Description
Technical field
The utility model belongs to the scavenging arrangement field, especially relates to the rainproof noise reduction inlet duct of a kind of metope.
Background technology
The air-tightness of modern building is become better and better, and makes that room air is difficult in time exchange with extraneous fresh air.Some construction materials can discharge the healthy gas that is harmful to health, and guarantee indoor air quality, must need to set up outdoor and indoor air duct.At present, normally on the metope of building, all be provided with air inlet, as the passage of indoor-outdoor air circulation.But in the time of air inlet, can follow entering and rainproof problem of noise.For solving these several persons' contradiction, different products has different schemes.Yet prior art is failed solution ventilation, sound insulation and rainproof these three problems of fine while, so the utility model is devoted to design a kind of in air inlet, has rainproof preferably and scheme noise reduction.
Summary of the invention
It is a kind of for the indoor-outdoor air rainproof noise reduction inlet duct of needed metope that circulates that the purpose of this utility model is to provide, and in air inlet, rainproof preferably and noise reduction arranged.
For achieving the above object, the utility model adopts following technical scheme: the rainproof noise reduction inlet duct of a kind of metope, comprise base and cover, and described base is provided with air inlet, and described base and cover are provided with the connector that cooperatively interacts; The diameter of described cover is greater than the diameter of described base; The edge of described cover is provided with to the extension of base direction and covers the edge; The edge of described base is provided with retaining ring to the extension of cover direction, and described retaining ring is provided with blow vent; The height on described lid edge less than the height of described retaining ring.In this structure, after base and cover junction button get togather, because the diameter of cover is greater than the diameter of base, and the height on lid edge less than the height of retaining ring, therefore between cover and metope, formed the air inlet duct of a side, after entering from air inlet duct, air, guaranteed the circulation of room air through in the blow vent inlet chamber.The front quilt cover cap seal of air inlet of the present utility model is stifled, and rainwater, air, noise all can not pass through, and noise stops through cover, and twice oppositely also big high attenuation of obstruct of process air inlet duct.And the retaining ring of the lid edge of cover and base also effectively blocks entering of rainwater.
As improvement, described retaining ring towards the diameter of the opening of cover direction greater than its diameter towards the opening of base direction.In this structure, because retaining ring greater than its diameter towards the opening of base direction, promptly makes retaining ring be tilted by the export-oriented metope of wall towards the diameter of the opening of cover direction, forms a sluicing groove between retaining ring and the metope thereby make, when rainwater enters this position, can discharge smoothly.In addition, the concrete shape of retaining ring can be as horn-like or bowl-shape.
As improvement, described blow vent is located at the below of retaining ring.Because blow vent is located at the below of retaining ring, rainwater can only run underneath to outdoor and can't enter in the retaining ring along the outer wall of retaining ring.
As improvement, the air inlet of described base is provided with intubate to the extension of metope direction.Because base has the intubate that matches with the metope preformed hole, can be installed in easily on the metope preformed hole.
As improvement, the air inlet of base is provided with the sealing platform towards the extension of cover direction.When rainwater was big especially, the water of the blow vent that splashes can be blocked and can't enter in the air inlet by the sealing platform.
As improvement, the air inlet of base is provided with the waterproof blinds.
As further improvement, described waterproof blinds is directed downwards inclination by base to cover.When rainwater was big especially, waterproof blinds can prevent from the to splash water of blow vent entered in the air inlet, further guarantees the water proofing property of this product.
As specializing, described retaining ring is provided with leg to the cover direction, and described leg is provided with buckle.
As specializing, described cover is provided with the draw-in groove that matches with described buckle towards the one side of base.Above-mentioned buckle and this draw-in groove have greatly made things convenient for cover to be installed on the base, have improved installation effectiveness.
Compared with prior art, the utility model has solved in air inlet, and the problem of rainproof and noise reduction is for resident family provides a good home environment.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
To shown in Figure 6, the rainproof noise reduction inlet duct of a kind of metope comprises base 1 and cover 2 as Fig. 1, and described base 1 is provided with air inlet 11.The diameter of described cover 2 is greater than the diameter of described base 1; The edge of described cover 2 is provided with lid along 21 to the extension of base 1 direction.The edge of described base 1 is provided with trumpet-shaped retaining ring 12 to the extension of cover 2 directions, is provided with blow vent 13 below described retaining ring 12.And the height of described lid along 21 less than the height of described retaining ring 12.And form a sluicing groove 3 (as shown in Figure 7) between trumpet-shaped retaining ring 12 and the metope 4, when rainwater enters this position, can discharge smoothly.
Be provided with leg 17 at retaining ring 12 to cover 2 directions, described leg 17 is provided with buckle 18; Described cover 2 is provided with the draw-in groove 22 that matches with described buckle 18 towards the one side of base 1.Above-mentioned buckle 18 and draw-in groove 22 have greatly made things convenient for cover 2 to be installed on the base 1, have improved installation effectiveness.
As shown in Figure 7, during installation, the preformed hole 41 with intubate 14 insertion metopes 4 is fastened on cover 2 on the base 1 again.Enter blow vent 13 behind the air inlet duct 5 of air through the side, pass through again in air inlet 11 inlet chambers, guaranteed the circulation of indoor-outdoor air, make resident family that pure and fresh room air be arranged; And in air inlet, the problem of the rainproof and noise reduction that structure of the present utility model has better solved is for resident family provides a good home environment.
Above content only be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that the specific embodiment of the present utility model is confined to these explanations.For the person of an ordinary skill in the technical field, the some simple deduction or replace of making all should be considered as belonging to the scope that the utility model is protected.
