Abstract

A wireless power supply device adapted to wireless supply power to an electricity receiving object is provided. The wireless power supply device includes a transformer, a wireless power supply module, and an indicator. The wireless power supply module is coupled to the transformer to wirelessly supply electricity of the transformer to the electricity receiving object. The indicator is coupled to the wireless power supply module to display an operation state of the wireless power supply module.

Claims

1. A wireless power supply device adapted to wirelessly supply electricity to an electricity receiving object, the wireless power supply device comprising:

a transformer;

a wireless power supply module coupled to the transformer to wirelessly supply electricity of the transformer to the electricity receiving object; and

an indicator coupled to the wireless power supply module to display an operation state of the wireless power supply module.

2. The wireless power supply device according to claim 1, further comprising:

a switch coupled to the wireless power supply module to activate or deactivate the wireless power supply module upon receiving an external instruction.

3. The wireless power supply device according to claim 1, wherein the indicator is an indicating lamp.

4. The wireless power supply device according to claim 1, wherein the indicator comprises a plurality of indicating lamps.

5. The wireless power supply device according to claim 1, wherein the indicator is a character display.

6. The wireless power supply device according to claim 1, wherein the wireless power supply module comprises:

a control circuit coupled to the indicator;
