Abstract
The invention discloses a kind of myopia prevention prompting device, can solve the problems, such as that the prolonged close eye of child easily causes eye damage.The lower pod body being rotatably connected including upper pod body, with upper pod body by spring, microprocessor, controller, the distance detector being connected with microprocessor are provided with the upper pod body, the input port connection microprocessor of the controller, an output port of the controller are connected at the micro projector of folder housing forward end.When distance detector detects that the eye distance books of child, the distance of display screen do not meet preset value, micro projector will be projected out pattern to prompt after being connected to signal in face of child, child will adjust sitting posture after seeing prompting pattern, automatically eyes are avoided into damage of the close eye to eye away from books or display screen；In addition, myopia prevention prompting device can conveniently be securely fixed in books or display screen side edge, it is easy to use, simple to operate.
Description
【Technical field】
The present invention relates to electronics field, more particularly to a kind of myopia prevention prompting device.
【Background technology】
The eyes are the windows of the mind, possesses the hope that the bright double pupils of a pair of are many people.However, current present situation is but
It is increasingly to carry out children's wearing to have played spectacles.According to education department《National myopia preventing and treating job posting》Statistics, China
Adolescent student, the rate of myopia of children have occupied second place of the world, and pupil's rate of myopia is 28%, and junior school student's rate of myopia is 60%,
High school student's rate of myopia is 85%, and university student's rate of myopia is 90%, large-scale myopia population, not only becomes the one of puzzlement parent
Individual problem, it also result in the great attention of government department and various circles of society.
It is bad with eye custom that the reason for domestic and international expert's research shows, causes student eyesight to decline essentially consists in student.It is existing
Child's learning tasks it is heavier, posture is not rectified during reading and writing, and the learning state of long-time high intensity can make child easily
Feel fatigue, eyes become near with books distance and even lain prone on desk in not feeling；In addition, the hair with computer network
Exhibition, more and more children obsesses with online game, but faces computer display screen for a long time, same easy eye strain,
It is involuntary by eyes close to display screen.When child closely reads a book or plays computer, carried if timely can not find to give
Wake up, if things go on like this, the damage to eyes is especially big, thus is necessary to set a kind of when the above-described situation occurs give child to carry
Awake prompting device.
【The content of the invention】
It is an object of the invention to customer service the deficiencies in the prior art, there is provided a kind of simple in construction, easy to use anti-near
Depending on prompting device.
In order to solve the above technical problems, present invention employs following technical proposals：
A kind of myopia prevention prompting device, including the lower pod body that upper pod body and upper pod body are rotatably connected by spring,
It is provided with microprocessor, controller, the distance detector being connected with microprocessor in the upper pod body, one of the controller
Input port connects microprocessor, and an output port of the controller is connected at the micro projector of folder housing forward end.
In the preferred embodiment, the upper pod body is provided with battery capacity indication lamp and switch indication light.
In the preferred embodiment, the upper pod body and lower folder case inside are provided with anti-slip rubber.
Compared with prior art, myopia prevention prompting device of the present invention, can solve the prolonged close eye of child
The problem of easily causing eye damage.The lower pod body being rotatably connected including upper pod body, with upper pod body by spring, institute
State and microprocessor, controller, the distance detector being connected with microprocessor are provided with pod body, one of the controller is defeated
Inbound port connects microprocessor, and an output port of the controller is connected at the micro projector of folder housing forward end.When
When distance detector detects that the eye distance books of child, the distance of display screen do not meet preset value, micro projection
Instrument will be projected out pattern to prompt after being connected to signal in face of child, and child will adjust sitting posture after seeing prompting pattern, from
Move eyes away from books or display screen, avoid damage of the close eye to eye；In addition, myopia prevention prompting device can facilitate
Books or display screen side edge are securely fixed in, it is easy to use, simple to operate.
【Brief description of the drawings】
Fig. 1 is perspective view of an embodiment of the present invention；
Fig. 2 is one of schematic diagram of one embodiment of the invention；
Fig. 3 is the two of the schematic diagram of one embodiment of the invention.
【Specific embodiment】
Clearly complete explanation is made to one embodiment of the invention in conjunction with accompanying drawing：
As shown in figure 1, a kind of myopia prevention prompting device, including it is upper pod body 10, rotatable by spring with upper pod body 10
The lower pod body 20 of connection, the upper pod body 10 is interior to be provided with microprocessor, controller, the distance measurement being connected with microprocessor
Device 30, the input port connection microprocessor of the controller, an output port of the controller are connected at folder
The micro projector 40 of housing forward end.
The upper pod body 10 is provided with battery capacity indication lamp and switch indication light.
Upper pod body 10 and the inner side of lower pod body 20 are provided with anti-slip rubber, can increase friction, so that the myopia prevention carries
Show that device is firmly fixed on books or display screen.
As shown in Figure 2 and Figure 3, in use, myopia prevention prompting device of the present invention is fixed on into books or display screen side
On, the forward lean or when lying prone on the table when child learns or plays computer, distance detector 30 detects eye distance books
Or the horizontal range of display screen is less than preset value, the microprocessor being connected with distance detector 30 sends corresponding signal, control
Device is just reacted, and micro projector 40 is projected pattern, such as a red warning word " Keep a
distance！" or dejected expression pattern etc., in this case, child is reminded after seeing word or pattern, is known
The sitting posture in road oneself is not rectified, and will adjust sitting posture, and automatically by eyes away from books or display screen, it can remind child in time
Keep and learn to play the coverage of computer, so as to avoid damage of the close eye to eye；When child adjusts sitting posture,
Distance detector 30 detects eye distance books or the distance of display screen is not less than preset value, is connected with distance detector 30
Microprocessor will no longer send signal, controller does not receive signal, micro projector 40 is no longer projected pattern,
In this case, do not see that the child of prompting pattern knows that the sitting posture of oneself is proper, it is possible to which that feels at ease continues to learn
Or play and play.So, ensure that in time remind child recover automatically and keep proper sitting posture, with reach pre- myopia prevention and
The effect for avoiding eye from damaging.In addition, myopia prevention prompting device can conveniently be securely fixed in books or display screen side edge, use
It is convenient, simple to operate.
For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise,
Some simple deduction or replace can also be made, are regarded as belonging to protection scope of the present invention.
