[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a high-power burner head, such as... Figure 1-3 As shown, the device includes an inner ring body 100 and an outer ring body 200, with the outer ring body 200 surrounding the inner ring body 100. The inner ring body 100 and the outer ring body 200 can be coaxially arranged. The top surface of the inner ring body 100 is provided with a first inner ring flame hole 101 and a second inner ring flame hole 102, both arranged in a circle relative to the axis of the inner ring body 100. The first inner ring flame hole 101 is located inside the second inner ring flame hole 102, meaning that in the radial direction of the inner ring body 100, the first inner ring flame hole 101 is closer to the axis of the inner ring body 100 than the second inner ring flame hole 102. Both the first inner ring flame hole 101 and the second inner ring flame hole 102 can eject combustion gas, thus forming two rings of flame within the inner ring.

[0026] The top surface of the outer ring body 200 is provided with a first outer ring flame hole 201 and a second outer ring flame hole 202, both of which are circularly distributed relative to the axis of the outer ring body 200. The first outer ring flame hole 201 is located inside the second outer ring flame hole 202, that is, in the radial direction of the outer ring body 200, the first outer ring flame hole 201 is closer to the axis of the outer ring body 200 than the second outer ring flame hole 202. Both the first outer ring flame hole 201 and the second outer ring flame hole 202 can eject combustion gas, thereby forming two rings of flame in the outer ring. Thus, a total of four rings of flame can be formed.

[0027] The outer surface of the inner ring 100 is provided with an ignition hole 103 facing outward, and the top surface of the outer ring 200 is also provided with a ring of first ignition holes 203. The first ignition holes 203 are distributed in a circle relative to the axis of the outer ring 200. The first ignition holes 203 are located inside the first outer ring ignition hole 201. In the radial direction of the outer ring 200, the first ignition holes 203 are closer to the axis of the outer ring 200 than the first outer ring ignition hole 201.

[0028] When a user wants to switch from low flame mode to high flame mode, that is, when they want the outer ring flame to ignite as well, the flame ejected outward from the ignition hole 103 can ignite the gas ejected from the first ignition hole 203. The flame formed by the first ignition hole 203 then sequentially ignites the gas ejected from the first outer ring flame hole 201 and the second outer ring flame hole 202, thus successfully transferring the flame from the inner ring to the outer ring, improving the user experience.

[0029] In some embodiments, the ignition hole 103 is inclined, and its height gradually increases in the radial and outward direction along the inner ring 100. The ignition hole 103 will inject gas obliquely outward, and correspondingly, the flame will also be ejected obliquely outward, with the flame closer to the top of the first ignition hole 203, thereby making it easier to ignite the gas ejected from the first ignition hole 203.

[0030] Furthermore, the ignition hole 103 is angled at 45° to the horizontal direction. It has been verified that this angle makes the gas ejected from the first ignition hole 203 have the highest probability of being ignited and the highest ignition success rate.

[0031] In some embodiments, the diameter of the first ignition hole 203 is 2.1 mm, and the diameter of the ignition hole 103 is 3.0 mm; the distance from the first ignition hole 203 to the first outer ring ignition hole 201 in the radial direction of the outer ring body 200 is 5.5-6.5 mm. In this embodiment, the larger diameter of the ignition hole 103 results in a larger flame, making it easier to ignite the gas ejected from the first ignition hole 203. The distance from the first ignition hole 203 to the first outer ring ignition hole 201 is sufficient to allow the flame of the first ignition hole 203 to ignite the gas ejected from the first outer ring ignition hole 201, while also minimizing the impact on the flame of the first outer ring ignition hole 201.

[0032] The optimal distance between the first ignition hole 203 and the first outer ring ignition hole 201 is 6.0 mm.

[0033] In the above embodiments, although the inner ring flame can be successfully transmitted to the outer ring by adding the ignition hole 103 and the first ignition hole 203, the time required from the start of flame transmission to the outer ring until both the first outer ring flame hole 201 and the second outer ring flame hole 202 are ignited is relatively long due to the large distance between them, which affects the user's cooking efficiency.

[0034] In this embodiment, a second ignition hole 204 is also provided on the top surface of the outer ring body 200. The second ignition holes 204 are distributed in a circle relative to the axis of the outer ring body 200. The second ignition holes 204 are located outside the first outer ring ignition hole 201 and inside the second outer ring ignition hole 202, that is, in the radial direction of the outer ring body 200. The second ignition holes 204 are farther away from the axis of the outer ring body 200 than the first outer ring ignition hole 201, and closer to the axis of the outer ring body 200 than the second outer ring ignition hole 202.

