With continued reference to fig. 2, the fire cover 12 is disposed on the burner 11, and the fire cover 12 is disposed on the distributor 112. A third gas passage is provided in the fire cover 12 and should communicate with a second gas passage on the distributor 112 to supply gas to the fire cover 12 through the second gas passage.

Referring to fig. 3, the fire cover 12 includes a central fire cover 121 and an outer fire cover 122, the outer fire cover 122 is sleeved outside the central fire cover 121, the outer fire cover 122 and the central fire cover 121 are both located on the burner 11, the outer fire cover 122 and the central fire cover 121 are specifically disposed on the distributor 112, and the outer fire holes 1224 and the inner fire holes 1225 are both communicated with the second gas channel on the distributor 112, i.e. the third gas channel includes a central gas channel disposed in the central fire cover 121 and an outer gas channel disposed in the outer fire cover 122.

With continued reference to fig. 3, a central fire hole 1211 is provided on the central fire cover 121, and the central fire hole 1211 communicates with a central gas channel in the central fire cover 121 to provide gas through the central gas channel to the central fire hole 1211. The central fire cover 121 may have a cylindrical shape, and the central fire hole 1211 may be disposed on the annular wall 1212 of the central fire cover 121, and the annular wall 1212 of the central fire cover 121 is a cylindrical surface of the central fire cover 121.

With continued reference to fig. 3, the outer ring fire cover 122 has an outer ring gas channel therein, the outer ring fire cover 122 has a top wall 1222 and an outer ring wall 1221 far from the center fire cover 121, wherein the top wall 1222 is a wall surface indirectly contacting with the pot, and is also an upper surface of the outer ring fire cover 122, and the outer ring wall 1221 is an outer ring wall surface of the outer ring fire cover 122 far from the axis thereof when the burner 1 is in use.

With continued reference to fig. 3, an outer ring wall 1221 is provided with an outer ring fire hole 1224, a top wall 1222 is provided with an inner ring fire hole 1225 and a strip fire hole 1226, the inner ring fire hole 1225, the strip fire hole 1226 and the outer ring fire hole 1224 are all communicated with the outer ring gas channel, the inner ring fire hole 1225 is disposed on one side of the top wall 1222 near the center fire cover 121, the strip fire hole 1226 is disposed on one side of the inner ring fire hole 1225 far from the center fire cover 121, and the strip fire hole 1226 extends along the radial direction of the outer ring fire cover 122.

Referring to fig. 2 and 3, the burner 1 of the present application is sequentially provided with a central fire hole 1211, an inner annular fire hole 1225, a strip fire hole 1226 and an outer annular fire hole 1224 from inside to outside, and the four fire holes heat the pot through flames burning from inside to outside, wherein the flames in the strip fire hole 1226 can heat a flame blank area on the bottom surface of the pot, so that the flame coverage area on the bottom surface of the pot is increased when the burner 1 heats the pot, and the pot is heated more uniformly and has better use effect.

Referring to fig. 4, in some examples, the cross section of the strip fire hole 1226 may be rectangular, and the fire hole is easier to be processed, and only needs to be cut by a saw blade or milled by a milling cutter to form a corresponding fire hole. The cross section of the strip fire hole 1226 may be triangular or spindle-shaped, and the required effect of generating corresponding flames can be achieved.

With continued reference to fig. 4, in some examples, the strip fire holes 1226 may extend along the radial direction of the outer ring fire cover 122, where the extending direction of the strip fire holes 1226 is the opening direction of the strip fire holes 1226 on the top wall 1222, i.e. the direction opposite to the depth. The extending direction of the strip fire hole 1226 may coincide with the radius of the outer ring fire cover 122, or may form an included angle with the radius of the outer ring fire hole 1224. Regardless of the direction of extension, the strip fire hole 1226 should penetrate the top wall 1222 of the outer ring fire cover 122, and the strip flame is emitted from the outer ring fire hole 1224 to heat the annular flame blank area of the bottom surface of the pot.

In some examples, the distributor 112 and the outer ring fire cover 122 and the center fire cover 121 may be mounted by fixing members to ensure the mounting stability of the outer ring fire cover 122 and the center fire cover 121 and the distributor 112, and the tightness between the second gas channel and the outer ring gas channel and the inner ring gas channel after the mounting is completed.

