[0037] 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.

[0038] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" 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.

[0039] A honeycomb body according to an embodiment of the present invention comprises: a honeycomb body connected to the top of a furnace head, the furnace head having at least two gas supply channels, the honeycomb body having at least two annular gas outlet areas corresponding to the gas supply channels, each annular gas outlet area being provided with a plurality of gas outlet channels;

[0040] Wherein, the inclination angle of the air outlet channel located in any of the air outlet areas is greater than or equal to the inclination angle of the air outlet channel of the adjacent outer air outlet area.

[0041] 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 past 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 from the inside to the outside on the burner. In order to correspond to, in addition, a partition can be installed between the honeycomb body and the flame distribution plate, and the partition divides the flame distribution plate into a plurality of sub-cavities to correspond to the air supply channels on the burner. The partition part can be an annular partition, a cylinder, etc. For the convenience of illustration, the present application takes a double ring as an example, and sets the partition part as follows Figure 2 The dividing line shown by P1 is such that the honeycomb body forms inner and outer ring regions.

[0042] The outlet direction of the outlet channel is inclined to the plane where the top surface of the honeycomb body is located, so the angle between the outlet direction of the outlet channel and the plane where the top surface of the honeycomb body is located is called the inclination angle of the outlet channel. Due to the different inclination angles of the outlet channel, the resistance to the gas will be different, and the outlet speed of the gas at the fire hole will also be different. Among them, the smaller the inclination angle, the greater the outlet concentration / speed. In any two adjacent annular outlet areas, the inclination angle of the outlet channel of the annular outlet area located on the outside is greater than or equal to the inclination angle of the outlet channel of the annular outlet area located on the inside, which can increase the outlet concentration / speed of the honeycomb body and gradually simplify it outward, making it easier to ignite and transfer fire, and avoiding 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 it is suddenly ignited successfully at this time, it will ignite the surrounding gas and scare the user.

[0043] In a preferred embodiment of the present invention, a metal strip 1 is provided, the metal strip 1 includes 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, wherein the planar segments 11 and the corrugated segments 12 cooperate to form an air outlet channel.

[0044] 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 stamping. The flat section 11 and the corrugated section 12 are mutually arranged to form an air outlet channel, wherein each wave section on the corrugated section 12 can be used as an air outlet hole in the air outlet channel.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc.

[0050] 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.

[0051] The first winding coils 100a and the second winding coils 100b are arranged alternately.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 .

[0058] 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.

[0059] As long as the outer circle of the plane section 11 on the adjacent winding ring 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, it is ensured that the outlet holes are evenly distributed on a gas outlet surface, and the gas outlet is uniform. Here, the gas outlet hole is the wave segment on the corrugated section 12, and each wave can be used as a gas outlet hole, ensuring uniform gas outlet, stable flame, and less smoke.

[0060] 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 2 .

[0061] 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.

[0062] 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 .

[0063] like Figure 1 As shown, the corrugation segment 12 includes a plurality of crests 121 and a plurality of troughs 122, wherein 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.

[0064] In such Figure 1 In the honeycomb body shown, part of the transition section 101 is connected between the first wave crest and the Nth wave crest on the same corrugated section 12, and the remaining part of the transition section 101 is connected between the first wave trough and the Nth wave 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 wave crest and the Nth wave crest, and the first wave trough and the Nth wave trough. The quadrilateral can be used to coil the corrugated section 12 into a whole, and the corrugated section 12 and the plane section 11 can be tightly connected to form a whole, thereby avoiding the problem of warping of the honeycomb body.

[0065] exist Figure 1In the honeycomb body shown, a transition section 101 is provided between two adjacent winding circles 100. Because the inner side of the planar section 11 after winding is in close contact with the outer periphery of the corrugated section 12 located on the inner circle, the first winding circle 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 wound toward the outer circle, it is necessary to wind from the trough 122 of the corrugated section 12 located at the initial end to its crest 121 and continue to wind against the outer periphery of the corrugated section 12 to form the second winding circle 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, and this cycle will be repeated to form a tightly connected honeycomb body to avoid the problem of honeycomb body warping caused by local bulging upward or downward movement.

[0066] In a preferred embodiment of the present invention, the cross section of the corrugated section 12 is an arc wave, the wavelength of the arc wave is 0.2 mm to 3 mm, and the wave height of the triangular wave is 0.1 mm to 2 mm.

[0067] like Figure 1 As shown, whether the corrugated section 12 forms a coil 100 alone or the corrugated section 12 is a regular shape band, each wave is triangular in shape, 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. The cross section of the corrugated section 12 is a triangular wave, a rectangular wave, a trapezoidal wave, a hexagonal wave, etc.

[0068] 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.

[0069] 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 .

[0070] like Figure 1As shown, the gas outlet channel of the corrugated section 12 is inclined with respect to the overall extension direction of the metal strip 1, that is, the gas outlet channel of the corrugated section 12 is inclined. Compared with the conventional vertical gas outlet channel, it has a longer channel, which can increase the flow time of the gas or mixed gas and improve the heat exchange effect of the gas or mixed gas. At the same time, because the corrugated section 12 is inclined, the channel cross-section area of ​​the corrugated section 12 is larger, which can improve the heat radiation effect.

[0071] In a preferred embodiment of the present invention, the inclination angle of the air outlet channel is α, wherein 5°≤α≤45°.

[0072] like Figure 1 and 3 As shown, the inclination angle of the gas outlet channel in the present application is the angle between the inclination direction of the corrugated section 12 and the overall extension direction of the metal strip 1, and the inclination direction of the gas outlet channel is set to be inclined from bottom to top. When 5°≤α≤45°, the gas is subject to less resistance, which can increase heat exchange and improve the heat radiation effect.

