[0003] The technical problem to be solved by this application is to provide a burner that can ensure the correct installation direction of the ignition needle.

[0004] The technical solution of this application to solve the above-mentioned technical problems is as follows: A burner includes a first burner unit, an ignition needle, and a fixing bracket; the first burner unit has a plurality of first flame holes; the ignition needle has a bent ignition tip, the ignition tip extending to a region near the opening of the first flame hole; the ignition needle is fixed to the fixing bracket for mounting on the burner via the fixing bracket; wherein, the ignition needle is provided with a foolproof part, the fixing bracket is provided with a foolproof mating part, the foolproof part is used to match the foolproof mating part to achieve circumferential positioning of the ignition needle itself, so that the bending direction of the ignition tip faces the opening of the first flame hole.

[0005] The beneficial effect of this application is that, through the cooperation between the anti-mistake part on the ignition needle and the anti-mistake mating part on the fixed bracket, the installation and fixation between the ignition needle and the fixed bracket can only be correctly achieved when the ignition needle is placed at a specific preset angle relative to the fixed bracket, thereby realizing the anti-mistake installation of the ignition needle and improving the ignition success rate.

[0006] Based on the above technical solution, the following improvements can be made to this application.

[0007] Furthermore, the fixed bracket includes a fixed plate and a connecting element disposed on the fixed plate, the ignition needle is fixed to the fixed plate through the connecting element, and the foolproof mating part is disposed on the fixed plate.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the ignition needle is fixed to the fixing plate by the connecting element, which facilitates the installation and disassembly between the ignition needle and the fixing plate, thereby facilitating the maintenance or replacement of the ignition needle. When installing the ignition needle, the foolproof installation of the ignition needle is achieved through the foolproof cooperation between the ignition needle and the fixing plate.

[0009] Furthermore, the error-proofing part includes one or a combination of two of the first error-proofing part and the second error-proofing part. Correspondingly, the error-proofing mating part includes one or a combination of two of the first error-proofing mating part that can mate with the first error-proofing part and the second error-proofing mating part that can mate with the second error-proofing part.

[0010] The advantage of adopting the above-mentioned further solution is that the error prevention part can adopt one error prevention component or multiple error prevention components. Correspondingly, the error prevention mating part can adopt one error prevention mating part or multiple error prevention mating parts. Therefore, the structure of the error prevention part and the error prevention mating part can have a variety of choices.

[0011] Furthermore, the first anti-foolproof part includes an anti-foolproof surface, the first anti-foolproof mating part includes an anti-foolproof mating surface, and the anti-foolproof surface and the anti-foolproof mating surface are mated by a form-surface fit.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the anti-mistake surface and the anti-mistake mating surface adopt a shape-surface fit. When the ignition needle is installed, as long as the anti-mistake surface and the anti-mistake mating surface are fully fitted, the anti-mistake fit between the ignition needle and the fixing plate can be achieved. Moreover, the anti-mistake structure is a surface-to-surface fit, which is convenient for processing and not easy to be damaged.

[0013] Furthermore, the ignition needle includes an ignition needle body and at least one mounting ring sleeved on the ignition needle body. The mounting ring protrudes from the outer side wall of the ignition needle body, and the foolproof part is disposed on the outer side wall of the mounting ring. The mounting ring is sleeved on the ignition needle body, or the mounting ring is integrally formed with the ignition needle body.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting the anti-fooling part on the outer side wall of the mounting collar, when the ignition needle is installed, the connecting element on the mounting bracket can abut against the mounting collar, thereby positioning the ignition needle in its axial direction and ensuring that the ignition tip of the ignition needle is located in the area near the opening of the first ignition hole.

[0015] Furthermore, the ignition needle includes an ignition needle body and at least one mounting collar sleeved on the ignition needle body. The mounting collar protrudes from the outer side wall of the ignition needle body, the foolproof surface is disposed on the outer side wall of the mounting collar, and the foolproof mating surface is formed by the surface of the fixing plate.

[0016] The advantage of adopting the above-mentioned further solution is that the surface of the fixing plate forms a foolproof mating surface, so there is no need to make additional design to the structure of the fixing plate. The fixing plate can adopt a simple flat plate structure, which makes the processing more convenient.

