Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of gas devices, and in particular to a combustion channel structure and a manufacturing method thereof, and a burner. Background Art
[0002] In the exemplary technology, the burner generally includes a gas channel and an air channel. In order to ensure a good mixture of gas and air, a mixing chamber or a mixed combustion channel is usually provided for a good mixing of gas and air, thereby improving the combustion efficiency of the burner. In addition, in order to ensure the mixing efficiency, the inner wall of the mixing chamber or the mixed combustion channel has certain processing requirements. When it is necessary to fully mix the fluids in the combustion channel and the mixing channel, a large connecting area between the mixing chamber (or the mixed combustion channel) and the gas channel or the air channel is ensured. This will make the processing of the mixing chamber (or the mixed combustion channel) more difficult. The combustion channel or combustion chamber itself is formed by the company after many years of experiments. Generally, the optimal combustion channel or combustion chamber will not change frequently after it is determined. When it needs to be applied to different burners, the original combustion channel structure size may not meet the requirements of the new burner, and the mold needs to be reprocessed, thereby increasing the mold cost.

[0045] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0047] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0048] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0049] The present invention provides a combustion channel structure 100 for a burner, wherein the burner includes a gas outlet.
[0050] Reference Figures 1 to 6 The combustion channel structure 100 proposed in the technical solution of the present invention includes:
[0051] an isolating member 10 , wherein the isolating member 10 is formed with a first through hole 11 ; and
[0052] The connecting piece 20 is stacked with the isolation piece 10 and together encloses the combustion channel 40. The connecting piece 20 is formed with a notch 21, and the notch 21 is connected to the first through hole 11 and connected to the combustion channel 40. The first through hole 11 or the notch 21 is connected to the gas outlet.
[0053] The technical solution of the present invention is to provide an isolation member 10 having a first through hole 11 and a connecting member 20 having a notch 21, and to stack the isolation member 10 and the connecting member 20 to enclose a combustion channel 40, and further connect the notch 21 with the first through hole 11 and the combustion channel 40. When the gas structure needs to be used, the first through hole 11 or the notch 21 is connected to the gas outlet, which can be a gas outlet after the gas and air are mixed, so that the mixed gas can be fully mixed in the combustion channel; or the gas outlet is an air outlet, or the gas outlet is a gas outlet. Specifically, the first through hole 11 can be connected to the air outlet of the gas channel, and the air outlet of the air channel can be connected to the combustion channel 40; or the notch 21 can be connected to the air outlet of the air channel, and the gas outlet of the gas channel can be connected to the combustion channel 40, so that the gas and air can flow through the first through hole 11 or the notch 21 and enter the combustion channel 40 for mixing. Since the combustion channel 40 is formed by a split structure, when the combustion channel 40 needs to be adjusted, the isolation piece 10 and the connecting piece 20 can be re-adjusted and assembled, which greatly improves the versatility of the combustion channel 40. In addition, the split parts are generally smaller than the overall combustion channel structure 100, which reduces the size and shape of the mold and reduces the mold cost.
[0054] In this embodiment, the spacer 10 and the connecting piece 20 can be made of metal to improve their heat resistance and make the combustion channel structure 100 more stable. In some embodiments, the stacked spacer 10 and the connecting piece 20 can be connected together in sequence by spot welding or fixed together in sequence by stamping.
