Description
Technical field
The utility model relates to charger.
Background technology
Charger, English name Charger.The most frequently used is the equipment that a kind of alternating current by 220V is converted to low-voltage DC and directly charges the battery.Charger is used widely in all kinds of fields, as industry, communication, culture and education, publicity, health, military affairs, navigation etc., is widely used especially especially in life.Charger is to utilize electronic semiconductor components (or integrated device), and voltage and the changeless alternating current of frequency are transformed to galvanic a kind of static ac dc converter device.Take the electricity consumption occasion that storage battery is working power or stand-by power supply, charger is with a wide range of applications.
Summary of the invention
Charger in use conventionally all adopts and will after the attaching plug insertion 220V supply socket of charger, just start to charge the battery at present, and now, charger charging indicator light is bright; When battery charging reaches after certain numerical value, charger stops charging the battery, charger charging indicator light goes out, the indicator light that charged is bright, completes the charging work of this primary cell; But after completing this primary cell charging work, except the charging output circuit of battery is not in running order, other circuit still in the state of electric work.The general supply of charger (220V) is not cut off, and when holding state, charger is still consuming electric energy.The power consumption of common charger when standby, little charger is less than one watt, as charger for mobile phone; Some large-scale charger will reach nearly ten watts, or is greater than ten watts, and as accumulators group charger, general charger consumption will have several watts, as the charger of electric bicycle.Single China is minimum more than 100,000,000 at the charger of use current every day, and people start charging before conventionally adopting sleep at night, until just dial after getting up except power supply, during this, there is the dead time of several hours, if each charger is on average calculated in holding state (wasting) two hours, it is five watts that charger wastes, and a charger is exactly wasting of 0.01 degree, will consume the electric energy of 1,000,000 degree every day; As calculated less, each charger is calculated one watt, every day and is calculated one hour, also will consume the electric energy of 100,000 degree again, and how large this be waste.
The deficiency still consuming energy again after charging completes in order to overcome charger, energy savings, makes charger can initiatively cut off total power supply after charging completes, and can cut off general supply energy-saving charger and design for this deficiency.The charging control section that can cut off general supply energy-saving charger is divided and equally with existing charger by ac-dc converter circuit, charging Circuit tuning, charging, is detected control circuit, charging output circuit, charging indication etc. and form, and separately increases a mains switch.Current mains switch divides with self-locking with not with two large classes of self-locking, and the switch of self-locking generally adopts mechanical type self-locking, and after switch is pressed, the mechanical device of switch inside is fixed automatically, and normally opened contact is closed, normally-closed contact disconnects; Again press, switch unclamps just now, and normally opened contact is separated, normally-closed contact is closed.The self-locking of inductance type switch or unclamp and obtain by the coil in switch the suction producing when electric and complete, the suction that namely utilizes coil to obtain (mistakes) electricity generation (disappearance) replaces artificial Push switch to complete closing of switch.
Inductance type switch can be divided into two classes by operation principle: 1, the self-locking of inductance type switch relies on coil to obtain the suction of electric generation, its operation principle is: when switch is pressed, the normally opened contact closure of switch switches on power, coil in switch obtains electric, produces suction by holding contact closure state (switch generation self-locking); After switch coil losing electricity, suction disappears, and normally opened contact is separated, or again presses switch when switch self-locking, and switch also can unclamp, and normally opened contact is separated.2, the self-locking of inductance type switch is mechanical type, and after pressing switch, switch produces self-locking, and normally opened contact is closed, coil not electric; When coil obtains electric generation suction or manually again presses switch, switch resets, and normally opened contact is separated.
Can cut off general supply energy-saving charger is comprised of power supply control, ac-dc converter circuit, charging Circuit tuning, charging detection control circuit, charging output circuit, charging indication.Ac-dc converter circuit, the Circuit tuning that charges, charging detect control circuit, charging output circuit, charging indication formation live part, namely just the same with the composition of the charger using now; In fact power supply is controlled is exactly an inductance type mains switch, and the switch sections that power supply is controlled connects ac-dc converter circuit, controls power supply and supplies with, and coil connects charging and detects control circuit.The switch sections that power supply is controlled is controlled power supply and is supplied with ac-dc converter circuit, the circuit parallel connection of its coil and the charging indicator light in charge indicator or the indicator light circuit parallel connection of having charged, by charging detecting circuit control coil power supply, supplied with the working condition of the switch sections that coil power supply constraints power supply is controlled (closed or disconnection).According to the difference of power switch structure, the coil power supply method of mains switch is also different: 1, coil provides self-locking, during charging, in charge indicator, the coil in charging indicator light work, power control part obtains electric holding contact closed (implementation self-locking), charger keeps electricly, when charging completes, charging indicator light dead electricity, the coil in while power control part is dead electricity also, contact is disconnected, and charger cuts off general supply.2, mechanical type self-locking, self-locking by mains switch during charging keeps normally opened contact closed, after charging finishes, charging controls convert charging indicator light dead electricity, charged indicator light and switch coil obtain electric, when switch coil obtains electric generation adhesive, suction is as manually pressed switch, and switch resets, normally opened contact is separated, charger power-off.
