[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0041] The terms "a", "an", "the", "" 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.

[0042] A honeycomb body according to an embodiment of the present invention comprises: a metal thin strip 1, wherein the metal thin strip 1 comprises a plurality of planar segments 11 and a plurality of corrugated segments 12, and the metal thin strip 1 is formed into a honeycomb body by winding.

[0043] The air outlet holes 10 of the honeycomb body are formed by the cooperation of the plane section 11 and the corrugated section 12; the air outlet area of ​​the air outlet holes 10 located at the outer periphery of the honeycomb body is smaller than the air outlet area of ​​the air outlet holes 10 located at the inner periphery of the honeycomb body.

[0044] Among them, after the metal strip 1 is coiled, the plane section 11 and the corrugated section 12 will appear alternately inside and outside. For example, when a certain coiled circle 100 is a plane section 11 or one end of a certain coiled circle 100 is a plane section 11, the outer periphery of the plane section 11 will coil around the corrugated section 12, so that an air outlet channel can be formed between the plane section 11 and the corrugated section 12, and the corrugated section 12 and the inner periphery or outer periphery of the plane section 11 form an air outlet hole 10, that is, each wave in the corrugated section 12 can be surrounded by the plane section 11 to form an air outlet channel, so it can be understood that each wave in the corrugated section 12 is an air outlet hole 10. The present application makes the air outlet area of ​​the air outlet hole 10 more uniform through the cooperation of the plane section 11 and the corrugated section 12, and the tempering phenomenon will not occur.

[0045] In the present application, the outlet area of ​​the air outlet holes 10 located at the outer periphery of the honeycomb body is smaller than the outlet area of ​​the air outlet holes 10 located at the inner periphery of the honeycomb body. In the present application, the air outlet holes 10 located at the outer periphery of the honeycomb body refer to the part close to the outermost part of the honeycomb body, and the air outlet holes 10 located at the inner periphery of the honeycomb body refer to the part close to the inner circumference of the honeycomb body. Taking the double-ring burner as an example, the air outlet holes 10 located at the outer periphery of the honeycomb body refer to the part outside the outer ring, and the air outlet holes 10 located at the inner periphery of the honeycomb body refer to the part close to the inner circumference 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.

[0046] The present application increases the gas concentration at the inner ring or ignition needle by making the gas outlet area of ​​the gas outlet holes 10 located on the outer periphery of the honeycomb body smaller than the gas outlet area of ​​the gas outlet holes 10 located on the inner periphery of the honeycomb body, which is beneficial to increase the ignition success rate and ignition speed. 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 successful at this time, it will ignite the surrounding gas and scare the user.

[0047] The present application adopts a single-layer metal strip 1 having both a flat section 11 and a corrugated section 12, and forms a regular corrugated shape by rolling or punching.

[0048] The first case is that the plane segment 11 and the corrugated segment 12 are connected alternately, and the plane segment 11 can be located at the initial end of the metal strip 1, so that the end of the plane segment 11 is connected to the initial end of the corrugated segment 12, and the initial end of the corrugated segment 12 is connected to the initial end of the next plane segment 11, and the end of the next plane segment 11 is connected to the initial end of the next corrugated segment 12, and so on. It can also be that the corrugated segment 12 can be located at the initial end of the metal strip 1 and then the plane segment 11 is set, as long as the plane 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 opened for winding, and the end corresponds to the initial end.

[0049] The second situation is that the plane segment 11 and the corrugated segment 12 are not connected alternately. For example, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the corrugated segment 12, the fourth segment is the plane segment 11, and the fifth segment is still the plane segment 11. This situation is for a coil 100 provided with one plane segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be the plane segment 11, the second segment is the corrugated segment 12, the third segment is still the plane segment 11, the fourth segment is the corrugated segment 12, the fifth segment is still the corrugated segment 12, the sixth segment is the plane segment 11, the seventh segment is the corrugated segment 12, the eighth segment is the plane segment 11, the ninth segment is the plane segment 11, and so on. This situation can be referred to Figure 2 Each coil 100 has two plane segments 11 and two corrugated segments 12. Of course, when there are multiple plane segments 11 and multiple corrugated segments 12 on the coil 100, the plane segments 11 and the corrugated segments 12 are not connected alternately at the connection of two adjacent coils 100, but are two identical shapes, either all of which are corrugated segments 12 or all of which are plane segments 11.

