[0074] The gas distribution plate 200 according to an embodiment of this application is described below with reference to Figures 1-15.
[0075] Referring to Figures 3, 4, and 5, the gas distribution plate 200 according to an embodiment of this application includes: a first part 210 and a second part 220. The first part 210 defines a first gas passage 211. The second part 220 includes an inner ring part 221, an outer ring part 222, and a first connecting part 223. The inner ring part 221 is connected to the first part 210. At least a portion of the outer ring part 222 is located outside the inner ring part 221 and is spaced apart to define a first air passage 224. The first connecting part 223 is connected to the inner ring part 221 and the outer ring part 222 respectively. A second gas passage 225 is defined within the first connecting part 223. The second gas passage 225 has a first air outlet 2251 located in the outer ring part 222 and a first air inlet 2252 located in the inner ring part 221. The first part 210 and the second part 220 are integrally formed parts.
[0076] Referring to Figures 1, 2, and 3, in some specific application scenarios of this application, the gas distribution plate 200 is applied to the burner 1000. The burner 1000 also includes an inner flame cap 300 and an outer flame cap 400. The inner flame cap 300 is installed in the first part 210 and is connected to the first gas passage 211. The first gas passage 211 can guide the gas to the inner flame cap 300, and the gas is suitable for combustion at the inner flame cap 300 to form an inner ring flame. The outer flame cap 400 is installed in the outer ring part 222 and is connected to the first gas outlet 2251 of the outer ring part 222. The gas can enter the second gas passage 225 through the first gas inlet 2252 of the inner ring part 221, and then flow to the outer flame cap 400 through the first gas outlet 2251. The gas is suitable for combustion at the outer flame cap 400 to form an outer ring flame.
[0077] In this embodiment, the first portion 210 defines a first gas passage 211, and the second portion 220 defines a second gas passage 225. The first portion 210 and the second portion 220 are integrally molded, simplifying the structure of the gas distribution plate 200 and reducing its cost. Furthermore, compared to gas distribution plates 200 in related technologies that are assembled from multiple components, the gas distribution plate 200 in this embodiment is an integrally molded part, avoiding installation gaps at component connections, reducing the risk of gas leakage from the gas distribution plate 200, and improving the safety of the burner 1000.
[0078] Referring to Figures 3, 5, and 6, the first part 210 is located at the center of the entire gas distribution plate 200, making it suitable for connection with the inner burner cap 300. The inner ring part 221 is connected to the first part 210, so that the first air inlet 2252 is located near the first gas passage 211, facilitating the diversion of external gas. The simplified structure of the gas distribution plate 200 makes it easier to install. When the gas distribution plate 200 is working, the external gas is diverted at the connection between the inner ring part 221 and the first part 210. Part of the gas enters the first gas passage 211 and then flows to the inner burner cap 300, while the other part enters the first air inlet 2252 and then flows to the outer burner cap 400 through the second gas passage 225 and the first air outlet 2251.
[0079] It should be noted that the outer ring portion 222 being at least partially located outside the inner ring portion 221 means that, in a projection plane perpendicular to the thickness direction of the outer ring portion 222, the inner ring portion 221 is formed into a ring structure, and the outer ring portion 222 is also formed into a ring structure, with at least a portion of the outer ring portion 222 located outside the inner ring portion 221. This allows the outer ring portion 222 to be located outside the first portion 210, meaning that the outer flame cap 400 connected to the outer ring portion 222 can be located outside the inner flame cap 300. This allows the burner 1000 to form a multi-ring flame, improving the heating effect of the burner 1000.
[0080] It should also be noted that the inner ring portion 221 and the outer ring portion 222 can be a circular ring structure, or a rectangular ring structure, a regular octagonal ring structure, or a ring structure of other shapes. This application does not limit this.
[0081] Furthermore, in this embodiment, the outer ring portion 222 and the inner ring portion 221 are spaced apart to define the first air passage 224, so that outside air can enter between the outer ring portion 222 and the first portion 210 through the first air passage 224, thereby allowing outside air to enter between the outer burner cap 400 and the inner burner cap 300, providing air for the flame on the outer burner cap 400 and / or the inner burner cap 300, and improving the combustion efficiency of the burner 1000.
[0082] According to the embodiments of this application, the gas distribution plate 200 is a one-piece molded part, which simplifies the structure of the gas distribution plate 200, reduces the cost of the gas distribution plate 200, avoids installation gaps at the connection of parts, reduces the risk of gas leakage from the gas distribution plate 200, and improves the safety of the burner 1000. The inner ring portion 221 is connected to the first portion 210, so that the first air inlet 2252 is located near the first gas passage 211, which facilitates the diversion of external gas. The simplified structure of the gas distribution plate 200 facilitates the installation of the gas distribution plate 200. A first air passage 224 is provided between the outer ring portion 222 and the inner ring portion 221. The first air passage 224 can introduce outside air between the outer burner cap 400 and the inner burner cap 300, providing air for the flame on the outer burner cap 400 and / or the inner burner cap 300, thereby improving the combustion efficiency of the burner 1000.
[0083] Referring to FIG5, in some specific embodiments, the first part 210 defines a first gas passage 211. The first part 210 is also provided with a second air inlet 2111 and a second air outlet 2112 communicating with the first gas passage 211. The second air inlet 2111 is located near the first air inlet 2252 so that external gas can be diverted to the first air inlet 2252 and the second air inlet 2111.
[0084] The second air outlet 2112 and the first air outlet 2251 have the same opening orientation, so that the second air outlet 2112 can communicate with the inner burner cap 300 and the first air outlet 2251 can communicate with the outer burner cap 400, thereby improving the assembly efficiency of the air distribution plate 200 with the inner burner cap 300 and the outer burner cap 400.
[0085] In some embodiments, the outer ring portion 222 and the inner ring portion 221 are spaced apart in the thickness direction of the outer ring portion 222, and the outer ring portion 222 is located entirely outside the inner ring portion 221.