Referring to fig. 5, in some examples, the center fire cover 121 and the outer ring fire cover 122 may be coaxially disposed. When the center fire cover 121 and the outer ring fire cover 122 are coaxially disposed, the center fire holes 1211, the inner ring fire holes 1225, the bar-shaped fire holes 1226 and the outer ring fire holes 1224 on the center fire cover 121 and the outer ring fire cover 122 may sequentially extend outward from the axis of the outer ring fire cover 122 to provide a uniform heating effect on the cookware.

In some examples, the central fire cover 121 and the outer ring fire cover 122 may be disposed differently, so that the central fire holes 1211, the inner ring fire holes 1225, the bar-shaped fire holes 1226 and the outer ring fire holes 1224 on the central fire cover 121 and the outer ring fire cover 122 heat the area above the central fire cover 121 with emphasis, and at this time, a better heating effect may be generated on the area with emphasis, which may satisfy the purpose that many cooks like to use obliquely when using the cooks, and may also satisfy the purpose of using non-uniform cooks. The non-uniform cookware can be cookware with non-uniform materials or cookware with irregular shapes.

With continued reference to fig. 5, in some examples, the center fire cover 121 has an upper wall 1213, i.e., an upper surface of the center fire cover 121. The upper wall 1213 of the center fire cover 121 and the top wall 1222 of the outer ring fire cover 122 may lie in the same plane, or in similar planes, disposed in parallel. In this way, the flames on the central fire cover 121 and the outer ring fire cover 122 can be located on the same plane or a relatively close plane, so that a good heating effect can be achieved on the pan and part of the convex bottom pan.

Referring to fig. 6, in some examples, the center fire cover 121 has an upper wall 1213. The upper wall 1213 of the center fire cover 121 is a plane, the top wall 1222 of the outer ring fire cover 122 is a conical surface, the strip fire holes 1226 are formed in the top wall 1222 of the conical surface, at this time, the center fire cover 121 and the outer ring fire cover 122 are coaxially arranged, and the conical surface of the outer ring fire cover 122 extends from inside to outside, that is, from the axis of the outer ring fire cover 122 to the outer ring wall 1221 of the outer ring fire cover 122, and the top wall 1222 is gradually far away from the burner 11. At this time, for the cone bottom cooker, the inner ring fire hole 1225, the strip fire hole 1226 and the outer ring fire hole 1224 on the outer ring fire cover 122 are sequentially far away from the burner 11, that is, the distances among the inner ring fire hole 1225, the strip fire hole 1226 and the outer ring fire hole 1224 are relatively close, so that the flames on the inner ring fire hole 1225, the strip fire hole 1226 and the outer ring fire hole 1224 can have a relatively good heating effect on the cooker.

In other examples, the first gas channel and the second gas channel each include two mutually independent sub-channels, and the sub-channels of the two first gas channels are in one-to-one correspondence and are communicated with the sub-channels of the two second gas channels, so as to respectively provide gas for the inner ring gas channel and the outer ring gas channel.

Referring to fig. 7, on this basis, the outer ring fire cover 122 further includes a plurality of first bosses 1227, the plurality of first bosses 1227 are distributed on the top wall 1222 around the axis of the outer ring fire cover 122, the number of the strip fire holes 1226 is plural, the plurality of first bosses 1227 are in one-to-one correspondence with the plurality of strip fire holes 1226, the strip fire holes 1226 are disposed on the top surfaces 12271 of the corresponding first bosses 1227, and an air channel is formed between two adjacent first bosses 1227.

Referring to fig. 8, the first boss 1227 may partially increase the height of the top wall 1222 of the outer ring fire cover 122, so that the strip fire hole 1226 may be easily processed without additional damage to other positions of the top wall 1222 when the wall thickness of the top wall 1222 is unchanged; meanwhile, the height of the first boss 1227 can be higher, so that air can be conveniently fed into the flame from a gap between the first boss 1227 and the top wall 1222, and the height of the flame can be improved, so that the cooker can be conveniently heated.

With continued reference to fig. 7 and 8, in some examples, the number of first bosses 1227 may be 3-20, preferably 10. And all of the first bosses 1227 may be uniformly distributed about the axis of the outer ring fire cover 122, thereby providing a relatively uniform heating effect of the first bosses 1227 on the pot.

With continued reference to fig. 7 and 8, in some examples, the width of the bar fire hole 1226 may be 0.5mm-2mm, preferably 0.8mm.

