Description

Technical Field

[0001] The invention relates to the technical field of fireworks, in particular to a fireworks rocket structure with a hollow structure and reverberation. Background Art

[0002] Fireworks, as an ornamental pyrotechnic object, are usually made of gunpowder and other chemicals, which produce brilliant light, color and sound effects when ignited. Fireworks originated in China, and their original purpose was to ward off evil spirits and avoid disasters. Later, they gradually developed into an entertainment item in festivals and major events. The types and designs of modern fireworks are more diverse. In addition to the common ground fireworks, rocket fireworks (or aerial fireworks) are a special form that can explode in the air and produce brilliant light in the sky.

[0003] With the continuous development of fireworks technology, traditional ground fireworks are gradually unable to meet the audience's demand for more spectacular aerial effects. Rocket fireworks were developed in this context, mainly to overcome the limitations of ground fireworks viewing angles and to achieve higher, farther, and more spectacular effects. However, rocket fireworks have also encountered many technical challenges during their development, which has also led to continuous improvements in the structural design of rocket fireworks.

[0004] In the traditional structural design of fireworks and rockets, a relatively simple gunpowder filling method is usually adopted, and a single thrust source is relied on to achieve launch. Most existing fireworks and rocket structures are filled with solid gunpowder, and the gunpowder combustion area is small, resulting in a slow combustion speed and limited thrust. Although this structure can realize the basic functions of fireworks and rockets, due to its low combustion efficiency, its thrust output is insufficient, and the flight height and flight distance are subject to certain restrictions. In addition, the gunpowder arrangement and ignition method of existing fireworks and rockets are relatively simple, and the gunpowder is mostly burned once, lacking a multi-stage thrust design, resulting in a short burning time, insufficient thrust, and inability to achieve a higher and farther flight effect. At the same time, traditional fireworks and rocket designs often do not specially design the acoustic effects during combustion, resulting in a relatively monotonous sound produced during the combustion process, lacking a shocking auditory effect, and failing to meet the comprehensive visual and auditory viewing requirements of modern fireworks products.

[0005] To this end, those skilled in the art provide a firework rocket structure with a hollow structure and reverberation to solve the problems raised in the above background technology. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a firework rocket structure with a hollow structure and reverberation, which solves the problem of the prior art that the acoustic effect is too monotonous and the flight thrust is weak.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A hollow structure with reverberation fireworks rocket structure, comprising:

[0008] The outer tube forms the outer structure of the rocket;

[0009] An aluminum tube is arranged inside the outer tube to form a hollow structure of the rocket;

[0010] The gunpowder mechanism is set in the inner cavity of the aluminum tube and is used to ignite and generate thrust and flash resonance;

[0011] The inner cylinder shell is arranged on one side of the aluminum tube and is used to form a first layer of sealing;

[0012] Built-in fuse for connecting and igniting the gunpowder mechanism;

[0013] External fuse for initial ignition.

[0014] Preferably, the gunpowder mechanism includes a first gunpowder, a second gunpowder and a third gunpowder, the first gunpowder and the second gunpowder are sequentially arranged in the cavity between the aluminum tube and the outer cylinder, and the third gunpowder is arranged in the inner cavity of the inner cylinder shell.

[0015] Preferably, the first gunpowder cavity is hollow, and the outer wall is fixed to the inner cavity of the aluminum tube to increase the combustion area and generate flash frequency resonance.

[0016] Preferably, a wooden strip is installed on one side of the outer wall of the outer cylinder to balance the outer cylinder so as to keep it in a vertical state.

[0017] Preferably, the external fuse is located at the bottom of the outer tube, and one side of the external fuse is connected to the first gunpowder.

[0018] Preferably, the built-in fuse is located on one side of the second gunpowder, and one side of the built-in fuse is connected to the third gunpowder.

[0019] Preferably, an inner cylinder cover is fixed to one side of the inner cylinder shell for forming a seal in the inner cavity of the inner cylinder shell to maintain the combustion density of the gunpowder mechanism.

