Abstract
The utility model discloses a kind of wind-proof chimney cover, comprises and is nested in cylinder at the bottom of chimney top end shield, and at the bottom of described cover, the upper end of cylinder is horizontal cylinder, and ventilating duct is fixed at the two ends of described horizontal cylinder; The diameter of described ventilating duct is 0.5-1.5 times of cylinder diameter at the bottom of cover; The diameter of described horizontal cylinder is 1-1.5 times of cylinder diameter at the bottom of cover; Cylinder at the bottom of described cover and chimney can relatively rotate.The utility model has the advantages that: due to the setting of horizontal cylinder, pouring in down a chimney of rainwater can be avoided completely; Owing to being provided with the ventilating duct at two ends, add the air draft distance of chimney on the one hand, draft is increased, and on the other hand, the side of ventilating duct is enclosed construction, and therefore, wind from the side cannot enter chimney; And the wind horizontal cylinder can be attracted away from the wind that ventilating duct above-below direction is come in, therefore, thoroughly solve the problem of falling cigarette.
Description
Technical field
The utility model relates to a kind of chimney, is a kind of chimney cap specifically.
Background technology
Existing chimney, for preventing pouring in down a chimney of rainwater and wind, often arranges a rainhat on the top of chimney, but hinders the discharge of flue gas due to rainhat, brings certain influence to the draft of chimney; Secondly, because wind can pour into from the gap of rainhat and chimney, produce down draught phenomenon, this structure is widely used in the local-style dwelling houses in rural area now, and due to down draught phenomenon, the toxic gas of the carbon monoxide that burning is produced cannot be discharged, and causes gas poisoning phenomenon.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of chimney cap being placed on rainwater and wind-fall and filling with, and chimney cap disclosed in utility model is arranged on the top of chimney, can effectively solves the problems of the technologies described above.Concrete technical scheme is as follows:
A kind of wind-proof chimney cover, comprise cylinder at the bottom of the cover being nested in chimney top, at the bottom of described cover, the upper end of cylinder is horizontal cylinder, and ventilating duct is fixed at the two ends of described horizontal cylinder; The diameter of described ventilating duct is 0.5-1.5 times of cylinder diameter at the bottom of cover; The diameter of described horizontal cylinder is 1-1.5 times of cylinder diameter at the bottom of cover; Cylinder at the bottom of described cover and chimney can relatively rotate.
The length of described ventilating duct is 1.5-2 times of horizontal cylinder diameter.
The utility model has the advantages that: due to the setting of horizontal cylinder, pouring in down a chimney of rainwater can be avoided completely; Owing to being provided with the ventilating duct at two ends, add the air draft distance of chimney on the one hand, draft is increased, and on the other hand, the side of ventilating duct is enclosed construction, and therefore, wind from the side cannot enter chimney; And the wind horizontal cylinder can be attracted away from the wind that ventilating duct above-below direction is come in, therefore, thoroughly solve the problem of falling cigarette.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described, as shown in Figure 1, the utility model comprises cylinder 1 at the bottom of the cover being nested in chimney top, and the upper end of cylinder 1 at the bottom of described cover is horizontal cylinder 2, and ventilating duct 3 is fixed at the two ends of described horizontal cylinder 2; The diameter of described ventilating duct 3 is 0.5-1.5 times of cylinder 1 diameter at the bottom of cover; The diameter of described horizontal cylinder 2 is 1-1.5 times of cylinder 1 diameter at the bottom of cover; At the bottom of described cover, cylinder 1 and chimney 4 can relatively rotate.
The length of described ventilating duct 3 is 1.5-2 times of horizontal cylinder 2 diameter.
In the utility model, the setting of regarding sizes, effectively can ensure that the draft of chimney increases, as ventilating duct diameter and the relation of cover end cylinder diameter, when the diameter of ventilating duct is too large, the flowing velocity of wind reduces, can not produce the flue gas in horizontal cylinder and detach effect, can pour in down a chimney on the contrary in horizontal cylinder, therefore, each diameter of reasonable set is also one of inventive point of the present utility model.
Claims (2)
1. a wind-proof chimney cover, is characterized in that: comprise cylinder at the bottom of the cover being nested in chimney top, and at the bottom of described cover, the upper end of cylinder is horizontal cylinder, and ventilating duct is fixed at the two ends of described horizontal cylinder; The diameter of described ventilating duct is 0.5-1.5 times of cylinder diameter at the bottom of cover; The diameter of described horizontal cylinder is 1-1.5 times of cylinder diameter at the bottom of cover; Cylinder at the bottom of described cover and chimney can relatively rotate.
