Background technology
Modern society is a society with fast rhythm, is a headachy thing such as the battery charge of various portable electric appts such as mobile phone, personal electric assistant (PAD), MP3.Except using the different chargers because of different electronic products, also need seek suitable socket during charging, use very inconvenient, though occur the charge power supplies of using on the market more, but can not be reasonably charge according to the electric weight of equipment needs, at present, most people is when using electronic product, all be to be inserted in charge power supply above the supply socket for a long time for avoiding trouble, need to use and just directly be inserted on the electronic product that needs charging, certainly will cause charger when not using, to use electrical loss like that, and analyze according to the normal life custom, be no more than 8 hours the service time of charge power supply actual every day, and other l6 hour be to be in fully not have waste of energy period of using, according to the charge power supply quiescent dissipation of the energy-conservation requirement in the present world per hour 0.3W calculate, 2,000,000,000 mobile phones or the electric energy loss of electronic product charge power supply static state hourly are 600,000 kilowatts, l6 hour waste electric energy is: 9,600,000 kilowatts, the charge power supply waste of electric energy is huge unusually; And there is very high security risk in product, if the product quality of charger existing problems, long-term plug-in work temperature will occur and raise, potential safety hazard such as on fire, and be inserted in for a long time on the power supply, the inner body of charger power supply works long hours, part life can gradually reduce, the charger life-span is lowered greatly, cause the wasting of resources, damage to the environment.
The utility model content
The technical problems to be solved in the utility model is for overcoming weak point of the prior art, provide a kind of simple structure, volume small and exquisite, be convenient to deposit, carry, novel energy-conserving charger easy to use.
For solving technical problem of the present utility model, the technical scheme that adopts is: a kind of novel energy-conserving charger, comprise the power connector end mouth, input part, efferent, described input part is connected with described power connector end mouth, described power connector end mouth connects external power supply, be used to described input part that input voltage is provided, described input part comprises change-over circuit, the high frequency conversion circuit, described change-over circuit is connected with described high frequency conversion circuit, described high frequency conversion circuit is connected with efferent, described efferent comprises the power rectifier module, output port, described power rectifier module is connected with output port, also be provided with the power down switch module between described power connector end mouth and the output port, the Energy Saving Control module, described power down switch module is arranged between power connector end mouth and the output port, and described Energy Saving Control module is connected between described power down switch module and the output port;
Described input part and efferent are provided with heat sink.
Beneficial effect with respect to prior art is, the Energy Saving Control module can be identified the load of powering, as long as connect load, the Energy Saving Control module sends control signal to the power down switch module, control power down switch module is connected power interface according to the control signal of receiving, and power supply can quit work automatically after removing load, can save considerable electric energy, and by this switching circuit conducting or disconnect to realize the idle function of charger, satisfy environment protection requirement better.
Description of drawings
Fig. 1 is framework map of the present utility model.
Embodiment
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
As shown in Figure 1, this novel energy-conserving charger simple structure, volume small and exquisite, be convenient to deposit, carry, easy to use.This novel energy-conserving charger, comprise power connector end mouth 5, input part 7, efferent 8, described input part 7 is connected with described power connector end mouth 5, described power connector end mouth 5 connects external power supply, be used to described input part that input voltage is provided, described input part comprises change-over circuit 2, high frequency conversion circuit 3, described change-over circuit 2 is connected with described high frequency conversion circuit 3, described high frequency conversion circuit 3 is connected with efferent 8, described efferent 8 comprises power rectifier module 4, output port 9, described power rectifier module 4 is connected with output port 9, also be provided with power down switch module 1 between described power connector end mouth 4 and the output port 9, Energy Saving Control module 6, described power down switch module 1 is arranged between power connector end mouth and the output port, and described Energy Saving Control module 6 is connected between described power down switch module and the output port;
Described input part and efferent are provided with heat sink.
During use, output port is inserted into corresponding electronic products, output port adopts general USB port, and the various electronic products of convenient connection are because these electronic products generally have a constant impedance, the Energy Saving Control module detects the impedance signal of electronic product, through the analysis identification of Energy Saving Control module, send control signal to the power down switch module, the power down switch module is connected output port according to the control signal that receives, charger is started working, the output electric weight; After pulling out the load electronic product, the impedance of load disappears, and this moment, the Energy Saving Control module sent cut-off signal to the power down switch module, and the input power supply is disconnected and quits work, and charger is in out-of-work state; When circuit was connected, the input voltage that change-over circuit is used for the power connector end mouth was converted to the voltage that is fit to the high frequency conversion circuit, and change-over circuit is connected with the high frequency conversion circuit; This high frequency conversion circuit is converted to the direct voltage of change-over circuit output the alternating voltage of high frequency, this high frequency conversion circuit adopts full-bridge or half-bridge topology circuit, this high frequency conversion circuit is connected with the power rectifier module, behind the alternate voltage rectification of power rectifier module to the high frequency of high frequency conversion circuit output, the electronic product of input connection is easy to use again.
Because energy delivered is big between input part and the efferent, make each device on input part and the efferent generate heat easily, for this reason, also on input part and efferent, respectively put the heat energy that heat sink disperses each device, guarantee stable, useful life of prolonging product of each device with this.
The above execution mode only is used for illustrating the utility model, but is not limited thereto.Under the condition that does not depart from the utility model design, affiliated technical field personnel can make suitable change adjustment, and these change adjustment also should be included within the claim protection range of the present utility model.
