Embodiment
As shown in Figure 2, when charger host switch SW places " A " shelves, after supporting voltage adapter becomes the 6V direct current with alternating current 220V civil power or automobile storage battery 12V voltage transformation, be connected with the charger main frame through plug, send into mobile phone after the current-limiting resistance current limliting by the charger main frame and give charging mobile phone battery.Because of adopting constant-voltage charge, maximum charging current is limited in below the 400mA, rising along with battery of mobile phone voltage, charging current reduces gradually, when battery of mobile phone is filled, the charging control circuit of mobile phone inside disconnects, and charging finishes, and this process needs 2～3 hours (different and different with the battery of mobile phone capacity) approximately.
When charger host switch SW places " B " shelves, the charger main frame can be separately to charging mobile phone battery, the inner alkaline dry battery of installing of charger main frame or the electric current of rechargeable battery flow through current relay J1, and after the current-limiting resistance current limliting, send into mobile phone and give charging mobile phone battery, automatically detect the size of charging current simultaneously, if this moment, electric current was greater than 200mA, relay J 2 adhesives, the DC/DC translation circuit is not worked, when charging current during less than 130mA, after 20 seconds, relay J 2 contacts discharge, the DC/DC translation circuit is stabilized in charging voltage 5V and continues charging through current limliting to battery of mobile phone, battery of mobile phone can be full of after about 2.5 hours, and charging finishes.
As Fig. 2, shown in Figure 3, when charger host switch SW places " C " shelves, the charger main frame will not worked.At this moment (general dry battery is forbidden charging as charging to the inner rechargeable battery of installing of charger main frame by plug connection charger main frame with supporting voltage adapter or solar panel! ), because of adopting constant-voltage charge, so the charging interval is not had strict restriction, the suggestion charging interval get final product less than 12 hours greater than 4 hours, in order at any time to charging mobile phone battery.
This charger can be connected with mobile phone to be charged by changing different output charging plugs, can carry out battery charge to the arbitrary brand mobile phone that uses nominal voltage 3.6V or 3.7V etc., owing to adopt constant-voltage charge, and the DC/DC circuit adopts the special-purpose integrated package of power supply to form, so can not produce any hidden danger to mobile phone.
The various operating states of LED 1-LED4 indication charger main frame.
When using this charger main frame " B " shelves to give charging mobile phone battery, bright (the inner alkaline dry battery electric weight of its expression charger abundance of LED1 (green), little bright expression electric weight deficiency, extinguish expression and do not had electric weight), LED3 is (red simultaneously, green double-colored) also bright, when sending green light, it represents that charging current is greater than 200MA at this moment, when sending orange-colored light, it represents that inner DC/DC circuit works, provide charging current by DC/DC, when the little flicker of LED3, the expression battery of mobile phone is filled substantially, show that on mobile phone battery is filled, can stop charging mobile phone.
When LED2 (red) is bright, charger main frame inside buzzer HTD pipes simultaneously, and inner alkaline dry battery of installing of expression charger main frame or electric quantity of rechargeable battery are not enough, and as the inside use is rechargeable battery, then should stop cell-phone charging, to avoid the rechargeable battery over-discharge can.As the inside use is common alkaline dry battery, then can not add and show interest in, extinguish until LED2, when buzzer stops ringing, stop charging mobile phone battery being got final product, and take out alkaline dry battery simultaneously, the essentially no electric weight of alkaline general dry battery of this moment has been changed to battery of mobile phone, not by full charge, the alkaline dry battery that can more renew continues to charging mobile phone battery as battery of mobile phone.
LED4 (green) is bright, and LED3 is bright to be illustrated in voltage adapter or solar panel charging mobile phone battery.
LED4 is bright, is illustrated in working voltage adapter or solar panel to the inner rechargeable battery charging of installing of charger main frame.
LED5 is the special-purpose purple light pipe of currency examine, does currency examine and uses.
LED6 is the white luminous pipe of high brightness, makees illuminating lamp and uses.
