[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0031] The terms "a", "an", and "the" are used to indicate that there are one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.

[0032] A honeycomb body according to an embodiment of the present invention comprises an inner ring region, an outer ring region and a transition region, wherein the transition region is located between the inner ring region and the outer ring region, the inner ring region is provided with a first air outlet, the transition region is provided with a second air outlet, and the outer ring region is provided with a third air outlet, wherein an air outlet area of ​​the second air outlet is greater than or equal to an air outlet area of ​​the first air outlet, and an air outlet area of ​​the third air outlet located on the periphery of the outer ring region is smaller than an air outlet area of ​​the transition region.

[0033] In the burner, a flame distribution plate is installed on the top of the burner, and a honeycomb body is installed on the top of the flame distribution plate. When the burner has two air supply channels, the inner ring area corresponds to the air supply channel on the inner side of the burner, and the outer ring area and the transition area are located on the air supply channel on the outer side of the burner; when the burner has three air supply channels, the inner ring area, the transition area and the outer ring area can respectively correspond to the three air supply channels on the burner from the inside to the outside. In order to correspond, a partition can be installed between the honeycomb body and the flame distribution plate. The partition divides the flame distribution plate into multiple sub-cavities to correspond to the air supply channels on the burner. The partition part can be an annular partition, a cylinder, etc.

[0034] In this application, the transition region is designed to enhance flame transfer. This can be achieved by ensuring that the outlet area of ​​the second outlet is equal to or greater than that of the first outlet. By making the outlet area of ​​the third outlet located on the periphery of the outer ring region smaller than that of the transition region, the outlet area of ​​the first outlet can be made larger than that of the third outlet located on the periphery of the outer ring region. This design has the advantage of increasing the gas concentration at the inner ring or ignition needle, which helps improve ignition success rates and speeds up ignition. During ignition, the cookware is already placed on the pot stand, forming a semi-enclosed space between the burner and the pot bottom. If the gas concentration in the inner ring is insufficient during ignition, and the outlet area of ​​the third outlet on the periphery of the outer ring region is excessive, releasing excessive gas outside the pot, this could ignite the outer periphery of the honeycomb body or even overflow, potentially causing a fire hazard to the user. The first, second, and third outlets are all fire holes in the honeycomb body. For ease of description, Figures 2-6 are collectively referred to as fire holes.

[0035] In a preferred embodiment of the present invention, the honeycomb body comprises: a metal strip 1, the metal strip 1 comprises a plurality of planar segments 11 and a plurality of corrugated segments 12, the planar segments 11 and the corrugated segments 12 are alternately connected, and the metal strip 1 is formed into a honeycomb body by winding.

[0036] The present application uses a single-layer metal strip having a flat section 11 and a corrugated section 12, and forms a regular corrugated shape by rolling or punching.

[0037] In the first case, the flat segment 11 and the corrugated segment 12 are connected alternately. The flat segment 11 can be located at the initial end of the metal strip 1. In this way, the end of the flat segment 11 is connected to the initial end of the corrugated segment 12. The initial end of the corrugated segment 12 is connected to the initial end of the next flat segment 11. The end of the next flat segment 11 is connected to the initial end of the next corrugated segment 12, and so on. Alternatively, the corrugated segment 12 can be located at the initial end of the metal strip 1 and then the flat segment 11 is provided. As long as the flat segment 11 and the corrugated segment 12 are provided alternately, it can be sufficient. It should be noted that the initial end of the metal strip 1 of this application is the side where the metal strip 1 is coiled, and the end corresponds to the initial end.