[0050] pass Figure 1 It can be seen from the honeycomb body shown that the honeycomb body also has a plurality of air outlet rings. In the present 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 air outlet channels. The plurality of corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet and can also stabilize and evenly distribute the airflow and reduce the generation of smoke.

[0051] 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 bulging upward or moving downward. The honeycomb body is not easy to warp or cause tempering, and has a simple structure and low cost.

[0052] In addition, the cross-section of the honeycomb body can be in various shapes such as circular, elliptical, rectangular, rectangular, hexagonal, octagonal, dodecagonal, etc.

[0053] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100, and the coils 100 include two types, one of which is a first coil 100a formed by coiling the flat section 11, and the other is a second coil 100b formed by coiling the corrugated section 12.

[0054] The first winding coils 100a and the second winding coils 100b are arranged alternately.

[0055] Figure 1As shown, the present application can form a first coiled circle 100a by coiling the plane segment 11 once, and form a second coiled circle 100b by coiling the corrugated segment 12 once, and the outer circle of the first coiled circle 100a is provided with the second coiled circle 100b, and the outer circle of the second coiled circle 100b is provided with the first coiled circle 100a, and so on, and multiple first coiled circles 100a and second coiled circles 100b are alternately arranged to form a honeycomb body. That is, each coiled circle 100 in the honeycomb body is a separate plane segment 11 or corrugated segment 12.

[0056] The innermost side of the honeycomb body may be the first winding circle 100a or the second winding circle 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after winding one circle, 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.

[0057] In addition, the plane section 11 can be wound for multiple turns as required, and the length of the plane section 11 and the number of turns after winding can be set before pressing. The lengths of different plane sections 11 and corrugated sections 1212 can be calculated based on the preset inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, the wave height of the corrugated section 12 and other parameters.

[0058] The first winding coils 100a and the second winding coils 100b of the present application are arranged alternately, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first winding coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0059] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100, and the coils 100 include a planar section 11 and a corrugated section 12, wherein the outer side of the corrugated section 12 is the planar section 11 of an adjacent coil 100, and the outer side of the planar section 11 is the corrugated section 12 of an adjacent coil 100.

[0060] 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 .

[0061] After the metal strip 1 is coiled, a plurality of coiled circles 100 are formed. Each coiled circle 100 may include a plane segment 11 and a corrugated segment 12 at the same time. No corresponding drawings are added to the specification. Each coiled circle 100 has one plane segment 11 and one corrugated segment 12. Of course, two plane segments 11 and two corrugated segments 12 may also be provided in each coiled circle 100. Of course, the number of plane segments 11 and corrugated segments 12 on each coiled circle 100 may also be 3, 4, 5, 6, 8, 9, 10, 12 or even more, and the present application does not impose any limitation thereto.

[0062] As long as the outer circle of the flat section 11 on the adjacent winding ring 100 is the corrugated section 12, and the outer circle of the corrugated section 12 is the flat section 11, that is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner circle to the outer circle, it is ensured that the outlet holes 10 are evenly distributed on a gas outlet surface, and the gas outlet is uniform. Here, the outlet holes are the bands on the corrugated section 12, and each band can be used as an outlet hole. The honeycomb body of the present application has stable flame and less smoke.

[0063] In a preferred embodiment of the present invention, it further comprises an annular body, wherein the metal strip 1 is coiled around the outer circumference of the annular body.

[0064] 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 for one circle or one 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.

[0065] In a preferred embodiment of the present invention, the cross section of the corrugated section 12 is a rectangular wave, the wavelength of the rectangular wave is 0.2 mm to 3 mm, and the wave height of the rectangular wave is 0.1 mm to 2 mm.

[0066] like Figure 1 As shown, the corrugated section 12 is a regular shape band, each wave is rectangular, and the size and shape of adjacent waves are consistent and centrally symmetrical, so that the honeycomb body is beautiful, the process is simple, and the air outlet holes are uniform. Generally speaking, the wave size of the corrugated section 12 on the same air outlet ring is consistent. In addition, the cross section of the corrugated section 12 can also be an arc wave, a triangular wave, or a trapezoidal wave.

