Abstract
The invention discloses an anti-myopia prompter which can solve the problem that eyes of children are easily damaged when the children use the eyes for a short time. The projector comprises an upper clamp shell and a lower clamp shell which is rotatably connected with the upper clamp shell through a spring, wherein 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, and one output port of the controller is connected with the miniature projector arranged at the front end of the upper clamp shell. When the distance detection device detects that the distance between the eyes of the child and the book and the distance between the eyes of the child and the display screen do not accord with preset values, the micro projector projects a pattern in front of the child to give a prompt after receiving the signal, the child can adjust the sitting posture after seeing the prompt pattern, the eyes are automatically far away from the book or the display screen, and the damage to the eyes caused by using the eyes at a short distance is avoided; in addition, the myopia prevention prompter 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
[technical field]
The present invention relates to electronics field, particularly relate to a kind of myopia prevention prompting device.
[background technology]
The eyes are the windows of the mind, has the hope that two pupils that a pair of becomes clear are a lot of people.But current present situation but, is more and more carried out children and is worn and play spectacles.Add up according to education department's " national myopia preventing and treating job posting ", the rate of myopia of adolescents in China student, children occupies second place of the world, pupil's rate of myopia is 28%, 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 become a puzzlement head of a family's difficult problem, also result in the great attention of government department and various circles of society.
Domestic and international expert's research shows, the reason causing student eyesight to decline mainly is that student is not good by eye custom.Present child's learning tasks are heavier, and during reading and writing, posture is not rectified, and the learning state of long-time high strength can make child very easily feel tired, become closely even lie prone on desk at unconscious middle eyes and books distance; In addition, along with the development of computer network, more and more children obsesses with online game, but for a long time in the face of computer display screen, same easily eye strain, involuntary by eyes near display screen.When child closely reads a book or plays computer, if can not find timely to remind, if things go on like this, large especially to the damage of eyes, be thus necessary to arrange a kind of prompting device when the above-described situation occurs child being given to remind.
[summary of the invention]
The object of the invention is to customer service the deficiencies in the prior art, provide the myopia prevention prompting device that a kind of structure is simple, easy to use.
For solving the problems of the technologies described above, present invention employs following technical proposals:
A kind of myopia prevention prompting device, the lower folder housing comprising folder housing, be rotatably connected by spring with upper folder housing, microprocessor, controller, the distance detector that is connected with microprocessor is provided with in described upper folder housing, an input port of this controller connects microprocessor, and an output port of this controller is connected at the micro projector of folder housing forward end.
In the preferred embodiment, described upper folder housing is provided with battery capacity indication lamp and switch indication light.
In the preferred embodiment, described upper folder housing 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 problem that the long close eye of child easily causes eye to damage.The lower folder housing comprising folder housing, be rotatably connected by spring with upper folder housing, microprocessor, controller, the distance detector that is connected with microprocessor is provided with in described upper folder housing, an input port of this controller connects microprocessor, and an output port of this controller is connected at the micro projector of folder housing forward end.When distance detector the eye distance books of child detected, the distance of display screen do not meet preset value time, pattern will be projected out to point out in face of child after micro projector receives signal, child will adjust sitting posture after seeing prompting pattern, automatically by eyes away from books or display screen, avoid the damage of close eye to eye; In addition, myopia prevention prompting device conveniently can be securely fixed in books or display screen side edge, easy to use, simple to operate.
[accompanying drawing explanation]
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 schematic diagram two of one embodiment of the invention.
[specific embodiment]
Now by reference to the accompanying drawings clear complete explanation is made to one embodiment of the invention:
As shown in Figure 1, a kind of myopia prevention prompting device, the lower folder housing 20 comprising folder housing 10, be rotatably connected by spring with upper folder housing 10, microprocessor, controller, the distance detector 30 that is connected with microprocessor is provided with in described upper folder housing 10, an input port of this controller connects microprocessor, and an output port of this controller is connected at the micro projector 40 of folder housing forward end.
Described upper folder housing 10 is provided with battery capacity indication lamp and switch indication light.
Be provided with anti-slip rubber inside upper folder housing 10 and lower folder housing 20, can friction be increased, be firmly fixed on books or display screen to make described myopia prevention prompting device.
As shown in Figure 2 and Figure 3, during use, myopia prevention prompting device of the present invention is fixed on books or display screen side, forward lean or when lying prone on the table when child's study or when playing computer, distance detector 30 detects that the horizontal range of eye distance books or display screen is less than preset value, and the microprocessor be connected with distance detector 30 sends corresponding signal, and controller is just reacted, micro projector 40 is made to project pattern, such as one red warning word " Keepadistance! " an or dejected expression pattern etc.; in this case; child is reminded after seeing word or pattern; know that the sitting posture of oneself is not rectified; will sitting posture be adjusted; automatically by eyes away from books or display screen, it can be reminded child to keep in time and learn the coverage of object for appreciation computer, thus avoids the damage of close eye to eye; When child adjusts sitting posture, the distance that distance detector 30 detects eye distance books or display screen is not less than preset value, the microprocessor be connected with distance detector 30 no longer will send signal, controller does not receive signal, micro projector 40 is made no longer to project pattern, in this case, do not see that the child of prompting pattern knows that the sitting posture of oneself is proper, the continue studying just can felt at ease or played games.Like this, just ensure that and remind child automatically recover and keep proper sitting posture, with the effect reaching pre-myopia prevention and avoid eye to damage in time.In addition, myopia prevention prompting device conveniently can be securely fixed in books or display screen side edge, easy to use, 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, all should be considered as belonging to protection scope of the present invention.