[0038] The second case is that the flat section 11 and the corrugated section 12 are not alternately connected, for example, the flat section 11 is located at the initial end of the metal thin strip 1, the second is the corrugated section 12, the third is still the corrugated section 12, the fourth is the flat section 11, the fifth is still the flat section 11, which is provided with one flat section 11 and one corrugated section 12 for one coiled circle 100. Alternatively, the flat section 11 is located at the initial end of the metal thin strip 1, the second is the corrugated section 12, the third is still the flat section 11, the fourth is the corrugated section 12, the fifth is still the corrugated section 12, the sixth is the flat section 11, the seventh is the corrugated section 12, the eighth is the flat section 11, the ninth is the flat section 11, and so on, that is, two flat sections 11 and two corrugated sections 12 for each coiled circle 100. Of course, when there are multiple flat sections 11 and multiple corrugated sections 12 on the coiled circle 100, the flat section 11 and the corrugated section 12 are not alternately connected at the connection between the adjacent two coiled circles 100, but are both the same shape, that is, both the corrugated section 12 or both the flat section 11.

[0039] By Figure 1 As can be seen from the honeycomb body shown in the figure, the honeycomb body also has a plurality of gas outlet rings. In the present application, the cooperation of the corrugated section 12 and the flat section 11 makes the corrugated section 12 as a gas outlet channel, and the plurality of corrugated sections 12 are uniformly distributed along the honeycomb body, which not only ensures uniform gas outlet, but also plays a role in stabilizing and uniformly distributing the airflow and reducing the generation of flue gas.

[0040] The metal thin strip 1 is coiled multiple times to form a honeycomb body, and the metal thin strip 1 forms a plurality of coiled circles 100 after coiling. Therefore, the honeycomb body of the present application is composed of a plurality of coiled circles 100 which are constrained to each other. In addition, the flat section 11 and the corrugated section 12 are constrained to each other, and there is no problem of local upward bulging or downward movement. The honeycomb body is not easy to warp and is not easy to cause tempering. The structure is simple and the cost is low.

[0041] In addition, the cross section of the honeycomb body can be circular, elliptical, triangular, rectangular, hexagonal, octagonal, dodecagonal, etc.

[0042] In a preferred embodiment of the present application, the metal thin strip 1 is coiled to form a plurality of coiled circles 100, and the coiled circles 100 include two types, one of which is a first coiled circle 100a formed by coiling the flat section 11 for one turn, and the other is a second coiled circle 100b formed by coiling the corrugated section 12 for one turn.

[0043] Among them, the first coiled circle 100a and the second coiled circle 100b are alternately arranged.

[0044] Figure 1As shown, in the present application, the planar segment 11 can be coiled once to form a first coil 100a, and the corrugated segment 12 can be coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b, and so on. Multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. In other words, each coil 100 in the honeycomb body represents a separate planar segment 11 or corrugated segment 12.

[0045] The innermost side of the honeycomb body may be the first coil 100a or the second coil 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after being wound once, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0046] Furthermore, the planar segment 11 can be wound multiple times as needed. Simply setting the length of the planar segment 11 and the number of turns required before pressing is sufficient. The lengths of the different planar segments 11 and corrugated segments 1212 can be calculated based on parameters such as the predetermined inner and outer diameters of the honeycomb, the thickness of the metal strip 1, and the wave height of the corrugated segment 12.

[0047] The first coils 100a and the second coils 100b of the present application are alternately arranged, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0048] In a preferred embodiment of the present invention, the metal strip 1 is wound to form a plurality of coils 100, and the coils 100 include a planar section 11 and a corrugated section 12. The outer side of the corrugated section 12 is the planar section 11 of the adjacent coil 100, and the outer side of the planar section 11 is the corrugated section 12 of the adjacent coil 100.

[0049] In a preferred embodiment of the present invention, each coil 100 includes at least one flat section 11 and at least one corrugated section 12 .

[0050] After the metal strip 1 is coiled, a plurality of coils 100 are formed. Each coil 100 can include a flat segment 11 and a corrugated segment 12 at the same time. No corresponding drawings are added to the specification. Each coil 100 has one flat segment 11 and one corrugated segment 12. Of course, two flat segments 11 and two corrugated segments 12 can also be set in each coil 100. Of course, the number of flat segments 11 and corrugated segments 12 on each coil 100 can also be 3, 4, 5, 6, 8, 9, 10, 12 or even more, and this application does not impose any restrictions on this.

