When filtering the water sample, the staff can pour the water sample into the stainless steel filter cup 3, and the air in the liquid storage bottle 6 can be extracted by driving the vacuum mechanism 9 through the suction pipe 7 connected to the exhaust parallel pipeline 8. Under the action of pressure, the water sample is filtered through the filter membrane on the filter mechanism 4 and then flows into the liquid storage bottle 6 through the first drainage pipe 5.

[0029] Furthermore, two groups of filtering mechanisms 4 are provided, and are symmetrically arranged at the two ends of the filtering bracket 1 in sequence, and one group of filtering mechanisms 4 includes: a filtering plate 41, on which a filtering membrane net 42 is provided, and the number of filtering membrane nets 42 is several, and the several filtering membrane nets 42 are uniformly arranged on the filtering plate 41 in sequence, and a sealing gasket ring 43 is provided on the outer side of the several filtering membrane nets 42.
