Description

Technical Field

[0001] The utility model relates to the technical field of cooking stoves, in particular to an energy-gathering ring of a burner and a burner. Background Art

[0002] Gas stoves, liquefied gas stoves, gas stoves, etc. are collectively referred to as burners. The burner head is the core component of the burner, and its performance and quality directly affect the use effect and safety of the burner. Generally, the performance of the burner is mainly judged from the following indicators, such as thermal efficiency, heat load, combustion stability, and combustion sufficiency, etc.

[0003] Among them, the thermal efficiency is one of the important indicators. The thermal efficiency is an important indicator to measure the energy utilization rate of the gas stove, and the thermal efficiency indicates how much of the heat generated by the combustion of the gas is effectively utilized. A burner head with high thermal efficiency means less energy waste and higher cooking efficiency.

[0004] In the prior art, in order to improve the thermal efficiency of the burner, an energy-gathering ring is generally used. For example, in the existing patent CN218954961U, in the energy-gathering ring pot stand and the gas stove, the means to improve the thermal efficiency of the burner is to add several circles of flow disturbing components on the energy-gathering ring. The principle of the flow disturbing components in the existing patent solution to improve the burner is as follows: after the cookware is placed on the fixing member, a predetermined gap is formed between the flow disturbing components and the bottom of the pot. Under this predetermined gap, the high-temperature flue gas generated after the cooking stove burns can flow through the flow disturbing components. When the high-temperature flue gas passes through the flow disturbing components, the air flow will be separated by the flow disturbing components, and a laminar vortex street or a turbulent vortex street will be formed behind the flow disturbing components. The boundary layer of the high-temperature flue gas flow is broken, resulting in strong disturbance and mixing, thereby increasing the convective heat transfer coefficient and enhancing the convective heat transfer ability. That is, in the existing patent CN218954961U, the improvement of the thermal efficiency is to change and disturb the boundary layer of the high-temperature flue gas flow, increase the convective heat transfer coefficient, enhance the flow heat transfer ability, increase the effective heat absorbed by the cookware, and improve the thermal efficiency.

[0005] As is well known, when the burner is working, the burner itself will be heated and generate heat, and the heat on the burner radiates outward, resulting in a part of heat loss, reducing the thermal efficiency of the burner. And based on the above existing patent CN218954961U, no matter how the high-temperature flue gas on the energy-gathering ring is mixed, this part of heat efficiency radiation cannot be prevented or reduced, affecting the thermal efficiency of the burner. Summary of the Utility Model

[0006] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an energy-gathering ring of a burner. During the continuous combustion process of the burner head, the heated air below the first energy-gathering ring enters the position of the burner head, and the heat in the heated air is utilized.

[0007] In order to overcome at least one defect of the above-mentioned prior art, the utility model also provides a burner, which has the aforementioned burner energy focusing ring, so that the burner can recover and utilize the heat radiated outward, thereby improving the thermal efficiency of the burner.

[0008] The technical solution adopted by the utility model to solve the problem is:

[0009] A burner energy focusing ring includes a first energy focusing ring installed on a stove top panel, wherein the first energy focusing ring surrounds the outside of a stove head.

[0010] Furthermore, the first energy focusing ring surrounds the outside of the stove head and forms a first annular channel between the stove head. The heated air below the first energy focusing ring rises from the first annular channel and enters the stove head position. The heated air enters the stove head position and mixes with the combustion gas at the stove head position to promote combustion, while utilizing the heat in the heated air.

[0011] Further, the first energy focusing ring comprises a wrapping portion, an extending portion and a guiding portion which are connected in sequence;

[0012] The wrapping portion is annular and columnar and is placed above the stove panel and perpendicular to the stove panel. The wrapping portion is separated from the stove panel at an end close to the stove panel to form an air intake passage.

[0014] The distance between the extension portion and the stove top panel gradually decreases from the end connected to the wrapping portion to the end connected to the guide portion.

[0015] Furthermore, a second energy focusing ring is arranged below the first energy focusing ring, and a first interlayer is formed between the first energy focusing ring and the second energy focusing ring. After the stove is ignited, the first energy focusing ring is heated, and the heat on the first energy focusing ring radiates downward, and the air in the first interlayer is heated and its temperature rises. When the stove continues to burn, the heated air in the first interlayer enters the stove position to utilize the heat in the heated air.