[0067] Of course, the wave sizes on the corrugated segment 12 may also be different, especially the corrugated segment 12 located on the inner circle and the corrugated segment 12 located on its outer circle. The wave sizes may be different. For example, the air outlet holes in the outer circle may be larger than the air outlet holes in the inner circle. In some cases, the air outlet holes in the inner circle may be larger than the air outlet holes in the outer circle to increase the central firepower.

[0068] The preferred corrugated section 12 includes a plurality of crests 121 and a plurality of troughs 122, such as Figure 1 As shown, the crest near the starting end of the corrugation segment 12 is the first crest, the trough near the starting end of the corrugation segment 12 is the first trough, the crest near the end of the corrugation segment 12 is the Nth crest, and the trough near the end of the corrugation segment 12 is the Nth trough.

[0069] Taking the example in which the flat section 11 is first coiled around to form the first coiling circle 100a, and then the corrugated section 12 is coiled around the outer periphery of the first coiling circle 100a, when coiling the next corrugated section 12, it is only necessary to make the width of the hole between the last wave and the first wave of the corrugated section 12 smaller and the height higher than the previous width of the metal strip 1, so as to ensure the outlet area of ​​the air outlet 10 and make the inner and outer coiling circles 100 fit better, thereby improving the cavity of the entire honeycomb body and avoiding deformation and warping problems.

[0070] In a preferred embodiment of the present invention, the honeycomb body is provided with at least two annular regions, and transition zones are provided between two adjacent annular regions to increase the fire transfer effect between adjacent annular regions. When the burner is installed, in order to facilitate the correspondence with different air supply channels on the burner, a partition can be provided on the honeycomb body to divide the honeycomb body into at least two annular regions. The partition can be an annular partition or a cylinder that cooperates with a fire divider to form a double ring fire or a multi-ring fire. For the sake of illustration, this application takes a double ring as an example and sets the partition as follows: Figure 2-7 At the point P shown, the honeycomb body forms inner and outer ring regions.

[0071] In a preferred embodiment of the present invention, there are two annular regions, namely an inner annular region and an outer annular region, and a transition region connects the inner annular region and the outer annular region.

[0072] like Figure 2-7 As shown, the general burner is two-ring or multi-ring, and the ignition needle is in the inner ring. By enlarging the inner ring fire hole and increasing the gas concentration at the inner ring or ignition needle, it is beneficial to improve the ignition success rate and ignition speed. When the burner can ignite quickly, the amount of gas leaked from the outer ring is small, and the transition zone can complete the fire transfer in a short time, which will not cause deflagration and will not scare users, thus improving user experience.

[0073] 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.

[0074] like Figure 2 As shown, all the air outlet holes 10 in the outer ring area are the same size, and the air outlet area of ​​the air outlet holes 10 in the outer ring area is smaller than the air outlet area of ​​the air outlet holes 10 in the inner ring area. In this way, the amount of gas output from the outer ring area is small, and the fire transfer is completed in a short time, which will not cause deflagration and will not scare the user, thereby improving the user experience. It should be noted that deflagration occurs when the pot is placed on the pot support at the time of ignition, and the burner and the bottom of the pot form a semi-enclosed space. When ignition occurs, if temporary ignition occurs due to insufficient concentration in the inner ring, the outer ring nozzle is larger, releasing 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.

[0075] Figure 2 The coordinate diagram is a diagram showing the change of the outlet area of ​​the outlet hole 10 from the inner ring area, the transition area to the outer ring area. For the convenience of description, the "outlet area of ​​the outlet hole 10" in the figure description is simplified to the fire hole area, which can be understood as Figure 2 The schematic diagram shows the change of the area of ​​multiple single outlet holes 10 from the inner ring area to the outer ring area from the inside to the outside. 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. It should be noted that Figure 3-6 These are all graphs showing the change in the outlet area of ​​the multiple outlet holes 10 distributed from the inner ring area to the outer ring area from the inside to the outside. In addition, Figure 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.

[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 decrease from the inside to the outside.

[0077] like Figure 3 As shown, the outlet area of ​​the outlet holes 10 in the outer ring area is smaller than that of the outlet holes 10 in the inner ring area, and the outlet areas of the multiple outlet holes 10 in the outer ring area decrease from the inside to the outside, so that 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.

