Description

Technical Field

[0001] This utility model belongs to the field of fireworks, specifically relating to a colored smoke firecracker. Background Technology

[0002] Firecrackers, as a traditional form of entertainment and celebration, are widely used in festive activities. Traditional firecrackers add to the festive atmosphere through their explosive sounds and visual effects.

[0003] The sound of traditional firecrackers typically relies on ignition powder, which often contains heavy metals or highly toxic chemicals. These components release substances harmful to the air, soil, and human health during combustion, causing environmental pollution. Furthermore, the high sensitivity of the ignition powder poses significant safety hazards, making accidents prone to occur during production, transportation, and use.

[0004] Furthermore, traditional firecrackers primarily rely on flashes and simple explosions for visual effects, resulting in a lack of innovation and appeal. With the diversification of user needs and the increasing demands for entertainment experiences, single-function firecrackers are no longer sufficient to meet the needs of modern consumers.

[0005] In recent years, colored smoke firecrackers have gradually gained popularity, releasing colorful smoke during their ignition and enhancing the visual appeal. However, current colored smoke firecrackers on the market still have some design shortcomings. Taking a colored smoke firecracker with Chinese patent CN204694166U as an example, it only produces smoke and cannot make a sound. Moreover, its smoke release range is limited, the dynamic visual effect is relatively weak, and it fails to effectively combine multiple entertainment effects, making it difficult to comprehensively improve the user experience.

[0027] As attached Figure 1 -Appendix Figure 2 As shown, this utility model provides a colored smoke firecracker, including a firecracker unit 1, wherein the firecracker unit 1 includes a shell 12, smoke powder 14, explosive beads 15 and fuse 11;

[0028] The outer casing 12 has an inner cavity 121 and an opening 122. The smoke powder 14 and explosive beads 15 fill the inner cavity 121, and the lead wire 11 is introduced into the inner cavity 121 through the opening 122. After the lead wire 11 is ignited, it will ignite the smoke powder 14 and explosive beads 15 sequentially or simultaneously, or the lead wire 11 will ignite one of the smoke powder 14 or explosive beads 15, and one of the smoke powder 14 or explosive beads 15 will then ignite the remaining one. The smoke powder 14 will release smoke from the opening 122, and some of the explosive beads 15 will explode inside the inner cavity 121. After the explosion, the remaining smoke and unexploded explosive beads 15 will be blown out of the opening 122, leaving some unexploded explosive beads 15 outside the opening 122.

[0029] In this invention, the smoke powder 14 allows the explosion of the firecracker unit 1 to produce single-color or multi-color smoke, thereby enhancing the visual effect of the explosion. The exploding beads 15, on the one hand, create a sound, thus providing the sonic atmosphere of the firecracker; on the other hand, they help to expand the smoke powder 14 to a wider area, increasing its coverage and further enhancing its visual effect. Furthermore, as the exploding beads 15 fly out from the opening 122, they carry or propel some of the smoke powder 14, ultimately exploding and creating multi-layered dynamic visual effects, such as meteor trails and smoke diffusion, which are more attractive to viewers. In addition, this invention uses popping beads 15 instead of conventional sound-generating agents (such as those composed of potassium perchlorate, silver powder, sulfur, and rock powder) to generate the sound. On the one hand, this avoids the heavy metal components and highly toxic chemicals commonly found in sound-generating agents, reducing pollution to the air and soil. On the other hand, popping beads 15 have low sensitivity and high safety. Furthermore, they produce less smoke, which does not affect the smoke effect of the smoke powder 14. Moreover, they have less irritating odor compared to sound-generating agents.

[0030] The colored smoke firecrackers provided by this utility model are safer and have less irritating odor compared to conventional firecrackers. They combine smoke, sound and meteor effects into one, making them more interesting and entertaining than traditional single-function firecrackers and meeting diverse needs.

[0031] In one embodiment, the popping bead 15 is a popping rattle bead and / or a popping bright bead. The popping rattle bead consists of a core and a middle package. The core is mainly composed of copper, alloy, bismuth oxide and rice flour. The middle package is mainly composed of potassium nitrate, high potassium, sulfur, pine charcoal, resin, alloy and white rice flour. This is existing technology, and the specific components are not described here. The popping rattle bead produces a loud sound. The popping bright bead is mainly formed by adding sponge titanium or yellow titanium to the core or middle package of the popping rattle bead. This is existing technology, and the specific components are not described here. It can produce light while producing sound, and thus provide a richer visual experience when combined with smoke.

[0032] This firecracker unit 1 can contain only exploding sound beads, or only exploding bright beads, or a certain ratio of exploding bright beads and exploding sound beads.

[0033] In one embodiment, the smoke powder 14 is monochromatic, such as red, green, or yellow, so that when the colored smoke firecracker explodes, it will only release monochromatic smoke. The smoke powder 14 is mainly composed of potassium chlorate, sulfur, environmentally friendly smoke red, and flour, which is existing technology, and the specific components will not be described in detail here.

[0034] In one embodiment, the smoke powder 14 has multiple colors. In this case, the smoke powder 14 of different colors can be arranged in layers in the inner cavity 121, for example, red, green and yellow are arranged in sequence. When the colored smoke firecracker explodes, red, green and yellow smoke will be released in sequence to further enrich the visual experience.

[0035] In one embodiment, the outer shell 12 is made of paper. This reduces cost and weight, and paper is a biodegradable material, so the residue after combustion decomposes easily, resulting in less environmental pollution. Moreover, compared to plastic or metal shells, paper shells do not produce hard fragments when they explode, causing less harm to people in the vicinity.

[0036] In one embodiment, the bottom of the inner cavity 121 of the outer shell 12 is sealed with a bottom loess layer 13. Loess is used as the bottom of the inner cavity 121. Loess has high fire resistance and can play a role in heat insulation and fire prevention when the firecracker is not lit or accidentally comes into contact with a fire source, reducing the risk of explosion. At the same time, the bottom loess layer reinforces the structure of the firecracker outer shell 12, making it less prone to deformation or damage during storage and transportation. In addition, loess is low in cost and can prevent moisture and seal.

[0037] In one embodiment, an open loess seal layer 16 is provided at the opening 122 of the outer shell 12, and the lead wire 11 passes through the open loess seal layer 16. Providing an open loess seal layer 16 at the opening 122 of the firecracker not only improves the sealing performance and the ignition effect, but also has significant safety and environmental advantages.

[0038] In one embodiment, the smoke powder 14 and the bursting beads 15 are mixed and arranged. In this embodiment, the smoke and bursting effects occur simultaneously, ensuring both the bursting effect of the bursting beads 15 and the diffusion effect of the smoke.

[0039] In one embodiment, the smoke powder 14 and the bursting beads 15 are arranged in layers, with the smoke powder 14 arranged on the side close to the opening 122. In this embodiment, the smoke is released from the opening 122 first, and the bursting beads 15 begin to burst when the smoke release is about to end, thereby bursting and diffusing the smoke concentrated from the opening 122, thus improving the diffusion effect of the smoke.

[0040] Reference Appendix Figure 3 In one embodiment, the colored smoke firecracker also includes a main fuse 2, on which a plurality of firecracker units 1 are connected in series to achieve sequential ignition of the plurality of firecracker units 1.

[0041] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
