Description
Technical field
The utility model relates to field of data storage, more particularly to it is a kind of can display memory volume residual USB flash disk.
Background technique
A kind of electronic product with storage function on USB flash disk, since USB flash disk is small in size, capacity is big, reliable and stable to be convenient for taking
Band, obtains the welcome of vast computer user, but most USB flash disk on the market all only has storage function now, and because
Excessive or data category is too many for data, for the ease of management, people generally require to carry out data using multiple USB flash disks simultaneously to deposit
Storage, for the content stored in each USB flash disk of distinguishing one from the other, needs to be inserted into computer one by one and be checked, at one's side without electricity
In the case where brain, the data in USB flash disk just cannot be distinguished；Or the modes such as labelling do additional label on USB flash disk shell, and U
As mobile memory part, the interim storage and transfer, interior data for being mainly responsible for data can be changed frequently disk, this logical
It crosses in USB flash disk shell applying labels mode, though the purpose for distinguishing content in USB flash disk can be played, each more new data is also needed
Label substance is updated, it is cumbersome.
In order to solve this problem, Chinese patent (publication number: CN206147692U) discloses " a kind of with reading device
USB flash disk ", USB flash disk body surface be equipped with display screen, display screen bottom be equipped with battery, can be not inserted by the display screen
In the case where computer or mobile phone, the remaining size of USB flash disk interior storage space and the information of USB flash disk are shown by display screen.The reality
With the market competitiveness of Novel hoisting mobile device.But the type of display screen is not illustrated, why USB flash disk is by vast
The welcome of user, very big one the reason is that USB flash disk compact, under so small volume, further integrated battery and display
Screen, the capacity of battery can only be necessarily very small, and common display screen shows that content needs the support of backlight, and powers off
After cannot keep display information, need to check every time USB flash disk inner storag information require open power supply, cause power consumption larger, therefore
Above-mentioned USB flash disk in actual use, is frequently switched on, the display screen of the battery of low capacity and high energy consumption, inevitably results in and be detached from
In the case where external power supply, the displaying to data in USB flash disk and remaining space can only be realized within the very limited time, using it is upper still
It is so relatively complicated, it cannot thoroughly solve the problems, such as the identification of USB flash disk.
Utility model content
In order to overcome the drawbacks of the prior art, the technical problem to be solved by the utility model is to how to be not inserted into electricity
In the case where brain or mobile phone, the data of remaining space size and storage inside in long-term, effective identification USB flash disk.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
It is a kind of can display memory volume residual USB flash disk, comprising: USB flash disk ontology, microprocessor, display screen, built-in power and brush
New button, the microprocessor are used to read data, the free memory size of the calculating USB flash disk in the USB flash disk, provide described
The display content of display screen；The built-in power is used to mention when the USB flash disk is not inserted into computer for the microprocessor, display screen
For working power；The display screen is for showing information；The refresh button is used to update the display content of the display screen；
It is characterized in that,
The built-in power is electrically connected with the USB flash disk ontology, microprocessor and display screen respectively；
The refresh button is electrically connected with the microprocessor；
The microprocessor is electrically connected with the USB flash disk ontology；
The display screen is electronic ink screen.
Based on the above technical solution, the utility model can also do following improvement.
Preferably, the ink screen shows that content can be customized；
Preferably, the refresh button can control the ink screen display content in customized text, pattern and USB flash disk
Cyclic switching is carried out between free memory；
Preferably, the USB flash disk charges when being inserted into computer end USB port for built-in power；
Compared with prior art, the utility model has the following technical effect that
Show that data or free memory size, electronic ink screen exist in USB flash disk using the electronic ink screen of super low-power consumption
Still the image before power-off can be shown after power-off, and shows that the time was up to as long as half a year, the only ability power consumption when refreshing shows content
And power consumption, since the USB flash disk in general normal use was every several days, will necessarily be updated data at most several weeks down to 30mW,
Therefore above scheme can consider the identification thoroughly solved the problems, such as in USB flash disk routine use.
Detailed description of the invention
Fig. 1 be the utility model can display memory volume residual USB flash disk structural schematic diagram top view；
Fig. 2 be the utility model can display memory volume residual USB flash disk structural schematic diagram front view；
In the accompanying drawings, list of designations represented by each label is as follows:
1 --- USB flash disk ontology；
2 --- USB flash disk lid；
3 --- USB flash disk plug；
4 --- refresh button；
5 --- electronic ink screen；
6 --- built-in power；
7 --- microprocessor.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Please refer to shown in Fig. 1, be the utility model can display memory volume residual USB flash disk structural schematic diagram.One
Kind can display memory volume residual USB flash disk, comprising: USB flash disk ontology 1, USB flash disk lid 2, USB flash disk plug 3, microprocessor 7, display screen 5,
Built-in power 6 and refresh button 4, the microprocessor 7 be BCM 7583, by read the data in the USB flash disk ontology 1, based on
The free memory size for calculating the USB flash disk ontology 1 provides the display content of the display screen 5；The built-in power 6 is used in institute
It states and provides working power when USB flash disk ontology 1 is not inserted into computer for the microprocessor 7, display screen 5；The display screen 5 is for showing
Information；The refresh button 4 is used to update the display content of the display screen 5；The built-in power 6 respectively with the USB flash disk sheet
Body 1, microprocessor 7 and display screen 5 are electrically connected；The refresh button 4 is electrically connected with the microprocessor 7；The microprocessor 7
It is electrically connected with the USB flash disk ontology 1；The display screen 5 is electronic ink screen, and the content that the display screen 5 is shown can be customized
Setting；The refresh button 4 can control the content of the display of display screen 5 in customized text, pattern and USB flash disk residue
Cyclic switching is carried out between depositing；The USB flash disk ontology 1 charges when being inserted into computer end USB port for built-in power 6；
When by the USB flash disk ontology 1 be inserted into computer after, can computer end it is customized setting display screen 5 content, such as
The name of owner or the description of storage content etc. are equivalent to the data label that electronic edition is provided with to the USB flash disk；
When detecting that refresh button 4 is pressed, the built-in power 6 is the microprocessor 7, USB flash disk ontology 1 and display
5 power supply of screen, the microprocessor 7 are that the display screen 5 provides new display content, the display content customized text,