[0020] Preferably, an outer cylinder top shell is installed on the top of the outer cylinder, and an outer cylinder top cover is fixed on the top of the outer cylinder top shell to achieve a second layer of sealing.

[0021] Preferably, the weight ratio of the first gunpowder, the second gunpowder and the third gunpowder is 2:1.5:2.

[0022] A method for using a firework rocket structure with a hollow structure and an echo, according to a firework rocket structure with a hollow structure and an echo, comprises the following steps:

[0023] Insert the wooden strips firmly into the ground or guide holes to ensure the rocket is stable during launch and avoid tilting or deviation;

[0024] Make sure the external fuse is exposed and in the ignition position, and make sure the fuse is not damp or damaged;

[0025] The external fuse is ignited using an ignition tool. After the external fuse is ignited, the flame is transferred to the internal fuse through the first gunpowder and the second gunpowder, thereby guiding the flame into the interior of the rocket;

[0026] The external fuse first ignites the first powder at the bottom of the rocket. The first powder is responsible for generating the initial thrust, pushing the rocket away from the launch point and starting to rise.

[0027] When the first gunpowder is completely burned, the flame is transferred to the second gunpowder through the built-in fuse. The second gunpowder continues to burn, providing mid-stage thrust and further driving the rocket into flight.

[0028] After the second powder has burned out, the built-in fuse transfers the flame to the third powder at the top of the rocket, which provides the final thrust to bring the rocket to its highest point;

[0029] When the rocket rises to the top, the combustion pressure inside the rocket is formed through the sealing design of the outer tube top shell and the outer tube top cover, ensuring that the gunpowder is fully burned and the thrust output is maximized;

[0030] When the rocket finishes burning, due to the hollow structure and the top sealing structure, the sound waves are reflected and resonated, and the strobe echo effect gradually decays along the rocket's flight path.

[0031] The present invention provides a hollow structure with a reverberant fireworks rocket structure.

[0032] Beneficial effects:

[0033] The present invention significantly increases the combustion area and accelerates the combustion speed by adopting the hollow structure design of the first gunpowder, so that the gunpowder can release energy more fully, thereby providing more powerful thrust; at the same time, through the layered design and reasonable gunpowder weight ratio, the continuous output of multiple thrusts is achieved, ensuring that the thrust of the rocket is continuous and stable during flight; in addition, the hollow structure of the first gunpowder also forms an airflow channel, so that the combustion gas produces sound wave reflection when flowing, bringing about a significant strobe echo effect, so that the rocket not only has a powerful thrust during the combustion process, but also can produce a unique acoustic effect at the same time, thereby greatly improving the performance and ornamental value of the rocket.

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] Please see attached Figure 1 The embodiment of the present invention provides a hollow structure with a reverberant firework rocket structure, comprising:

[0040] The outer tube 2 constitutes the external structure of the rocket; a wooden strip 1 is installed on one side of the outer wall of the outer tube 2 to counterweight the outer tube 2 so that it remains in a vertical state.

[0041] Specifically, the main function of the wooden strip 1 is to serve as the counterweight of the rocket. By adjusting the weight distribution, the rocket is ensured to be in a vertical state before launch to prevent tilting or instability caused by the center of gravity shift. The wooden strip 1 can be firmly connected to the outer wall of the outer tube 2 by welding, snaps or bolts to ensure that it will not fall off or shift during the transportation, launch and flight of the rocket.

[0042] The aluminum tube 3 is arranged inside the outer tube 2 to form a hollow structure of the rocket;

[0043] Specifically, the aluminum tube 3 is connected to the inner wall of the outer tube 2 through a plurality of fixing brackets to ensure that it remains stable during the combustion process. A gap of 5 to 8 mm is formed between the aluminum tube 3 and the outer tube 2, which is used to accommodate multiple layers of gunpowder (including the first gunpowder 4, the second gunpowder 5 and the third gunpowder 6) and provide a gas circulation channel when the gunpowder burns to avoid air flow blockage or excessive air pressure affecting the flight stability of the rocket. The hollow structure of the aluminum tube 3 not only provides a larger space and airway for the combustion of gunpowder, but also helps the high-temperature gas generated by the combustion to be discharged smoothly, thereby improving the thrust output of the rocket. The aluminum tube 3 is usually made of aluminum alloy to ensure good heat resistance and strength in high temperature environments, while reducing the overall weight of the rocket.

