Abstract
The utility model discloses a kind of charger of automatic adjustment power output, comprise the charger body with pin and to be connected with charger body by wire and for the output termination of connecting circuit, the shell that described charger body comprises drain pan and coordinates with drain pan, surface-mounted integrated circuit is provided with in described drain pan, described surface-mounted integrated circuit is provided with capacitor, filter, transformer and power tube, is provided with thermistor between described transformer and power tube.Its advantage is: between power tube and transformer, install thermistor additional, internal temperature and ambient temperature are detected in real time, when temperature height being detected, after thermistor resistance diminishes and passes to integrated circuit identification, adjust and its power output is reduced, thus charger temperature is declined.After equitemperature gets off, when thermistor detects that temperature is low, feed back to integrated circuit, thus power starts to promote, and so repeatedly carries out, thus protection charger.
Description
Technical field
The utility model relates to a kind of charger, is specifically a kind of charger of automatic adjustment power output.
Background technology
Charger is a kind of equipment alternating current being converted to low-voltage DC.Charger is of many uses in every field, is particularly widely used in the common electrical equipment of mobile phone, camera etc. at sphere of life.Charger adopts power electronics semiconductor device, is galvanic a kind of static ac dc converter device by voltage and the changeless convert alternating current of frequency.
In use can there is following problem in current general charger: when by rechargable battery power shortage is serious or ambient temperature is too high time, charger can be burnt when charger charges the battery, even can explode time serious, cause causing fire, the useful life of charger is low.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: a kind of long service life is provided and safety the charger of automatic adjustment power output.
Technical solution of the present utility model is: a kind of charger of automatic adjustment power output, comprise the charger body with pin and to be connected with charger body by wire and for the output termination of connecting circuit, the shell that described charger body comprises drain pan and coordinates with drain pan, surface-mounted integrated circuit is provided with in described drain pan, described surface-mounted integrated circuit is provided with capacitor, filter, transformer and power tube, is provided with thermistor between described transformer and power tube.
Further, described surface-mounted integrated circuit is also provided with the first electric capacity, the second electric capacity, the 3rd electric capacity and the 4th electric capacity.
Further, described pin is two pin or three pins.
Apply the charger of a kind of automatic adjustment power output provided by the utility model, its beneficial effect is: between power tube and transformer, install thermistor additional, internal temperature and ambient temperature are detected, when temperature height being detected, thermistor resistance diminishes and passes to integrated circuit, its power output is reduced, thus charger temperature is declined.After equitemperature gets off, when thermistor detects that temperature is low, feed back to integrated circuit, thus power starts to promote, and so repeatedly carries out, thus protection charger.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is partial exploded view of the present utility model.
Shown in figure: 1-charger body, 1.1-pin, 1.2-drain pan, 1.3-shell, 2-exports termination, 3-surface-mounted integrated circuit, 4-capacitor, 5-filter, 6-transformer, 7-power tube, 8-thermistor, 9-first electric capacity, 10-second electric capacity, 11-the 3rd electric capacity, 12-the 4th electric capacity.
Embodiment
For more intuitively, intactly understanding the technical solution of the utility model, existing just to carry out nonrestrictive feature description in conjunction with the utility model accompanying drawing as follows:
As depicted in figs. 1 and 2, a kind of charger of automatic adjustment power output, comprise the charger body 1 with pin 1.1 and to be connected with charger body 1 by wire and for the output termination 2 of connecting circuit, the shell 1.3 that charger body 1 comprises drain pan 1.2 and coordinates with drain pan 1.2, surface-mounted integrated circuit 3 is provided with in drain pan 1.2, surface-mounted integrated circuit 3 is provided with capacitor 4, filter 5, transformer 6 and power tube 7, is provided with thermistor 8 between transformer 6 and power tube 7.Surface-mounted integrated circuit 3 is also provided with the first electric capacity 9, second electric capacity 10, the 3rd electric capacity 11 and the 4th electric capacity 12, and the capacity of the first electric capacity 9, second electric capacity 10, the 3rd electric capacity 11 and the 4th electric capacity 12 is all unequal, surface-mounted integrated circuit 3 is also provided with the elements such as all kinds of matching used resistance, diode.
Pin 1.1 is two pin or three pins, and the convenient socket of different model that coordinates uses.
The charger of a kind of automatic adjustment power output provided by the utility model, thermistor 8 is installed additional between power tube 7 and transformer 6, internal temperature and ambient temperature are detected, when temperature height being detected, thermistor 8 resistance diminishes and passes to integrated circuit, its power output is reduced, thus charger temperature is declined.After equitemperature gets off, when thermistor 8 detects that temperature is low, feed back to integrated circuit, thus power starts to promote, and so repeatedly carries out, thus protection charger.And the cost installing hot name resistance additional is not high, but promote very large to actual safe effect.
Certainly; these are only preferred embodiment of the present utility model; non-ly therefore namely limit to the scope of the claims of the present utility model, all utilization the utility model specifications and graphic content institute be simple and easy modification and equivalent structure change for it, all should in like manner be contained within scope of patent protection of the present utility model.
