The first position-limiting portion 32 and the second position-limiting portion 33 have relative movement in the vertical direction to switch between a fixed state and a movable state of the filter unit 5, that is, the first position-limiting portion 32 and the second position-limiting portion 33 perform relative movement in the vertical direction to form a clamping action in the vertical direction on a portion of the filter unit 5 located between the first position-limiting portion 32 and the second position-limiting portion 33 or release the clamping action.

Further, the first position-limiting portion 32 is fixed to the isolation portion 31, and may be detachably connected, such as screwed bolt fixed, or may be integrally formed with the isolation portion 31, and is not limited specifically. The second stopper 33 is movably disposed with respect to the isolation portion 31 and is movable in a vertical direction of the isolation portion 31. Specifically, the second position-limiting portion 33 is movable toward or away from the first position-limiting portion 32 to switch the position-limiting state and the releasing state of the second position-limiting structure 3. For the second position-limiting part 33 moving in the vertical direction of the isolation part 31, the second position-limiting part 33 may be sleeved on the isolation part 31, and slide on the isolation part 31, and fix the second position-limiting part 33 through a position-limiting structure; the second position-limiting portion 33 may be integrally formed with the isolation portion 31, and the second position-limiting portion 33 may be plastically deformed in the vertical direction.
