Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 , Figure 2 As shown, a dual-ejector three-ring burner for a stove includes a burner head 1, a flame distributor seat 2, a central annular flame cap 3, an inner ring flame cap 4, and an outer ring flame cap 5.

[0025] The burner head 1 includes a base plate 11, a central air inlet pipe 12, a central ejector pipe 13, an outer ring air inlet pipe 14, and an outer ring ejector pipe 15. The central vertical pipe 121 of the central air inlet pipe 12 intersects with the base plate 11, and the central horizontal pipe 122 is connected to the central ejector pipe 13. The outer ring vertical pipe 141 of the outer ring air inlet pipe 14 intersects with the base plate 11, and the outer ring horizontal pipe 142 is connected to the outer ring ejector pipe 15.
