Environmentally friendly imitation firecrackers

Abstract

The invention discloses an environment-friendly profiling firecracker. The environment-friendly profiling firecracker comprises a mold cake (1), an outer box (2) and a cover (8), the outer box (2) is used for packaging the mold cake, the mold cake is provided with a spiral groove (7), bubble bags (4) are arranged in the spiral groove successively and continuously, the mold cake is provided with a rotating rod (3), a spring mechanism (5) connected with the rotating rod is arranged in the middle of the mold cake, and the cover is provided with a safety bolt (6) capable of limiting rotation of the rotating rod; a concave-convex face (20) having the same motion direction as the spiral groove is arranged on the inner side face of the spiral groove, a sliding sleeve (13) is arranged at one end of the rotating rod, the sliding sleeve is connected with a backing wheel (15) through a cantilever (14), the backing wheel (15) can be attached to the outer side face of the spiral groove, the sliding sleeve is provided with a lifting rod (19) capable of moving vertically, the lower end of the lifting rod is connected with a pricking needle (17), and the concave-convex face is provided with a guide wheel (21). The environment-friendly profiling firecracker does not pollute the environment, can save resources, cannot cause safety accidents and can achieve the effect of simulating firecracker setting-off.

Description

technical field [0001] The invention relates to a firecracker, in particular to an environment-friendly imitation firecracker which has the effect of setting off the firecracker and does not cause environmental pollution. Background technique [0002] During festivals and holidays, most people like to celebrate by setting off firecrackers, but the production and setting off of firecrackers will not only cause safety accidents and environmental pollution, but also consume a lot of land and timber resources, so the state has made many regulations and restrictions on the production of firecrackers In some big cities, the local governments have accordingly banned the setting off of firecrackers outside the specified time and place, and in some areas (such as high-rise buildings, stations, squares, schools, hospitals, conference venues, institutions and other important places) it is even prohibited to set off firecrackers around the clock. firecracker.

[0002] During festivals and holidays, most people like to celebrate by setting off firecrackers, but the production and setting off of firecrackers will not only cause safety accidents and environmental pollution, but also consume a lot of land and timber resources, so the state has made many regulations and restrictions on the production of firecrackers In some big cities, the local governments have accordingly banned the setting off of firecrackers outside the specified time and place, and in some areas (such as high-rise buildings, stations, squares, schools, hospitals, conference venues, institutions and other important places) it is even prohibited to set off firecrackers around the clock. firecracker

For this reason, people have invented electronic firecrackers to serve as the purpose of setting off firecrackers on festivals and holidays, but the on-site effect of electronic firecrackers is not very good, and the appeal of festive joy is small, so the use has greater limitations.
