And the hand wheel is provided with a bolt, a pin hole or other locking parts (the locking parts are common angle fixing parts in the prior art, the installation mode and the connection mode between the locking parts and the hand wheel are the existing mature technologies, and the details are not explained) for fixing the angle of the partition plate 3. In addition, the angle of the partition board 3 adjusted by the hand wheel is always 180 degrees, namely, the partition board 3 is always in the vertical position, and the engine can be ensured to always only pass through the F cavity when air is exhausted.

Equal fixedly connected with cavity filter core 4 on two relative lateral walls of baffle 3, the embedded spring 5 that is equipped with of cavity filter core 4, spring 5 set up and keeping away from 3 positions departments of baffle, and circular chamber 6 has been seted up to the lateral wall of base 1, and it should be explained that circular chamber 6 sets up in E chamber one side. A detachable sealing plate with good air tightness is arranged on part of the side wall of the base 1 near the circular groove 2 so as to conveniently replace the hollow filter element 4 in the filter tank 6.
