Moreover, gunpowder in the traditional fireworks can release a large amount of toxic gases such as sulfur dioxide, sulfur monoxide, nitrogen dioxide, nitrogen monoxide and the like in the process of firing, and a large amount of carbon black dust can be released due to incomplete combustion of charcoal. The setting off of fireworks can cause serious air pollution problems. The safe and environment-friendly firework of the utility model has very simple and safe components, and the product after being set off is magnesium oxide, thus not generating any product harmful to human body.
In addition, when traditional fireworks are set off, the gunpowder combustion explosion can produce huge sound, and can have strong noise interference to the residents around. After the gas is completely set off, a large amount of paper scraps and garbage are generated, and the cleaning work is very heavy. The environment-friendly safe firework has small sound when being set off and small interference to surrounding residents; and a large amount of paper scraps and garbage can not be generated, and the problem of secondary pollution of the traditional fireworks to the surrounding environment is solved.
Meanwhile, the firework bullet launching device can use energy sources such as fuel gas to replace electric power when generating high temperature, and a gas tank filled with high-pressure gas can be used at high pressure. The fireworks can replace magnesium and magnesium-aluminum alloy with other kinds of metal or alloy such as titanium, and the material which can keep proper strength can be used as a protective layer, wherein the material does not change when contacting air at high temperature, and comprises the following components: pottery clay and glass, which are not described herein.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
