After starting the filter, the oil extraction pipe sucks the oil liquid at the bottom of the barrel body 100 to the filter through the liquid extraction pipe 2 for filtration. The filtered oil liquid flows into the pipe cavity of the fixed pipe 1 through the oil discharge pipe and the second connecting pipe 4, and then flows back to the upper part of the barrel body 100. Therefore, when filtering with the liquid filtering auxiliary tool of this embodiment, there is no need to switch the oil liquid back and forth between two barrel bodies 100, the oil liquid can be cyclically filtered in one barrel body 100, and there is no need for manual switching of the oil extraction pipe and the oil discharge pipe between two oil barrels, reducing the labor cost.

[0036] Among them, to ensure the service life of the auxiliary tool for liquid filtration, both the fixed pipe 1 and the first connecting pipe 3 are metal pipes. The upper end of the first connecting pipe 3 passes through the pipe wall of the fixed pipe 1 and is connected to the liquid extraction pipe 2.

Specifically, the adapter 5 is of an L-shaped structure, and the sum of the length of the horizontal section of the adapter 5 and the diameter of the fixed pipe 1 is less than the diameter of the fixed pipe 1, so as to ensure that the upper end of the liquid extraction pipe 2 provided with the adapter 5 can be smoothly inserted into the fixed pipe 1.

To ensure that the liquid at the bottom of the barrel body 100 can smoothly flow into the liquid extraction pipe 2, a bevel 21 is provided at the lower end of the liquid extraction pipe 2. Specifically, the lowermost end of the bevel 21 abuts against the bottom wall of the barrel body 100, and there is a gap between the slope of the bevel 21 and the bottom wall of the barrel body 100.
