摘要： A fan blade with improved structure includes a hub, a plurality of blades. The hub has a lateral side having two ends, one of which is formed a top side and the other end is extended to form an extended section, and a plurality of connecting slots located on the periphery of the extended section. Each blade has a first end correspondingly engaged in respective connecting slot and a second end. With these arrangements, the fan blade with improved structure can increase structural strength of thin fan blades and be easy to connect the hub to the blades.

摘要： A tray-type fan impeller structure includes a plate body annularly disposed around a hub. The plate body has a connection side connected with the hub and a free side extending in a direction away from the hub. Multiple boss bodies are arranged on a top face or the top face and a bottom face of the plate body at intervals. By means of the boss bodies, the periodical noise problem caused by the conventional blades is improved.

摘要： A disk-shaped fan impeller structure includes a plate body having an inner rim and an outer rim. The inner rim is connected with a hub via multiple connection members. The outer rim extends in a direction away from the hub. The connection members are annularly disposed on outer circumference of the hub at intervals to radially extend toward the inner rim of the plate body. A top face and a bottom face are defined between the inner rim and outer rim. Multiple upper boss bodies are arranged on the top face at intervals. Multiple first gaps are distributed between the upper boss bodies. By means of the boss bodies, the periodical noise problem of the conventional fan impeller can be improved.

摘要： The present invention relates to an improved structure of fan blades, which comprises a hub, a connecting part, and a plurality of fan blades. The connecting part has a coupling section and a plurality of slits. The connecting part is sleeved around the perimeter of the hub through the coupling section. The slits are circularly disposed close to the perimeter of the connecting part. The fan blades individually have a first end and a second end; the first ends are individually embedded in the slits and combined with the connecting part. Be means of the present invention, the disadvantage of the combination through a non-integrated structure of the fan blades and the hub in the prior art can be overcome.