[0044] The gunpowder mechanism is arranged in the inner cavity of the aluminum tube 3 and is used for igniting to generate thrust and flash frequency resonance; the gunpowder mechanism includes a first gunpowder 4, a second gunpowder 5 and a third gunpowder 6. The first gunpowder 4 and the second gunpowder 5 are arranged in sequence in the cavity between the aluminum tube 3 and the outer tube 2, and the third gunpowder 6 is arranged in the inner cavity of the inner tube shell 7.

[0045] Specifically, this three-layer gunpowder structure controls the thrust output and combustion process of the rocket through segmented combustion. The first gunpowder 4 and the second gunpowder 5 are arranged in sequence in the cavity between the aluminum tube 3 and the outer tube 2. The layered design ensures that they are ignited in sequence during combustion, pushing the rocket to fly step by step. The first gunpowder 4 has a large hollow structure, which generates initial thrust by increasing the combustion area and accelerating the combustion rate, and at the same time forms an air flow channel to produce a flash echo effect. The third gunpowder 6 is arranged in the inner cavity of the inner tube shell 7 as the final thrust source, which is used to generate additional combustion energy when the rocket flies to the apex, pushing the rocket to reach the maximum flight altitude. Each layer of gunpowder is ignited in series through the built-in fuse 11 to ensure the continuity of the combustion sequence and thrust.

[0046] The first gunpowder 4 has a hollow inner cavity, and its outer wall is fixed to the inner cavity of the aluminum tube 3 to increase the combustion area and generate a flash frequency echo. The weight ratio of the first gunpowder 4, the second gunpowder 5 and the third gunpowder 6 is 2:1.5:2.

[0047] Specifically, the inner cavity of the first gunpowder 4 is designed to be hollow, and its outer wall is fixed to the inner cavity wall of the aluminum tube 3. Through this structural arrangement, the combustion area of ​​the gunpowder is significantly increased, thereby accelerating the combustion speed and improving the thrust output. In addition, the hollow structure of the first gunpowder 4 can form an airflow channel during the combustion process, so that the combustion gas produces sound wave reflection when flowing inside, thereby producing a strobe echo effect. The weight ratio of the first gunpowder 4, the second gunpowder 5 and the third gunpowder 6 is 2:1.5:2. The gunpowder layer designed according to this ratio ensures the stability of the rocket combustion and the gradual release of thrust. The first gunpowder 4 provides the strongest initial thrust, the second gunpowder 5 provides continuous thrust as a mid-stage combustion, and the third gunpowder 6 is responsible for the thrust output in the final stage to ensure that the rocket reaches the expected flight altitude.

[0048] The inner cylinder shell 7 is arranged on one side of the aluminum tube 3 to form a first layer of sealing; an inner cylinder cover 8 is fixed to one side of the inner cylinder shell 7 to form a seal in the inner cavity of the inner cylinder shell 7 to maintain the combustion density of the gunpowder mechanism.

[0049] Specifically, through the seal, the inner tube shell 7 can effectively isolate the external environment, ensure that the gunpowder mechanism is not affected by the outside world during the combustion process, and maintain the combustion pressure and stability inside the rocket. An inner tube cover 8 is fixedly installed on one side of the inner tube shell 7, and the inner tube cover 8 is tightly connected to the inner cavity of the inner tube shell 7, further forming a complete sealed environment. This sealing structure helps to maintain the density and combustion efficiency of the gunpowder mechanism during combustion, ensure that the energy of the gunpowder during combustion will not be lost due to leakage, and improve the thrust output effect of the rocket. The mutual cooperation between the inner tube shell 7 and the inner tube cover 8 ensures the integrity of the internal structure of the rocket, so that the third gunpowder 6 maintains a suitable combustion density and continuous thrust when burning in the inner cavity of the inner tube shell 7.