[0055] In some embodiments of the present invention, the aperture d of the first through hole 11 is in the range of 0.1 mm ≤ d ≤ 10 mm. When the aperture is less than 0.1 mm, the gas or air flow rate will be small, and more through holes will be required to ensure sufficient flow of the gas or air. When the aperture is greater than 10 mm, the hollow area of the separator 10 will be increased, which will reduce the strength of the separator 10 and will not be conducive to ensuring the structural stability of the combustion channel 40. When the aperture d is in the range of 0.1 mm ≤ d ≤ 10 mm, it is convenient to ensure sufficient gas flow rate on the one hand, and on the other hand, it can also ensure the structural strength of the separator 10. It is understandable that the aperture d can also be 0.2 mm, 0.5 mm, 0.7 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc., which can ensure sufficient gas flow rate on the one hand, and ensure the structural strength of the separator 10 on the other hand. The first through hole 11 can be configured to gradually decrease in size from the air inlet side to the air outlet side. This configuration can increase the flow rate of the fluid during the outlet, ensure the contact efficiency between the air and the gas when the gas outlet is an air outlet, or when the gas outlet is a gas outlet, and improve the combustion efficiency of the gas. In addition, when the aperture of the first through hole 11 is not within the range of 1mm≤d≤10mm, the mixed gas flowing out of the first through hole 11 is likely to have an excessively high pressure, and then directly spray into the first through hole 11 on the other side, greatly reducing the outlet efficiency of the first through hole 11, or the gas pressure flowing out of the first through hole 11 is insufficient, and the space of the combustion channel 40 cannot be fully utilized. When the aperture of the first through hole 11 is within the range of 1mm≤d≤10mm, the mixed gas can be evenly distributed in the combustion channel 40, improving the combustion efficiency. It is understandable that the aperture d can also be set to 0.2 mm, 0.5 mm, 0.7 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, etc., which can evenly distribute the mixed gas in the combustion channel 40 and improve combustion efficiency.
[0056] In some embodiments of the present invention, the opening of the notch 21 can be consistent with the aperture size of the first through hole 11, so as to facilitate the fluid flowing out of the first through hole 11 to flow into the combustion channel 40 from the notch 21. The notch 21 can also be set in the shape of a through hole, and further by setting a connecting groove so that the hole wall is penetrated, when it is needed, the through hole is connected to the first through hole 11, or directly connected to the air channel or the gas channel. The gas outlet, and the connecting groove are connected to the combustion channel 40, and the combustion channel 40 can be formed by the isolation member 10 and the connecting member 20, and it is convenient to use. Furthermore, the connecting groove can be connected to the through hole from the inside of the connecting member 20, or connected to the through hole on the surface of the connecting member 20, as long as it is convenient to connect the through hole to the combustion channel 40.
[0057] It is understood that the air and gas channels are specifically connected to the first through-hole 11 or the notch 21, which is not a specific requirement and can be determined based on the stacking configuration used by the user. At least one of the air and gas flows from the first through-hole 11 or the notch 21 into the combustion channel 40, while the other directly connects to the combustion channel 40, achieving mixing within the combustion channel 40.
[0058] In some embodiments of the present invention, the number of the isolating members 10 and the number of the connecting members 20 are both multiple, and the isolating members 10 and the connecting members 20 are alternately stacked so that the first through hole 11 and the notch 21 are alternately connected. In one embodiment, the isolating members 10 and the connecting members 20 can both be plate-shaped. Such a configuration can shorten the length that the first through hole 11 and the notch 21 need to penetrate, thereby improving processing efficiency. In addition, by stacking multiple isolating members 10, the length of the combustion channel 40 can be flexibly adjusted, greatly improving the versatility of the combustion channel 40. The thickness of the isolating members 10 and the connecting members 20 can also be set according to actual conditions, and isolating members 10 and connecting members 20 of different thicknesses can be stacked to further improve the adaptability of the combustion channel structure 100. Specifically, the thickness of the isolating member 10 and the connecting member 20 can be any value between 0.5 mm and 100 mm (specifically, 1 mm, 2 mm, 5 mm, 10 mm, 20 mm, 50 mm, 70 mm, 90 mm, etc.), as long as the isolating member 10 can have a certain strength and it is convenient to form the first through hole 11. Similarly, the thickness of the connecting member 20 can be any value between 0.5 mm and 100 mm (specifically, 1 mm, 2 mm, 5 mm, 10 mm, 20 mm, 50 mm, 70 mm, 90 mm, etc.), as long as it is convenient to form the notch 21. And by alternating the arrangement, the distribution of the notch 21 can be uniform, so that the fluid entering the first through hole 11 can be easily introduced into the combustion channel 40, thereby improving the combustion efficiency. It should be noted that the alternation in this embodiment does not only mean the form of stacking one insulating piece 10 on one connecting piece 20 and then stacking another insulating piece 10, but also includes the form of stacking multiple connecting pieces 20 on one insulating piece 10, stacking multiple insulating pieces 10 on one connecting piece 20, and stacking m connecting pieces 20 on n insulating pieces 10 (n and m can be equal or unequal values), as long as the distribution of the gaps 21 is convenient.