[0016] Furthermore, the second energy focusing ring surrounds the outside of the stove head and forms a second annular channel between the stove head. The second annular channel is located below the first annular channel and is connected to the first annular channel. The heated air in the first interlayer rises from the second annular channel and enters the first annular channel, and finally enters the stove head position and mixes with the combustion gas at the stove head position to promote combustion, while utilizing the heat in the heated air.

[0017] Furthermore, a plurality of support pads are detachably provided on the second energy focusing ring, and the support pads support the first energy focusing ring;

[0018] The second energy focusing ring comprises a first connecting portion, a second connecting portion and a third connecting portion which are connected in sequence;

[0019] The first connecting portion is columnar, disposed inside the wrapping portion, and perpendicular to the stove top panel, and the first connecting portion and the wrapping portion support and form the air intake channel;

[0020] One end of the second connection portion is connected to the top of the first connection portion, and the other end of the second connection portion is connected to the third connection portion, the third connection portion is located below the guide portion and parallel to the stove top panel; the second annular channel is formed between the end of the third connection portion away from the second connection portion and the stove head;

[0021] The distance between the second connection portion and the stove top panel gradually decreases from the end close to the first connection portion to the end close to the third connection portion, and the inclination angle of the second connection portion is smaller than the inclination angle of the extension portion; the minimum distance between the second connection portion and the extension portion is larger than the distance between the third connection portion and the guide portion; the minimum distance between the second connection portion and the extension portion is larger than the distance between the first connection portion and the wrapping portion; the bottom end position of the wrapping portion is not higher than the bottom end position of the first connection portion;

[0022] The supporting pad is disposed on both the first connecting portion and the third connecting portion.

[0023] Furthermore, a third energy focusing ring is arranged below the second energy focusing ring, and a second interlayer is formed between the third energy focusing ring and the second energy focusing ring. After the stove is ignited, the second energy focusing ring is heated, and the heat on the second energy focusing ring radiates downward, and the air in the second interlayer is heated and its temperature rises. When the stove continues to burn, the heated air in the second interlayer enters the stove position to utilize the heat in the heated air.

[0024] A burner comprises a stove head and the aforementioned burner energy focusing ring, wherein the burner energy focusing ring is arranged outside the stove head;

[0025] The stove head includes a first fire cover and a second fire cover which are coaxially arranged. The first fire cover is placed on the inner side of the second fire cover. The second fire cover is provided with an overflow hole. The overflow hole is arranged on the outer side of the second fire cover and faces the first energy focusing ring.

[0028] 1. After the stove is ignited, the first energy-gathering ring is heated, and the air below the first energy-gathering ring is heated and heated. When the stove continues to burn, the heated air below the first energy-gathering ring enters the stove position, and the heat in the heated air is utilized. The so-called utilization of the heat in the air means that the heated air contacts and mixes with the combustion gas, which promotes the combustion of the combustion gas. Because the air has been heated, the heated air mixes with the combustion gas at this time to generate heat. This heat includes the heat in the original heated air, that is, the heat in the heated air is utilized.

[0029] 2. The setting of the energy focusing ring realizes the reception, collection and transfer of heat around the stove head, so that the heat originally radiated directly into the air will heat up the energy focusing ring after contacting the energy focusing ring. After the temperature of the energy focusing ring rises, the heat radiates downward to heat the air below the energy focusing ring, and then the air is utilized. In other words, the heat radiated from the burner stove head is collected to facilitate the reuse of the heat.

[0030] 3. A second energy focusing ring is arranged below the first energy focusing ring, or a third energy focusing ring is arranged below the second energy focusing ring, so as to increase the number of energy focusing ring layers and utilize the heat radiated from the stove head multiple times.

[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See also Figures 1 to 3 , discloses an embodiment structure of a burner. A burner includes a stove head 4 and a burner energy focusing ring, and the burner energy focusing ring is placed outside the stove head 4. The burner energy focusing ring receives, recovers and converts the heat radiated outward by the combustion of the combustion gas on the stove head, and finally can utilize the radiated heat, which greatly improves the thermal efficiency of the burner. In order to facilitate technical personnel in this field to understand the function and structure of the burner energy focusing ring, the burner energy focusing ring is specifically introduced below.

