[0038] When the device is used, the oil flows into the shell 1 through the oil inlet. Under the action of pressure, the oil passes through the filter paper 5, which can effectively intercept the impurity particles with small diameters and prevent them from entering the engine. When the oil passes through the filter paper 5, the impurity particles are adsorbed and intercepted on the surface of the filter paper 5. Due to the large surface area and special fiber structure of the filter paper 5, not only can the impurities be blocked on the surface by physical interception, but also some small particles in the oil can be adsorbed by the adsorption properties of the surface, thereby improving the cleanliness of the oil. The clean oil then enters the filter core 4 inside for further filtration, and the filter core 4 can remove impurities of different particle sizes to make the oil meet higher cleaning standards, thereby improving the precision and effect of filtration and providing better lubrication for the engine to ensure normal operation and prolong the service life of the engine. When it is necessary to replace the filter core 4 and filter paper 5 inside the shell 1, the handle 12 is pressed to make the clamping block 13 slide out of the clamping groove inside the mounting sleeve 7. At the same time, the first spring 14 is extruded by the sliding block 10 during the pressing of the handle 12. The sliding block 10 plays a role of connection and force transmission, and transmits the operating force of the handle 12 to the first spring 14 to make it elastically deform to provide power support for subsequent operation. Then, the handle 12 is rotated by 90 degrees to drive the clamping block 13 to rotate. The handle 12 is rotated to change the position of the clamping block 13 and achieve the unlocking of the clamping block 13 and the clamping groove of the mounting sleeve 7. During the rotation of the clamping block 13, the cooperation state between the clamping block 13 and the mounting sleeve 7 changes from the clamping state to the separation state. At this time, the clamping block 13 is pulled out of the mounting sleeve 7 by the rebound force of the first spring 14 to release the fixing effect. The rebound force of the first spring 14 pushes the connecting column 11 and the clamping block 13 to reset, ensuring that the clamping block 13 smoothly separates from the mounting sleeve 7, so that the connection between the end cover 2 and the shell 1 is released, ensuring the smooth operation of the disassembly. During the rotation of the connecting column 11, the cooperation between the limiting sleeve 15 and the limiting block 16 can limit and guide the rotating position of the connecting column 11. The limiting sleeve 15 provides a sliding track for the limiting block 16, and the limiting block 16 slides in the limiting sleeve 15. They work together to prevent the connecting column 11 from rotating excessively or deviating, ensuring that the connecting column 11 rotates accurately within the specified range and ensuring the stability and safety of the operation. At this time, the end cover 2 can be pulled upward to open the end cover 2 and replace the filter core 4 and filter paper 5 inside the shell 1, ensuring that the oil cleaner can continuously and effectively provide clean oil for the engine.
[0039] Reference Figure 5The sealing assembly comprises a sealing ring 17 which is slidably connected to the inner wall of the end cover 2 to effectively prevent oil leakage and ensure the oil to flow in the filter according to the predetermined path. The end cover 2 is fixedly connected with a mounting seat 18 which provides a stable mounting base for other components of the sealing assembly. The mounting seat 18 is fixedly connected with a fixing rod 22 which serves as a positioning and guiding component to provide a track for the movement of a sliding block 23 and a connecting block 20. The mounting seat 18 is fixedly connected with a mounting shell 19 which provides a containing space for a second spring 21, the connecting block 20 and a third spring 24. One end of the fixing rod 22 is fixedly connected to the side wall of the mounting shell 19 to further enhance the structural stability between the mounting seat 18 and the mounting shell 19. The mounting shell 19 is fixedly connected with the second spring 21, and one end of the second spring 21 is fixedly connected with the connecting block 20. The second spring 21 serves to provide an upward elastic force for the connecting block 20. The connecting block 20 is fixedly connected to the bottom of the sealing ring 17 and serves as a link between the second spring 21 and the sealing ring 17. The connecting block 20 transmits the elastic force of the second spring 21 to the sealing ring 17 to adjust the position and apply pressure to the sealing ring 17, thereby ensuring the sealing function of the sealing ring 17. The fixing rod 22 is slidably connected with the sliding block 23 which can change the relative position between the sliding block 23 and the sealing ring 17 by sliding on the fixing rod 22. In this way, the sealing state of the sealing ring 17 can be further adjusted and optimized to enhance the sealing effect. The sliding block 23 is rotatably connected with a rotating bar 25 which is rotatably connected to the bottom of the sealing ring 17. The fixing rod 22 is sleeved with the third spring 24 which is fixedly connected to the side wall of the sliding block 23 at one end and to the mounting shell 19 at the other end. The third spring 24 provides a restoring force for the sliding block 23 to ensure that the sealing assembly can maintain a stable working state under different working conditions and always maintain good sealing performance during multiple uses.
