Description

Electronic firework spraying device

Technical field

This application relates to simulated fireworks, and in particular to an electronic firework spraying device.

Background technique

The traditional fireworks made with gunpowder potions, after being ignited, the gunpowder blasts and breaks through the shell of the paper tube to achieve the effect of sound, firework and red on the ground. When the fireworks are set off, the burning point of the gunpowder is between 800 degrees and 1200 degrees, which is not only easy to burn people, but also requires the setting off in a fireproof environment, otherwise it is easy to catch fire. When the fireworks are set off, a lot of dense smoke will be emitted, which is very serious to the environment. In addition, dangerous injuries are easily caused during production, processing and transportation.

The current market has a cold firework that replaces traditional gunpowder fireworks. It is made of metal powder with a low ignition point. Its ignition temperature is low, and the ignition point is between 60 degrees and 80 degrees. This kind of cold firework has poor visual effect, and it still needs to be ignited by an open flame when it is set off. Therefore, it still needs to be set off in a fireproof environment. In addition, if the burning temperature of cold fireworks is as high as 600 degrees during the discharge process, it will also be dangerous to environmental safety and personal safety. And the use environment of cold fireworks should pay attention to avoid the chemical reaction of other gases in the air. When the chemical reaction is 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 are prone to occur. Even exploded.
