[0038] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0040] In a first aspect, the present application embodiment provides a burner 10, see Figure 1 , Figure 1 A schematic structural diagram of a burner 10 according to an embodiment of the present application is shown. The burner 10 includes an inner combustion portion 11 , an outer combustion portion 12 and a diverter 13 .

[0041] See also Figure 3 , Figure 3 for Figure 1 The cross-sectional structure diagram of the burner 10 is shown, combined with Figure 1The inner combustion part 11 has an inner cavity 111 and an inner fire hole 112 connected to the inner cavity 111; the outer combustion part 12 is arranged on the outer side of the inner combustion part 11, and has an outer cavity 121 and an outer fire hole 122 connected to the outer cavity 121, and an air supply channel 14 is formed between the outer combustion part 12 and the inner combustion part 11. The flow divider 13 is located between the outer combustion part 12 and the inner combustion part 11, and divides the air supply channel 14 into a first channel 141 and a second channel 142. The first channel 141 is located between the flow divider 13 and the inner combustion part 11, and the first channel 141 is connected to the inner fire hole 112. The second channel 142 is located between the flow divider 13 and the outer combustion part 12, and the second channel 142 is connected to the outer fire hole 122.

[0042] The burner 10 of the embodiment of the present application is provided with a flow divider 13 between the inner combustion part 11 and the outer combustion part 12, and the flow divider 13 is used to separate the air supply channel 14 formed between the inner combustion part 11 and the outer combustion part 12 into a first channel 141 and a second channel 142, that is, the flow divider 13 is used to divert the air in the air supply channel 14, so that a part of the air is used to supply air to the combustion of the inner fire hole 112 connected to the first channel 141, and another part of the air is used to supply air to the combustion of the outer fire hole 122 connected to the second channel 142. In this way, on the one hand, the flow divider 13 orderly diverts the secondary air entering the burner 10 from the outside, so that the inner fire hole 112 and the outer fire hole 122 are connected to the second channel 142. During the combustion process, the hole 122 can fully replenish oxygen, making the burner 10 burn more completely, thereby reducing the generation of smoke; on the other hand, since the diverter 13 is arranged between the inner combustion part 11 and the outer combustion part 12, during the combustion process of the burner 10, the diverter 13 is affected by heat radiation and its own temperature is also relatively high. Therefore, the secondary air entering the burner 10 can fully contact with the diverter 13 and heat up in the process of reaching the inner fire hole 112 and the outer fire hole 122. When reaching the inner fire hole 112 and the outer fire hole 122, the temperature of the secondary air is relatively high, making the combustion process more intense and complete, thereby improving the combustion effect of the burner 10 as a whole.

[0043] See also Figure 2 , Figure 2 Shows Figure 1Schematic diagram of the explosion structure of the burner 10, the burner 10 may include a gas distribution plate 16, an inner ring fire cover 17 and an outer ring fire cover 18, the gas distribution plate 16 and the inner ring fire cover 17 are connected to form an inner combustion part 11, and the gas distribution plate 16 and the outer ring fire cover 18 are connected to form an outer combustion part 12. Among them, the gas distribution plate 16 can be an integrated structure or a split structure, which is not limited. For example, in an embodiment of the present application, the gas distribution plate 16 may include a first gas distribution plate 161 and a second gas distribution plate 162, the outer combustion part 12 is formed between the first gas distribution plate 161 and the outer ring fire cover 18, and the inner combustion part 11 is formed between the second gas distribution plate 162 and the inner ring fire cover 17, so that it is easy to disassemble and assemble the burner 10, and the convenience of replacing the various components of the burner 10 is improved.

[0044] In one embodiment, if the gas distribution plate 16 includes a first gas distribution plate 161 and a second gas distribution plate 162, the first gas distribution plate 161 can be provided with a first connecting member, and the second gas distribution plate 162 can be correspondingly provided with a second connecting member. The first gas distribution plate 161 and the second gas distribution plate 162 are connected and fixed by the first connecting member and the second connecting member to realize the assembly of the gas distribution plate 16.