[0042] like Figure 3As shown, a burner energy focusing ring includes a first energy focusing ring 1 installed on a stove top panel 3, and the first energy focusing ring 1 surrounds the outside of a stove head 4. After the stove head 4 is ignited, the first energy focusing ring 1 is heated, and the air below the first energy focusing ring 1 is heated and heated. When the stove head 4 continues to burn, the heated air below the first energy focusing ring 1 enters the position of the stove head 4, and the heat in the heated air is utilized.

[0043] Based on the above technical solution, after the stove is ignited, the combustion gas on the stove burns and generates heat. Part of the heat is absorbed by the pot placed on the stove, and the other part will radiate outward into the surrounding air. The heat radiated outward will contact the first energy focusing ring, and the first energy focusing ring absorbs the heat and heats up. The heated energy focusing ring will also radiate heat outward, and this heat will heat the air above and below the first energy focusing ring. The hot air above the first energy focusing ring contacts the bottom surface of the pot and is absorbed by the pot, while the heated air below the first energy focusing ring will enter the stove position. Specifically, when the combustion gas on the stove 4 continues to burn, the combustion gas consumes the air around the stove, and the air becomes thinner near the periphery of the stove, and the air pressure decreases. At this time, the heated air below the first energy focusing ring will move to a position with lower air pressure, that is, the heated air below the first energy focusing ring moves toward the stove, that is, the heat in the heated air is utilized.

[0044] The heated air located under the first energy focusing ring moves toward the stove head. During this process, external cold air will continue to enter under the first energy focusing ring, and the heat on the first energy focusing ring will continue to radiate downward, continuously heating the cold air under the first energy focusing ring, so that the air entering the stove head position is all hot air, thereby realizing the continuous collection and reuse of heat on the first energy focusing ring.

[0045] The so-called utilization of heat in the air here refers to the promotion of combustion of the combustion gas after the heated air contacts and mixes with the combustion gas. Because the air has been heated, the heated air and the combustion gas are mixed to generate heat. This heat includes the heat in the original heated air, that is, the heat in the heated air is utilized.

[0046] Based on the above technical solution, the concept of the energy-gathering ring in the utility model is to recover the heat radiated outward from the stove. The heat radiated outward from the stove heats up the first energy-gathering ring, and the air below the first energy-gathering ring is heated up. In order to avoid heat loss outward, the hot air below the first energy-gathering ring is utilized to avoid the hot air below the first energy-gathering ring from moving outward and causing heat loss.

[0047] like Figure 3As shown, the first energy focusing ring 1 surrounds the outside of the stove head 4 and forms a first annular channel 14 between the stove head 4. The heated air below the first energy focusing ring 1 rises from the first annular channel 14 and enters the stove head 4 position. The heated air enters the stove head 4 position and mixes with the combustion gas at the stove head 4 position to promote combustion, while utilizing the heat in the heated air.

[0048] The first annular channel is arranged close to the stove head, so that the air below the first energy focusing ring can quickly enter the stove head position after being discharged from the first annular channel, and mix with the combustion gas on the stove head to participate in combustion.

[0049] like Figure 3 As shown, the first energy focusing ring 1 includes a wrapping portion 11, an extending portion 12 and a guiding portion 13 which are connected in sequence.

[0050] The wrapping portion 11 is annular and columnar and is placed above the stove top panel 3 and perpendicular to the stove top panel 3 . The wrapping portion 11 is separated from the stove top panel 3 at its end close to the stove top panel 3 to form an air intake passage.

[0051] The extension portion 12 is annular, one end of the extension portion 12 is connected to the end of the wrapping portion 11 away from the stove top panel 3, and the other end of the extension portion 12 extends toward the stove head 4 and is connected to the guide portion 13. The guide portion 13 is annular, and the first annular channel 14 is formed between the end of the guide portion 13 away from the extension portion 12 and the stove head 4. The guide portion 13 is parallel to the stove top panel 3.