[0086] In the above technical solution, the outer ring portion 222 and the inner ring portion 221 are spaced apart in the thickness direction of the outer ring, so that the air around the gas distribution plate 200 can enter between the outer burner cap 400 and the inner burner cap 300 through the first air passage 224 between the outer ring portion 222 and the inner ring portion 221, thereby improving the combustion efficiency of the burner 1000.
[0087] The outer ring portion 222 being entirely outside the inner ring portion 221 means that, in a projection plane perpendicular to the thickness direction of the outer ring portion 222, the outer ring portion 222 is entirely outside the inner ring portion 221. This further increases the distance between the outer ring portion 222 and the first portion 210, and further increases the distance between the outer burner cap 400 and the inner burner cap 300, improving the uniformity of heating of the heated pot body and enhancing the heating effect of the burner 1000. Furthermore, it increases the flow area of the first air passage 224 and the amount of air within it, further improving the combustion efficiency of the burner 1000.
[0088] In some embodiments, the first connecting portion 223 extends in a straight line such that its two ends are connected to the outer ring portion 222 and the inner ring portion 221, respectively.
[0089] In this embodiment, the first connecting portion 223 extends along a straight line, simplifying its structure, reducing the difficulty of molding the gas distribution plate 200, and lowering its cost. The straight extension of the first connecting portion 223 also shortens the length of the second gas passage 225, improving its gas supply efficiency.
[0090] Referring to Figures 3, 4 and 7, in some embodiments, the first connecting portion 223 is a plurality of portions and is spaced circumferentially along the inner ring portion 221.
[0091] In this embodiment, the gas in the inner ring portion 221 can enter the outer ring portion 222 through multiple first connecting portions 223, which improves the flow efficiency of the gas in the second portion 220. Furthermore, the multiple first connecting portions 223 are arranged at intervals along the circumference of the inner ring portion 221, making the gas more evenly distributed in the outer ring portion 222, which further improves the combustion efficiency of the flame at the outer flame cap 400.
[0092] Referring to Figures 3 and 6, in some embodiments, the inner ring portion 221 has a first surface 2211 for defining a first air passage 224, and the outer periphery of the first surface 2211 away from the first portion 210 is provided with a guide ramp 2212 for guiding air toward the first air passage 224.
[0093] The above technical solution improves the efficiency of air entering the first air passage 224, thereby improving the combustion efficiency of the burner 1000.
[0094] In some embodiments, the first part 210 is provided with a second air passage 212, which is spaced apart from the first gas passage 211. The second air passage 212 is adapted to provide air to the flame on the inner burner cap 300, thereby improving the combustion efficiency of the flame on the inner burner cap 300 and further improving the heating effect of the burner 1000.
[0095] In some further embodiments, the second air passage 212 is connected to the first air passage 224.
[0096] In other words, the air in the first air channel 224 can be diverted to the second air channel 212, and then the second air channel 212 can provide air to the flame on the inner flame cap 300. In this embodiment, the way the second air channel 212 guides the air is simple, which simplifies the structure of the air distribution plate 200 and reduces the cost of the air distribution plate 200.
[0097] In some specific embodiments, the second air channel 212 penetrates the first portion 210 radially, thereby enabling the second air channel 212 to communicate with the first air channel 224. In this embodiment, the communication method between the second air channel 212 and the first air channel 224 is simple, simplifying the structure of the air distribution plate 200 and reducing its cost.
[0098] It should be noted that, in this embodiment, the first portion 210 is constructed as a ring shape, and the second air channel 212 extends along the radial direction of the first portion 210 and penetrates the first portion 210, thereby connecting the second air channel 212 with the first air channel 224. In other embodiments, the first portion 210 may also be a rectangular ring shape, a regular octagonal ring shape, or a ring shape of other shapes. In such embodiments, the extension direction of the second air channel 212 is perpendicular to the thickness direction of the outer ring portion 222 and penetrates the first portion 210, thereby connecting the second air channel 212 with the first air channel 224.
[0099] In some applications, when the burner 1000 is operating, a portion of the combustion gas flows through the first section 210 to the inner burner cap 300 and burns there, while another portion flows through the second section 220 to the outer burner cap 400 and burns there. The flame combustion heats the air above the burner 1000, causing it to rise and attract air from around the burner 1000 towards the inner and outer burner caps. A portion of this air enters the first air passage 224 through the gap between the inner and outer ring sections 221 and 222. The air in the first air passage 224 is divided into two parts: one part flows directly upwards to the space between the outer and inner burner caps 400, providing air for the flames on the outer and / or inner burner caps 300; the other part flows to the second air passage 212, providing air for the flames on the inner burner cap 300, effectively improving the combustion efficiency of the burner 1000.
[0100] In some embodiments, the second air passage 212 has a first bottom wall 2121 that is not higher than the first surface 2211 of the inner ring portion 221 that defines the first air passage 224.
[0101] Through the above technical solution, the air in the first air channel 224 can be directly diverted to the second air channel 212, which improves the smoothness of air flow.
[0102] In some specific embodiments, the first bottom wall 2121 is flush with the first surface 2211, which facilitates the mold opening of the air distribution plate 200 and reduces the difficulty of integral molding of the air distribution plate 200.
[0103] Referring to Figures 3 and 6, in some embodiments, the first connecting portion 223 is used to divide the space between the inner edge of the outer ring portion 222 and the outer edge of the inner ring portion 221 into a plurality of air through holes 2241, which are connected to the first air channel 224. A plurality of second air channels 212 are also provided, with each of the plurality of air through holes 2241 corresponding to one of the plurality of second air channels 212.
[0104] Air around the air distribution plate 200 is suitable to enter the first air channel 224 through multiple air through holes 2241. In this embodiment, multiple air through holes 2241 and multiple second air channels 212 are arranged in a one-to-one correspondence, so that air entering the first air channel 224 through the air through holes 2241 can be easily diverted to the corresponding second air channel 212, thereby improving the air flow efficiency.
