[0004] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0005] According to one aspect of the present invention, a honeycomb body is provided. The honeycomb body comprises a thin metal strip comprising a plurality of planar segments and a plurality of corrugated segments, the metal strip being coiled to form the honeycomb body. The planar segments and the corrugated segments cooperate to form air outlet holes in the honeycomb body. The air outlet holes are arranged in an inclined direction, and the area of ​​the air outlet holes located on the outer periphery of the honeycomb body is smaller than the area of ​​the air outlet holes located on the inner periphery of the honeycomb body.

[0010] The inclination angle of the air outlet located in the inner ring area is α2, 5°≤α2≤30°;

[0011] Among them, α2≤α1.

[0012] According to an embodiment of the present invention, there are a plurality of the air outlet holes located in the outer ring area, and the air outlet areas of the plurality of air outlet holes are the same.

[0013] According to an embodiment of the present invention, there are a plurality of the air outlet holes located in the outer ring area, and the air outlet areas of the plurality of air outlet holes decrease from the inside to the outside.

[0034] 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.

[0035] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0036] A honeycomb body according to an embodiment of the present invention comprises: a metal strip 1, the metal strip 1 comprising a plurality of planar segments 11 and a plurality of corrugated segments 12, the planar segments 11 and the corrugated segments 12 being alternately connected, the metal strip 1 being coiled to form a honeycomb body, wherein the planar segments 11 and the corrugated segments 12 are coordinated to form air outlet holes 10 of the honeycomb body, the air outlet directions of the air outlet holes 10 are inclined to the central axis of the honeycomb body, and the area of ​​the air outlet holes 10 located on the outer periphery of the honeycomb body is smaller than the area of ​​the air outlet holes 10 located on the inner periphery of the honeycomb body.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] pass Figure 1 It can be seen from the honeycomb body shown that the honeycomb body also has multiple air outlet rings. In this application, the corrugated section 12 and the flat section 11 are used in conjunction with each other so that the waves on the corrugated section 12 serve as air outlet channels. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet while also stabilizing and evenly distributing the airflow and reducing the generation of smoke.

[0041] The metal strip 1 is coiled multiple times to form a honeycomb body. After the metal strip 1 is coiled, multiple coils 100 are formed. Therefore, the honeycomb body of the present application is composed of multiple mutually constrained coils 100. In addition, the flat section 11 and the corrugated section 12 are constrained to each other, and there will be no problem of local protrusion upward or downward movement. The honeycomb body is not easy to warp or cause tempering, and has a simple structure and low cost.

[0042] The area of ​​the air outlet holes 10 located at the outer periphery of the honeycomb body is smaller than the area of ​​the air outlet holes 10 located at the inner periphery of the honeycomb body. In this application, the area located at the outer periphery of the honeycomb body refers to the part close to the outermost side of the honeycomb body, and the area located at the inner periphery of the honeycomb body refers to the part close to the inner peripheral surface of the honeycomb body. Taking the double-ring burner as an example, the area located at the outer periphery of the honeycomb body refers to the part on the outer side of the outer ring, and the area located at the inner periphery of the honeycomb body refers to the part of the inner ring close to the inner peripheral surface of the honeycomb body. In addition, the part of the outer ring close to the inner ring may be larger than or equal to the air outlet holes 10 in the inner ring area. In this application, by making the area of ​​the air outlet holes 10 located at the outer periphery of the honeycomb body smaller than the area of ​​the air outlet holes 10 located at the inner periphery of the honeycomb body, the gas concentration at the inner ring or ignition needle can be increased, which is beneficial to improving the ignition success rate and the ignition speed can also be faster. It can avoid temporary ignition due to insufficient concentration in the inner ring during ignition. The outer ring nozzle is larger and releases more gas to the outside of the pot. If ignition is suddenly successful at this time, it will ignite the surrounding gas and scare the user.

[0043] Each wave segment in the corrugated segment 12 and the corresponding plane segment 11 form an air outlet 10. The air outlet direction of the air outlet 10 is inclined, which can increase the flow time of the gas or mixed gas and improve the heat exchange effect of the gas or mixed gas.

[0044] Due to the different inclination directions of the gas outlet 10 and the inclination angles of the channels, the resistance to the gas will also be different, and the gas outlet speed at the fire hole will also be different. The smaller the inclination angle, the greater the gas outlet concentration / speed. The preferred inclination angle of the gas outlet channel increases from the inside to the outside, which can increase the gas outlet concentration / speed around the honeycomb body and gradually decrease outward, making it easier to ignite and transmit fire. This can avoid temporary ignition due to insufficient concentration in the inner ring during ignition. The outer ring nozzle is larger, releasing more gas to the outside of the pot. If ignition is suddenly successful at this time, it will ignite the surrounding gas and scare the user.