[0051] As long as the outer rings of the flat sections 11 on adjacent coils 100 are formed by corrugated sections 12, and the outer rings of the corrugated sections 12 are formed by flat sections 11, that is, the flat sections 11 and corrugated sections 12 are arranged alternately from the inner ring to the outer ring, the flame holes are evenly distributed on the outlet surface, ensuring uniform gas output. Here, the flame holes are the wave segments on the corrugated section 12, and each wave segment can serve as a flame hole, ensuring uniform gas output, stable flames, and low smoke on the same outlet circle.

[0052] In a preferred embodiment of the present invention, an annular body is further included, wherein the metal strip 1 is coiled around the outer circumference of the annular body.

[0053] The initial end of the planar segment 11 can be connected to the outer periphery of the annular body, that is, the planar segment 11 is wrapped around the annular body in one circle or a section, or the corrugated segment 1212 can be directly coiled around the outer periphery of the annular body, which can increase the overall strength of the entire metal honeycomb body.

[0054] In a preferred embodiment of the present invention, the corrugated section 12 includes a plurality of wave crests 121 and a plurality of wave troughs 122 ; and a transition section 101 is provided between two adjacent coils 100 .

[0055] like Figure 1 As shown, the corrugation section 12 includes multiple peaks 121 and multiple troughs 122, wherein the peak near the starting end of the corrugation section 12 is the first peak, the trough near the starting end of the corrugation section 12 is the first trough, the peak near the end of the corrugation section 12 is the Nth peak, and the trough near the end of the corrugation section 12 is the Nth trough.

[0056] In such Figure 1 In the honeycomb body shown, part of the transition section 101 is connected between the first crest and the Nth crest on the same corrugated section 12, and the remaining part of the transition section 101 is connected between the first trough and the Nth trough. An irregular quadrilateral is formed by connecting the adjacent first winding coil 100a and the second winding coil 100b through two transitions, the first crest and the Nth crest, and the first trough and the Nth trough. The quadrilateral can be used to coil the corrugated section 12 into a whole, and the corrugated section 12 and the planar section 11 can be tightly connected to form a whole, thereby avoiding the problem of warping of the honeycomb body.

[0057] exist Figure 1In the honeycomb body shown, a transition section 101 is provided between two adjacent coils 100. Because the inner side of the coiled planar section 11 is in close contact with the outer periphery of the corrugated section 12 located on the inner circle, the first coiled coil 100 located on the inner side has the corrugated section 12 at the initial end and the planar section 11 at the end. When the planar section 11 is coiled toward the outer circle, it needs to coil from the trough 122 of the corrugated section 12 at the initial end to its crest 121, and continue to coil against the outer periphery of the corrugated section 12 to form the second coiled coil 100. Generally, the initial end of the second winding coil 100 is a flat section 11, and the end is a corrugated section 12. When the corrugated section 12 at the end of the winding coil 100 is wound to the third winding coil 100, the transition section 101 will be connected from the Nth wave peak of the second corrugated section 12 at the end of the second winding coil 100 to the first wave valley of the corrugated section 12 at the initial end of the third winding coil 100. At the same time, the inner side of the transition section 101 will abut against the first wave peak of the second corrugated section 12 at the initial end of the second winding coil 100. This cycle is repeated to form a tightly connected honeycomb body, thereby avoiding the problem of honeycomb body warping caused by local upward bulging or downward movement.

[0058] In a preferred embodiment of the present invention, the cross section of the corrugated section 12 is an arc-shaped wave, the wavelength of the arc-shaped wave is 0.2 mm to 3 mm, and the wave height of the arc-shaped wave is 0.1 mm to 2 mm.

[0059] like Figure 1 As shown, the corrugated segments 12 are regularly shaped bands, each wave being arc-shaped, and adjacent waves being of the same size and shape, forming a central symmetry. This results in an aesthetically pleasing honeycomb body, simple manufacturing, and uniform fire holes. Generally speaking, the waves of the corrugated segments 12 on the same outlet ring are of uniform size. Furthermore, the cross-section of the corrugated segments 12 can also be rectangular or triangular.

