Embodiment Construction
[0015] Referring to the accompanying drawings, which reflect a specific structure of the present invention, the fireworks inner cylinder with wake and flute effects includes a molded plastic cylinder 2, a number of grooves 9 are evenly distributed on the inner wall of the cylinder 2, and the cylinder The thickness of the wall of the body 2 is 1 mm, and the depth of the groove 9 is 0.5 mm. The groove 9 is weaker than other tube walls, and the cylinder body 2 splits along the groove 9 under the action of internal high pressure during the explosion. Each groove 9 equally divides the circumferential surface of the side wall of the cylinder body 2 so that the bursting uniformity is higher. The flower pattern of the combined fireworks discharge is beautiful, the sound is clear and crisp, and the use effect is better than that of the paper inner cylinder. Moreover, as a plastic product, its inner wall is too smooth. Whether it is using anchoring agent, soil or glue sawdust, it is of...

The invention discloses an inner barrel of a firework with trail and sibilant rale effects. The inner barrel comprises a compression molded plastic barrel body. The top end port of the barrel body isopened, the bottom end port of the barrel body is a closed end integrally formed with the barrel body, a sibilant rale pipe integrally formed with the barrel body is arranged at the center of the closed end, the lower end port of the sibilant rale is opened, the side walls of the periphery of the lower end port of the sibilant rale pipe are connected to the closed end of the barrel body, the upperport end of the sibilant rale pipe communicates to a flash pipe, and a gunpowder leakage gap is formed in the side wall of the flash pipe. The trail and sibilant rale effects are achieved safely andreliably, and other effective agents filled in an inner cavity of the barrel body are ignited. Meanwhile, the production efficiency is improved greatly, the production cost is lowered, the potential safety hazards are avoided, a finished product is standard and normalized and is suitable for mechanical production, and the dampproof performance of a combined firework is improved greatly. Meanwhile,a tedious coiling step of the inner barrel is avoided and the steps of bundling and airing the barrel are cancelled. The firework is no longer affected by climates, and the firework can work in all weather.
Description
technical field [0001] The invention relates to a firework effect inner cylinder, in particular to an inner cylinder with wake and flute effects. Background technique [0002] There are many fireworks with wake and flute effects, such as flute sound thunder, peony thunder, call peony thunder, chrysanthemum thunder, call chrysanthemum thunder, call golden willow, call red flash and so on. In the prior art, the inner tubes of such products are all made of paper cylinders. In the production, it is necessary to press the flute agent in a small tube; then put the small tube into the paper cylinder, and fix the small tube at the bottom port of the paper cylinder when building the mud bottom. After being ignited, the flute agent in the small tube will produce a flame trail and whistling flute effect when it is sprayed backward. [0003] The above-mentioned production process is cumbersome and requires a lot of labor, so it is difficult to realize mechanized automatic production; ...
