The plurality of first fire holes 105 are arranged on the upper part of the plurality of second fire holes 106. The outer circumference of the flange portion 104 is provided with two rows of fire holes, namely the first fire holes 105 located at the upper part and the second fire holes 106 located at the lower part. Both the first fire holes 105 and the second fire holes 106 can be used for the passage of the mixed gas (gas and air) and realize combustion. The size of the second fire hole 106 located at the lower part is larger than the size of the first fire hole 105 located at the upper part. In the case of combustion, the second fire hole 106 located at the lower part is farther away from the pot body 4. At the same time, because a household frying pan (i.e., Figures 1 to 4 The bottom of the pot body 4) is usually arc-shaped. In the original design, part of the flame at the second fire hole 106 cannot completely contact the bottom of the pot. In order to achieve uniform heating of the pot body 4 and ensure the thermal efficiency of the gas stove and reduce smoke, the size of the second fire hole 106 is increased, thereby increasing the gas output and the height of the flame burning.

[0038] In addition, a first fire hole 105 is arranged between every two adjacent second fire holes 106. That is, the two rows of fire holes are arranged in a staggered manner, so that the flame burns more evenly, thereby ensuring that the pot body 4 is evenly heated.

[0039] Preferably, if Figures 1 to 5As shown, in the embodiment, the first fire hole 105 and the second fire hole 106 are both formed as circular holes; the distance between the center of the adjacent first fire hole 105 and the center of the second fire hole 106 in the height direction is 1mm-1.6mm. After testing and verification, the spacing between the upper and lower rows of fire holes in the range of 1mm-1.6mm can ensure that the flames of the two rows of fire holes evenly contact the bottom of the pot body 4, thereby improving the combustion efficiency.

[0040] Preferably, the distance between the center of the adjacent first ignition hole 105 and the center of the adjacent second ignition hole 106 in the height direction is 1.3 mm, and a height difference of 1.3 mm is the most excellent choice.

[0041] Preferably, if Figures 1 to 5 As shown, in the embodiment, the diameter of the first fire outlet hole 105 is 1.3mm-1.7mm; the diameter of the second fire outlet hole 106 is 2.2mm-2.8mm. After testing and verification, the diameter of the first fire outlet hole 105 in the range of 1.3mm-1.7mm and the diameter of the second fire outlet hole 106 in the range of 2.2mm-2.8mm can ensure that the mixed gas is discharged evenly and has good fluidity during gas discharge, thereby increasing the combustion efficiency. At the same time, the fire outlet holes within the above size range can ensure that the flame has good contact with the bottom of the pot during combustion, so that the flame can reach the bottom of the pot evenly. Here, the larger the diameter of the fire outlet hole, the higher the flame height, and the smaller the diameter, the lower the flame height.

[0042] Preferably, the diameter of the first ignition hole 105 is 1.6 mm, and the diameter of the second ignition hole 106 is 2.5 mm. These two sizes of ignition holes are the best choices.

[0043] Preferably, if Figures 1 to 5 As shown, in the embodiment, the distance between the center of the adjacent first ignition hole 105 and the center of the second ignition hole 106 in the horizontal direction is 1.4mm-1.5mm.

After testing and verification, the center of the adjacent first ignition holes 105 and the second ignition holes 106 with a horizontal spacing within the range of 1.4mm-1.5mm can make the pot body 4 heated evenly, thereby improving the combustion efficiency.

[0044] Preferably, if Figures 1 to 5 As shown, in the embodiment, the outer surface of the flange portion 104 is formed as an arc-shaped surface with an arc. Figures 1 to 4The bottom of the pot body 4) is usually arc-shaped. In the original design, part of the flame at the second fire hole 106 cannot completely contact the bottom of the pot. In order to achieve uniform heating of the pot body 4 and ensure the thermal efficiency of the gas stove and reduce smoke, the outer surface of the flange 104 is designed to be an arc surface to further adapt to household frying pans.

[0045] Preferably, if Figure 4 As shown, the distance between the center of the first fire hole 105 with the above size and structure and the pot bottom can be h2, and the distance between the second fire hole 106 with the above size and structure and the pot body 4 can be h1. Specifically, during use, the height of the flame generated by the first fire hole 105 can be 33mm-37mm, and the height of the flame generated by the second fire hole 106 can be 35mm-39mm, that is, the height of h2 can be 33mm-37mm, and the height of h1 can be 35mm-39mm. The flame within these two ranges can adapt to the pot bottom with an arc, and make the flame fully contact the pot bottom, achieve full combustion, improve combustion efficiency, and avoid smoke generation.

[0046] Preferably, when the size of the first fire outlet hole 105 is 1.6 mm, h2 is 35 mm; when the size of the second fire outlet hole 106 is 2.5 mm, h1 is 37 mm. The flame heights of these two sizes are more suitable for household frying pans.

[0047] Preferably, if Figures 1 to 5 As shown, in the embodiment, the fire cover assembly 1 may include an outer ring fire cover 101 and an inner ring fire cover 102, the inner ring fire cover 102 is arranged inside the outer ring fire cover 101, and the outer ring fire cover 101 may include a main board 103 and a flange portion 104. That is, the above structural improvement is for the outer ring fire cover 101, because the inner ring fire cover 102 usually directly contacts the middle area of ​​the bottom of the pot of a household frying pan, and the flame can directly contact the middle area of ​​the bottom of the pot when burning, so the inner ring fire cover 102 can adopt a fire cover commonly used in the prior art, such as a copper core fire cover, to ensure the adaptability of the assembly with the outer ring fire cover 101.

[0048] Preferably, if Figures 1 to 4 As shown, in the embodiment, the burner structure adapted to a household frying pan can be used to heat the household frying pan (i.e., the pot body 4), the burner structure adapted to a household frying pan is arranged at the bottom of the household frying pan, the inner ring fire cover 102 is arranged at the middle of the bottom of the household frying pan, and the outer ring fire cover 101 is arranged at the side of the bottom of the household frying pan. Different areas of the pot body 4 are heated by different fire covers, so as to improve the combustion efficiency and enhance the user's product experience.

[0049] Preferably, if Figure 1 and Figure 2As shown, in the embodiment, the burner structure adapted for household frying pans may further include a burner body 2, and the fire cover assembly 1 is covered on the burner body 2. The burner body 2 can supply gas to the fire cover assembly 1 and ignite the mixed gas.

The width of the first fire outlet groove 107 in the vertical direction is smaller than the width of the second fire outlet groove 108 in the vertical direction. Since the second fire outlet groove 108 is far away from the bottom of the pot body 4, the opening width of the second fire outlet groove 108 needs to be larger to ensure that the flame generated by the second fire outlet groove 108 can reach the bottom of the pot body 4 at the same time as the flame generated by the first fire outlet groove 107, so as to achieve uniform heating.

[0052] In addition, in the second embodiment, the remaining structures are the same as those in the first embodiment and will not be described in detail here.

[0053] The stove head structure adapted to a household wok improves the structure of the fire cover assembly and adjusts the setting positions of the first fire outlet portion and the second fire outlet portion of the flange portion, thereby adapting to a household wok with an arc at the bottom, thereby achieving full contact between the flame and the bottom of the pot during combustion, improving combustion efficiency, reducing smoke, and improving the user experience.
