Embodiment 1:

Fig. 1 schematically illustrates the structure diagram of the filter of the utility model embodiment, as shown in Figure 1, the mistake Filter includes:

Filter, the filter include cavity 35, lid 31 and filter medium 34, and the cavity 35 has import 32 and goes out Mouth 33, the filter medium 34 are arranged in the cavity 35, and the lid 31 has through-hole；Liquid passes sequentially through the import 32, filter medium 34 and outlet 33；

First part, the first part are arranged in the through hole, and outside the cavity；First part's packet Pipeline 11 and rotating member 21 are included, the pipeline 11 has the first import 12, the second inlet and outlet 13, and the rotating member 21 has There is a through-hole 22, and be arranged in the pipeline 11, the first import 12 of the pipeline 11 and goes out when the rotating member 21 rotation It selectively communicates with or is isolated between mouth 13, the pipeline is fixed on the through-hole 22 in the second entrance, is such as connected through a screw thread And it seals；

The through hole of the lid 31 is arranged in second part, the second part, and in the cavity 35；Described Two parts include container 43, buoyancy piece 42, connector 41 and converting unit 44, and the buoyancy piece 42 and the setting of connector 41 exist In the container 43；The container 43 have through-hole 45, the connector 41 pass through the lid 31 through-hole and with the rotation Part 21 connects, and 43 inside of container is connected to the through-hole of the rotating member 21；The converting unit 44 is by the buoyancy piece 42 Up and down motion be converted to rotation, the rotating member 21 is rotated with the buoyancy piece 42, the buoyancy piece 42 and the connection Part 41 has the relative motion of vertical direction.

In order to which the up and down motion of the buoyancy piece is converted to rotation, so that buoyancy piece spiral or decline, Yi Jilian The rotation in situ (no to move up and down) of fitting, further, the converting unit includes:

Moving member, the movement are suitable for moving on guide rail；The moving member is arranged at the buoyancy piece (container inner wall) On；

Guide rail, the guide rail tilt upward, and are arranged on container inner wall (buoyancy piece).

In order to enable buoyancy piece and connector only have the relative motion of up and down direction, further, the buoyancy piece covers On the connector, on the section of the central axis perpendicular to the connector, the connector is in non-circular, such as four sides Shape, hexagon etc..

In order to carry out the sealing effect of pipeline, the rotation angle of the connector is no more than 90 degree, such as 90 degree.

The course of work of the filter of the utility model embodiment:

(A1) gas source provides first gas, passes through the logical of rotating member by the first gas that first import enters pipeline Hole (at this point, the angle between the central axis of the through-hole of rotating member and the central axis of pipeline is 0 degree), later from the outlet of pipeline It is discharged, the pressure reduction in container；

(A2) second gas in container enters in the through-hole of the rotating member after being upward through the through-hole of lid, and by first Gas is taken away；

(A3) the liquid level driving buoyancy piece risen in container moves up, and the conversion that moves upwards of buoyancy piece is positive by converting unit To rotation；

(A4) connector is rotated in the forward direction with the buoyancy piece, and then the rotating member is driven to rotate in the forward direction, such as rotation 90 It spends, is blocked inside the pipeline, if the angle between the central axis of rotating member through-hole and the central axis of pipeline is 90 degree, no There is first gas to pass through the through-hole on rotating member again；

(A5) gradually gathering with gas in container, the pressure in container rise, and the liquid level decline in the container is floated Power part moves down, and moving downward for buoyancy piece is converted to reverse rotation by converting unit；
