Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, in particular to a ignition distributor assembly and a burner. Background Art

[0002] The burner head of the burner is usually formed with an inner ring mixing chamber and an outer ring mixing chamber. There are two main relative positions and structures of the outer ring mixing chamber and the inner ring mixing chamber: one is that the outer ring mixing chamber surrounds the inner ring mixing chamber. Such a structure is widely used due to its advantages such as simple structure, small size and low cost. However, this structure has the defects of insufficient entrainment, insufficient blue flame and insufficient uniformity of flame. The other is that at least one outer ring mixing chamber is arranged on one side of the inner ring mixing chamber, and it is non-concentric with the inner ring mixing chamber. In particular, when multiple outer ring mixing chambers are arranged at equal intervals along the circumference of the inner ring mixing chamber, the outer ring flame formed is bluer and more uniform than the former flame. However, this structure usually adopts gravity casting or die casting, which has high process difficulty and low manufacturing efficiency. In addition, it still has the defects of low combustion efficiency and insufficient uniformity of flame.

[0003] Therefore, it is necessary to further optimize the burner head and make corresponding optimized designs for other parts of the burner, such as the fire cover assembly, the ejector tube assembly and the flame distributor assembly. Summary of the Invention

DETAILED DESCRIPTION

[0025] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0026] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0027] Figures 1 to 3 FIG. 1 shows a burner according to an embodiment of the present invention. Figure 2 and Figure 3 As shown, the burner may include an ejector tube assembly 1, a base assembly 2, an ignition distributor assembly 3, an inner ring ignition needle 4, an outer ring ignition needle 5, and a fire cover assembly 6, which are connected in sequence. The ejector tube assembly 1 may include at least one ejector tube body 11, and the base assembly 2 may include a base body 21 and at least one air inlet pipe 22 extending outward from the base body 21. The at least one ejector tube body 11 is arranged in a one-to-one correspondence with the at least one air inlet pipe 22 body. Each ejector tube body 11 may include a straight pipe section 111 and a diffuser section 112 connected to the straight pipe section 111. At least a portion of the diffuser section 112 extends into the air inlet pipe 22, and the diameter of the air inlet pipe 22 is larger than the diameter of the straight pipe section 111. The diameter of the diffuser section 112 gradually expands from the diameter of the straight pipe section 111 to the diameter of the air inlet pipe 22 along the flow direction of the gas, thereby reducing the turbulence caused by the gas impacting the air inlet pipe 22. Furthermore, the air inlet pipe 22 further extends the length of the ejector body 11, thoroughly mixing the gas (e.g., a mixture of air and gas) entering the ejector body 11. It will be appreciated that a nozzle 113 is provided at the end of the ejector body away from the diffuser section 112. When gas from the municipal pipeline enters the ejector body 11 through the nozzle 113, the negative pressure causes the primary air to enter through the nozzle 113, thereby forming a mixed gas of air and gas within the ejector body 11.

[0028] The ejector tube assembly 1 and base assembly 2 of the prior art typically comprise a split design with upper and lower parts secured by gluing and screws, resulting in a high degree of manufacturing difficulty. Compared to the prior art, the burner connection structure of the embodiment of the present invention utilizes a docking arrangement of the air inlet pipe 22 of the base assembly 2 and the diffuser section 112 of the ejector tube body 11. This ensures the integrity of the ejector tube body 11 while also maintaining its ejection and mixing capabilities, thus reducing manufacturing difficulty. Compared to the prior art, this reduces the number of parts and reduces costs by merging parts while maintaining performance.

[0029] Furthermore, the diffusion angle of the diffuser section 112 is 6° to 8°, effectively enhancing the diffusion effect of the diffuser section 112, thereby achieving more complete mixing of the gas and air mixture. The diameter of the intake pipe 22 is 1 to 2 times that of the straight pipe section 111. This ensures that the ejector tube body 11 has a wall thickness of sufficient strength while extending along the diffusion angle. The ejector tube can be extended sufficiently long, providing a strong ejection capability and ensuring complete mixing of the mixed gas, resulting in better performance. It is understood that a plane passing through the centerline of the diffuser section 112 cuts through the diffuser section 112 to form a cross-section of the diffuser section 112. In this cross-section, the angle defined by the inner wall of the diffuser section 112 (shown as two straight lines in this cross-section) is the diffusion angle of the diffuser section 112.

