A modular pyrotechnic launch unit includes a launch module, a first module, and a second module. The launch module includes a launch barrel. The first module is coupled in series to the launch module. The first module includes a first ignition state in which the first module ignites a pyrotechnic element that will then pass through the launch barrel. The first module also includes a first pass-through state in which the first module allows a pyrotechnic element ignited by another module to pass through the first module. The second module is coupled in series to the first module. The second module includes a second ignition state in which the second module ignites a pyrotechnic element that will then pass through the first module and through the launch barrel.

A fireworks aerial display shell is provided with multiple casings of cylindrical configuration that are joined together in end-to-end relationship. Each casing defines an interior volume in which an effects charge is packed. A plug is positioned between the effects charges and has an opening through which an ignition source passes to ignite one of the effects charges as a result of burning of another of the effects charges. An outer casing may surround at least parts of the multiple cylindrical casings and includes multiple partially ball-shaped segments.

A compression molded combined firework includes a plurality of tubular cavity bodies evenly distributed in parallel on a body. Upper ends of the tubular cavity bodies are open, lower ends of the tubular cavity bodies are closed. Chemicals for launching fireworks and effect parts are disposed in the tubular cavity bodies. Flash holes penetrating through the bottom surface of the body are formed in the closed ends of the tubular cavity bodies. Bottom surface openings of the flash holes are located in a wiring groove. A blocking groove is disposed in the wiring groove and between the bottom surface openings of the flash holes. The wiring groove is sealed with glue. The glue forms a closed ring shape along the cross section direction of a leading wire in the wiring groove, thereby blocking a channel where powder gas goes forwards along a gap, and eliminating the phenomenon of blaze.

A fireworks aerial display shell is provided with lift charges positioned at opposite ends of a casing that additionally contains an effects charge. Fuses are operatively associated with the lift charges and the effects charge in a manner to ignite the lift charges a period of time before igniting the effects charge. When either one of the ends of the casing is placed facing a closed bottom of a launch tube of a reusable mortar, the burning lift charge at that end of the casing when ignited exerts a propelling force to propel the aerial display shell upwardly out of the launch tube to an intended height before the effects charge is ignited to create a pyrotechnic visual effects display.

The invention relates to a pyrotechnic article (10), comprising at least one first receiving part (11) for a pyrotechnic effect (20) and at least one ignition means (40) connected to the pyrotechnic effect (20). Moreover, at least one auxiliary ignition system (30) is provided, which can be ignited by the ignition means (40), wherein an igniting flame (31) can be generated by the auxiliary ignition system (30), and the igniting flame (31) can, in particular, be directed substantially horizontally out of the pyrotechnic article (10), whereby at least one additional pyrotechnic article comprising a pyrotechnic effect can be ignited.

A Pyro-Cube fireworks includes a plurality of fireworks units. Each of the fireworks units includes a fuse, a plurality of fireworks launching tubes, at least one male tube, and at least one female tube. The fuse connects with the female tube. The male tube and the female tube are configured in a rim of the fireworks units. The fuse connects all fireworks launching tubes with the male tube from the female tube. The female tube of one fireworks unit engages with the male tube of another fireworks unit to connect the fuse of the female tube with the fuse of the male tube of adjacent fireworks unit. Only the fuse on the female tube of the first fireworks unit has to be ignited, and all fireworks units are ignited in a sequence corresponding to the connecting sequence of the fuses. The igniting operation of the fireworks is simple and safe.