[0017] Furthermore, the outer peripheral surface of the mounting collar includes a mounting surface and a foolproof surface; along the circumference of the mounting collar, the distance from each point on the mounting surface to the axis of the mounting collar is the same, and the distance from at least a portion of the foolproof surface to the axis of the mounting collar is different from the distance from each point on the mounting surface to the axis of the mounting collar.

[0018] The advantage of adopting the above-mentioned further solution is that the distance from all points on the assembly surface to the axis of the mounting collar is the same, that is, the assembly surface is part of a circumferential surface. Figure 5 This illustrates the case where the assembly surface is part of a circumferential surface and the anti-fouling surface is a plane.

[0019] Furthermore, there are two mounting rings on the ignition needle, and each of the two mounting rings is provided with the anti-fooling part. The two mounting rings are spaced apart along the length direction of the ignition needle so as to accommodate the connecting element between the two mounting rings.

[0020] The beneficial effect of adopting the above-mentioned further solution is that when installing the ignition needle, the connecting element can be inserted between the two mounting rings, and the two ends of the connecting element abut against the two mounting rings respectively, which can better achieve the axial positioning of the ignition needle, and the two mounting rings can prevent the ignition needle from moving in its axial direction after installation, thus achieving stable installation of the ignition needle.

[0021] Furthermore, both the anti-mistake surface and the anti-mistake mating surface are either planes or curved surfaces, or a combination of both.

[0022] The advantage of adopting the above-mentioned further solution is that the shape of the anti-mistake surface and the anti-mistake mating surface can be varied. They can be mated between planes alone, between curved surfaces, or both planes and curved surfaces can be mated at the same time. Therefore, the surface shape of the anti-mistake surface and the anti-mistake mating surface can be selected according to the needs to obtain a better anti-mistake effect.

[0023] Furthermore, one of the second anti-foolproof part and the second anti-foolproof mating part is an anti-foolproof protrusion and the other is an anti-foolproof groove. The anti-foolproof matching between the second anti-foolproof part and the second anti-foolproof mating part is achieved through the concave-convex fit between the anti-foolproof protrusion and the anti-foolproof groove.

[0024] The beneficial effect of adopting the above-mentioned further solution is that, through the interlocking of the anti-mistake protrusion and the anti-mistake groove, the circumferential positioning of the ignition needle itself can be quickly achieved. Furthermore, the anti-mistake structure of the anti-mistake protrusion and the anti-mistake groove can clearly distinguish the anti-mistake area on the ignition needle and the anti-mistake area on the fixing plate.

[0025] Furthermore, the anti-mistake protrusion and the anti-mistake groove are strip-shaped, column-shaped, or sheet-shaped.

[0026] The advantage of adopting the above-mentioned further solution is that the shapes of the anti-mistake protrusions and anti-mistake grooves can be various, so the specific shapes of the anti-mistake protrusions and anti-mistake grooves can be selected according to needs.

[0027] Furthermore, the depth direction of the first ignition hole intersects with the axial direction of the first burner unit to form an acute angle; the length direction of the ignition needle intersects with the axial direction of the first burner unit to form an acute angle; and / or, the fixing plate intersects with the axial direction of the first burner unit to form an acute angle.

[0028] The beneficial effect of adopting the above-mentioned further scheme is that the first flame hole is set at an angle and each first flame hole forms a cone shape, thereby ensuring the flame concentration effect of the first burner unit, and thus improving the flame intensity and heating efficiency of the first burner unit.

[0029] Furthermore, the burner also includes a thermocouple, which is fixed to the mounting bracket.

[0030] The beneficial effect of adopting the above-mentioned further solution is that the thermocouple can be used to detect whether a flame is generated. When the flame in the first burner hole comes into contact with the tip of the thermocouple, the tip of the thermocouple can maintain a certain temperature and provide sufficient electromotive force to keep the solenoid valve on the gas pipeline of the burner open, so that the gas can enter the burner for combustion. In this way, the flame detection function of the thermocouple can be used to ensure the safety of the user during the use of the burner.

[0031] Furthermore, the burner also includes a mounting bracket, which has a fixing part and a mounting part. The first burner unit is connected to the mounting part, and the fixing bracket is connected to the fixing part.

