After a certain amount of lubricating oil is injected into the upper cavity 107, the electromagnetic switch valve 105 is closed through the controller, and the air source device 104 is opened. The air source device 104 inflates the inflation cavity 110 through the air outlet, the linkage piston 103 moves downwards under the action of air pressure, and the lubricating oil in the upper cavity 107 is squeezed into the lower cavity 108 from the composite filter element.