[0105] Referring to Figures 6, 7 and 8, in some specific embodiments, the connecting area of the second air channel 212 is smaller than the opening area of the corresponding air via 2241.
[0106] In this embodiment, the connecting area of the second air channel 212 is smaller than the opening area of the corresponding air through hole 2241, which facilitates the integrated core extraction of the first air channel 224 and the second air channel 212 during the production process of the air distribution plate 200, and reduces the difficulty of mold opening of the air distribution plate 200.
[0107] Referring to Figures 3, 5, and 6, in some specific embodiments, the first portion 210 includes a central ring 213, an outer ring 214, and a second connecting portion 215. The central ring 213 is located inside the outer ring 214, and the second connecting portion 215 is connected to both the central ring 213 and the outer ring 214. A first gas passage 211 is defined between the outer peripheral wall of the central ring 213, the inner peripheral wall of the outer ring 214, and the second connecting portion 215. A second air passage 212 is provided within the second connecting portion 215, and the second air passage 212 has an air inlet 2151 located in the outer ring 214 and an air outlet 2152 located in the central ring 213.
[0108] In this embodiment of the application, when the gas stove is working, the air around the burner 1000 can enter the first air passage 224. The air in the first air passage 224 is divided into two parts. One part of the air flows directly upward to the space between the outer burner cap 400 and the inner burner cap 300 to provide air for the flame on the outer burner cap 400 and / or the inner burner cap 300. The other part of the air is divided into the second air passage 212 through the air inlet 2151. The air in the second air passage 212 enters the space radially inside the central ring 213 through the air outlet 2152, and then flows upward to the inner burner cap 300 to provide air for the flame on the inner burner cap 300.
[0109] It should be understood that, in some embodiments, the air below the first part 210 can also flow directly upward through the space radially inside the central ring 213 to the inside of the inner burner cap 300, providing air for the flame on the inner burner cap 300, further improving the combustion efficiency of the burner 1000.
[0110] This application proposes a burner.
[0111] Referring to Figures 1, 2, and 3, the burner 1000 according to an embodiment of this application includes: a gas distribution plate 200, a burner head structure 100, an inner burner cap 300, and an outer burner cap 400. The gas distribution plate 200 is the same as the gas distribution plate 200 in the above-mentioned technical solution. The burner head structure 100 defines a gas receiving cavity 111. A first gas passage 211 and a second gas passage 225 are both connected to the gas receiving cavity 111. The first gas passage 211 is also connected to the inner burner cap 300, and the second gas passage 225 is also connected to the outer burner cap 400.
[0112] When the burner 1000 is working, the gas in the gas receiving cavity 111 is diverted to the first gas passage 211 and the second gas passage 225. The first gas passage 211 can guide the gas to the inner burner cap 300, where the gas is suitable for combustion to form an inner ring flame. The second gas passage 225 can guide the gas to the outer burner cap 400, where the gas is suitable for combustion to form an outer ring flame.
[0113] According to the embodiments of the present application, the burner 1000 has a gas distribution plate 200 that is integrally molded, which simplifies the structure of the gas distribution plate 200, reduces the cost of the gas distribution plate 200, avoids installation gaps at the connection of parts, reduces the risk of gas leakage from the gas distribution plate 200, and improves the safety of the burner 1000. The inner ring portion 221 is connected to the first portion 210, so that the first air inlet 2252 is located near the first gas passage 211, which facilitates the gas diversion in the gas receiving cavity 111. The simplified structure of the gas distribution plate 200 facilitates the assembly of the gas distribution plate 200 with the burner head structure 100. A first air passage 224 is provided between the outer ring portion 222 and the inner ring portion 221. The first air passage 224 can introduce outside air between the outer flame cap 400 and the inner flame cap 300, providing air for the flame on the outer flame cap 400 and / or the inner flame cap 300, thereby improving the combustion efficiency of the burner 1000.
[0114] In some embodiments, the inner flame cover 300 is provided with a plurality of first flame holes 310, the plurality of first flame holes 310 are distributed at intervals along the circumference of the inner flame cover 300, and each first flame hole 310 extends obliquely toward the center of the inner flame cover 300.
[0115] When the burner 1000 is working, the gas in the first gas passage 211 burns on the inner flame cap 300 after passing through the first flame hole 310. Because each first flame hole 310 extends at an angle toward the center of the inner flame cap 300, the flame on the inner flame cap 300 is formed into a cohesive flame, which improves the heating effect of the burner 1000.
[0116] It should be understood that the flame holes on the inner flame cover 300 can also be set upwards or in a direction away from the center of the inner flame cover 300, and this application does not limit this.
[0117] In other embodiments, a plurality of first flame holes 310 are provided on the radially inner side of the inner flame cover 300, and the plurality of first flame holes 310 are distributed at intervals along the circumference of the inner flame cover 300. Each first flame hole 310 extends obliquely toward the center of the inner flame cover 300. A plurality of second flame holes are provided on the radially outer side of the inner flame cover 300, and the plurality of second flame holes are distributed at intervals along the circumference of the inner flame cover 300.
[0118] When the burner 1000 is operating, a portion of the gas in the first gas passage 211 passes through the first flame hole 310 and burns radially inward on the inner burner cap 300, forming a ring flame. Another portion of the gas in the first gas passage 211 passes through the second flame hole and burns radially outward on the inner burner cap 300, forming another ring flame. In other words, two ring flames can be formed on the inner burner cap 300. It should be understood that the flame holes on the inner burner cap 300 can also be arranged in other ways to allow multiple ring flames to be formed on the inner burner cap 300; this application does not limit this arrangement.
[0119] In some embodiments, the outer flame cover 400 is provided with a plurality of third flame holes 410, the plurality of third flame holes 410 being distributed at intervals along the circumference of the outer flame cover 400, and each third flame hole 410 extending obliquely toward the center of the outer flame cover 400.
