[0043] The blocking assembly is horizontally arranged on the upper end of the switching cylinder 25 by means of screws. The blocking assembly comprises a blocking plate 35. The upper end of the switching cylinder 25 is movably arranged through the center of the detachable cover plate 24. The blocking plate 35 is horizontally sleeved on the upper end of the switching cylinder 25 by means of screws.

[0044] When the vacuum system inlet pipe 10 is connected to the space to be vacuumized, the vacuum system suction pipe 2 is connected to the vacuumizing device, and air is sucked from above. When the sucked gas contains moisture, the water vapor gas in the vacuum system inlet pipe 10 enters the switching cylinder 25, the body of the switching cylinder 25 enters the arc-shaped guide groove 36 from the butt joint hole and the butt joint groove 37, and then is blown to the arc-shaped side of the detachable cover plate 24 under the guide of the arc-shaped guide groove 36.

With the lowering of the switching cylinder 25, the cantilever plate 33 drives the synchronous rod 34 to control the annular blocking plate 31 to descend and expose the air hole 30, so that the upper end of the filtering cavity 22 is connected with the outside.

When the sealing plate 35 is lifted, the sealing seat cooperates with the annular blocking plate 31 to make the filtering cavity 22 in a self-sealing state, thereby preventing the pollution of the filtering plate 23 when the moisture-containing gas is trapped.

[0047] After the filtering plate 23 is used for a certain period of time, the sealing plate 35 and the detachable cover plate 24 can be sequentially removed and maintained and replaced by bolts.
