Abstract

The invention relates to a firecracker which comprises a shell, a dynamite-free fuel unit and a connector unit. The connector unit is used for applying voltage to the dynamite-free fuel unit. The dynamite-free fuel unit can generate expansion gas after the preset voltage is applied to the dynamite-free fuel unit, so that expanding pressure triggering explosion is formed. According to the firecracker, the preset voltage needs to be applied to the firecracker, then explosion happens, in comparison with a firecracker with dynamite in the prior art, on one hand, storing and transporting are facilitated, the firecracker is not influenced easily by outside environment, and the potential safety hazard is small; on the other hand, the fuel unit is a dynamite-free unit, after explosion, emission ofa large quantity of gas such as sulfur dioxide and sulfur monoxide is avoided, and environmental pollution is avoided. Explosion only occurs after the voltage needs to applied to each firecracker, the chain reaction does not occur easily, energy generated by explosion is controllable relatively, and the potential safety hazard can be further reduced. The invention further provides a firecracker structure.

Description

technical field [0001] The invention relates to the technical field of firecrackers, in particular to a gunpowder-free firecracker and a firecracker structure. Background technique [0002] Firecrackers are a symbol of auspiciousness. During festive seasons or festive days, the sound of firecrackers is loud and colorful, and colorful sparks fly all over the sky, bringing joy and encouragement to people. However, due to the fact that traditional firecrackers are set off by gunpowder, relatively strong smoke and expansion gas with pungent smell will be produced when setting off, which is easy to pollute the environment and also has potential safety hazards. Contents of the invention [0003] Based on this, it is necessary to provide a firecracker and a firecracker structure that can improve the above-mentioned problems in view of the problems that traditional firecrackers are easy to pollute the environment and have potential safety hazards. [0004] A firecracker comprisin...
