The provision of the mixing channel provides an initial mixing place for the gas and the air, and the air and the gas begin to contact and mix in this channel space. Due to the high-speed flow of the gas and the involvement of the air, a certain degree of turbulence is formed, so that the gas and the air can more fully penetrate and mix with each other, creating good conditions for subsequent full combustion in the combustion chamber; at the same time, the mixing channel provides a margin for the thermal expansion of the components to avoid excessive stress between the components due to thermal expansion, thereby preventing deformation, damage or affecting the normal supply of gas.

During the cooking process, when the mixed gas of gas and air is introduced into the outer ring fire groove 11 from the outer ring gas inlet channel 14 and burns, and the mixed gas of gas and air is introduced into the inner ring fire groove 12 from the inner ring gas inlet channel 15 and burns, air can be supplemented from the gas supplementing channel to make the gas in the outer ring fire groove 11 and the inner ring fire groove 12 fully burn, so as to improve the problem that in the prior art, when the stir-frying operation is performed, there is no additional air to supplement inward, the gas is sufficient, but the air is insufficient, and the burning is insufficient. At the same time, when the gas is supplemented into the center fire groove 13 through the center gas inlet channel 16 to perform the stir-frying operation, the air supplemented from the gas supplementing channel can also make the gas in the center fire groove 13 fully burn.
[0042] Among them, since the first ring wall a, the second ring wall b, the third ring wall c and the fourth ring wall d can all be circular ring structures, and the inner diameters of the four are successively reduced and concentrically arranged, the area of the gas supplementing channel surrounded by the second ring wall b and the third ring wall c is greater than the area of the inner ring fire groove 12 and the center fire groove 13 together, and the gas supplementing channel is arranged outside the inner ring fire groove 12 and the center fire groove 13, so as to ensure that the gas in the inner ring fire groove 12 and the center fire groove 13 is fully burned.

[0046] The burner of the utility model, please refer to Figures 4 to 6 The outer ring air inlet channel 14, the central air inlet channel 16 and the inner ring air inlet channel 15 are arranged in sequence and at intervals, the central air inlet channel 16 is located between the outer ring air inlet channel 14 and the inner ring air inlet channel 15, the outer ring air inlet channel 14 extends from the first bottom surface e to the second bottom surface f, and the air outlet end penetrates through the second ring wall b; the inner ring air inlet channel 15 extends from the first bottom surface e to the second bottom surface f, and the air outlet end penetrates through the third ring wall c; the central air inlet channel 16 extends from the first bottom surface e to the second bottom surface f, and the air outlet end penetrates through the fourth ring wall d.
[0047] In the embodiment, the outer ring air inlet channel 14, the center air inlet channel 16 and the inner ring air inlet channel 15 are simultaneously connected to the second ring wall b and the third ring wall c, and the distance between the outer ring air inlet channel 14 and the center air inlet channel 16 is equal to the distance between the inner ring air inlet channel 15 and the center air inlet channel 16, so as to balance the connection and ensure the structural stability of the distributor 1. The outer ring air inlet channel 14, the inner ring air inlet channel 15 and the center air inlet channel 16 are simultaneously connected to the first bottom surface e and the second bottom surface f, so as to ensure the structural stability between the first bottom surface e and the second bottom surface f.
[0048] During the cooking process, the outer ring air inlet channel 14 guides the mixed gas of air and gas from the through opening of the side wall of the second ring wall b into the outer ring fire groove 11 between the second ring wall b and the first ring wall a, the inner ring air inlet channel 15 guides the mixed gas of air and gas from the through opening of the side wall of the third ring wall c into the inner ring fire groove 12 formed between the third ring wall c and the fourth ring wall d, and the center air inlet channel 16 guides the mixed gas of air and gas from the through opening of the side wall of the fourth ring wall d into the center fire groove 13 formed around the fourth ring wall d.
[0049] Based on the above embodiment, please refer to Figure 4 and Figure 5 The inner diameter of the gas outlet end of the outer ring air inlet channel 14 gradually increases, the inner diameter of the gas outlet end of the inner ring air inlet channel 15 gradually increases, and the inner diameter of the gas outlet end of the center air inlet channel 16 gradually increases, so as to reduce the resistance when the gas is discharged, reduce the exhaust back pressure, and make the gas discharge speed relatively stable and moderate, reduce the risk of backfire, the larger diameter of the gas outlet end can make the discharged gas flow more stable, reduce the fluctuation and turbulence of the gas flow, which is beneficial to the stability of the subsequent combustion process, makes the flame more stable, the combustion more uniform, and reduces the problems of incomplete combustion, flame flickering and the like caused by unstable gas flow.
[0050] The burner of the utility model, please refer to Figure 4 The part of the first bottom surface e which is aligned with the gas outlet end of the outer ring air inlet channel 14 is sunken downward to form a gas sink e1, and the gas outlet end of the outer ring air inlet channel 14 is aligned with the gas sink e1.
[0051] During the cooking process, the mixed gas of air and fuel gas enters into the outer ring fire groove 11 from the outer ring air inlet channel 14, and the opposite air sink groove e1 can guide the air flow to flow downward, so that the air flow forms a certain disturbance and backflow at the air sink groove e1, thereby promoting the more sufficient mixing of the fuel gas and the air, creating conditions for more complete combustion, improving the combustion efficiency, releasing more heat by combustion, and ensuring that the flame can remain stable under various working conditions, preventing the phenomenon of flickering, jumping or even extinguishing of the flame. In addition, during the combustion process, the fuel gas may carry some impurities, and the high-temperature gas generated by combustion may form condensate during the cooling process. The air sink groove e1 is located at the bottom of the outer ring fire groove 11 and can collect these impurities and condensate, preventing them from flowing around in the outer ring fire groove 11, avoiding interference with the combustion process, and preventing the impurities and condensate from causing corrosion, blockage and other problems to the outer ring fire groove 11, thereby ensuring the normal operation of the system.

