Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a stainless steel precision-cast gas stove fire distributor. Background Art

[0002] Gas burners (also known as stoves) are key components in gas cookers. Their primary function is to direct and evenly distribute gas across the burner surface, ensuring sufficient combustion and providing a stable heat source. Currently, common gas burners on the market are typically made of cast iron, aluminum alloy, or copper. However, these materials present significant safety risks.

[0003] First, cast iron gas burner heads are prone to gas leaks due to the poor density of cast iron. Furthermore, the low surface finish of cast iron castings can easily cause gas flow disturbances during gas circulation, leading to incomplete combustion. This not only increases gas consumption and reduces combustion efficiency, but also leads to the emission of harmful gases, polluting the environment. More seriously, gas leaks can cause fires, posing a significant safety hazard.

[0004] Secondly, although aluminum alloy gas burners offer improved surface finish and density, their low melting point makes them susceptible to deformation at high temperatures. This deformation can alter the clearance between the burner and the burner cap, leading to safety issues such as gas leaks. Furthermore, long-term use of aluminum alloy at high temperatures can lead to structural fatigue, further increasing safety risks.

[0005] Copper gas burners perform slightly better in these aspects, with a higher melting point and less deformation. However, they also present some challenges. Copper easily oxidizes at high temperatures, which alters its physical properties and affects the burner's lifespan and safety. More importantly, copper is expensive, significantly increasing manufacturing costs and reducing market competitiveness. Therefore, further improvements are necessary. Utility Model Content

[0010] Furthermore, the second fire distribution cover is disc-shaped, and its cross section is a right-angled trapezoid with an open lower end. The outer cylindrical surface of the second fire distribution cover is provided with a first fire hole ring and a second fire hole ring distributed up and down.

[0011] Furthermore, the first flame-spraying hole ring is located above the second flame-spraying hole ring, and the diameter of the first flame-spraying hole ring is larger than the diameter of the second flame-spraying hole ring.

[0012] Furthermore, the conduction paths of the first flame-spraying hole ring and the second flame-spraying hole ring are arranged in an inclined shape with the inner side lower and the outer side higher.

[0013] Furthermore: the bottom of the outer ring of the second ignition distributor cover extends downward with an outer buckle ring, which extends into the second gas mixing tank and is connected to the base; the inner ring of the second ignition distributor cover extends downward with an inner buckle ring, which extends into the outer cylindrical surface of the second gas mixing tank and is connected to the base.

This feature ensures the stability and safety of the ignition switch in high temperature environments and avoids safety hazards such as gas leakage caused by material deformation.

[0019] 5. Stainless steel has excellent oxidation resistance and can maintain its physical properties in high temperature and high humidity environments, extending the service life of the ignition switch. Compared with the problem of copper being easily oxidized, the use of stainless steel is more reliable and reduces the performance degradation and safety hazards caused by oxidation.

[0026] The present invention is further described below in conjunction with the accompanying drawings. A stainless steel precision-cast gas stove ignition distributor comprises a base 1, with a concave first gas mixing groove 2 and a second gas mixing groove 3 concentrically disposed on the top of the base 1. The bottom of the first gas mixing groove 2 is in communication with an air intake ring 4 disposed at the bottom of the base 1, and the second gas mixing groove 3 is in communication with the air intake ring 4 via a plurality of air guide tubes 5.

[0027] After the air intake ring 4 is connected to the burner base, the gas enters the air intake ring 4 through the burner base, and then enters the first gas mixing tank 2 and the second gas mixing tank 3;

[0028] The surfaces of the first gas mixing tank 2 and the second gas mixing tank 3 are respectively covered with a first fire distribution cover 6 and a second fire distribution cover 7. The first gas mixing tank 2, the second gas mixing tank 3 and the base 1 are respectively made of stainless steel castings. After the three are connected, they are assembled into one by laser welding.

[0029] In one embodiment, the second fire-spreading cover 7 is disc-shaped, and its cross section is a right-angled trapezoid with an open lower end. The outer cylindrical surface of the second fire-spreading cover 7 is provided with a first fire-spraying hole ring 71 and a second fire-spraying hole ring 72 distributed vertically.

[0030] In one embodiment, the first flame-spraying hole ring 71 is located above the second flame-spraying hole ring 72 , and the diameter of the first flame-spraying hole ring 71 is larger than the diameter of the second flame-spraying hole ring 72 .

[0031] In one embodiment, the conduction paths of the first flame injection hole ring 71 and the second flame injection hole ring 72 are arranged in an inclined shape with the inner side lower and the outer side higher.

