1. A fan module, comprising:
a blade assembly, having a plurality of fan blades and a bottom plate, wherein the bottom plate is connected to the fan blades, and at least one first opening and at least one protrusion are formed on the bottom plate;
a rotating shaft assembly, affixed to the bottom plate, wherein the rotating shaft assembly has at least one first slot and at least one second opening, the first slot corresponds to the at least one protrusion, and the at least one second opening corresponds to the at least one first opening; and
a plate member, movably disposed between the bottom plate and the rotating shaft assembly, and the plate member having at least one second slot,
wherein the at least one second slot is sleeved on the at least one protrusion, and a size of the at least one second slot is greater than a size of the at least one protrusion;
wherein when the rotating shaft assembly drives the blade assembly to rotate, the plate member rotates relative to the bottom plate, thereby selectively shielding the first opening or exposing the first opening.
