Angle is in 65 °.
It should be noted that the block piece 41 of the outer wall of baffle plate 4 set it is multiple, so multiple block pieces 41 are formd and are similar to
The structure of shutter, air draft is carried out for smokejack, while the effect kept off the rain can also be played.
In the present embodiment alternative, baffle plate 4 could be arranged to one or more；
The first：Baffle plate 4 is arranged to one, and baffle plate 4 is located at close to the side of fan outlet, the blast cap that keeps off the rain it is another
Outer three side is used to discharge the waste gas inside smokejack, ensures the flowing that gas can be unobstructed.
Second：Baffle plate 4 is arranged to multiple, and fan outlet can ensure gas energy close to any one baffle plate 4
Enough unobstructed flowings.
In the present embodiment alternative, top plate 1 is included positioned at the first top plate 1 of the center section of top plate 1 and positioned at first
Second top plate 1 of the surrounding of top plate 1, wherein the second top plate 1 is fixedly connected with the first top plate 1.
Specifically, the surface of the first top plate 1 is in planar structure, and with the junction of the second top plate 1 also into round and smooth structure, can
Avoid stabbing birds.
Further, 1 inclined structure of the second top plate, can be such that rainwater quickly leaves, and avoid rainwater from being trapped in the table of top plate 1
Face.
It should be noted that the trapezoidal structure of the section of top plate 1, the wind loading rating of top plate 1 can be effectively improved.
In the present embodiment alternative, the lower section of top plate 1 is provided with the deflector 5 that guide functions are played to air, deflector 5
It is fixedly connected with supporter 2；The setting of deflector 5 can effectively reduce windage.
Specifically, deflector 5 is included positioned at the first deflector 51 of the center section of deflector 5 and positioned at the first deflector
Second deflector 52 of 51 surroundings, wherein the second deflector 52 is fixedly connected with the first deflector 51.
It should be noted that 51 structure spherical in shape of the first deflector；Can be by wind water conservancy diversion that high speed rises to surrounding, not only
Windage can be effectively reduced, air-flow is also helped and excludes the blast cap that keeps off the rain in time.
Explanation is needed further exist for, the second deflector 52 is in planar structure, and the second deflector 52 is fixed with supporter 2
Connection；Windage can be reduced.
In the present embodiment alternative, top plate 1 is fixedly connected or is detachably connected with supporter 2；
Top plate 1 is fixedly connected with supporter 2, can weld top plate 1 and supporter 2, has the advantages of being connected firmly；
Top plate 1 is detachably connected with supporter 2, when top plate 1 needs to change, can directly be disassembled top plate 1, having makes
The advantages of with facilitating.
Specifically, bottom plate 3 is fixedly connected or is detachably connected with supporter 2；
Bottom plate 3 is fixedly connected with supporter 2, can weld bottom plate 3 and supporter 2, has the advantages of being connected firmly；
Bottom plate 3 is detachably connected with supporter 2, when bottom plate 3 needs to change, can directly be disassembled bottom plate 3, having makes
The advantages of with facilitating.
Using the blast cap that keeps off the rain of the present embodiment, including top plate 1 and the bottom plate 3 for being provided with through hole, between top plate 1 and bottom plate 3
It is provided with for connecting top plate 1 and the supporter 2 of bottom plate 3；At least one piece of baffle plate 4, baffle plate 4 are also associated between top plate 1 and bottom plate 3
On be provided with multiple block pieces 41 for rain-proof, form air outlet between block piece 41 and baffle plate 4.In use, blower fan goes out
Air port carries out air draft after passing through bottom plate 3 by through hole, due to the setting of top plate 1, can avoid air outlet of the rainwater by blower fan
Into blower interior, the problem of it also avoid being flowed into inside public chimney flue, and then avoid causing common flue internal water accumulation；Again
Multiple block pieces 41 for rain-proof are provided with due to being also associated with baffle plate 4 between top plate 1 and bottom plate 3, and on baffle plate 4, are hindered
Air outlet is formed between block piece 41 and baffle plate 4, and fan outlet is positioned close to the position of baffle plate 4, so rain can be avoided
Water enters blower interior, therefore even if baffle plate 4 sets one piece, and positioned at close to the side of fan outlet, keep off the rain wind
Other three side of cap is used to discharge the waste gas inside smokejack；The wind that keeps off the rain can also be effectively improved while air draft is unobstructed
The ability of keeping off the rain of cap.
Embodiment two
The gas extraction system that the present embodiment provides, including flue, blower fan is provided with the air outlet of flue, is set on the outside of blower fan
It is equipped with the above-mentioned blast cap that keeps off the rain for protecting blower fan.
Specifically, blower fan is fixedly connected with the blast cap that keeps off the rain, wherein the connecting portion of keep off the rain blast cap and blower fan is blower fan air-out
At mouthful.
Preferably, the blast cap that keeps off the rain mainly has two kinds with the mode being fixedly connected at fan outlet：
The first：Welding at blast cap and fan outlet of keeping off the rain is in integral structure, can make to keep off the rain blast cap and blower fan
Connection is more firm.
It should be noted that the connected mode of keep off the rain blast cap and blower fan is not just for welding, or other connection sides
Formula, as long as being connected firmly between blast cap and blower fan of keeping off the rain can be made, therefore do not illustrating one by one here.
Second：The blast cap that keeps off the rain is screwed at fan outlet, i.e., with blower fan to be removable at fan outlet
Connection is unloaded, when blast cap is kept off the rain in replacing, the blast cap that will directly can keep off the rain disassembles, and has the advantages of easy to use.
It is screwed it should be noted that the connected mode of keep off the rain blast cap and blower fan can be the blast cap that keeps off the rain in blower fan
At air outlet, or other connected modes, if being connected firmly between top plate 1 and housing can be made, and can be at any time
Change or dismantle the blast cap that keeps off the rain, therefore do not illustrating one by one here.
Using the gas extraction system of the present embodiment, including flue, blower fan is provided with the air outlet of flue, is set on the outside of blower fan
It is equipped with the blast cap that keeps off the rain of above-described embodiment one for protecting blower fan.Because gas extraction system of the present utility model includes the wind that keeps off the rain
Cap, so gas extraction system can ensure effectively improve the ability of keeping off the rain for the blast cap that keeps off the rain while air draft is unobstructed；
And then avoid rainwater and the problem of causing common flue internal water accumulation is flowed into inside public chimney flue by the air outlet of blower fan.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
