Abstract
The utility model relates to a chimney hood capable of preventing gas poisoning, which comprises a wind baffle right aligned with an outlet of a chimney, a surrounding hood sheathed at the position of the outlet of the chimney, a smoke discharging space and a smoke discharging opening. The smoke discharging space is formed through the surrounding of the wind baffle and the surrounding hood, the smoke discharging opening opposite to the wind baffle runs through the smoke discharging space, the surrounding hood is provided with rows of smoke discharging holes, and the smoke discharging holes run through the smoke discharging space from multiple directions. With simple structure, low cost and convenient use, the chimney hood can effectively prevent backflow of smoke due to that the chimney bears wind blown from multiple directions, thereby effectively avoiding gas poisoning death caused by backflow of smoke, and reducing smoke pollution at the same time.
Description
[technical field] the utility model relates to a kind of chimney cap, relates in particular to a kind of structure of the chimney cap that guards against gas poisoning.
[background technology] is present, and known civilian chimney is easy to down cigarette in stronger facining the wind, and existing chimney does not all stop the chimney cap that wind direction is not surveyed.Unfixed like this wind direction is easy to cause down cigarette, and it is indoor to cause carbon monoxide to be imported by chimney, thereby causes people's gas poisoning.
[utility model content] the purpose of this utility model is to provide a kind of can preventing to blow the chimney cap that guards against gas poisoning that the wind that comes causes down cigarette and reduces smoke contamination because of each face.
For achieving the above object, the utility model is realized by following scheme: the smoke evacuation space that a kind of chimney cap that guards against gas poisoning comprises deep bead over against the outlet of chimney, is set in the shroud in the exit of chimney, surrounded by described deep bead and shroud, and relative with described deep bead and connect the exhaust opening in described smoke evacuation space, described shroud is provided with the some exhaust smoke holes that connect described smoke evacuation space from a plurality of directions.
The utility model is simple in structure, cost is low, and is easy to use, by deep bead, shroud, smoke evacuation space, exhaust opening being set, reaching some exhaust smoke holes, can prevent effectively that chimney from scraping the cigarette that falls that the down draught that comes causes because of each face, thereby avoid effectively falling the gas poisoning death incident that cigarette causes because of chimney.By described deep bead and shroud are set, can stop that the larger particles in the flue dust is discharged in the air in addition, thereby reduce smoke contamination.
[description of drawings] Fig. 1 meets the structural representation that the chimney cap that guards against gas poisoning of the present utility model is set in the exit of chimney.
Below in conjunction with accompanying drawing the utility model is further specified.
[specific embodiment] Fig. 1 has disclosed and has met a kind of chimney cap that guards against gas poisoning 1 of the present utility model.The chimney cap that guards against gas poisoning 1 is made by iron sheet, and it can be set in the exit of chimney 2.The described chimney cap that guards against gas poisoning 1 is designed to cylindrical in the present embodiment, can certainly be designed to other shapes, as triangular prism shaped, four prism type or the like.The described chimney cap that guards against gas poisoning 1 comprises deep bead 10, shroud 20, smoke evacuation space 100, reaches exhaust opening 200.
Described deep bead 10 is over against the outlet setting of chimney 2.Described shroud 20 is set in the exit of chimney 2, and surrounds smoke evacuation space 100 with described deep bead 10.Described shroud 20 is provided with the some exhaust smoke holes 21 that connect described smoke evacuation space 100 from a plurality of directions.The part of described some exhaust smoke holes 21 between the exit that is in described deep bead 10 and described chimney 2 on the described shroud 20 is sparse distribution, and is arranged on the position that certain distance is arranged with the outlet of described chimney 2; The part of described some exhaust smoke holes 21 between the exit of described exhaust opening 200 and described chimney 2 is intensive distribution.Described exhaust smoke hole 21 is arranged according to aforementioned manner and can be prevented to irritate down draught from exhaust smoke hole 21.
Described shroud 20 also is provided with the support 22 that is used for fixing the described chimney cap that guards against gas poisoning 1 on chimney 2.Described support 22 be arranged on described exhaust opening 200 near.
The chimney cap that guards against gas poisoning described in the utility model 1 is simple in structure, and cost is low, and is easy to use, can be used on the device or equipment of various needs smoke evacuations, for example domestic briquet stove, gas furnace, water heater and boiler plant or the like.The described chimney cap that guards against gas poisoning 1 can prevent effectively that chimney from scraping the cigarette that falls that the down draught that comes causes because of each face, thereby avoids effectively falling the gas poisoning death incident that cigarette causes because of chimney.By described deep bead 10 and shroud 20 are set, can stop that the larger particles in the flue dust is discharged in the air in addition, thereby reduce smoke contamination.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
