Description

A kind of simulation electronic firecracker

Technical field

This application relates to firecrackers, in particular to a simulated electronic firecracker.

Background technique

Setting off firecrackers to celebrate the festival is a traditional custom of the Chinese nation for thousands of years, and it is also a favorite item of many people in the world. The traditional firecrackers made of gunpowder medicament, after being ignited, the gunpowder blasts and breaks through the shell of the paper tube to achieve the effect of sound, fireworks and red on the floor. When firecrackers are set off, the ignition point of the gunpowder is between 800 degrees and 1200 degrees. Not only is it easy to burn people, but it is also required to be set off in a fireproof environment, otherwise it is easy to catch fire. When firecrackers are set off, they emit a lot of dense smoke, which is very serious to the environment. In addition, dangerous injuries are easily caused during production, processing and transportation. Therefore, in recent years, many countries in China and around the world have begun to strictly restrict the firing of firecrackers in major cities and regions.

The existing simulated firecrackers include decorative electronic firecrackers. The decorative electronic firecrackers are a set of firecracker shells with sounds and lights installed inside. When the switch is turned on, the firecrackers keep beating, and the lights keep flickering, which has no effect on human vision. The market acceptance of any firecrackers is very low.
