Abstract

The invention provides an air-cracker single piece, which comprises a cracker body, a sliding sleeve and a cracker head; a lower air chamber is formed on the left side of the cracker body which is provided with a mounting post; the sliding sleeve is slidably sleeved on the mounting post; the cracker head is fixed with the mounting post and seals the right opening of the sliding sleeve; an upper air chamber is defined between the sliding sleeve and the cracker head; an air inlet hole is formed on the cracker head; an explosion gap is arranged at the connection of the sliding sleeve and the cracker body; and a reset mechanism is disposed between the sliding sleeve and the cracker head. The air-cracker single piece provided by the invention achieves the advantages of easy resetting, simple structure, safety, environment protection and reusability.

Description

technical field [0001] The invention relates to a firecracker, in particular to a safe and environment-friendly firecracker. 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 causes a waste of resources. Many cities have banned the setting ...