[0060] The advantage of using an arc wave is that when transitioning from one winding coil 100 to another, the wave crest at the end and the wave crest at the beginning of the unified air outlet ring after winding can overlap. Of course, in some cases, the two wave troughs may be close to or overlap and then enter the outer winding coil 100, making the entire honeycomb body more tightly connected and avoiding the problem of warping.

[0061] Of course, the wave sizes on the corrugated section 12 may also be different, especially the corrugated section 12 located on the inner circle and the corrugated section 12 located on its outer circle. The wave sizes may be different. For example, the fire holes in the outer circle may be larger than the fire holes in the inner circle. In some cases, the fire holes in the inner circle may be larger than the fire holes in the outer circle to increase the central firepower.

[0062] In a preferred embodiment of the present invention, there are multiple third air outlets, and the air outlet areas of the multiple third air outlets are the same.

[0063] like Figure 2As shown, the outlet areas of all third outlets in the outer ring area are the same, and are smaller than the outlet areas of the first outlets in the inner ring area. This allows the outer ring area to output less gas, allowing for quicker fire transfer without causing deflagration or shocking the user, thus improving user experience. It should be noted that deflagration occurs when the cookware is placed on the pot stand during ignition, creating a semi-enclosed space between the burner and the bottom of the pot. If temporary ignition occurs due to insufficient concentration in the inner ring, the outer ring nozzle is larger, releasing more gas outside the pot. If ignition is successful at this point, it can ignite the surrounding gas, including any gas that overflows outside the pot, shocking the user.

[0064] Figure 2 This is a coordinate diagram showing the changes in the outlet area of ​​the first, second and third outlets from the inner ring area, transition area to the outer ring area. For ease of description, the first, second and third outlets are collectively referred to as fire holes. Figure 2 The diagram shows the change of the area of ​​different single fire holes from the inner ring area to the outer ring area. It can also be understood as a schematic diagram of the change of the area of ​​multiple fire holes from the inside to the outside along the same radial direction of the honeycomb body. Figures 3-6 These are all graphs showing the area change from the inner ring area to the outer ring area for different single fire holes from the inside to the outside. In addition, Figures 2-6 In the figure, P1 is the dividing line between the inner ring area and the transition area, and P2 is the dividing line between the transition area and the outer ring area.

[0065] During specific processing, the changes in the areas of different fire holes can make the area of ​​the fire holes on each coil 100 the same. As the coil 100 increases outward, the area of ​​the fire hole can be changed by increasing the wave height of the corrugation on the corrugated section 12. Of course, the wavelength can also be changed or the wavelength or wave height can be changed at the same time. However, for the convenience of processing and the appearance of the fire hole, it is preferred to increase the wave height and change the area of ​​the fire hole.

[0066] In a preferred embodiment of the present invention, there are multiple third air outlets, and the air outlet areas of the multiple third air outlets decrease gradually from the inner side to the outer side of the outer ring area.

[0067] like Figure 3 As shown, all third outlets in the outer ring area have a smaller outlet area than the first outlet in the inner ring area, and the outlet areas of the multiple third outlets decrease from the inner side of the outer ring area to the outer side. In other words, the outlet area of ​​the third outlets located on the inner side of the outer ring area is larger than the outlet area of ​​the third outlets located on the outer side of the outer ring area. As the outlet areas of the multiple third outlets decrease from the inside to the outside, the gas concentration gradually decreases from the outside to the inside, which not only prevents deflagration but also increases the transmission rate and makes the flame more uniform.

[0068] Preferably, the change rate of the outlet area of ​​the multiple third outlets is 5%-20%. Within this range, the success rate and timeliness of fire transfer between the inner ring and the outer ring are high, and there is no backfire. The honeycomb body is evenly red, which can effectively improve thermal efficiency.

[0069] In a preferred embodiment of the present invention, there are multiple third air outlets, and the air outlet areas of the multiple third air outlets decrease in sections from the inner side to the outer side of the outer ring area.