[0045] The air outlet 10 of the present application can be a regular shape such as a triangle, an arc, a rectangle, a trapezoid, a hexagon, an octagon, etc. Since the air outlet direction of the air outlet 10 is parallel to the central axis of the air outlet 10, the angle between the central axis of the air outlet 10 and the plane where the top surface of the honeycomb body is located is referred to as the inclination angle of the air outlet 10.

[0046] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc.

[0047] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100. The coils 100 include two types: a first coil 100a formed by coiling the flat section 11, and a second coil 100b formed by coiling the corrugated section 12.

[0048] The first winding coils 100a and the second winding coils 100b are alternately arranged.

[0049] Figure 1-2 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.

[0050] The innermost side of the honeycomb body may be the first coil 100a or the second coil 100b. Figure 1The 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 .

[0055] 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.

[0056] As long as the outer ring of the flat section 11 on adjacent coils 100 is a corrugated section 12, and the outer ring of the corrugated section 12 is a flat section 11, that is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner ring to the outer ring, the outlet holes are evenly distributed on the outlet surface, ensuring uniform air outlet. Here, the outlet holes are the wave segments on the corrugated section 12, and each wave can serve as an outlet hole, ensuring uniform air outlet, stable flame, and less smoke.

[0057] 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.

[0058] The initial end of the planar segment 11 can be connected to the outer periphery of the annular body, that is, a circle or a section of the planar segment 11 is wrapped around the annular body, 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.

[0059] 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 .

[0060] In such Figure 1-2 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.

[0061] In such Figure 1-2 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.

[0062] exist Figure 1-2 In 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.

[0063] In a preferred embodiment of the present invention, the corrugated section 12 is a corrugation inclined to the overall extension direction of the metal strip 1, so that the gas outlet direction of the air hole 10 is inclined.

[0064] like Figure 1 As shown, the outlet channel of the corrugated section 12 is inclined relative to the overall extension direction of the metal strip 1. In other words, the outlet channel of the corrugated section 12 is tilted. Compared with conventional vertical outlet channels, this provides a longer channel, which increases the flow time of the gas or mixed gas and improves the heat exchange effect of the gas or mixed gas. Furthermore, the inclined shape of the corrugated section 12 increases the cross-sectional area of ​​the channel, which improves the heat radiation effect.

[0065] In a preferred embodiment of the present invention, the inclination angle of the outlet direction of the air outlet hole 10 is α, wherein 5°≤α≤45°.

[0066] like Figure 1 and 8 As shown, the inclination angle of the corrugated section 12 in this application is the angle between the inclination direction of the corrugated section 12 and the overall extension direction of the metal strip 1. The inclination direction of the corrugated section 12 is arranged to tilt upward. When the angle is 5°≤α≤45°, the gas encounters less resistance, which can increase heat exchange and improve heat radiation.

[0067] In a preferred embodiment of the present invention, the honeycomb body is provided with an inner ring region, a transition region and an outer ring region from the inside to the outside, and the inclination angle of the air outlet in the transition region is equal to the inclination angle of the air outlet in the inner ring region.

[0068] like Figure 1 and 8 As shown, by making the inclination angle of the corrugated section 12 in the transition area the same as the inclination angle of the corrugated section 12 in the inner ring area, fire transfer is facilitated, explosion is avoided, and user experience is improved.

[0069] The honeycomb body of the present application can be used in a double-ring burner, wherein the inner ring region corresponds to the inner ring fire, and the transition region and the outer ring region correspond to the outer ring fire; the honeycomb body of the present application can be used in a triple-ring burner having three gas supply channels, wherein the inner ring region, the transition region, and the outer ring region correspond to the three gas supply channels respectively. It should be noted that Figure 3 The coordinate diagram of the change of the outlet area of ​​the outlet hole 10 from the inner ring area, the transition area to the outer ring area can be understood as Figure 2 The diagram shows the change of the outlet area of ​​multiple single outlet holes 10 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 outlet holes 10 from the inside to the outside along the same radial direction of the honeycomb body. Figure 3-7It is also a diagram showing the area change of a single air outlet 10 from the inside to the outside in the direction from the inner ring area to the outer ring area. Figure 3-8 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. Figure 3-8 The middle transition region is abbreviated as transition zone.

[0070] In a preferred embodiment of the present invention, the inclination angle of the air outlet holes located in the outer ring area is α1, 30°≤α1≤45°;

[0071] The inclination angle of the air outlet located in the inner ring area is α2, 5°≤α2≤30°;

[0072] Among them, α2≤α1.

