Simultaneously, the heating element transfers heat to the entire filter plate, heating the lubricating oil at the top.

This causes the movable rod to slide upward, and with the cooperation of the connecting rod, the two filter plates move upward. Simultaneously, the second and first compression springs are stretched. When the cam disengages from the ball, the force on the ball disappears. Under the restoring force of the second and first compression springs, the filter plates can move downward. This process is repeated, causing the filter plates to vibrate up and down. This prevents lubricating oil from sticking to the mesh of the filter plates, thus avoiding clogging.
