Further, when the stir-frying is needed, the gas can be introduced into the center channel 14 through the gas pipe, so that the gas burns in the center channel 14 to form a center fire, and the center fire burns inside the inner ring fire. In this way, during the cooking process, the three gas passages can be formed by the simultaneous gas supply of the outer ring ejection seat 21, the inner ring ejection seat 22 and the center ejection seat 23, which can ensure sufficient gas supply during stir-frying, and the downward through opening of the air supplement groove 12 and the center channel 14 can simultaneously supplement the air for the gas burning in the outer ring fire groove 11 and the inner ring fire groove 13, and the gas introduced into the center channel 14 by the center ejection seat 23 can enter the center channel 14 with the air in the air supplement gap, so that the supplemented gas and air can be fully mixed to ensure sufficient gas burning during stir-frying.

[0037] In the embodiment, the outer ring fire groove 11, the air supplement groove 12, the inner ring fire groove 13 and the center channel 14 are arranged in concentric circles, and the inner diameters of the four are sequentially reduced, and the air supplement groove 12 is arranged around the inner ring fire groove 13 and the center channel 14, and during the cooking process, the air is continuously supplemented from the air supplement groove 12, which can ensure that the gas in the outer ring fire groove 11 and the inner ring fire groove 13 is fully burned, and at the same time, the air is continuously supplemented from the center channel 14, which can ensure that the gas in the center channel 14 is fully burned.

[0038] The burner of the utility model, please refer to Figure 2 and Figure 5 The bottom surface of the fire divider 1 is provided with a first support column 15, and the upper surface of the burner 2 is provided with a second support column 24, when the fire divider 1 is connected with the burner 2, the first support column 15 is supported on the second support column 24, and the lower surface of the fire divider 1 and the upper surface of the burner 2 form an air supplement gap which is communicated with the air supplement groove 12.

[0039] When the fire divider 1 is installed on the burner 2, the corresponding first support column 15 is supported on the second support column 24, so that the fire divider 1 is stably installed, and at the same time, the lower surface of the fire divider 1 and the upper surface of the burner 2 form an air supplement gap which is communicated with the air supplement groove 12. The air supplement groove 12 and the center channel 14 which all penetrate the bottom surface of the fire divider 1 are all downwardly communicated with the air supplement gap.

[0040] During the cooking process, the central passage 14 penetrates the bottom surface of the fire distributor 1, and air enters the air supplementing groove 12 and the central passage 14 through the air supplementing gap between the lower surface of the fire distributor 1 and the upper surface of the burner 2 to supplement air for the gas combustion, and during the wok-searing operation, the gas pipe of the stove supplies gas into the central passage 14, and when the gas enters the central passage 14, the air in the air supplementing gap enters the central passage 14, so that the supplemented gas and air are fully mixed, which can ensure that the gas is fully combusted during wok-searing.

[0041] In the drawings, the first support columns 15 and the second support columns 24 are only shown in two groups and are symmetrically distributed with the center of the burner 2.

[0042] The burner of the utility model, please refer to Figure 3 and Figure 4 The fire distributor 1 is provided with an outer ring air inlet passage 16 and an inner ring air inlet passage 17, the air inlet end of the outer ring air inlet passage 16 is opposite to the air outlet end of the outer ring ejection seat 21, the air outlet end of the outer ring air inlet passage 16 is communicated with the outer ring fire groove 11, and the air inlet end of the inner ring air inlet passage 17 is opposite to the air outlet end of the inner ring ejection seat 22, and the air outlet end of the inner ring air inlet passage 17 is communicated with the inner ring fire groove 13.

[0043] In the embodiment, the air inlet end of the outer ring air inlet passage 16 is opposite to the air outlet end of the outer ring ejection seat 21, and the air inlet end of the inner ring air inlet passage 17 is opposite to the air outlet end of the inner ring ejection seat 22, that is, a first gap is formed between the air inlet end of the outer ring air inlet passage 16 and the outer ring ejection seat 21, and a second gap is formed between the air inlet end of the inner ring air inlet passage 17 and the air outlet end of the inner ring ejection seat 22, and the first gap and the second gap can be communicated with the air supplementing gap formed between the lower surface of the fire distributor 1 and the upper surface of the burner 2.