[0032] The beneficial effect of adopting the above-mentioned further solution is that the first burner unit and the fixed bracket are both connected to the mounting bracket. Therefore, the first burner unit, the fixed bracket and the mounting bracket can be connected and fixed as a whole, and direct physical contact between the fixed bracket and the ignition needle on it and the first burner unit can be avoided, thereby improving the ignition success rate and safety.

[0033] Furthermore, the burner also includes a second burner unit, which has a plurality of second flame holes arranged in a ring, the plurality of second flame holes surrounding the outer side of the plurality of first flame holes.

[0034] The beneficial effect of adopting the above-mentioned further scheme is that the burner includes two combustion units, and the flame holes of the two combustion units are arranged radially along the burner, thus obtaining a larger combustion area and improving heating efficiency.

[0035] Furthermore, the first burner unit includes a first plate and a second plate, and a plurality of first flame holes are formed by the first plate and the second plate. The ignition needle is located on the side of the first plate away from the second plate. The edge of the first plate is provided with a notch, the notch is connected to the first flame hole and adjacent to the opening of the flame hole, and the ignition tip of the ignition needle is disposed close to the notch.

[0036] The beneficial effect of adopting the above-mentioned further solution is that a notch is provided on the edge of the first plate, and the notch is connected to the first ignition hole and adjacent to the opening of the ignition hole. The notch on the first plate corresponding to the ignition tip of the ignition needle can prevent the ignition needle from directly discharging on the first plate, thereby improving the ignition success rate.

[0037] The technical problem to be solved by this application is to provide a stove that can ensure the correct installation direction of the ignition needle.

[0038] The technical solution of this application to solve the above-mentioned technical problems is as follows: a stove, including a burner as described in any of the above technical solutions.

[0039] The beneficial effects of the stove described in this application are the same as those of the burner described above, and will not be repeated here. Attached Figure Description

[0061] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0062] In the relevant technology of burners, the ignition needle tip must be bent downwards to match the ignition discharge protrusion on the burner in order to improve the ignition success rate. If the ignition needle is not oriented correctly during actual assembly, ignition will easily fail.

[0063] In view of this, this application provides a burner, including a first burner unit, an ignition needle, and a fixing bracket; the first burner unit has a plurality of first flame holes; the ignition needle has a bent ignition tip extending to the vicinity of the opening of the first flame hole; the ignition needle is fixed to the fixing bracket for mounting to the burner via the fixing bracket; wherein, the ignition needle is provided with a foolproof part, and the fixing bracket is provided with a foolproof mating part, the foolproof part being used to match the foolproof mating part to achieve circumferential positioning of the ignition needle itself, so that the bending direction of the ignition tip faces the opening of the first flame hole. Through the cooperation between the foolproof part on the ignition needle and the foolproof mating part on the fixing bracket, the installation and fixing of the ignition needle and the fixing bracket can only be correctly achieved when the ignition needle is placed at a specific preset angle relative to the fixing bracket, thereby achieving foolproof installation of the ignition needle and improving the ignition success rate. The structure and function of the burner of this application are described in detail below with reference to the accompanying drawings.

[0064] Please see Figures 1 to 3 , Figure 1 This is a top view of an embodiment of the burner provided in this application. Figure 2 yes Figure 1 A radial sectional view of the burner. Figure 3 yes Figure 1 The exploded structure diagram of the burner 10 shows that the burner 10 includes a first burner unit 100, an ignition needle 220 and a fixed bracket 210. The first burner unit 100 has a plurality of first flame holes 110. The ignition needle 220 has a bent ignition tip 2210 that extends to the vicinity of the opening of the first flame hole 110. The ignition tip 2210 of the ignition needle 220 is used to provide sufficient energy instantaneously to ignite the mixed air at the first flame hole 110 to form a flame.

[0065] The ignition needle 220 and the fixing bracket 210 together constitute the ignition assembly 200. Please refer to [link / reference]. Figures 4 to 6 , Figure 4 yes Figure 1 A three-dimensional structural diagram of the ignition assembly 200 in the burner 10. Figure 5 yes Figure 4A three-dimensional structural diagram of the ignition needle 220 in the ignition assembly 200. Figure 6 yes Figure 4 A three-dimensional structural diagram of the fixing bracket 210 in the ignition assembly 200, wherein the ignition needle 220 is fixed to the fixing bracket 210 so as to be installed on the burner 10 through the fixing bracket 210.