[0120] When the burner 1000 is working, the gas in the first gas passage 211 burns on the outer flame cap 400 after passing through the third flame hole 410. Because each third flame hole 410 extends at an angle toward the center of the outer flame cap 400, the flame on the outer flame cap 400 is formed into a cohesive flame, which improves the heating effect of the burner 1000.
[0121] It should be understood that the flame holes on the outer flame cover 400 can also be set facing upwards or in a direction away from the center of the outer flame cover 400, and this application does not limit this.
[0122] In other embodiments, a plurality of third flame holes 410 are provided on the radially inner side of the outer flame cover 400, and the plurality of third flame holes 410 are distributed at intervals along the circumference of the outer flame cover 400. Each third flame hole 410 extends obliquely toward the center of the outer flame cover 400. A plurality of fourth flame holes are provided on the radially outer side of the outer flame cover 400, and the plurality of fourth flame holes are distributed at intervals along the circumference of the outer flame cover 400.
[0123] When the burner 1000 is operating, a portion of the gas in the second gas passage 225 passes through the third flame hole 410 and burns radially inward on the outer flame cap 400, forming a ring flame. Another portion of the gas in the second gas passage 225 passes through the fourth flame hole and burns radially outward on the outer flame cap 400, forming another ring flame. In other words, two ring flames can be formed on the outer flame cap 400. It should be understood that the flame holes on the outer flame cap 400 can also be arranged in other ways to allow multiple ring flames to be formed on the outer flame cap 400; this application does not limit this arrangement.
[0124] Referring to Figures 2, 9, and 10, in some embodiments, the burner structure 100 includes: a main body 110, a partition assembly 120, and an ejector tube 130. The main body 110 contains a gas receiving cavity 111. The partition assembly 120 is disposed within the main body 110 and located within the gas receiving cavity 111. The partition assembly 120 divides the gas receiving cavity 111 into multiple sequentially nested cavities, with adjacent cavities connected. The multiple cavities are adapted to communicate with multiple burner caps. The ejector tube 130 is disposed within the main body 110 and communicates with each of the multiple cavities.
[0125] It should be noted that the nested multiple cavities refer to the following: the partition component 120 divides the gas receiving cavity 111 into two cavities, namely the first cavity 112 and the second cavity 113. The second cavity 113 is fitted over the first cavity 112. The first cavity 112 is connected to the inner burner cap through the first gas passage, and the second cavity 113 is connected to the outer burner cap through the second gas passage.
[0126] In some application scenarios, the gas stove nozzle 500 is set directly opposite the inlet end of the injector tube 130. Multiple cavities are connected to multiple burner caps respectively, and the multiple cavities correspond one-to-one with the multiple burner caps. Each cavity is connected to one burner cap, and each burner cap is provided with a flame hole. Because the multiple cavities are nested sequentially, the multiple burner caps are also set to be nested sequentially.
[0127] When the gas stove is working, the nozzle 500 of the gas stove sprays gas towards the inlet end of the injector tube 130. The gas carries the air around the injector tube 130 into the injector tube 130, and then enters the gas receiving chamber 111 through the outlet end of the injector tube 130. Because the injector tube 130 is connected to multiple chambers, the gas in the injector tube 130 is discharged from the outlet end and then distributed to multiple chambers. The gas in each chamber flows to the corresponding burner cap and is discharged from the burner cap's flame hole. After the gas is discharged from the flame hole, it burns to form a flame, and multiple ring flames are formed on the sequentially nested burner caps.
[0128] It should be noted that the ejector tube 130 is connected to multiple cavities. This connection can be direct with all cavities, or it can be direct with some cavities and indirect with others. For example, in some embodiments, the separator 120 divides the gas receiving cavity 111 into two cavities: a first cavity 112 and a second cavity 113, with the second cavity 113 fitted over the first cavity 112. The ejector tube 130 is directly connected to both the first and second cavities. In this embodiment, the gas in the ejector tube 130 is directly diverted to the first and second cavities after exiting from the outlet.
[0129] In other embodiments, the separating component 120 divides the gas receiving chamber 111 into two chambers, namely a first chamber 112 and a second chamber 113, with the second chamber 113 fitted over the first chamber 112. The ejector tube 130 is directly connected to the second chamber 113, and the second chamber 113 is connected to the first chamber 112, thus creating a spaced communication between the ejector tube 130 and the first chamber 112. In this embodiment, the gas in the ejector tube 130 flows from its outlet to the second chamber 113, and then from the second chamber 113 to the first chamber 112.
[0130] The goal is simply to ensure that the ejector tube 130 is connected to multiple cavities. In other words, the gas in the ejector tube 130 can be directly distributed to multiple cavities after being discharged from the outlet end, or it can be distributed to cavities indirectly connected to the ejector tube 130 after being discharged from the outlet end, or it can be any other flow pattern, as long as the gas can be distributed in multiple cavities.
[0131] In this embodiment, the ejector tube 130 is used to guide external gas to the main body 110, and the main body 110 is used to divert the gas to multiple burner caps. In this embodiment, multiple cavities are arranged in a nested manner and adjacent cavities are connected, so that multiple cavities are interconnected. Therefore, the user only needs to adjust the amount of gas entering the ejector tube 130 to simultaneously adjust the amount of gas in multiple cavities, thereby realizing the synchronous adjustment of multi-ring flames and improving the heating effect of the burner 1000.
[0132] Referring to Figures 9, 11 and 12, in some embodiments, the inlet of each cavity is positioned directly opposite the outlet end of the ejector tube 130.
[0133] In this embodiment, the inlet of each cavity is directly opposite the outlet of the ejector tube 130, so that the gas discharged from the outlet of the ejector tube can be directly diverted to multiple cavities, which further improves the uniformity of the gas quantity distributed in multiple cavities and further improves the heating effect of the burner 1000.