[0059] Reference Figure 2 、 Figure 11In this embodiment, multiple isolation members 10 and connecting members 20 are alternately stacked, so that multiple first through holes 11 and multiple notches 21 together form an independent combustion space 50 (it can be understood that at least one through hole and at least one first notch can also form an independent combustion space 50). Furthermore, due to the provision of multiple notches 21, the mixed gas in the combustion space 50 can be ignited at the multiple notches 21 to form multiple ignition points, thereby greatly improving the efficiency of gas combustion.
[0060] Reference Figure 1 、 Figure 2 and Figure 5 In some embodiments of the present invention, the combustion channel structure 100 further includes a base 30, wherein the base 30 is formed with a second through hole 31, and the second through hole 31 is connected to the first through hole 11 and / or the notch 21, and is connected to the gas outlet of the gas channel;
[0061] The base 30 is also provided with at least one mounting column 32, the isolating member 10 is provided with a first connecting hole 12, and the connecting member 20 is provided with a second connecting hole 22. The mounting column 32 passes through the first connecting hole 12 and the second connecting hole 22 to fix the base 30, the isolating member 10 and the connecting member 20 together.
[0062] In this embodiment, the thickness of the base 30 is slightly greater than the sum of the thicknesses of a single isolating member 10 and a single connecting member 20, thereby ensuring initial support for the isolating member 10 and the connecting member 20. The second through hole 31 is used to guide the fluid flowing out of the gas channel outlet or the air channel outlet. When the connecting member 20 is first placed on the base 30, the fluid is guided to the notch 21. Part of the fluid entering the notch 21 enters the combustion channel 40, and the other part enters the first through hole 11. When the isolating member 10 is first placed on the base 30, the fluid is guided to the first through hole 11, and then the fluid flows from the first through hole 11 into the notch 21. Part of the fluid entering the notch 21 enters the combustion channel 40, and the other part enters the first through hole 11 of the next isolating member 10. In this embodiment, by providing the first connecting hole 12, the second connecting hole 22, and the mounting post 32, the isolating member 10 and the connecting member 20 can be connected in series on the mounting post 32. In one embodiment, the end of the mounting post 32 away from the base 30 can be provided with an external thread, and the isolating member 10 and the connecting member 20 can be fixed by further providing a nut that is sleeved on the mounting post 32. Alternatively, the mounting post 32 is provided in a tubular shape, and the isolating member 10 and the connecting member 20 sleeved thereon are interference-connected with the mounting post 32 to achieve the fixation of the isolating member 10 and the connecting member 20. In one embodiment, the connecting member 20 or the isolating member 10 located at the end of the mounting post 32 away from the base 30 can be welded to the mounting post 32. With such a configuration, the other isolating members 10 and the connecting member 20 sleeved on the mounting post 32 can be limited by the end connecting member 20 or the isolating member 10, thereby improving production efficiency.
[0063] Reference Figure 2 and Figure 5 In some embodiments of the present invention, there are multiple mounting posts 32, and the multiple mounting posts 32 are spaced apart on the base 30. The isolating member 10 is provided with multiple first connection holes 12, and the connecting member 20 is provided with multiple second connection holes 22. One mounting post 32 passes through one first connection hole 12 and one second connection hole 22. The base 30, the isolating member 10, and the connecting member 20 together enclose the combustion channel 40. By providing multiple mounting posts 32, multiple positions of the isolating member 10 and the connecting member 20 are connected and fixed in series, thereby improving the fixing effect of the isolating member 10 and the connecting member 20. When there are multiple mounting posts 32, the multiple mounting posts 32 are spaced apart around the base 30. Alternatively, the first connection holes 12 and the second connection holes 22 may not be provided, and the two sides of the isolating member 10 and the connecting member 20 may be directly clamped between the mounting posts 32, thereby achieving the fixing of the isolating member 10 and the connecting member 20.