With continued reference to fig. 7 and 8, in some examples, the first boss 1227 may be a triangular pyramid stage, a triangular prism stage, or a trapezoidal stage, which may meet the requirements of use.

In some examples, all the first bosses 1227 may have the same shape, or may have different shapes, and the shapes of the first bosses 1227 may be regularly arranged, or may be irregularly arranged, so that the bar-shaped fire holes 1226 on the first bosses 1227 may burn out flames, thereby increasing the heating area of the burner 1 for the cookware.

Referring to fig. 9, the top surface 12271 is inclined, and the top surface 12271 gradually approaches the top wall 1222 along the axis of the outer ring fire cover 122 to the outer ring wall 1221. The top surface 12271 of the first boss 1227 gradually approaches the top wall along the axis of the outer ring fire cover 122 to the outer wall

1222, the outer ring wall 1221 is provided with an outer ring fire hole 1224, so that the flame at the position of the strip fire hole 1226 close to the outer ring wall 1221 can be connected with the flame of the gas combustion in the outer ring fire hole 1224, thereby preventing dead angles from being generated when the pot is heated, and enabling the heated area of the pot to be larger.

In some examples, the top surface 12271 can be planar or arcuate. Whether the top surface 12271 is a plane or a cambered surface or even an irregular surface, the corresponding strip-shaped fire holes 1226 can be formed in the top surface 12271, so that flames can be burnt at the strip-shaped fire holes 1226, and the heating area of the burner 1 on the cooker can be increased.

With continued reference to fig. 9, in some examples, the first boss 1227 has a top surface 12271, a transition surface 12272 that engages between the top surface 12271 and the top wall 1222, and inner side surfaces 12273 at the top surface 12271. The inner side 12273 should be the surface of the first boss 1227 facing the center fire cover 121. The number of transition surfaces 12272 should be two, so the first boss 1227 has five surfaces at this time.

With continued reference to fig. 9, in some examples, the top surface 12271 of the first boss 1227 contacts the top wall 1222 of the outer ring fire cover 122 in a point contact. I.e., the top surface 12271 of the first boss 1227 is a triangular surface with three sides on the two transition surfaces 12272 and the inner side surface 12273, respectively. At this time, the strip fire hole 1226 on the top surface 12271 may be completely located on the top surface 12271 or may be partially located on the top wall 1222, which may meet the requirements. At this point, an angle should exist between the top surface 12271 and the top wall 1222, which may be 5 ° -35 °, preferably 15 °.

In other examples, the top surface 12271 of the first boss 1227 is in contact with the top wall 1222 of the outer ring fire cover 122 in a line contact. I.e., the top surface 12271 of the first boss 1227 is a quadrilateral surface with four sides on the top wall 1222, the two transition surfaces 12272, and the inner side surface 12273, respectively. At this time, the strip fire hole 1226 on the top surface 12271 may be completely located on the top surface 12271 or may be partially located on the top wall 1222, which may meet the requirements.

In other examples, the top surface 12271 of the first boss 1227 does not contact the top wall 1222 of the outer ring fire cover 122. When the top surface 12271 of the first boss 1227 is not in contact with the top wall 1222, the top surface 12271, the transition surface 12272, and the top portion may also enclose a rear wall surface, where the first boss 1227 has six planes. At this time, the first boss 1227 may be one of a trapezoid table, a trapezoid-like table (a trapezoid table with a part of its surface being composed of cambered surfaces), a cuboid or a cuboid-like (a cuboid with a part of its surface being composed of cambered surfaces), and the top surface 12271 of the first boss 1227 may still be provided with a corresponding strip-shaped fire hole 1226, so that the strip-shaped fire hole 1226 burns flame, and the heating area of the burner 1 to the pot is increased.

In other examples, when the top surface 12271 of the first boss 1227 is not in contact with the top wall 1222, a ridge may be formed between the two transition surfaces 12272, and the first boss 1227 may have a triangular prism shape or a triangular prism-like shape (a triangular prism having a part of its surface formed by curved surfaces). However, this solution is generally not used because the strip fire hole 1226 on the top surface 12271 needs to pass through the first boss 1227 and the top wall 1222 when the first boss 1227 is fully raised, which is complicated to manufacture.