[0040] In the process of engine operation, vibration will be generated, at this time, the vibration will be transmitted to the sealing ring 17, when the vibration is transmitted to the sealing ring 17, the rotating bar 25 is pushed to rotate by the sealing ring 17. The rotating bar 25 plays a role of bridge of transmitting vibration and force here, converts the vibration received by the sealing ring 17 into its own rotating action, so that the vibration can be effectively transmitted and converted inside the sealing assembly. After the rotating bar 25 rotates, it will push the sliding block 23 to slide, the sliding block 23 slides on the fixed rod 22, so that the linkage is generated inside the sealing assembly, which provides conditions for the dynamic adjustment of the entire sealing structure, so that the sealing assembly can make corresponding adjustment according to different vibration conditions to maintain good sealing performance. At the same time of sliding of the sliding block 23, the third spring 24 is extruded and shrunk. The third spring 24 plays a role of buffer and adjustment here, when the sliding block 23 slides, the third spring 24 is extruded and shrunk, stores the energy generated by the vibration, and also provides elastic restoring force for subsequent reset. At the same time, the connecting block 20 will also slide, the sliding of the connecting block 20 can transmit the influence of vibration to the second spring 21, and also drive the sealing ring 17 to adjust the position within a certain range, so that the sealing ring 17 can adaptively adjust according to different vibration conditions and deformation of engine parts. When the connecting block 20 slides, the second spring 21 is extruded and shrunk, similar to the third spring 24, when it is extruded and shrunk by the connecting block 20, it stores elastic potential energy, after the vibration disappears or decreases, through its own elastic restoring force, the connecting block 20 and the sealing ring 17 can be restored to the original position or state. Through the elastic force between the springs, the sealing ring 17 always maintains close contact with the engine, the elastic force of the spring plays a key role in adjustment and maintenance, can automatically adjust the degree of deformation according to the size of the vibration, and then adjust the position and state of the sealing ring 17, so that the sealing ring 17 closely contacts the related parts of the engine, prevents the sealing ring 17 from loosening due to vibration during operation, prevents oil leakage, through the cooperation of the spring and the sealing assembly, the oil leakage can be effectively avoided, and stable and reliable lubrication of the engine under various working conditions can be ensured.
[0041] Working principle: when using the device, the oil flows into the inside of the shell 1 through the oil inlet, under the action of pressure, the oil passes through the filter paper 5, and the filter paper 5 intercepts the impurity particles with smaller diameter, when the oil passes through the filter paper 5, the impurity particles are adsorbed and intercepted on the surface of the filter paper 5, and the clean oil passes through the filter paper 5 into the filter core 4 inside to further filter, so as to improve the precision and effect of filtering, when the filter core 4 and the filter paper 5 inside the shell 1 need to be replaced, the handle 12 is pressed to make the clamping block 13 slide out of the clamping groove inside the mounting sleeve 7, at the same time, the first spring 14 is extruded through the sliding block 10, then the handle 12 is rotated by 90 degrees, so as to drive the clamping block 13 to rotate, at this time, the clamping block 13 is pulled out of the inside of the mounting sleeve 7 through the rebound force of the first spring 14, so as to release the fixing effect, in the process of rotating the connecting column 11, the rotating position of the connecting column 11 can be limited and guided through the cooperation between the limiting sleeve 15 and the limiting block 16, at this time, the end cover 2 can be pulled upwards to open the end cover 2 to replace the filter core 4 and the filter paper 5 inside the shell 1, during the operation of the engine, the vibration will be transmitted to the sealing ring 17, the rotating strip 25 is pushed to rotate through the sealing ring 17, so as to push the sliding block 23 to slide and extrude and shrink the third spring 24, at the same time, the connecting block 20 also slides to extrude and shrink the second spring 21, through the elastic force between the springs, the sealing ring 17 can always be kept in close contact with the engine, so as to prevent the sealing ring 17 from loosening due to vibration during operation, and cause oil leakage.
[0042] The remaining part of the embodiment is the same as that of example one, the features not explained in the embodiment are explained by using the explanation of example one, and details are not repeated here.