[0045] The first connecting member and the second connecting member may be connected via a threaded connection via a locking member, or may be connected via plug-in connection, snap-fit ​​connection, etc., which is not limited thereto.

[0046] In the implementation of this application, Figure 1 and Figure 5 , Figure 5 The schematic diagram of the structure of the burner 10 in the embodiment of the present application from a bottom view is shown. The burner 10 also includes a connecting spoke 15 connected between the inner combustion part 11 and the outer combustion part 12. A spoke cavity 151 is provided in the connecting spoke 15. The spoke cavity 151 communicates with the inner cavity 111 and the outer cavity 121. The flow divider 13 is connected to the connecting spoke 15. By providing the connecting spoke 15, the inner combustion part 11, the outer combustion part 12 and the flow divider 13 can be connected by the connecting spoke 15, so as to improve the stability of the flow divider 13 between the inner combustion part 11 and the outer combustion part 12. Figure 3 The setting of the spoke cavity 151 can connect the inner cavity 111 with the outer cavity 121, so that the gas in the inner cavity 111 and the outer cavity 121 is mixed more evenly, thereby making the flame intensity of the inner fire hole 112 and the outer fire hole 122 more consistent when igniting, thereby improving the combustion uniformity of the burner 10.

[0047] Optionally, the connecting spokes 15 extend radially along the inner combustion portion 11, so that the arrangement path of the connecting spokes 15 between the inner combustion portion 11 and the outer combustion portion 12 is the shortest, which can reduce flow resistance. At this time, the exchange and flow of the mixed gas in the outer cavity 121 and the inner cavity 111 can be smoother.

[0048] It should be noted that the connecting spokes 15 connecting the inner combustion part 11 and the outer combustion part 12 can be: the connecting spokes 15 connecting the gas distribution plate 16, or the connecting spokes 15 connecting the inner ring fire cover 17 and the outer ring fire cover 18, which is not limited to this.

[0049] For example, in one embodiment, in combination Figure 2 , the connecting spoke 15 can be connected to the gas distribution disk 16. At this time, if the gas distribution disk 16 includes a first gas distribution disk 161 and a second gas distribution disk 162, the connecting spoke 15 can include a first connecting portion 153 and a second connecting portion 154. The first connecting portion 153 is connected to the first gas distribution disk 161, and the second connecting portion 154 is connected to the second gas distribution disk 162. A spoke cavity 151 is formed between the first connecting portion 153 and the second connecting portion 154. Dividing the connecting spoke 15 into the first connecting portion 153 and the second connecting portion 154 can facilitate the disassembly and assembly of the connecting spoke 15.

[0050] Further, see Figure 2 A convex strip 1531 can be provided on one side of the spoke cavity 151 formed by the first connecting portion 153. Thus, on the one hand, the convex strip 1531 can be utilized to enhance the structural strength of the first connecting portion 153, thereby enhancing the overall structural strength of the burner 10. On the other hand, since the convex strip 1531 is disposed between the inner combustion portion 11 and the outer combustion portion 12, during the combustion process of the burner 10, the convex strip 1531 has a relatively high temperature due to the heat radiation. Therefore, the primary mixed gas in the spoke cavity 151 can fully contact with the convex strip 1531 and be heated, thereby enhancing the preheating effect of the primary mixed gas and improving the combustion efficiency of the burner 10.

[0051] It should be noted that the first connection portion 153 and the first gas distribution plate 161 can be an integrated structure or a split structure; the second connection portion 154 and the second gas distribution plate 162 can be an integrated structure or a split structure, and this is not limited. Figure 2 The first connection part 153 and the first gas distribution plate 161 are an integrated structure, and the second connection part 154 and the second gas distribution plate 162 are an integrated structure. At this time, the first gas distribution plate 161 is connected to the second gas distribution plate 162, driving the first connection part 153 to be connected to the second connection part 154. In this way, after the gas distribution plate 16 is assembled, the connecting spokes 15 can be assembled, thereby improving the assembly efficiency of the burner 10.