[0035] When the user wants to switch from low heat to high heat, the flame ejected from the ignition hole 103 ignites the gas emitted from the first ignition hole 203. The flame from the first ignition hole 203 then ignites the gas emitted from the first outer ring flame hole 201. The flame from the first outer ring flame hole 201 then ignites the gas emitted from the second ignition hole 204. Finally, the flame from the second ignition hole 204 ignites the gas emitted from the second outer ring flame hole 202, thus successfully igniting the gas emitted from both the first and second outer ring flame holes 201 and 202. This structure shortens the time required from the start of flame transmission to the outer ring until both the first and second outer ring flame holes 201 and 202 are ignited, improving the user's cooking efficiency.

[0036] In some embodiments, the diameter of the second ignition hole 204 is 2.1 mm; the distance from the second ignition hole 204 to the second outer ring ignition hole 202 in the radial direction of the outer ring body 200 is 5.5-6.5 mm. The distance between the second ignition hole 204 and the second outer ring ignition hole 202 is sufficient to allow the flame of the second ignition hole 204 to ignite the gas ejected from the second outer ring ignition hole 202, while also minimizing the impact on the flame of the second outer ring ignition hole 202.

[0037] The optimal distance between the second ignition hole 204 and the second outer ring ignition hole 202 is 6.0 mm.

[0038] In some embodiments, the diameters of the first inner ring flame hole 101, the second inner ring flame hole 102, and the first outer ring flame hole 201 are all 2.8 mm, and the diameter of the second outer ring flame hole 202 is 3.0 mm. Compared with traditional cast iron direct-fired furnace heads, the diameters of the first inner ring flame hole 101, the second inner ring flame hole 102, the first outer ring flame hole 201, and the second outer ring flame hole 202 are all increased. This increases the combustion area, allows the fuel gas to be fully combusted, solves the problem of yellow flame, and reduces the generation of harmful gases.

[0039] In some embodiments, the bottom of the inner ring 100 is provided with a first support foot 310, and the bottom of the outer ring 200 is provided with a second support foot 320. The first support foot 310 and the second support foot 320 can stably support the front side of the entire burner head, so that the burner head remains stable.

[0040] The second support foot 320 can be provided in two parts, and is symmetrically distributed relative to the first support foot 310 to form an isosceles triangle position distribution, which has higher stability.

[0041] In some embodiments, the inner ring body 100 includes a first inner ring protrusion 110 and a second inner ring protrusion 120 located on its top surface. The first inner ring protrusion 110 and the second inner ring protrusion 120 are both circularly distributed relative to the axis of the inner ring body 100, and in the radial direction of the inner ring body 100, the first inner ring protrusion 110 is located inside the second inner ring protrusion 120. Each first inner ring protrusion 110 is provided with a first inner ring fire hole 101, and each second inner ring protrusion 120 is provided with a second inner ring fire hole 102.

[0042] The outer ring body 200 includes a first outer ring protrusion 210 and a second outer ring protrusion 220 located on its top surface. The first outer ring protrusion 210 and the second outer ring protrusion 220 are both circularly distributed relative to the outer ring body 200, and in the radial direction of the outer ring body 200, the first outer ring protrusion 210 is located inside the second outer ring protrusion 220. Each first outer ring protrusion 210 is provided with a first outer ring fire hole 201, and each second outer ring protrusion 220 is provided with a second outer ring fire hole 202.

[0043] In some embodiments, the first inner ring flame hole 101, the second inner ring flame hole 102, the first outer ring flame hole 201, the second outer ring flame hole 202, the first ignition hole 203, and the second ignition hole 204 of the above embodiments can be evenly distributed relative to the axis of the inner ring body 100 so as to make the flame uniform.

[0044] In some embodiments, an inner ring ejector tube 130 is connected to the bottom of the inner ring body 100, and an outer ring ejector tube 230 is connected to the bottom of the outer ring body 200. The inner ring ejector tube 130 is used to eject gas into the inner ring mixing chamber within the inner ring body 100, and the outer ring ejector tube 230 is used to eject gas into the outer ring mixing chamber within the outer ring body 200.
