Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example 1: as shown in fig. 1, the utility model relates to a ventilation passageway with automatic water conservancy diversion function, including main entrance 1, be equipped with outside bellied cushion chamber 2 on main entrance 1's the outer wall, just be connected with a passageway 3 on the cushion chamber 2, just one side that cushion chamber 2 and main entrance 1 contacted is equipped with air-out plate 4, be equipped with the exhaust vent 5 of a plurality of bars on the air-out plate 4, the both sides of the air-out end of exhaust vent 5 are equipped with the aviation baffle 6 of interior splayed.

The main channel 1 is provided with a guide plate 7 at the outer end of the air outlet plate 4. The air deflector 6 with the shape of the inner splayed shape plays a role in preventing gas backflow and avoiding the phenomenon of smoke mixing, the guide plate 7 is arranged at the outer end of the air outlet plate 4 of the main channel 1, the air in the main channel 1 is guided, the main channel 1 is prevented from entering the air outlet plate 4, and the functions of guiding the air and preventing the smoke mixing are achieved.
