[0017] In this embodiment, the waste oil channel B8 is directly connected with the waste oil outlet 5, the waste oil channel B8 extends to the inside of the piston cylinder 12, the waste oil channel B8 is connected with the inside of the piston cylinder 12, one end of the advance and retreat screw rod 2 is installed at one end of the motor 1 close to the inside of the piston cylinder 12, the waste oil channel A9 is connected with the inside of the waste oil inlet nozzle 11, the waste oil inlet 10 is connected with the inside of the waste oil inlet nozzle 11, and the outside of the piston main body 13 is closely attached to the inside of the piston cylinder 12.

[0018] Specifically, first, the motor 1 is started to drive the advance and retreat screw rod 2 to rotate, so that the piston main body 13 moves linearly in the cavity of the piston cylinder 12. Since the outside of the piston main body 13 is closely attached to the cavity of the piston cylinder 12, and the thin rod at one end of the piston main body 13 is closely attached to the inner cavity of the waste oil inlet nozzle 11, when the piston main body 13 moves towards the side close to the motor 1, a vacuum is formed in the cavity of the piston cylinder 12 away from the piston main body 13. The piston main body 13 moves to the limit position in the cavity of the piston cylinder 12. At this time, the waste oil channel A9 is connected with the waste oil inlet 10, and under the action of air pressure, the waste lubricating oil accumulated near the waste oil inlet nozzle 11 is pressed into the cavity of the piston cylinder 12 through the waste oil inlet 10 and the waste oil inlet nozzle 11.

The thin rod at one end of the piston main body 13 is inserted into the inner cavity of the waste oil inlet nozzle 11, so that the waste oil channel A9 is quickly sealed. The waste lubricating oil in the cavity of the piston cylinder 12 is squeezed out by the piston main body 13, and flows to the waste oil outlet 5 through the waste oil channel B8, and the waste lubricating oil pushes open the one-way valve 6 and is discharged from the waste oil outlet 5, forming a first waste lubricating oil suction and discharge.
