Abstract

An air firecracker is formed by parallelly connecting a plurality of air cannons on an air pipe, an air tap is arranged at one end of the air pipe, a one-way valve is arranged in the air tap, a safety valve is arranged at the other end of the air pipe, and an air escape cock is further arranged on the air pipe. Each air cannon is formed by connecting a fixing seat with a sealing sleeve through a connecting column, a slide sleeve is arranged on each sealing sleeve, a stopper is arranged below each slide sleeve, an internal space of each sealing sleeve is divided into an upper air chamber and a lower air chamber, each connecting column is of a hollow structure, an air vent hole is arranged at the position of each upper air chamber, a damping hole is arranged at the position of each lower air chamber, and an explosion opening is arranged at the tail end of the lower air chamber of each sealing sleeve. Sounds similar to those of firecrackers are made by the aid of pressure difference of air, the air firecracker is similar to an explosive firecracker acoustically and visually, environmental pollution and fire can be avoided while personnel risks cannot be caused as air is produced during explosion, a reel of air firecrackers can be recycled for many times, and energy saving, environmental protection and safety are really achieved.
