Self-generating wrist ball

Details

Attorney, Agent or Firm: Rosenberg, Klein & Lee

The present invention relates to a self-generating wrist ball which includes a ball-shaped housing, a revolution ring, a flywheel and a generating and lighting mini-module. The ball-shaped housing has a plurality of protruding arched pieces to enhance the light-concentrating effect and to increase the stability when the fingers hold the wrist ball. The generating and lighting mini-module includes at least two rotor aggregates within flywheel and at least two stator aggregates corresponding to said rotor aggregates being fixed on the revolution ring. The wrist ball is self-generating in operational state by means of the impulse excitation created at the rotational moment of the wrist ball. In addition, the effect of magnetic field line can be enhanced by means of magnets and magnetic metal plates of the rotor aggregates and the stator aggregates. Furthermore, the same magnetic poles of both magnets are arranged in opposite way to prevent the flywheel from interference in rotation.

DETAILED DESCRIPTION It is a primary object of the present invention to provide a self-generating wrist ball which is so designed as if a mini-generator is provided inside by means of impulse excitation created during the moment of the rotation of the wrist ball.
Therefore, a self-generating effect during operation is created.
It is another object of the present invention to provide a self-generating wrist ball through which the problems with environmental protection caused by discarded batteries can be avoided.
It is a further object of the present invention to provide a self-generating wrist ball which continues to effectively produce electricity.
Moreover, the light can be effectively concentrated to emit blazing beams.
Besides, the generating mini-module won't affect the operation of the wrist ball inside.
