Description
Technical field
The utility model relates to the power-saving technology of electric equipment products.
Background technology
In the actual life, the phenomenon of energy waste is seen everywhere.
For example, such as TV,, then still can absorb electric energy if does not pull up from supply socket household electrical appliance such as computer shutdown back.According to USDOE's statistics, the power consumption under this off-mode has accounted for about 20% of the whole America total electricity consumption unexpectedly.
Rechargeable battery (or claiming secondary cell) is the electric product that modern society very generally uses.Rechargeable battery is carried out the charger ubiquity and waste phenomenon, thereby cause huge energy waste.
With present widely used charger for mobile phone.According to the investigation of Nokia, in the whole life of mobile phone products, power consumption has 2/3rds from the wasting of charger, and promptly mobile phone still is inserted in and produces power consumption on the socket being full of electricity back charger.
For general charger, people are also usually untimely to pull up charger from supply socket.And these chargers are owing to be connected with external power source for a long time, and still there is a spot of energy consumption in its inner transformer.If consider the huge of its usage quantity and with the length of external power source connect hours, the energy loss that is brought also is very huge.
Various energy-conservation chargers have appearred in the market.For example, the charger for mobile phone of a kind of environmental protection power saving design is on being inserted in supply socket the time, if do not connect mobile phone, charger will be in complete closing state so, have no power consumption.But this charger can not be in complete closing state after mobile phone is full of electricity.Therefore, its energy-saving effect still awaits improving.
And for example, a kind of energy-saving charging device is arranged, adopt new single-chip microcomputer V2.0 platemaking technology, combined new-dV to be full of judgment technology, make that to be full of judgement more accurate.It has and is full of electricity and keeps function, makes battery remain fully charged state and trickle charge.But this charger is not still accomplished good energy-conserving action.Because after battery is full of, the trickle of the charger consumed power that still can work on.This a part of natural wastage compare battery electric quantity we can say very little, but the power supply that will use 220V directly supply satisfy trickle, efficient is very low.
Summary of the invention

Embodiment
Some embodiments below in conjunction with description of drawings the utility model.
The schematic block diagram of the electric supply installation that Fig. 1 the utility model is related.As shown in Figure 1, this electric supply installation 1 comprises: power input unit 10 is connected to receive the power supply of external power source with external power source.This power input unit 10 can comprise a transformer, and two inputs on its former limit are connected with the power supply terminal of external power source, and the secondary of transformer connects power conversion unit 20.
External power source is delivered to power conversion unit 20 after the transformation of transformer, handled by power conversion unit 20.For example power conversion unit 20 can comprise conventional rectification circuit, and the alternating current of importing is carried out rectification, output DC.In addition; Power conversion unit 20 can also comprise the circuit that the direct current after the rectification is further handled, for example voltage stabilizing circuit, voltage conversion circuit (boost decompression transformation, positive-negative polarity conversion, single supply and positive-negative power conversion, single supply and many power source conversion etc.), protective circuit (short-circuit protection, overvoltage protection, under-voltage protection, overcurrent protection and other protection etc.).These circuit modules can utilize existing circuit to realize according to the function needs of electric supply installation.Repeat no more in this specification.
Electric energy after power conversion unit 20 is handled offers the power unit that needs power supply via output port 30 outputs.Control unit 40 is connected between output port 30 and the input unit 10, can be according to the electrical energy parameter (for example size of current, voltage height etc.) by output port 30 outputs, the input on the former limit of transformer and the on/off of external power source in the control input unit 10.For example, when the electric current of output port 30 output during, the input on the former limit of transformer is connected with the external power source disconnection less than predetermined value.Control unit 40 can adopt miniaturized electronic devices such as relay to realize.
The electric supply installation 1 of the utility model can be installed in the various electric equipments; Particularly be adapted to be mounted within for example TV of those electric equipments that possibly be in holding state for a long time; In computer, the charger etc., can be under standby or the idle situation at these electric equipments through judgement like this electric supply installation 1 output electric energy situation; The cut-out electric supply installation is connected with external power source, thereby thoroughly stops the useless consumption of electric energy in this case.
Fig. 2 is the circuit theory diagrams of the charging device of an embodiment of the utility model.
As shown in the figure, fine line part illustration goes out the charging circuit of a routine among the figure.The scheme that connects a relay 400 in the transformer T secondary circuit that heavy line partly shows at above-mentioned charging circuit between charging voltage output and the external power source input.The loop A of relay 400 is connected in the charging voltage outlet line, and relay trigger switch B then is connected in the former limit of the transformer T circuit of charging circuit.
In this example, select moving fault (D type) relay of 200mA outage for use at the relay 400 that secondary circuit adds.When electric current in the output circuit was the operate as normal size, because electromagnetic action, contact switch B was closed, switches in the circuit of former limit.When the electric current of output less (because now mobile phone is to the protective effect of battery, charging is accomplished when the back output current is compared charging and can be reduced a lot), contact switch B is owing to electromagnet magnetic force reduces to separate, thereby breaks off being connected of former limit circuit and external power source.
In addition, a reset switch can also be set on relay 400.Make relay after the contact is broken off, can charging device can be restarted through the hand-reset closure.
In another example, also can use transistor as control element.For example, in the base stage access secondary output port circuit with NPN formula triode, collector and emitter is inserted between transformer former limit input and the external power source.So just can be through the base stage of the Current Control triode in the secondary output port circuit, conducting and disconnection between controlling between the collector and emitter of triode thus, and then control being connected of former limit circuit and external power source.
The above is merely some embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