[0078] Preferably, the reduction rate of the outlet area of ​​the 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 both high, and there is no backfire. The honeycomb body is evenly reddened, which can effectively improve thermal efficiency.

[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 in sections from the inside to the outside.

[0080] like Figure 4 As shown, the outlet area of ​​the outlet holes 10 in the outer ring area is smaller than that of the outlet holes 10 in the inner ring area, and the outlet area of ​​the outlet holes 10 in the outer ring area decreases from the inside to the outside. It can also be understood that the outer ring area includes multiple outlet rings, each of which has multiple outlet holes 10, and the outlet areas of the outlet holes 10 on the same outlet ring are the same, but the difference is that the outlet area of ​​the outlet holes 10 decreases once every 2 to 10 outlet rings, so it appears as follows Figure 4 The fire hole area is shown in the state of segmented reduction. This design can not only avoid deflagration, but also increase the transmission rate and make the flame more uniform.

[0081] In a preferred embodiment of the present invention, the area of ​​the air outlet holes located in the inner ring region is equal to the air outlet area of ​​the air outlet holes 10 in the transition zone.

[0082] The success rate or timely rate of the burner's flame transmission is very important. Failure to transmit the flame in time may also cause deflagration due to excessive gas leakage. Figure 2-4 The area of ​​the gas outlet holes 10 in the combustion zone is the same as that of the gas outlet area in the inner ring area, which is beneficial to increase the gas concentration in the combustion zone and facilitates fire transmission.

[0083] In a preferred embodiment of the present invention, there are multiple air outlet holes 10 located in the transition zone, and the air outlet areas of the multiple air outlet holes 10 increase from the inside to the outside.

[0084] like Figure 5 As shown, in order to increase the gas concentration in the combustion zone, the present application increases the area of ​​the multiple air outlet holes 10 in the transition zone from the inside to the outside, so that the air outlet area of ​​the air outlet holes 10 in the transition zone is larger than the air outlet area of ​​the air outlet holes 10 in the inner ring area, which can effectively increase the fire transfer effect of the combustion zone.

[0085] 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 increase from the inside to the outside.

[0086] like Figure 6 As shown, the outlet areas of the multiple outlet holes 10 in the inner ring area increase from the inside to the outside, that is, the outlet volume of a single outlet hole 10 in the inner ring area increases from the inside to the outside. Since the ignition positions of some ignition needles are located at the periphery of the inner ring area, it is mainly necessary that the outlet gas concentration around the ignition needles meets the requirements to avoid flashback caused by uneven outlet gas around the ignition needles in the inner ring area.

[0087] like Figure 2-6 As shown, the outlet area of ​​the air outlet holes 10 in the inner ring region includes two situations, the first one is that the outlet area of ​​the air outlet holes 10 remains unchanged, and the second one is that the outlet area of ​​the air outlet holes 10 increases from the inside to the outside. The outlet area of ​​the air outlet holes 10 in the transition region includes two situations, the first one is that the outlet area of ​​the air outlet holes 10 remains unchanged, and the second one is that the outlet area of ​​the air outlet holes 10 increases from the inside to the outside. The outlet area of ​​the air outlet holes 10 in the outer ring region includes three situations: the first one is that the outlet area of ​​the air outlet holes 10 remains unchanged, the second one is that the outlet area of ​​the air outlet holes 10 decreases from the inside to the outside, and the third one is that the outlet area of ​​the air outlet holes 10 decreases with equal gradients. Different honeycomb bodies can be formed by any combination of the above situations, and can achieve rapid ignition and fire transfer without the problem of deflagration.

[0088] A method for manufacturing a honeycomb body according to an embodiment of the present invention comprises:

[0089] Select a metal strip 1 and determine pressing parameters;

[0090] According to the pressing parameters, a plurality of plane sections 11 and corrugated sections 12 are pressed on the metal strip 1; and then the pressed metal strip 1 is coiled multiple times to form a honeycomb body;

[0091] The gas outlet area at the periphery of the honeycomb body is greater than the gas outlet area at the inner periphery of the honeycomb body.

