Ventilation roof

Abstract

A ventilation roof contains: at least one frame and multiple stop members. The at least one frame includes at least one top sheet, at least one bottom sheet, at least one internal fence, and at least one hollow portion. The at least one top sheet has at least one air vent defined along a vertical direction, one of the at least one internal fence has an air inlet extending from a horizontal direction and communicating with the at least one air vent and the at least one hollow portion, and each of the at least one internal fence has multiple recesses. The multiple stop members are retained in the multiple recesses and are crisscross accommodated in the at least one hollow portion so that at least one zigzag channel forms in the at least one hollow portion.

What is claimed is: 
     
         1 . A ventilation roof comprising:
 at least one frame including at least one top sheet, at least one bottom sheet, at least one internal fence, and at least one hollow portion surrounded by the at least one top sheet, the at least one bottom sheet, and the at least one internal fence, wherein the at least one top sheet has at least one air vent defined along a vertical direction, the at least one internal fence has at least one air inlet extending from a horizontal direction and communicating with the at least one air vent and the at least one hollow portion, and each of the at least one internal fence has multiple recesses; and   multiple stop members retained in the multiple recesses, extending upward, and crisscross accommodated in the at least one hollow portion so that at least one zigzag channel forms in the at least one hollow portion.   
     
     
         2 . The ventilation roof as claimed in  claim 1 , wherein each of the at least one stop member includes a first segment retained in each of the multiple recesses, and each stop member includes a second segment opposite to the first segment, wherein each stop member is obliquely and oppositely fixed in each of the at least one hollow portion and tilts upward along a horizontal direction, and a tilted angle of each stop member is less than 45 degrees. 
     
     
         3 . The ventilation roof as claimed in  claim 2 , wherein a distal portion of the second segment extends upward along the vertical direction. 
     
     
         4 . The ventilation roof as claimed in  claim 1 , wherein two second segments of two adjacent stop members are crisscross arranged. 
     
     
         5 . The ventilation roof as claimed in  claim 1 , wherein one of the at least one stop member proximate to each of the at least one air inlet is located on a side of each internal fence on which each air inlet is defined. 
     
     
         6 . The ventilation roof as claimed in  claim 1 , wherein each of the at least one zigzag channel is a flowing path in which airs flow along the air inlet, each of the at least one two stop member, and each of the at least one air vent. 
     
     
         7 . The ventilation roof as claimed in  claim 1 , wherein each of the at least one stop member includes multiple drainage holes. 
     
     
         8 . The ventilation roof as claimed in  claim 1 , wherein each of the at least one bottom sheet has a water outlet in communication with each of the at least one hollow portion.
