Firework device with effect tail gunpowder structure on surface of inner cylinder

Abstract

The invention discloses a firework device with an effect tail gunpowder structure on the surface of an inner cylinder. Launching cylinders 1 of a plurality of internal effect inner cylinders 3 are sequentially spliced and adhered to one another on a paper partition plate 13 in a fan arch-shaped at an inclination to form a group of single-row launching bodies; multiple groups of single-row launching bodies are sequentially and longitudinally arranged and adhered to a bottom plate 15; adjacent rows are adhered and fixed to each other to be combined into a whole body through the corresponding paper partition plates 13; a plurality of monomer launching cylinders are connected with one another through a string blasting fuse 14 in a stringing manner; an igniter fuse 11 is led out from a hole ofthe lower end part of a first launching cylinder 1 at the left of the front row of the combined launching body; a cavity below a penetrated mud head 8 of an inner cavity of each effect inner cylinder3 is housed with a tail gunpowder 9; launching nitre 6 and a bright bead 5 are equipped in an cavity above each penetrated mud head 8; the center of the lower part of each effect inner cylinder 3 is provided with a fire passing fuse 7 which penetrates through the tail gunpowder 9 to be communicated with the launching nitre 6; and the bright beads 5 are multiple silver lighting bright beads of a bright spot particle structure. The firework device has the advantages of simple structure, safety and reliability in setting off, unique effect, richness in motion and the like.

Description

Technical field [0001] The invention relates to a firework, in particular to a firework device with an effect tailing structure on the bottom surface of an inner cylinder. Background technique [0002] Combination fireworks is a large-scale firework product developed in recent years. It has a combination of sound, light, color and other effects when it is set off and has a long duration. The scene is atmospheric and lively. It is very important for fireworks evenings and festive festivals. A favorite firework product. At present, although the combination fireworks have a wide variety of colors, the design of the combination structure of the effect, pattern and shape is unreasonable. The main reason is that the product has no continuous dynamic changes and pattern changes during the discharge process, and there is no three-dimensional effect of multi-level changes. , Especially for the bead-spitting products, some only have a single bright spot, but there is no product that can c...

Problems solved by technology

At present, although there are many types of combined fireworks, the design of the combination structure of the effect pattern is unreasonable, mainly because the product does not have continuous dynamic changes and pattern changes during the discharge process, and there is no three-dimensional state effect of multi-level changes. , especially bead-spitting products, there are only single-point bead-spitting beads, and there are no products that can continuously spit beads in the air and have multiple shining points in one bead.
