[0101] The lower end of the elastic metal sheet 83 is deformed and pressed against the inner wall of the wine storage tank body 1 , and the upper end of the elastic metal sheet 83 is bent toward the middle of the wine storage tank body 1 .

[0102] When the filter assembly 8 needs to be removed, open the cover 2, grasp the upper ends of the elastic metal sheets 83 on both sides from the upper end of the wine storage tank body 1, and squeeze the upper ends of the elastic metal sheets 83 toward the middle of the wine storage tank body 1, so that the elastic metal sheets 83 are elastically deformed, reducing the force against the inner wall of the wine storage tank body 1, and then lift the filter assembly 8 to remove the filter assembly 8 from the upper end of the wine storage tank body 1.

[0103] Working principle:

By observing whether the sealed drain valve body 4 is leaking wine, it is possible to intuitively judge whether the seal here is aging, which is convenient for timely replacement.
