The central ejector tube, the outer ring fire mixing chamber, and the outer ring fire gas outlet groove are respectively disposed on the base. The central ejector tube is located in the middle of the base. The two sides of the outer ring fire mixing chamber are inclined outward and upward to form a first gas guide channel and a second gas guide channel. The gas outlet of the central ejector tube is connected to the outer ring fire mixing chamber. The outer ring fire mixing chamber is connected to the outer ring fire gas outlet groove through the first gas guide channel and the second gas guide channel.

[0005] This technical solution also includes an outer ejector tube, a central flame mixing chamber, and a central flame outlet. The outer ejector tube, the central flame mixing chamber, and the central flame outlet are respectively disposed on the base. The outer ejector tube is located outside the central ejector tube, and the outlet of the outer ejector tube is connected to the central flame mixing chamber. The central flame mixing chamber is inclined inward and upward, and the central flame mixing chamber is connected to the central flame outlet.

[0006] In this technical solution, the bottom of the outer ring gas outlet groove slopes outward and upward from the connection between the first gas guide channel and the second gas guide channel.

[0007] This technical solution also includes a gas equalization plate, which is disposed on the outer ring fire outlet groove and located above the outlet of the first and second air guide channels.

[0008] The advantages of this invention compared to the prior art are: the gas in the outer ring fire mixing chamber flows better into the end of the outer ring fire outlet groove, the gas distribution in the outer ring fire outlet groove is uniform, the combustion is more uniform, and the combustion efficiency is high.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] In the description of this utility model, the terms "outer" and "upper" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not require that this utility model must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "set up," "connect," and "install," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a detachable set, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figures 1 to 5As shown, it is a type of burner head, including a base 5 and an outer ring fire gas outlet groove 7; characterized in that it also includes a central ejector tube 1 and a central fire mixing chamber 3; the central ejector tube 1, the outer ring fire mixing chamber 3 and the outer ring fire gas outlet groove 7 are respectively disposed on the base 5, the central ejector tube 1 is located in the middle of the base, the two sides of the outer ring fire mixing chamber 3 are inclined outward and upward to form a first gas guide channel 31 and a second gas guide channel 32, the gas outlet of the central ejector tube 1 is connected to the outer ring fire mixing chamber 3, and the outer ring fire mixing chamber 3 is connected to the outer ring fire gas outlet groove 7 through the first gas guide channel 31 and the second gas guide channel 32.
