Embodiment 1

[0034] Such as figure 1 As shown, the environment-friendly combustible gas firecracker of this embodiment includes an air storage bag 2 and an explosion device 3 .

[0035] Such as figure 2 As shown, the surface of the air storage bag 2 is provided with reinforcing ribs using hot-melt technology to prevent the air storage bag 2 from bursting from the middle. The two ends of the air storage bag 2 are sealed by ultrasonic welding, and this is used as a weak point and a sound gathering structure. The air storage bag 2 is a sac-shaped structure with both ends sealed. The interior of the air storage bag 2 is filled with atmospheric pressure combustible gas. The volume expansion of the normal pressure combustible gas is nearly ten thousand times that of gunpowder combustion. The volume expansion of the normal pressure combustible gas after combustion is It is only thermal expansion, the volume of the actual reactant is reduced, and the expansion disappears rapidly as the temperat...

Embodiment 2

[0043] Such as image 3 and 4 As shown, this embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the environmentally friendly combustible gas firecrackers in this embodiment also include an external sound-gathering shell 1, and an external sound-gathering shell 1 It has a tubular structure, and the two ends of the external sound collecting shell 1 are respectively provided with sound collecting ports 11 . The external sound collecting shell 1 is sheathed on the outer periphery of the air storage bag 2, and the length of the external sound collecting shell 1 is slightly longer than that of the air storage bag 2, so as to ensure that all the air storage bags 2 are inside the external sound collecting shell 1. The explosion sound generated by the explosion of the air storage bag 2 is transmitted outward through the sound gathering port 11, and the sound gathering port 11 can enhance the explosion sound to make the sound of firecra...

Abstract

The embodiment of the invention relates to an environment-friendly flammable gas firecracker and a firecracker string and relates to the technical field of fireworks and firecrackers. The environment-friendly flammable gas firecracker comprises a gas storage bag and an igniting device. The gas storage bag is internally filled with flammable gas. The igniting device comprises an embedded electrodeand two external electric leading devices, the embedded electrode is arranged in the gas storage bag, the two external electric leading devices are arranged at the outer two ends of the gas storage bag respectively, and the two external electric leading devices and the two ends of the embedded electrode are spaced through the bag wall of the gas storage bag respectively. The environment-friendly flammable gas firecracker has the advantages of being high in safety, small in environment pollution, extremely low in explosive capacity, long in gas storage time and good in continuous burning and explosion stability.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers, in particular to an environment-friendly combustible gas firecracker and a string of firecrackers. Background technique [0002] The origin of firecrackers has a history of more than 1,000 years. When there was no gunpowder and paper, the ancients used fire to burn bamboo to make it burst and make sound to expel the god of plague. This is of course a folk legend, but it reflects the good wishes of the ancient Chinese people who longed for peace and prosperity. Firecrackers have different names in various historical periods, and the appellations range from firecrackers, firecrackers, firecrackers and braided artillery to firecrackers. In modern times, people almost always set off firecrackers on occasions such as traditional festivals, wedding celebrations, various celebrations, and temple fairs. Especially during the Spring Festival, the consumption of firecrackers exceeds ha...
