Abstract
The utility model provides an energy-saving charging device, which comprises an alternating current input terminal. The alternating current input terminal is connected with a switch power supply unit connected with a charging output terminal, a circuit break controller is arranged between the alternating current input end and the switch power supply unit, a control end of the circuit break controller is connected with one end of a work state detection unit, and the other end of the work state detection unit is connected with the charging output terminal. In the energy-saving charging device, the work state detection unit is used for judging whether the charging device is connected with an electric appliance or not, if not, the circuit break controller is controlled to be disconnected to lead the switch power supply unit to be in non-working state, thereby even people do not pull an alternating current from the charging device after charging, large power consumption can be avoided, and the charging device saves electricity.
Description
Technical field
The utility model relates to a kind of charging device, particularly a kind of energy-saving charging device.
Background technology
Charging device is mainly used in small electric apparatus is charged, generally comprise alternating current input terminal, switching power supply and charging lead-out terminal, by switching power supply alternating current is carried out transformation and rectification, thereby the direct current of output certain voltage on the charging lead-out terminal, the direct current by this certain voltage charges to electrical equipment.Because switching power supply comprises a lot of transformations and rectifying device, and these often have bigger power loss.
A lot of people's electrical equipment are directly pulled up electrical equipment, and charging device are not unpluged from alternating current after charging is finished from charging device.Charging device is under the state that does not charge, and switching power supply still is in running order, consumes a large amount of electric energy.Country advocates energy-conserving and environment-protective and energy savings now, wish that people change these bad habits and customs, but under the situation that much people's habits and customs also do not change fully at present, how to realize that in technology the energy-conservation of charging device is the important topic of pendulum in face of us.
Summary of the invention
At above defective, the energy-saving charging device that the utility model provides, judge whether be connected with electrical equipment on the charging device by the operating state detecting unit, if just not controlling broken-circuit controller disconnects, thereby make switching power supply be in off position, even people did not unplug charging device after therefore charging was finished from AC power, can not produce very big power consumption, saves energy yet.
The technical scheme in the invention for solving the technical problem is:
A kind of energy-saving charging device, comprise the alternating current input terminal, this alternating current input terminal connects switching power supply, this switching power supply connects the charging lead-out terminal, between above-mentioned alternating current input terminal and switching power supply, also be provided with broken-circuit controller, the control end of this broken-circuit controller connects an end of operating state detecting unit, and the other end of this operating state detecting unit connects above-mentioned charging lead-out terminal.
Preferably, above-mentioned operating state detecting unit further comprises current detection module, electric current judge module and signal output module, and this current detection module connects above-mentioned charging lead-out terminal, and above-mentioned signal output module connects the control end of above-mentioned broken-circuit controller.
Preferably, this device also comprises exchanges data unit and data terminal, and above-mentioned charging lead-out terminal is the USB interface terminal, and above-mentioned exchanges data unit is connected with above-mentioned charging lead-out terminal.
Operation principle: the energy-saving charging device that the utility model provides is provided with broken-circuit controller between alternating current input terminal and switching power supply, the control end of this broken-circuit controller connects the operating state detecting unit, the other end of this operating state detecting unit connects the charging lead-out terminal, the operating state detecting unit detects the charging lead-out terminal during work, if charging device unplugs the variation that the operating state detecting unit can detect signal, and the control broken-circuit controller disconnects the connection between alternating current input terminal and the switching power supply, switching power supply is in power save mode, thereby realizes the purpose of automatic energy saving.The operating state detecting unit further comprises current detection module, electric current judge module and signal output module, current detection module connection charging lead-out terminal is used to monitor the electric current situation of change on the charging lead-out terminal, electric current on the charging lead-out terminal diminishes suddenly, the electric current judge module is judged charging device according to the electric current situation of change and is unpluged, thereby the control signal output module sends break signal, and broken-circuit controller begins to open circuit after receiving this break signal.
In preferred version of the present utility model, the charging lead-out terminal is the USB interface terminal, also comprise exchanges data unit and data terminal, the charging lead-out terminal can connect the digital product of similar digital camera or USB flash disk, data terminal can connect computer, realize exchanges data by the exchanges data unit, thus the purpose that realization manages by computer logarithmic code product.
Beneficial effect: the energy-saving charging device that the utility model provides, judge whether be connected with electrical equipment on the charging device by the operating state detecting unit, if just not controlling broken-circuit controller disconnects, thereby make switching power supply be in off position, even people did not unplug charging device after therefore charging was finished from AC power, can not produce very big power consumption, saves energy yet.
