Backfire oxygen-enriched energy-collecting gas stove

The utility model relates to a gas stove and in particular relates to a backfire oxygen-enriched energy-collecting gas stove and belongs to the technical field of gas stoves. The backfire oxygen-enriched energy-collecting gas stove comprises two two-gear four-ring backfire combustion assemblies, wherein a gas inlet bracket is arranged at the middle part of a panel and is respectively connected with a left two-gear four-ring backfire combustion assembly and a right two-gear four-ring backfire combustion assembly by virtue of two air pipes; the upper surface of each two-gear four-ring backfire combustion assembly is connected with a plurality of movable cookware support racks by virtue of a hinged pillar; a plurality of movable cookware support racks are uniformly distributed in the peripheral direction of each two-gear four-ring backfire combustion assembly; each two-gear four-ring backfire combustion assembly comprises a two-gear four-pipe mixer; the upper end of the two-gear four-pipe mixer is connected with a pivot plate; a central fire cover is arranged at the center of the upper end of the pivot plate; a soft fire channel cover is arranged on an outer ring of the central fire cover; a high fire channel cover is arranged on an outer ring of the soft fire channel cover; a lifting hearth is arranged on an outer ring of the high fire channel cover. According to the gas stove, the gas is introduced by a main combustion mixture gas channel and a secondary combustion mixture gas channel; main combustion mixture gas and secondary combustion mixture gas are supplemented with each other during combustion; the main combustion flame rolls, rotates and combusts, so that the combustion time is prolonged; the utilization rate of the heat energy is improved.
