[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] A burner includes a base 1, a middle seat 2 mounted on the base 1, an outer ring flame cap 3 mounted on the base 1 and the middle seat 2, and an inner ring flame cap 4 mounted on the middle seat 2.

[0027] The base 1 includes an outer bottom ring 11, an inner bottom ring 12, and a chassis 13 connecting the outer bottom ring 11 and the inner bottom ring 12;

[0028] The middle seat 2 includes an outer ring 21, an inner ring 22, and a middle plate 23 connecting the outer ring 21 and the inner ring 22;

[0029] An outer ring cavity 14 is formed between the middle outer ring 21 and the bottom outer ring 11, an outer air intake cavity 15 is formed between the middle inner ring 22 and the bottom inner ring 12, and a diffuser cavity 16 is provided between the chassis 13 and the middle plate 23. The diffuser cavity 16 is fan-shaped, and multiple diffuser cavities 16 are evenly spaced around the bottom inner ring 12.

[0030] This invention provides a burner in which a fan-shaped diffuser cavity with uniform circumferential distribution can effectively guide the gas from the outer air intake cavity to the outer annular cavity for uniform diffusion and pressure balance, thereby improving the mixing effect and combustion stability.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the middle plate 23 includes a plate surface 231 and an enlarged portion 232 that gradually slopes upward from the plate surface 231 toward the outer ring 21. The enlarged portion 232 is disposed corresponding to the diffuser cavity 16, such that the depth of the diffuser cavity 16 gradually increases along the direction from the outer air intake cavity 15 toward the outer ring cavity 14. The diffuser cavity 16 with its gradually increasing depth guides the airflow smoothly toward the outer ring cavity 14 and promotes more thorough mixing of the fuel gas and air during the diffusion process.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, a connecting platform 17 protrudes from the base 1 between the two diffusion cavities 16. A hollow platform 18 is provided on the connecting platform 17, and a connecting port 24 is provided between the outer ring 21 and the disk surface 231. The connecting port 24 is inserted into the hollow platform 18. The insertion and engagement of the hollow platform 18 and the connecting port 24 achieves a stable connection and accurate positioning of the base 1 and the middle base 2 at a specific location (between the diffusion cavities 16). This also helps to reduce weight and save materials, aligning with the spacing of the diffusion cavities.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting platform 17 is provided with a positioning hole 19, and the outer ring 21 is provided with a positioning post 25 that engages with the positioning hole 19. The engagement of the positioning post 25 with the positioning hole 19 provides precise circumferential positioning, preventing relative rotation between the base 1 and the middle seat 2, and ensuring the alignment of circumferential features such as the diffusion cavity 16.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer ring flame cap 3 includes a first cap ring 31 and a second cap ring 32, and a cap surface 33 connecting the first cap ring 31 and the second cap ring 32. The cap surface 33 is provided with positive triangular surfaces 34 sequentially connected around the second cap ring 32, and the apex of the positive triangular surfaces 34 gradually slopes upward toward the first cap ring 31. The upwardly sloped positive triangular surfaces 34 form an inner cavity at a specific angle, which helps to guide the flame upward and diffuse toward the first cap ring 31, optimizing the outer ring flame shape and heat distribution.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the cover surface 33 is provided with inverted triangular surfaces 35 sequentially connected around the first cover ring 31, the apex of the inverted triangular surfaces 35 extending towards the connection between the two upright triangular surfaces 34. The inverted triangular surfaces help to form a stable supporting flame in this area, improving the overall flame continuity and wind resistance.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer ring burner cap 3 is mounted on the bottom outer ring 11 and the middle outer ring 21 to cover the outer ring cavity 14. This ensures that the outer ring burner cap 3 securely covers the outer ring cavity 14, forming a sealed combustion zone, through which the fuel mixture is ejected and burned via the burner holes.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the middle seat 2 also includes a first inner ring 26 and a second inner ring 27. An inner air intake chamber 28 is formed between the middle inner ring 22 and the second inner ring 27. An inner ring cavity 29 is provided between the first inner ring 26 and the second inner ring 27. The inner ring burner cap 4 is installed on the first inner ring 26 and the second inner ring 27 to cover the inner ring cavity 29. The independent design of the inner air intake chamber 28 and the inner ring cavity 29 separates the gas supply path of the inner ring from that of the outer ring, allowing for independent control and optimization of the combustion state of the inner ring (center burner).

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the middle plate 23 is provided with an air inlet 233 connecting the inner annular cavity 29 and the inner air intake cavity 28. The air inlet 233 is fan-shaped and evenly distributed around the second inner ring 27. The fan-shaped and evenly distributed air inlet 233 ensures that the combustion gas can enter the inner annular cavity 29 evenly and stably from the inner air intake cavity 28, providing a uniform gas mixture source for the inner annular flame.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the inner annular cavity 29 includes a bottom surface 71 surrounding the second inner ring 27, and an inclined surface 72 that gradually slopes upward from the bottom surface 71 toward the first inner ring 26. The air inlet 233 is located on the bottom surface 71 and the inclined surface 72, and is in close contact with the second inner ring 27. The air inlet 233 being in close contact with the second inner ring 27 and distributed on the bottom surface 71 and the inclined surface 72 shortens the path for the combustion gas to enter the inner annular cavity 29; the structure of the inclined surface 72 helps to guide the airflow smoothly upward into the combustion area of ​​the inner annular cavity 29, improving the inner annular combustion efficiency and response speed.

[0040] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
