Abstract: A fan device includes a bottom shell, a cover, and an impeller. The cover includes a main body, a support, and a spoiler. The main body has a through opening. A connection position between the support and the main body has a first folding line. The support is bended along the first folding line to form a portion of the through opening. The support is perpendicular to the main body, and is abutted against the bottom shell. A connection position between the spoiler and the main body has a second folding line. The spoiler is bended along the second folding line to locate in the through opening. An acute angle is formed between the spoiler and the surface of the main body facing away from the bottom shell. The impeller is located in an accommodating space between the cover and the bottom shell.

Abstract: An oil seal bearing of a fan includes a ring-shaped body for supporting a shaft of the fan, and a protruded portion disposed on the ring-shaped body. The protruded portion has a first slope, wherein the first slope is disposed corresponding to an inner top surface of a hub of the fan. An oil storage space is formed between the first slope, the shaft and the inner top surface for storing a lubricant. A first angle is formed by the extension of the first slope and the inner top surface, such that the lubricant is retained by the capillarity between the first slope and the inner top surface. Under this circumstance, the oil sealing is achieved without any additional oil seal, the effective bearing height is maximized, and the advantages of enhancing the supporting efficiency and lengthening the lifetime of the product are also achieved.

Abstract: A fan includes a fan frame and a rotor having a hub, a shaft connected with the hub at its rotation center, blades, and a disk structure connected with the blades and hub within the fan frame. The fan frame has a frame wall having inlet and outlet surfaces, a base carrying the rotor and frame wall, a cover on one side of the frame wall opposite to the base, and a tongue structure between the base and cover. The normal lines of the inlet and outlet surfaces are not parallel to the extension direction of the shaft. The distance between the virtual line segment of the outlet surface and shaft is the shortest distance between the shaft and outlet surface. The extended line from the center of the groove opening of the tongue structure intersects the imaginary plane where the virtual line segment and shaft are located.

Abstract: A fan frame includes a first frame and a second frame. The first frame includes at least a first sidewall and a first connecting element, wherein the first connecting element is disposed on the first sidewall. The second frame includes at least a second sidewall and a second connecting element, wherein the second connecting element is disposed on the second sidewall and at least partially overlapped with the first connecting element. The second connecting element includes a first end and a second end in a first direction, wherein the first end and the second end are bent toward the first connecting element, respectively, for grasping the first connecting element. As a result, the accuracy error and the precision error are avoided, the stresses are internally counterbalanced, and the deformation of the fan frame is avoided.