[0064] Reference Figure 6In some embodiments of the present invention, the isolating member 10 is provided with a first plug-in column 13 and a first plug-in hole 14, and the connecting member 20 is provided with a second plug-in column 23 and a second plug-in hole 24. The number of the isolating members 10 and the number of the connecting members 20 are both plural. When the isolating members 10 and the connecting members 20 are alternately stacked, the first plug-in column 13 of one isolating member 10 is plugged into the second plug-in hole 24 of one connecting member 20, and the second plug-in column 23 of the connecting member 20 is plugged into the first plug-in hole 14 of another isolating member 10. With such an arrangement, adjacent isolating members 10 and connecting members 20 can be fixed to each other, thereby ensuring the connection effect between the isolating members 10 and the connecting members 20. Preferably, the outline dimensions of the first plug-in column 13, the second plug-in column 23, the first plug-in hole 14 and the second plug-in hole 24 are similar, thereby improving the installation efficiency of the isolating members 10 and the connecting members 20. Furthermore, when the plug-in post is plugged into the plug-in hole, it can be in interference fit with the plug-in hole, thereby improving the fixing effect.
[0065] Reference Figures 1 to 5 In some embodiments of the present invention, each of the isolation members 10 has a plurality of first through holes 11, and each of the connecting members 20 has a plurality of notches 21, with each first through hole 11 communicating with a notch 21. By providing a plurality of first through holes 11 and a plurality of notches 21, fluid flowing out of the gas or air passage can be directed into the first through holes 11 at multiple locations. The multiple notches 21 then direct the fluid into the combustion channel 40, improving the efficiency of the fluid entering the combustion channel 40 and, in turn, improving combustion efficiency.
[0066] Reference Figures 1 to 6 It can be understood that when each isolating member 10 has a plurality of first through holes 11 and each connecting member 20 has a notch 21, by alternately stacking a plurality of isolating members 10 and connecting members 20, the plurality of first through holes 11 and the plurality of notches 21 arranged in the same column together form an independent combustion space 50 (it can be understood that at least one through hole 11 and at least one notch 21 can also form an independent combustion space 50), thereby obtaining a plurality of independent combustion spaces 50 located in different columns. Furthermore, since each combustion space 50 is provided with a plurality of notches 21, the mixed gas in the combustion space 50 can be ignited at the plurality of notches 21 to form a plurality of ignition points, thereby greatly improving the efficiency of gas combustion.
[0067] Reference Figures 1 to 6In some embodiments of the present invention, the isolating member 10, the connecting member 20 and the base 30 are all arranged in an annular shape, a plurality of the first through holes 11 are evenly distributed on the isolating member 10, a plurality of the notches 21 are evenly distributed on the connecting member 20, and the combustion channel 40 is arranged in the middle of the isolating member 10, the connecting member 20 and the base 30. Such an arrangement facilitates the concentration of the mixed air and gas, so that the flame of the combustion channel structure 100 is concentrated. In one embodiment, the isolating member 10, the connecting member 20 and the base are all arranged in an annular shape. Since the circle has a larger area under the same circumference, the diameter of the combustion channel 40 is larger, and the air and gas have a larger mixing space, thereby improving the mixing efficiency.
[0068] Reference Figure 2 、 Figure 11 It can be understood that the number of the second through holes 31 of the sink 33 is multiple, and each second through hole 31 is set corresponding to a combustion space 50, which ensures that each independent combustion space 50 is adequately supplied with air and improves combustion efficiency.
[0069] In one embodiment, the mounting post 32 is provided on the upper surface of the base 30. The lower surface of the base 30 is provided with a recessed platform 33. One end of the second through hole 31 is provided through the recessed platform 33. This arrangement increases the structural area of the combustion channel structure 100 and the mounting surface during installation. The recessed platform is provided to prevent positioning errors, thereby improving installation efficiency and stability.
