Sequence of mechanical actions of the whole device:

when the device works, engine oil firstly enters the outlet 79 from the working oil cavity 14, then the pump motor 84 is started to drive the pump motor rotating shaft 83 to rotate anticlockwise, the pump motor rotating shaft 83 drives the pump inlet block 80 to rotate, the rotation of the pump inlet block 80 drives the pressure pump inlet plate 74 to rotate around the pump motor rotating shaft 83, when the pressure pump inlet plate 74 contacts the inner wall of the pressure pump inlet cavity 76, the pressure pump inlet plate is pushed to the axial center position of the pump motor rotating shaft 83 in the pump inlet plate sliding groove 75, then the engine oil is always attached to the inner wall of the pressure pump inlet cavity 76 under the action of the spring 78 when the engine oil continues to rotate, and the engine oil entering the pressure pump inlet cavity 76 rotates after being compressed to enter the pump outlet 82 and then is pushed to the filter inlet 44.

After entering the filtering inlet 44, the oil enters the upper filtering box 42, then the main motor 47 is started to drive the main motor shaft 48 and the buckling block 49 to rotate, then the electromagnet 50 is electrified to attract magnetic impurities in the oil to be adsorbed on the electromagnet 50, and the filtering screen frame 38 and the sleeve 56 are attracted to move downwards, so that the buckling protrusion 64 is inserted into the buckling groove 57, the rotation of the buckling groove 57 drives the buckling protrusion 64 to rotate, the sleeve 56 and the filtering screen frame 38 are driven to integrally rotate, and the oil enters the filtering outlet 55 through the filtering of the filtering screen 39 in the filtering cavity 61 and then enters the filtering outlet 52 and then enters other parts of the automobile.

After the internal circulation of the automobile is completed, the engine oil returns to the working oil cavity 14 through the oil return pipe 17, then impurities with larger mass are precipitated into the lower oil port 29 of the first layer, the second-layer oil cavity 25 and the third-layer oil cavity 21 at the bottom of the lower oil port, flow speed is reduced when the impurities flow in the second-layer oil cavity 25 and pass through the speed reducing cavity 24, then the impurities enter the third-layer oil cavity 21 and are precipitated into the precipitation cavity 23, and precipitation is prevented from entering the engine oil circulation again.

When the engine oil in the engine oil tank 12 needs to be replaced and the filter 30 needs to be cleaned, the push block 18 and the auxiliary push rod 73 are inserted into the slider threaded cavity 71 and screwed, and the push block 18 is pushed, so that the upper door plate 28 and the lower door plate 28 block a layer of lower oil port 29, the engine oil in the working oil cavity 14 at the upper end of the upper door plate and the engine oil in the second-layer oil cavity 25 are divided into two parts, then the hole-blocking screw 26 is screwed down from the oil-changing screw hole 27, the waste engine oil in the third-layer oil cavity 21 flows down from the oil-changing screw hole 27, then the sedimentation cavity 23 is taken down to take the sediment above the sedimentation cavity down for cleaning, then the hole-blocking screw 26 is screwed in the oil-changing screw hole 27 again, the ice crystal sedimentation plate 22 is installed again, when cleaning the filter 30, the upper filter box 42 is screwed down on the thread plate 53, and then the sleeve 56 is slid down from the rotating rod chamber 41 in its entirety to be removed and replaced, and the upper filter box 42 is again fixed on the upper end of the lower filter box 51 by rotation on the thread surface 60.
