Abstract

The utility model discloses an energy-saving mobile phone charger. The energy-saving 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 rectifier 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 rectifier module (5) converts alternating current into direct current; the transformer assembly (6) converts high voltage into low voltage; and when the battery voltage detecting device (7) detects voltage of a rechargeable battery to reach 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

Energy-saving mobile phone charger
Technical field
The utility model relates to a kind of charger, is specifically related to a kind of energy-saving mobile phone charger.
Background technology
Popularizing of existing mobile phone, charger for mobile phone is the thing of the indispensability of every money mobile phone, he has with using with the advantage of 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, quickening along with 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 simultaneously its radiation that produces affects the healthy of people too.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of energy-saving mobile phone charger, and it can be after charging mobile phone battery be finished, 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 mobile phone charger, comprise housing (2), link to each other with housing (2) and an end stretches out the copper plug (1) of described housing (2), be located at the USB socket (3) of described hull outside face, be located at the inner circuit board (4) of described housing (2), be integrated with rectification module (5) on the described circuit board (4), transformer device (6), battery voltage detector (7), cut-off switch (8), described rectification module (5) changes alternating current into direct current, described transformer device (6) is transformed into low pressure with high pressure, and described battery voltage detector (7) sends a signal controlling cut-off switch (8) outage when 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 be integrated with battery voltage detector and cut-off switch at circuit board; can be after battery charging be finished auto-breaking; play good energy-saving effect; protect simultaneously battery can not be in for a long time charged state; prolong battery, and the utility model is simple in structure, novel in design, easily manufactured, has practicality.
Description of drawings
Fig. 1 is the structural representation of energy-saving mobile phone charger 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 explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of energy-saving mobile phone charger as shown in Figure 1, comprise housing 2, link to each other with housing 2 and an end stretch out housing 2 copper plug 1, be located at the hull outside face USB socket 3, be located at the circuit board 4 of housing 2 inside, be integrated with rectification module 5, transformer device 6, battery voltage detector 7, cut-off switch 8 on the circuit board 4, rectification module 5 changes alternating current into direct current, transformer device 6 is transformed into low pressure with high pressure, and battery voltage detector 7 sends a signal controlling cut-off switch 8 and cuts off the power supply when detecting charged battery voltage to rated voltage.Copper plug 1 comprises 2 or 3 pins.
Because when charging; the voltage of battery can raise gradually; respective change occurs in electric current thereupon, and after charging is finished, battery voltage value will be stabilized in the specified scope; at this moment after the battery voltage detector in the charger detects voltage stabilization; can send signal and come the control circuit auto-breaking, thereby play energy-conserving action, but also can protect battery; prolong battery, can not cause over-charging of battery.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from 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.
