Abstract

The invention provides an anti-myopia prompter, which comprises an upper clamp shell and a lower clamp shell, wherein the lower clamp shell is rotatably connected with the upper clamp shell through a spring, a microprocessor, a controller and a distance detection device connected with the microprocessor are arranged in the upper clamp shell, one input port of the controller is connected with the microprocessor, one output port of the controller is connected with a micro projector arranged at the front end of the upper clamp shell, and an electric quantity indicator lamp and a switch indicator lamp are arranged on the upper clamp shell. The anti-myopia prompter can solve the problem that eyes of children are easy to damage when the children use the eyes for a long time at a short distance, can be conveniently and firmly fixed at the side edge of a book or a display screen, and is convenient to use and simple to operate.

Description

The myopia prevention prompting device that a kind of child is suitable for

【Technical field】

The present invention relates to electronics field, more particularly to the myopia prevention prompting that a kind of child is suitable for 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 increasingly to carry out children to have worn glasses for the myopia.According to education department 《National myopia preventing and treating job posting》Statistics, adolescents in China student, child rate of myopia Second place of the world is occupied, pupil's rate of myopia is 28%, and junior school student's rate of myopia is 60%, and high school student is near Rate is regarded as 85%, university students' rate of myopia is 90%, and large-scale myopia population not only becomes tired The difficult problem of the head of a family is disturbed, the great attention of government department and various circles of society is also result in.It is domestic Outer expert's research shows, causes student eyesight that student is essentially consisted in the reason for decline and be accustomed to not with eye It is good.Present child's learning tasks are heavier, and during reading and writing, posture is not rectified, and long-time is high-strength The learning state of degree can make child easily feel fatigue, and in not feeling, eyes are become with books distance It is near even to lie prone on desk；Additionally, with the development of computer network, more and more children Online game is obsessed with, but faces computer display screen for a long time, same easily eye strain, It is involuntary by eyes near display screen.When child closely reads a book or plays computer, if not Timely can find to give and remind, if things go on like this, the damage to eyes is especially big, thus have must A kind of prompting apparatuss for giving prompting when the above-described situation occurs to child are set.

【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 structure, The myopia prevention prompting device that child easy to use is suitable for.

To solve above-mentioned technical problem, following technical proposals are present invention employs：A kind of child fits Myopia prevention prompting device, including upper pod body and upper pod body be rotatably connected by spring Lower pod body, be provided with microprocessor, controller with microprocessor phase in the upper pod body Distance detector even, an input port connection microprocessor of the controller, the control One output port of device is connected at the micro projector of folder housing forward end, the upper pod Body is provided with battery capacity indication lamp and switch indication light.

Preferably, the upper pod body and lower folder case inside are provided with anti-slip rubber.

Compared with prior art, the myopia prevention prompting device that child of the present invention is suitable for, can solve Certainly the prolonged close eye of child easily causes the problem of eye damage.Including upper pod The lower pod body that body and upper pod body are rotatably connected by spring, sets in the upper pod body There are microprocessor, controller, the distance detector being connected with microprocessor, the controller One input port connects microprocessor, and an output port of the controller is connected at folder The micro projector of housing forward end.When distance detector detects the eye distance book of child This, the distance of display screen is not when meeting preset value, micro projector is connected to after signal will be Pattern is projected out in face of child to point out, child will adjust sitting posture after seeing prompting pattern, Automatically by eyes away from books or display screen, it is to avoid damage of the close eye to eye；This Outward, the myopia prevention prompting device that child is suitable for can conveniently be securely fixed in books or display screen side Place, it is easy to use, simple to operate.

【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, The myopia prevention prompting device that a kind of child is suitable for, including upper pod body 10, and upper pod body 10 it is logical Cross the lower pod body 20 that spring is rotatably connected, be provided with the upper pod body 10 microprocessor, Controller, the distance detector 30 being connected with microprocessor, an input of the controller Mouth connection microprocessor, an output port of the controller are connected at folder housing forward end Micro projector 40, the upper pod body 10 are provided with battery capacity indication lamp and switch indication light.

Anti-slip rubber is provided with the inside of upper pod body 10 and lower pod body 20, friction can be increased, So that the myopia prevention prompting device that the child is suitable for is firmly fixed on books or display screen.

As shown in Figure 2 and Figure 3, during use, the myopia prevention that child of the present invention is suitable for is carried Show that device is fixed on books or display screen side, when child learn or play computer when forward lean or When lying prone on the table, distance detector 30 detect the level of eye distance books or display screen away from From less than preset value, the microprocessor being connected with distance detector 30 sends corresponding signal, controls Device processed is just reacted, and makes micro projector 40 project pattern, such as one red warning Word " Keep a distance！" or a dejected expression pattern etc., in this case, Child is reminded after seeing word or pattern, it is known that the sitting posture of oneself is not rectified, and will be adjusted Sitting posture, automatically by eyes away from books or display screen, it can remind child to keep and learn in time The coverage for playing computer is practised, so as to avoid damage of the close eye to eye；Work as child The distance for adjusting sitting posture, the detection eye distance books of distance detector 30 or display screen is not little In preset value, the microprocessor being connected with distance detector 30 will no longer send signal, control Device does not receive signal, makes micro projector 40 no longer project pattern, in this case, Do not see prompting pattern child know that the sitting posture of oneself is proper, it is possible to feel at ease after Continuous study or object for appreciation are played.So, ensure that Positive sitting posture, with the effect for reaching pre- myopia prevention and avoiding eye damage.Additionally, myopia prevention is carried Show that device can conveniently be securely fixed in books or display screen side edge, it is easy to use, simple to operate.

For general technical staff of the technical field of the invention, without departing from the present invention On the premise of design, some simple deduction or replace can also be made, is regarded as belonging to this Bright protection domain.
