Description

Technical Field

[0001] The utility model belongs to the field of salutes, in particular to a hydrogen-oxygen salute. Background Art

[0002] During traditional festivals, most units, families or individuals will set off fireworks to increase the festive mood. The products used are generally dangerous products such as gunpowder products, pressure vessels and gas tanks. Salutes are cannons fired during grand ceremonies or to welcome distinguished guests. The burning salute conveys a kind of respect and is often used in folk celebrations, weddings and welcoming brides. Although salutes are now common, the overall assembly strength of salutes is average and needs to be improved. At the same time, the harmful gases produced after the gas is burned float in the air, often polluting the environment and being unfriendly to the environment. Utility Model Content

[0003] The utility model aims to provide a hydrogen-oxygen salute, which has the advantages of increasing the overall assembly strength of the hydrogen-oxygen salute, facilitating the flow generated by gas explosion to bring out moisture, and having the function of not generating harmful gases.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: a hydrogen-oxygen salute, including an explosion-proof cylinder, the bottom of the explosion-proof cylinder is connected to a gas storage cylinder, both ends of the top of the explosion-proof cylinder are connected to an upper anti-arcing boss, both ends of the bottom of the gas storage cylinder are connected to a lower anti-arcing boss, one end of the upper anti-arcing boss and the lower anti-arcing boss are cast and pre-embedded with ignition needles, and a bracket is provided on the surface of the gas storage cylinder.

[0005] The above technical solution is adopted: in the use of the hydrogen-oxygen salute, the ignition needle is cast and embedded in one end of the upper anti-arcing boss and the lower anti-arcing boss, wherein the upper anti-arcing boss and the lower anti-arcing boss are used to prevent the product moisture after the hydrogen-oxygen gas explosion from causing unstable ignition to the ignition needle, and the protrusion of the upper anti-arcing boss and the lower anti-arcing boss prevents the accumulation of water after the long-term combustion of the gas from causing a gap short circuit to the ignition needle. After the ignition needle is cast and integrated, the overall assembly strength of the hydrogen-oxygen salute will be increased. The air guide pipe is located in the center of the explosion-proof cylinder and the gas storage cylinder, isolated from the ignition needle and at a safe distance, and the air guide pipe is a PVC casting, so no static sparks will be generated when the gas flows through, avoiding mis-ignition during air intake. When the air is inletted, a bottom-inserted one-way valve is used to introduce the mixed hydrogen and oxygen gas, which then enters the gas cylinder through the gas pipe. The one-way valve takes in air from the bottom, and after the gas is produced by the external electrolyzer, it opens after reaching a certain pressure through the one-way valve, enters the gas pipe, and then enters the gas cylinder for ignition. The one-way valve can only ventilate from bottom to top, and the opposite direction is cut off. Therefore, after the gas in the gas cylinder explodes, it can no longer continue to burn to the front end through the gas pipe. The exhaust duct is designed according to the expansion coefficient generated by the combustion of the gas in the gas cylinder. After a certain proportion of the exhaust duct is narrowed to form a certain amount of flow rate, the colored paper fireworks required by the muzzle are torn and ejected, thereby achieving the visual effect of explosion and ejection of colored flowers. The bracket and the exhaust duct are integrated into a certain proportion, which does not hinder the outflow of the airflow generated when the gas burns and bursts, and the bracket support also plays a good role in fixing and supporting the gas cylinder. In addition, after the gas is burned, as the number of combustions increases, the water produced by the hydrogen and oxygen gas will accumulate and form a certain amount of water. The waterproof skirt will effectively block the flow of water, so that the water stays outside the waterproof skirt, and the flow generated by the gas explosion will bring the water out of the explosion-proof tube chamber. The salute has an anti-backfire check valve during use, which also increases the strength of the overall assembly.

[0006] The utility model is further configured that the explosion-proof cylinder and the gas storage cylinder are provided with mutually communicating air guide pipes inside.

[0007] The above technical solution is adopted: the air guide pipe is located in the center of the explosion-proof cylinder and the gas storage cylinder, isolated from the ignition needle and at a safe distance, and the air guide pipe is a PVC casting, so no static sparks are generated when the gas flows through, avoiding mis-ignition during air intake.

[0008] The utility model is further configured that a one-way valve connected to the air guide pipe is fixedly installed at the bottom of the air storage cylinder.