[0092] Among them, the pressing of the present application can be by rolling, stamping and the like, as long as the plane 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 plane segment 11 and the corrugated segment 12 are connected alternately, for example, the plane segment 11 is located at the initial end of the metal strip 1, and the end of the plane segment 11 is connected to the initial end of the corrugated segment 12, and the initial end of the corrugated segment is connected to the initial end of the next plane segment 11, and the end of the next plane 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 plane segment 11 is set, as long as the plane 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 opened for winding, and the end corresponds to the initial end. The second situation is that the plane segment 11 and the corrugated segment 12 are not connected alternately. For example, the initial end of the metal strip 1 may be a plane segment 11, the second is a corrugated segment 12, the third is still a corrugated segment 12, the fourth is a plane segment 11, and the fifth is still a plane segment 11. This situation is for a coil 100 provided with one plane segment 11 and one corrugated segment 12. Alternatively, the initial end of the metal strip 1 may be a plane segment 11, the second is a corrugated segment 12, the third is still a plane segment 11, the fourth is a corrugated segment 12, the fifth is still a corrugated segment 12, the sixth is a plane segment 11, the seventh is a corrugated segment 12, the eighth is a plane segment 11, the ninth is a plane segment 11, and so on. Each coil 100 has two plane 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 connecting parts of two adjacent winding coils 100 are not the planar segments 11 and the corrugated segments 12 connected alternately, but are two identical shapes, either both are corrugated segments 12 or both are planar segments 11.

[0093] The metal strip 1 is coiled multiple times by the equipment to form a honeycomb body. After coiling, the metal strip 1 becomes a plurality of coiled circles 100. Therefore, the honeycomb body of the present application is composed of a plurality of mutually constrained coiled circles 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 partial bulging upward or moving downward, and is not easy to warp or cause tempering, and has a simple structure and low cost.

[0094] By pressing at least two kinds of waves on the metal strip 1, for example, the cross-sectional area of ​​the wave band near the initial end of the metal strip 1 is smaller than the cross-sectional area of ​​the wave band near the end of the metal strip 1, the area of ​​the air outlet 10 located at the periphery of the honeycomb body can be made smaller than the area of ​​the air outlet 10 located at the inner periphery of the honeycomb body, and the gas concentration at the inner ring or ignition needle can be increased, which is conducive to improving the ignition success rate and the ignition speed can 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 the ignition is successful at this time, it will ignite the surrounding gas and scare the user.

[0095] In the present 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 an air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which not only ensures uniform air outlet, but also plays a role in stabilizing and evenly distributing the airflow and reducing the generation of smoke.

[0096] In addition, the cross-section of the honeycomb body can be in various shapes such as circular, elliptical, rectangular, hexagonal, octagonal, dodecagonal, etc., and the present application does not limit this.

[0097] In a preferred embodiment of the present invention, the pressing parameters include the length of the plane segment 11, the length, wavelength, wave height of the corrugated segment 12, and the shape of the cross section of the corrugated segment 12. The initial position, wavelength, and wave height of different corrugated segments 12 can be determined according to the basic parameters of the prefabricated honeycomb body, and the basic parameters of the honeycomb body include the inner diameter of the honeycomb body and the size and outlet direction of the air outlet 10. For example, the basic parameters of the honeycomb body can be that the inner diameter of the honeycomb body is a, the circumference of the coil 100 is S, and the size of the air outlet. Since the air outlet of the present application is equivalent to each wave of the corrugated segment 12, the size of the air outlet is the wave height of the corrugated segment 12 is d and the wavelength c. In addition, assuming that the thickness of the metal strip 1 is b, and the circumference of the i-th coil 100 is S i ,but:

[0098] S i =π[a+(i-1)(b+d)].

[0099] Among them, i represents the number from the inside to the outside, and the wave height is the height from the inside of the wave crest 121 to the lowest point of the wave trough 122, that is, the distance from the highest point on the inside of a wave crest 121 to the outer periphery of the plane segment 11 located on the inside of the wave.

[0100] Through the above process, the lengths of different coils 100 can be calculated. When the plane segment 11 and the corrugated segment 12 are respectively coiled for one circle to form a coil, the lengths of different coils 100 are the lengths of the plane segment 11 and the corrugated segment 12. If the coil 100 has m plane segments 11 and m corrugated segments 12 at the same time, then the lengths of the plane segment 11 and the corrugated segment 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 different corrugation sections 12 can be determined. Then, the size of each wave in the honeycomb body can be determined according to the size of the air outlet 10.