[0030] According to an exemplary embodiment of the connection between the base assembly 2 and the ejector tube assembly 1, as shown in FIG. Figures 1 to 3 As shown, the end of the air inlet pipe 22 away from the base body 21 ( Figures 1 to 3 A first connection portion 23 is provided at the right end of the intake pipe 22 shown or the starting end along the gas flow, and a second connection portion 12 is provided at the periphery of the connection between the diffuser section 112 and the straight pipe section 111, so that when the diffuser section 112 is inserted into the intake pipe 22, the second connection portion 12 is sealed and connected to the first connection portion 23.

[0031] Furthermore, first connecting holes 231 and second connecting holes 121 are provided at corresponding positions in the overlapping portions of the first connecting portion 23 and the second connecting portion 12. A first bolt is passed through the first connecting hole 231 and the second connecting hole 121 and then fastened with a first nut. By fixing the base assembly 2 and the ejector tube assembly 1 by docking, and providing a sealing ring 13 between the first connecting portion 23 and the second connecting portion 12, the process is simple and the sealing performance is good.

[0032] According to an exemplary embodiment of the intake pipe 22, as shown in FIG. Figure 2 As shown, at least one air inlet pipe 22 may include an outer ring air inlet pipe 221, and at least one ejector pipe body 11 may include an outer ring ejector pipe 114 at least a portion of which extends into the outer ring air inlet pipe 221. At least one air inlet pipe 22 may also include an inner ring air inlet pipe 222, and at least one ejector pipe body 11 may also include an inner ring ejector pipe 115 at least a portion of which extends into the inner ring air inlet pipe 222. It is understandable that the outer ring ejector pipe 114 and the inner ring ejector pipe 115 are arranged side by side and pass through the second connecting portion 12 at the same time. The outer ring ejector pipe 114 and the inner ring ejector pipe 115 both include a diffuser section 112 and a straight pipe section 111. Referring to the aforementioned connection method, when the diffuser section 112 of the outer ring ejector pipe 114 is inserted into the outer ring air inlet pipe 221, and the diffuser section 112 of the inner ring ejector pipe 115 is inserted into the inner ring air inlet pipe 222, the first connecting portion 23 and the second connecting portion 12 are fixedly connected.

[0033] According to an exemplary embodiment of the base body 21, as Figures 1 to 3 As shown, the base body 21 is surrounded by an inner ring gas mixing chamber 211. The inner ring gas mixing chamber 211 includes a first inner ring chamber 2111 and a second inner ring chamber 2112 stacked and connected from bottom to top. The cross section of the first inner ring chamber 2111 is fan-shaped, and the cross section of the second inner ring chamber 2112 is annular and is coaxially arranged with the first inner ring chamber 2111. The base body 21 is provided with a secondary air inlet 212, the cross section of the secondary air inlet 212 is fan-shaped and is arranged opposite to the first inner ring chamber 2111. The secondary air entering the middle of the inner ring gas mixing chamber 211 through the secondary air inlet 212 provides secondary air replenishment for the combustion of the inner ring flame, so that the mixed gas in the inner ring gas mixing chamber 211 can fully burn, reduce the yellow incomplete combustion flame, and make the inner ring flame bluer. The top of the second inner ring chamber 2112 is open and connected to the inner fire cover 61 of the fire cover assembly 6 (which will be described in detail below).

[0034] Furthermore, the first inner ring cavity 2111 and the secondary air inlet 212 extend 180° along the circumference of the base body 21 respectively, so that the secondary air inlet 212 and the first inner ring cavity 2111 can be combined to form a complete annular structure, providing more secondary air for the inner ring flame.

[0035] In order to form the first inner ring cavity 2111, as Figure 3 As shown, the base body 21 may further include a first inner ring inner wall 21111, a first inner ring outer wall 21112, a first inner ring bottom wall 21113, and two first inner ring side walls 21114 disposed in the same vertical plane. The two first inner ring side walls 21114 extend from the first inner ring inner wall 21111 in opposite directions along the radial direction of the base body 21 to the first inner ring outer wall 21112, forming a cylindrical structure with a cross-section that is a fan-shaped structure with a central angle of 180°. The bottom wall of this cylindrical structure is sealed by the first inner ring bottom wall 21113. The inner ring air inlet pipe 222 is connected to the outer periphery of the first inner ring cavity 2111 (the bottom portion of the circumferential center of the first inner ring outer wall 21112) and extends radially outward from the first inner ring cavity 2111 (toward the side away from the base body 21).

