Energy-saving high-pressure axial flow fan

The utility model belongs to the technical field of ventilation, and particularly relates to an energy-saving high-pressure axial flow fan which comprises a fan shell, a motor base is arranged on the inner wall of the bottom of the fan shell, an axial flow motor is arranged on the motor base, a plurality of axial flow blades are arranged at the output end of the axial flow motor in an annular matrix array mode, and the axial flow blades are arranged on the motor base. The fan comprises a fan shell, axial flow blades are arranged in the fan shell, the axial flow blades are arranged in the fan shell, air guide grooves used for enhancing air flow passing pressure are formed in the axial flow blades, a circle of sawtooth-shaped outer edge is formed in the air inlet side of each axial flow blade, and a power line box is arranged on the side face of the fan shell. And the sawtooth-shaped outer edges are arranged on the air inlet sides of the blades, so that the blades can bear more pressure given by airflow in the