[0052] The distance between the extension portion 12 and the stove top panel 3 gradually decreases from the end connected to the wrapping portion 11 to the end connected to the guide portion 13 .

[0053] The structure of the extension portion on the first energy-gathering ring 1 is in a state of being high outside and low inside, which is conducive to the heat radiated outward from the stove head to fully contact with the upper surface of the first energy-gathering ring 1, and maximizes the absorption of the heat radiated outward from the stove head by the first energy-gathering ring. In addition, the structure of the first energy-gathering ring 1 is in a state of being high outside and low inside, so that the first energy-gathering ring also has a certain windproof ability, preventing the flow of external air from affecting the normal combustion of the combustion gas on the stove head, or affecting the position and direction of the flame on the burner, ensuring that the flame on the burner is located at the bottom of the pot, increasing the amount of heat absorbed by the pot, and improving the thermal efficiency of the stove head.

[0054] The structure of the extended part on the first energy focusing ring 1 is high on the outside and low on the inside, so that the distance between the first energy focusing ring and the stove panel gradually decreases from the outside to the inside, making it easier for the air under the first energy focusing ring to enter the stove head position during the continuous combustion of the combustion gas on the stove head.

[0055] The setting of the wrapping part on the first energy focusing ring 1 realizes the encirclement of the space below the first energy focusing ring, preventing the air below the first energy focusing ring from flowing outward quickly, and ensuring that the air below the first energy focusing ring can flow toward the stove head under the impetus of external fresh air, thereby realizing the recovery and utilization of the heat radiated from the stove head.

[0056] The setting of the guide part on the first energy focusing ring 1 facilitates the formation of the first annular channel. At the same time, the guide part is parallel to the stove panel, and the gas entering the first annular channel is evenly distributed to prevent the flame generated by the combustion on the stove from shaking. In addition, the guide part is parallel to the stove panel, and can receive and block water droplets or oil droplets dripping onto the first energy focusing ring to prevent water droplets or oil droplets from entering the stove.

[0057] like Figure 3 As shown, a second energy focusing ring 2 is further provided below the first energy focusing ring 1, and a first interlayer is formed between the first energy focusing ring 1 and the second energy focusing ring 2. After the stove 4 is ignited, the first energy focusing ring 1 is heated, and the heat on the first energy focusing ring 1 is radiated downward, and the air in the first interlayer is heated and heated up. When the stove 4 continues to burn, the heated air in the first interlayer enters the stove 4, and the heat in the heated air is utilized.

[0058] Based on the above scheme, when the stove 4 continues to burn, the heated air in the first interlayer enters the position of the stove 4, and the heat in the heated air is utilized. After the stove is ignited, the combustion gas on the stove burns and generates heat. Part of the heat is absorbed by the pot placed on the stove, and the other part will radiate outward to the surrounding air. The heat radiated outward will contact the first energy focusing ring, and the first energy focusing ring absorbs the heat and heats up. The first energy focusing ring heats the air in the first interlayer, and the air in the first interlayer heats up. The heated air continues to burn with the combustion gas on the stove, and the heated air in the first interlayer moves to the position of the stove and participates in the combustion. As the heated air in the first interlayer continues to enter the position of the stove, the air outside the first energy focusing ring continues to enter the first interlayer, is heated by the first energy focusing ring, and absorbs the heat on the first energy focusing ring, so that the air that continues to enter the stove is hot air, which prevents the heat generated by the stove from radiating outward.

[0059] The so-called utilization of heat in the air here refers to the promotion of combustion of the combustion gas after the heated air contacts and mixes with the combustion gas. Because the air has been heated, the heated air and the combustion gas are mixed to generate heat. This heat includes the heat in the original heated air, that is, the heat in the heated air is utilized.

[0060] Based on the above scheme, when the stove 4 continues to burn, the heated air in the first interlayer enters the stove 4 to utilize the heat in the heated air. Here, the heated air in the first interlayer enters the stove to utilize the heat in the heated air, which is the same as the principle and process of the heated air under the first energy focusing ring entering the stove position and utilizing the heat in the hot air under the first energy focusing ring, and will not be described in detail here.

