Description
Technical field
The present invention relates to a kind of charging circuit, particularly make things convenient for a kind of multifunctional mobile phone charger of out on tours.
Background technology
Existing a kind of charger that passes through four batteries to cell-phone charging because number of batteries is too many, adopts general alkaline battery can only though made things convenient for the user, bring environmental issue with once, the waste resource; Then quantity is many to adopt rechargeable battery, the cost height.
Summary of the invention
The purpose of this invention is to provide low, the environmental protection of a kind of cost, do not waste a kind of multifunctional mobile phone charger of resource.
The object of the present invention is achieved like this, multifunctional mobile phone charger, comprise a batteries storehouse in housing, the housing, it is characterized in that: the housing internal fixation has DC/DC booster circuit plate, the input of DC/DC booster circuit plate is electrically connected with the positive and negative electrode in a batteries storehouse, and the power output end of DC/DC booster circuit plate connects with the counter electrode of battery cathode with USB power interface seat and is electrically connected; One batteries converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current; Between the power end of DC/DC booster circuit and battery output K switch 1 is arranged, be serially connected with K switch 2 and charging circuit at the power end and the battery output of USB power interface seat, K switch 1 and K switch 1 are toggle switchs; The K1 of toggle switch closes, and K2 disconnects the road.
Described charging circuit charging voltage is 1.2V.
Described DC/DC booster circuit plate input voltage is 1-6V, and its output voltage is at 5.5-4.5 V.
Be serially connected with the luminous tube circuit between described DC/DC booster circuit plate output and the USB power interface seat.
Advantage of the present invention is: it is by batteries power supply, and a batteries converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current.Rechargeable battery quantity is few like this, and cost is low.Because a batteries is when DC/DC is transformed into 5V, its output current is along with the prolongation in charging interval, and its electric current also can diminish, and reaches because the voltage of load this moment rises, low the stirring that the input cell voltage brings that disappeared.Battery has toggle switch to the DC/DC circuit loop in addition, toggle switch forms K switch 1 and K2, the K1 of toggle switch closes, disconnect by K2, by be electrically connected the input of a 1.2V charging circuit at the power positive end interface of USB translation interface, 1.5V the charging circuit negative terminal is electrically connected with the K2 of toggle switch, can not only realize cell-phone charging like this, also can realize charging to a batteries.The rechargeable battery storehouse can adapt to No. 7 and No. 5 rechargeable batteries.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing:
Embodiment of the invention structural representation on Fig. 1;
Fig. 2 is an embodiment of the invention circuit theory diagrams.
Among the figure, 1, housing; 2, battery compartment; 3, positive electrode; 4, negative electrode; 5, indicator light; 6, DC/DC booster circuit plate; 7, USB power interface seat; 8, a batteries; 9, mobile phone; 10, conversion line; 11, toggle switch; 12, charging circuit.
Embodiment
As shown in Figure 1, multifunctional mobile phone charger, comprise a batteries storehouse 2 in housing 1, the housing, housing 1 internal fixation has DC/DC booster circuit plate 6, the input of DC/DC booster circuit plate 6 is connected with the positive electrode 3 in a batteries storehouse 2, negative electrode 4, and the power output end of DC/DC booster circuit plate 6 connects with the counter electrode of battery cathode with USB power interface seat 7 and is electrically connected; One batteries 8 converts the monocell of 1-1.5V to 5V voltage by the DC/DC circuit and offers the USB translation interface with constant current; Between the power end of DC/DC booster circuit and battery output K switch 1 is arranged, be serially connected with K switch 2 and charging circuit 12 at the power end and the battery output of USB power interface seat, K switch 1 and K switch 2 are toggle switchs 11; The K1 of toggle switch 11 closes, and K2 disconnects the road.
When mobile phone 9 connects the USB translation interface by conversion line 10, be charging process, indicator light 5 is bright.Conversion line 10 can be various hands with the standard handovers line of charging usefulness.The K1 of toggle switch closes, disconnected by K2, by be electrically connected the input of a 1.2V charging circuit at the power positive end interface of USB translation interface, 1.5V charging circuit negative terminal is electrically connected with the K2 of toggle switch, can not only realize cell-phone charging like this, also can realize charging to a batteries.The rechargeable battery storehouse can adapt to No. 7 and No. 5 rechargeable batteries.