[0101] 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 then press the metal strip 1 according to these parameters.

[0102] In a preferred embodiment of the present invention, the pressed metal strip 1 also includes a planar section 11, and the planar section 11 and the corrugated section 12 are alternately arranged. The planar section 11 is coiled once to form a first winding circle 100a, and the corrugated section 12 is coiled once to form a second winding circle 100b. The second winding circle 100b is arranged on the outer side of the first winding circle 100a, and the first winding circle 100a is arranged on the outer side of the second winding circle 100b. A honeycomb body is formed by alternately arranging multiple first winding circles 100a and second winding circles 100b.

[0103] In a preferred embodiment of the present invention, one of the first winding coil 100a or the second winding coil 100b is disposed at the innermost side of the honeycomb body.

[0104] Figure 1 As shown, the present application can form a first coiled circle 100a by coiling the plane segment 11 once, and form a second coiled circle 100b by coiling the corrugated segment 12 once, and the outer circle of the first coiled circle 100a is provided with the second coiled circle 100b, and the outer circle of the second coiled circle 100b is provided with the first coiled circle 100a, and so on, and multiple first coiled circles 100a and second coiled circles 100b are alternately arranged to form a honeycomb body. That is, each coiled circle 100 in the honeycomb body is a separate plane segment 11 or corrugated segment 12.

[0105] The innermost side of the honeycomb body may be the first winding circle 100a or the second winding circle 100b. Figure 1The planar segment 11 is shown as the starting end of the metal strip 1, and after winding one circle, 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.

[0106] In addition, the plane section 11 can be wound for multiple turns as required, and the length of the plane section 11 and the number of turns after winding can be set before pressing. The lengths of different plane sections 11 and corrugated sections 12 can be calculated based on the preset inner and outer diameters of the honeycomb body, the thickness of the metal strip 1, the wave height of the corrugated section 12 and other parameters.

[0107] The first winding coils 100a and the second winding coils 100b of the present application are arranged alternately, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first winding coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0108] In a preferred embodiment of the present invention, the pressed metal strip 1 also includes a planar segment 11. The metal strip 1 is coiled to form a coil 100. Each coil 100 has both a planar segment 11 and a corrugated segment 12. The outer side of the corrugated segment 12 is the planar segment 11 of the adjacent coil 100, and the outer side of the planar segment 11 is the corrugated segment 12 of the adjacent coil 100.

[0109] Each coil 100 may be composed of one plane segment 11 and one corrugated segment 12, and each coil 100 may have two plane segments 11 and two corrugated segments 12. Of course, the number of plane 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 limit this.

[0110] When pressing the metal strip 1, it is only necessary to calculate the length of each flat segment 11 and corrugated segment 12 according to the relationship between the inner and outer diameters of the honeycomb body, the number of flat segments 11 and corrugated segments 12 on each winding circle 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 a set program, and then outputs the flat segment 11 and corrugated segment 12 on a metal strip 1.

[0111] In the present application, the outer circle of the plane section 11 on the adjacent coils 100 is the corrugated section 12, and the outer circle of the corrugated section 12 is the plane section 11, that is, the plane section 11 and the corrugated section 12 are arranged alternately from the inner circle to the outer circle, ensuring that the outlet holes are evenly distributed on a gas outlet surface, ensuring uniform gas outlet, stable flame, and less smoke. Here, the outlet hole is the wave band on the corrugated section 12, and each wave band can be used as an outlet hole.

[0112] In a preferred embodiment of the present invention, the plane section 11 is coiled around the outer periphery of the annular body; or the corrugated section 12 is coiled around the outer periphery of the annular body. The plane section 11 can be coiled one or more times to increase the thickness of the inner wall of the honeycomb body and improve the overall compressive strength. The corrugated section 12 can also be coiled around the outer periphery of the annular body. The annular body of the present application can be a steel ring or other annular objects.

[0113] The specific operation is: connect a small plane segment 11 with the annular body, or directly connect a corrugated belt with the annular body, and then wrap it to form a honeycomb body. The annular body can also be used to replace the first plane segment 11, connect the corrugated segment 12 to the outer periphery of the steel ring, and then wind the plane segment 11 connected to the corrugated segment 12 around the outer periphery of the corrugated segment 12 to finally form a honeycomb body.