[0134] In some embodiments, the opposite sidewalls of the partition component 120 respectively participate in defining adjacent cavities, and the partition component 120 is provided with a connecting opening 123 connecting the adjacent cavities.
[0135] In this embodiment, the connection between adjacent cavities is simple, requiring only a connection opening 123 to be provided on the partition component 120, which simplifies the burner structure 100 and reduces the cost of the burner structure 100.
[0136] In some embodiments, a portion of the separator 120 is spaced apart from the outlet end of the ejector tube 130 to define a communication opening 123.
[0137] Through the above technical solution, the gas discharged from the outlet end of the ejector tube 130 can be directly diverted to the connecting opening 123, thereby enabling the gas discharged from the outlet end of the ejector tube 130 to be directly diverted to multiple chambers, improving the uniformity of the gas quantity distributed in multiple chambers, improving the heating effect of the burner 1000, and also simplifying the burner head structure 100 and reducing the cost of the burner head structure 100.
[0138] In some specific embodiments, the separator 120 is formed in a ring shape, and the plurality of cavities include a first cavity 112 and a second cavity 113, wherein the first cavity 112 is located inside the separator 120 and the second cavity 113 is located outside the separator 120.
[0139] In this embodiment, the burner head structure 100 is provided with only a first cavity 112 and a second cavity 113, which simplifies the burner head structure 100 and reduces the cost of the burner head structure 100.
[0140] In some specific embodiments, the separating component 120 includes a plurality of spaced-apart separating plates, with the aforementioned connecting opening 123 formed between two adjacent separating plates.
[0141] In this embodiment, the structure of the separator component 120 is simple, which further reduces the cost of the burner structure 100.
[0142] In some embodiments, the ejector tube 130 and the body 110 are integrally formed.
[0143] In this embodiment, the ejector tube 130 and the main body 110 are integrally formed, which means that the installation step of fixing the ejector tube 130 to the main body 110 is omitted, improving the production efficiency of the burner structure 100 and reducing the cost of the burner structure 100. Since no fasteners are needed to connect the ejector tube 130 and the main body 110, the material used in the burner structure 100 is reduced, further reducing the cost of the burner structure 100 and also reducing carbon emissions during the production process. Furthermore, the integrally formed ejector tube 130 and the main body 110 have no gaps, avoiding the risk of gas leakage from the gaps between the ejector tube 130 and the main body 110, thus improving the safety of the burner structure 100.
[0144] In some embodiments, a plurality of ejector tubes 130 are provided, and the plurality of ejector tubes 130 are spaced apart.
[0145] In this embodiment, the burner structure 100 is provided with multiple ejector tubes 130, which means that the gas can enter the gas receiving chamber 111 through multiple ejector tubes 130, thereby increasing the flow rate of the gas and improving the heating effect of the burner 1000.
[0146] In some application scenarios, the gas stove is equipped with multiple nozzles 500, each corresponding to a specific injector tube 130. Each nozzle 500 is directly opposite the inlet end of its corresponding injector tube 130, and all nozzles 500 are connected to the same gas pipeline. When the gas stove is operating, the gas in the gas pipeline is diverted to the multiple nozzles 500. Each nozzle 500 sprays gas towards its corresponding injector tube 130, and the gas in all injector tubes 130 enters the gas receiving chamber 111 and is then distributed to multiple chambers. In this embodiment, the user can adjust the opening of the gas pipeline to regulate the total amount of gas entering the gas receiving chamber 111, thereby adjusting the amount of gas in each chamber and achieving synchronous adjustment of the multi-ring flame.
[0147] In some embodiments, the partition component 120 is provided with a connecting opening 123 that connects adjacent cavities. Multiple connecting openings 123 are provided, and each of the multiple connecting openings 123 corresponds to a multiple ejector tube 130. The connecting opening 123 is located near the outlet end of the corresponding ejector tube 130.
[0148] Through the above technical solution, the gas discharged from each ejector tube 130 can be directly diverted to multiple chambers, which further improves the uniformity of gas distribution in each chamber and further improves the heating effect of the burner 1000.
[0149] In some embodiments, at least a portion of the ejector tubes 130 have their outlet openings facing the same direction.
[0150] Because multiple chambers are formed in a ring shape, and the openings of some ejector tubes 130 at their outlets face the same direction, the turbulence of the gas and air in the multiple chambers is increased, the uniformity of the gas-air mixture is improved, and the heating effect of the burner 1000 is enhanced.
[0151] In some specific embodiments, two ejector tubes 130 are provided, which are spaced apart and arranged in parallel, such that the openings of the outlet ends of the two ejector tubes 130 face the same direction.
[0152] In this embodiment, the burner head structure 100 has a simple structure, which reduces the cost of the burner head structure 100.
[0153] Referring to Figures 9, 10 and 11, in some embodiments, the body 110 is at least partially overlapped with the ejector tube 130 in the projection along the height direction of the body 110.
[0154] The above technical solution ensures the length of the ejector tube 130 while reducing the overall space occupied by the furnace head structure 100, which is conducive to the miniaturization of the furnace head structure 100.
[0155] In some specific embodiments, in the direction perpendicular to the height of the main body 110, the main body 110 includes a first burner head portion 114 and a second burner head portion 115 connected together. The first burner head portion 114 and the second burner head portion 115 together define a gas receiving cavity 111. The inner bottom wall of the second burner head portion 115 is higher than the inner bottom wall of the first burner head portion 114. The outlet end of the ejector tube 130 is located on the lower side of the second burner head portion 115 and communicates with the first burner head portion 114.
[0156] In this embodiment, the outlet end of the ejector tube 130 can be directly connected to the inner wall of the first burner head portion 114, instead of the outlet end of the ejector tube 130 extending into the gas containing cavity 111, which reduces the difficulty of mold opening of the burner head structure 100 and facilitates the integral molding of the burner head structure 100.