[0036] Continue to refer Figure 3The base body 21 further includes a second inner ring outer wall 21121, a second inner ring inner wall 21122, and a second inner ring bottom wall 21123. The second inner ring bottom wall 21123 is connected to the top of the first inner ring inner wall 21111 and extends horizontally. The second inner ring inner wall 21122 and the second inner ring outer wall 21121 continue to extend upward at positions corresponding to the first inner ring inner wall 21111 and the first inner ring outer wall 21112, respectively, and extend along the circumference of the base body 21, thereby forming an annular second inner ring cavity 2112 at the top of the first inner ring cavity 2111 and communicating with the first inner ring cavity 2111.

[0037] Further, refer to Figure 3 As shown, the base body 21 also includes an inner ring baffle 213 disposed on the first inner ring inner wall 21111 and extending horizontally outside the first inner ring cavity 2111. A certain distance is provided between the inner ring baffle 213 and the second inner ring bottom wall 21123, thereby defining a secondary air inlet 212 through the inner ring baffle 213, the second inner ring bottom wall 21123, and the two first inner ring sidewalls 21114. It will be appreciated that the height of the secondary air inlet 212 can be determined by the fuel gas ratio of the mixed gas within the inner ring mixing cavity 211. When a larger amount of secondary air is required, the distance between the inner ring baffle 213 and the second inner ring bottom wall 21123 can be appropriately increased.

[0038] Since only half of the components surrounding and forming the second inner ring cavity 2112 are supported on the components of the first inner ring cavity 2111, in order to improve the connection strength of the base body 21, as shown in FIG. Figure 3 As shown, the base body 21 may further include an inner ring support column 214 disposed in the middle of the secondary air inlet 212. The inner ring support column 214 extends downward from the second inner ring bottom wall 21123 to the inner ring support column 214, thereby supporting the components of the second inner ring cavity 2112 and the ignition distributor assembly 3 and the fire cover assembly 6 connected to the base body 21 together with the components of the first inner ring cavity 2111.

[0039] Continue to refer Figure 3 The base body 21 is also surrounded by a first outer ring gas mixing chamber 215 and a second outer ring gas mixing chamber 216 which are spaced apart along the circumference thereof and extend in the up-down direction respectively. The outer ring air inlet pipe 221 is connected to the first outer ring gas mixing chamber 215 and the second outer ring gas mixing chamber 216 respectively, thereby providing mixed gas to the second outer ring gas mixing chamber 216 and the first outer ring gas mixing chamber 215 in turn. Figure 3When viewed in the vertical direction, the outer ring air inlet pipe 221 is in a straight pipe shape, the first outer ring mixing chamber 215 is located at the distal end of the outer ring air inlet pipe 221, and the included angle between the first outer ring mixing chamber 215 and the second outer ring mixing chamber 216 is an acute angle, and the flow area of the first outer ring mixing chamber 215 is greater than that of the second outer ring mixing chamber 216, so that more mixed gas can enter the distal end of the air inlet pipe 22, so that when the base body 21 is connected with the igniter assembly 3, the gas flowing from the first outer ring mixing chamber 215 into the igniter assembly 3 can flow to the corresponding position of the second outer ring mixing chamber 216 in the clockwise direction, so that the gas mixing of the entire burner is more uniform, and the flame is more uniform.

[0040] According to an exemplary embodiment of the first outer ring mixing chamber 215, as shown in Figure 3 The first outer ring mixing chamber 215 has a first outer ring bottom wall 2151, and the starting end of the first outer ring bottom wall 2151 is connected to the end bottom wall of the air inlet pipe 22 and gradually rises in the gas flow direction in the circumferential direction of the base body 21, thereby forming a gradually raised gas flow height, preventing turbulence caused by the gas directly impacting the inner wall of the first outer ring mixing chamber 215.

