MAGNETIC SHAFT OF A COOLING FAN

摘要

The present invention provides an improved structure of the magnetic shaft of a cooling fan. A magnetic attraction component is comprised of a magnetic ring, a magnetic inductive bottom board, and a magnetic inductive ring. The magnetic field generated by the magnetic ring is guided from the upper and lower side by the magnetic inductive ring and the magnetic inductive bottom board respectively, so that the range of magnetic field scattered by the magnetic ring is effectively and reliably guided and suppressed. The range of the magnetic field is reduced to the smallest possible, and interference with other components is minimized within the cooling fan, working stability and quality of the cooling fan being enhanced.
