Abstract
The utility model discloses an energy-saving environment-friendly mobile phone charger. The energy-saving environment-friendly mobile phone charger comprises a shell (2), a copper plug (1) which is connected with the shell (2) and one end of which extends out of the shell (2), a USB (Universal Serial Bus) port (3) which is formed on the outer side surface of the shell, and a circuit board (4) which is arranged inside the shell (2), wherein a rectification module (5), a transformer assembly (6), a battery voltage detecting device (7) and a cut-off switch (8) are integrated on the circuit board (4); the rectification module (5) converts alternating current to direct current; the transformer assembly (6) converts high voltage to low voltage; and when the battery voltage detecting device (7) detects that voltage of a rechargeable battery reaches a rated voltage, a signal is sent to control the cut-off switch (8) to cut off power. The battery voltage detecting device and the cut-off switch are integrated on the circuit board, so that power can be cut off after the battery is fully charged, thereby achieving a good energy-saving effect and prolonging the service life of the battery.
Description
Technical field
The utility model relates to a kind of charger, is specifically related to a kind of energy saving and environment friendly charger for mobile phone.
Background technology
Popularizing of existing mobile phone, charger for mobile phone is the thing of the indispensability of every money mobile phone, he has advantages of with using with filling, need not pull down the trouble that battery uses seat to fill, but present charger will be pulled up cumbersome from supply socket after having rushed electricity, along with the quickening of modern's rhythm of life, all charger is not pulled up above socket in order to save trouble, according to related news, the electric energy that the whole nation is wasted because charger for mobile phone does not pull up above charger is about 2,000,000 degree, and its radiation producing simultaneously affects the healthy of people too.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of energy saving and environment friendly charger for mobile phone, and it can be after charging mobile phone battery completes, auto-breaking.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows: a kind of energy saving and environment friendly charger for mobile phone, comprise housing (2), be connected with housing (2) and the copper plug (1) of described housing (2) is stretched out in one end, be located at the USB socket (3) of described hull outside face, be located at the inner circuit board (4) of described housing (2), on described circuit board (4), be integrated with rectification module (5), transformer device (6), battery voltage detector (7), cut-off switch (8), described rectification module (5) changes alternating current into direct current, high pressure is transformed into low pressure by described transformer device (6), described battery voltage detector (7) sends signal controlling cut-off switch (8) power-off while detecting charged battery voltage to rated voltage.
As preferably, described copper plug (1) comprises 2 or 3 pins.
(3) beneficial effect
The utility model is compared to prior art; it has following beneficial effect: owing to being integrated with battery voltage detector and cut-off switch on circuit board; can be after battery have charged auto-breaking; play good energy-saving effect; protect battery can not be in for a long time charged state simultaneously; extend battery, and the utility model is simple in structure, novel in design, easily manufactured, energy-conserving and environment-protective, has practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of energy saving and environment friendly charger for mobile phone of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The energy saving and environment friendly charger for mobile phone of one as shown in Figure 1, comprise housing 2, be connected with housing 2 and one end stretch out housing 2 copper plug 1, be located at hull outside face USB socket 3, be located at the circuit board 4 of housing 2 inside, on circuit board 4, be integrated with rectification module 5, transformer device 6, battery voltage detector 7, cut-off switch 8, rectification module 5 changes alternating current into direct current, high pressure is transformed into low pressure by transformer device 6, and battery voltage detector 7 sends signal controlling cut-off switch 8 power-off while detecting charged battery voltage to rated voltage.Copper plug 1 comprises 2 or 3 pins.
Due in the time charging; the voltage of battery can raise gradually; there is respective change in electric current, after charging completes, battery voltage value will be stabilized in specified scope thereupon; at this moment the battery voltage detector in charger detects after voltage stabilization; can send signal and carry out control circuit auto-breaking, thereby play energy-conserving action, but also can protect battery; extend battery, can not cause over-charging of battery.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
