This utility model discloses an oxygen-enriched combustion air supply device for a cremator, comprising a housing, a circulation pipe, and a cylindrical shell. An oxygen-enriched membrane oxygen generator and a fan are installed inside the housing. A discharge pipe is installed on the right side of the housing, connecting to the oxygen-enriched membrane oxygen generator and the fan. The circulation pipe is connected to the discharge pipe, and its other end connects to the air inlet of the fan. The cylindrical shell is installed on the inner wall of the housing, and a corrugated airbag is connected inside the cylindrical shell. An electric cylinder is installed on the cylindrical shell, connected to the left end of the corrugated airbag. A portion of the oxygen produced by the oxygen-enriched membrane oxygen generator is stored in the corrugated airbag. When the demand for oxygen-enriched air decreases, the corrugated airbag can be stretched to collect oxygen, reducing waste. When the demand for oxygen-enriched air increases, the electric cylinder compresses the corrugated airbag, delivering oxygen into the air and increasing the oxygen concentration, thus achieving flexible supply of oxygen-enriched air.
