Electric air pump having multiple impellers and method

An electric air pump comprising:

• an outer housing having an air intake port and an air exhaust port, said out housing comprised of plastic;
• an electric motor mounted with in said outer housing, said electric motor having a rotating output shaft;
• a plurality of air impellers each having a plurality of fins and each parallel mounted on said rotating output shaft for drawing a volume of air through said air intake port and across said electric motor, said plurality of air impellers comprising a first air impeller and a second air impeller;
• and
• an air compressor chamber positioned between and in mechanical communication with said electric motor and said air impellers and being stationarily mounted to said electric motor, said air compressor chamber having a plurality of centrifugal channels for directing said air through a plurality of windows and a corresponding plurality of triangular depressions to said air impellers, said air inpellers compressing and exhausting said air trough said air exhaust port for providing a supply of pressurized air.

An electric air pump comprising:

• an outer housing having an air intake port and an air exhaust port;
• an electric motor mounted within said outer housing, said electric motor having a rotating output shaft;
• a plurality of air impellers each parallel mounted on said rotating output shaft for drawing a volume of air through said air intake port and across said electric motor, each of said air impellers including a plurality of fins;
• an air compressor chamber positioned between and in mechanical communication with said electric motor and said air impellers and being stationarily mounted to said electric motor, said air compressor chamber having a plurality of centrifugal channels for directing said air through a plurality of windows and a corresponding plurality of triangular depressions to said air impellers, said air impellers compressing and exhausting said air through said air exhaust port for providing a supply of pressurized air;
• and
• an air directional disk positioned between said air impellers and molded to an inside surface of said outer housing for directing said air to said air impellers.
