The vortex cavity 10 is arranged in the vortex box 1, is communicated with the air inlet combination 11, the air outlet combination 12 and the waste gas channel 13, and is used for containing gas entering through the air inlet combination 11 and enabling the gas to form at least one strong vortex in the vortex cavity 10. In the present embodiment, the vortex chamber 10 also serves as a working space, and when a worker works in the vortex chamber 10, waste gas is directly generated in the vortex chamber 10.

In this embodiment, the vortex chamber 10 is cylindrical, and in other embodiments, referring to fig. 5, the vortex chamber 10 is rectangular. It should be understood that the vortex chamber 10 can also be other regular or irregular shapes.