[0052] In the present application embodiment, combined Figure 1 and Figure 5, a plurality of connecting spokes 15 can be provided, and the plurality of connecting spokes 15 are arranged at intervals around the circumference of the inner combustion part 11, and a third channel 152 connected to the air supply channel 14 is formed between each two adjacent connecting spokes 15. By providing a plurality of connecting spokes 15, the connection reliability between the inner combustion part 11 and the outer combustion part 12 can be further improved by using the plurality of connecting spokes 15, and the connection area between the flow divider 13 and the connecting spokes 15 can be further increased, thereby improving the stability of the flow divider 13 between the inner combustion part 11 and the outer combustion part 12. See again Figure 3 The spoke cavity 151 formed by the multiple connecting spokes 15 can further increase the ventilation area between the outer cavity 121 and the inner cavity 111, so that the gas in the inner cavity 111 and the outer cavity 121 is mixed more evenly, thereby improving the consistency of the flame intensity when the inner fire hole 112 and the outer fire hole 122 are ignited, and further improving the combustion uniformity of the burner 10.

[0053] The third channel 152 formed between every two adjacent connecting spokes 15 can be regarded as an air inlet for the air supply channel 14 to perform secondary air supply from the bottom.

[0054] In one embodiment, in combination Figures 2 to 4 , Figure 4 for Figure 3 In the partially enlarged schematic diagram of the A area in the burner shown, in order to improve the connection reliability between the diverter 13 and the connecting spoke 15, the diverter 13 can be provided with a protrusion 131 corresponding to the third channel 152, and the protrusion 131 extends into the third channel 152, so that the diverter 13 overlaps the connecting spoke 15. In this way, the position of the diverter 13 in the third channel 152 can be constrained by the protrusion 131, and the stability of the diverter 13 overlapping the connecting spoke 15 is improved.

[0055] It should be noted that the protrusion 131 can be inserted into the third channel 152 , or there can be a gap between the protrusion 131 and the third channel 152 , which is not limited to this.

[0056] In the present application embodiment, combined Figure 1 and Figure 2The flow divider 13 is arranged around the inner combustion part 11 in a whole circle or in sections. In this way, on the one hand, during the combustion process of the burner 10, oxygen can be further added to the inner fire hole 112 and the outer fire hole 122, so that the burner 10 burns more fully and reduces the generation of smoke; on the other hand, the contact area between the flow divider 13 and the secondary air can be further increased, and the secondary air can be preheated by using the higher temperature generated by the heat radiation of the flow divider 13 itself, so that the temperature of the secondary air is higher when it reaches the inner fire hole 112 and the outer fire hole 122, making the combustion process more intense and sufficient, and further improving the combustion effect of the burner 10 as a whole. If the flow divider 13 is arranged in sections around the inner combustion part 11, each section can be provided corresponding to at least one connecting spoke 15, so that each section can be overlapped on the connecting spoke 15, thereby improving the installation stability of the sections.

[0057] In one embodiment, the flow divider 13 includes a first flow divider 132 and a second flow divider 133 connected to each other, the second flow divider 133 is closer to the outer fire hole 122 than the first flow divider 132, the second flow divider 133 has a connection end 1331 connected to the first flow divider 132 and a free end 1332 away from the first flow divider 132, and the direction from the connection end 1331 to the free end 1332 is the fire direction of the inner fire hole 112. In this way, the second flow divider 133 will not hinder the fire of the inner fire hole 112, and the smoothness of the fire of the inner fire hole 112 can be improved.

[0058] Continue reading Figures 2 to 4 The outer fire hole 122 includes a first outer sub-fire hole 1221 and a second outer sub-fire hole 1222. The first outer sub-fire hole 1221 is arranged around the outer side of the second outer sub-fire hole 1222. The second outer sub-fire hole 1222 is arranged corresponding to the third channel 152 along the circumference of the outer combustion part 12, and is staggered with the connecting spoke 15. Since the air at the bottom will enter the air supply channel 14 through the third channel 152 during the secondary air supply, the gas flow at the third channel 152 is relatively large. At this time, the second outer sub-fire hole 1222 is arranged corresponding to the third channel 152, so that the second outer sub-fire hole 1222 can fully supplement oxygen during the combustion process, so that the burner 10 burns more fully, thereby reducing the generation of smoke.