[0157] In some specific embodiments, the partition assembly 120 includes a first partition 121 and a second partition 122, wherein the first partition 121 is disposed on the inner bottom wall of the first burner portion 114, and the second partition 122 is disposed on the inner bottom wall of the second burner portion 115. The first partition 121 and the second partition 122 divide the gas containing chamber 111 into a first chamber 112 and a second chamber 113. The first chamber 112 is located inside the first partition 121 and the second partition 122, and the second chamber 113 is located outside the first partition 121 and the second partition 122. The gap between the first partition 121 and the second partition 122 forms a communicating opening 123.
[0158] In this embodiment, the burner head structure 100 has a simple structure, which reduces the cost of the burner head structure 100.
[0159] Referring to Figures 1, 2, and 9, in some embodiments, the top of the main body 110 is open, and the top of the main body 110 is suitable for connecting multiple burner caps. In some application scenarios, a gas distribution plate is provided between the main body 110 and the multiple burner caps, and the main body 110 is connected to the multiple burner caps through the gas distribution plate. The top of the main body 110 is connected to the gas distribution plate, and the gas distribution plate closes the opening at the top of the main body 110 to prevent gas leakage. The gas distribution plate is provided with multiple gas passages, and the multiple gas passages are connected to multiple cavities one-to-one. Each cavity is connected to the corresponding burner cap through the corresponding gas passage.
[0160] In some embodiments, the main body 110 is further provided with a third air passage 116, which extends through the main body 110 in the height direction. The gas receiving cavity 111 is spaced apart from the third air passage 116, and the third air passage 116 communicates with the space radially inner side of the central ring.
[0161] Through the above technical solution, the third air passage 116 is suitable for guiding the air at the bottom of the main body 110 to the inner flame cap, providing secondary air for the combustion of the flame, and improving the heating effect of the burner 1000.
[0162] In some specific embodiments, the gas containment cavity 111 is arranged around the third air passage 116.
[0163] When the burner 1000 is working, the outer ring flame can directly contact the outside air, while the inner ring flame has difficulty obtaining secondary air due to the obstruction of the outer ring flame. In this embodiment, the gas receiving cavity 111 is arranged around the third air channel 116, so that the third air channel 116 can provide secondary air for the inner ring flame, effectively improving the heating effect of the burner 1000.
[0164] This application also proposes another type of burner.
[0165] Referring to Figures 13, 14, and 15, a burner 1000 according to an embodiment of this application includes: a mounting member 700, a nozzle 500, a distribution plate assembly, and multiple burner caps. The mounting member 700 is adapted to be installed on an external fixing member and can directly or indirectly support other components in the burner 1000, ensuring the overall stability of the burner 1000. The nozzle 500 is disposed on the mounting member 700 and is adapted to communicate with an external gas pipeline, allowing gas to be ejected from the nozzle 500. The distribution plate assembly is disposed on the mounting member 700 and is used to distribute the gas ejected from the nozzle 500 to multiple burner caps. Each burner cap has a flame hole, and when the burner 1000 is operating, the gas passes through the flame hole and burns on the burner cap.
[0166] It should be understood that the mounting component 700 may also be used only to support the nozzle 500. Other components in the burner 1000 may be directly or indirectly fixed to external fasteners. For example, in some application scenarios, the mounting component 700 is installed on the cooktop of the gas stove, the nozzle 500 is installed on the mounting component 700, the diverter assembly is also installed on the cooktop of the gas stove, and multiple burner caps are installed on the diverter assembly. Other installation situations are also possible, and this application does not limit them.
[0167] Specifically, the distribution plate assembly includes a gas distribution plate 200 and a guide assembly 600. The gas distribution plate 200 is the same as the gas distribution plate 200 described in the above technical solution. The guide assembly 600 is disposed on the gas distribution plate 200 and communicates with the first gas passage 211 and the second gas passage 225 respectively. At least a portion of the guide assembly 600 extends vertically. The nozzle 500 is located below the guide assembly 600 and is directly opposite to it. Multiple burner caps are respectively disposed at the gas outlet ends of the first gas passage 211 and the second gas passage 225.
[0168] When the burner 1000 is working, the nozzle 500 sprays gas toward the guide assembly 600, and carries nearby air into the guide assembly 600. The gas mixture of gas and air flows upward in the guide assembly 600 and is then divided into the first gas passage 211 and the second gas passage 225, and then enters multiple burner caps. The gas burns on the corresponding burner cap after passing through the burner holes.
[0169] Each burner cap can form at least one cluster of flames or one ring of flames. The burner 1000 in this embodiment of the application is provided with multiple burner caps, so that multiple clusters of flames or multiple rings of flames can be formed on the burner 1000, which increases the heating area of the heated pot and improves the heating efficiency of the burner 1000.
[0170] Furthermore, in this embodiment of the application, the amount of gas entering the guide assembly 600 can be controlled by controlling the amount of gas passing through the nozzle 500, thereby controlling the amount of gas in multiple burner caps. In other words, the user can adjust the amount of gas passing through the nozzle 500 to achieve synchronous adjustment of the flames on multiple burner caps, improve the uniformity of heating of the heated pot body, and improve the heating effect of the burner 1000.
[0171] It should be noted that the specific way to adjust the amount of gas passing through nozzle 500 is to adjust the opening of the valve on the external gas pipeline.
[0172] At least a portion of the guide assembly 600 extends vertically, allowing the gas mixture of fuel gas and air to flow directly upwards. Since the density of fuel gas is typically lower than that of air, the vertical extension of at least a portion of the guide assembly 600 conforms to the flow characteristics of fuel gas, thus improving the efficiency of fuel gas supply. Furthermore, in this embodiment, the guide assembly 600 has a simple structure, is easy to manufacture, and reduces the cost of the burner 1000.
