Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display shells, in particular to a display shell. Background Art
[0002] In modern fireworks technology, the sphere of a firework shell is usually composed of two hemispheres; the hemisphere shell is filled with spherical particles made of a mixture of oxidants, combustibles, effect raw materials, and adhesives, referred to as bright beads; the aesthetic effects produced during the fireworks are all produced by the combustion of bright beads. During the fireworks, the combustibles burn with the help of the oxidants to make the effect fuel emit light, color, and shape effects.
[0003] During use, the existing display shells are generally composed of an upper shell and a lower shell, wherein a firing material is arranged inside the lower shell, and the upper shell and the lower shell are generally combined and connected by a socket connection. During transportation, when the display shells are squeezed against each other, the upper shell and the lower shell are easily separated, causing the internal firing material to leak and cause pollution. Therefore, we have introduced a new display shell. Utility Model Content