Referring to fig. 9 and 10, the first bosses 1227 have inner sides 12273, inner sides 12273 face the central fire cover 121, inner ring fire holes 1225 are disposed on the inner sides 12273, and at least one inner ring fire hole 1225 is disposed on each of the first bosses 1227. The inner ring fire hole 1225 is disposed on the inner side surface 12273 of the first boss 1227, so that the flame on the side of the strip fire hole 1226 close to the inner side surface 12273 can be connected with the flame generated by combustion of the gas in the inner ring fire hole 1225, thereby preventing dead angles from being generated on the inner side of the strip fire hole 1226 when the pot is heated, and enabling the heating area of the pot to be larger.

With continued reference to fig. 10, in some examples, the inner side surface 12273 of the first boss 1227 is connected to the inner annular wall 1223 of the outer annular fire cover 122, the inner annular wall 1223 of the outer annular fire cover 122 is an annular wall surface of the outer annular fire cover 122 facing the central fire cover 121, and an angle should be formed between the inner side surface 12273 of the first boss 1227 and the inner annular wall 1223 of the annular fire cover 12 so that the inner annular fire hole 1225 faces above the central fire cover 121. The included angle may be 15 ° -65 °, preferably 35 °.

In some examples, the inner side 12273 of the first boss 1227 can be planar or arcuate. When the inner side 12273 is planar, the inner side 12273 is more convenient to process and has low processing cost. When the inner side surface 12273 is a cambered surface, the inner side surface 12273 may be one of a concave surface and a convex surface, or may be an irregular surface, and the purpose of forming the inner ring fire hole 1225 on the inner side surface 12273 can be achieved no matter the inner side surface 12273 is a concave surface or a convex surface.

Referring to fig. 11, the inner side 12273 is inclined, and the distance between the edge of the inner side 12273 near the center fire cover 121 and the top wall 1222 is smaller than the distance between the edge of the inner side 12273 far from the center fire cover 121 and the top wall 1222. The inner side surface 12273 is an inclined surface, and is the direction from the axis of the outer ring fire cover 122 to the outer ring wall 1221 of the outer ring fire cover 122, and the inner side surface 12273 is gradually far away from the inclined surface of the burner 11, so that the flame of the inner ring fire hole 1225 faces the central area of the cooker, and the flame at the inner ring fire hole 1225 covers the annular area between the central fire hole 1211 and the strip fire hole 1226, so that the heating effect of the cooker is better.

In some examples, the inner side 12273 of each first boss 1227 can be a single side or a set of multiple adjacent sides.

Referring to fig. 12, in some examples, all of the first bosses 1227 are uniformly distributed about the axis of the outer ring fire cover 122, and all of the first bosses 1227 are the same size, shape, or similar, and all of the inner sides 12273 are also located on the same frustum. When the frustum is a conical frustum, the inner side surface 12273 is a cambered surface and is inclined inwards, and the cone angle of the conical frustum may be related to the inclination angle of the inner side surface 12273 of the first boss 1227, which may be equal or similar. When the frustum is a pyramid frustum, the number of edges of the pyramid frustum should be equal to the number of first bosses 1227, and the inner side 12273 is a plane.

With continued reference to fig. 12, in some examples, only a plurality of inner ring fire holes 1225 may be provided on each inner side 12273, and the number of the plurality of inner ring fire holes 1225 may be 2-5, preferably 3. At this time, each of the inner ring fire holes 1225 should communicate with the outer ring gas passage to supply gas to the inner ring fire holes 1225 through the outer ring gas passage.

At this time, 3 inner ring fire holes 1225 may be distributed around the axial direction of the outer ring fire cover 122, and the inner ring fire hole 1225 located in the middle among the 3 inner ring fire holes 1225 may communicate with the strip fire hole 1226, i.e., the strip fire hole 1226 extends from the side wall of the fire hole located in the middle of the 3 inner ring fire holes 1225 in the radial direction of the outer ring fire cover 122 toward the outer ring wall 1221 of the outer ring fire cover 122. When the gas burner is produced in this way, in the use process, the gas at the central fire hole 1211 can be ignited to form flame, then the flame is transmitted outwards to ignite the gas at the inner ring fire hole 1225, meanwhile, the gas at the strip fire hole 1226 communicated with the inner ring fire hole 1225 can be ignited synchronously, and finally, the flame is outwards ignited to ignite the flame of the outer ring fire hole 1224 through the extending direction of the strip fire hole 1226, so that the aim of expected automatic ignition and rapid ignition is achieved.

