Abstract
The utility model relates to a charger, comprising a shell body, a voltage division rectification circuit, a quick charging switch, a charging indication lamp, a battery holder and an attaching plug. The charger adopts a capacitance voltage division rectification circuit; a transformer element with easy heating and large electric power consumption is economized; the utility model has the advantages that the electricity energy can be saved, long time use doesn't generates heat, the power factor of the electric inductive network can be raised, etc. The utility model has simple structure, small size and low cost.
Description
The utility model is a kind of charger.
The present charger of using, all adopt transformer that the alternating current 220V power source transition is become low-voltage after, obtain charge power supply through rectification circuit again.Because the charging interval is longer, charger easily generates heat, and power consumption is big, and general power supply grid inductive load is more, and existing charger voltage drop element transformer also is an inductive element, thus can reduce the power factor of electrical network, and complex structure, volume is big, and cost is higher.
At the problem that prior art exists, the purpose of this utility model is that design is a kind of simple in structure, and cost is low, economize on electricity, athermic capacity load charger.
The utility model is by housing (13), divides voltage rectifier plate (12), and battery tray (4) and attaching plug (11) constitute.Dividing potential drop electric capacity (3), quick charge electric capacity (1), rectifier diode (5), discharge diode (10), voltage-stabiliser tube (9), divider resistance (7) and charging indicator light (6) have been welded on minute voltage rectifier plate (12).One end of dividing potential drop electric capacity (3) and the live wire of power supply join, and the other end links to each other with the rectifier diode (5) of series aiding connection and the node of discharge diode (10).The other end of discharge diode (10) and the ground wire of power supply join.The two ends of voltage-stabiliser tube (9) link to each other with the other end homopolarity of rectifier diode (5) with discharge diode (10) respectively.Divider resistance (7) is connected with rechargeable battery (8) with charging indicator light (6) back in parallel, is connected to the two ends of voltage-stabiliser tube (9) again.Quick charge electric capacity (1) connect with fast charge switch (2) back and dividing potential drop electric capacity (3) and connecing by the break-make of fast charge switch (2) control quick charge electric capacity (1), are realized the conversion of quick charge and normal charge.Divide voltage rectifier plate (12), battery tray (4) and fast charge switch (2) to be installed on the housing (13).
Described embodiment is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
Accompanying drawing 2 is a structure diagram of the present utility model.
Present embodiment is by housing (13), divides voltage rectifier plate (12), and battery tray (4) and attaching plug (11) constitute.Dividing potential drop electric capacity (3), quick charge electric capacity (1), rectifier diode (5), discharge diode (10), voltage-stabiliser tube (9), divider resistance (7) and charging indicator light (6) have been welded on minute voltage rectifier plate (12).Divide voltage rectifier plate (12), battery tray (4) and fast charge switch (2) to be installed on the housing (13).This charger is by the power supply of alternating current 220V power supply, and an end of the live wire of power supply and dividing potential drop electric capacity (3) joins, and after dividing potential drop electric capacity (3) dividing potential drop, provides half-wave pulsating direct current charging current by rectifier diode (5) rectification to rechargeable battery (8).The half-wave in addition of AC power is got back to power supply through discharge diode (10), makes dividing potential drop electric capacity (3) discharge.The rated voltage and the electric current of voltage-stabiliser tube (9) should be higher than charging voltage and electric current.Rechargeable battery (8) is parallel to the two ends of voltage-stabiliser tube (9) with after divider resistance (7) is connected.Divider resistance (7) provides voltage for charging indicator light (6), and when battery charge, charging indicator light (6) is luminous.Because the reverse-conducting voltage of voltage-stabiliser tube (9) is higher than charging voltage, when charging, not conducting of voltage-stabiliser tube (9), charging voltage increases with the voltage rising of rechargeable battery, and it is constant to remain charging current.The size of charging current is decided by the capacity of dividing potential drop electric capacity, and when fast charge switch (2) was closed, quick charge electric capacity (1) was parallel on the dividing potential drop electric capacity (3), has increased the capacity of dividing potential drop electric capacity, thereby charging current is increased, and realizes quick charge.
This charger is a capacitive circuit, can improve the power factor of inductive electrical network during use, has saved the transformer element of easy heating, and long-time charging is not generated heat, and power consumption is little, energy saving, and simple in structure, volume is little, and cost is low.Have significant social and economic benefit.
