[0027] Please see Figure 3In order to quickly filter the oil in the filter ring cylinder 4 multiple times, the filter mechanism 6 includes a filter ring cavity 61. The outer wall of the filter ring cavity 61 is embedded and connected to the inner wall of the filter ring cylinder 4. An oil drain hole 62 is provided at the top of the outer wall of the filter ring cavity 61. A filter screen 63 is provided on the inner wall of the oil drain hole 62. A filter ring 64 is fixedly connected to the inner wall of the filter ring cavity 61. Filter holes 65 are opened around the outer periphery of the filter ring 64. A filter ring 66 is fixedly connected to the bottom of the inner wall of the filter ring cavity 61. An oil inlet hole 67 is opened on the bottom wall of the filter ring cavity 61. An oil drain hole 62 is opened at the top of the outer wall of the filter ring cavity 61. The inner wall of the oil drain hole 62 is fixedly connected to the outer wall of the filter screen 63. The upper end of the oil inlet hole 67 penetrates the top wall of the filter ring cavity 61 and extends to the bottom of the filter ring cylinder 4.

[0028] To achieve efficient and multiple filtration of the engine oil within the filter ring cylinder 4, the filter mechanism 6 includes a filter ring cavity 61. The outer wall of this filter ring cavity 61 is tightly embedded and connected to the inner wall of the filter ring cylinder 4, ensuring structural stability. At the top of the outer wall of the filter ring cavity 61, oil drain holes 62 are provided. Filter screens 63 are installed on the inner walls of these oil drain holes 62 to ensure the quality of the discharged oil. A filter ring 64 is fixed to the inner wall of the filter ring cavity 61.

The liquid discharge mechanism 5 includes a sealing ring 51, whose inner wall is rotatably connected to the outer wall of the filter ring cylinder 4, ensuring sealing and rotational flexibility. A liquid storage chamber 52 is set on the inner wall of the sealing ring 51 for temporarily storing the filtered liquid to be discharged. A discharge pipe 53 is set on one side of the sealing ring 51, and a solenoid valve 54 is fixed to the outer wall of the discharge pipe 53. The solenoid valve 54 controls the opening and closing of the discharge pipe 53, thereby achieving orderly liquid discharge. Furthermore, the... The outer wall of mounting hole 2 is connected to the inner wall of mounting ring 1 through the hole, which ensures the stability of the installation. The inner wall of fixing ring 3 is movably connected to the inner wall of mounting ring 1. This setting allows fixing ring 3 to move within a certain range to adapt to different installation requirements. The inner wall of sealing ring 51 is embedded and connected to the outer wall of liquid storage chamber 52, so that liquid storage chamber 52 can be stably set in sealing ring 51, ensuring stable storage of oil in liquid storage chamber 52. One end of discharge pipe 53 is connected to one side of sealing ring 51, ensuring that oil can be smoothly discharged from liquid storage chamber 52 through discharge pipe 53.

[0030] To achieve efficient and multiple filtration of the engine oil within the filter ring cylinder 4, the filter mechanism 6 includes a filter ring cavity 61. The outer wall of this filter ring cavity 61 is tightly embedded and connected to the inner wall of the filter ring cylinder 4, ensuring structural stability. At the top of the outer wall of the filter ring cavity 61, oil drain holes 62 are provided. Filter screens 63 are installed on the inner walls of these drain holes 62 to ensure the quality of the discharged oil. A filter ring 64 is fixed to the inner wall of the filter ring cavity 61. Multiple filter holes 65 are evenly distributed around the outer periphery of this filter ring 64 to facilitate oil filtration. In addition, another filter ring 66 is fixedly connected to the bottom of the inner wall of the filter ring cavity 61 to further improve the filtration efficiency. An oil inlet hole 67 is provided on the bottom wall of the filter ring cavity 61.

Finally, an oil drain hole 62 is also provided on the top of the outer wall of the filter ring cavity 61. The inner wall of the oil drain hole 62 is firmly connected to the outer wall of the filter screen 63, ensuring that the filtered engine oil can be smoothly discharged.

The outer wall of filter ring 64 fits against the inner wall of filter ring cavity 61, and the outer wall of filter ring 66 fits against the inner wall of filter ring cavity 61. The size of filter holes 65 on the outer periphery of filter ring 64 is smaller than the size of filter holes 66 on the outer periphery of filter ring 66. During use, engine oil enters filter ring cavity 61 through oil inlet 67. After initial filtration by filter ring 66, the engine oil flows into filter ring 64, undergoes fine filtration through filter holes 65, and finally exits through filter screen 63 and drain through drain hole 62. When it is necessary to drain engine oil, solenoid valve 54 is opened, and engine oil is drained through reservoir 52 and drained through drain pipe 53. Simultaneously, the liquid outlet mechanism 5 is rotated, causing it to rotate on the outer wall of the filter ring cylinder 4. This position facilitates the discharge of engine oil. The multi-layer filtration mechanism 6 allows the engine oil to pass through multiple layers of filtration, preventing blockage by impurities of various sizes. Furthermore, when the filter screen 63 is removed, impurities are less likely to pass through the filter holes and fall into the engine oil, thus avoiding re-contamination.