[0066] The ignition needle 220 is provided with a foolproof part 2200, and the fixing bracket 210 is provided with a foolproof mating part 2110. The foolproof part 2200 is used to match the foolproof mating part 2110 to achieve the circumferential positioning of the ignition needle 220 itself, so that the bending direction of the ignition tip 2210 is towards the opening of the first flame hole 110. The circumferential positioning of the ignition needle 220 itself means that when the ignition needle 220 is installed on the fixing bracket 210, the cooperation between the foolproof part 2200 on the ignition needle 220 and the foolproof mating part 2110 on the fixing bracket 210 can prevent the ignition needle 220 from rotating about its own axis relative to the fixing bracket 210.

[0067] As can be seen, the ignition needle 220 of this application is provided with a foolproof part 2200, and the fixed bracket 210 is provided with a foolproof mating part 2110. Through the matching between the foolproof part 2200 and the foolproof mating part 2110, the foolproof installation of the ignition needle 220 relative to the fixed bracket 210 is realized, ensuring that the installation direction of the ignition needle 220 is correct. That is, after the ignition needle 220 is installed, the bending direction of the ignition tip 2210 of the ignition needle 220 is towards the opening of the first flame hole 110, so as to improve the ignition success rate.

[0068] In one embodiment, the fixing bracket 210 includes a fixing plate 211 and a connecting element 212 disposed on the fixing plate 211. The ignition needle 220 is fixed to the fixing plate 211 via the connecting element 212, and a foolproof mating part 2110 is disposed on the fixing plate 211. In this embodiment, the ignition needle 220 is fixed to the fixing plate 211 via the connecting element 212, which facilitates the installation and removal of the ignition needle 220 from the fixing plate 211, thereby facilitating the maintenance or replacement of the ignition needle 220. When installing the ignition needle 220, the foolproof mating between the ignition needle 220 and the fixing plate 211 ensures foolproof installation of the ignition needle 220. It can be understood that in other embodiments, the foolproof mating part 2110 may also be disposed on the connecting element 212, or simultaneously disposed on the fixing plate 211 and the connecting element 212, which can also achieve foolproof mating between the ignition needle 220 and the fixing bracket 210.

[0069] Specifically, the connecting element 212 includes two spring sheets 2120. The spring sheets 2120 and the fixing plate 211 can be integrally formed or separately set. A groove for accommodating the ignition needle 220 is formed between the two spring sheets 2120. The spring sheets 2120 adopt a sheet-like structure with a certain elastic deformation capability, such as a metal sheet. Since the connecting element 212 is in contact with the ignition needle 220, the connecting element 212 is in a high-temperature environment. The connecting element 212 can be made of a high-temperature resistant material, such as stainless steel. When installing the ignition needle 220, the ignition needle 220 is inserted into the groove between the two spring sheets 2120. The elastic deformation capability of the two spring sheets 2120 achieves stable clamping of the ignition needle 220.

[0070] See again Figure 6 The fixing plate 211 has a hole between the two springs 2120 to facilitate the installation of the two springs 2120. The foolproof mating part 2110 on the fixing plate 211 can be set in the hole area between the two springs 2120 or in an area other than the two springs 2120. For example, the plate surface on both sides of the two springs 2120 on the fixing plate 211 can be used as the foolproof mating part 2110.

[0071] In one embodiment, the error prevention part 2200 includes one or a combination of a first error prevention part and a second error prevention part. Correspondingly, the error prevention mating part includes one or a combination of a first error prevention mating part that can mate with the first error prevention part and a second error prevention mating part that can mate with the second error prevention part.