[0044] During normal cooking, gas is supplied into the outer ring air inlet passage 16 through the outer ring ejection seat 21, so that the gas is combusted in the outer ring fire groove 11 communicated with the outer ring air inlet passage 16 to form an outer ring fire, and at the same time, gas can be supplied into the inner ring air inlet passage 17 through the inner ring ejection seat 22, so that the gas is combusted in the inner ring fire groove 13 communicated with the inner ring air inlet passage 17 to form an inner ring fire, and the inner ring fire is combusted inside the outer ring fire. During the process, air is supplemented into the first gap and the second gap through the air supplementing gap formed between the lower surface of the fire distributor 1 and the upper surface of the burner 2, and air is also supplemented into the central passage 14 penetrating the bottom surface of the fire distributor 1 through the air supplementing gap, so that the gas entering the outer ring air inlet passage 16, the inner ring air inlet passage 17 and the central passage 14 is a mixed gas of air and gas.

[0045] When the gas is ejected at high speed from the gas outlet end of the outer ring ejector seat 21 and the inner ring ejector seat 22, a low pressure area is formed near the corresponding gas outlet end according to Bernoulli's principle, and the surrounding air is sucked into the mixing channel between the gas inlet end and the gas outlet end, i.e. the first gap and the second gap, under the action of the pressure difference, and then enters the corresponding outer ring gas inlet channel 16 and inner ring gas inlet channel 17 to realize preliminary mixing. The provision of the mixing channel provides an initial mixing space for the gas and air, and the air and gas begin to contact and mix in this channel space. Due to the high-speed flow of the gas and the entrainment of the air, a certain degree of turbulence is formed, which enables the gas and air to penetrate and mix more fully, creating good conditions for subsequent full combustion in the combustion chamber; at the same time, the mixing channel provides a margin for thermal expansion of the components to avoid excessive stress between the components due to thermal expansion, thereby preventing component deformation, damage or affecting the normal supply of gas.

[0046] On the basis of the above embodiment, the gas inlet end of the outer ring gas inlet channel 16 and the inner ring gas inlet channel 17 is in the form of an expanded structure to increase the opening area of the respective gas inlet end, so that more air can enter the pipeline under the entraining action of the gas jet to provide sufficient oxygen for the gas to burn fully, so as to achieve better combustion effect; and the air enters the pipeline more smoothly, reducing air resistance and turbulence. According to Bernoulli's principle, the low pressure area formed by the high-speed flow of the gas at the expanded portion is more stable, and can more efficiently entrain air; at the same time, after the air enters the corresponding pipeline, the expanded structure allows the air and gas to have a larger contact area and more sufficient contact time, which facilitates more uniform mixing of the two, allowing the combustion to be more complete and stable, improving combustion efficiency and reducing pollutant generation, which helps to maintain a relatively stable gas and air mixing ratio, making the combustion process closer to the ideal state, improving the performance and stability of the burner, and reducing problems such as incomplete combustion and unstable flame caused by fluctuations in the mixing ratio; and during installation, the expanded structure provides a larger alignment tolerance range during installation, which can compensate for the dimensional errors and positional deviations caused during manufacturing and installation to some extent. Even if there is a small deviation between the components, the expanded structure reduces the installation precision requirement, improves the installation efficiency and accuracy, and also ensures normal gas flow and entraining effect.

[0047] Furthermore, the inner diameter of the gas outlet end of the outer ring gas inlet channel 16 and the inner ring gas inlet channel 17 gradually increases to reduce the resistance of the gas when it is discharged, reduce the exhaust back pressure, and make the gas discharge speed relatively stable and moderate, reducing the risk of backfire. The larger diameter of the gas outlet end enables the discharged gas flow to be more stable, reducing fluctuations and turbulence in the gas flow, which is beneficial to the stability of the subsequent combustion process, making the flame more stable and the combustion more uniform, reducing problems such as incomplete combustion and flickering flame caused by unstable gas flow.

[0048] The burner of the utility model, please refer toFigures 1 to 7 Further comprising an outer ring air supplement channel 18, the outer ring air supplement ejection seat 25 is arranged on the outer ring ejection seat 21, the outer ring ejection seat 21 and the outer ring air supplement ejection seat 25 have a bypass channel 26, the gas pipe of the stove is communicated with the gas inlet end of the outer ring ejection seat 21, the outer ring ejection seat 21 is communicated with the gas inlet end of the bypass channel 26, the gas outlet end of the bypass channel 26 is communicated with the gas inlet end of the outer ring air supplement ejection seat 25, and the gas outlet end of the outer ring air supplement ejection seat 25 is opposite to the gas inlet end of the outer ring air supplement channel 18.

