FIELD OF THE INVENTION
The present invention relates to a ventilation device for a building which circulates air freely in the building.
BACKGROUND OF THE INVENTION
A conventional ventilation structure for a building contains an exhaust fan for cooling a temperature of an interior of the building. However, the exhaust fan is driven to operate by a power, thus enhancing energy consumption and electricity cost. Furthermore, the exhaust fan cannot discharge rains out of the building in case the rains drop into the building.
The roof cannot transmit lights into the building from external environment.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary aspect of the present invention is to provide a ventilation device for a building which circulates air freely in the building.
Further aspect of the present invention is to provide a ventilation device for a building which avoids rains dropping into the building to obtain waterproof effect.
Another aspect of the present invention is to provide a ventilation device for a building which dissipate heat out of the building easily.

In addition, the rainwaters do not drop into the building by ways of the multiple second stop sheets 304, the second tilted guide plate 306, the first auxiliary guide plate 307, and the third tilted guide plate 308 of the second ventilation system 300. Preferably, even though the rainwaters drop into the multiple second discharge orifices 305, they are stopped and guided by the first auxiliary guide plate 307 to discharge out of the third drain hole 309. In addition, external lights emit into the building via the first light transmission plate 303.
