Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The following is for reference. Figures 1-6 Describes the burner head structure 100 according to an embodiment of the present utility model.

[0036] It should be noted that the burner structure 100 is part of the burner 200 of the gas stove, as shown in the reference. Figure 1 , Figure 2 and Figure 3 The burner 200 also includes a flame cap 210, on which flame holes 211 are provided. The burner head structure 100 is used to guide the gas to the flame cap 210. After the gas is discharged from the flame holes 211, it burns to form a flame.

[0037] Reference Figure 2 , Figure 3 and Figure 4 According to an embodiment of the present invention, the burner head structure 100 includes: a main body 110, a partition component 120, and an ejector tube 130. The main body 110 has a gas receiving cavity 111. The partition component 120 is disposed within the main body 110 and located within the gas receiving cavity 111. The partition component 120 is used to divide 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 210. The ejector tube 130 is disposed within the main body 110 and communicates with the multiple cavities respectively.

[0038] It should be noted that the nested multiple cavities refer to multiple cavities being a first cavity 112, a second cavity 113, ..., the Nth cavity, with the Nth cavity encasing the (N-1)th cavity, where N can be an integer of 2 or greater. For example, in some embodiments, the partition assembly 120 divides the gas containing cavity 111 into two cavities, namely the first cavity 112 and the second cavity 113, with the second cavity 113 encasing the first cavity 112. In other embodiments, the partition assembly 120 divides the gas containing cavity 111 into three cavities, namely the first cavity 112, the second cavity 113, and the third cavity, with the second cavity 113 encasing the first cavity 112 and the third cavity encasing the second cavity 113.

[0039] In some application scenarios, the gas stove nozzle 220 is positioned directly opposite the inlet end of the injector tube 130. Multiple cavities are connected to multiple burner caps 210 respectively, with each cavity corresponding to one burner cap 210. Each burner cap 210 is provided with a flame hole 211. Because the multiple cavities are nested sequentially, the multiple burner caps 210 are also set to be nested sequentially.

[0040] When the gas stove is working, the nozzle 220 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 210 and is discharged from the burner hole 211 of the burner cap 210. After the gas is discharged from the burner hole 211, it burns to form a flame, and multiple ring flames are formed on the sequentially nested burner caps 210.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] According to the burner head structure 100 of this utility model embodiment, the injector tube 130 is used to guide the external gas to the main body 110, and the main body 110 is used to divert the gas to multiple burner caps 210. In this utility model 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 injector 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 200.

[0045] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments, the inlet of each cavity is positioned directly opposite the outlet of the ejector tube 130.

[0046] In this embodiment of the invention, the inlet of each cavity is directly opposite the outlet end of the ejector tube 130, so that the gas discharged from the outlet end 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 200.

[0047] 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.

[0048] In this embodiment of the utility model, 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.

[0049] 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.

[0050] 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 200, and also simplifying the burner head structure 100 and reducing the cost of the burner head structure 100.

[0051] 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.

[0052] In this embodiment of the invention, 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 its cost.

[0053] 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.

[0054] In this embodiment of the invention, the structure of the separator component 120 is simple, which further reduces the cost of the burner structure 100.

[0055] In some embodiments, the ejector tube 130 and the body 110 are integrally formed.

[0056] In this embodiment of the invention, 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, thereby improving the production efficiency of the burner structure 100 and reducing its cost. 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 lowering its cost and reducing carbon emissions during production. 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 them and improving the safety of the burner structure 100.

[0057] In some embodiments, a plurality of ejector tubes 130 are provided, and the plurality of ejector tubes 130 are spaced apart.

[0058] In this embodiment of the invention, 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 200.

[0059] In some application scenarios, the gas stove is equipped with multiple nozzles 220, each corresponding to a specific injector tube 130. Each nozzle 220 is directly opposite the inlet end of its corresponding injector tube 130, and all nozzles 220 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 220. Each nozzle 220 sprays gas towards its corresponding injector tube 130, and the gas in all the 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.

[0060] 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.

[0061] 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 200.

[0062] In some embodiments, at least a portion of the ejector tubes 130 have their outlet openings facing the same direction.

[0063] 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 200 is enhanced.

[0064] 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.

[0065] In this embodiment of the utility model, the structure of the burner head 100 is simple, which reduces the cost of the burner head structure 100.

[0066] Reference Figure 3 , Figure 4 and Figure 5In some embodiments, in the projection of the body 110 in the height direction, the body 110 at least partially overlaps with the ejector tube 130.

[0067] 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.

[0068] In some specific embodiments, in a direction perpendicular to the height of the body 110, the body 110 includes a first part 114 and a second part 115 connected together, the first part 114 and the second part 115 together defining a gas receiving cavity 111, the inner bottom wall of the second part 115 is higher than the inner bottom wall of the first part 114, and the outlet end of the ejector tube 130 is located below the second part 115 and communicates with the first part 114.

[0069] In this embodiment of the utility model, the outlet end of the ejector tube 130 can be directly connected to the inner wall of the first part 114, instead of the outlet end of the ejector tube 130 extending into the interior of 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.

[0070] 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 portion 114, and the second partition 122 is disposed on the inner bottom wall of the second portion 115. The first partition 121 and the second partition 122 divide the gas containing chamber 111 into a first cavity 112 and a second cavity 113. The first cavity 112 is located inside the first partition 121 and the second partition 122, and the second cavity 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.

[0071] In this embodiment of the utility model, the structure of the burner head 100 is simple, which reduces the cost of the burner head structure 100.

[0072] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the top of the main body 110 is open, and the top of the main body 110 is adapted to connect multiple burner caps 210. In some application scenarios, a gas distribution plate 230 is provided between the main body 110 and the multiple burner caps 210, and the main body 110 is connected to the multiple burner caps 210 through the gas distribution plate 230. The top of the main body 110 is connected to the gas distribution plate 230, and the gas distribution plate 230 closes the opening at the top of the main body 110 to prevent gas leakage. The gas distribution plate 230 is provided with multiple gas passages, and the multiple gas passages are connected to multiple cavities one by one. Each cavity is connected to the corresponding burner cap 210 through the corresponding gas passage.

[0073] In some embodiments, the main body 110 is further provided with an air passage 116, which extends through the main body 110 in the height direction, and the gas receiving cavity 111 is spaced apart from the air passage 116.

[0074] Through the above technical solution, the air channel 116 is suitable for guiding the air at the bottom of the main body 110 to the burner cap 210, providing secondary air for the combustion of the flame, and improving the heating effect of the burner 200.

[0075] In some specific embodiments, the gas containment cavity 111 is arranged around the air passage 116.

[0076] When the burner 200 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 of the present invention, the gas receiving cavity 111 is arranged around the air channel 116, so that the air channel 116 can provide secondary air for the inner ring flame, which effectively improves the heating effect of the burner 200.

[0077] Other configurations of the burner head structure 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0078] The burner 200 according to an embodiment of the present invention includes: the burner head structure 100 and a plurality of burner caps 210 as described in the above technical solution, wherein the plurality of burner caps 210 are respectively connected to a plurality of cavities.

[0079] According to the burner 200 of this utility model embodiment, in its burner head structure 100, the injector tube 130 is used to guide the external gas to the main body 110, and the main body 110 is used to divert the gas to multiple burner caps 210. Multiple cavities in the main body 110 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 injector 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 200.
