Abstract
The utility model introduces a succedaneum-gas gun for a firecracker, comprising an air-proof type housing and compressed air or dry ice or oxygen gas propellant or hydrogen gas propellant filled in the inner chamber of the housing. The casing of the gas gun is cracked under the knocking of apparent force, and gas in the casing is quickly expanded to form strong blast wave which is extruded by a chink to the outside of the casing to emit crisp and euphonious exploding noise. The tone is the same to the firecracker without smoke of gun powder, pollution and danger. The gas gun can be made into single and can also be strung and whip knotted. The strung gas guns only needed to be ignited a gas gun, then other ones can be exploded subsequently. If these gas guns are stacked at together they can be exploded together, and the sound shocks the sky.
Description
Technical field
The utility model belongs to the fireworks technical field.
Background technology
During the firecracker setting-off of known available, pyrotechnics rises from all around, and is both dangerous, again contaminated environment.Even too dangerous when producing, accident frequently takes place.So for many years, people are thirsting for a kind of safe substitute can very fast appearance always.
The utility model content
In order to satisfy this hope of the masses, the utility model has designed a kind of safe in utilization, environment is not polluted, and the same loud gas big gun of sound that sends when " setting off ".
The utility model is achieved in that a kind of gas big gun, has hermetic type shell 1, and described shell 1 inner chamber is filled with compressed air, or fills dry ice or oxygen generating agent or hydrogen propellant.Because described material dry ice, oxygen generating agent or hydrogen propellant all are a kind of gas-forming agents, and be the same with above-mentioned compressed air, at the certain air pressure of housing inner chamber generation of sealing.If external force collision gas big gun housing is arranged to splitting, because the housing inner and outer air pressure is inconsistent, the housing internal gas pressure is more much higher than the outer atmospheric pressure of housing, so housing inner high voltage gas can expand rapidly, formation huge impact ripple is gone out external by the crack, thereby sends the clear and melodious melodious blast sound.The same firecrackers of sound but do not have the smoke of gunpowder of firecrackers, so do not pollute yet, and are safe from danger yet, and are fool proof.
As toy or as commodity, this gas big gun of the present utility model can be made single, also can make a plurality of bunchiness and promptly tie whip. when the gas big gun of bunchiness knot whip uses " if lighting " one of them, a cracking and blast are followed in one of the meeting under the effect of shock wave of other gas big gun, if gas big gun is in heaps stacks in flakes for these, so will implosion in flakes in heaps, sound shake day.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model gas big gun.
Among the above-mentioned figure, 1-shell, 2-compressed air.
The specific embodiment
Embodiment 1: referring to accompanying drawing, moulding and annotating diameter is 10 millimeters with holes spherical shell 1 housing, injects 0.01 gram compressed air 2 by the hole in housing, and the sealing of hole of waxing promptly becomes single finished product gas big gun.A plurality of finished product gas big gun polyphone knot whips promptly become finished product gas big gun whip.
Embodiment 2: the polyurethane rubber film punch forming of getting thickness and be 0.04 millimeter is that diameter is 10 millimeters a hemispherical case body, insert 0.01 gram dry ice or oxygen generating agent or hydrogen propellant in the housing inner chamber, get another shell and close lid with it, mold pressing or the single finished product gas big gun of gummed sealing promptly becoming.A plurality of finished product gas big gun polyphone knot whips promptly become as above example of finished product gas big gun whip.
Claims (1)
1, a kind of gas big gun has hermetic type shell (1), it is characterized in that described shell 1 inner chamber is filled with compressed air (2) or dry ice or oxygen generating agent or hydrogen propellant.
