Embodiment Construction

[0009] Such as figure 1 Shown, a kind of air firecracker is made up of being connected with a plurality of air cannons 2 on a trachea 1, is provided with an air nozzle 3 at one end of the trachea 1, and is provided with a one-way valve 31 in the air nozzle 3, in The other end of the trachea 1 is provided with a safety valve 4, and a deflation switch 5 is also provided on the trachea.

[0010] The air cannon 2 is composed of a fixed seat 21 and a sealing sleeve 22 connected by a connecting column 23, a sliding sleeve 24 is arranged on the sealing sleeve 22, and a stopper 25 is arranged under the sliding sleeve 24, so that the inner space of the sealing sleeve 22 is divided into There are two upper and lower air chambers, the connecting column 23 is a hollow structure, a vent hole 27 is opened at the upper air chamber 26, a damping hole 29 is opened at the lower air chamber 28, and at the end of the lower air chamber 28 of the sealing sleeve 22 is a Explosion port 30.

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.

Description

technical field [0001] The invention relates to a sound device replacing traditional gunpowder firecrackers. Background technique [0002] In order to cope with the solemn, solemn and lively atmosphere, setting off firecrackers has become an indispensable task. At present, most of the traditional explosive firecrackers on the market not only pollute the environment, but also are dangerous. A large number of explosives are piled up during production. Once the explosion causes great harm, it will not only seriously pollute the environment when it is set off, but may also injure people and cause fires. Because traditional firecrackers are disposable consumables and cannot be reused, it also causes fire hazards. A waste of resources, many cities have banned the setting off of explosives and firecrackers. Contents of the invention [0003] The purpose of the present invention is to solve the defects in the above-mentioned technology, and provide a kind of air firecracker with ...
