A circuit structure of sound and light simulation electric firecrackers

Abstract

The invention discloses a circuit structure of sound and light simulation electric firecrackers, which comprises a circuit for generating electric sparks and explosion sounds and a non-contact switch. A circuit that generates electric sparks and explosion sounds; the circuit that generates electric sparks and explosion sounds is connected to the power supply under the action of the non-contact switch; a control circuit; wherein, the circuit that generates electric sparks and explosion sounds After being connected to the power supply, the circuit for generating electric sparks and explosion sounds generates corresponding sounds and lights under the action of the control circuit. The circuit for generating electric sparks and explosion sounds includes a frying head assembly, a The voltage doubler rectifier circuit for charging the head assembly and the ignition circuit for triggering the energy release of the fried head assembly, the operation of the ignition circuit is controlled by the control circuit. The invention has the advantages of being safe and reliable, having very similar sound and light effects to traditional firecrackers, and high degree of simulation.

Description

technical field [0001] The invention relates to the technical field of electric firecrackers, in particular to a circuit structure for acousto-optic simulation electric firecrackers. Background technique [0002] During festivals and celebrations, people often set off fireworks and firecrackers to create a lively atmosphere, followed by its potential safety hazards. Accidents caused by setting off fireworks and firecrackers occur frequently every year. [0003] Because setting off firecrackers can cause a lot of pollution to the environment, every year around the Spring Festival when the sky is full of firecrackers, the air quality is also seriously reduced. Therefore, the state has issued a policy of prohibiting setting off fireworks, which has improved the air quality. Traditional firecrackers It will also be gradually replaced by other forms of firecrackers; and the emergence of electric firecrackers can just alleviate this problem. [0004] Electric firecrackers are dev...

Problems solved by technology

Also because of its special working principle, it can ionize the surrounding air, thereby producing a large amount of negative ions that clean the air, which is good for your health. It can be said to be a green and environmentally friendly product. Currently, the electric firecrackers on the market only have simple sound and light effects. The atmosphere of firecrackers, at the same time complicated with oxygen cylinders and liquefied gas tanks, similar to salute vehicles, has the problems of complex structure, high price and cost, and inconvenient use