[0072] Please see Figures 7 to 9 , Figure 7 This is a cross-sectional schematic diagram along the radial direction of the ignition needle 220 in one embodiment of the burner 10 of this application and the fixing plate 211. Figure 7 This illustrates a case where the error prevention unit 2200 includes a first error prevention sub-unit 22001; Figure 8 This is a cross-sectional view along the radial direction of the ignition needle 220 in another embodiment of the burner 10 of this application, showing the ignition needle 220 and the fixing plate 211. Figure 8 This illustrates a case where the error-proofing unit 2200 includes a second error-proofing sub-unit 22002; Figure 9 This is a cross-sectional view along the radial direction of the ignition needle 220 in another embodiment of the burner 10 of this application, showing the ignition needle 220 and the fixing plate 211. Figure 9The illustration shows a case where the error-proofing part 2200 includes both a first error-proofing part 22001 and a second error-proofing part 22002. In this embodiment, the error-proofing part 2200 can employ one or more error-proofing parts. Correspondingly, the error-proofing mating part 2110 can employ one or more error-proofing mating parts. Therefore, the structures of the error-proofing part 2200 and the error-proofing mating part 2110 can have various options.

[0073] Furthermore, the relative positions of the first anti-foolproof part 22001 and the second anti-foolproof part 22002 can also be varied. For example, the first anti-foolproof part 22001 and the second anti-foolproof part 22002 can be offset axially from the ignition needle 220, or offset circumferentially from the ignition needle 220, or even... Figure 9 The second anti-foolproof part 22002 shown is located inside the first anti-foolproof part 22001.

[0074] Furthermore, the first anti-mistake part 22001 includes an anti-mistake surface, and the first anti-mistake mating part 21101 includes an anti-mistake mating surface. The anti-mistake surface and the anti-mistake mating surface are in a form-surface fit. A form-surface fit means that the shape of the anti-mistake surface matches the shape of the anti-mistake mating surface, and the two can fit completely together. In this embodiment, the anti-mistake surface and the anti-mistake mating surface are in a form-surface fit. When the ignition needle 220 is installed, as long as the anti-mistake surface and the anti-mistake mating surface are completely fitted, the anti-mistake fit between the ignition needle 220 and the fixing plate 211 can be achieved. Moreover, the anti-mistake structure is a surface-to-surface fit, which is convenient for processing and not easily damaged.

[0075] In one embodiment, the ignition needle 220 includes an ignition needle body 221 and at least one mounting collar 222. The mounting collar 222 protrudes from the outer side wall of the ignition needle body 221. A foolproof part 2200 is disposed on the outer side wall of the mounting collar 222. The foolproof part 2200 includes one or a combination of a first foolproof part 22001 and a second foolproof part 22002.

[0076] The mounting collar 222 can be fitted onto the ignition needle body 221. Therefore, the ignition needle body 221 can adopt the existing ignition needle structure without modification, and the mounting collar 222 can be fitted onto the outside of the ignition needle body 221. Since the mounting collar 222 is in contact with the ignition needle body 221 at a high temperature, the mounting collar 222 needs to be made of a high-temperature resistant material. This application does not specify the specific material of the mounting collar 222, as long as it can withstand high temperatures. The mounting collar 222 can also be integrally formed with the ignition needle body 221. Specifically, the mounting collar 222 can be co-sintered with the ceramic body of the ignition needle body 221 to facilitate the formation of the anti-fouling part 2200 on the outer wall of the mounting collar 222. In this application, the anti-foolproof part 2200 is disposed on the outer side wall of the mounting collar 222. When the ignition needle 220 is installed, the connecting element 212 on the fixing bracket 200 can abut against the mounting collar 222, thereby positioning the ignition needle 220 in its axial direction and ensuring that the ignition tip 2210 of the ignition needle 220 is located in the area near the opening of the first ignition hole 110.

[0077] Figures 4 to 6 The illustration shows a case where the anti-foolproof part 2200 on the ignition needle 220 uses a first anti-foolproof part 22001, and the first anti-foolproof part 22001 is an anti-foolproof surface. The anti-foolproof surface is located on the outer wall of the mounting collar 222. Corresponding to the anti-foolproof surface, the anti-foolproof mating surface on the fixing plate 211 is formed by the plate surface of the fixing plate 211. In this embodiment, a portion of the plate surface of the fixing plate 211 itself directly forms the anti-foolproof mating surface. Therefore, no additional design is required for the structure of the fixing plate 211. The fixing plate 211 can adopt a simple flat plate structure, making processing more convenient.