[0061] Based on the above solution, a second energy-gathering ring is arranged below the first energy-gathering ring to form a first interlayer. The thickness of the first interlayer is less than the distance between the first energy-gathering ring and the stove panel, which facilitates the rapid heating of the air in the first interlayer, that is, the temperature of the air entering the stove position is increased, which is beneficial to improving the combustion efficiency. In addition, the second energy-gathering ring is arranged to further restrict the air below the first energy-gathering ring, prevent the air below the first energy-gathering ring from flowing outward quickly, and improve the utilization rate of the heat radiated outward by the stove.

[0062] like Figure 3 As shown, the second energy focusing ring 2 surrounds the outside of the stove head 4 and forms a second annular channel 24 between the stove head 4. The second annular channel 24 is located below the first annular channel 14 and is connected to the first annular channel 14. The heated air in the first interlayer rises from the second annular channel 24 and enters the first annular channel 14, and finally enters the position of the stove head 4 and mixes with the combustion gas at the position of the stove head 4 to promote combustion, while utilizing the heat in the heated air.

[0063] The second annular channel is located below the first annular channel, which is conducive to the stable rise of hot air in the first interlayer, entering the stove position, participating in combustion, and ensuring stable combustion.

[0064] like Figure 3 As shown, the second energy focusing ring 2 is detachably provided with a plurality of support pads 25, which support the first energy focusing ring 1, realize the installation and fixation of the first energy focusing ring, and make the first energy focusing ring stable and reliable, thereby ensuring the stability of the pot placed on the first energy focusing ring. At the same time, the support pads 25 maintain the relative position between the first energy focusing ring and the second energy focusing ring, thereby ensuring the thickness and position of the first interlayer.

[0065] like Figure 3 As shown, the second energy focusing ring 2 includes a first connecting portion 21, a second connecting portion 22 and a third connecting portion 23 which are connected in sequence.

[0066] The first connection portion 21 is columnar, disposed inside the wrapping portion 11 and perpendicular to the stove top panel 3 , and the first connection portion 21 and the wrapping portion 11 support and form the air intake passage.

[0067] One end of the second connection portion 22 is connected to the top of the first connection portion 21, and the other end of the second connection portion 22 is connected to the third connection portion 23. The third connection portion 23 is located below the guide portion 13 and parallel to the stove top panel 3. The second annular channel 24 is formed between the end of the third connection portion 23 away from the second connection portion 22 and the stove head 4.

[0068] The distance between the second connection portion 22 and the stove top panel 3 gradually decreases from the end close to the first connection portion 21 to the end close to the third connection portion 23, and the inclination angle of the second connection portion 22 is smaller than the inclination angle of the extension portion 12. The minimum distance between the second connection portion 22 and the extension portion 12 is greater than the distance between the third connection portion 23 and the guide portion 13. The minimum distance between the second connection portion 22 and the extension portion 12 is greater than the distance between the first connection portion 21 and the wrapping portion 11. The bottom end position of the wrapping portion 11 is not higher than the bottom end position of the first connection portion 21.

[0069] The second energy focusing ring structure formed by the first connecting part 21, the second connecting part 22 and the third connecting part 23 makes the first interlayer formed between the second energy focusing ring and the first energy focusing ring have a structure that is thin at both ends and thick in the middle along the air flow direction. This structure allows external air to quickly enter the first interlayer, and be heated in the first interlayer, and then smoothly enter the stove position. The heated air flow entering the stove position is large, and can be fully mixed with the combustion gas at the stove position to participate in combustion, thereby ensuring full combustion of the combustion gas, improving the thermal efficiency of the stove, and improving the safety performance of the burner.

[0070] The second energy-gathering ring structure formed by the first connecting part 21, the second connecting part 22 and the third connecting part 23 makes the first interlayer formed between the second energy-gathering ring and the first energy-gathering ring present a structure with thin ends and thick middle along the air flow direction. Fresh air enters between the extension part and the second connecting part from the air intake channel with a large airflow. After entering here, the airflow is reduced, so that the airflow can fully contact with the first energy-gathering ring, absorb the heat on the first energy-gathering ring, and improve the heat utilization rate on the first energy-gathering ring. The fresh air flow enters between the extension part and the second connecting part from the air intake channel, impacts the air between the extension part and the second connecting part, so that the air is quickly mixed and moved between the extension part and the second connecting part, ensuring that the air is heated evenly.

