Abstract: A centrifugal fan includes a housing, a driving device, and a fan impeller. The housing has a hollow chamber which has a central axis. The driving device is located at the central axis of the hollow chamber. The fan impeller is disposed in the hollow chamber and includes a hub, several blades, and several fins. The hub is connected with the driving device. The blades are disposed around the hub. Each blade has a windward surface and a leeward surface. Each fin extends from the windward surface of one of the blades, outward by an arc surface from the windward surface starting from a location near the central axis, and further extends to the leeward surface of an adjacent blade.

Abstract: A multipurpose float is provided which employs a rotatable bar attached to a main body of the float. Four bolts, each having a snap ring disposed at the bolt head, are located in four deep holes respectively formed in four sides of the main body. The rotatable bar can be set perpendicular to the main body to prevent the float from jumping out from between the thighs of a user. Further, a plurality of the floats can be combined to form a large sized floating bed.
