The invention relates to a
combustor for cooking utensils. The
combustor comprises a base, an outer ring fire cover, a first outer ring ejector tube and a second outer ring ejector tube, wherein the outer ring fire cover covers a top opening of an outer ring cavity body of the base and an outer ring
gas mixing chamber is formed by encircling the outer ring fire cover and the outer ring cavity body; the first outer ring ejector tube is horizontally arranged on the base and communicates with the outer ring
gas mixing chamber; and the second outer ring ejector tube is horizontally arranged on thebase, the second outer ring ejector tube and the first outer ring ejector tube are arranged at intervals, and the second outer ring ejector tube communicates with the outer ring
gas mixing chamber. The
combustor is characterized in that a first gas ventilation hole, communicated with the outer ring gas
mixing chamber, of the first outer ring ejector tube is basically in L shape, and the first gasventilation hole is adjacent to the inner ring wall of the outer ring cavity body; a second gas ventilation hole, communicated with the outer ring gas
mixing chamber, of the second outer ring ejectortube is also basically in L shape, and the second gas ventilation hole is adjacent to the outer ring wall of the outer ring cavity body; and a partitioning plate is arranged between the second gas ventilation hole and the first gas ventilation hole. By adopting the combustor disclosed by the invention, the two-sided gas can smoothly and quickly flow to respective directions and opposed-impingement phenomenon is avoided, a
flame state of the whole combustor is better, and the gas can come out more evenly.