[0078] See again Figure 5 as well as Figures 7 to 9 The outer circumferential surface of the mounting collar 222 includes a mounting surface and a foolproof surface. Along the circumference of the mounting collar 222, the distance from all points on the mounting surface to the axis of the mounting collar 222 is the same. At least a portion of the foolproof surface has a different distance from the axis of the mounting collar 222 than the distance from all points on the mounting surface to the axis of the mounting collar 222. In this embodiment, the distance from all points on the mounting surface to the axis of the mounting collar 222 is the same, meaning the mounting surface is part of a circumferential surface. Figure 5 This illustrates the case where the assembly surface is part of a circumferential surface and the anti-fouling surface is a plane.

[0079] Furthermore, the ignition needle 220 has two mounting rings 222, each with a foolproof part 2200. The two mounting rings 222 are spaced apart along the length of the ignition needle 220 to accommodate the connecting element 212 between them. In this embodiment, when installing the ignition needle 220, the connecting element 212 can be engaged between the two mounting rings 222, with both ends of the connecting element 212 abutting against the two mounting rings 222 respectively. This better achieves axial positioning of the ignition needle 220, and the two mounting rings 222 prevent the ignition needle 220 from moving axially after installation, thus achieving stable installation of the ignition needle 220.

[0080] Corresponding to the structure of the two mounting rings 222 on the two ignition needles 220, in Figure 6 In the middle, the part of the plate surface of the fixed plate 211 on both sides of the two springs 2120 is the foolproof mating surface of the foolproof mating part 2110.

[0081] Combined Figures 7 to 10 , Figure 10 This is a cross-sectional view along the radial direction of the ignition needle 220 in another embodiment of the burner 10 of this application, showing the ignition needle 220 and the fixing plate 211. In some embodiments, the anti-misoperation surface and the anti-misoperation mating surface are either planes or curved surfaces, or a combination of both. In this embodiment, the shapes of the anti-misoperation surface and the anti-misoperation mating surface can be varied. They can be mated between planes alone, between curved surfaces, or both simultaneously. Therefore, the surface shapes of the anti-misoperation surface and the anti-misoperation mating surface can be selected as needed to obtain a better anti-misoperation effect. The specific surface shapes of the anti-misoperation surface and the anti-misoperation mating surface are chosen to facilitate the distinction between the anti-misoperation surface and the assembly surface of the ignition needle 220.

[0082] Figure 7 and Figure 9 It is shown that both the foolproof surface and the foolproof mating surface are planar. Figure 10 The diagram shows that both the anti-misalignment surface and the anti-misalignment mating surface are curved surfaces, which can be arc surfaces. One of the anti-misalignment surface and the other is a concave arc surface, and the other is a convex arc surface, to achieve a proper fit between their surfaces. It should be noted that when both the anti-misalignment surface and the anti-misalignment mating surface are arc surfaces, the radius of the arc surface is different from the radius of the assembly surface, to distinguish the anti-misalignment surface from the assembly surface of the outer circumference of the mounting collar 222. It is understood that in other embodiments, the curved surfaces of the anti-misalignment surface and the anti-misalignment mating surface can also be other curved surface shapes besides arc surfaces.

[0083] See again Figure 8 and Figure 9One of the second anti-mistake part 22002 and the second anti-mistake mating part 21102 is an anti-mistake protrusion and the other is an anti-mistake groove. The anti-mistake matching between the second anti-mistake part 22002 and the second anti-mistake mating part 21102 is achieved through the interlocking of the anti-mistake protrusion and the anti-mistake groove. In this embodiment, the interlocking of the anti-mistake protrusion and the anti-mistake groove can also quickly achieve the circumferential positioning of the ignition needle 220 itself. Furthermore, the anti-mistake structure of the anti-mistake protrusion and the anti-mistake groove can clearly distinguish the anti-mistake area on the ignition needle 220 and the anti-mistake area on the fixing plate 211.

[0084] Furthermore, the anti-mistake protrusions and anti-mistake grooves are strip-shaped, column-shaped, or sheet-shaped. In this embodiment, the shapes of the anti-mistake protrusions and anti-mistake grooves can be various, so the specific shapes of the anti-mistake protrusions and anti-mistake grooves can be selected as needed.

