[0003] Currently, gas stoves generally consist of a burner assembly, a burner head, and a high-powered nozzle assembly. The burner assembly is mounted on the burner head, and the high-powered nozzle assembly passes through the burner head with its gas outlet extending into the burner assembly. When the gas stove is in high-powered mode, the high-powered nozzle assembly supplies a separate gas supply to the burner assembly to achieve the high-powered stir-fry function.

[0004] However, when the gas stove is turned on the high-heat mode, the primary air intake hole of the high-heat nozzle assembly may be blocked by the burner head, resulting in poor primary air supply and thus easily affecting the combustion performance of the gas stove. Utility Model Content

[0065] A gas stove is a kitchen appliance that uses gaseous fuels such as liquefied petroleum gas (LPG), manufactured gas, and natural gas for direct-fire heating. Specifically, when a gas stove is working, gas enters the stove through the gas inlet pipe, and after being regulated by the gas valve, it enters the burner head. For example, the user adjusts the gas valve by turning a knob, while simultaneously mixing it with some air. This mixture of gas is ejected from the burner holes and ignited by the ignition device to form a flame. This flame is used to heat the cookware placed on the pot support.

[0066] In related technologies, gas stoves generally include a burner assembly, a burner head, and a high-heat nozzle assembly. The burner assembly is mounted on the burner head, and the high-heat nozzle assembly passes through the burner head with its gas outlet extending into the burner assembly. When the gas stove is in high-heat mode, the high-heat nozzle assembly supplies a separate gas supply to the burner assembly to achieve the high-heat cooking function.

[0067] However, when the gas stove is turned on the high-heat mode, the primary air intake hole of the high-heat nozzle assembly may be blocked by the burner head, resulting in poor primary air supply and thus easily affecting the combustion performance of the gas stove.

[0068] To address the aforementioned problems, this application provides a novel combustion device and gas stove. The combustion device includes a burner head and a high-powered nozzle assembly. The high-powered nozzle assembly includes a base and a first connecting pipe mounted on the base. One end of the first connecting pipe, away from the base, passes through the burner head. An air inlet communicating with the first connecting pipe is provided on the base. A clearance space is provided on the burner head at a position corresponding to the base, allowing the air inlet to be exposed outside the burner head. This application avoids the air inlet of the high-powered nozzle assembly being blocked by the burner head, thereby ensuring primary air supply capacity and thus ensuring the combustion performance of the gas stove.

[0069] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0070] The following is a detailed description of the combustion device and the specific structure of the gas stove equipped with the combustion device, with reference to the accompanying drawings.

[0071] Figure 1 This is a schematic diagram of a gas stove provided in an embodiment of this application. Figure 2 This is a schematic diagram of a combustion device in a gas stove provided in an embodiment of this application. Figure 3 This is another structural schematic diagram of the combustion device in a gas stove provided in an embodiment of this application. Figure 4 This is a schematic diagram of a stir-fry nozzle assembly in a combustion device provided in an embodiment of this application. Figure 5 This is another structural schematic diagram of the stir-fry nozzle assembly in the combustion device provided in the embodiments of this application.

[0072] Please refer to Figure 1 and Figure 2 As shown, this application embodiment provides a combustion device 100, which may include a burner head 110 and a stir-fry nozzle assembly 130. Specifically, in this application embodiment, the stir-fry nozzle assembly 130 may include a base 131 and a first connecting pipe 132, wherein the first connecting pipe 132 may be installed on the base 131, and the end of the first connecting pipe 132 away from the base 131 may pass through the burner head 110.

[0073] In the embodiments of this application, see Figures 2 to 5 As shown, a make-up air port 1314 communicating with the first connecting pipe 132 can be provided on the base 131. Primary air can be introduced into the first connecting pipe 132 through the make-up air port 1314. Specifically, the gas flowing in the first connecting pipe 132 can carry more primary air into the first connecting pipe 132 through the make-up air port 1314.

[0074] like Figure 3As shown in this embodiment, a clearance space 111 can be provided on the burner head 110 at a position corresponding to the base 131, so that the air supply port 1314 can be exposed outside the burner head 110. In this way, the air supply port 1314 of the stir-fry nozzle assembly 130 can be prevented from being blocked by the burner head 110, thereby ensuring that the air supply port 1314 can sufficiently entice primary air, thus ensuring the primary air supply capacity, and thus ensuring the combustion performance of the gas stove, thereby ensuring the combustion efficiency of the gas stove.

[0075] Understandably, see Figure 4 As shown in the embodiment of this application, the base 131 may have a gas passage 131a, which may be connected to the first connecting pipe 132. Moreover, the air supply port 1314 may be located at one end of the base 131 near the first connecting pipe 132.

[0076] Figure 6 This is another structural schematic diagram of the combustion device 100 in the gas stove provided in the embodiments of this application. Figure 7 for Figure 6 A magnified structural diagram at point A.

[0077] Reference Figure 6 and Figure 7 As shown in the embodiments of this application, the combustion device 100 may further include: a burner assembly 120, wherein the burner assembly 120 may have a first mixing chamber 1201 and a first flame port 1221, wherein the first flame port 1221 may be connected to the first mixing chamber 1201.

[0078] It is understood that, in some embodiments, the end of the first connecting pipe 132 facing away from the base 131 can extend into the first mixing chamber 1201 and communicate with the first flame hole 1221. In this way, the gas flowing in the first connecting pipe 132 can drive more primary air into the first connecting pipe 132 through the air supply port 1314, thereby increasing the amount of primary air in the first mixing chamber 1201 connected to the first connecting pipe 132.

[0079] In this embodiment of the application, the first connecting pipe 132 may include a first connecting pipe body 1321 and a first sleeve 1322, wherein one end of the first connecting pipe body 1321 may be connected to the base 131, and the other end of the first connecting pipe body 1321 may be connected to one end of the first sleeve 1322.

