Abstract

A general charger for a flashlight and a mobile phone battery is formed by simple circuit structures. The charger has a charging indicting function; a red indicating lamp is on when the charger operates, which shows the battery is charged; a white indicating lamp is lighted when the battery is fully charged, which shows that the battery is fully charged, charging of the battery is automatically stopped, and overcharging is prevented.

Description

The universal charger of a kind of flashlight, battery of mobile phone
Technical field
The present invention relates to the universal charger of a kind of flashlight, battery of mobile phone.
Background technology
The utilization rate of flashlight, mobile phone has reached popularity, charger as flashlight, battery of mobile phone is all that the charger that adopts pulse transformer to form charges to flashlight, battery of mobile phone, circuit is comparatively complicated, during use, spoilage is high, is again that maintenance will just can be repaired by professional and technical personnel.
Summary of the invention
The universal charger of a kind of flashlight of the present invention, battery of mobile phone, adopts simple circuit structure, and constant charging current, and can automatically stop charging while being full of electricity prevents from overcharging and damages battery.
A universal charger for flashlight, battery of mobile phone, outward appearance is continued to use flashlight, the original charger case of battery of mobile phone, and charger has two pins, and during charging, the jack that inserts supply socket connects input power; Output has one with the plug of positive and negative electrode, plug is inserted in the charging jack of flashlight or mobile phone and can charges.
A universal charger for flashlight, battery of mobile phone, circuit structure is by capacitance-resistance voltage reduction circuit, rectification circuit, voltage stabilizing circuit and charging Warning Mark the electric circuit constitute.
Accompanying drawing explanation
Accompanying drawing is the circuit theory diagrams of the universal charger of a kind of flashlight, battery of mobile phone.
Embodiment
As shown in drawings, R, C form capacitance-resistance voltage reduction circuit, alternating current 220V lower voltage, are 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, and selecting voltage stabilizing value is 3.7V, when charger is when charging, and D2 cut-off; D1, D3 are light-emitting diode displays, are charging Warning Mark circuit, and selecting D3 is red color, and D1 is white colour, selects the light-emitting diode display with double-colored function.Charger when work, when being recharged cell voltage and not reaching 3.7V, D2 cut-off, D1 does not work, and red D3 is bright, represents that battery is in charging; When battery E is filled 3.7V, D2 becomes conducting from cut-off, and LED refers to that display becomes white from redness, and D1 is bright, and D2 does not work, and represents that battery has been full of electricity.
