Abstract
The utility model relates to a digital camera USB charger with wireless charging function, wherein a common USB charging circuit is arranged in a charger casing, and is connected with a USB interface on the casing. The digital camera USB charger is characterized in that the common USB charging circuit is connected with a wireless charging circuit through a switch circuit, the wireless charging circuit is composed of an antenna, a receiver, an electromagnetic inductor and a filter circuit, which are connected in turn, and the filter circuit is connected with the switch circuit. The digital camera USB charger has the benefits that electromagnetic waves in environment are led to the charger through the receiving antenna by means of electromagnetic resonance principles, and are processed by the electromagnetic inductor and an electric filter to generate electric current for charging batteries. The wireless charging function and the common USB charging function coexist, the wireless charging function is merged into a common USB charger, thereby the USB charger can wirelessly charge, and also can be used as a common USB charger.
Description
Technical field