[0073] like Figure 8 As shown, the inclination angles of the air outlets in the outer ring area and the inner ring area are different. The inclination angle of the air outlet in the inner ring area is smaller than that of the air outlet in the outer ring area, that is, α2<α1. This can increase the air outlet velocity concentration in the inner ring area, which is beneficial to ignition. It can avoid temporary ignition due to insufficient concentration in the inner ring during ignition. The outer ring nozzle is larger and releases more gas to the outside of the pot. If the ignition is suddenly successful at this time, it will ignite the surrounding gas, including the gas overflowing outside the pot, which will scare the user.

[0074] In the range of 30°≤α1≤45° and 5°≤α2≤30°, the outlet gas concentration not only meets the process requirements of the burner, but also increases the heat radiation of the honeycomb body and improves the thermal efficiency.

[0075] The resistance encountered by the gas passing through the corrugated section 12 will also be different, and the gas outlet velocity at the fire hole will also be different. When the inclination angle α2 of the corrugated section 12 in the inner ring area is greater than or equal to 5° and less than or equal to 30°, the gas outlet velocity and gas concentration will increase, which is beneficial to improving the thermal radiation of the honeycomb body.

[0076] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the outer ring area, and the air outlet areas of the multiple air outlet holes 10 are the same.

[0077] like Figure 3As shown, the gas outlet holes 10 in the outer ring area 2 are all the same size, and the area of ​​the gas outlet holes 10 in the outer ring area is smaller than that of the gas outlet holes 10 in the inner ring area. In this way, the amount of gas output by the outer ring area is small, and the fire is transferred in a short time, which will not cause explosions and will not scare users, thereby improving the user experience. It should be noted that explosions occur because when the pot is placed on the pot stand at the time of ignition, the burner and the bottom of the pot form a semi-enclosed space. When ignition occurs, if the concentration in the inner ring is insufficient and temporary ignition occurs, the outer ring nozzle is larger, releasing more gas to the outside of the pot. If ignition is suddenly successful at this time, it will ignite the surrounding gas, including the gas overflowing outside the pot, which will scare the user.

[0078] The area of ​​the air outlet hole 10 appearing in this application is also the air outlet area of ​​the air outlet hole 10 .

[0079] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the outer ring area, and the air outlet areas of the multiple air outlet holes 10 decrease from the inside to the outside.

[0080] like Figure 4 As shown, the area of ​​the air outlet holes 10 in the outer ring area is smaller than that of the air outlet holes 10 in the inner ring area, and the area of ​​the air outlet holes 10 in the outer ring area decreases from the inside to the outside. In this way, the concentration of the gas output by the burner gradually decreases from the outside to the inside, which can not only avoid deflagration, but also increase the transmission rate and make the flame more uniform.

[0081] Preferably, the reduction rate of the area of ​​the air outlet holes 10 in the outer ring region 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 reddened, which can effectively improve thermal efficiency.

[0082] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the outer ring area, and the air outlet areas of the multiple air outlet holes 10 decrease in sections from the inside to the outside.

[0083] like Figure 5 As shown, the area of ​​the air outlet holes 10 in the outer ring area is smaller than that in the inner ring area, and the area of ​​the air outlet holes 10 in the outer ring area decreases from the inside to the outside, which can not only avoid deflagration, but also increase the transmission rate and make the flame more uniform.

[0084] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the inner ring area, and the air outlet areas of the multiple air outlet holes 10 are equal to the air outlet area of ​​the air outlet holes 10 located in the transition area.

[0085] 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. Figure 2-4The outlet area of ​​the air outlet holes 10 in the transition area is the same as that of the air outlet holes 10 in the inner ring area, which is beneficial to increasing the gas concentration in the combustion area and making it easier to transfer fire.

[0086] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the transition area, and the air outlet areas of the multiple air outlet holes 10 increase from the inside to the outside.

[0087] like Figure 6 As shown, the outlet area of ​​the air outlet holes 10 located in the transition area increases from the inside to the outside, thereby increasing the gas concentration in the transition area and effectively improving the flame transfer effect in the combustion area.

[0088] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 in the inner ring area, and the areas of the multiple air outlet holes 10 increase from the inside to the outside.

[0089] like Figure 7 As shown, the cross-sectional area of ​​the air outlet holes 10 in the inner ring region increases from the inside outward, thereby increasing the air output of the inner ring region from the inside outward. Since 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 air outlet concentration around the ignition pins meets the requirements to avoid flashback caused by uneven air outlet around the ignition pins in the inner ring region.