[0059] Among them, the first outer sub-fire hole 1221 is arranged in a full circle around the circumference of the outer combustion part 12, so that the first outer sub-fire hole 1221 arranged in a full circle can be used to improve the combustion intensity of the burner 10, thereby improving the combustion efficiency of the burner 10. In addition, the ignition direction of the first outer sub-fire hole 1221 is toward the position where the inner combustion part 11 is located, and the ignition direction of the second outer sub-fire hole 1222 is toward the position where the outer combustion part 12 is located, so that the flame of the outer fire hole 122 and the flame of the inner fire hole 112 are staggered and burned, which can improve the uniformity of the combustion of the burner 10.

[0060] In addition, combined Figure 3 and Figure 4 When the flow divider 13 is used to supplement the combustion of the outer fire hole 122, specifically, the air in the air supplement channel 14 flows from the bottom to the top, first passing through the first flow divider 132 so that a part of the air enters the second channel 142. Since the direction from the connection end 1331 to the free end 1332 of the second flow divider 133 is roughly parallel to the end surface of the outer combustion part 12 provided with the outer fire hole 122, the second flow divider 133 can guide the air entering the second channel 142, thereby increasing the contact area between the secondary air and the flow divider 13. In this process, the secondary air in the second channel 142 first contacts with the first flow divider 132 to increase the temperature, and then contacts with the second flow divider 133 to continue to increase the temperature, so that when the secondary air reaches the outer fire hole 122, the temperature is relatively high, which can improve the preheating effect of the secondary air, thereby improving the combustion efficiency of the burner 10.

[0061] In the up and down direction, the outer combustion part 12 has a first bottom surface 123 away from the outer fire hole 122, and the diverter 13 has a lower end surface 134 away from the outer fire hole 122. The first bottom surface 123 is located below the lower end surface 134. In this way, when the air outside the burner 10 enters the air supply channel 14 through the first bottom surface 123, the lower end surface 134 of the diverter 13 will not occupy the area of ​​the air inlet at the bottom of the air supply channel 14, so that the gas flow rate entering the air supply channel 14 is larger, thereby better providing more sufficient air for the inner fire hole 112 and the outer fire hole 122 connected to the air supply channel 14 for their combustion.

[0062] Combination Figures 3 to 5 The bottom of the outer combustion part 12 has a first bottom surface 123 and an outer peripheral surface 124. The air supply channel 14 is arranged at the inner edge of the first bottom surface 123, and the outer peripheral surface is connected to the outer edge of the first bottom surface 123. From bottom to top, the distance between the outer peripheral surface 124 and the inner combustion part 11 gradually increases. In this way, the distance between the outer peripheral surface 124 and the inner combustion part 11 is the smallest near the first bottom surface 123, so that the air outside the burner 10 can enter the third channel 152 at the inner edge of the first bottom surface 123 from the top through the outer peripheral surface 124, and then enter the air supply channel 14 connected to the third channel 152, so as to improve the convenience of air intake during secondary air supply.

[0063] Along the up and down direction, the inner combustion part 11 has a second bottom surface 113 away from the inner fire hole 112, and the first bottom surface 123 is arranged lower than the second bottom surface 113. In this way, a height difference will be generated between the first bottom surface 123 and the second bottom surface 113. When the second bottom surface 113 contacts the table top of the gas stove, air can enter the third channel 152 and the air supply channel 14 through the gap formed by the height difference, thereby realizing the secondary air supplement for the combustion of the burner 10.

[0064] Furthermore, the second bottom surface 113 is parallel to the horizontal plane, so that the second bottom surface 113 is more stable when in contact with the tabletop of the gas stove, which can improve the stability of the burner 10 when placed.

[0065] The first bottom surface 123 , the second bottom surface 113 and the bottom surface of the connecting spokes 15 together constitute the bottom surface of the burner 10 .

[0066] In the second aspect, the embodiment of the present application provides a gas stove, which includes the above-mentioned burner 10. The specific structure of the burner 10 refers to the above-mentioned embodiment. Since the gas stove adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0067] In summary, the present application provides a burner 10 and a gas stove, which generate less smoke during use and have a better combustion effect.