[0049] In the embodiment, the gas outlet end of the outer ring air supplement ejection seat 25 is opposite to the gas inlet end of the outer ring air supplement channel 18, so that the third gap is formed between the gas outlet end of the outer ring air supplement ejection seat 25 and the gas inlet end of the outer ring air supplement channel 18, and the third gap is communicated with the air supplement gap.

[0050] In the cooking process, the gas is introduced into the outer ring ejection seat 21 through the gas pipe, part of the gas can enter the bypass channel 26 and be sprayed out through the outer ring air supplement ejection seat 25, the gas sprayed out of the gas outlet end of the outer ring air supplement ejection seat 25 enters the outer ring air supplement channel 18, and then the gas and air are supplemented through the outer ring air supplement channel 18 towards the outer ring fire groove 11, so that the flame formed in the outer ring fire groove 11 burns more fully. Specifically, when the gas is sprayed out of the gas outlet end of the outer ring air supplement ejection seat 25 at high speed, according to Bernoulli's principle, a low pressure area is formed near the corresponding gas outlet end, and the surrounding air is sucked into the third gap between the gas outlet end of the outer ring air supplement ejection seat 25 and the outer ring air supplement channel 18 under the action of the pressure difference, and then enters the corresponding outer ring air supplement channel 18 together with the gas, realizing preliminary mixing. The third gap provides an initial mixing place for the gas and air, and the air and 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 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, avoiding excessive stress between the components due to thermal expansion, thereby preventing deformation, damage or affecting the normal supply of gas.

[0051] The burner of the utility model, please refer to Figure 3 And Figure 4 The outer ring air inlet channel 16 and the outer ring air supplement channel 18 are symmetrically arranged on the two sides of the inner ring fire groove 13, and the directions of the gas outlet ends of the outer ring air inlet channel 16 and the outer ring air supplement channel 18 are opposite.

[0052] During the cooking process, the outer ring air supplement channel 18 and the outer ring air inlet channel 16 simultaneously supplement gas to the outer ring fire groove 11, forming a double air passage structure, so that the gas introduced from the outer ring injection seat 21 is divided into two parts and enters the outer ring fire groove 11, so that the outer ring fire groove 11 is burned and forms a uniform flame, and at the same time, the dispersion of the gas improves the full combustion effect of the gas.

[0053] The gas outlet ends of the outer ring air inlet channel 16 and the outer ring air supplement channel 18 are opposite in direction, so that the openings of the outer ring air inlet channel 16 and the outer ring air supplement channel 18, which communicate with the outer ring fire groove 11, are symmetrically distributed with the center of the fire divider 1 as the center, and the air supplement directions of the two are opposite, so as to ensure the uniformity of the gas entering the outer ring fire groove 11.

[0054] And the structure of the outer ring air supplement channel 18 and the outer ring air inlet channel 16 is the same, that is, the air inlet end of the outer ring air supplement channel 18 is in an expanded structure, so as to increase the opening area of the air inlet end, so that more air can enter the pipeline under the injection action of the gas jet, providing sufficient oxygen for the full combustion of the gas, so as to achieve better combustion effect. And the inner diameter of the gas outlet end of the outer ring air supplement channel 18 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, and the larger gas outlet end diameter 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, and the combustion more uniform, reduces the problems of incomplete combustion, flame flickering and the like caused by unstable gas flow.

[0055] The burner of the utility model, please refer to Figures 2 to 4 The bottom surface of the fire divider 1 includes an outer ring bottom surface a as the bottom of the outer ring fire groove 11 and an inner ring bottom surface b as the bottom of the inner ring fire groove 13, and the outer ring bottom surface a and the inner ring bottom surface b are connected through at least one of the outer ring air inlet channel 16, the outer ring air supplement channel 18 and the inner ring air inlet channel 17.

[0056] In this embodiment, the outer ring bottom surface a is in a circular ring plate structure, the inner ring bottom surface b is in a circular plate structure, and the inner diameter of the outer ring bottom surface a is greater than the diameter of the inner ring bottom surface b, so that the air supplement space of the communication air supplement groove 12 is formed between the outer ring bottom surface a and the inner ring bottom surface b. During the cooking process, air can enter the air supplement groove 12 from the air supplement space to supplement air for gas combustion.