In other examples, the strip fire hole 1226 and the inner ring fire hole 1225 may not have the above-described communication relationship, i.e., the strip fire hole 1226 and the inner ring fire hole 1225 are independent of each other on the first boss 1227, and do not have a direct spatial connection. In this case, the flame of the inner ring flame hole 1225 and the flame of the strip flame hole 1226 can be separated more clearly, and the heating area is more clear.

Referring to fig. 13, the outer ring fire cover 122 further includes a plurality of second bosses 1228, the second bosses 1228 have a triangular pyramid shape, and the second bosses 1228 are disposed on the top wall 1222; the plurality of second bosses 1228 are in one-to-one correspondence with the plurality of first bosses 1227, each second boss 1228 being positioned between two adjacent first bosses 1227 such that the plurality of second bosses 1228 are distributed about the axis of the outer ring fire cover 122, with air passages being formed between adjacent first and second bosses 1227, 1228. The second boss 1228 is disposed on the top wall 1222, and an air passage is disposed between the second boss 1228 and the first boss 1227, so that the flame at the strip fire hole 1226 can supplement secondary air through air at the air passage during combustion, thereby enabling the combustion to be more sufficient and avoiding insufficient combustion.

With continued reference to fig. 13, in some examples, the first boss 1227 and the second boss 1228 may each be a protrusion provided on the top wall 1222, i.e., the highest height of the first boss 1227 and the highest height of the second boss 1228 are both higher than the height of the top wall 1222 in the axial direction of the outer ring fire cover 122 (in the opposite direction of the gravitational direction). At this time, the strip fire hole 1226 and the inner ring fire hole 1225 located on the first protrusion 1227 may be closer to the cookware mounted on the burner 1, and when the structure such as the pot holder 4 is mounted between the burner 1 and the cookware, the strip fire hole 1226 and the inner ring fire hole 1225 may have better heating effect on the cookware through the outer flame of the flame emitted by the strip fire hole.

In some examples, both the first boss 1227 and the second boss 1228 may be formed by casting. When the outer ring fire cover 122 body is cast, the cavity in the outer ring fire cover 122 can be cast conveniently to become an outer ring gas channel. Also, the outer ring fire cover 122 formed by casting may be set to have the wall thickness equal everywhere, at this time, it may be more convenient to cut the strip fire holes 1226 and the inner ring fire holes 1225 on the first boss 1227. The strip fire hole 1226 may be formed by sawing with a saw blade or milling with a milling cutter.

Meanwhile, the second boss 1228 formed by casting can be a hollow boss, so that the overall weight of the burner 1 is reduced, and the burner is more convenient to use and has fewer consumables.

With continued reference to fig. 13, in some examples, the number of second bosses 1228 is equal to the number of first bosses 1227, and one second boss 1228 is disposed between two adjacent first bosses 1227. There should be a gap between the ridge of the contact between the second boss 1228 and the top wall 1222 and the ridge of the contact between the first boss 1227 and the top wall 1222.

Referring to fig. 14, in some examples, the second boss 1228 has a shape similar to that of the first boss 1227, and may be one or more of a trapezoid table, a trapezoid-like table (trapezoid table with a part of its surface composed of cambered surfaces), a cuboid or a cuboid-like (cuboid with a part of its surface composed of cambered surfaces), a triangular prism or a triangular prism-like (triangular prism with a part of its surface composed of cambered surfaces).

In other examples, the second boss 1228 may be formed as a plurality of sub-bosses, as the primary function of the second boss 1228 herein is to separate the air flow between adjacent first bosses 1227, so that it flows along the gap between the second boss 1228 and the first boss 1227, so that a plane is formed with the second boss 1228 facing the first boss 1227.

In some examples, adjacent second bosses 1228 may or may not be physically connected. Whether or not there is a connection between the adjacent second bosses 1228, the adjacent second bosses 1228 should have a corresponding included angle for promoting air flow, and the air flows through the side walls of the two second bosses 1228 where the included angle is located by the included angle between the adjacent second bosses 1228, so as to achieve the air flow effect, and more secondary air can be supplemented through the channel when the flame burns.