[0071] The second connecting portion on the second energy focusing ring is arranged in an inclined shape, and the inclination angle is smaller than the inclination angle of the extension portion. On the one hand, it ensures the thickness of the space between the extension portion and the second connecting portion, and on the other hand, it improves the strength of the second energy focusing ring, while at the same time guiding and stabilizing the flow direction of the air between the extension portion and the second connecting portion.

[0072] like Figure 3As shown, the support pad 25 is disposed on both the first connection portion 21 and the third connection portion 23 to better maintain the space between the first energy focusing ring and the second energy focusing ring, while further ensuring the stability of the first energy focusing ring.

[0073] In the technical solution of the utility model, the number of energy focusing rings can be set as needed. In the above solution, there is a structure with one layer of energy focusing rings, that is, only the first energy focusing ring is set, and there is also a structure with two layers of energy focusing rings, that is, a second energy focusing ring is set below the first energy focusing ring. Of course, the energy focusing rings can also be three, four or more layers.

[0074] For example, a third energy focusing ring is further arranged below the second energy focusing ring 2, and a second interlayer is formed between the third energy focusing ring and the second energy focusing ring 2. After the stove 4 is ignited, the second energy focusing ring 2 is heated, and the heat on the second energy focusing ring 2 radiates downward, and the air in the second interlayer is heated and its temperature rises. When the stove 4 continues to burn, the heated air in the second interlayer enters the position of the stove 4, and the heat in the heated air is utilized.

[0075] During the continuous combustion of the combustion gas on the stove, heat is continuously radiated outwards. Generally, the first energy focusing ring is heated first, and the temperature is the highest after heating. The air below the first energy focusing ring is heated, and at the same time, the heat radiated outwards by the stove will also heat the second energy focusing ring below the first energy focusing ring. The second energy focusing ring absorbs the heat radiated by the stove, and the second energy focusing ring will also heat the air above and below it when heated. Similarly, the third energy focusing ring will also directly absorb the heat radiated by the stove, and the third energy focusing ring can heat and increase the temperature of the air above and below it. The heated air between the first interlayer and the second interlayer flows toward the stove position to participate in the combustion, thereby further realizing the utilization of the heat radiated outwards from the stove and avoiding a large amount of heat radiating outwards and being lost.

[0076] In this solution, a third energy focusing ring is added. After the stove 4 is ignited, the second energy focusing ring 2 is heated, and the heat on the second energy focusing ring 2 is radiated upward and downward, heating the air above and below the second energy focusing ring respectively. At the same time, the third energy focusing ring also absorbs the heat radiated by the stove, and heats the air above and below the third energy focusing ring. The air in the second interlayer is heated and its temperature rises. When the stove 4 continues to burn, the heated air in the second interlayer enters the position of the stove 4, and the heat in the heated air is utilized.

[0077] In this solution, by increasing the number of energy-gathering rings, the number of times the heat radiated by the stove is absorbed is increased, thereby improving the thermal efficiency of the stove. Of course, in actual use, the number of energy-gathering rings is not infinitely increased, nor is the thermal efficiency of the stove higher with more energy-gathering rings. When selecting the number of energy-gathering rings, the height of the stove needs to be considered, as well as the air velocity and flow rate of the hot air below the energy-gathering rings entering the stove. Generally, in use, two or three layers of energy-gathering rings are the best.

[0078] like Figures 1 to 3 As shown, a burner is disclosed, which includes a stove head 4 and the aforementioned burner energy focusing ring, and the burner energy focusing ring is placed outside the stove head 4.

[0079] The stove head 4 comprises a first fire cover 41 and a second fire cover 42 which are coaxially arranged, wherein the first fire cover 41 is placed inside the second fire cover 42, and the second fire cover 42 is provided with an overflow hole, which is arranged on the outer surface of the second fire cover 42 and faces the first energy focusing ring 1, and the inner edge position of the first energy focusing ring 1 is lower than the position of the overflow hole on the second fire cover 42. It is ensured that the heat radiated outward from the stove head absorbed by the combustion energy focusing ring can be quickly recovered and utilized.
