It has the function of gathering wind by arranging reducers at both ends of the traditional straight ventilation pipe, increasing the natural ventilation volume, and adopting one or more sets of ventilation duct facilities arranged in the wall to prevent and control indoor air pollution, which can not only satisfy the masses, but also save costs and is easy to construct. It is particularly suitable for the design and renovation of green and environmentally friendly toilets in areas with abundant wind in all seasons and the prevention and control of air pollution in the decoration of new houses.

[0005] In response to the above problems, although the solution given by the existing patent has the function of gathering wind and increasing natural ventilation by setting reducers at both ends of the traditional straight air duct, it uses local air intake and then removes the indoor hot and humid air and winter fog, which makes the local air intake area at the low part of the wall small and the air suction efficiency low.
