Abstract: A fan assembly includes a mounting bracket, a fan, and a baffle. The mounting bracket includes two side plates bounding an outlet, and each side plate defines a through hole. An inner side bounding the through hole defines an arc-shaped cutout, communicating with the through hole. The baffle includes two pins rotatably received in the through holes of the side plates. A protrusion protrudes out from each pin, and is engaged in the corresponding cutout. When the fan operates, the baffle is pushed to rotate to open the outlet, to allow air from the fan to flow out through the outlet. When the fan ceases operation, the baffle rotates back under force of gravity to a position to cover the outlet, where the protrusion resists against one end of the cutout such that further rotation is prevented, to prevent air intake into the mounting bracket through the outlet.
