Description

Technical Field

[0001] This utility model belongs to the field of firework and toy manufacturing technology, specifically relating to a firework with an improved structure. Background Technology

[0002] In existing technology, there are two types of firework displays. One type is a firework display with a high-pressure gas reservoir. This type controls the launch of the firework through the high-pressure gas reservoir at the bottom of the tube. This type is only suitable for adults to use in celebratory occasions. Although it produces a spectacular display, the high-pressure gas reservoir poses a safety hazard and is very loud. The other type is a small pull-string firework display containing gunpowder. This small pull-string firework has a small amount of explosive charge, and children can launch and release colorful strips or flakes simply by holding the tube with one hand and pulling the rope with the other. While both types of firework displays are smokeless and gunpowder-free, making them environmentally friendly, their drawbacks are: the former is unsuitable for children and poses a safety hazard when ignited; the latter, due to its miniaturized design, has a small amount of explosive charge, and the small tube makes it unstable when held by fingers, easily falling off and affecting the ignition effect. Therefore, it is necessary to innovate and develop a new type of firework that falls between the aforementioned fireworks and small pull-string firework, so that it can be held and lit stably, produce a large quantity of effect objects, have a variety of colors and varieties, have rich visual effects, and strong symbolic characteristics, making it suitable for adults and children to play with and set off. Utility Model Content

[0003] In view of the many problems existing in the above background, the purpose of this utility model is to provide a firework with an improved structure that is fashionable, simple and clear in design, grand in appearance, convenient and stable to hold when lit, safe and reliable, and has a large space volume in the tube and effect section.

[0004] To achieve the objectives of this utility model, the technical solution adopted is as follows:

[0005] An improved firework display includes a firework effect section, a firework mixing effect object, a bottom support plate for the effect object, a top cover plate for the effect section, a banging device, and a pull rope. It is characterized by further including a tube section that is assembled and connected with the firework effect section and also serves as a handle, and a boss edge extending outwards from the top of the firework effect section along the outer edge of the tube opening. The bottom arc surface of the boss edge covers and fits tightly against the upper end face of the tube section, forming a columnar structure for the firework display device.

[0006] In the implementation of the above technical solution, the latte art effect section is further composed of two parts: the upper part is processed into a hollow cylindrical short-section tubular structure, the cavity of which includes a latte art effect object compartment for accommodating and storing the latte art effect object; a bottom tray for the effect object is placed under the bottom of the latte art effect object; and an effect section top cover plate covers the latte art effect object. The effect section top cover plate is fitted and positioned in a cover plate slot on the inner circular wall of the upper port of the latte art effect section. In this embodiment, the panel of the effect section top cover plate can be printed with patterns or text that match the product, or different colored paper can be glued to the panel. The lower half of the decorative effect section is machined into a lower conical cavity structure that matches the upper half. The conical cavity is a gas storage chamber for explosive combustion. A pull rope insertion hole is machined at the center of the bottom of the cone in the gas storage chamber for the pull rope to pass through. The popping device is installed above the pull rope insertion hole and connected perpendicularly to the bottom of the cone. One end of the pull rope is fixedly connected to the bottom surface of the popping device, and the other end extends through the pull rope insertion hole and is led out through the lower port of the inner cavity of the tube to the outer wall of the tube and fixed. Thus, the entire assembly is formed into a single improved structure of the decorative firecracker. When ignited, simply hold the tube with one hand and pull the cord extending from the outside of the tube with the other hand to activate the pyrotechnic device. This causes the device to explode in the pyrotechnic gas storage chamber, generating gas with impact energy that propels the bottom support plate of the effect object upwards. Under the impact force of the gas energy, the bottom support plate of the effect object functions like a piston, pushing the confetti mixed effect object stored above towards the upward outlet, which then opens the top cover of the effect section. The confetti mixed effect object is then ejected towards the top nozzle of the confetti effect section, creating a colorful pyrotechnic effect in the air.

[0007] In the implementation of the above technical solution, the lace effect part is further manufactured using plastic materials or other plasticized materials, and the tube part is made of paper materials to form a hollow tube structure, such as a structure made of firework yellow cardboard rolled into shape, or a structure made of paper fiber pulp, bamboo fiber pulp or plant fiber pulp in one-time molding, or a structure made of plastic material by one-time injection molding or molding. The lace effect part and the tube part are combined into an integral molding structure, or a structure in which one end of the tube is directly connected to the lower end of the short section tube of the upper half of the lace effect part in one-time molding.

[0008] In the implementation of the above technical solution, the latte art effect section is further described as having a circular tube shape or a polygonal geometric tube shape, and the shape of the latte art effect section matches the shape of the tube section.

[0009] In the implementation of the above technical solution, the boss edge is a newly added edge component based on the existing known technology. Its function is to enable the upper end face of the boss edge to stop at the end of the tube and fix it when the lace effect part is fitted into the tube opening of the tube part, so that it no longer extends into the cavity and is recessed in the tube cavity.

[0010] In the implementation of the above technical solution, the mixed effect object is further composed of colored paper flowers, colored paper pieces, colored paper ribbons, colored paper stars or other lightweight materials processed into colored strips, ribbons, colored flowers, colored stars, and geometric colored pieces. It can also be a mixed effect object of various animal colored pieces or miniature toys processed into paper-plastic composite materials, which are integrated into a single structure.