[0085] See again Figures 1 to 3 In one embodiment, the first burner unit 100 is an annular structure with an inner and outer periphery, and the openings of each first flame hole 110 are arranged along the inner periphery of the annular structure, with the first flame holes 110 of the first burner unit 100 arranged in a ring. It is understood that in other embodiments, the first burner unit 100 may have other structures, and the first flame holes 110 of the first burner unit 100 may not be arranged in a ring.

[0086] See again Figure 2 In one embodiment, the depth direction of the first flame hole 110 intersects the axial direction of the first burner unit 100 to form an acute angle. Further, the acute angle can be greater than or equal to 30°, and even further, it can be 40°, 50°, 60°, etc. In this embodiment, the first flame holes 110 are inclined, and each first flame hole 110 forms a cone shape, thereby ensuring the flame concentration effect of the first burner unit 100, and thus improving the flame intensity and heating efficiency of the first burner unit 100.

[0087] To accommodate the inclined arrangement of the first flame port 110, the length direction of the ignition needle 220 intersects with the axial direction of the first burner unit 100 at an acute angle; and / or, the fixing plate 211 intersects with the axial direction of the first burner unit 100 at an acute angle. The ignition needle 220 is positioned approximately along the length direction of the first flame port 110, which increases the overall compactness of the burner 10 structure. The angle formed between the length direction of the ignition needle 220 and the axial direction of the first burner unit 100 can be different from or the same as the angle formed between the depth direction of the first flame port 110 and the axial direction of the first burner unit 100.

[0088] See again Figures 1 to 4In one embodiment, the burner 10 further includes a thermocouple 230, which is fixed to a mounting bracket 210. The thermocouple 230 can be used to detect whether a flame is generated. When the flame in the first flame port 110 contacts the tip of the thermocouple 230, the tip of the thermocouple 230 maintains a certain temperature, providing sufficient electromotive force to keep the solenoid valve on the gas pipeline of the burner 10 open, allowing gas to enter the burner 10 for combustion. Thus, the flame detection function of the thermocouple 230 ensures user safety during the use of the burner 10. The thermocouple 230 can be fixed to the mounting bracket 210, and the thermocouple 230 can be clamped using the connecting element 212 described above, achieving the installation and fixation of the thermocouple 230 on the mounting bracket 210. In other embodiments, the thermocouple 230 can also be fixed to other parts of the burner 10.

[0089] See again Figure 1-3 In one embodiment, the burner 10 further includes a mounting bracket 300, which has a fixing portion 320 and a mounting portion 310. The first burner unit 100 is connected to the mounting portion 310, and the fixing bracket 210 is connected to the fixing portion 320. In this embodiment, both the first burner unit 100 and the fixing bracket 210 are connected to the mounting bracket 300. Therefore, the first burner unit 100, the fixing bracket 210, and the mounting bracket 300 can be connected and fixed as a whole, and direct physical contact between the fixing bracket 210 and its ignition needle 220 and the first burner unit 100 can be avoided, thus improving the ignition success rate and safety. Specifically, the connection and fixation between the first burner unit 100 and the mounting portion 310 of the mounting bracket 300, and the connection and fixation between the fixing bracket 210 and the fixing portion 320 of the mounting bracket 300, can be achieved using fasteners such as bolts.

[0090] Please see Figure 11 , Figure 11This is a partial enlarged view of the ignition tip 2210 of the ignition needle 220 in another embodiment of the burner 10 provided in this application. In one embodiment, the first burner unit 100 includes a first plate 101 and a second plate 102. A plurality of first flame holes 110 are formed by the first plate 101 and the second plate 102. The ignition needle 220 is located on the side of the first plate 101 away from the second plate 102. The edge of the first plate 101 is provided with a notch 1010. The notch 1010 communicates with the first flame holes 110 and is adjacent to the opening of the first flame holes 110. The ignition tip 2210 of the ignition needle 220 is disposed close to the notch 1010. In this embodiment, a notch 1010 is provided on the edge of the first plate 101, and the notch 1010 communicates with the first ignition hole 110 and is adjacent to the opening of the ignition hole. The notch 1010 on the first plate 101 corresponding to the ignition tip 2210 of the ignition needle 220 can prevent the ignition needle 220 from directly discharging onto the first plate 101, thereby improving the ignition success rate. It can be understood that in other embodiments, the first burner unit 100 may not have the notch 1010.

