Modeling firework with novel handheld electric ignition rotating structure

Abstract

The invention discloses a modeling firework with a novel handheld electric ignition rotating structure. The modeling firework is characterized by comprising a rotating body, a fire transfer fuse, an igniter, a fire transfer device and a rotating part; the igniter is integrated by an effect cylinder sleeve, a shaft sleeve and a tray, wherein the upper part of the shaft sleeve is perpendicular to aninner cavity in the center position of a center shaft of the effect cylinder sleeve; the effect cylinder sleeve is spaced into left and right cylinder sleeves, and the lower end extends to the external position of the lower bottom surface of the tray through the center of the tray connected to the outer wall of the cylinder sleeve under the effect cylinder sleeve; the fire transfer hole is formedin the front middle position of the shaft sleeve at the upper part of the tray; the effect cylinder sleeve is transversely provided with a long opening corresponding to the fire transfer hole in thefront middle position of the shaft sleeve; and the rotating body is a rotating body with a combined structure by a split effect cylinder with multiple spraying holes at two ends and left and right effect cylinder sleeves on the igniter.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics, and in particular relates to a novel hand-held electrically ignited and self-rotating shaped firework suitable for indoor or outdoor hand-held discharge, which can change the shape effect and is environmentally safe. Background technique [0002] At present, hand-held rotating fireworks are generally ignited and set off manually. The rotating body is a single tube structure, and the hand-held parts are bamboo sticks or wooden poles or thin iron rods. When the drug burns, it produces flames and the reaction force of gas jets to form a moment of rotation around the axis to make the jetted colored flames or sparks form a ring shape, which is generally called "one-character fire wheel" fireworks. "Wheel" fireworks are only suitable for outdoor display; in the prior art, the luminescent rotating firework used for indoor display, the small ones are rotated around hanging wires or hung with iron na...

Problems solved by technology

[0002] At present, hand-held rotating fireworks are generally ignited and set off manually. The rotating body is a single tube structure, and the hand-held parts are bamboo sticks or wooden poles or thin iron rods. When the drug burns, it produces flames and the reaction force of gas jets to form a moment of rotation around the axis to make the jetted colored flames or sparks form a ring shape, which is generally called "one-character fire wheel" fireworks. "Wheel" fireworks are only suitable for outdoor display; in the prior art, the luminescent rotating firework used for indoor display, the small ones are rotated around hanging wires or hung with iron nails, the large ones are rotated by wheels with bushings, and the small ones are rotated Fireworks are ignited by artificial ignition, and large fireworks are ignited by electric ignition. Especially when small-scale fireworks are set off on indoor stages, hand-held rotating fireworks still use manual ignition, which is extremely inconvenient and unsafe to set off. At present, there is no live fire on the market.