[0057] At least one of the outer ring air inlet channel 16, the outer ring air supplement channel 18 and the inner ring air inlet channel 17 is connected with the outer ring bottom surface a and the inner ring bottom surface b at the same time, so that the outer ring fire trench 11 and the inner ring fire trench 13 are connected to form a whole under the connection of the outer ring air inlet channel 16, the outer ring air supplement channel 18 and the inner ring air inlet channel 17, and the structural stability of the distributor 1 is ensured. As one of the parallel schemes, any one of the outer ring air inlet channel 16 and the inner ring air inlet channel 17 is connected with the outer ring bottom surface a and the inner ring bottom surface b at the same time; as the second parallel scheme, any two of the outer ring air inlet channel 16, the outer ring air supplement channel 18 and the inner ring air inlet channel 17 are connected with the outer ring bottom surface a and the inner ring bottom surface b at the same time; as the third parallel scheme, all of the outer ring air inlet channel 16, the outer ring air supplement channel 18 and the inner ring air inlet channel 17 are connected with the outer ring bottom surface a and the inner ring bottom surface b at the same time.

[0058] The burner of the utility model, please refer to Figures 1 to 7 The outer ring bottom surface a is equipped with the first support surface a2 with the outer ring air inlet channel 16 and the inner ring air inlet channel 17, and the outer ring bottom surface a is equipped with the second support surface a3 with the outer ring air supplement injection seat 25, and the outer ring injection seat 21 and the inner ring injection seat 22 support the distributor 1 through the first support surface a2, and the outer ring air supplement injection seat 25 supports the distributor 1 through the second support surface a3.

[0059] When installing, the distributor 1 is installed on the furnace end 2, and the outer ring injection seat 21 and the inner ring injection seat 22 support the distributor 1 through the first support surface a2 at the same time, and the outer ring air supplement injection seat 25 supports the distributor 1 through the second support surface a3 at the same time, and since the directions of the air outlet ends of the outer ring air inlet channel 16 and the outer ring air supplement channel 18 are opposite, the positions of the first support surface a2 and the second support surface a3 are symmetrically distributed to ensure stable installation of the distributor 1.

[0060] The burner of the utility model, please refer to Figure 3 The air outlet ends of the outer ring air inlet channel 16 and the outer ring air supplement channel 18 extend to the outer ring bottom surface a and form the air sink groove a1 on the outer ring bottom surface a.

[0061] In the embodiment, the two air sink grooves a1 are respectively opposite to the air outlet ends of the outer ring air inlet channel 16 and the outer ring air supplement channel 18.

[0062] During the cooking process, the mixed gas of air and gas is indirectly introduced into the outer ring fire groove 11 from the outer ring air inlet channel 16 and the outer ring air supplement channel 18. The directly opposite air sink groove a1 can guide the airflow to flow downward, so that the airflow forms a certain disturbance and backflow at the air sink groove a1, thereby promoting the more sufficient mixing of the gas and air, creating conditions for more complete combustion, improving the combustion efficiency, releasing more heat from the combustion, and forming a relatively stable area inside and around the air sink groove a1. When the mixed gas flow rushes to the air sink groove a1, a low-speed backflow area is formed, which can retain part of the high-temperature combustion products, continuously provide an ignition source for the subsequent combustible mixed gas, ensure that the flame can remain stable under various working conditions, and prevent the phenomenon of flickering, jumping or even extinguishing of the flame. In addition, during the combustion process, the gas may carry some impurities, and the high-temperature gas produced by combustion may form condensate during the cooling process. The air sink groove a1 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.

[0063] The burner of the utility model, please refer to Figure 1 and Figure 2 It also 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 13 and the central channel 14 at the same time. The side surface of the inner ring fire cover 4 is provided with an inner ring fire hole 41. The top surface of the inner ring fire cover 4 is provided with a central fire hole 42 on the part opposite to the central channel 14.

[0064] During the cooking process, the outer ring, the inner ring and the center three different flame areas are formed by the cooperation of the outer ring fire cover 3, the inner ring fire cover 4, the outer ring fire groove 11, the inner ring fire groove 13 and the central channel 14 at different positions. The size and intensity of the flame in different areas can be controlled according to actual needs, realizing the fine adjustment of the combustion. For example, during cooking, slow stewing can only use the outer ring fire groove 11 and / or the inner ring fire groove 13 to output small flames 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 13 and the central channel 14 can be opened at the same time, and larger and more intense flames can be output through the outer ring fire hole 31, the inner ring fire hole 41 and the central fire hole 42. The outer ring fire groove 11, the inner ring fire groove 13 and the central channel 14 and the corresponding fire cover and fire hole cooperate with each other, so that the heat can be more uniformly distributed in the area above the burner.