[0070] like Figure 4 As shown, all the third air outlets in the outer ring area are smaller than the air outlet area of ​​the first air outlet in the inner ring area, and the air outlet areas of the multiple third air outlets decrease segmentally from the inner side to the outer side of the outer ring area. It can also be understood that the outer ring area includes multiple air outlet rings, each air outlet ring has multiple third air outlets, and the air outlet areas of the third air outlets on the same air outlet ring are the same, but the difference is that the air outlet area of ​​the third air outlet decreases once every 2 to 10 air outlet rings, so it appears as follows Figure 4 The flame hole area shown in the figure is reduced in sections. The present invention can not only avoid deflagration, but also increase the transmission rate and make the flame more uniform.

[0071] In a preferred embodiment of the present invention, the outlet area of ​​the second air outlet is equal to the outlet area of ​​the first air outlet.

[0072] The success rate or timeliness of the burner's flame transmission is very important. Failure to transmit the flame in time may also cause explosion due to excessive gas leakage. Figures 2-4 The outlet area of ​​the second air outlet in the transition area is the same as the outlet area of ​​the first air outlet in the inner ring area, which is beneficial to increasing the gas concentration in the combustion area and making it easier to transfer fire.

[0073] In a preferred embodiment of the present invention, there are multiple second air outlets, and the air outlet areas of the multiple second air outlets increase sequentially from the inner side to the outer side of the transition region.

[0074] like Figure 5 As shown, the outlet areas of the plurality of second air outlets increase successively from the inner side of the transition area to the outer side, and the outlet areas of the second air outlets are larger than the outlet areas of the first air outlets, which can effectively increase the fire transfer effect of the transition area.

[0075] In a preferred embodiment of the present invention, there are multiple first air outlets, and the air outlet areas of the multiple first air outlets increase sequentially from the inner side to the outer side of the inner ring area.

[0076] Figure 6As shown, the outlet area of ​​the first outlet in the inner ring region increases from the inside outward, which can increase the air output of the inner ring region from the inside outward. Because the ignition positions of some ignition pins are located on the periphery of the inner ring region, it is mainly necessary to ensure that the outlet air concentration around the ignition pins meets the requirements to avoid flashback caused by uneven air output around the ignition pins in the inner ring region.

[0077] A method for manufacturing a honeycomb body according to an embodiment of the present invention includes:

[0078] Selecting a metal strip 1 and determining basic parameters of a prefabricated honeycomb body;

[0079] Calculate the lengths of the flat section 11 and the corrugated section 12 based on the basic parameters of the honeycomb body;

[0080] According to the obtained lengths of the flat section 11 and the corrugated section 12 , a plurality of flat sections 11 and a plurality of corrugated sections 12 are pressed out on the metal strip 1 ; and then the metal strip 1 is wound multiple times to form a honeycomb body.

[0081] Among them, the pressing of the present application can be done by rolling, stamping, etc., as long as the flat segment 11 and the corrugated segment 12 can be formed on the metal strip 1 at the same time. The first case is that the flat segment 11 and the corrugated segment 12 are connected alternately. For example, the flat segment 11 is located at the initial end of the metal strip 1, and the end of the flat segment 11 is connected to the initial end of the corrugated segment 12. The initial end of the corrugated segment is connected to the initial end of the next flat segment 11, and the end of the next flat segment 11 is connected to the initial end of the next corrugated segment 12, and so on. At the same time, the initial end of the metal strip 1 can also be a corrugated segment 12 and then a flat segment 11 is set, as long as the flat segment 11 and the corrugated segment 12 are set alternately. It should be noted that the initial end of the metal strip 1 of the present application is the side where the metal strip 1 is coiled, and the end corresponds to the initial end. The second situation is that the flat segments 11 and the corrugated segments 12 are not alternately connected. For example, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a corrugated segment 12, the fourth segment may be a flat segment 11, and the fifth segment may also be a flat segment 11. This situation applies to the case where one coil 100 is provided with one flat segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a flat segment 11, the fourth segment may be a corrugated segment 12, the fifth segment may also be a corrugated segment 12, the sixth segment may be a flat segment 11, the seventh segment may be a corrugated segment 12, the eighth segment may be a flat segment 11, the ninth segment may be a flat segment 11, and so on. Each coil 100 has two flat segments 11 and two corrugated segments 12. Of course, when there are multiple planar segments 11 and multiple corrugated segments 12 on the winding coil 100, the connection between two adjacent winding coils 100 is not that the planar segments 11 and the corrugated segments 12 are alternately connected, but rather that they are two identical shapes, either both are corrugated segments 12 or both are planar segments 11.