[0053] The extension 151 of the inner ring air inlet channel 15 is connected to the second ring wall b to form a sealed structure. The side wall of the inner ring air inlet channel 15 forms an opening through the third ring wall c to guide the mixed gas of air and fuel gas into the inner ring fire groove 12. On the basis of gradually increasing the inner diameter of the extension 151 to relatively stabilize and moderate the gas discharge speed, during the cooking process, the end of the inner ring air inlet channel 15 is sealed so that the air flow can only flow out from the side wall opening. When the air flow flows in the inner ring air inlet channel 15 to the sealing portion, a certain turbulence is generated, and when the air flow flows out from the side wall opening, it can better interact with the gas in the inner ring fire groove 12, further promoting the mixing of the fuel gas and the air, making the combustion more complete, and reducing the generation of incomplete combustion products.

[0060] When installing the burner head 2, the third support column 25 is supported in the shell of the stove. The third support column 25 is distributed with at least three to ensure stable installation of the burner head 2.
[0061] Please refer to Figures 1 to 3The burner further comprises an outer ring fire cover 3 and an inner ring fire cover 4, the outer ring fire cover 3 is arranged on the outer ring fire groove 11, the outer ring fire cover 3 is provided with an outer ring fire hole 31, the inner ring fire cover 4 covers the inner ring fire groove 12 and the center fire groove 13 at the same time, the side surface of the inner ring fire cover 4 is provided with an inner ring fire hole 41, and the top surface of the inner ring fire cover 4 is further provided with a center fire hole 42 which is aligned with the center fire groove 13.
[0062] During the cooking process, the outer ring fire cover 3 and the inner ring fire cover 4 cooperate with the outer ring fire groove 11, the inner ring fire groove 12 and the center fire groove 13 at different positions to form three different flame areas of the outer ring, the inner ring and the center. The size and intensity of the flame in different areas can be controlled according to actual needs to realize fine adjustment of combustion. For example, during cooking, slow stewing can only use the outer ring fire groove 11 and / or the inner ring fire groove 12 to output a small flame through the outer ring fire hole 31 and / or the inner ring fire hole 41; when strong frying is needed, the outer ring fire groove 11, the inner ring fire groove 12 and the center fire groove 13 can be opened at the same time to output a larger and more intense flame through the outer ring fire hole 31, the inner ring fire hole 41 and the center fire hole 42. The outer ring fire groove 11, the inner ring fire groove 12 and the center fire groove 13 cooperate with the corresponding fire cover and fire hole to make the heat more evenly distributed in the area above the burner. The outer ring flame can cover a larger area, and plays a role in auxiliary heating and heat balance for the inner ring and center areas, avoiding the situation that the center is overheated while the edge temperature is insufficient, so that the heated object can obtain relatively uniform heat on the whole surface, improving the heating quality and efficiency.
[0063] The outer ring fire cover 3 and the inner ring fire cover 4 limit the flame within a specific fire groove and fire hole range, effectively preventing the flame from spreading and running out at will, and reducing the risk of fire caused by the flame contacting surrounding flammable materials. Especially in the kitchen and other environments, there may be various flammable materials around, and this design can ensure the safety of the use process. At the same time, the outer ring fire groove 11, the inner ring fire groove 12 and the center fire groove 13, the outer ring fire cover 3 and the inner ring fire cover 4 work together to form a stable combustion system. When the combustion state of a certain fire groove or fire hole is disturbed by external factors, the flame of other fire grooves and fire holes can play a certain compensation and stabilizing role to maintain the stability of the whole combustion process, ensuring that the burner can continuously and stably output heat, improving the reliability and operating efficiency of the burner.
[0064] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement or improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