Referring to fig. 15, on this basis, the number of the outer ring fire holes 1224 is set to be multiple, each outer ring fire hole 1224 includes multiple outer ring fire holes 1224, the multiple outer ring fire holes 1224 are distributed at intervals around the axis of the outer ring fire cover 122, and the gap between two adjacent outer ring fire holes 1224 is larger than the gap between two adjacent outer ring fire holes 1224, so that a first air filling channel is formed between two adjacent outer ring fire holes 1224. When the outer ring fire holes 1224 are arranged in multiple groups and gaps are left between adjacent groups, air at the gaps and air at the air channels can be communicated with each other, so that the air channels can supplement more oxygen for fuel gas.

With continued reference to fig. 13 and 15, in some examples, the number of sets of outer ring fire holes 1224 is not equal to the number of first protrusions 1227, and the first air supply channels between adjacent sets of outer ring fire holes 1224 and the air channels between the first protrusions 1227 and the second protrusions 1228 do not completely correspond. The outer ring fire holes 1224, the strip fire holes 1226 and the inner ring fire holes 1225 are all used for burning flames, so that when the burner 1 works at maximum power, the first air supplementing channels between the adjacent groups of the outer ring fire holes 1224 supplement air outside the burner 1 to the gas at the strip fire holes 1226 and the inner ring fire holes 1225, thereby improving the burning efficiency of the gas in the burner 1. The incomplete correspondence of the gaps between adjacent sets of outer ring fire holes 1224 and the air passages between the first protrusions 1227 and the second protrusions 1228 may be interpreted as partial air passages corresponding to the first air make-up passages, partial air passages may be interpreted as partial numbers of air passages, and may be interpreted as part of either air passage.

With continued reference to fig. 15, in this example, gaps are also left between the outer ring fire holes 1224 in each set of outer ring fire holes 1224, and these gaps can make the combustion at each outer ring fire hole 1224 relatively independent, so that the gas flowing direction and the air feeding amount in the adjacent outer ring fire holes 1224 are not affected on the premise of satisfying the mutual ignition, and the gas at the outer ring fire holes 1224 can also be combusted more fully.

In other examples, the number of sets of outer ring fire holes 1224 is equal to the number of first protrusions 1227, where the first air supply channels between adjacent sets of outer ring fire holes 1224 correspond one-to-one with the air channels between the first protrusions 1227 and the second protrusions 1228, and more air is supplied into the air channels through the first air supply channels. In this way, the number of outer ring fire holes 1224 is further reduced, resulting in a reduction in the overall power of the combustor 1. When the burner 1 supplements air only using the manner in the previous example, it may result in insufficient secondary air supplementation, and further insufficient gas combustion of the inner annular flame holes 1225, and by the first air supplementing passages and air passages in one-to-one correspondence in this example, the phenomenon of insufficient gas combustion at the inner annular flame holes 1225 and the strip flame holes 1226 may be alleviated.

Referring to fig. 16, a gap is left between the center fire cover 121 and the outer ring fire cover 122, and forms a second air supply channel, and an air supply hole 1121 communicating with the second air supply channel is provided in the distributor 112. The air outside the burner 1 may also enter the second air supplementing channel through the air supplementing hole 1121, and the second air supplementing channel enters the fire cover 12 area (i.e. the combustion area of the burner 1), firstly, directly contacts the central fire hole 1211 and the inner annular fire hole 1225 to supplement secondary air, so that the central fire hole 1211 and the inner annular fire hole 1225 supplement air, and then, the air channel supplements air for the strip fire hole 1226, so that the fuel gas in each area on the fire cover 12 can be combusted more fully in cooperation with the first air channel.

With continued reference to fig. 16, in some examples, the number of air make-up holes 1121 may be multiple, the number of air make-up holes 1121 may be 2-6, and all of the air make-up holes 1121 are not in contact with the second gas channel within the distributor 112. That is, the second gas channel and the air non-supplementing hole are both arranged on the distributor 112 and are isolated by the body of the distributor 112.

In some examples, the plurality of air make-up holes 1121 may be all and distributed about the axis of the distributor 112.

In some examples, the second air supplementing channel is provided with a flow guiding pipe distributed in the space where the second air supplementing channel is located, the flow guiding pipe penetrates through the outer wall of the distributor 112 and is communicated with the second gas channel, and the other end of the flow guiding pipe is communicated with the outer ring gas channel of the outer ring fire cover 122. The number of draft tubes may be set to be plural, and the plurality of draft tubes are distributed around the axis of the distributor 112.

