Air firecracker and firecracker string thereof

Abstract

The invention discloses an air firecracker and a firecracker string thereof. The air firecracker and the firecracker string thereof are simple in structure and low in manufacturing cost and can generate explosion sound by releasing compressed air out of an explosion opening so as to realize a firecracker explosion effect; no gunpowder is needed; a firecracker body comprises a plurality of elasticballs, so the air firecracker can realize a continuous sounding effect; the elastic balls are bounded out of the firecracker to realize a lifelike dynamic effect; and after the air firecracker is used, a check valve is pushed to the explosion opening by air pressure and seals the explosion opening so as to prevent escape of the compressed air. Repeated reutilization can be realized by reinstallingthe elastic balls or an end cover. The firecracker and the firecracker string thereof disclosed by the invention are applied to the fields of environment-friendly firecrackers, fireworks and the like.

Description

technical field [0001] The invention relates to the fields of environment-friendly firecrackers, fireworks and the like, in particular to an air firecracker and a firecracker string thereof. Background technique [0002] Firecrackers have a long history. Setting off firecrackers has become an important part of the ceremony held by the Chinese nation to celebrate the grand ceremony. This ceremony supports the common beliefs and dreams of Chinese people all over the world, and has become the traditional culture of the Chinese nation. [0003] However, most of the traditional explosive firecrackers currently on the market are piled up during production or transportation. Once the firecrackers explode, the harm is very huge, and not only seriously pollutes the environment when they are set off, but also may injure people and cause fires. Since traditional firecrackers are disposable consumables and cannot be reused, a large amount of garbage is left after setting off, which also...

AI Technical Summary

Problems solved by technology

Although when the above-mentioned firecrackers are detonated, the explosion is limited inside the explosion tube, and most of the burning material is limited in the explosion tube by the net cover, but there is still a part of the burning material that will leak out through the net cover, and the explosive gas generated after the gunpowder burns Harmful gases such as SO 2 , CO, etc. will leak out to pollute the air