[0041] Further, as shown in Figure 3 The first outer ring mixing chamber 215 can also include two first outer ring side walls 2152 spaced apart in the radial direction of the base body 21, and a first outer ring inner wall 2153 and a first outer ring outer wall 2154 spaced apart in the radial direction of the base body 21, the two first outer ring side walls 2152 respectively extend upward along the first outer ring bottom wall 2151, one of the two first outer ring side walls 2152 extends upward from the end of the outer ring air inlet pipe 221, and the other first outer ring side wall 2152 is arranged in the clockwise direction on the side of the first outer ring mixing chamber 215 away from the outer ring air inlet pipe 221. The flow area of the first outer ring mixing chamber 215 is defined by the two first outer ring side walls 2152, the first outer ring outer wall 2154, the first outer ring inner wall 2153, and the first outer ring bottom wall 2151.

[0042] According to an exemplary embodiment of the second outer ring mixing chamber 216, as shown in Figure 2 The second outer ring mixing chamber 216 includes two second outer ring side walls 2161 respectively extending upward from the outer ring air inlet pipe 221, and includes a second outer ring inner wall 2162 and a second outer ring outer wall 2163 spaced apart in the radial direction of the base body 21. The two second outer ring side walls 2161 are both arranged in the radial direction of the base body 21, and the second outer ring side wall 2161 downstream of the direction of gas flow in the outer ring air inlet pipe 221 (the left second outer ring side wall 2161 as shown in Figure 2 ) is arranged in the radial direction of the base body 21, and the first outer ring side wall 2152 (the right first outer ring side wall 2152 as shown in Figure 2The first outer ring side wall 2152 on the right side is arranged at intervals and the angle between the two is acute, so that the outer ring air inlet pipe 221 is connected with the second outer ring air mixing chamber 216 and then connected with the first outer ring air mixing chamber 215.

[0043] In the above embodiment, the second outer ring side wall 2161 ( Figure 2 The second outer ring side wall 2161 on the right side and the first outer ring side wall 2152 on the side away from the outer ring air inlet pipe 221 in the clockwise direction ( Figure 2 A base bracket is disposed between the second outer ring sidewall 2161 on the right side of the base body 21. This base bracket strengthens the walls of the first outer ring gas mixing chamber 215 and the second outer ring gas mixing chamber 216. Air passages are spaced apart on the base bracket to facilitate air flow into the interior of the base body 21, either from bottom to top or from outside to inside.

[0044] According to an exemplary embodiment of the fire distributor assembly 3, Figure 2As shown, the igniter assembly 3 includes an igniter body 31, a flame stabilizing ring 32, and an igniter baffle 33. The igniter body 31 has an annular igniter gas mixing chamber 311 and includes an igniter bottom wall 312, an igniter inner wall 313, and an igniter outer wall 314, which are respectively arranged on the bottom side, inner side, and outer side of the igniter gas mixing chamber 311. The igniter inner wall 313 includes an ignition hole portion 3131 extending at least a portion along its circumference. The igniter body 31 also includes an ignition extension portion 315 integrally formed with the ignition hole portion 3131. The ignition extension portion 315 extends radially into the igniter gas mixing chamber 311 of the igniter body 31. The igniter inner wall 313 is provided with a plurality of first ignition holes 31311 spaced apart from each other corresponding to the ignition hole portion 3131. The ignition extension portion 315 is provided with a third ignition hole 3151 that penetrates the first ignition hole 31311. The ignition extension portion 315 facilitates increasing the thickness of the first ignition hole 31311 provided on the inner wall 313 of the ignition divider, thereby making the gas output of the first ignition hole 31311 more uniform. A first ignition divider inlet 3121 corresponding to the first outer ring gas mixing chamber 215 and a second ignition divider inlet 3122 corresponding to the second outer ring gas mixing chamber 216 are provided on the bottom wall 312 of the ignition divider at intervals, allowing gas from the first outer ring gas mixing chamber 215 and the second outer ring gas mixing chamber 216 to enter the ignition divider gas mixing chamber 311 through the first ignition divider inlet 3121 and the second ignition divider inlet 3122, respectively. The first ignition hole 31311 and the third ignition hole 3151 are both provided at corresponding positions on the first ignition divider inlet 3121, allowing gas to enter the multiple first ignition holes 31311 through the ignition divider gas mixing chamber 311 through the first ignition divider inlet 3121. The second ignition divider inlet 3122 and the first ignition divider inlet 3121 are spaced apart from each other along the circumference of the ignition divider body 31 and extend from the ignition divider inner wall 313 to the ignition divider outer wall 314 , respectively.

