Description

Technical Field

[0001] This invention relates to the field of fireworks technology, and in particular to an environmentally friendly firework and its manufacturing method. Background Technology

[0002] The core principle of modern fireworks, firecrackers, and firecrackers is that an oxidizer provides oxygen, and sulfur powder or charcoal serves as the combustible material. Fireworks, in pursuit of vibrant colors, incorporate metal salts, and whistling agents are added to ensure a powerful effect during ignition. These substances produce nitrogen oxides, sulfur oxides, and generate significant amounts of dust pollution. While electronic firecrackers are indeed sold on the market, they primarily simulate the sound and light effects of real firecrackers through audio-visual technology, lacking the tangible enjoyment of actually setting them off. Summary of the Invention

[0003] The purpose of this invention is to provide an environmentally friendly firework and its manufacturing method, which can reduce environmental pollution and have the same effect as traditional fireworks.

[0004] The technical solution adopted by the environmentally friendly fireworks and their manufacturing method disclosed in this invention is as follows: An environmentally friendly firework includes an outer shell, a gasbag, and a conical barrel. The gasbag is disposed inside the outer shell, and the conical barrel is fitted over the gasbag. The lower part of the inner wall of the conical barrel is in contact with and sealed to the surface of the gasbag. A receiving cavity is formed between the upper part of the gasbag and the inside of the conical barrel. The receiving cavity is filled with a propellant. The gasbag contains powdered chemicals, including sugar powder and flame coloring agent. A cover plate is provided on the top of the conical barrel. The cover plate is fixedly connected to the outer shell. A lead wire is provided on the surface of the cover plate, and the lead wire extends into the receiving cavity.

[0005] As a preferred embodiment, the inner wall of the airbag is coated with paraffin to form a rough surface, and the medicinal powder adheres to the inner wall of the airbag.

[0006] As a preferred embodiment, the mass ratio of the sugar powder, the combustion agent, and the flame coloring agent is 55:30:15.

[0007] As a preferred embodiment, the combustion agent comprises potassium perchlorate, carbon powder, and calcium oxide.

[0008] As a preferred embodiment, the flame colorant comprises any one or more of sodium chloride, potassium chloride, calcium chloride, copper chloride, barium sulfate, and strontium chloride.

[0009] As a preferred embodiment, both the outer shell and the cover are made of cardboard, and the cover is covered with a layer of clay.

[0010] As a preferred embodiment, the lower end of the outer shell surface is provided with a plurality of support plates, which are arranged around the center of the outer shell.

[0011] A method for manufacturing the aforementioned environmentally friendly fireworks includes the following steps: The powdered sugar is mixed with the flame coloring agent to form a powder, which is then added to the gasbag. Compressed gas is introduced into the airbag, which is placed inside the outer shell, and a conical barrel is fitted on top of the airbag; The propellant is added to the spacer above and inside the cone-shaped barrel to form a storage cavity for holding the fireworks materials; One end of the lead wire is connected to the storage cavity, and the other end extends out of the outer shell; Then fix the cover plate to the outer shell.

[0012] The beneficial effects of the environmentally friendly fireworks disclosed in this invention are as follows: The outer shell is placed on the ground, and after the fuse is lit, the fuse ignites the propellant, causing it to burn rapidly and burn through the gas chamber. Sugar powder and flame coloring agent mixed in the gas chamber are ejected. Through the combustion of the propellant, the beautiful fireworks are formed. Furthermore, the outer shell can be shaken quickly before use to ensure the powder is fully diffused within the gas chamber. The main components of the powder are sugar powder and flame coloring agent; therefore, incomplete or insufficient combustion of the powder will not produce toxic or harmful substances, avoiding environmental pollution. It also reduces the cost of fireworks production while achieving the same effect as traditional fireworks. Attached Figure Description

[0016] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2 An environmentally friendly firework includes an outer shell 10, an airbag 11, and a conical barrel 12. The airbag 11 is disposed inside the outer shell 10, and the conical barrel 12 is fitted on top of the airbag 11. The lower part of the inner wall of the conical barrel 12 is in contact with and sealed to the surface of the airbag 11. A receiving cavity 121 is formed between the upper part of the airbag 11 and the inside of the conical barrel 12. The receiving cavity 121 is filled with a propellant. The airbag 11 contains powder, including sugar powder and flame coloring agent. A cover plate 13 is provided on the top of the conical barrel 12. The cover plate 13 is fixedly connected to the outer shell 10. A lead wire 14 is provided on the surface of the cover plate 13, and the lead wire 14 extends into the receiving cavity 121.

