ABSTRACT:
A fan guide hood structure includes a fixing seat and a hood. The fixing seat has a hollow cylinder, which has clamping parts and guide rails arranged in symmetry at its edge and a fixing part on its top. The fixing part is designed to couple with the fan unit and the hood has a sleeve at one end. The sleeve has clamping grooves and slide grooves corresponding to said clamping parts and said guide rails and extends downwards to form a trumpet hood part. An elastic member lies between said hood part and said fixing seat and the whole structure forms a seamlessly adjustable guide hood structure.