[0070] Reference Figure 12 The present invention also proposes a method for manufacturing a combustion channel structure 100, wherein the method for manufacturing the combustion channel structure 100 is used to manufacture the combustion channel structure 100, referring to Figure 8 The manufacturing method of the combustion channel structure 100 includes the following steps:
[0071] Step S10: Align and stack the spacer 10 and the connecting member 20 so that the first through hole 11 is connected to the notch 21. In this embodiment, since the first through hole 11 and the notch 21 need to guide the fluid in the air or gas channel to the combustion channel 40, connecting them improves the guidance efficiency. The alignment can be performed by setting alignment marks or using an alignment jig, as long as a good alignment effect is achieved.
[0072] Step S20: Use a positioning fixture to define the relative positions of the isolator 10 and the connecting member 20. In this embodiment, defining the relative positions of the isolator 10 and the connecting member 20 improves the processing quality of the two during subsequent processing. Specifically, the positioning fixture can be a positioning clamp or a positioning pliers, as long as it can achieve a good positioning effect.
[0073] Step S30: Securely connect the isolating member 10 and the connecting member 20 and remove the positioning fixture. In this embodiment, the isolating member 10 and the connecting member 20 can be fixed by stamping or welding. If the isolating member 10 and the connecting member 20 need to be adjusted, they can be separated by desoldering or other methods to improve the adaptability of the combustion channel 40.
[0074] In this embodiment, an isolation member 10 having a first through hole 11 and a connecting member 20 having a notch 21 are provided, and the isolation member 10 and the connecting member 20 are stacked and arranged to enclose a combustion channel 40, and the notch 21 is further connected to the first through hole 11 and connected to the combustion channel 40. When the gas structure needs to be used, the first through hole 11 or the notch 21 is connected to the gas outlet, which can be a gas outlet after the gas and air are mixed. In this way, the mixed gas can be fully mixed in the combustion channel; or the gas outlet is an air outlet, or the gas outlet is a gas outlet. Specifically, the first through hole 11 can be connected to the air outlet of the gas channel, and the air outlet of the air channel can be connected to the combustion channel 40; or the notch 21 can be connected to the air outlet of the air channel, and the gas outlet of the gas channel can be connected to the combustion channel 40, so that the gas and air can flow through the first through hole 11 or the notch 21 and enter the combustion channel 40 for mixing. Since the combustion channel 40 is formed by a split structure, when the combustion channel 40 needs to be adjusted, the isolation piece 10 and the connecting piece 20 can be re-adjusted and assembled, which greatly improves the versatility of the combustion channel 40. In addition, the split parts are generally smaller than the overall combustion channel structure 100, which reduces the size and shape of the mold and reduces the mold cost.
[0075] In some embodiments of the present invention, step S10 includes:
[0076] In step S11, a base 30 is provided, and the isolating member 10 is sleeved on the mounting column 32 of the base 30 through the first connecting hole 12, and the second through hole 31 is connected to the first through hole 11. In this embodiment, the isolating member 10 is installed on the base 30 by sleeve connection, and the second through hole 31 is aligned and connected to the first through hole 11 to improve ventilation efficiency.
[0077] In step S12, the connecting piece 20 is then sleeved on the mounting column 32 of the base 30 through the second connecting hole 22 to complete the alignment of the isolation piece 10 and the connecting piece 20. In this embodiment, the installation of the connecting piece 20 and the base 30 is achieved by sleeve connection, and the notch 21 is aligned and connected with the first through hole 11 to improve the ventilation efficiency.
[0078] In step S13, the plurality of spacers 10 and the plurality of connecting members 20 are sequentially sleeved together to alternately connect the first through-holes 11 with the notches 21. This alternating arrangement of the plurality of spacers 10 and connecting members 20 allows for a uniform distribution of the notches 21 and facilitates the formation of combustion channels 40 of varying sizes. This facilitates the flow of fluid entering the first through-holes 11 into the combustion channels 40, thereby improving combustion efficiency.
[0079] In this embodiment, the isolation member 10 and the connecting member 20 are installed by setting a base 30 so that the isolation member 10 and the connecting member 20 are sleeved on the installation column 32, thereby improving the installation efficiency of the isolation member 10 and the connecting member 20 and the stability of the combustion channel structure 100.
