As shown in Figure 3a and Figure 3b shows, one-way exhaust pipe 22 includes outer tube 221, multiple inner tubes 222, multiple active blades 223.
The internal diameter of outer tube 221 is more bigger than the outer diameter of inner tube 222, or both equivalent.Inner tube 222 is arranged in outer tube 221.It is two neighboring
It is spaced apart between inner tube 222, form an interval region 220.Active blade 223 is arranged in interval region 220.It is living
The appearance and size of dynamic catch 223 is more than the internal diameter of inner tube 222, and less than the internal diameter of outer tube 221, therefore it can be in interval region
It is movable in 220.
Two adjacent end faces of two neighboring inner tube 222 have a different configuration, or it can be said that each inner tube 222
It is even surface that two end faces, which have different constructions, one of end face, and groove is provided on another end face, is formed uneven
Face.
For shown in Fig. 3 a and Fig. 3 b, the end face 222a of left side inner tube 222 is even surface, the end face of the right inner tube 222
