Abstract
A fan anti-foreign matter structure includes a fan frame, and a fan wheel mounted in the fan frame to leave only the gap between the fan hub and a fan frame axle seat disk or a circuit board on a fan hub and the axle seat disk (i.e. fan hub interior space air outlet). The fan wheel is equipped with an air diversion radiator plate surrounding a rotating shaft, so that air ducts are defined between airflow guide ribs and airflow guide ring of the air diversion radiator plate. Each air duct has an air inlet slot one side, and an airflow turning curved surface on the other side for squeezing airflow entering the air duct outward to discharge hot air downward so that a positive pressure is formed at an air outlet to prevent dirty air containing dust, salt, etc. from the external space from entering a fan hub.
