Abstract:
A wireless mouse induction power supply comprising a wireless mouse and a mouse pad, characterized in that:the wireless mouse is installed with a first induction coil which is connected to a first capacitor of a power supply circuit in parallel so as to form a parallel connected oscillating circuit; the oscillating circuit is connected to a charging capacitor through a diode so as to form an induction power supply circuit; a second coil is embedded in the mouse pad; the second coil is connected to a power wire for supplying power; when power is inputted into the second coil in the mouse pad and then electromagnetic wave is generated, the electromagnetic wave is received by the first induction coil in the wireless mouse; the first induction coil will generate an electromotive potential so as to oscillate with the first capacitor of the power supply circuit; then the potential will charge the charging capacitor through the diode; then, power is outputted to a transmitter in an interior of the wireless mouse; thereby, the wireless mouse remotely controls a computer; and the power of the wireless mouse will not be interrupted in use; wherein the second coil is installed on a printed circuit board; wherein a battery is connected with the charging capacitor in parallel, the battery provides power to the mouse when no mouse pad is supplied; wherein a charging seat having a printed circuit board is provided; the wireless mouse is placed on the charging seat; thereby, the charging battery being charged.
