Description

Technical Field

[0001] This utility model belongs to the field of stove head technology, specifically relating to a burner stove head structure. Background Technology

[0002] The burner head is a core functional component of a gas stove, and its structural design directly affects the mixing effect of gas and air, combustion stability, and the overall safety and reliability of the product. Traditional burner heads are mainly made by one-piece casting. Although one-piece casting burner heads have strong integrity and good sealing, they have problems such as high mold development costs, complex production processes, large product weight, and are not conducive to lightweight design. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a burner head structure with a reasonable structural design. The burner head frame adopts a three-layer structure of bottom cover plate, middle cover plate and top cover plate. The layered design facilitates assembly and maintenance, and also reduces production costs and process complexity.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A burner head structure includes a burner head frame and an injector tube. The burner head frame includes a bottom cover plate, a middle cover plate and a top cover plate. The middle cover plate is fixedly connected to the bottom cover plate and the top cover plate is fixedly connected to the middle cover plate.

[0006] Furthermore, the bottom cover plate is provided with mounting holes, and the ejector tube is installed in the mounting holes and welded to the bottom cover plate. The ejector tube and the bottom cover plate are connected by fitting through the mounting holes and then fixed by welding to ensure the sealing and stability of the connection.

[0007] Furthermore, the ejector tube and the bottom cover plate are welded together using a full weld connection. This full weld connection creates a highly reliable gas-tight connection, enhancing the sealing and strength of the connection between the ejector tube and the bottom cover plate. This prevents the ejector tube from loosening, deforming, or coming out of the mounting hole, thereby effectively preventing gas leakage and improving the safety of the burner.

[0008] Furthermore, support feet are provided on both sides of the top cover plate, and the support feet are welded and fixed to the top cover plate. The welding and fixing enhances the overall rigidity and stability of the burner head structure. At the same time, the support frame also facilitates the installation and fixing of the burner head, improving the ease of use.

[0009] Furthermore, support frames are provided on both sides of the top cover plate. The support frames extend downward from both sides of the top cover plate and are integrally molded with the top cover plate. By extending downward to form a continuous structure, the top cover plate and the support frames form a rigid whole, which enhances the overall structural strength and stability. The integral molding design also facilitates processing and manufacturing.

[0010] Furthermore, the middle cover plate and the bottom cover plate are fastened together. The side edge of the bottom cover plate extends upward with a protruding section. The top of the protruding section bends towards the inside of the bottom cover plate to form an upper limit section. The upper limit section, the protruding section, and the bottom cover plate form a limiting slot. The side edge of the middle cover plate extends outward to form a flat insertion section. The flat insertion section is locked in the limiting slot, realizing the fastening and fixing between the middle cover plate and the bottom cover plate. The structural design is ingenious and reasonable. The flat insertion section is locked in the limiting slot to form quick positioning and mechanical interlock, realizing a stable fastening between the middle cover plate and the bottom cover plate, improving the stability and reliability of the connection, preventing loosening, and facilitating actual assembly and disassembly.

[0011] Furthermore, the top cover plate and the middle cover plate are tightly fitted and fixed together. The middle cover plate is provided with mounting part one, and the top cover plate is provided with mounting part two. Both mounting parts one and two are provided with through holes for the ejector tube to pass through. The tight fit between mounting parts one and two is ingeniously designed. The interference fit between mounting parts one and two achieves a gapless connection, which can ensure a stable connection between the middle cover plate and the top cover plate, enhance the rigidity and stability of the overall structure, avoid abnormal noise and shaking caused by gaps, and improve the sealing reliability and the safety of the furnace head. Moreover, the assembly of the middle cover plate and the top cover plate does not require cumbersome steps such as screw tightening, which improves the assembly efficiency.

[0012] Furthermore, mounting part one is tightly fitted into mounting part two. Mounting part one includes a first insertion ring segment and a second insertion ring segment, and mounting part two includes a first limiting ring segment and a second limiting ring segment. The first insertion ring segment is tightly fitted into the first limiting ring segment, and the second insertion ring segment is tightly fitted into the first limiting ring segment. The design of the tight fitting between the insertion ring segment and the limiting ring segment achieves a stable connection between mounting part one and mounting part two, improves the tightness and reliability of the connection, and this segmented insertion method also facilitates actual assembly and adjustment.

