Description

Technical Field

[0001] This utility model relates to the technical field of gas stove accessories, and in particular to a flame distributor for a hydrogen gas stove. Background Technology

[0002] Hydrogen is a clean and renewable energy source. It burns quickly and is prone to explosion. Existing hydrogen gas stoves have a burner consisting of a central burner, an umbrella-shaped hollow tube, and a nozzle. The bottom of the central burner is threaded to the top of the umbrella-shaped hollow tube, and the bottom of the umbrella-shaped hollow tube is threaded to the top of the nozzle. The circumferential sidewalls and top of the burner holes are provided with burner holes, the diameter of which is 0.7mm-1.2mm. The hexagonal cavity sidewalls of the nozzle either do not have air inlets or each sidewall has multiple air inlets with a diameter of less than 1.2mm.

[0003] In existing technology, the diameter of the burner hole is less than 1.2mm, resulting in insufficient gas output and incomplete combustion. Furthermore, the lack of air inlets on the hexagonal cavity sidewall of the nozzle leads to insufficient primary air supply and incomplete combustion. Additionally, the nozzle has multiple air inlets with a diameter of less than 1.2mm on each sidewall of the hexagonal cavity. Since hydrogen molecules are the smallest among gases, a small amount of hydrogen will escape from the air inlets no matter how small they are. If hydrogen accumulates inside the gas stove to a certain amount, it can cause an explosion, thus posing a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a burner for a hydrogen gas stove with top air intake, to solve the problems in the background technology where the diameter of the burner hole is less than 1.2mm, resulting in insufficient gas output and incomplete combustion. Furthermore, if there are no air intake holes on the side wall of the hexagonal cavity of the nozzle, there will be no primary air supply, leading to incomplete combustion. If multiple air intake holes with a diameter of less than 1.2mm are provided on each side wall of the hexagonal cavity of the nozzle, because hydrogen molecules are the smallest among gases, a small amount of hydrogen will escape from the holes no matter how small they are. If the hydrogen accumulates inside the gas stove to a certain amount, it will cause an explosion, thus posing a significant safety hazard.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a burner for a top-intake hydrogen gas stove, comprising a burner, a hexagonal hollow tube, and a hexagonal nozzle, characterized in that the burner is threaded onto the outer surface of the hexagonal hollow tube, and the hexagonal hollow tube is threaded onto the outer surface of the hexagonal nozzle; the hexagonal hollow tube is disposed on the outer panel of the stove; and the inner wall of the burner is provided with multiple burner holes, the diameter of which is 1.2mm-1.8mm.

[0006] Preferably, the hexagonal cavity with the hexagonal hollow tube is provided with multiple air inlets, and the diameter of each air inlet is less than 1.0 mm.

[0007] Preferably, the top of the hexagonal nozzle is conical, and the conical tip of the hexagonal nozzle extends into the interior of the hexagonal hollow tube.

[0008] Preferably, the hexagonal nozzle has an air inlet at its conical tip along its centerline, and the diameter of the air inlet is positively correlated with the power of the hydrogen stove.

[0009] Preferably, the hexagonal nozzle does not have an air inlet hole on its hexagonal cavity sidewall.

[0010] Preferably, the flame distributor, the hexagonal hollow tube, and the hexagonal nozzle are all made of metal.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] First, this utility model increases the diameter of the flame distribution hole to ensure sufficient hydrogen output, more complete combustion, and improved thermal efficiency. The design of the air inlet with a hexagonal hollow tube on the outside of the furnace supplements primary air, promotes complete combustion of hydrogen, and reduces the emission of harmful gases. At the same time, the hexagonal cavity sidewall of the nozzle does not have an air inlet to prevent hydrogen from escaping into the furnace body, avoids the risk of explosion caused by hydrogen accumulation, reduces the occurrence of backfire, and improves the safety of use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3A burner for a top-air-intake hydrogen gas stove includes a burner 1, a hexagonal hollow tube 2, and a hexagonal nozzle 3. The burner 1 is threaded onto the outer surface of the hexagonal hollow tube 2, and the hexagonal hollow tube 2 is threaded onto the outer surface of the hexagonal nozzle 3. The hexagonal hollow tube is mounted on the outer panel of the stove. The inner wall of the burner 1 is provided with multiple burner holes 5, and the diameter of the multiple burner holes 5 is 1.2mm-1.8mm.

[0019] By increasing the diameter of the flame distribution hole 5, sufficient hydrogen output is ensured, combustion is more complete, and thermal efficiency is improved. The design of the air inlet hole 4 with hexagonal hollow tube 2 supplements primary air, promotes complete combustion of hydrogen, and reduces the emission of harmful gases. At the same time, the side wall of the hexagonal cavity 3 of the nozzle does not have an air inlet hole to prevent hydrogen from escaping into the furnace body, avoid the risk of explosion caused by hydrogen accumulation, reduce the occurrence of backfire, and improve the safety of use.

[0020] Specifically, the hexagonal cavity with hexagonal hollow tube 2 is provided with multiple air inlets 4, and the diameter of each air inlet 4 is less than 1.0 mm.

[0021] The above technical solution, through the design of the air inlet 4 with hexagonal hollow tube 2, replenishes primary air, promotes complete combustion of hydrogen, and reduces the emission of harmful gases.

[0022] Specifically, the top of the hexagonal nozzle 3 is conical, and the conical tip of the hexagonal nozzle 3 extends into the interior of the hexagonal hollow tube 2.

[0023] The above technical solution allows the material to be injected into the hexagonal hollow tube 2 through the hexagonal nozzle 3.

[0024] Specifically, the hexagonal nozzle has an air inlet at its conical tip along the center line, and the diameter of the air inlet is positively correlated with the power of the hydrogen stove.

[0025] Through the above technical solution, the hexagonal nozzle 3 is positively correlated with the power of the hydrogen stove.

[0026] Specifically, the hexagonal nozzle 3 does not have an air inlet on its hexagonal cavity sidewall.

[0027] By employing the above technical solution, the absence of air inlet holes on the side wall of the hexagonal cavity 3 of the nozzle prevents hydrogen from escaping into the furnace body, avoids the risk of explosion caused by hydrogen accumulation, reduces the occurrence of backfire, and improves operational safety.

[0028] Specifically, the fire distributor 1, the hexagonal hollow tube 2, and the hexagonal nozzle 3 are all made of metal.

[0029] Through the above technical solution, the metal material can withstand the high temperature generated during hydrogen combustion, and is not easily deformed or damaged, ensuring that the igniter works stably in a long-term high-temperature environment. Furthermore, the igniter 1, the hexagonal hollow tube 2, and the hexagonal nozzle 3 are connected by threads, which facilitates disassembly and cleaning and reduces maintenance costs.

[0030] During use, by increasing the diameter of the flame distribution hole 5, sufficient hydrogen output is ensured, combustion is more complete, and thermal efficiency is improved. The design of the air inlet hole 4 with hexagonal hollow tube 2 supplements primary air, promotes complete combustion of hydrogen, and reduces the emission of harmful gases. At the same time, the side wall of the hexagonal cavity 3 of the nozzle does not have an air inlet hole to prevent hydrogen from escaping into the furnace body, avoid the risk of explosion caused by hydrogen accumulation, reduce the occurrence of backfire, and improve the safety of use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
