Wireless Powered Dual Fans

Abstract

A wirelessly powered dual-fan assembly includes a power supply fan, a power supply coil, a receiving fan, and a receiving coil. The power supply fan incorporates a first control unit, which is electrically connected to an external power source. The power supply coil includes a first coil, which is sleeved on the outer wall of the power supply fan and electrically connected to the first control unit. The receiving fan is located on one side of the power supply fan and incorporates a second control unit. The receiving coil includes a second coil disposed opposite to the first coil, which is sleeved on the outer wall of the receiving fan and electrically connected to the second control unit. The first coil receives alternating current and generates an alternating magnetic field, inducing a current in the second coil, which is then supplied to the receiving fan. This allows the dual fans to be powered by a single power supply wire, reducing the number of wires and preventing tangling or knotting.