[0082] The metal strip 1 is wound multiple times by the equipment to form a honeycomb body. After being wound, the metal strip 1 is formed into multiple coils 100. Therefore, the honeycomb body of the present application is composed of multiple mutually constrained coils 100, and the flat sections 11 and the corrugated sections 12 are alternately connected, so that the honeycomb body will not have the problem of local bulging (popping) upward or moving downward, and it is not easy to warp or cause tempering. It has a simple structure and low cost.

[0083] In a preferred embodiment of the present invention, the basic parameters of the honeycomb body include the inner diameter of the honeycomb body, the size of the fire holes, and the gas outlet direction.

[0084] In a preferred embodiment of the present invention, the pressing parameters include the length of the flat section 11, the length of the corrugated section 12, the inclination angle of the corrugated section 12, and the size of each wave in the corrugated section 12. The inclination angle of the corrugated section 12 and the size of each wave in the corrugated section 12 are determined based on the basic parameters of the honeycomb body and the thickness of the metal strip 1.

[0085] The basic parameters of the honeycomb body can be the inner diameter of the honeycomb body a, the circumference of the coil 100 S, the size of the fire hole. Since the fire hole of the present application is equivalent to each band of the corrugated section 12, the size of the fire hole is the wave height d and the wavelength c of the corrugated section 12. In addition, assuming that the thickness of the metal strip 1 is b, the circumference of the i-th coil 100 is S i ,but:

[0086] S i =π[a+(i-1)(b+d)].

[0087] Here, i represents the number from the inside to the outside, and the wave height is the height from the inner side of the wave crest 121 to the lowest point of the wave trough 122, that is, the distance from the highest point on the inner side of a wave crest 121 to the outer periphery of the plane segment 11 located on the inner side of the wave.

[0088] The lengths of different coils 100 can be calculated through the above process. When the flat section 11 and the corrugated section 12 are each wound around once to form a coil, the lengths of different coils 100 are the lengths of the flat section 11 and the corrugated section 12. If the coil 100 has m flat sections 11 and m corrugated sections 12, then the lengths of the flat section 11 and the corrugated section 12 are S. i / 2n, if the corrugated segment 12 is the initial end of the i-th winding circle, then the initial position of the first corrugated segment 12 of the i-th winding circle is S i-1 , the end position is S i-1 +S i / 2m, the initial position of the second corrugated section 12 of the next i-th circle is an S i-1 +S i / m, the end position is S i-1+S i 3 / 2m, and so on. Therefore, the initial position of different corrugated sections 12 can be determined. Then, the size of each wave in the honeycomb body can be determined according to the size of the fire hole.

[0089] The lengths of the different surface segments 11 and the corrugated segments 12 can be calculated through the above process. Based on the gas outlet direction of the fire holes in the honeycomb body, the inclination angle of the corrugated segments 12 can be calculated. The size of each wave in the honeycomb body can be determined based on the size of the fire holes.

[0090] Therefore, by inputting the above information into the control system, the control system can calculate and convert it into the pressing parameters of the pressing equipment, that is, the system can match the lengths of different plane segments 11 and corrugated segments 12, and can also calculate the shape and size of the waves in the corrugated segments 12 and the inclination angle of the corrugated segments 12, and then press the metal strip 1 according to these parameters.

[0091] In this application, the corrugated section 12 and the flat section 11 cooperate with each other, so that the waves on the corrugated section 12 serve as the air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet while also stabilizing the airflow pressure and evenly distributing it, thereby reducing the generation of smoke.