Referring to fig. 17, the number of the central fire holes 1211 is set to be multiple, each group of central fire holes 1211 includes a plurality of central fire holes 1211, and the multiple groups of central fire holes 1211 are distributed around the axis of the central fire cover 121. When the center fire holes 1211 are provided in plural groups, the combustion power of the burner 1 can be increased by increasing the number of the center fire holes 1211 to thereby increase the flame power at the center fire holes 1211.

In some examples, the number of center fire holes 1211 in each set of center fire holes 1211 may be two or three.

Referring to fig. 18, in some examples, the sizes of the center fire holes 1211 in different groups may or may not be equal; the aperture of the center fire hole 1211 may be gradually reduced in a top-down direction along the axis of the center fire cover 121.

In some examples, a third protrusion may be provided on the center fire cover 121, and the center fire cover 121 may be matched with the pattern formed by the first protrusion 1227 and the second protrusion 1228 on the outer ring fire cover 122 by the third protrusion, so that it may look as a whole, and may have better aesthetic properties.

Referring to fig. 19, the central fire cover 121 has a ring wall 1212 adjacent to the outer ring fire cover 122, and a central fire hole 1211 is provided in the ring wall 1212; the annular protrusion 1214 is further provided on the annular wall 1212 of the center fire cover 121, the annular protrusion 1214 extends one circle around the circumference of the center fire cover 121, and the annular protrusion 1214 is provided on the side of the center fire hole 1211 remote from the burner 11. The annular protrusion 1214 is disposed on the annular wall 1212 and above the central fire hole 1211, so that the annular protrusion 1214 can shield the overflow when the pot overflows, thereby preventing the overflow from blocking the central fire hole 1211 to cause gas shutoff.

In some examples, the annular wall 1212 is a visor-like structure on the center fire cover 121 for shielding spills, primarily for protecting the center fire hole 1211 on the center fire cover 121. When the burner 1 is in use, a protection device is arranged in the burner 1, the central fire cover 121 of the burner 1 is the combustion area on which the flame is most basic, and the flame at the central fire hole 1211 on the central fire cover 121 is in a combustion state no matter which combustion mode is adopted.

Therefore, when the gas at the center fire cover 121 is not passed, the protection device detects the phenomenon and directly cuts off the gas supply to the entire burner 1, preventing the burner 1 from being dangerous. When the annular protrusion 1214 is provided above the center fire cover 121, a corresponding protection effect can be exerted on the center fire hole 1211 by the annular protrusion 1214.

In some examples, the burner 1 includes a central fire hole 1211, an inner annular fire hole 1225, a strip fire hole 1226 and an outer annular fire hole 1224, but only the central fire hole 1211 is provided with the annular protrusion 1214 to prevent the overflow from entering, and when the corresponding overflow entering in the inner annular fire hole 1225, the strip fire hole 1226 and the outer annular fire hole 1224 causes the phenomenon of flow break, the protection device is not triggered, the burner 1 still works normally, so that the user can continue cooking, and the use experience of the user is improved. After the user has finished cooking, the spills located in the inner ring fire holes 1225, the strip fire holes 1226 and the outer ring fire holes 1224 are cleaned.

Referring to fig. 20, the present application provides a stove, comprising a base 2, a burner 1, a panel 3 and a pan support 4; the burner 1 is the burner 1, the panel 3 is arranged on the base 2, the burner 1 is arranged in a space formed by the base 2 and the panel 3, a part of the burner 1 penetrates through the panel 3, the pot support 4 is arranged on the panel 3, and the pot support 4 is sleeved on a part of the burner 1 extending out of the panel 3. The cooker is placed on the cooker support 4, the burner 1 heats the cooker, and through the multi-ring flame from inside to outside, the heating area of the cooker is larger, the cooker is heated more uniformly, so that the heating effect of the cooker on the cooker is better, and the requirement of the user on the high heating power such as quick-frying is met.

With continued reference to fig. 20, in some examples, a plurality of burners 1 may be disposed on each stove, and a pot support 4 should be disposed on each burner 1, so that a plurality of burners 1 are used on the stove to heat a plurality of cookers, and the cookers are better in use effect.

With continued reference to fig. 20, in some examples, for a conventional household stove, two burners 1 and two pot holders 4 are collocated on each stove to heat two cookers simultaneously.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The foregoing is merely illustrative of specific embodiments of the present application, and the scope of the present application is not limited thereto, but any changes or substitutions within the technical scope of the present application should be covered by the scope of the present application.
