Abstract

The invention provides an environmentally-friendly air salute. The environmentally-friendly air salute is composed of an overflow valve (1), an air-charging nozzle (2), a pressure gauge (3) and one or more salute launching units. Each launching unit comprises a one-way valve (4), an electromagnetic directional valve (5) and a salute unit body (6); by injecting high-pressure air into airtight cavities of the salute unit bodies and controlling switches to rapidly exhaust air, explosion sounds like salutes and firecrackers can be generated, and the exhausted high-speed airflow can launch fireworks into air. The whole system can basically achieve the functions of traditional gunpowder-type fireworks and crackers. The environmentally-friendly air salute is safe and reliable in performance, achieves zero emission, and is free of pollution, capable of being recycled, economical, environmentally friendly, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an acoustic device and a firework launching device which replaces a traditional gunpowder salute and uses air as a medium. Background technique [0002] The use of fireworks and firecrackers in China has a history of more than 1,000 years. After thousands of years of inheritance, it has become the carrier of traditional culture and folk customs and an indispensable component of festival celebrations in modern society. The main components of fireworks and firecrackers are black gunpowder including sulfur, charcoal powder and potassium nitrate, etc. During the firing process, a large amount of carbon, sulfur, nitrogen oxide harmful gases and metal oxide dust will be produced. The volume of various mixtures in the closed space inside the barrel The rapid expansion forms an instantaneous high pressure, and the bursting of the paper roll causes the barrel to burst, resulting in violent turbulence in the air and an explosion sound. ...
