Abstract: A centrifugal fan impeller structure includes a hub and multiple blades extending from an outer circumference of the hub. Each blade has a fixed end, a free end, an upper end face, a lower end face, a front end face and a rear end face. The front and rear end faces define therebetween a thickness. The thickness ranges from 0.05 mm to 0.15 mm. The are two inclinations between the upper and lower end faces of the blade, whereby the thickness of the blade is minified to increase the number of the blades. By means of the inclinations, the blades are not subject to breakage in the demolding process.

Abstract: 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.

Abstract: 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.

Abstract: A fan rotor mechanism includes a fan impeller, a case and an adhesive body. The fan impeller has a hub and multiple fan blades. The hub has a first top section and a first peripheral section together defining a receiving space for receiving the case. The case has a receptacle for receiving therein at least one magnetic component. The case and the magnetic component define therebetween a filling gap. The case is formed with at least one perforation in communication with the filling gap. The adhesive body is filled up in the filling gap. By means of the structural design of the fan rotor mechanism, the fan rotor mechanism is applicable to various magnetic components with different sizes. Therefore, is unnecessary to manufacture different sizes of molds for different sizes of cases so that the fan rotor mechanism has high universality and is manufactured at lower cost.

Abstract: An anti-press fan structure includes a fan frame and a fan impeller. The fan impeller has a support shaft supporting the fan impeller disposed in the fan frame. The support shaft has a protrusion section protruding from the fan frame to bear and connect with an external unit positioned above the fan impeller so as to keep an axial space between the fan impeller and the external unit. Accordingly, the fan impeller is prevented from being compressed by the external unit and the pressure applied to the fan frame is dispersed.