[0013] Furthermore, the first limiting ring segment is fixedly connected to the top cover plate, and the second limiting ring segment is fixedly connected to the first limiting ring segment. The inner diameter of the second limiting ring segment is smaller than that of the first limiting ring segment, which forms a stepped groove in the through hole of the second mounting part. The outer diameter of the first insertion ring segment is larger than that of the second insertion ring segment, which forms a step on the outside of the second mounting part. The step is tightly fitted into the stepped groove. The structural design is ingenious and reasonable. Through this cooperation between the step and the stepped groove, the precise positioning between the middle cover plate and the top cover plate is achieved, which further enhances the connection stability between the first mounting part and the second mounting part, and also facilitates alignment and fixation during assembly.

[0014] Furthermore, an arched boss is provided on the intermediate cover plate, which smoothly transitions to the side of the insertion ring section one. This smooth transition connection can avoid stress concentration and improve structural reliability. When the top cover plate and the intermediate cover plate are tightly fitted and fixed, the top cover plate abuts and is limited on the top surface of the arched boss, which improves the connection stability between the top cover plate and the intermediate cover plate. The arched boss supports and lifts the top cover plate to prevent deformation, making the overall structure more stable and extending the service life of the furnace head structure.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This utility model is reasonably designed and highly practical. The burner head frame and injector tube are made of 201 stainless steel. The burner head frame adopts a three-layer structure of bottom cover plate, middle cover plate, and top cover plate, and the components are stably connected through snap-fit ​​and tight-fitting fixing methods. The layered design facilitates assembly and maintenance, and also reduces production costs and process complexity. Furthermore, the various parts of the burner head frame are assembled and connected through snap-fitting, tight-fitting, and welding methods, avoiding the risk of screws loosening or corroding at high temperatures, greatly improving connection reliability and sealing. In this application, the injector tube and bottom cover plate are matched and inserted through mounting holes and then fixed by welding, ensuring the sealing and stability of the connection. The welding is a full weld connection, which can form a highly reliable gas-tight connection, enhancing the sealing and strength of the connection between the injector tube and the bottom cover plate, effectively preventing gas leakage and improving the safety of the burner.

Detailed Implementation

[0032] like Figures 1 to 12 As shown in Embodiment 1 of this utility model, a burner head structure includes a burner head frame 1 and an injector tube 2. The burner head frame 1 includes a bottom cover plate 3, a middle cover plate 4, and a top cover plate 5. The middle cover plate 4 is fixedly connected to the bottom cover plate 3, and the top cover plate 5 is fixedly connected to the middle cover plate 4. The bottom cover plate 3 is provided with a mounting hole 6, and the injector tube 2 is matched and installed in the mounting hole 6 and welded to the bottom cover plate 3. The welding method of the injector tube 2 and the bottom cover plate 3 is a full weld connection. The full weld connection forms a highly reliable gas-tight connection, enhancing the sealing and strength of the connection between the injector tube 2 and the bottom cover plate 3, preventing the injector tube 2 from loosening, deforming, or falling out of the mounting hole 6, thereby effectively preventing gas leakage and improving the safety of the burner.

[0033] Support feet 7 are provided on both sides of the top cover plate 5. The support feet 7 are welded and fixed to the top cover plate 5. The welding and fixing enhances the overall rigidity and stability of the burner head structure. At the same time, the support frame facilitates the installation and fixing of the burner head, improving the ease of use.

[0034] The middle cover plate 4 is fastened to the bottom cover plate 3. The bottom cover plate 3 has a raised section 8 extending upward from its side edge. The top of the raised section 8 is bent towards the inside of the bottom cover plate 3 to form an upper limit section 9. The upper limit section 9, the raised section 8, and the bottom cover plate 3 form a limiting slot 10. The middle cover plate 4 extends outward from its side edge to form a flat insertion section 11. The flat insertion section 11 is locked in the limiting slot 10, thus achieving the fastening and fixing between the middle cover plate 4 and the bottom cover plate 3. The structure is ingenious and reasonable. The flat insertion section 11 is locked in the limiting slot 10 to form quick positioning and mechanical interlock, achieving a stable fastening between the middle cover plate 4 and the bottom cover plate 3, improving the stability and reliability of the connection, preventing loosening, and facilitating actual assembly and disassembly.