[0073] In a preferred embodiment of the present invention, there are two annular air outlet areas, namely an inner ring air outlet area and an outer ring air outlet area located outside the inner ring air outlet area, and the inclination angle of the air outlet channel located inside the outer ring air outlet area is equal to the inclination angle of the air outlet channel located in the inner ring air outlet area.

[0074] Among them, this application is aimed at the double-ring burner, and the honeycomb body is divided into an inner ring gas outlet area and an outer ring gas outlet area, which is more in line with the requirements of production and installation. Figure 2 As shown, line P1 is the dividing line between the inner ring area and the outer ring air outlet area, and the area between line P1 and line P2 is a transition area, that is, line P2 is the dividing line between the transition area and the outer ring area. Figure 2 It is not difficult to see that in the two adjacent annular areas, the inclination angle of the air outlet channel in the transition area is equal to the air outlet channel in the inner ring area, which facilitates the smooth fire transmission of the inner air outlet channel and improves the fire transmission efficiency. The inclination angle of the air outlet channel outside the outer ring area is greater than or equal to the inclination angle of the air outlet channel in the inner ring area, which can avoid the deflagration caused by the excessive air outlet speed of the outer ring of the honeycomb body and improve the user experience.

[0075] In a preferred embodiment of the present invention, the inclination angle of the outlet channel located in the outer ring outlet area is α1, 30°≤α1≤45°;

[0076] The inclination angle of the air outlet channel located in the inner ring air outlet area is α2, 5°≤α2≤30°;

[0077] Among them, α2≤α1.

[0078] like Figure 2As shown, the different inclination angles of the gas outlet channel will cause different resistances to the gas passing through the gas outlet channel, and the gas outlet velocity at the fire hole will also be different. When the inclination angle α2 of the gas outlet channel 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 conducive to ignition.

[0079] The inclination angle of the gas outlet channel in the outer ring area is greater than or equal to the inclination angle of the gas outlet channel in the inner ring area, so α2≤α1. This design 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.

[0080] A method for manufacturing a honeycomb body according to an embodiment of the present invention comprises:

[0081] Selecting a metal thin strip 1 and determining basic parameters of a prefabricated honeycomb body;

[0082] Calculate the lengths of the flat section 11 and the corrugated section 12 according to the basic parameters of the honeycomb body;

[0083] According to the obtained lengths of the plane segment 11 and the corrugated segment 12, multiple plane segments 11 and multiple corrugated segments 12 are pressed on the metal strip 1, and the corrugated segment 12 is a corrugation inclined to the overall extension direction of the metal strip 1; then the metal strip 1 is coiled multiple times to form a honeycomb body.

[0084] Among them, the pressing of the present application can be by rolling, stamping and the like, as long as the plane 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 overall extension direction of the metal strip 1, so that the gas outlet channel is inclined, and by controlling the inclination angle of the gas outlet channel on different corrugated sections 12, the inclination angle of the gas outlet channel in the outer annular gas outlet area in the two adjacent annular gas outlet areas can be greater than or equal to the inclination angle of the gas outlet channel in the inner annular gas outlet area. By increasing the gas outlet concentration / speed around the honeycomb body, it is easier to ignite and transfer fire, and temporary ignition due to insufficient concentration in the inner ring can be avoided. The outer ring nozzle is larger, releasing 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.

[0085] The specific winding structure of the honeycomb body is as follows: In the first case, the plane segment 11 and the corrugated segment 12 are connected alternately. For example, the initial end of the metal strip 1 is the plane segment 11, and the end of the plane 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 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.

[0086] 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.

[0087] 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 air outlet 10 and the air outlet direction, and 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 according to the basic parameters of the honeycomb body and the thickness of the metal strip 1.

[0088] Among them, the basic parameters of the honeycomb body can be the inner diameter of the honeycomb body a, the circumference of the coil 100 is 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:

[0089] S i =π[a+(i-1)(b+d)].

[0090] 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.

[0091] 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 corrugated segments 12 can be determined. Then, the size of each wave in the honeycomb can be determined according to the size of the outlet hole 10. According to the outlet direction of the outlet hole in the honeycomb, the inclination angle of the corrugated segment 12 can be calculated. According to the size of the outlet hole 10, the size of each wave in the honeycomb can be determined.

[0092] 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 segment 12 and the inclination angle of the corrugated segment 12, and then press the metal strip 1 according to these parameters.

[0093] 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.

[0094] 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 the present application does not limit this.

[0095] In a preferred embodiment of the present invention, the planar section 11 is coiled once to form a first coiled coil 100a, and the corrugated section 12 is coiled once to form a second coiled coil 100b. The second coiled coil 100b is arranged outside the first coiled coil 100a, and the first coiled coil 100a is arranged outside the second coiled coil 100b. A honeycomb body is formed by alternately arranging a plurality of first coiled coils 100a and second coiled coils 100b.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] In a preferred embodiment of the present invention, the lengths of the planar section 11 and the corrugated section 12 are adjusted so that each winding coil 100 has both the planar section 11 and the corrugated section 12, and the outer side of the corrugated section 12 is the planar section 11 of the adjacent winding coil 100, and the outer side of the planar section 11 is the corrugated section 12 of the adjacent winding coil 100.

[0102] Each coil 100 may have one plane segment 11 and one corrugated segment 12, or 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.

[0103] 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.

[0104] In the present application, the outer circle of the plane section 11 on the adjacent coiled ring 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. Here, the outlet hole is the wave segment on the corrugated section 12, and each wave can be used as an outlet hole, ensuring uniform gas outlet, stable flame, and less smoke.

[0105] 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.

[0106] 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.
