Technical field
The utility model relates to a kind of charger, especially a kind of new-type universal charger.
Background technology
Charger typically refers to the equipment that alternating current is converted into low-voltage DC.Charger is of many uses in every field, particularly is widely used in the common electrical equipment of mobile phone, camera or the like at sphere of life.Charger is to adopt power electronics semiconductor device, and voltage and the constant alternating current of fixed-frequency are transformed to galvanic a kind of static ac dc converter device.In the electricity consumption occasion that with the storage battery is working power or stand-by power supply, charger is with a wide range of applications.
Social now, various electrical appliances appear at people at the moment, and charger is matching used with electrical appliance, and electrical appliance needs charging; Just need charger, charger is made up of charging device, shell, lead etc., and volume is little, and is easy to carry; But a drawback is arranged, and present electrical appliance basically all is two batteries, needs to give simultaneously two battery charge sometimes; And existing charger can only satisfy the charging of a battery, is exactly in addition, and now people charge to electrical appliance, electrical appliance rush to electricity just no matter; Do not know how long can be full of electricity yet, charging so always, the waste electric energy is also to producing certain influence in useful life of battery.
The utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of the utility model is to provide a kind of new-type universal charger; It is employed in charger set inside voltage regulator, time regulator and auto-power-off device.
For the technical scheme that purpose adopted that realizes the utility model is: a kind of new-type universal charger is characterized in that: it is made up of shell, switch, USB interface, voltage regulator, time regulator, auto-power-off device, charging device, contact button, control circuit, voltage stabilizing circuit; Described shell is a square body; The upper end is provided with groove, contact button, indicator light and switch, and inside is provided with chip, charging device, voltage regulator, time regulator, auto-power-off device, and the left side is provided with knob; The right side is provided with time button and automatic switch, and the lower end is provided with USB interface; Described groove is a square shape, and inside is provided with contact, pressing plate and spring; Described control circuit is made up of resistance R 2, chip IC, relay J, K switch and buffer W; Described voltage stabilizing circuit is made up of bleeder resistance R1, electric capacity of voltage regulation C1, rectifier diode VD, filter capacitor C2, voltage stabilizing didoe ZD.
The beneficial effect of the utility model is: it can charge to electrical appliance, can select the length in charging interval again, can also cut off the power supply automatically, and after the electrical appliance charging finished, auto-power-off device was cut off the electricity supply automatically, and charging stops; And simple in structure, economical and practical, be widely used in huge numbers of families.
