housing 3 is connected to a predetermined mounting portion 1 inside the oil pan 11, thereby enabling normal installation of the housing 3. A filter element 2 is inserted into the housing 3, and a limiting portion is provided at the top of the filter element 2. The limiting portion abuts against the top of the housing 3, and the limiting portion cooperates with the housing 3 to seal the housing 3, preventing liquid inside the housing 3 from leaking between the housing 3 and the filter element 2, thus affecting the use of the filter. The mounting portion 1 is located at a predetermined position in the engine oil pan 11, and the bottom of the mounting portion 1 has a snap-fit ​​groove 13 corresponding to the plug-in portion 31. The plug-in portion 31 is inserted into the snap-fit ​​groove 13 to fix the housing 3 onto the engine oil pan 11, ensuring that the housing 3 can be quickly installed into the oil pan 11, facilitating subsequent cleaning and replacement of the filter.

[0021] In one embodiment, combined with Figure 3 To ensure the proper installation and use of the filter element 2, a limiting plate is provided on the top of the filter element 2. The limiting plate abuts against the top of the housing 3, ensuring that the filter element 2 can be quickly installed into the housing 3 during installation. At the same time, the top of the limiting plate is pressed against the bottom of the mounting part 1 during installation. A filter screen 23 is provided at the bottom of the limiting plate. The limiting plate is provided with an oil inlet 21 and an oil outlet 22 that communicate with the inside and outside of the filter screen 23, respectively, to ensure the normal oil inlet and outlet of the filter and the normal filtration of the engine oil.

[0022] Specifically, to ensure effective cooperation between the oil inlet pipe 15 and the oil outlet pipe 16 during installation, the bottom of the mounting part 1 is provided with an oil inlet pipe 15 and an oil outlet pipe 16 corresponding to the oil inlet port 21 and the oil outlet port 22. When the oil inlet pipe 15 and the oil outlet pipe 16 are inserted into the oil inlet port 21 and the oil outlet port 22, they restrict the position of the filter element 2. This ensures that when the rotating housing 3 can be inserted into the wedge groove 14, the oil inlet pipe 15 and the oil outlet pipe 16 restrict the position of the filter element 2, thereby ensuring the sealing effect of the filter element 2. The oil inlet port 21 and the oil outlet port 22 on the filter element 2 cooperate and seal with the oil inlet pipe 15 and the oil outlet pipe 16. At the same time, the inside of the oil inlet port 21 and the oil outlet port 22 is provided with a sealing ring to ensure the sealing cooperation effect between the oil pipe and the port.

[0023] In one embodiment, combined with Figure 4 To further optimize the sealing and installation effect between the housing 3 and the filter element 2, a sealing groove 33 is provided on the top of the housing 3, and the limiting plate is fastened inside the sealing groove 33. The limiting plate and the sealing groove 33 cooperate to seal the inside of the housing 3. A sealing ring or sealing gasket is provided inside the sealing groove 33 to ensure the sealing effect.

[0024] The deformation of the gasket or sealing ring itself ensures the seal between the limiting plate and the sealing groove 33, preventing oil leakage.

[0025] In one embodiment, in order to ensure the installation and sealing effect between the housing 3 and the mounting part 1, the top of the housing 3 is provided with a sealing protrusion 32, and the insertion part 31 is inserted into the top of the sealing protrusion 32. When the insertion part 31 is inserted into the inside of the snap-fit ​​groove 13, the sealing protrusion 32 and the mounting part 1 cooperate to seal, thereby ensuring the sealing effect between the sealing protrusion 32 and the mounting part 1, preventing oil leakage between the housing 3 and the mounting part 1, and affecting the oil filtration effect.

[0026] Specifically, in an exemplary embodiment, the bottom of the mounting part 1 is provided with a sealing ring 12, the sealing protrusion 32 is in close contact with the sealing ring 12, a sealing gasket is provided between the sealing protrusion 32 and the sealing ring 12, the bottom of the snap-fit ​​groove 13 is provided with a wedge groove 14, the insertion part 31 is inserted into the snap-fit ​​groove 13 and then rotated into the wedge groove 14 so that the sealing protrusion 32 and the sealing ring 12 are pressed and sealed. The insertion part 31 can be a protruding insert plate structure to ensure that it can be inserted into the interior of the wedge groove 14 and the snap-fit ​​groove 13, thereby ensuring the clamping force between the housing 3 and the mounting part 1.

[0027] When using, combine Figures 1-4 When the filter element 2 needs to be disassembled, first insert the filter element 2 directly into the inside of the housing 3, then align the housing 3 with the snap-fit ​​groove 13 on the mounting part 1, and screw it directly into the wedge groove 14. At this time, the sealing protrusion 32 on the top of the housing 3 and the sealing ring 12 cooperate and fit tightly together, thus completing the installation effect of the housing 3. At this time, the top of the limiting plate on the top of the filter element 2 is pressed against the sealing ring 12 at the bottom of the mounting part 1, thus completing the full sealing and fixing effect.

[0028] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
