Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0033] Referring to Figures 1-8 , the burner head applied to the outdoor stove is one of a hot pot stove, a gas stove, a wok stove or a sand pot stove, and the burner head comprises a burner base 1, an infrared combustion structure and an open fire combustion structure. In the embodiment, the burner base 1 comprises a center disc 18, an annular disc 19, a first ejector pipe 15 and a second ejector pipe 16. The annular disc 19 is located at the periphery of the center disc 18. The first ejector pipe 15 is arranged at the bottom of the center disc 18. The second ejector pipe 16 is arranged at the bottom of the annular disc 19. The first ejector pipe 15 and the second ejector pipe 16 are arranged side by side in the horizontal direction. The burner base 1 is provided with a first gas mixing chamber 11 and a second gas mixing chamber 12. The first gas mixing chamber 11 is arranged in the center disc 18. The second gas mixing chamber 12 is arranged in the annular disc 19. The first ejector pipe 15 is in communication with the first gas mixing chamber 11. The second ejector pipe 16 is in communication with the second gas mixing chamber 12. The top of the first gas mixing chamber 11 is open and arranged in the middle of the burner base 1. The second gas mixing chamber 12 is annular and arranged around the periphery of the first gas mixing chamber 11. The infrared combustion structure comprises an infrared radiation type ceramic plate 2, which is embedded in the first gas mixing chamber 11 through the top opening of the first gas mixing chamber 11 and is in communication with the first gas mixing chamber 11 and located in the middle of the burner base 1. When the burner head works, the gas burns in the first gas mixing chamber 11 and heats the object through the infrared radiation of the infrared radiation type ceramic plate 2. The open fire combustion structure comprises an open fire hole 3, which is arranged at the top of the open fire combustion structure, is in communication with the second gas mixing chamber 12 and is located at the periphery of the infrared combustion structure. When the burner head works, the gas is sprayed out from the second gas mixing chamber 12 to burn through the open fire combustion structure and heats the object through the open fire. Since the gas burns in the first gas mixing chamber 11 and generates a flame, when the burner head works outdoors, the flame generated by the infrared combustion structure is not affected by the wind during use, which can avoid being accidentally scattered or blown out, improves the wind resistance of the burner head, ensures the heating efficiency of the burner head outdoors, strengthens the outdoor practicability of the burner head and improves the use experience of people.

[0034] The burner head adopting the above technical scheme can re-ignite the open fire combustion structure when the flame generated by the open fire combustion structure is accidentally blown out, so that the open fire combustion structure recovers burning in time, and the wind resistance of the burner head is further improved.

[0035] The burner head adopting the above technical scheme reduces the situation that the gas leaks due to the flame being blown out, and improves the use safety of the burner head.

[0036] Further, in the embodiment, the top of the second mixing cavity 12 is closed, and the number of the open fire holes 3 is preferably ninety and evenly arranged on the top surface of the second mixing cavity 12, so that when the burner works, the flames generated by the open fire burning structure are more evenly distributed. The vertical section of the open fire hole 3 is conical, and the size gradually decreases from the second mixing cavity 12 to the external environment, which increases the speed of the gas flowing to the external environment, makes the gas further contact with the air in the external environment, and makes the gas burn more fully. Since the speed of the gas flowing to the external environment is increased, the gas content in the external environment is increased and the flame is maintained, which further improves the wind resistance of the burner. Those skilled in the art can understand this.

[0037] Alternatively, the top of the second mixing cavity 12 is open, and the burner further comprises a fire cover, which is covered on the top opening of the second mixing cavity 12.

Those skilled in the art can understand this.

[0039] Alternatively, in the embodiment, the burner further comprises an ignition component 4 and an extinguishing protection component 5, and the furnace seat 1 is provided with two fixed supports 17. Specifically, the ignition component 4 is preferably an ignition needle, and the extinguishing protection component 5 is preferably a thermocouple. The two fixed supports 17 are fixed in the gap between the infrared combustion structure and the open fire combustion structure and are oppositely arranged on both sides of the first mixing cavity 11. The ignition component 4 and the extinguishing protection component 5 are respectively mounted on the two fixed supports 17 by a fastening structure, so as to realize that the ignition component 4 is mounted on the furnace seat 1 and ignites the infrared combustion structure and the open fire combustion structure respectively, and the extinguishing protection component 5 is mounted on the furnace seat 1 and monitors the combustion state of the infrared combustion structure and the open fire combustion structure respectively. Those skilled in the art can understand this.

[0040] Further, in the embodiment, the vertical projection shape of the side wall of the first mixing cavity 11 is preferably circular. When the gap between the infrared combustion structure and the open flame combustion structure is smaller than the diameter of the ignition component 4, an avoiding portion 110 can be arranged on the side wall of the first mixing cavity 11, the avoiding portion 110 is recessed towards the center of the burner head and is arranged corresponding to the ignition component 4, so that the first mixing cavity 11 can avoid the ignition component 4 and / or the flameout protection component 5. Through the above technical solution, the burning area of the infrared combustion structure is increased to a certain extent, the overall burning area of the burner head is further increased, and the heating efficiency of the burner head is improved. Those skilled in the art can understand.

[0041] Alternatively, when the gap between the infrared combustion structure and the open flame combustion structure is greater than the diameter of the ignition component 4, the infrared combustion structure and the open flame combustion structure have enough space to accommodate the ignition component 4 and / or the flameout protection component 5. The side wall of the first mixing cavity 11 does not need to be provided with an avoiding portion 110 to avoid the ignition component 4 and / or the flameout protection component 5, so that the vertical projection shape of the side wall of the first mixing cavity 11 is a standard shape.

When the infrared radiation type ceramic plate 2 is embedded in the first mixing cavity 11, the bottom surface of the infrared radiation type ceramic plate 2 abuts against the top surface of the supporting step 14. Through the above technical solution, the top surface of the infrared radiation type ceramic plate 2 is horizontally aligned with the top opening of the first mixing cavity 11. Those skilled in the art can understand.

[0044] Further, the furnace base 1 is further provided with an ignition hole 13, specifically, in the embodiment, the ignition hole 13 is arranged through the inner side wall of the second mixing cavity 12 and communicates with the second mixing cavity 12, so that the ignition hole 13 faces the infrared combustion structure, so as to make the gas in the open fire combustion structure flow to the infrared combustion structure, the number of the ignition hole 13 is preferably two and is arranged in a horizontal direction, when the flame generated by the open fire combustion structure is accidentally blown out, the gas can be released from the ignition hole 13 and is re-ignited by the flame generated by the infrared combustion structure, so that the open fire combustion structure recovers burning in time, through the above technical scheme, the infrared combustion structure re-ignites the open fire combustion structure, and those skilled in the art can understand it.
