[0035] In the present utility model, the outer ring mixing cavity 30 and the structure of the injection channel 31 with a single injection are formed by surrounding with the gas distribution cover plate 20 and the gas distribution housing base 10 which are spliced up and down; moreover, through the staggered arrangement structure on the upper and lower sides of the gas distribution cover plate 20, the middle mixing cavity and the central gas guiding channel 22 separated from the injection channel 31 can be effectively formed; by using the central gas guiding channel 22, part of the gas in the outer ring mixing cavity 30 can be transferred to the central mixing cavity 32, so as to form a two-ring fire burner structure with two gas distribution output channels; under the condition of maintaining the simple burner structure of the single injection channel 31, a double gas distribution output channel that can match the double-ring fire gas supply requirement is provided.
[0036] In this embodiment, in order to make the gas supply in the central mixing cavity 32 more uniform, two central gas guiding channels 22 are provided, and are symmetrically arranged on the opposite sides of the injection cover groove 21.
[0037] Furthermore, both the front and rear ends of the central gas guiding channel are connected to the outer ring mixing cavity 30; the central mixing cavity 32 is located above the middle of the central gas guiding channel. The front and rear ends of the central gas guiding channel can transfer the gas in the outer ring mixing cavity 30 to the central mixing cavity 32 above the middle, and the gas supply is more uniform.
