Abstract
The utility model discloses a turriform prevents flowing backward cap of airing exhaust, cover, prevent wind drainage circle and hood seat to constitute including rain -proof, its characterized in that, hood seat top is connected one row and is prevent wind the drainage circle, prevent wind drainage circle top and connect rain -proof lid, rain -proof lid, prevent wind and be connected through the bracing piece between drainage circle and the hood seat, the utility model discloses because rain -proof lid is inside for the toper, can reduced drag, draw streams of emanating, prevent wind the drainage circle through 360 degrees domatic flashing boards with one row, utilize siphon principle can prevent that the natural wind from can not flow backward into, there is the production of great negative pressure moreover, the assistant airs exhaust, and simple structure, material are sparingly.
Description
Technical field
The utility model relates to a kind of Wind discharging hat, is specially a kind of turriform reverse-filling Wind discharging hat.
Background technology
Declare according to World Health Organization, kitchen and washroom are that the chief-criminal of indoor pollution brings disaster upon hand, and kitchen fume pours in down a chimney, washroom returns taste, Yi Shi China even sting in one's heart of a lot of family in the whole world, and the fire incident more having natural gas leaking to cause constantly occurs.Major part high residential building does not all have good way that those dirty gases are all discharged up hill and dale, tracing it to its cause is exactly the good blast cap of the public smoke vent in kitchen and washroom public exhaust duct top neither one, and the smoke evacuation caused, air draft not smooth and outdoor wind-fall is filled with and caused.More regrettably most of owner does not understand wherein principle, so these problems are often checked by lampblack absorber and floor drain.Current China still continues to use a lot of residential houses the cement blast cap of sixties design, although some employs unpowered rotation blast cap, this blast cap, in non rotating situation, but produces very large resistance; Greasy dirt between blade gap is difficult to cleaning; Lubrication oil easily damages by thermal evaporation bearing; And not anti-strong wind, and existing blast cap is not windproof bad, is exactly rainproof not all right; Accomplish windproof, rain is all right, the resistance that blast cap itself produces is too large again, for this reason, we provide a kind of turriform reverse-filling Wind discharging hat.
Utility model content
The purpose of this utility model is to provide a kind of turriform reverse-filling Wind discharging hat, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of turriform reverse-filling Wind discharging hat, comprise rain-proof cover, windproof drainage circle and blast cap seat to form, described temperature inductor is located at described blast cap seat inner chamber with fire prevention stop valve, described blast cap seat top connects the windproof drainage circle of a row, described windproof drainage circle top connecting rain-proof lid, described rain-proof cover, windproof drainage circle are connected by support bar with between blast cap seat.
Preferably, the number of described windproof drainage circle is three, and described windproof drainage circle is located between described rain-proof cover and blast cap seat from top to bottom successively, connecting rain-proof plate bottom described windproof drainage circle, described flashing board shape is 360 degree of domatic covering of the fans, and distance between described windproof drainage circle is identical.
Preferably, described rain-proof cover, windproof drainage circle and blast cap seat all adopt stainless steel to make, and described rain-proof cover shape is circular arc, and interior shape is taper.
Preferably, described support bar number be four, and be evenly distributed on described rain-proof cover, between windproof drainage circle and blast cap seat.
Compared with prior art, the beneficial effects of the utility model are: this turriform reverse-filling Wind discharging hat is taper because rain-proof cover is inner, resistance, injection air-flow can be reduced, windproof drainage circle is arranged by 360 degree of domatic flashing boards and one, utilize siphon principle can prevent natural wind from can not pour in down a chimney into, and having larger negative pressure to produce, assistant's air draft, structure is simple, material is saved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model blast cap seat sectional view.
In figure: 1 rain-proof cover, 2 windproof drainage circles, 3 blast cap seats, 4 flashing boards, 5 support bars.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of turriform reverse-filling Wind discharging hat, comprise rain-proof cover 1, windproof drainage circle 2, form with blast cap seat 3, described blast cap seat 5 top connects the windproof drainage circle 2 of a row, described windproof drainage circle 2 top connecting rain-proof lid 1, described rain-proof cover 1, windproof drainage circle 2 are connected by support bar 5 with between blast cap seat 3.
The number of described windproof drainage circle 2 is three, described windproof drainage circle 2 is located between described rain-proof cover 1 and blast cap seat 3 from top to bottom successively, connecting rain-proof plate 4 bottom described windproof drainage circle 2, described flashing board 4 shape is 360 degree of domatic covering of the fans, and distance between described windproof drainage circle 2 is identical, the efficiency of air draft can be improved by multiple windproof drainage circle 2, described rain-proof cover 1, windproof drainage circle 2 all adopts stainless steel to make with blast cap seat 3, described rain-proof cover 1 shape is circular arc, interior shape is taper, due to rain-proof cover 1, windproof drainage circle 2 all adopts stainless steel to make the application life extending Wind discharging hat with blast cap seat 3, described support bar 5 number be four, and be evenly distributed on described rain-proof cover 1, between windproof drainage circle 2 and blast cap seat 3, rain-proof cover 1 can be fixed by support bar 5, connection between windproof drainage circle 2 and blast cap seat 3.
The utility model improves and is: the composition of turriform blast cap is made up of several original papers such as rain-proof cover 1, windproof drainage circle 2 blast cap seats 3, and structure is very simple.Whole blast cap likeness in form tower morphological appearance air, top is rain-proof cover 1, and centre is windproof drainage circle 2, and connect 360 degree of domatic flashing boards bottom windproof drainage circle 2, bottom is blast cap seat 3.The wind that windproof drainage circle 2 and 360 degree of domatic flashing boards utilize siphon principle can not only block horizontal direction blows in exhaust duct, that the wind blowed in the external world changes direction more cleverly, make that blast cap is inside and outside has occurred pressure differential, allow in blast cap and create negative hydrostatic pressure, form suction effect.The wind that any direction is blown in face of blast cap, when the gap by windproof drainage circle 2, all creates suction force.So, blast cap not only plays rainproof, windproof, fireproof effect, to the more important thing is and the good wind energy by the external world becomes power and (suction force) can help smoke evacuation, air draft, achieve that structure is simple, material is saved, batch production, practical inexpensive object.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