[0032] In one embodiment, an outer buckle ring 73 is extended downward from the bottom of the outer ring of the second ignition distribution cover 7, and the outer buckle ring 73 extends into the second gas mixing tank 3 and is connected to the base 1; an inner buckle ring 74 is extended downward from the inner ring of the second ignition distribution cover 7, and the inner buckle ring 74 extends into the outer cylindrical surface of the second gas mixing tank 3 and is connected to the base 1.

[0033] In one embodiment, a docking ring 61 extends downward from the bottom of the first ignition distributor cover 6 , and the docking ring 61 is snapped into the inner hole of the first gas mixing tank 2 to dock with it.

[0034] In one embodiment, a conduit 21 extends downward from the bottom of the first gas mixing tank 2 , and the lower opening of the conduit 21 is arranged lower than the lower opening of the air guide pipe 5 .

[0035] The stainless steel precision-cast gas stove distributor of this utility model achieves efficient and uniform distribution of gas and full combustion through a carefully designed structure and material selection. Its working principle is as follows:

[0036] When the gas stove is turned on, gas passes through the burner base and enters the air intake ring 4 at the bottom of the base 1. The air intake ring 4 connects to the burner base, forming a stable gas channel. From the air intake ring 4, the gas enters the first gas mixing tank 2 and the second gas mixing tank 3. The bottom of the first gas mixing tank 2 is directly connected to the air intake ring 4, ensuring smooth gas flow. The second gas mixing tank 3 is connected to the air intake ring 4 via several air guide tubes 5. The design of the air guide tubes 5 ensures that the gas is evenly distributed to the second gas mixing tank 3, avoiding airflow turbulence.

[0037] In the first and second mixing tanks 2 and 3, the gas and air are thoroughly mixed. The concave design of the mixing tanks increases the contact area between the gas and air, promoting improved mixing efficiency. The mixed gas is then introduced into the corresponding combustion area through the mixing tanks.

[0038] The mixed gas enters the combustion zone from the gas mixing tank and is ignited and burned through the flame holes covered by the first flame distribution cover 6 and the second flame distribution cover 7. The first flame distribution cover 6 covers the surface of the first gas mixing tank 2, and the second flame distribution cover 7 covers the surface of the second gas mixing tank 3. The flame holes on the flame distribution cover are scientifically designed to effectively distribute the gas and ensure uniform combustion of the gas.

[0039] The outer cylindrical surface of the second flame distributor cover 7 is provided with a first ring of flame holes 71 and a second ring of flame holes 72, arranged vertically. The first ring of flame holes 71 is positioned above the second ring of flame holes 72, and its diameter is larger than that of the second ring of flame holes 72. This design allows for full combustion of gas at different heights and in different areas, improving combustion efficiency. Furthermore, the conduction paths of the first and second rings of flame holes 71, 72 are arranged in an inclined pattern, with the innermost lower and the outermost higher. This inclined conduction path design further optimizes airflow and enhances combustion stability and uniformity.

[0040] In this case, the first and second mixing tanks 2, 3, and base 1 are all cast from stainless steel. After being separately cast and formed, they are assembled into a single piece via laser welding, ensuring the seal and structural stability of the entire ignition distributor. Furthermore, the second ignition distributor cover 7 has an outer buckle 73 extending from its outer ring base and an inner buckle 74 extending from its inner ring. These buckles extend into the second mixing tank 3 and connect to the base 1. The buckle positions facilitate laser welding, ensuring a tight connection between the ignition distributor cover and the mixing tank, preventing gas leaks.

[0041] Compared to traditional technologies, the stainless steel precision casting process used in this case significantly improves the density and surface finish of the ignition distributor, eliminating the gas leaks and incomplete combustion problems often associated with cast iron gas burners. This high density ensures smooth gas flow, reduces airflow turbulence, and improves combustion efficiency.

[0042] In addition, stainless steel has a high melting point and good heat resistance, and will not deform at high temperatures like aluminum alloy. This characteristic ensures the stability and safety of the ignition divider in high-temperature environments, and avoids safety hazards such as air leakage due to material deformation. At the same time, stainless steel has good oxidation resistance and can maintain the physical properties of the material in high-temperature and high-humidity environments, extending the service life of the ignition divider. Compared with the problem of easy oxidation of copper materials, the use of stainless steel is more reliable, reducing the performance degradation and safety hazards caused by oxidation. In addition, stainless steel has a lower cost than copper, which significantly reduces the manufacturing cost of the ignition divider. By adopting precision casting technology, large-scale production can be achieved, further reducing the unit production cost and improving the market competitiveness of the product.

[0043] In summary, the stainless steel precision-cast gas stove ignition distributor of the present invention realizes efficient and uniform distribution and full combustion of gas through reasonable structural design and precise manufacturing process, thereby ensuring the safety, economy and efficiency of the gas stove.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of this utility model.
