Summary:The utility model discloses an axial flow air exhaust fan structure which comprises a fan assembly and a driving motor. One end of each blade is fixedly connected with the inner wall of the annular base, the blades are evenly distributed in the circumferential direction of the inner wall of the annular base, and a channel used for airflow circulation is formed between the center shaft part of the annular base and the adjacent blades; the annular base is mounted in the rotating bearing; the annular base is driven by the driving motor to rotate in the rotating bearing, and then the blades are driven to rotate to generate thrust on gas. The central shaft driving mode of a traditional fan blade is changed, the multiple blades are evenly arranged on the inner wall of the annular base in the circumferential direction, a channel used for airflow circulation is formed between the central shaft part of the annular base and the adjacent blades, the airflow passing amount is increased, and the air exhaust strength is en