[0173] According to the embodiments of this application, the burner 1000 can form multiple clusters or rings of flame, increasing the heating area of the heated pot and improving the heating efficiency of the burner 1000. The user can adjust the amount of gas passing through the nozzle 500 to achieve synchronous adjustment of the flames on multiple burner caps, improving the uniformity of heating of the heated pot and enhancing the heating effect of the burner 1000. At least a portion of the guide assembly 600 extends vertically, conforming to the flow characteristics of the gas and improving the gas supply efficiency. The guide assembly 600 has a simple structure, is easy to manufacture, and reduces the cost of the burner 1000.
[0174] In some embodiments, the mounting member 700 is provided with a mounting cavity 710, the nozzle 500 is located in the mounting cavity 710, the top of the mounting member 700 is provided with a first opening 720 communicating with the mounting cavity 710, and at least a portion of the guide assembly 600 is located in the mounting cavity 710.

[0189] In some specific embodiments, the gas inlet end of the gas pipeline 740 protrudes from the outer peripheral wall of the mounting component 700, further improving the convenience of connecting the gas pipeline 740 to the external gas pipeline.
[0190] In some embodiments, the guide assembly 600 includes a mounting plate 610 and a vertically extending guide tube 620. The mounting plate 610 is mounted below the gas distributor 200, and an air intake passage is defined between the mounting plate 610 and the gas distributor 200. The air intake passage is connected to a first gas passage 211 and a second gas passage 225, respectively.

[0191] When the burner 1000 is working, the external gas flows to the nozzle 500 through the gas supply pipe 740, and then is sprayed into the guide pipe 620 through the nozzle 500. The gas sprayed into the guide pipe 620 carries some air into the guide pipe 620. The gas mixture of gas and air flows upward in the guide pipe 620 to the air intake channel, and then is split into the first gas channel 211 and the second gas channel 225, and then enters multiple burner caps. After passing through the burner holes, the gas burns on the corresponding burner caps.
[0192] In this embodiment, the guide component 600 has a simple structure, which reduces the cost of the burner 1000.
[0193] In some embodiments, at least the surface of the mounting plate 610 facing the air distribution plate 200 extends downward in the direction toward the guide pipe 620.
[0194] Through the above technical solution, the surface of the mounting plate 610 facing at least the gas distribution plate 200 is formed as a guiding surface for guiding the flow of gas, which facilitates the diversion of gas into the first gas channel 211 and the second gas channel 225, thereby improving the flow efficiency of gas.

[0204] It should be understood that in other embodiments, the mounting plate 610 and the edge of the first opening 720 may also be snap-fitted together, and this application does not limit this.
[0205] In other embodiments, the air distribution plate 200 may overlap and support the portion of the mounting member 700 that forms the first opening 720, as long as the mounting member 700 can support the air distribution plate assembly.
[0206] Referring to FIG15, in some embodiments, the air inlet end of the gas distributor 200 is sleeved over the portion of the mounting plate 610 away from the guide pipe 620, so that the gas in the mounting plate 610 can completely enter the gas distributor 200, reducing the risk of gas leakage between the gas distributor 200 and the mounting plate 610.
[0207] In some specific embodiments, the inner diameter of the air inlet end of the gas distributor 200 is adapted to the outer diameter of the portion of the mounting plate 610 away from the guide pipe 620, which improves the tightness of the fit between the gas distributor 200 and the mounting plate 610 and further reduces the risk of gas leakage between the gas distributor 200 and the mounting plate 610.
[0208] In some further embodiments, the mounting plate 610 is also provided with a first support portion 611, which supports the air intake end of the air distribution plate 200, further improving the stability of the air distribution plate 200.
[0209] Referring to Figures 3, 4, and 5, in some embodiments, the gas distribution plate 200 includes: a first portion 210 and a second portion 220. The first portion 210 defines a first gas passage 211. The second portion 220 includes an inner ring portion 221, an outer ring portion 222, and a first connecting portion 223. The inner ring portion 221 is connected to the first portion 210.

The first connecting portion 223 is connected to both the inner ring portion 221 and the outer ring portion 222. A second gas passage 225 is defined within the first connecting portion 223. The second gas passage 225 has a first air outlet 2251 located in the outer ring portion 222 and a first air inlet 2252 located in the inner ring portion 221. The first portion 210 and the second portion 220 are integrally formed.
[0210] Referring to Figures 13, 14, and 3, in some specific application scenarios of this application, multiple burners include an inner burner 300 and an outer burner 400. The inner burner 300 is installed in the first part 210 and is connected to the first gas passage 211. The first gas passage 211 can guide the gas to the inner burner 300, and the gas is suitable for combustion at the inner burner 300 to form an inner ring flame. The outer burner 400 is installed in the outer ring part 222 and is connected to the first gas outlet 2251 of the outer ring part 222. The gas can enter the second gas passage 225 through the first gas inlet 2252 of the inner ring part 221, and then flow to the outer burner 400 through the first gas outlet 2251. The gas is suitable for combustion at the outer burner 400 to form an outer ring flame.
[0211] In this embodiment, the first portion 210 defines a first gas passage 211, and the second portion 220 defines a second gas passage 225. The first portion 210 and the second portion 220 are integrally molded, simplifying the structure of the gas distribution plate 200 and reducing its cost. Furthermore, compared to gas distribution plates 200 in related technologies that are assembled from multiple components, the gas distribution plate 200 in this embodiment is an integrally molded part, avoiding installation gaps at component connections, reducing the risk of gas leakage from the gas distribution plate 200, and improving the safety of the burner 1000.
[0212] Referring to Figures 3, 5, and 6, the first part 210 is located at the center of the entire gas distribution plate 200, making it suitable for connection with the inner burner cap 300. The inner ring part 221 is connected to the first part 210, so that the first air inlet 2252 is located near the first gas passage 211, which facilitates the diversion of external gas. The simplified structure of the gas distribution plate 200 facilitates the installation between the gas distribution plate 200 and the mounting plate.
