That is, at least a portion of the oil plug 200 may extend into the inner cavity 110 through the opening, and at least a portion of the oil plug 200 may also extend out of the filter cartridge 100 through the oil plug 200.

The oil outlet hole 220 is switchable between the first position and the second position with the movement of the oil plug 200.

In the first position, the oil inlet 210 is located in the interior cavity 110 and the oil outlet 220 is blocked off from the filter cartridge 100. In this case, the filter cartridge 100 is in a closed state, and the filter device can be normally used.

In the second position, the oil inlet 210 is located in the interior cavity 110 and the oil outlet 220 is located outside of the filter cartridge 100. In this case, the inner cavity 110 communicates with the outside atmosphere through the oil outlet hole 220, so that the oil in the inner cavity 110 can flow out through the oil inlet hole 210 and the oil outlet hole 220.

When the filtering device needs to be overhauled, the oil plug 200 is moved to the second position, the oil outlet hole 220 is exposed out of the filter cylinder 100, the pressure, the flow rate and the flow rate of oil discharged from the oil outlet hole 220 are observed, and when the pressure of the discharged oil is low and the flow rate is low, the oil inlet passage of the filtering device is successfully blocked, so that the filtering device can be overhauled; when the oil pressure that flows out is great and can't drain off, it indicates that filter equipment's oil feed passageway is not successfully blocked, needs to take other measures to overhaul filter equipment. And in the second position, the oil plug 200 is not completely separated from the filter cartridge 100, the oil plug 200 is still connected with the filter cartridge 100, and when the oil inlet passage of the filter device is found to be blocked, the oil plug 200 can be rapidly switched to the first position to ensure that the filter device does not continuously spray oil.