[0080] In some embodiments of the present invention, step S30 includes:
[0081] The isolating pieces 10 and the connecting pieces 20 are fixed by welding or stamping in sequence; in this way, the adjacent isolating pieces 10 and the connecting pieces 20 can be fixed together, thereby improving the fixing effect of the isolating pieces 10 and the connecting pieces 20.
[0082] Alternatively, the connecting piece 20 or the isolating piece 10 located at the end of the mounting column 32 away from the base 30 is welded and fixed to the mounting column 32. With such an arrangement, the connecting piece 20 or the isolating piece 10 at the end can limit the other isolating pieces 10 and the connecting piece 20 that are sleeved on the mounting column 32, thereby improving production efficiency. It should be noted that since the isolating piece 10 and the connecting piece 20 in the middle are not fixed to other components, it is necessary to press the isolating piece 10 and the connecting piece 20 in the middle tightly, and then weld the connecting piece 20 or the isolating piece 10 located at the end of the mounting column 32 away from the base 30 to the mounting column 32, thereby improving the molding effect of the combustion channel structure 100.
[0083] Refer to 7 to Figure 11 The present invention further provides a burner 200, comprising a combustion channel structure 100, wherein the combustion channel structure 100 comprises an isolating member 10, wherein the isolating member 10 is formed with a first through hole 11; and a connecting member 20, wherein the connecting member 20 and the isolating member 10 are stacked and arranged to enclose the combustion channel 40 together, wherein the connecting member 20 is formed with a notch 21, wherein the notch 21 is connected to the first through hole 11 and is connected to the combustion channel 40, and the first through hole 11 or the notch 21 is connected to the gas outlet;
[0084] Alternatively, the burner 200 includes a combustion channel structure 100 manufactured using the manufacturing method of the combustion channel structure 100, and the manufacturing method of the combustion channel structure 100 includes the following steps: Step S10: aligning and stacking the isolation member 10 and the connecting member 20 so that the first through hole 11 is connected to the notch 21; Step S20: defining the relative position of the isolation member 10 and the connecting member 20 by a positioning fixture; Step S30: fixing the isolation member 10 and the connecting member 20 and removing the positioning fixture. Since the burner 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0085] Reference Figures 7 to 11 In some embodiments of the present invention, the combustion channel structure 100 further includes an end cover 201 and a combustion seat 202, wherein the combustion seat 202 includes an installation cavity 2021, and the combustion seat 202 is further provided with an air outlet 2022 connected to the installation cavity 2021, and the air outlet 2022 can output gas, air, or a mixture of gas and air (one end of the air outlet 2022 can be connected to the premixing chamber 204 of the burner 200, and the premixing chamber 204 is used to mix air and gas). When the combustion channel structure 100 is placed in the installation cavity 2021, the gas flowing out of the air outlet 2022 can flow into the combustion space of the combustion channel structure 100, and then flow into the combustion channel 40 from the notch 21 for combustion. In addition, the end cover 201 is arranged at the end of the combustion channel structure 100 away from the air outlet 2022. On the one hand, it can block the combustion space of the combustion channel structure 100 so that the air outlet part of the combustion space has only a gap 21, ensuring sufficient combustion gas at the ignition point, and thus ensuring the combustion effect in the combustion channel 40; on the other hand, it can fix the combustion channel structure 100 to ensure that the relative position of the combustion channel structure 100 and the combustion seat 202 is fixed.
[0086] Reference Figure 2 、 Figure 11 In one embodiment, the base of the combustion channel structure 100 is provided with a surrounding sinker, which connects all the second through holes to the side away from the connecting piece 20 and / or the isolation piece 10, and forms a buffer space 203 between the sinker and the installation cavity 2021. With such a configuration, when the combustion channel structure 100 is placed in the installation cavity 2021, the mixed gas flowing out of the outlet hole 2022 can rebalance the premixed pressure in the buffer space 203 formed by the sinker and the installation cavity 2021, forming a stable mixed gas, thereby balancing the pressure of the mixed gas entering the second through hole and improving the combustion efficiency.