[0091] In one embodiment, after the first plate 101 and the second plate 102 are fitted together, a fixed connection between them can be achieved through welding. In another embodiment, the first plate 101 and the second plate 102 can also be connected by screwing. In other embodiments, the first plate 101 and the second plate 102 can also be connected by other processes, which are not specifically limited here. The first plate 101 and the second plate 102 can be made of stainless steel, copper alloy, or aluminum alloy. When stainless steel is used, it has advantages over copper, such as lower cost, longer service life, and a higher melting point for heat resistance. Furthermore, the first plate 101 and the second plate 102 can be formed in one piece by forging or stamping, improving processing efficiency.

[0092] Two notches 1010 can be provided on the first plate 101, with the ignition tip 2210 of the ignition needle 220 and the tip of the thermocouple 230 respectively positioned near one notch 1010. When the first burner unit 100 is in low flame state, the flame in the first flame hole 110 can contact the tip of the thermocouple 230 through the notch 1010 on the first plate 101 corresponding to the tip of the thermocouple 230, ensuring that the tip of the thermocouple 230 can always contact the flame, and avoiding the problem of flameout due to the thermocouple 230 not contacting the flame in the first flame hole 110 in low flame state.

[0093] Furthermore, the notch 1010 extends from the opening of the first flame hole 110 toward the root of the first flame hole 110. The opening and root of the first flame hole 110 mean that, along the depth direction (also the length direction) of the first flame hole 110, the first flame hole 110 has two ends, one of which is in communication with air so that the ignition needle 220 ignites the air mixture at that end to form a flame. This end is the opening of the first flame hole 110, and the end of the first flame hole 110 opposite to the opening is the root of the first flame hole 110.

[0094] Furthermore, the notch 1010 can be arc-shaped, rectangular, or square. In this application, the shape of the notch 1010 can be various, and the shape of the notch 1010 does not affect its function. It is understood that in other embodiments, the notch 1010 can also be other shapes.

[0095] In one embodiment, the notch 1010 corresponding to the ignition needle 220 extends along the depth direction of the first flame hole 110 to a depth not exceeding the ceramic body of the ignition needle 220. If the depth of the notch 1010 is too large, the flame may directly burn the ceramic body of the ignition needle 220, resulting in a flame color reaction, abnormal flame state, or red or yellowing. In this embodiment, the depth of the notch 1010 is no more than the ceramic body of the ignition needle 220, which can prevent the flame from directly burning the ceramic body of the ignition needle 220.

[0096] Furthermore, in order to improve the ignition success rate of the ignition needle 220, an ignition protrusion 1011 is formed on the inner periphery of the first burner unit 100. The ignition protrusion 1011 can be used to attract the electric arc generated by the ignition needle 220, so that the electric arc ignites the gas at the ignition protrusion 1011 to form a flame, thereby preventing the electric arc generated by the ignition needle 220 from running around and thus improving the ignition success rate of the first burner unit 100.

[0097] Please see Figures 12 to 14 , Figure 12 This is an exploded structural diagram of another embodiment of the burner 10 provided in this application. Figure 13 yes Figure 12 Top view of burner 10 Figure 14 yes Figure 13The burner 10 of this application includes a second burner unit 400, which has a plurality of second flame holes 410 arranged in a ring around the outside of a plurality of first flame holes 110. The second burner unit 400 can be connected to a mounting bracket 300 for fixed installation. In this embodiment, the burner 10 includes two combustion units, and the flame holes of the two combustion units are arranged radially along the burner 10, thus obtaining a larger combustion area and improving heating efficiency. In this embodiment, the plurality of first flame holes 110 and the plurality of second flame holes 410 can also be staggered along the axial direction of the burner 10, so that when the first burner unit 100 is successfully ignited, the second burner unit 400 can be ignited from the inner periphery by flame upward drawing. In other embodiments, the burner 10 may also include only a single first burner unit 100.