[0035] The top cover plate 5 and the intermediate cover plate 4 are tightly fitted and fixed together. The intermediate cover plate 4 is provided with a mounting part 12, and the top cover plate 5 is provided with a mounting part 23. Both the mounting part 12 and the mounting part 23 are provided with through holes 14 for the ejector tube 2 to pass through. The mounting part 12 and the mounting part 23 are tightly fitted and fixed together. The design is ingenious. The interference fit between the mounting part 12 and the mounting part 23 achieves a gapless connection, which can ensure a stable connection between the intermediate cover plate 4 and the top cover plate 5, enhance the rigidity and stability of the overall structure, avoid abnormal noise and shaking caused by gaps, and improve the sealing reliability and the safety of the furnace head. Moreover, the assembly of the intermediate cover plate 4 and the top cover plate 5 does not require cumbersome steps such as screw tightening, which improves the assembly efficiency.

[0036] Mounting part 12 is tightly fitted into mounting part 2 13. Mounting part 12 includes a first insertion ring segment 15 and a second insertion ring segment 16. Mounting part 2 13 includes a first limiting ring segment 17 and a second limiting ring segment 18. The first insertion ring segment 15 is tightly fitted into the first limiting ring segment 17, and the second insertion ring segment 16 is tightly fitted into the first limiting ring segment 17. The design of the tight fitting between the insertion ring segment and the limiting ring segment achieves a stable connection between mounting part 12 and mounting part 2 13, improves the tightness and reliability of the connection, and this segmented insertion method also facilitates actual assembly and adjustment.

[0037] Limiting ring segment 17 is fixedly connected to the top cover plate 5, and limiting ring segment 2 18 is fixedly connected to limiting ring segment 17. The inner diameter of limiting ring segment 2 18 is smaller than the inner diameter of limiting ring segment 17, so that a stepped groove is formed in the through hole 14 of mounting part 2 13. The outer diameter of insertion ring segment 15 is larger than the outer diameter of insertion ring segment 2 16, so that a step is formed on the outside of mounting part 2 13. The step is tightly fitted into the stepped groove. The structural design is ingenious and reasonable. Through this cooperation of step and stepped groove, the precise positioning between the intermediate cover plate 4 and the top cover plate 5 is achieved, which further enhances the connection stability between mounting part 12 and mounting part 2 13, and also facilitates alignment and fixation during assembly.

[0038] An arched boss 19 is provided on the intermediate cover plate 4. The arched boss 19 is smoothly connected to the side of the insertion ring section 15. The smooth transition connection can avoid stress concentration and improve structural reliability. When the top cover plate 5 and the intermediate cover plate 4 are tightly fitted and fixed, the top cover plate 5 abuts against and is limited on the top surface of the arched boss 19, which improves the connection stability between the top cover plate 5 and the intermediate cover plate 4. The arched boss 19 supports and lifts the top cover plate 5 to prevent deformation, making the overall structure more stable and extending the service life of the furnace head structure.

[0039] like Figure 13 As shown, this is Embodiment 2 of the present invention. Based on Embodiment 1, the connection relationship between the support foot 7 and the top cover plate 5 has been adjusted. Support frames 7 are provided on both sides of the top cover plate 5, extending downwards from both sides of the top cover plate 5. The support frames 7 and the top cover plate 5 are integrally molded, forming a continuous structure by extending downwards, thus making the top cover plate 5 and the support frames 7 a rigid whole, enhancing the overall structural strength and stability. The integral molding design also facilitates processing and manufacturing.

[0040] This utility model is reasonably designed and highly practical. The burner head frame 1 and injector tube 2 are both made of 201 stainless steel. The burner head frame 1 adopts a three-layer split structure: a bottom cover plate 3, a middle cover plate 4, and a top cover plate 5. The components are securely connected through snap-fit ​​and tight-fitting methods. This layered design facilitates assembly and maintenance, and reduces production costs and process complexity. Furthermore, the various parts of the burner head frame 1 are assembled and connected through snap-fit, tight-fitting, and welding methods, avoiding the risk of screws loosening or corroding at high temperatures, greatly improving connection reliability and sealing. In this application, the injector tube 2 and the bottom cover plate 3 are matched and inserted through mounting holes 6 and then fixed by welding, ensuring the sealing and stability of the connection. The welding is a full weld connection, forming a highly reliable gas-tight connection, enhancing the sealing and strength of the connection between the injector tube 2 and the bottom cover plate 3, effectively preventing gas leakage and improving burner safety.