[0011] Effective effect

[0012] The advantages and beneficial effects of this utility model are:

[0013] 1. The technical solution of this utility model has a simple structure and a unique combination configuration. The main part of the garland effect section is fitted into a straight tube at one end and connected to form an integrated structure. The garland effect section is not visible from the outside, and there is only the visual impression of a tube structure. Therefore, the combination structure is novel and the creative design is unique. After pulling the popping device hidden in the tube, it is discovered that strings of colorful strips, flowers, pieces, stars, various geometric colored pieces, miniature toys, small animal cards and other auspicious objects are suddenly sprayed from one end of the tube held by hand, showing colorful auspicious objects floating and flying all over the sky in the air.

[0014] 2. By adopting the technical solution of this utility model, the safety hazards of fireworks and firecrackers are effectively solved, and the defect of poor stability of the handheld tube when setting off firecrackers is also overcome. At the same time, the introduction of a new type of improved firecracker into the market will greatly enhance the competitiveness of the fireworks market, and further prove that the way out for fireworks companies lies in creating and designing more and better new types of fireworks.

[0021] Example

[0022] The structural features of its specific embodiments are as follows:

[0023] Figure 1 , Figure 2 The image shows a preferred embodiment of the present invention. Specifically, in a preferred embodiment, it includes a flower-shaped effect section 2, a popping device 5, and a pull rope 7. Its structural features are: it also includes a tube section 8 that is fitted and connected to the outside of the flower-shaped effect section 2. The top arc-shaped opening edge of the flower-shaped effect section is provided with a boss edge 10 that extends outward along the arc periphery, so that one end fitted on the tube section and the lower arc surface of the boss edge 10 are closely matched and integrally constructed, forming a columnar structure flower-shaped firework device.

[0024] Specifically, in a preferred embodiment, as shown in the figure, the popping device 5, pull rope 7, top cover plate 1, mixed effect object 3, and bottom support plate 4 of the effect object in the lace effect section are all finished components in known technology and are assembled by existing manufacturing processes. In order to meet the needs of innovative modification, the lace effect section is enlarged and lengthened as a whole, and a boss edge 10 with the same thickness as the tube wall of the tube section 8 is extended outward from the arc edge of the top surface. The boss edge 10 is a newly added edge component based on existing known technology. Its function is to enable the upper end face of the lace effect section to stop at the end of the tube section and be fixed when the lace effect section 2 is fitted into one end of the tube section 8, so that it no longer extends into the cavity and is recessed in the tube cavity.

[0025] Specifically, in a preferred embodiment, as shown in the figure, the lace effect part 2 is made of plastic material or other materials, and the tube part 8 is made of paper material to form a hollow cylindrical straight tube structure, such as firework yellow cardboard, paper fiber pulp, bamboo fiber pulp or plant fiber pulp.

[0026] Specifically, in a preferred embodiment, as shown in the figure, the latte art effect section 2 consists of two parts: the upper part is processed into a hollow cylindrical tube structure, and the inner cavity of the upper part includes a cover plate slot 11 for the top cover plate 1 of the effect section to be fitted and connected, a latte art effect material chamber 9 for filling the latte art mixed effect material 3, and a bottom support plate 4 of the effect material is also provided at the bottom of the inner cavity; the lower part of the latte art effect section 2 is processed into a hollow lower cone structure, and its inner cavity is a blasting gas energy storage chamber 12. The inner conical part of the lower cone is provided with a bottom plate with a central hole for the pull rope to pass through. An explosion device 5 is positioned above the central hole in the base plate, with the entrance hole 6 located above the central hole. The explosion device 5 is vertically connected to the center of the explosion gas storage chamber 12. The explosion device 5 can be a pull-tab tube or any other tubular explosive object capable of generating explosive gas impact energy through detonation. One end of the pull rope 7 is fixedly connected to the bottom of the explosion device, while the other end passes through the pull rope entrance hole 6 in the center of the lower base plate, extends through the lower hollow cavity of the tube section, and is fixed to the outer wall of the tube section. Thus, the entire assembly forms a modified explosion firework. When the firework is ignited, simply pulling the pull rope 7, which extends from the lower end of the inner cavity of the tube section 8, detonates the explosion device 5 in the explosion gas storage chamber 12, generating a large amount of gas with impact energy.

[0027] Because the explosive gas gathers in the narrow cone-shaped explosive gas energy storage chamber, the instantaneous gas energy impacts the bottom support plate 4 of the effect object above. Under the work of the impact force, the bottom support plate 4 of the effect object is forced to act like a cylinder piston to release the gas energy of the mixed effect object 3 stored in the upper effect object chamber 9 toward the top port of the effect section 2 and to blow open the top cover plate 1 of the effect section. At this time, the mixed effect object of the effect is sprayed into the air like a fairy scattering flowers. Its scattering pattern is colorful and colorful, making the scene of the ignition seem as if it were created by nature.

[0028] In one preferred embodiment described above, the object used to create the lace effect is a colored paper flower, colored paper strip, or other lightweight colored strips or ribbons, or it can also be various animals made of paper-plastic material, or miniature toys, etc.

[0029] In one of the preferred embodiments described above, as shown in the figure, the latte art effect section (2) is a circular tube structure or a polygonal geometric tube structure, and the shape of the latte art effect section matches the shape of the tube section.

[0030] Although this utility model has been described in conjunction with different preferred embodiments, it should be understood that modifications to its structure and changes to its components can be made without departing from the scope of the claims. In other words, the above-described embodiments are merely illustrative of the technical solutions of this utility model and should not be construed as limiting the utility model in any way. Those skilled in the art should understand that this utility model has various known structural forms and / or material substitutions / alternatives, and all such substitutions / alternatives should be covered within the protection scope of this utility model without departing from its essential meaning.
