Description
Technical field
The utility model is related to constructure ventilation technical fields, specially building ventilation mouth.
Background technology
In usual architectural design, the ventilation duct road junction of building ventilation setting, conventional design is that the round tube used is said
Mouthful, for windproof and rain and snow, keep off the rain cover board or windproof screen can be also installed in the top of pipe outlet.But it is this
Traditional protective device, can have to pipe outlet it is certain block, influence the air-flow of pipeline, in addition, since four seasons wind direction is different,
Or can cause certain rainwater pour in down a chimney or wind direction flow backwards.
Utility model content
In view of the above technical problems, the utility model provides a kind of building ventilation mouth of reverse-filling, and specific technical solution is：
Building ventilation mouth, including vertical ventilation duct and sleeve, the sleeve lining are equipped with annular convex platform, annular convex platform
Internal diameter be not more than the internal diameter of ventilation duct, on sleeve is sleeved at the top of ventilation duct, sleeve and ventilation duct coaxial inner conductor, the annular
Boss is placed on ventilation duct top, and the sleeve can be rotated relative to ventilation duct along Pivot Point Center line；The sleeve one
Side is provided with horizontal erecting bed, and horizontal hinge is provided on erecting bed, and the sleeve top surface passes through hinge hinged lid
Plate, the cover board is in self gravitation effect lower cover at the top of sleeve；Wind deflector is also equipped on the sleeve, described leads
Aerofoil is streamlined structure, and one end is the tip of sealing, and the other end is opening, and tip is mounted on erecting bed, and wind deflector is located at
It is open towards consistent with cover board opening direction above the sleeve.
The wind deflector upper surface is additionally provided with vertical empennage, and the empennage is mounted on the center line of wind deflector.
The empennage is mounted on the open top of wind deflector.
It is additionally provided with annular retaining ring at the top of the sleeve, the annular retaining ring is located at the periphery of cover board.
Building ventilation mouth provided by the utility model, the gas in building can ensured with the cover board of reverse-filling by using
When flowing smooth outside air draft, external sleet and wind are not in pour in down a chimney, and wind deflector is also set up on top, front end it is open compared with
The pointed portion of rear end is big, there is difference in areas so that pressure difference is generated when the nozzle of ventilation duct has air-flow to export from the bottom to top, favorably
Flowed outwardly in the gas in guiding ventilation duct, and sleeve is movably arranged on ventilation duct, can according to wind direction adjust automatically,
So that tip windward, further avoids pouring in down a chimney phenomenon.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face in conjunction with specific embodiments and diagram, the utility model is expanded on further.
As shown in Figure 1, building ventilation mouth, including vertical ventilation duct 6 and sleeve 1,1 inner wall of sleeve are equipped with annular
Boss 10, the internal diameter of annular convex platform 10 are not more than the internal diameter of ventilation duct 6, and sleeve 1 is sleeved on 6 top of ventilation duct, sleeve 1 and ventilation
6 coaxial inner conductor of pipe, the annular convex platform 10 are placed on 6 top of ventilation duct, and the sleeve 1 can be along relative to ventilation duct 6
Pivot Point Center line rotates；1 side of sleeve is provided with horizontal erecting bed 11, and horizontal hinge is provided on erecting bed 11
7,1 upper surface of sleeve is pushed up in self gravitation effect lower cover in sleeve 1 by 7 hinged closures 3 of hinge, the cover board 3
Portion；Cover board 3 can be washed open when having air-flow in ventilation duct 6, effectively be outflowed, 3 meeting of cover board when airless in ventilation duct 6
It is closed by the gravity of itself.
Wind deflector 4 is also equipped on the sleeve 1, wind deflector 4 is that a tablet is bent into streamlined structure, and one end is
The tip 8 of sealing, the other end are opening 9, and tip 8 is mounted on erecting bed 11, and wind deflector 4 is located at 1 top of sleeve, opens
Mouth 9 is open towards with cover board 3 towards consistent.The area of 9 opening of opening is more than the projected area of tip 8, has air-flow in ventilation duct 6
When by exporting, can pressure difference be generated due to the area discrepancy between opening 9 and tip 8, be conducive to the gas for guiding ventilation duct 6 to export
It flows outwardly to.Under the action of the wind, sleeve 1 can rotate, and tip 8 is smaller, and windward, opening 9 is compared with conference by wind to leeward one
Side, 4 lower section of such wind deflector would not enter the wind, and wind deflector 4 is that the cover board 3 of lower section plays the function of keeping out the wind with rain cover.
4 upper surface of wind deflector is additionally provided with vertical empennage 5, and the empennage 5 is mounted on the center line of wind deflector 4
On.
The empennage 5 is mounted on 9 top of opening of wind deflector 4.Empennage 5 plays the role of wind vane so that wind deflector 4
Can be in time according to wind direction adjustment direction, and the stability of tip 8 windward is kept in wind.
1 top of sleeve is additionally provided with annular retaining ring 2, and the annular retaining ring 2 is located at the periphery of cover board 3.Annular gear
Circle 2 can prevent wind from uncapping plate 3.
