Description

Electronic firework jet control device and electronic firework jet system Technical field

This application relates to simulated fireworks, in particular to an electronic firework spray control device and an electronic firework spray system.

Background technique

Setting off fireworks to celebrate festivals is a traditional custom of the Chinese nation for thousands of years, and it is also loved by many people around the world.

There are two types of fireworks in the current market. One is the traditional gunpowder fireworks, also known as fireworks. After being ignited, the fireworks emit various colors and the ignition point is between 800 degrees and 1200 degrees. The advantage is that the visual effect of flame burning is good. The disadvantage is that the setting off environment requires a fireproof environment, otherwise it is easy to catch fire and emit a lot of dense smoke after burning, which is very serious to environmental pollution, and the high temperature of combustion can easily cause harm to the human body. At the same time, it is also prone to dangers during production, processing and transportation. The other is cold fireworks, which are made of metal powder with a lower ignition point. The ignition point is between 60 and 80 degrees. The advantage of cold fireworks is that the ignition temperature is low, but the disadvantage is that the visual effect is poor. At the same time, cold fireworks still need to be ignited by fire. , The setting environment still requires a fireproof environment. In addition, if the cold firework is burned during the setting off, the combustion temperature can reach a high temperature of 600 degrees, which will also cause dangerous damage to environmental safety and personal safety. The use environment of cold fireworks should be careful to avoid chemical reactions with other gases in the air. When the chemical reactions are serious, there is even an explosion hazard. For example, if you use entertainment products such as colored foam sprays in the environment of setting off cold fireworks, chemical reactions or even explosion.
