Combined firework without ejecting powder

Abstract

The invention discloses a combined firework without ejecting powder. The combined firework is characterized by comprising bottom plugs and effect cylinder bodies, wherein the bottom plugs are arrangedat the bottoms of inner cavities of the effect cylinder bodies, fire blasting mud heads are arranged at the upper end parts of the effect cylinder bodies; fire spraying ports are formed in the centers of the fire blasting mud heads, effect bright beads are arranged in cavities between the bottom plugs of the inner cavities of the effect cylinder bodies and the fire blasting mud heads, ignition devices are arranged in the effect bright beads in a penetrating mode from the centers of the fire spraying ports, so that an internal self-ejecting function of a powder structure can be formed throughthe effect bright beads, and a fountain ejecting effect without powder can be achieved; and the bottom plugs are of wood plug structures or mud head structures or dry powder structures, and the ignition devices are leads or electric ignition head devices, the combined fountain ejecting is a combined fountain ejecting body with a free-ejecting-powder structure, and the combined fountain ejecting body is composed of the plurality of effect cylinder bodies arranged in an outer cylinder, and the outer shape of the combined fountain ejecting body is in a circular shape or a suitable geometrical shape. According to the combined firework, the powder composition is simple in structure, and combined assembly is simple and convenient; and the combined firework is capable of meeting the requirementsof new setting-off quality standards of low carbon, safe, environment-friendly and green fountain ejecting.

Description

technical field [0001] The invention belongs to the technical field of fireworks, in particular to a combined fireworks without spraying medicine. Background technique [0002] The existing flower-spraying fireworks products all burn the effect bright beads / effect powder placed on it through the spray powder / propellant located at the lower part of the effect cylinder cavity and spray them out of the cylinder mouth to produce the spray pattern effect. A kind of firework fireworks with propellant and effect bright beads / effect drug structure, its jet strength is big, and jet height is high, but this kind of fireworks firework with propellant structure is only suitable for the professional setting off of square open area or fireworks show, and the family Party or stage discharges require low-carbon and environmentally friendly spray fireworks with low spray intensity, appropriate spray height, and long spray time. Therefore, it is necessary to develop a combination of firework...
