Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Example 1
Referring to the attached drawing 1, the utility model discloses a suction filtration device for water microorganism sampling, which comprises a sealing cover 1, a suction filtration container 2, a filter membrane 3 and a vacuum pump 4; the sealing cover 1 is rotatably connected with the suction filtration container 2, two holes are formed in the sealing cover 1 in parallel, and a first protruding pipe installation structure 5 and a second protruding pipe installation structure 6 are respectively arranged on the two holes in a sealing manner; the first protruding pipe-mounted structure 5 is connected with the water outlet 8 of the filter membrane 3; the second protruding pipe installation structure 6 is connected with the vacuum pump 4 through a connecting hose 7, and a water inlet 9 of the filter membrane 3 is connected with a water source.
Preferably, the filter membrane 3 is a syringe-shaped microporous filter membrane.
Preferably, the first protruding tubular structure 5 is connected with the water outlet 8 of the filter membrane 3 through a hose.
Preferably, the inner diameter of the first protruding tubular structure 5 is just enough to enable the water outlet 8 of the filter membrane 3 to be inserted into the first protruding tubular structure 5.
Preferably, the second male tubular structure 6 has an outer diameter just sufficient to enable the connection hose 7 to be connected to the second male tubular structure 6.
Example 2
