Abstract

An ultrasonic wave firecracker safe burner comprises a signal emitter and a firecracker fuse burner. The signal emitter is formed by an ultrasonic signal generator and an emission antenna. The firecracker fuse burner is formed by two steps of receiving antennas, two steps of signal amplifiers, two open delay relays, a safe bolt, an instructing lamp circuit, and an automatic igniter. With said invention, user can ignite the firecracker remotely, to improve the safety, with simple structure.

Description

(1) Technical field [0001] The invention relates to the field of setting off firecrackers, in particular to an ultrasonic firecracker safety setting device integrating entertainment, safety and practicability. (2) Background technology [0002] With the improvement of living standards, people's requirements for leisure and entertainment are getting higher and higher. At the same time, the safety of entertainment facilities and equipment has also received more and more attention and attention. On festive days, especially our Chinese traditional Spring Festival, firecrackers are essential. However, accidents caused by setting off firecrackers emerge in endlessly every year. In view of safety issues, electronic timing firecrackers have appeared on the market, which indeed reduces the danger of setting off firecrackers, but at the same time greatly reduces the fun and festive atmosphere when setting off firecrackers. [0003] To the method that safety setting off firecracker p...
