摘要:
A fireworks kit can have a set of fireworks having multiple fireworks of different types and a plurality of detonators in communication with the fireworks that are configured to launch or detonate a firework attached thereto. A remote controller or mobile device can be in communication with the detonators and operable to provide dynamic or user customizable control of detonation, launching, or ignition of the fireworks.

The present invention relates to a combined fireworks with launching pits and multi-channel fireproof structures comprising a body, several tubular cavities are uniformly arranged on the body with the upper ports thereof are open and the lower ports thereof are closed, inner cylinders of fireworks and propellants are arranged inside the tubular cavity, the bottom of each tubular cavity is provided with annular grooves and launching pits. The bottom surface of the body is provided with several fireproof bosses, the position of each fireproof boss corresponds to each tubular cavity in the body respectively, and recessed countersinks are arranged on the fireproof bosses, the priming holes are arranged within the recessed countersinks, one end opening of the priming hole is located on the bottom surface of the launching pit, and the other end opening of the priming hole is located in the recessed countersinks. The present invention solves the problem of directional instability and unfocused acting force of the inner cylinders of fireworks during launching. With multi-channel fireproof structures protruding from the bottom surface, this invention can also prevent crossfire during launching.

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.

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.
摘要:
A combination fireworks device including at least one fire transmission unit including a plurality of single tubes placed in successive arrangement, wherein each of the plurality of single tubes includes a fire hole located on the tube side wall, and a single, continuous fuse connecting the plurality of single tubes to each other in series, wherein a portion of the fuse extends into the fire hole of each of the plurality of single tubes and the portion of the fuse includes a length of the fuse folded back onto itself in each fire hole.

An explosive body is encapsulated in such a way that the encapsulation or casing supports the ignition behavior of the explosive body or of the components. The explosive body has a casing for accommodating the components of the explosive body, which differ with regard to the chemical composition and the properties thereof. An additional component is located in the casing as an ignition aid. The explosive body can be ignited through the top/side surface of the casing or by an internal ignition mixture located inside the explosive body.

A combined firework is disclosed in the invention. In the combined firework, several tubular holes whose central axes are parallel to each other are uniformly distributed in a body, the tubular holes have openings upward and bottom ends closed, the closed end of the bottom of each tubular hole is provided with two small through holes penetrating through the bottom of the body and respectively provided with an inward fuse and an outward fuse in series connection, the body, the tubular holes and the small through holes thereof are an integral structure moulded in one time; on the bottom in the tubular hole propellant powder is provided and connected with the outward fuse and the inward fuse, on the propellant powder an inner cylinder or effect powder is provided. The combined firework using the above solution has standard specification, firm structure and high production efficiency; moreover, the original fuse connection at the side of the cylinder body is changed into the fuse connection at the bottom, and the fuse connecting holes are mechanically moulded with a consistent size of the hole and precisely controlled distance between holes, therefore, the launching time is accurate and safety is good.
