Description
Technical field
Field of ventilation is the utility model is related to, particularly relates to a kind of blast cap.
Background technology
Many industrial premises, particularly color steel building, radiating condition is poor, and summer sultry exception, causes work efficiency low
Fall, deterioration in quality, such as add unpowered roof air cap, can effectively improve indoor air quality, there is provided comfortable work
Environment, promotes work efficiency；Many industry, because of the special nature of production, cause the air pollution in factory, not only environmental quality is low
Under, if things go on like this, the health of employee must come to harm, and install blast cap, and room ventilation is effect improved, can effectively protect
Health；In many fire incidents, normal someone is choked wound by dense smoke, such as installs blast cap, can discharge dense smoke in large quantities rapidly, to people more
More ground escape space, so it is also a kind of safety device.
The blast cap used in the prior art is generally made of top plate, bottom plate and side panel, and smoke outlet and cigarette are opened up on bottom plate
Road is connected, and four square ventilating openings are surrounded between top plate, bottom plate and side panel.Natural wind from one of ventilating opening scrape to
That opposite ventilating opening, the oil smoke at floss hole is driven and is discharged, and drawback present in practice is：Wind may when scraping
Part cigarette is pushed down, draft deficiency of the wind to cigarette, does not reach preferable smoke discharging effect；Natural wind is four faces from all directions
Square ventilating opening cannot use whole natural winds.
Utility model content
The utility model discloses a kind of blast cap, and ventilation effect is good, and can effective rain-proof.
The utility model is achieved through the following technical solutions：
A kind of blast cap, including it is upper cover plate, exhaust pipe, supporting beam, lower cover, fan blade, shaft, blade, bottom plate, through hole, recessed
Groove, is equipped with the supporting beam, the exhaust pipe, the exhaust is equipped with below the lower cover between the upper cover plate and lower cover
For pipe through the lower cover, the exhaust pipe lower end is equipped with the bottom plate, and the bottom plate center is equipped with the through hole, and surface is equipped with
Some grooves, place the fan blade in the groove, and the fan blade is made of the shaft and blade, the shaft insertion
In the groove, the through hole and exhaust pipe are communicated with interior, and the exhaust pipe stretches to interior always through through hole.
Preferably, the center of circle of the lower cover, exhaust pipe and through hole is on same straight line.
Preferably, each fan blade includes 4 blades.
Preferably, the upper cover plate is identical with lower cover size.
Compared with prior art, the beneficial effects of the utility model are：The blast cap of the utility model is by ventilating opening and air draft
Mouth, which is completely independent, to come, and prevents indoor section cigarette and is held down the problem of can not arranging, and ventilation effect is good, and the design of fan blade,
Rainproof effect is good.

Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of blast cap, including upper cover plate 1, exhaust pipe 2, supporting beam 3, lower cover 4, fan blade 5, shaft 51, blade 52, bottom plate
6th, through hole 7, groove 8, are equipped with the supporting beam 3 between the upper cover plate 1 and lower cover 4, the lower section of lower cover 4 is equipped with described
Exhaust pipe 2, the exhaust pipe 2 pass through the lower cover 4, and 2 lower end of exhaust pipe is equipped with the bottom plate 6,6 center of bottom plate
Equipped with the through hole 7, surface is equipped with some grooves 8, places the fan blade 5 in the groove 8, the fan blade 5 is by described
Shaft 51 and blade 52 form, and the shaft 51 is inserted into the groove 8, and the through hole 7 and exhaust pipe 2 are communicated with interior, institute
State exhaust pipe 2 and stretch to interior always through through hole 7.
The center of circle of the lower cover 4, exhaust pipe 2 and through hole 7 is on same straight line.
Each fan blade 5 includes 4 blades 52.
The upper cover plate 1 is identical with 4 size of lower cover.
No matter the natural wind in which direction blows to blast cap, blast cap can be absorbed into natural wind, the natural wind blown, through institute
State fan blade 5 to enter, got in by the through hole 7, and indoor gas (smog etc.) then discharges room by the exhaust pipe 2
Outside, the problem of air inlet mutually will not mix with outlet, be not in back pressure.
The above only expresses the embodiment of the utility model, its describe it is more specific and in detail, but can not be because
This and be interpreted as the limitation to the utility model patent scope, where within the spirit and principles of the present invention, made appoint
What modification, equivalent substitution, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent
Shield scope should be determined by the appended claims.