[0045] According to an exemplary embodiment of the flame stabilizing ring 32, Figure 3As shown, the flame stabilizing ring 32 is connected to the inner wall 313 of the igniter, and has an overlapping portion with the inner wall 313 of the igniter, and the flame stabilizing ring 32 is provided with second ignition holes 321 corresponding to the overlapping portion and in one-to-one communication with the first ignition holes 31311, and the needle tip of the outer ring ignition needle 5 is arranged at the second ignition holes 321. The third ignition hole 3151, the first ignition hole 31311 and the second ignition hole 321 are in sequence and extend upwardly along the gas flow direction, so that when the flame stabilizing ring 32 is connected to the igniter body 31, the gas in the igniter mixing chamber 311 can pass through the third ignition hole 3151, the first ignition hole 31311 and the second ignition hole 321 in sequence. Specifically, the flame stabilizing ring 32 can include a flame stabilizing ring body 322, at least a portion of the outer peripheral wall of the flame stabilizing ring body 322 is fitted with the ignition hole portion 3131, and a plurality of second ignition holes 321 are arranged on the portion of the outer peripheral wall and in one-to-one communication with a plurality of first ignition holes 31311, so as to facilitate the arrangement of the outer ring ignition needle 5 in the area for ignition. Moreover, the flame stabilizing ring 32 can further include a flame stabilizing ring connecting portion 323 connected to the top of the flame stabilizing ring body 322, which extends outwardly along the radial direction of the flame stabilizing ring 32 to abut against the top of the inner wall 313 of the igniter. The top of the flame stabilizing ring connecting portion 323 has a first inclined surface 3231 and a second inclined surface 3232, the first inclined surface 3231 is configured to be flush with the inner peripheral surface of the outer fire cap 62 of the fire cap assembly 6 (which will be described in detail below), and the second inclined surface 3232 matches the inner end bottom surface of the outer fire cap 62, so that the flame stabilizing ring connecting portion 323 can be fully engaged with the inner periphery of the outer fire cap 62. More preferably, the flame stabilizing ring body 322 and the inner wall 313 of the igniter are fixed by riveting, and the first ignition hole 31311, the second ignition hole 321 and the third ignition hole 3151 are integrally formed in the ignition hole portion 3131, the flame stabilizing ring body 322 and the ignition extending portion 315 by riveting and then drilling. The flame stabilizing ring body 322 is made of copper, and the igniter body 31 is made of aluminum, so that the copper usage of the flame stabilizing ring body 322 is reduced, the processing difficulty is small, and the wall thickness of the aluminum igniter body 31 can be used to make the length of the ignition hole long enough to prevent flame separation, further reduce the cost and increase the amount of gas flowing through the ignition hole.

[0046] According to one exemplary embodiment of the igniter baffle 33, as Figure 2 and Figure 3As shown, the ignition divider baffle 33 is disposed between the first ignition divider inlet 3121 and the first ignition hole 31311. This reduces the flow rate of gas as it passes through the first ignition divider inlet 3121 and the ignition divider gas mixing chamber 311 into the first ignition hole 31311, thereby making the flame at the second ignition hole 321 more uniform. Specifically, the ignition divider baffle 33 is connected to the ignition divider inner wall 313 and extends horizontally from the ignition divider inner wall 313 into the ignition divider gas mixing chamber 311. The ignition divider baffle 33 is also vertically offset from the ignition divider bottom wall 312, thereby creating a vertical gap between the ignition divider bottom wall 312 and the ignition divider baffle 33 for gas to flow through. Furthermore, a gap exists between the vertical projections of the ignition divider baffle 33 and the bottom wall 312 of the ignition divider. That is, when viewed axially downward from the ignition divider body 31, a gap exists between the ignition divider baffle 33 and the bottom wall 312 of the ignition divider. This slightly increases the flow area of ​​gas between the ignition divider baffle 33 and the bottom wall 312, thereby further slowing the flow rate of gas. Preferably, this gap is 2 mm to 5 mm. Preferably, the ignition divider baffle 33 is integrally formed with the ignition divider body 31.

[0047] According to an exemplary embodiment of the fire cover assembly 6, Figures 1 to 3 As shown, the fire cover assembly 6 may include an inner fire cover 61 covering the top opening of the second inner ring cavity 2112 and an outer fire cover 62 covering the top opening of the ignition distributor mixing cavity 311 .

