In order to achieve the above and other objects, the present invention provides an exhaust hood structure with lighting function, comprising:

the exhaust hood structure with lighting function is mainly characterized by comprising an exhaust hood body arranged outside an exhaust outlet of a roof, wherein the exhaust hood body comprises a short-edge outer hood body and a long-edge outer hood body which are respectively arranged on two sides;

the long-side outer cover body is divided into an upper inclined section and a lower inclined section, and a downward-arranged back hook baffle is connected to the topmost end of the upper inclined section of the long-side outer cover body;

and the topmost end of the short-edge outer cover body is connected with an upper inclined guide plate extending into the exhaust cover body;

light transmission plates are embedded in the upper inclined section and the short-edge outer cover body;

an air outlet is formed between the upper inclined guide plate and the back hook baffle;

at least one rain baffle is additionally arranged at the air outlet;

the lower end of the upper inclined guide plate is provided with a side guide plate and a lower inclined guide plate, the side guide plate and the lower inclined guide plate are in a connected state, the lower inclined guide plate extends to the inner side of the lower inclined section of the long-edge outer cover body to be connected with the lower inclined section, and a drain hole is formed in the joint of the lower inclined guide plate and the lower inclined section.

Adopted the utility model discloses a compromise exhaust hood structure of daylighting, through the outer outside air current's of minor face outer cover body or long limit outer cover water conservancy diversion, can drive the air flow of air outlet, like this the steam of roof air exit will be inhaled by the air current in the lump, consequently steam is derived extremely again through the return air section promptly the air outlet, and in the exhaust hood body weather shield, go up the infiltration of oblique baffle then can effectively completely cut off outside rainwater with oblique baffle down to the rainwater with a small amount of infiltration is discharged from the wash port, simultaneously, the light-passing board of establishing is then for the inside illumination that provides natural daylighting of building to inlay on the minor face outer cover body and the long limit outer cover body. The utility model discloses a compromise exhaust hood structure of daylighting is for the molding to various building upper portions, all applicable exhaust apparatus, and gives the more smooth and easy circulation effect of hot-air. And through the design that the exhaust hood structure is provided with the rain shield, the rain shield can effectively shield and prevent rainwater from being directly sprayed into the exhaust hood body, so that a good waterproof effect is achieved. And aiming at the lighting of the upper part of the building, the design that the light-transmitting plate is embedded in the outer cover body is provided, so that the interior of the building can be illuminated by natural lighting.
