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

Digital camera USB charger with wireless charging function
Technical field
The utility model belongs to the digital camera auxiliary device, relates in particular to a kind of digital camera USB charger with wireless charging function.
Background technology
Present digital camera functionality is more and more abundanter, and it is smaller and more exquisite that size becomes, and makes the size decreases of battery, and capacity diminishes, and shorten the service time of battery, and the user misses splendid moment because of dead battery through regular meeting.Present camera charging method mainly contains the USB charging, battery tray formula charger charging etc., and these charging modes all will be subjected to the restriction of voltage source, do not possess the function of charging for camera whenever and wherever possible.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of digital camera USB charger with wireless charging function is provided, reequip at existing USB charger, make it when possessing the generic USB charge function, also possess and receive the external electromagnetic ripple and convert thereof into the wireless charging function that electric current is the camera charging, realize charging whenever and wherever possible, both power savings, convenient again.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of digital camera USB charger with wireless charging function, be built-in with the generic USB charging circuit and be connected at the charger housing with USB interface on placing housing, it is characterized in that: described generic USB charging circuit is connected with the wireless charging circuit by switching circuit, described wireless charging circuit is made of the antenna, receiver, electromagnetic inductor, the filter circuit that connect successively, and described filter circuit is connected with switching circuit.
Described switching circuit is connected successively with charge protector, Mini USB interface.
Beneficial effect: utilize the electromagentic resonance principle that the electromagnetic wave in the environment is incorporated in the charger by reception antenna,, make it produce electric current and be used for battery charge through the processing of electromagnetic inductor and filter.Wireless charging and the coexistence of generic USB charge function, the work by two kinds of patterns of switching circuit control when inserting extraneous power supply, will stop the wireless charging pattern when switching circuit detects the generic USB charging signals, carry out the generic USB charging; When pulling up extraneous power supply, the USB charging signals disappears will stop the generic USB charge mode, carry out wireless charging.The wireless charging function is fused in the common USB charger, makes it can carry out wireless charging and also can use as the common USB charger.
