The utility model content:
The utility model purpose provides a kind of building exhast duct fresh air inlet and gutter water inlet double-edged fine-toothed comb, makes simple, easy for installation, good looking appearance, can not get rusty, and have wind-shielding function, prevents that flue gas from pouring in down a chimney, and solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: form building exhast duct fresh air inlet and gutter water inlet double-edged fine-toothed comb by double-edged fine-toothed comb frame and double-edged fine-toothed comb net, the double-edged fine-toothed comb frame is divided into double-edged fine-toothed comb housing and double-edged fine-toothed comb lower frame two parts, the mutual interlock coupling of double-edged fine-toothed comb housing and double-edged fine-toothed comb lower frame, form the mother-son mouth structure, the double-edged fine-toothed comb net is engaged between double-edged fine-toothed comb housing and the double-edged fine-toothed comb lower frame, and double-edged fine-toothed comb lower frame and exhast duct fresh air inlet and gutter water inlet are complementary.
The double-edged fine-toothed comb housing can be enclosed within on the double-edged fine-toothed comb lower frame, and the double-edged fine-toothed comb housing is female mouthful, and the double-edged fine-toothed comb lower frame is the rim of the mouth, is interlocked, and the double-edged fine-toothed comb net is engaged between double-edged fine-toothed comb housing and the double-edged fine-toothed comb lower frame.The double-edged fine-toothed comb lower frame also can be enclosed within on the double-edged fine-toothed comb housing, and the double-edged fine-toothed comb lower frame is female mouthful, and the double-edged fine-toothed comb housing is the rim of the mouth, is interlocked, and the double-edged fine-toothed comb net is engaged between double-edged fine-toothed comb housing and the double-edged fine-toothed comb lower frame.
In order to prevent that the flue gas in the exhast duct from pouring in down a chimney, in the double-edged fine-toothed comb lower frame, be provided with some " L " shape draught shield, the opening direction of draught shield makes progress, and under the effect of draught shield, the flue gas in the building exhast duct is difficult to pour in down a chimney into the room by fresh air inlet.
Adopt the utility model, because the mother-son mouth mode of employing double-edged fine-toothed comb housing and the mutual interlock of double-edged fine-toothed comb lower frame is the double-edged fine-toothed comb net fixedly, make simple, easy for installation, good looking appearance, can adopt the one-shot forming of PVC material to make double-edged fine-toothed comb housing and double-edged fine-toothed comb lower frame, make whole double-edged fine-toothed comb easy more attractive in appearance, can not get rusty; The material of double-edged fine-toothed comb net can adopt wire lath, plastic wire etc.; Double-edged fine-toothed comb frame and double-edged fine-toothed comb net also can adopt other material that is fit to.Building exhast duct fresh air inlet and gutter water inlet are arbitrarily with the shape of double-edged fine-toothed comb, match according to the shape of fresh air inlet and water inlet, can be shapes such as circular, square, changeable shape.
The utlity model has rational in infrastructure, make simple, easy for installation, good looking appearance, can not get rusty, characteristics such as prevent that flue gas from pouring in down a chimney, go for reserving exhast duct in prefabricated exhast duct, the body of wall, PVC moulds pipe exhast duct, building water drain pipe water mouth etc.