[0017] Place the outer casing 10 on the ground, ignite the fuse 14, and use the fuse 14 to ignite the propellant, causing the propellant to burn rapidly and burn through the gas bag 11. The gas bag 11 contains sugar powder and flame coloring agent, which are sprayed out. After the propellant burns, the beautiful fireworks you see are formed. Before use, the outer casing 10 can be shaken quickly to allow the powder to spread fully in the gas bag 11. The main components of the powder are sugar powder and flame coloring agent. Therefore, when the powder is not fully burned or not fully burned, no toxic or harmful substances will be produced, avoiding environmental pollution. At the same time, it also reduces the cost of fireworks production and achieves the effect of traditional fireworks.

[0018] The inner wall of the airbag 11 is coated with paraffin to form a rough surface. The powder adheres to the inner wall of the airbag 11, so that when the airbag 11 is burned through, the powder can be better ejected with the gas in the airbag 11, avoiding accumulation at the bottom of the airbag 11 and affecting the fireworks display effect.

[0019] The mass ratio of sugar powder, combustion agent and flame coloring agent is 55:30:15. Since sugar powder and flame coloring agent are set in the gasbag 11 as powder, when the gasbag 11 burns through and sprays out powder, a small amount of powder will inevitably remain in the gasbag 11. Therefore, increasing the ratio of sugar powder and flame coloring agent can ensure that a sufficient amount of powder is sprayed out.

[0020] In the above scheme, the combustion agent consists of potassium perchlorate, carbon powder and calcium oxide, and the flame coloring agent consists of any one or more of sodium chloride, potassium chloride, calcium chloride, copper chloride, barium sulfate and strontium chloride, so that no toxic or harmful substances are produced when the powder is not fully burned or is incompletely burned.

[0021] Please refer to Figure 3 In the actual manufacturing process, the airbag 11 in the above structure can be replaced by a balloon, and an elastic band 15 is fitted on the outside of the balloon 11. The elastic band 15 is used to squeeze the balloon 11, and the elastic band 15 forms a squeezing force on the inside of the balloon 11. So when the balloon 11 burns through, under the action of the elastic band 15 and the gas inside the balloon 11, there is enough pressure to accelerate the speed of the powder spraying out, so that the powder can be fully burned.

[0022] Both the outer casing 10 and the cover plate 13 are made of cardboard, which can be recycled in an environmentally friendly manner. The cover plate 13 is covered with a clay layer 16, which serves as a protective layer to prevent the leakage of the combustible.

[0023] The lower end of the outer shell 10 is provided with several support plates 17, which are arranged around the center of the outer shell 10 to facilitate placement on the ground when it is set off.

[0024] A method for manufacturing the above-mentioned environmentally friendly fireworks includes the following steps: The powdered sugar and the flame coloring agent are mixed to form a powder, which is then added to the airbag 11. Compressed gas is introduced into the airbag 11, which is placed in the outer shell 10, and the conical barrel 12 is fitted on top of the airbag 11; The propellant is added to the spacer 11 above the gasbag 11 and inside the cone-shaped barrel 12 to form a storage cavity 121 for holding the fireworks materials; One end of the lead wire 14 is connected to the storage cavity 121, and the other end extends out of the outer shell 10; Then fix the cover plate 13 to the outer shell 10.

[0025] The air pressure inside airbag 11 is 0.5 MPa, and airbag 11 is made of PE.

[0026] This invention provides an environmentally friendly firework and its manufacturing method. The outer shell is placed on the ground, and the fuse is lit. The fuse then ignites the propellant, causing it to burn rapidly and burn through the gas chamber. Sugar powder and flame coloring agent mixed in the gas chamber are ejected. The combustion of the propellant forms the beautiful firework. Before use, the outer shell can be shaken quickly to ensure that the powder is fully diffused within the gas chamber. The main components of the powder are sugar powder and flame coloring agent. Therefore, no toxic or harmful substances are produced when the powder is not fully burned, thus avoiding environmental pollution. This also reduces the cost of firework manufacturing while achieving the same effect as traditional fireworks.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