[0080] In addition, in this embodiment, the other end of the first sleeve 1322 can extend into the first mixing chamber 1201 and communicate with the first flame hole 1221. In this way, the first sleeve 1322 can divide the first mixing chamber 1201 inside the burner assembly 120, reduce the volume of the first mixing chamber 1201, and thus avoid or reduce the risk of backfire in the combustion device 100 in the high-heat mode, thereby avoiding or reducing unnecessary safety hazards of the gas stove.

[0081] Figure 8 This is another structural schematic diagram of the combustion device 100 in the gas stove provided in the embodiments of this application.

[0082] like Figure 8 As shown in the embodiment of this application, the inner diameter of the first sleeve 1322 can be larger than the inner diameter of the first connecting pipe body 1321. By designing the inner diameter of the first sleeve 1322 to be larger than the inner diameter of the first connecting pipe body 1321, the diameter of the channel in the first connecting pipe 132 can be increased, the resistance of the gas in the channel can be reduced, and the ejection capability can be improved, thereby ensuring sufficient primary air can be replenished to ensure stable combustion of the gas.

[0083] like Figure 4 and Figure 5 As shown in the embodiment of this application, the base 131 may include a second connecting pipe body 1311, a second sleeve 1312 and a connector 1313, wherein one end of the second connecting pipe body 1311 may be connected to the second sleeve 1312, and the other end of the second connecting pipe body 1311 may be connected to the first connecting pipe body 1321 through the connector 1313.

[0084] In some embodiments, such as Figure 4 and Figure 5 As shown, the air supply vent 1314 can be installed on the connector 1313.

[0085] In addition, in this embodiment, there can be multiple air supply ports 1314, which can be evenly spaced on the outer peripheral wall of the connector 1313. In this way, with multiple air supply ports 1314 evenly spaced around the outer peripheral wall of the connector 1313, the gas required for stir-frying can flow more evenly through the air supply ports 1314 into the stir-frying nozzle assembly 130 as it flows within the assembly.

[0086] It should be noted that, in one possible implementation, the second connecting pipe body 1311 is perpendicular to the first connecting pipe body 1321. This can relatively reduce the overall design space of the stir-fry nozzle assembly 130 in the combustion device 100.

[0087] In the embodiments of this application, such as Figure 2As shown, the burner assembly 120 may include a flame spreader 121, an inner ring flame cap 122, and an outer ring flame cap 123. The inner ring flame cap 122 and the outer ring flame cap 123 may be mounted on the flame spreader 121. The outer ring flame cap 123 has an outer ring cavity 1231 surrounding the inner ring flame cap 122. The inner ring flame cap 122 has a first flame hole 1221. The first flame hole 1221 and the flame spreader 121 may define a first mixing chamber 1201.

[0088] In this embodiment of the application, the first connecting pipe 132 may be disposed through the fire distributor 121.

[0089] Continue to refer to Figure 2 As shown in the embodiment of this application, the combustion device 100 may further include a bracket 140, wherein the stir-fry nozzle assembly 130 may be fixed to the burner head 110 through the bracket 140.

[0090] Specifically, in the embodiments of this application, the bracket 140 may include an installation part 141 and a clamping part 142, wherein the installation part 141 may be fixedly connected to the burner head 110, and the clamping part 142 may be used to clamp the first connecting pipe body 1321.

[0091] The combustion device 100 provided in this application embodiment has an air supply port 1314 on the base 131 of the stir-fry nozzle assembly 130, and the air supply port 1314 is connected to the first connecting pipe 132. By providing an avoidance space 111 at the position corresponding to the base 131 on the burner head 110, the air supply port 1314 is exposed outside the burner head 110, which can prevent the air supply port 1314 of the stir-fry nozzle assembly 130 from being blocked by the burner head 110. In this way, it can be ensured that the air supply port 1314 can inject enough primary air, thereby ensuring the primary air supply capacity, and thus ensuring the combustion performance of the gas stove, thereby ensuring the combustion efficiency of the gas stove.

[0092] like Figure 1 As shown in the figure, this application embodiment also provides a gas stove 200. Specifically, in this application embodiment, the gas stove 200 may include a gas valve 210, a high-heat gas passage 221 and the above-mentioned combustion device 100, with the two ends of the high-heat gas passage 221 connected to the base 131 of the combustion device 100 and the gas valve 210, respectively.

[0093] It is understood that, in the embodiments of this application, such as Figure 2 As shown, the combustion device 100 may include a stir-fry nozzle assembly 130, which may be connected to the stir-fry gas passage 221.

[0094] In this embodiment, the gas stove 200 may further include a conventional flame gas passage 222, with both ends of the conventional flame gas passage connected to the base 131 of the combustion device 100 and the gas valve 210, respectively. In this case, the combustion device 100 may also include a conventional nozzle assembly 150, wherein the conventional flame gas passage 222 may be connected to the conventional nozzle assembly 150.

[0095] The gas stove 200 provided in this application embodiment may include at least a combustion device 100. In the combustion device 100, a make-up air port 1314 is provided on the base 131 of the stir-fry nozzle assembly 130, and the make-up air port 1314 is connected to the first connecting pipe 132. By providing an avoidance space 111 at a position on the burner head 110 corresponding to the base 131, the make-up air port 1314 is exposed outside the burner head 110, which can prevent the make-up air port 1314 of the stir-fry nozzle assembly 130 from being blocked by the burner head 110. In this way, it can be ensured that the make-up air port 1314 can draw enough primary air, thereby ensuring the primary air supply capacity, and thus ensuring the combustion performance of the gas stove 200, thereby ensuring the combustion efficiency of the gas stove 200.