[0009] The above technical solution is adopted: the gas storage cylinder is allowed to take in air from the bottom through the one-way valve, and the gas produced by the external electrolytic cell opens after reaching a certain pressure through the one-way valve, enters the air guide pipe and then enters the gas storage cylinder to realize ignition.

[0010] The utility model is further configured that the number of the brackets is four and they are distributed in a circle on the surface of the gas storage cylinder.

[0011] By adopting the above technical solution, the bracket can well fix and support the gas storage cylinder.

[0012] The utility model is further configured such that an exhaust duct is formed between two adjacent brackets, and the bracket and the exhaust duct are of an integrally formed design.

[0013] The above technical solution is adopted: a certain flow rate is formed by narrowing the exhaust duct by a certain proportion, so that the colored paper fireworks required by the muzzle are torn and sprayed out, thereby achieving the visual effect of explosion and spraying colored fireworks, and the bracket and the exhaust duct are integrated into one and arranged in a certain proportion so as not to hinder the outflow of the airflow generated by the combustion and explosion of the gas.

[0014] The utility model is further configured that the surface of the explosion-proof cylinder is formed with a conical surface.

[0015] By adopting the above technical solution, the cone-shaped surface enables the explosion-proof tube to form a cone-shaped structure.

[0016] The utility model is further configured that the surface of the air storage cylinder is sleeved with a waterproof skirt.

[0017] By adopting the above technical solution, the flow of water can be effectively blocked by the waterproof skirt, so that the water stays outside the waterproof skirt.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. In the use of the hydrogen-oxygen salute of the utility model, the ignition needle is cast and embedded in one end of the upper anti-arc boss and the lower anti-arc boss, wherein the upper anti-arc boss and the lower anti-arc boss are used to prevent the product moisture after the hydrogen-oxygen gas explosion from causing unstable ignition to the ignition needle. The protrusion of the upper anti-arc boss and the lower anti-arc boss prevents the accumulation of water after the long-term combustion of gas from causing a gap short circuit to the ignition needle. After the ignition needle is cast and integrated, the overall assembly strength of the hydrogen-oxygen salute will be increased;

[0020] 2. In the use of the hydrogen-oxygen salute of the utility model, after the gas is burned, as the number of combustions increases, the water generated after the hydrogen-oxygen gas is burned will accumulate and form a certain amount of accumulated water. The waterproof skirt will effectively block the flow of water, so that the water stays outside the waterproof skirt, and the flow generated by the gas explosion will bring the water out of the explosion-proof tube chamber, and the explosion of the salute does not produce harmful gases.

After the ignition needle 1 is cast and integrated with the whole, the overall strength of the hydrogen-oxygen salute will be increased. In the use of the hydrogen-oxygen salute, after the gas is burned, as the number of combustions increases, the water generated after the hydrogen-oxygen gas is burned will accumulate and form a certain amount of accumulated water. The waterproof skirt 5 will effectively block the flow of water, so that the water stays outside the waterproof skirt 5, and the flow generated by the gas explosion will bring the water out of the explosion-proof tube 11 chamber.

[0028] refer to Figure 3 The explosion-proof cylinder 11 and the gas storage cylinder 10 are provided with interconnected air guide pipes 3, which are located at the center of the explosion-proof cylinder 11 and the gas storage cylinder 10, and are isolated from the ignition needle 1 at a safe distance. The air guide pipe 3 is a PVC casting, so no static sparks are generated when the gas flows through, thereby avoiding mis-ignition during air intake.

[0029] refer to Figure 2A one-way valve 7 connected to the air guide pipe 3 is fixedly installed at the bottom of the air storage cylinder 10. The one-way valve 7 allows the air storage cylinder 10 to take in air from below.

[0031] refer to Figure 3 An exhaust duct 9 is formed between two adjacent brackets 4. The bracket 4 and the exhaust duct 9 are of an integrally formed design. A certain flow rate is formed by narrowing the exhaust duct 9 in a certain proportion, so that the colored paper fireworks required by the muzzle are torn and ejected, thereby achieving a visual effect of exploding and ejecting colored fireworks.

The one-way valve 7 takes in air from the bottom, and after the gas is produced by the external electrolytic cell, it opens after reaching a certain pressure through the one-way valve 7, enters the gas guide pipe 3, and then enters the gas storage cylinder 10 for ignition. The one-way valve 7 can only ventilate from bottom to top, and the opposite direction is cut off.
