The invention relates to the technical field of jet propulsion, and provides a speed-staggered micro-mixing nozzle structure and a combustion chamber. The micro-mixing nozzle structure comprises a mounting seat and a first nozzle unit, the first nozzle unit is arranged on the mounting seat; the first nozzle unit comprises a plurality of reference position pre-mixing micropipes and a plurality of staggered position pre-mixing micropipes; the plurality of reference bit pre-mixing micropipes and the plurality of staggered bit pre-mixing micropipes are arranged side by side, and the plurality of staggered bit pre-mixing micropipes are arranged among the plurality of reference bit pre-mixing micropipes; the outlet end of the staggered position premixing micropipe is flush with the outlet end of the reference position premixing micropipe; the outlet end of the staggered position premixing micropipe and the outlet end of the reference position premixing micropipe have different jet flow speeds on mixed gas, so that
