Description

Technical Field

[0001] The utility model belongs to the technical field of fireworks manufacturing, in particular to an hourglass-shaped fireworks device structure mainly used for assembling cracker fireworks. Background Art

[0002] Currently, the carriers used for fireworks are typically constructed from traditional paper materials, forming a shell or tube. With the development of society and technological advancements, fireworks carriers have significantly improved. For example, various fireworks carriers are molded from paper pulp or bamboo fiber slurry, or injection-molded from plastic materials. Their external shapes are mostly square, circular, conical, fan-shaped, or cylindrical. Small toy fireworks, on the other hand, often feature carriers shaped like guns, knives, swords, or animals. However, these carriers suffer from relatively generic designs, lack distinct symbolic features, and lack personalized themes. While carriers for small toy products can be highly personalized, they often feature stimulating or offensive features, which are detrimental to the physical and mental health of young people. Therefore, it is necessary to break away from the traditional design concepts of existing fireworks carriers and urgently develop a new, simple-to-structure, distinctive, and contemporary-feeling fireworks carrier structure with a streamlined design and manufacturing process. Utility Model Content

[0003] The purpose of this utility model is to provide a new generation of fireworks devices with a unique and elegant design, simple structure, easy assembly, and safe use. This fireworks device is primarily used for pulling fireworks, and can also be used for assembling and setting off jet-type fireworks, effectively resolving the problems raised in the above-mentioned background art. To achieve this purpose, this utility model achieves this through the following technical solutions:

[0004] A fireworks device structure with an hourglass configuration, mainly used for assembling and setting off firecracker fireworks, includes an ignition and explosion device and a firecracker pull line. Its special feature is that the fireworks device structure consists of an hourglass-shaped structure with two upper and lower conical cylinders with two-way tapered openings connected to each other as an integral whole. It includes a lower conical cylinder A and an upper conical cylinder B. The inner cavity of the conical opening of the lower conical cylinder A and the upper conical cylinder B is provided with a central partition plate, and a central perforation is provided on the central partition plate. An ignition and explosion device is installed above the central perforation. An effect body support partition for assembling and placing a fireworks effect assembly is also connected to the middle of the inner cavity of the upper conical cylinder B.

[0005] Furthermore, in one of the above-mentioned technical solutions, the open inner cavity at the upper part of the upper conical cylinder B is provided with an effect object chamber, and a cover plate slot is provided on the inner edge wall of the upper end of the upper conical cylinder B. After the fireworks effect object assembly is loaded into the effect object chamber, a sealing top cover is covered and embedded in the cover plate slot to connect and fix the seal.

[0006] Furthermore, in one of the above-mentioned technical solutions, a fireworks effect assembly is placed above the effect body supporting partition in the inner cavity of the upper conical cylinder B. The fireworks effect assembly is configured as a mixed effect body of cracker-type fireworks, or a jet-type fireworks effect body, or a spray-type fireworks effect body, or a fireworks effect body that can be suitable for assembly in an hourglass carrier for safe ignition.

[0007] Furthermore, in one of the above technical solutions, the central eyelet can be used to insert a cracker cable when configuring a cracker firework, and can be used to insert an ignition fuse when configuring other firework effect bodies.

[0008] Furthermore, in one of the above technical solutions, the lower conical cylinder A and the upper conical cylinder B are two cylindrical cone structures or triangular cone structures or quadrilateral cone structures or pentagonal cone structures or hexagonal cone structures of the same size and shape.

[0009] Furthermore, in one of the above technical solutions, the upper conical cylinder B may be smaller than the lower conical cylinder A, but its lower cone opening should match the size of the upper cone opening of the lower conical cylinder.

[0010] Beneficial effects

[0011] The advantages and beneficial effects of the utility model are:

[0012] 1. The technical solution of the present invention has a simple structure, is easy to process, and is convenient to assemble. When the fireworks are set off, the gas storage space after the ignition and explosion of the ignition and explosion device is large, and there is sufficient energy to impact the effect body support partition upward and move it upward quickly, so that the fireworks effect object assembly installed in the effect object chamber on the upper part of the upper conical cylinder B pushes open the sealing top cover plate stuck in the launching port of the upper conical cylinder B, so that the fireworks effect object assembly is ejected. When the effect object assembly is configured as a cracker firework, it ejects colorful strips, colorful flowers, colorful pieces, colorful stars or other colorful mascots with rich meanings. When the effect object assembly is configured as other fireworks, it can eject various colorful flower shapes and patterns.

[0013] 2. Due to the technical solution of the present invention, the carrier structure of the fireworks is an hourglass-shaped structure. Since ancient times, hourglass objects have symbolized the happiness of love and friendship. Therefore, fireworks products in the shape of an hourglass can be given as gifts to friends or young people when they are courting. This is a more elegant gift, and it expresses the hope that loved ones will always be happy with each other and that their feelings will not disappear with the passage of time. At the same time, it also allows people to recall the sweet times of past relationships. When reminiscing about their loved ones, the beautiful memories of the past will remain in their hearts forever like an hourglass. BRIEF DESCRIPTION OF THE DRAWINGS
