Technical Field

The invention relates to a display shell.

Background

The effect piece is formed by the process of manufacturing pyrotechnic composition or a single body containing the pyrotechnic composition, and comprises a powder grain, a powder column, a powder block, a powder ball and other bare powder effect pieces; non-naked drug effect components such as drug bag, effect inner barrel and effect lead. The effect lead consists of an outer cladding and firework powder wrapped by the outer cladding, and can be produced by automatic equipment (a lead machine) by adopting the same preparation process as a firework lead (a firing cable for ignition and fire transmission). The finished product of lead machining is rectangular form lead, and the rolling is reserve, cuts into suitable length as required and uses.

The effect lead wire is light in body and has certain self-generated power during combustion, so that the lead wire has longer dead time and is easy to form the effect of floating and falling, and the lead wire is often used for manufacturing the effect of simulating floating and falling in combined firework products, such as the effects of falling leaves, floating flowers, floating snow and the like. As in the patent literature: the bulletin No. CN201311243Y discloses a colorful fallen leaves model combined firework; the bulletin No. CN201311242Y discloses a safflower fallen leaf special-shaped combined firework; "snowing flying fireworks" disclosed in bulletin No. CN 201575755U; "Piaoju fireworks" disclosed in bulletin No. CN200944023Y, etc.