[0050] The built-in fuse 11 is used to connect and ignite the gunpowder mechanism; the built-in fuse 11 is located on one side of the second gunpowder 5, and one side of the built-in fuse 11 is connected to the third gunpowder 6.

[0051] Specifically, the built-in lead 11 is used to connect and sequentially ignite the gunpowder mechanism in the rocket to ensure that each gunpowder layer burns stably in sequence. The built-in lead 11 is arranged on one side of the second gunpowder 5, and through reasonable wiring design, the correctness of the ignition sequence is ensured. One end of the built-in lead 11 is connected to the third gunpowder 6 to ensure that after the second gunpowder 5 is burned, the flame is smoothly transferred to the third gunpowder 6, so as to achieve continuous output of multiple thrusts. This wiring structure ensures the combustion sequence of the gunpowder mechanism, thereby ensuring the thrust increase and combustion stability of the rocket during flight, while avoiding the situation of thrust interruption or unstable flight trajectory caused by uneven combustion.

[0052] The external fuse 12 is used for initial ignition; the external fuse 12 is located at the bottom of the outer tube 2, and one side of the external fuse 12 is connected to the first gunpowder 4.

[0053] Specifically, the external fuse 12 is arranged at the bottom of the outer tube 2 to facilitate the ignition operation. At the same time, the design of this position makes it more convenient and safer to contact with an external ignition device or a handheld igniter. One end of the external fuse 12 is connected to the first gunpowder 4 to ensure that after the external fuse 12 is ignited, the flame can be directly transferred to the first gunpowder 4 to start the initial combustion process of the rocket. After the first gunpowder 4 is ignited, the flame is guided by the internal fuse 11 and is sequentially transferred to the subsequent gunpowder layers, forming a continuous release of multiple thrusts.

[0054] An outer cylinder top shell 9 is installed on the top of the outer cylinder 2, and an outer cylinder top cover 10 is fixed on the top of the outer cylinder top shell 9 to achieve a second layer of sealing.

[0055] Specifically, an outer tube top shell 9 is installed on the top of the outer tube 2, and an outer tube top cover 10 is installed on the top of the outer tube top shell 9 through a fixed connection device (such as a thread or a buckle). The outer tube top cover 10 and the outer tube top shell 9 are tightly matched to form a second layer of sealing structure inside the rocket. This double-layer sealing design ensures that the gas pressure inside the rocket can be effectively accumulated during the combustion process of the gunpowder mechanism, avoiding gas leakage during combustion, and improving the combustion efficiency and the stability of the thrust output. In addition, this sealing structure can effectively protect the gunpowder and fuse inside the rocket from interference from the external environment (such as wind, moisture, etc.), thereby ensuring that the rocket maintains structural integrity and normal function during ignition and flight.

[0059] Make sure the external fuse 12 is exposed and in the ignition position, and ensure that the fuse is not damp or damaged;

[0060] The external fuse 12 is ignited using an ignition tool. After the external fuse 12 is ignited, the flame is transferred to the internal fuse 11 through the first gunpowder 4 and the second gunpowder 5, thereby guiding the flame into the interior of the rocket;

[0061] The external fuse 12 first ignites the first gunpowder 4 at the bottom of the rocket, which is responsible for generating the initial thrust, pushing the rocket away from the launch point and starting to rise;

[0062] When the first gunpowder 4 is completely burned, the flame is transferred to the second gunpowder 5 through the built-in fuse, and the second gunpowder continues to burn, providing mid-stage thrust to further propel the rocket into flight;

[0063] After the second gunpowder 5 has burned, the built-in fuse 11 transfers the flame to the third gunpowder 6 located at the top of the rocket, which provides the final thrust to make the rocket reach its highest point;

[0064] When the rocket rises to the top, the combustion pressure inside the rocket is formed through the sealing design of the outer tube top shell 9 and the outer tube top cover 10, ensuring that the gunpowder is fully burned and the thrust output is maximized;

[0065] When the rocket finishes burning, due to the hollow structure and the top sealing structure, the sound waves are reflected and resonated, and the strobe echo effect gradually decays along the rocket's flight path.