[0213] When the burner is working, the external gas flows to the nozzle through the gas delivery channel, and then is sprayed into the guide tube through the nozzle. The gas sprayed into the guide tube carries some air with it. The gas mixture of gas and air flows upward in the guide tube to the intake channel. Then, the gas is split at the connection between the inner ring part 221 and the first part 210. One part of the gas enters the first gas passage 211 and then flows to the inner burner cap 300. The other part of the gas enters the first air inlet 2252 and then flows to the outer burner cap 400 through the second gas passage 225 and the first air outlet 2251.
[0214] It should be noted that the outer ring portion 222 being at least partially located outside the inner ring portion 221 means that, in a projection plane perpendicular to the thickness direction of the outer ring portion 222, the inner ring portion 221 is formed into a ring structure, and the outer ring portion 222 is also formed into a ring structure, with at least a portion of the outer ring portion 222 located outside the inner ring portion 221. This allows the outer ring portion 222 to be located outside the first portion 210, meaning that the outer flame cap 400 connected to the outer ring portion 222 can be located outside the inner flame cap 300. This allows the burner 1000 to form a multi-ring flame, improving the heating effect of the burner 1000.
[0215] It should also be noted that the inner ring portion 221 and the outer ring portion 222 can be a circular ring structure, or a rectangular ring structure, a regular octagonal ring structure, or a ring structure of other shapes. This application does not limit this.
[0216] Furthermore, in this embodiment, the outer ring portion 222 and the inner ring portion 221 are spaced apart to define the first air passage 224, so that outside air can enter between the outer ring portion 222 and the first portion 210 through the first air passage 224, thereby allowing outside air to enter between the outer burner cap 400 and the inner burner cap 300, providing air for the flame on the outer burner cap 400 and / or the inner burner cap 300, and improving the combustion efficiency of the burner 1000.
[0217] In this embodiment, the gas distribution plate 200 is a single molded part, which simplifies the structure of the gas distribution plate 200, reduces the cost of the gas distribution plate 200, avoids installation gaps at the connection of parts, reduces the risk of gas leakage from the gas distribution plate 200, and improves the safety of the burner 1000. The inner ring portion 221 is connected to the first portion 210, so that the first air inlet 2252 is located near the first gas passage 211, which facilitates the diversion of external gas. The simplified structure of the gas distribution plate 200 facilitates the installation of the gas distribution plate 200. A first air passage 224 is provided between the outer ring portion 222 and the inner ring portion 221. The first air passage 224 can introduce outside air between the outer burner cap 400 and the inner burner cap 300, providing air for the flame on the outer burner cap 400 and / or the inner burner cap 300, thereby improving the combustion efficiency of the burner 1000.
[0218] Referring to Figures 13, 14 and 15, in some embodiments, at least one burner cap has a flame hole formed as an elongated hole extending downwards and obliquely toward the nozzle 500, so that the flame on the burner cap is formed into a cohesive flame, thereby improving the heating effect of the burner 1000.

[0220] When the burner 1000 is working, the gas in the first gas passage 211 burns on the inner flame cap 300 after passing through the first flame hole 310. Because each first flame hole 310 extends at an angle toward the center of the inner flame cap 300, the flame on the inner flame cap 300 is formed into a cohesive flame, which improves the heating effect of the burner 1000.
[0221] It should be understood that the flame holes on the inner flame cover 300 can also be set upwards or in a direction away from the center of the inner flame cover 300, and this application does not limit this.

[0223] When the burner 1000 is operating, a portion of the gas in the first gas passage 211 passes through the first flame hole 310 and burns radially inward on the inner burner cap 300, forming a ring flame. Another portion of the gas in the first gas passage 211 passes through the second flame hole and burns radially outward on the inner burner cap 300, forming another ring flame. In other words, two ring flames can be formed on the inner burner cap 300. It should be understood that the flame holes on the inner burner cap 300 can also be arranged in other ways to allow multiple ring flames to be formed on the inner burner cap 300; this application does not limit this arrangement.
[0224] In some embodiments, the inner burner cap 300 is fitted over the gas outlet end of the first portion 210, so that the gas in the first gas passage 211 can completely enter the inner burner cap 300, reducing the risk of gas leakage between the first portion 210 and the inner burner cap 300.

[0226] In some further embodiments, the first part 210 is also provided with a second support 216, which supports the inner flame cover 300 and further improves the stability of the inner flame cover 300.

Because each third flame hole 410 extends at an angle toward the center of the outer flame cap 400, the flame on the outer flame cap 400 is formed into a cohesive flame, which improves the heating effect of the burner 1000.
[0229] It should be understood that the flame holes on the outer flame cover 400 can also be set facing upwards or in a direction away from the center of the outer flame cover 400, and this application does not limit this.
[0230] In other embodiments, a plurality of third flame holes 410 are provided on the radially inner side of the outer flame cover 400, and the plurality of third flame holes 410 are distributed at intervals along the circumference of the outer flame cover 400.

Another portion of the gas in the second gas passage 225 passes through the fourth flame hole and burns radially outward on the outer flame cap 400, forming another ring flame. In other words, two ring flames can be formed on the outer flame cap 400. It should be understood that the flame holes on the outer flame cap 400 can also be arranged in other ways to allow multiple ring flames to be formed on the outer flame cap 400; this application does not limit this arrangement.
[0232] In some embodiments, the outer burner cap 400 is fitted over the outer ring portion 222, allowing the gas in the outer ring portion 222 to fully enter the outer burner cap 400, thereby reducing the risk of gas leakage between the outer ring portion 222 and the outer burner cap 400.
[0233] In some specific embodiments, the inner diameter of the air inlet end of the outer burner cap 400 is adapted to the outer diameter of the outer ring portion 222, which improves the tightness of the fit between the outer burner cap 400 and the outer ring portion 222, and further reduces the risk of gas leakage between the outer burner cap 400 and the outer ring portion 222.
[0234] In some further embodiments, the outer ring portion 222 is also provided with a third support portion 226, which supports the outer flame cap 400 and further improves the stability of the outer flame cap 400.
