Abstract
A universal charger for flashlight, battery of mobile phone, adopts simple circuit structure composition.Charger has charging indication function, and when when the work of charging, red indicator light is bright, represents battery in charging; When battery is full of electricity, white indicating light is bright, represents that battery is full of electricity, automatically stops the charging to battery, prevents overcharge.
Description
Technical field
The utility model relates to the universal charger of a kind of flashlight, battery of mobile phone.
Background technology
The utilization rate of flashlight, mobile phone reaches popularity, charger as flashlight, battery of mobile phone is all adopt charger flashlight, the battery of mobile phone of pulse transformer composition to charge, circuit is comparatively complicated, during use, spoilage is high, is again that maintenance just can will be repaired by professional and technical personnel.
Summary of the invention
The universal charger of a kind of flashlight of the utility model, battery of mobile phone, adopts simple circuit structure, constant charging current, and automatically can stop charging when being full of electricity, prevents overcharge and damages battery.
A universal charger for flashlight, battery of mobile phone, outward appearance continues to use the original charger case of flashlight, battery of mobile phone, and charger has two pins, and during charging, the jack inserting supply socket connects input power; Export and have to be with a plug for positive and negative electrode, can charge in charging jacks plug being inserted in flashlight or mobile phone.
A universal charger for flashlight, battery of mobile phone, circuit structure is made up of capacitance-resistance voltage reduction circuit, rectification circuit, voltage stabilizing circuit and charging Warning Mark circuit.
Accompanying drawing explanation
Accompanying drawing is the circuit theory diagrams of universal charger of a kind of flashlight, battery of mobile phone.
Embodiment
As shown in drawings, R, C form capacitance-resistance voltage reduction circuit, and alternating current 220V voltage is reduced to about 4V alternating current, send to rectifier and carry out rectification.Described rectifier B is single-phase full wave rectifier, and its input is alternating current, and output is the direct current of pulsation.
As shown in drawings, D2 is two ends pressurizers, selects voltage stabilizing value to be 3.7V, and when charger is when charging, D2 ends; D1, D3 are light-emitting diode displays, and be charging Warning Mark circuit, select D3 to be red color, D1 is white colour, selects the light-emitting diode display being with double-colored function.During charger operation, when not reached 3.7V by charged battery voltage, D2 ends, and D1 does not work, and the D3 of redness is bright, represents battery in charging; When battery E is filled 3.7V, D2 then becomes conducting from cut-off, and LED refers to that display becomes white from redness, and namely D1 is bright, and D2 does not work, and represents that battery is full of electricity.
