FIELD OF THE INVENTION
The present invention relates to a ventilation structure for a building which dissipates the heat and drop the temperature of the interior of 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 structure for a building which dissipates the heat and drop the temperature of the interior of the building.
Further aspect of the present invention is to provide a ventilation structure for a building which avoids rains dropping into the building by using the at least one atop plate, the first beveled guide plate, and the second beveled guide plate.
Another aspect of the present invention is to provide a ventilation structure for a building which transmits lights into the building through the second light transmission plate of the short extension and the first light transmission plate of the first tilted section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIGS. 1 and 2, a ventilation stricture for a building according to a preferred embodiment of the present invention comprises: a cover 10 mounted on an exhaust orifice 30 of a flat roof 31, the cover 10 includes a short extension 11 and a long extension 13 arranged on two side of the cover 10 respectively, wherein the long extension 13 has a first tilted section 14, a second tilted section 15 below the first tilted section 14, a first light transmission plate 16 engaged on the first tilted section 14, a second light transmission plate 12 engaged on the short extension 11, a first beveled guide plate 20 extending from a top of the short extension 11 to the cover 10, a hooked plate 21 extending from a top of the first tilted section 14 of the long extension 13, an air outlet 32 defined between the beveled guide plate 20 and the hooked plate 21, at least one atop plate 24 arranged on the air outlet 32, a side plate 22 located below the beveled guide plate 20, a second beveled guide plate 23 connected with the side plate 22 and the second tilted section 15 of the long extension 13, and a drainage hole 25 defined between the second beveled guide plate 23 and the second tilted section 15.
Referring to FIGS. 2 and 3, when an external airflow flows through the short extension 11 or the long extension 13, air of the air outlet 32 is actuated by the external airflow so as to absorb a heat of the air in the exhaust orifice 30 of the flat roof 31, such that the heat is discharged out of the air outlet 32 via an air returning space 33 so as to dissipate the heat and drop a temperature of an interior of the building.
Preferably, rains are stopped dropping into the building by the at least one atop plate 24, the first beveled guide plate 20, and the second beveled guide plate 23. Even though the rains drop into the building rarely, they are discharge out of the drainage hole 25. Lights transmit into the building through the second light transmission plate 12 of the short extension 11 and the first light transmission plate 16 of the first tilted section 14.
As shown in FIGS. 4 and 5, in another embodiment, the cover 10 is mounted on a slanted roof 40 so as to obtain ventilation, rain protection, and light transmission.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
