Description
Technical field
The utility model relates to charger field more particularly to a kind of charger is automatically powered off with digital display.
Background technique
Mobile electronic device has been widely used for the various aspects of people's life at present, greatly facilitates going out for people
Row, also quickly, full a whole day can not be used by being filled with electricity sometimes toward contact for electronic equipment power consumption, and charger is needed frequently to charge.
But existing charger does not have automatic circuit break function, no matter whether the battery of electronic equipment has been filled with electricity, as long as not manually
Light source of charger is cut off, charger will continue to charge the battery, this not only causes the waste of the energy, can also be to electronic equipment
Battery damage, if the charging time it is too long cause battery temperature excessively high, the possibility exploded also is had, to personal safety
Cause very big hidden danger.
Utility model content
Charger is automatically powered off with digital display the technical problem to be solved by the present invention is to provide a kind of, is electronic equipment
It can be automatically powered off after fully charged, it is highly-safe.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows: a kind of to automatically power off charging with digital display
Device, including shell are provided with circuit board in the shell, are provided on the shell and insert with the power supply of the circuit board electrical connection
Head, USB interface, LCD display, Current Voltage switch key, the circuit board include automatically powering off module, mobile phone charging module,
The Current Voltage switch key is connect through red, green light emitting diode with LCD display.
As a preferred embodiment of the present invention, the circuit board is additionally provided with timing module and voice cue module, institute
It states and is provided with timing button and buzzer on shell.
As a preferred embodiment of the present invention, the shape of the shell is cuboid, cylinder or cylindroid.
As a preferred embodiment of the present invention, the shell is cylindrical or rectangular, surface be covered with one layer it is scratch resistant
Protective film, the shell are white plastic shell.
Beneficial effect by adopting the above technical scheme is: circuit board, which is provided with, automatically powers off module, when charger is electronics
When product is fully charged, charger, which can automatically power off to prevent from overcharging electronic product, damages its battery, also avoids temperature is excessively high from causing
Fire occurs；When charger is when for electronic product charging, real-time current, the voltage of charger can be shown on LCD display,
It enables users to further confirm that charger is that electronic product is filled with electricity.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
In figure, 1- shell, 2- attaching plug, 3-USB interface, 4- Current Voltage switch key, 5-LCD display screen, 6- buzzing
Device, 7- timing button.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is a kind of to automatically power off charger, including shell 1 with digital display referring to attached drawing, circuit board, shell are provided in shell 1
It is provided on body 1 and the attaching plug 2 of circuit board electrical connection, USB interface 3, LCD display 5, Current Voltage switch key 4, circuit
Plate includes automatically powering off module, mobile phone charging module, and Current Voltage switch key 4 is through red, green light emitting diode and LCD display 5
Connection.
The module that automatically powers off of the utility model is early to be widely used to every field, but this technology is not usually
Very stable, once out of joint, charger is that will not automatically power off after electronic product is fully charged, user's also inconvenient discovery in time
Whether electronic product is fully charged, what security risk still may occur；This product propose Current Voltage switch key 4 through it is red,
Green light emitting diode is connect with LCD display 5, and the other end of red, green light emitting diode is connect with circuit board, can be shown in LCD
Real-time current and voltage of the charger in charging are shown on screen 5, corresponding red diode is electric current, and green diode is corresponding
Be that voltage is shown on LCD display 5 and individually shows, it on LCD display 5 is aobvious that Current Voltage switch key 4, which is for switching,
Show electric current registration or voltage readings, normally in charging, the electric current of display is 1.5-2A or so, and voltage is 5V or so, works as electronics
When product charging complete, the meeting automatic extinguishing screen of LCD display 5, charger has been automatically powered off at this time.The plug of power supply can be both feet
Plug is also possible to trigonometric expression plug, this does not all influence the display of voltage and current.
Circuit board is additionally provided with timing module and voice cue module, and timing button 7 and buzzer 6 are provided on shell 1.
It is the electricity that electronic product fills setting time that timing button 7, which can control charger, and the time point to setting will automatically power off, and is used
Family operation timing button 7 shows the time on LCD display 5, convenient for the user to operate；Buzzer 6 is connect with circuit board, due to electricity
Road plate is equipped with voice cue module, and when electronic product is fully charged, when automatic power-off function of charger can buzzer 6 make a sound to mention
Wake up user, then is avoided in big degree due to overcharging initiation fire, and safety is higher.
The shape of shell 1 is cuboid, cylinder or cylindroid.This is three kinds of most common shapes, can be according to user's
Hobby designs different shapes, does not affect function.
The surface of shell 1 is covered with one layer of scratch resistant protective film, and shell 1 is white plastic shell.Scratch resistant protective film be in order to
Prevent protection charger scratched and protected inside circuit board, plastic shell light quality is easy to use.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
