Description
Technical Field
The utility model relates to a drain pipe field especially relates to a balcony ventilation air discharge cap that prevents dust.
Background
At present, the existing wind cowl is generally formed by arranging an elbow or a conical cowl at the top of an exhaust pipe, the structure of the wind cowl is too simple, when the wind and rain fall in an oblique wind, the wind and rain can easily flow backwards into the exhaust pipe, so that the normal emission of the waste gas in the exhaust pipe is prevented, and the rainwater can flow into the room along the exhaust pipe; how to ensure the normal exhaust of the exhaust pipe and avoid rainwater sundries from entering the exhaust pipe becomes a technical problem which is difficult to solve for a long time.
In view of the above, a ventilating and dust-proof exhaust cap for a balcony has been developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art, provide a dustproof air discharge cap of balcony ventilation, can effectually prevent that rainwater, debris from wafting into inside the exhaust pipe, the utility model discloses simple structure, the cost is low, and light in weight is convenient for transport the transport, and the equipment work load is little, and site operation is convenient, long service life, and occupation space is little.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a ventilating dustproof exhaust cap for a balcony comprises: the lower pipe, the middle pipe, the upper pipe, the top plate, the circular plate, the outer cover, the inserting plate and the connecting plate; the low tube top sets up the top tube, set up the well pipe of inverted circular truncated cone shape between low tube and the top tube, the periphery upper end of top tube sets up annular roof, roof upper surface middle part sets up ring shape slot, the top of roof sets up the filter mantle, the lower extreme of filter mantle corresponds with the slot of roof and inserts and close, the filter mantle upper surface sets up annular slot, the top of filter mantle sets up the dustcoat, dustcoat inner wall upper end sets up annular picture peg, the picture peg of dustcoat corresponds with the slot of filter mantle and inserts and close, the filter mantle is located the dustcoat, the low tube, well pipe, top tube and roof integrated into one piece constitute the casing, picture peg integrated into one piece in dustcoat and.
The structure of the filter cover is as follows: the upper surface of circular plate sets up the annular slot of circle, and the below of circular plate sets up the picture peg, evenly distributed connecting plate between the periphery of circular plate and the periphery of picture peg, and the diameter of circular plate is less than the periphery diameter of picture peg of circular plate below, and picture peg, the connecting plate integrated into one piece of circular plate and circular plate below.
The utility model has the advantages that: the clearance between dustcoat and the filter mantle is great, and exhaust resistance is little, makes to exhaust more smoothly, and inside the dustcoat can effectually prevent that the rainwater from wafting into the exhaust pipe, in the filter mantle can avoid debris to enter into the exhaust pipe, the utility model discloses simple structure, the cost is low, and light in weight is convenient for transport the transport, and the equipment work load is little, and site operation is convenient, long service life, occupation space is little.