Ac-dc converter circuit is that the alternating current of 220V is converted to the low-voltage dc power supply supply charging Circuit tuning that charger charges required; Charging Circuit tuning is that low-voltage DC is adjusted into constant voltage, constant-current supply; Charging Circuit tuning detects control circuit through charging and provides required constant voltage, constant-current supply to charging output circuit; Charging detects the continual detection charging of control circuit Circuit tuning and supplies with the numerical value such as magnitude of voltage of charging output circuit current value, rechargeable battery and provide power supply to the charging indicator light in charging indication, and charging indicator light is bright; When charging current or cell voltage reach set point, charging detects the power supply that control circuit cuts off charging indicator light in the power supply output of charging output circuit and charging indication and supplies with (charging indicator light goes out), the power supply supply (it is bright that charging completes indicator light) of indicator light of having charged in charging indication is provided, and controls the power supply of inductance type switch coil.
Charging output circuit charges the battery; Charging indication is subject to the control of charging detection control circuit, the operating state of indication charger (charge or charged), and corresponding indicator light is bright.

One, power supply is controlled (1) and is selected coil self-locking type switch:
When switch is pressed, two groups of closed chargers of normally opened contact obtain electric (22V), and the coil in mains switch is through feeding back electricly, and switch self-locking, charger are in to obtain electricity condition.220V power supply inputs to ac-dc converter circuit (2); Ac-dc converter circuit (2) by the alternating current of 220V through step-down, be rectified into low-voltage DC; Low-voltage DC detects control circuit (4) to charging output circuit (5) through electric current, the voltage of charging Circuit tuning (3) output certain value through charging; Electric current, voltage in the continual detection charging output circuit of charging detection control circuit (4) (5), when normal output, charging detects control circuit (4) and provides power supply to the coil in power supply control (1) and the charging indicator light in charging indication (6); When charging reaches set point, charging detects electric current, the Voltage-output that control circuit (4) cuts off charging output circuit (5), charging indicator light dead electricity in charging indication (6), coil in (1) part of power supply control is simultaneously dead electricity also, the normally opened contact of switch is separated, the whole 220V power supply that cuts off of charger.
Be not with self-locking inductance type switch because not needing mechanical self-locking device, do not need the indicating circuit that charged, easily manufactured, cost is low, but because of coil in charging process always electric, also need to consume some electric energy, energy-saving effect is not good enough.
Two, power supply is controlled (1) and is selected mechanical self-latching type inductance type switch:
When switch is pressed, switch self-locking, two groups of closed chargers of normally opened contact obtain electric (220V); 220V power supply inputs to ac-dc converter circuit (2); Ac-dc converter circuit (2) by the alternating current of 220V through step-down, be rectified into low-voltage DC; Low-voltage DC detects control circuit (4) to charging output circuit (5) through electric current, the voltage of charging Circuit tuning (3) output certain value through charging; Charging detects electric current, the voltage in the continual detection charging output circuit of control circuit (4) (5), when reaching set point, cut off electric current, the Voltage-output of charging output circuit (5), when charging, charging indicator light in charging indication (6) obtains electric (bright), and the coil that charged indicator light and power supply are controlled in (1) must not be electric; Charging indicator light dead electricity (going out) in charging indication while having charged (6), the indicator light that charged obtain electric (bright), simultaneously power supply control coil in (1) part also electric, the normally opened contact of switch is separated, the whole 220V power supply that cuts off of charger.
Self-locking inductance switch is because there being mechanical type self-locking device, and complex manufacturing, cost are high, but because not consuming energy in charging process, only after charging completes, in a period of time, consume energy, so relative energy-saving.
Owing to adopting, the charging control circuit of charging control circuit and existing charger is just the same, so improve also very simple to existing charger, only need on existing charger, carry out a small amount of change, in power line, increase an inductance type mains switch, according to the difference of inductance type switch (mechanical self-latching, inductance self-locking), the charging indication in the coil of switch and charging indicator light circuit or the indication of having charged is in parallel, according to the magnitude of voltage of the voltage of switch coil and charging indication, do corresponding change simultaneously
The utility model is simple in structure, and circuit performance is perfect, cost is low, economize energy environmental protection can use on a large scale.
