Abstract:
1. An illuminating wrist exerciser, comprising: an upper casing member and a lower casing member, which are hollow and mate each other to define an interior space therebetween, the upper casing member forming an opening in a top portion thereof; a ring, which is set on an upper circumferential edge of the lower casing member, the ring forming a joint seat and a hole opposite to each other, the joint seat forming therein a bore; a magnetic ring, which is coupled to the joint seat of the ring; a rotor, which is rotatably received in the interior space between the upper and lower casing members and has axles extending in opposite direction from opposite ends of the rotor, the rotor partially projecting beyond the opening defined in the upper casing member for receiving an external force for initiation of rotation thereof, the axles being respectively fit into the bore of the joint seat and the hole of the ring; an illumination control circuit board, which functions to realize power conversion and control of illumination, the illumination control circuit board being fit over one of the axles of the rotor and fixed to a recess defined in the corresponding end of the rotor to be rotatable in unison with the rotor; a plurality of illuminators, which are arranged on a circumferential surface of the rotor and are electrically connected to the illumination control circuit board to be driven by the illumination control circuit board for lighting; and a coil holder, which is fixed to the recess on the end of the rotor, the coil holder having an inner circumference to which at least one pair of coils is mounted, each coil being electrically connected to the illumination control circuit board, the coil holder forming a bore in which the magnetic element is received in such a way that the magnetic element and the coils are set in a co-planar arrangement, whereby when the coils are rotated with the rotor and orbiting around the magnetic element, electrical power is induced therein for supplying to the illumination control circuit board.