[0048] Figure 4 The inner fire cover 61 of the burner of the embodiment of the present invention is shown. Figure 3 and Figure 4 As shown, the inner fire cover 61 may include an inner fire cover body 611 and a shielding portion 612. The inner fire cover body 611 includes an inner fire cover inner wall 6111, an inner fire cover top wall 6112, and an inner fire cover outer wall 6113. The three walls enclose an annular or nearly annular inner fire cover cavity 6114 with an opening at the bottom and are respectively located on the inner side, top side, and outer side of the inner fire cover cavity 6114. A plurality of fire groove groups 61121 are arranged at intervals on the inner fire cover top wall 6112. A plurality of auxiliary fire holes 61111 are provided on the inner fire cover inner wall 6111 near the inner fire cover top wall 6112. The auxiliary fire holes 61111 can relieve the pressure of the gas in the inner fire cover cavity 6114 after all the fire groove groups 61121 are blocked by oil. When the gas at the fire groove groups 61121 burns normally, the gas at the auxiliary fire holes 61111 can also burn normally. The shielding portion 612 is provided on one side of the plurality of auxiliary fire holes 61111 close to the top wall 6112 of the inner fire cover ( Figure 3The inner wall 6111 of the inner fire cover is shown as being located above the plurality of auxiliary fire holes 61111 and connected to the inner wall 6111. The shielding portion 612 can block oil and dirt from above the inner fire cover top wall 6112 and prevent the auxiliary fire holes 61111 from being blocked. The inner fire cover outer wall 6113 is connected to the outer periphery of the inner fire cover top wall 6112 and is disposed corresponding to the inner fire cover inner wall 6111. The fire groove group 61121 of the inner fire cover top wall 6112 extends along the inner fire cover top wall 6112 from the inner fire cover inner wall 6111 to the inner fire cover outer wall 6113.

[0049] According to an exemplary embodiment of the inner wall 6111 of the inner fire cover, Figure 4 As shown, the inner wall 6111 of the inner fire cover includes a first region 61112 extending along at least a portion of its circumference, and a plurality of auxiliary fire holes 61111 are arranged at equal intervals along the circumference of the first region 61112. This allows the plurality of auxiliary fire holes 61111 to be concentrated in the first region 61112 of the inner wall 6111 of the inner fire cover, facilitating protection of the auxiliary fire holes 61111 by a relatively short shielding portion 612. Thus, the shielding portion 612 can be provided in the first region 61112 and extend radially inward from the inner wall 6111 of the inner fire cover. Furthermore, the shielding portion 612 may include a first end and a second end extending radially along the inner fire cover body 611, wherein the first end is close to the center of the inner fire cover body 611 and its length is less than the length of the second end, so that the shielding portion 612 is configured into a fan-shaped structure, thereby minimizing the blocking effect on the gas flowing through the center of the inner fire cover body 611, while also protecting the multiple auxiliary fire holes 61111.

[0050] According to a further exemplary embodiment of the inner fire cover 61, Figure 4 As shown, the inner fire cover 61 may also include a first baffle 613 extending inward from the bottom of the inner fire cover inner wall 6111. The first baffle 613 is provided with a first through-hole 6131 for air to pass through. Furthermore, the first baffle 613 is also provided with a second through-hole 6132 for the inner ring ignition needle 4 to pass through. The projections of the second through-hole 6132, the first through-hole 6131, and the shielding portion 612 on the first baffle 613 are staggered to prevent interference between the inner ring ignition needle 4 and the shielding portion 612, and to reserve sufficient circulation area for air circulation. When the burner is suitable for pots with a relatively pointed bottom, the first baffle 613 can resist and prevent the pot bottom from pressing the inner ring flame toward the base assembly 2, thereby burning components such as the base body 21.

[0051] According to an exemplary embodiment of the fire trough group 61121, as Figure 4As shown, the fire groove group 61121 includes a main fire groove 611211 and a flame stabilizing groove 611212 which are parallel and extend from the inner wall 6111 of the inner fire cover to the outer wall 6113 of the inner fire cover respectively, wherein the width of the main fire groove 611211 is greater than the width of the flame stabilizing groove 611212, thereby solving the flame separation problem of the inner ring flame.
