[0030] During implementation, the disassembly plate 112 drives the positioning slot 4032 away from the surface of the positioning card 4031. At this time, the positioning card 4031 drives the arc-shaped card 402 away from the inside of the arc-shaped slot 4033, thereby removing the disassembly plate 112 from the surface of the oil filter body 1. Subsequently, the user pulls the filter paper body 101 to make the filter paper body 101 slide on the surface of the guide groove 401. The filter paper body 101 is guided by the guide groove 401, thereby pulling the filter paper body 101 out from the inside of the oil filter body 1, and cleaning the surface of the filter paper body 101 to achieve the function of cleaning the oil filter.

[0031] Working principle: When in use, first place the oil filter body 1 on one side of the motor. At this time, the user rotates the oil filter body 1, so that the oil filter body 1 drives the fixing screw hole 105 to rotate, and the oil filter body 1 is installed at the specified position of the motor under the thread cooperation between the fixing screw hole 105 and the mounting screw tube 103. At this time, one end of the oil inlet pipe 107 is inserted into the inside of the connecting plate 102, and the sealing ring 2032 and the clamping pad 2033 are driven to move under the joint action of the telescopic spring 201 and the spring body 2031 inside the sealing ring 202, so that The sealing ring 2032 drives the clamping pad 2033 to move to fit the surface of the oil inlet pipe 107. Under the joint action of the sealing ring 2032 and the clamping pad 2033, the oil inlet pipe 107 can be clamped on the surface of the connecting plate 102, thereby avoiding the oil inlet pipe 107 from being deflected when the oil is being fed, so as to realize the function of accurate oil feeding of the oil filter, so that when the oil filter is in use, the oil can accurately enter the interior of the oil filter body 1 through the oil inlet pipe 107 and the oil inlet hole 108, thereby avoiding the phenomenon of oil leakage during the use of the oil filter.

[0032] Subsequently, when the mounting screw 103 is installed inside the fixing screw hole 105, at this time, the mounting screw 103 drives the sealing frame 304 to move to contact the surface of the fixing screw hole 105, and the sealing airbag 303 inside the sealing frame 304 drives the sealing plate 302 and the sealing gasket 301 to move, so that the sealing plate 302 drives the sealing gasket 301 to move to fit the surfaces of the mounting screw 103 and the fixing screw hole 105, and the mounting screw 103 and the fixing screw hole 105 are pressed together by the sealing plate 302 and the sealing gasket 301. The fixed screw holes 105 are sealed to prevent the oil from leaking out from between the mounting screw tube 103 and the fixing screw hole 105 due to the mounting screw tube 103 loosening from the inside of the fixing screw hole 105, so as to realize the function of the oil filter to seal between the mounting screw tube 103 and the fixing screw hole 105, so that the oil filter is not easy to loosen after installation, and the air tightness between the mounting screw tube 103 and the fixing screw hole 105 is better when the oil filter is in use, so that the overall stability of the oil filter is higher.

[0033] Subsequently, the engine oil enters the interior of the oil filter body 1 through the oil inlet pipe 107 and the oil inlet hole 108, and the engine oil is checked by the check valve 104. At this time, the engine oil enters the interior of the oil filter body 1 through the gap between the oil inlet hole 108 and the check valve 104. At this time, the engine oil is filtered under the action of the oil filter body 1, and impurities in the engine oil remain on the surface of the filter paper body 101. Subsequently, when the surface of the oil filter body 1 is blocked after long-term use, the engine oil will jump through the filter paper body 101 to open the overflow valve 111 and directly enter the interior of the motor. The impurities in the unfiltered engine oil will damage the motor, and the engine oil is filtered under the action of the mesh body 109 and the filter mesh 106.

[0034] Subsequently, after the filter paper body 101 has been used for a long time, the surface is prone to blockage. The user pulls down the disassembly plate 112 to move the disassembly plate 112 to the side away from the oil filter body 1, and the disassembly plate 112 drives the positioning groove 4032 away from the surface of the positioning clamp 4031. At this time, the positioning clamp 4031 drives the arc-shaped clamp 402 away from the inside of the arc-shaped groove 4033, thereby removing the disassembly plate 112 from the surface of the oil filter body 1. Subsequently, the user pulls the filter paper body 101 to make the filter paper body 101 The guide slot 401 slides on the surface of the guide slot 401, and the filter paper body 101 is guided under the action of the guide slot 401, so that the filter paper body 101 is pulled out from the interior of the oil filter body 1, and the surface of the filter paper body 101 is cleaned to realize the function of facilitating the cleaning of the oil filter, so that the filter paper body 101 can be cleaned regularly when the oil filter is used, so that the convenience of cleaning the surface of the filter paper body 101 of the oil filter is greatly improved, and it is more practical, and finally the use of the oil filter is completed.