[0090] like Figure 3-7 As shown, the cross-sectional area of ​​the air outlet 10 in the inner ring region includes two cases, the first case is that the area of ​​the air outlet 10 remains unchanged, and the second case is that the area of ​​the air outlet 10 increases from the inside to the outside. The outlet area of ​​the air outlet 10 in the transition region includes two cases, the first case is that the area of ​​the air outlet 10 remains unchanged, and the second case is that the area of ​​the air outlet 10 increases from the inside to the outside. The area of ​​the air outlet 10 in the outer ring region includes three cases: the first case is that the area of ​​the air outlet 10 remains unchanged, the second case is that the area of ​​the air outlet 10 decreases from the inside to the outside, and the third case is that the area of ​​the air outlet 10 decreases with equal gradients. Different honeycomb bodies can be formed by any combination of the above cases, and all of them can achieve rapid ignition and fire transfer without the problem of deflagration.

[0091] In a preferred embodiment of the present invention, the cross section of the corrugated section 12 is a triangular wave, the wavelength of the triangular wave is 0.2 mm to 3 mm, and the wave height of the triangular wave is 0.1 mm to 2 mm.

[0092] like Figure 1-2 As shown, the corrugated segments 12 are regularly shaped bands, each triangular in shape. Adjacent waves are of the same size and shape, forming a central symmetry. This results in an aesthetically pleasing honeycomb structure, simple manufacturing, and uniform air outlet pores. Generally, the waves of the corrugated segments 12 on the same outlet ring are of uniform size. Furthermore, the cross-sections of the corrugated segments 12 can also be trapezoidal, rectangular, or arcuate.

[0093] 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 air outlet of the outer circle may be larger than the air outlet of the inner circle. In some cases, the air outlet of the inner circle may be larger than the air outlet of the outer circle to increase the central firepower.

[0094] A method for manufacturing a honeycomb body according to an embodiment of the present invention includes:

[0095] Selecting a metal strip 1 and determining basic parameters of a prefabricated honeycomb body;

[0096] Calculate the lengths of the flat section 11 and the corrugated section 12 based on the basic parameters of the honeycomb body;

[0097] 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.

[0098] Among them, the pressing of this application can be rolling, stamping and the like, as long as the flat section 11 and the corrugated section 12 can be formed on the metal strip 1 at the same time, wherein the corrugated section 12 is a corrugation inclined to the metal strip 1, so that the outlet direction of the air outlet 10 is inclined, which can increase the flow time of the gas or mixed gas and improve the heat exchange effect of the gas or mixed gas.

[0099] Furthermore, the present invention utilizes a thin metal strip 11 wound multiple times to form a honeycomb body. The thin metal strip 11 is wound into multiple coils 100. Therefore, the honeycomb body of the present invention is composed of multiple mutually constrained coils 100, with the planar segments 11 and corrugated segments 12 alternately connected. This prevents the honeycomb body from experiencing localized upward bulging (popping) or downward movement, and is less susceptible to warping and tempering. The structure is simple and low-cost. The specific coil structure is as follows:

[0100] The first case is that the flat section 11 and the corrugated section 12 are connected alternately. For example, the flat section 11 is located at the initial end of the metal strip 1, and the end of the flat section 11 is connected to the initial end of the corrugated section 12. The initial end of the corrugated section is connected to the initial end of the next flat section 11, and the end of the next flat section 11 is connected to the initial end of the next corrugated section 12, and so on. At the same time, the corrugated section 12 can also be located at the initial end of the metal strip 1 and then the flat section 11 is set, as long as the flat section 11 and the corrugated section 12 are arranged alternately. 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. 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.

[0101] 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 gas outlet holes 10 and the gas outlet direction.

[0102] 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 direction of the corrugations in the corrugated section 12, and the size of each wave in the corrugated section 12. The inclination direction of the corrugations in 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.

[0103] 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 outlet hole. Since the outlet hole of the present application is equivalent to each wave of the corrugated section 12, the size of the outlet 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:

[0104] S i =π[a+(i-1)(b+d)].

[0105] 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.

[0106] 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 positions of the different corrugation segments 12 can be determined. The size of each wave in the honeycomb can then be determined based on the size of the outlet holes 10. The inclination angle of the corrugation can be calculated based on the outlet direction of the outlet holes in the honeycomb. The size of each wave in the honeycomb can also be determined based on the size of the outlet holes 10.

[0107] 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.

[0108] 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.

[0109] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc., and this application does not impose any limitation thereto.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In this application, the outer ring of the flat section 11 on adjacent coils 100 is a corrugated section 12, and the outer ring of the corrugated section 12 is a flat section 11. That is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner ring to the outer ring, ensuring that the outlet holes are evenly distributed on the outlet surface, ensuring uniform air outlet. Here, the outlet holes are the wave segments on the corrugated section 12, and each wave can serve as an outlet hole, ensuring uniform air outlet, stable flame, and less smoke.

[0120] 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 inner wall and improve the overall compressive strength. The corrugated segment 12 can also be coiled around the outer circumference of the annular body. The annular body in this application can be a steel ring or other annular object.

[0121] 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.