[0092] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, oval, triangle, rectangle, hexagon, octagon, dodecagon, etc., and this application does not impose any limitation on this.

[0093] In a preferred embodiment of the present invention, the planar section 11 is coiled once to form a first coil 100a, and the corrugated section 12 is coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b. A honeycomb body is formed by alternating a plurality of first coils 100a and second coils 100b.

[0094] In a preferred embodiment of the present invention, one of the first coil 100a or the second coil 100b is disposed at the innermost side of the honeycomb body.

[0095] Figure 1 As shown, in the present application, the planar segment 11 can be coiled once to form a first coil 100a, and the corrugated segment 12 can be coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b, and so on. Multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. In other words, each coil 100 in the honeycomb body represents a separate planar segment 11 or corrugated segment 12.

[0096] The innermost side of the honeycomb body may be the first coil 100a or the second coil 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after being wound once, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0097] Furthermore, the planar segment 11 can be wound multiple times as needed. Simply setting the length of the planar segment 11 and the number of turns required before pressing is sufficient. The lengths of the different planar segments 11 and corrugated segments 12 can be calculated based on parameters such as the predetermined inner and outer diameters of the honeycomb, the thickness of the metal strip 1, and the wave height of the corrugated segments 12.

[0098] The first coils 100a and the second coils 100b of the present application are alternately arranged, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0099] In a preferred embodiment of the present invention, the lengths of the flat section 11 and the corrugated section 12 are adjusted so that each winding coil 100 has both a flat section 11 and a corrugated section 12, and the outer side of the corrugated section 12 is the flat section 11 of the adjacent winding coil 100, and the outer side of the flat section 11 is the corrugated section 12 of the adjacent winding coil 100.

[0100] Each coil 100 may be composed of one flat segment 11 and one corrugated segment 12. Each coil 100 may have two flat segments 11 and two corrugated segments 12. Of course, the number of flat segments 11 and corrugated segments 12 on each coil 100 may also be 3, 4, 5, 6, 8, 9, 10, 12, or even more. This application does not impose any limitation thereto.

[0101] When pressing the metal strip 1, it is only necessary to calculate the length of each flat segment 11 and corrugated segment 12 based on the inner and outer diameters of the honeycomb body, the number of flat segments 11 and corrugated segments 12 on each winding ring 100, the thickness of the metal strip 1, the wave height and wavelength of the corrugated segment 12. The system calculates the length of each flat segment 11 and corrugated segment 12 according to the relationship between the different inner and outer diameters, and then inputs it into the control system. The control system controls, for example, a roller press to perform rolling according to the set program, and then outputs the flat segment 11 and corrugated segment 12 on a metal strip 1.

[0102] In this application, the outer rings of the flat sections 11 on adjacent coils 100 are formed into corrugated sections 12, and the outer rings of the corrugated sections 12 are formed into flat sections 11. That is, the flat sections 11 and corrugated sections 12 are arranged alternately from the inner ring to the outer ring, ensuring that the flame holes are evenly distributed on the outlet surface, ensuring uniform gas output. Here, the flame holes are the wave segments on the corrugated section 12, and each wave segment can serve as a flame hole. This results in uniform gas output on the same outlet circle, a stable flame, and low smoke.

[0103] In a preferred embodiment of the present invention, the planar segment 11 is coiled around the outer circumference of the annular body; alternatively, the corrugated segment 12 is coiled around the outer circumference of the annular body. The planar segment 11 can be coiled one or more times to increase the thickness of the honeycomb's inner wall and improve its overall compressive strength. The corrugated segment 12 can also be coiled around the outer circumference of the pile body 2. The annular body in this application can be a steel ring or other annular object.

[0104] The specific operation is: use a small flat segment 11 to connect with the annular body, or directly use a corrugated belt to connect with the annular body, and then wind it to form a honeycomb body. You can also use an annular body to replace the first flat segment 11, connect the corrugated segment 12 to the outer periphery of the steel ring, and then wind the flat segment 11 connected to the corrugated segment 12 around the outer periphery of the corrugated segment 12 to finally form a honeycomb body.
