Specific embodiment one:

[0028] See also Figure 1-5 As shown, the utility model is an oil circulation cleaning device, comprising a reflux flusher 1, an oil pump 2, a reflux oil storage filter tank 3 and a workbench 4. The oil pump 2 and the reflux oil storage filter tank 3 are respectively installed on the workbench 4. The oil pump 2 and the reflux oil storage filter tank 3 are connected through a first oil pipe 5. The oil pump 2 and the reflux flusher 1 are connected through a second oil pipe 6. The reflux flusher 1 and the reflux oil storage filter tank 3 are connected through a third oil pipe 7. The reflux flusher 1 specifically includes a flushing pipe 11 and a receiving cup 12. The flushing pipe 11 passes through the receiving cup 12, and a plurality of sealing rings 13 are arranged between the flushing pipe 11 and the receiving cup 12. The upper end of the flushing pipe 11 is fixedly connected to a ball head 14 with a cavity. A plurality of flushing holes 15 are provided on the top of the ball head 14. A semicircular arc nozzle 16 is provided in the middle of the ball head 14. An oil pipe joint 17 is fixedly passed through the bottom of the receiving cup 12. The lower end of the flushing pipe 11 is connected to one end of the second oil pipe 6. The other end of the second oil pipe 6 is connected to the oil outlet of the oil pump 2. The oil pipe joint 17 is connected to the third oil pipe 7. A gripping handle 18 is installed on the outer wall of the flushing pipe 11 and below the receiving cup 12.

[0029] When changing the engine oil of a vehicle, release the engine oil in the reflux oil storage filter tank 3, and place the reflux oil storage filter tank 3 on the workbench 4. Start the oil pump 2, and the oil pump 2 pressurizes the discharged engine oil to the reflux flusher 1. The ball head 14 of the reflux flusher 1 extends into the oil box from the oil drain hole, and a part of the high-pressure reflux oil is output from a plurality of flushing holes 15 to flush the upper wall of the oil box, and the other part of the reflux oil is output from the semicircular arc nozzle 16 to flush the side wall and bottom wall of the oil box. By reciprocating up and down movement of the reflux flusher 1, the inner wall of the oil box is cleaned of oil sludge, thereby improving the completeness of the engine oil replacement.

[0030] The reflux oil storage filter tank 3 includes an oil storage tank 31, an upper cover 32 and a filter 33. The oil storage tank 31 has an open barrel 311. A cylindrical tube 312 is fixed through the bottom wall of the barrel 311, and the upper end of the cylindrical tube 312 is placed above the upper end surface of the barrel 311, and the lower end of the cylindrical tube 312 is placed below the bottom surface of the barrel 311. An external thread 313 threadedly connected to the filter 33 is provided on the outer wall of the lower end of the cylindrical tube 312. Four oil holes 314 are provided on the bottom surface of the barrel 311. Two radially arranged lap plates 315 are fixed to the outer wall of the upper end of the barrel 311 in an axially symmetrical manner. A first handle 316 is fixed on the upper surface of the lap plate 315. The upper end of the cylindrical tube 312 is connected to one end of the first oil pipe 5, and the other end of the first oil pipe 5 is connected to the oil inlet end of the oil pump 2.
