Abstract
The utility model relates to an anti-myopia alarm, and comprises a casing suitable for being hung on ears, a power arranged in the casing, and an alarm device containing an integrated circuit chip, a mercury balancing switch, and an eccentric vibration direct current motor. The appearance of the utility model is pretty and beautiful, the carrying and the operation are convenient, through adopting the mode of the vibration alarm, the influence to the others can be effectively avoided; in addition, the utility model also overcomes the limitation of the single alarm of the prior product, and through arranging two different alarm modes, the requirement of students to use in different occasions can be met.
Description
Technical field
The utility model relates to a kind of myopia prevention alarm, especially relates to the myopia prevention alarm that a kind of user of prompting keeps distance between eyes and the books.
Background technology
Have much in order to the device that prevents the myoporthosis sitting posture of student at present, its structure also has nothing in common with each other.As notification number is the disclosed a kind of student eyesight posture protector of CN2112984; and notification number is the disclosed a kind of Strap for preventing nearsight of CN2291835, all be in order to rectifying sitting posture of student, but the common weak point of above-mentioned stream oriented device is a complex structure; the cost of manufacture height uses inconvenient.And existing commercially available a kind of antimyopia ear-hanger, the said goods complex structure, awkward defective have then been overcome preferably, be buckled on the ear after needing only the power-on switch when it uses, when student's head turns forward above certain angle when making the too close books of eyes (head too low and), hummer in the ear-hang promptly sends chimes of doom, remind the student to raise one's head, but the weak point of such ear-hang is owing to report to the police by buzzing, the student uses at school the time, classmate around the chimes of doom that sends can influence and teacher's teaching.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of result of use good at above-mentioned prior art present situation, can not produce the myopia prevention alarm of interference to other people.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this myopia prevention alarm, comprise and one suitable hang over shell on the ear, power supply in the enclosure be installed and included integrated circuit chip and the warning device of mercury balance cock, and power switch, it is characterized in that described warning device also includes an eccentric vibration direct current generator, this off-centre vibration direct current generator is electrically connected with integrated circuit chip, power switch, mercury balance cock and power supply.
As further improvement, described warning device also can include a piezo, be electrically connected with integrated circuit chip, power switch, mercury balance cock and power supply after this piezo and the parallel connection of eccentric vibration direct current generator, wherein said power switch is a two-way switch, is available for users to select different type of alarms with this.
Compared with prior art, advantage of the present utility model is: the utility model not only profile small and exquisite attractive in appearance, portably use conveniently, and, can effectively avoid influence to other people by adopting the mode of vibration alarming; The utility model has also overcome the limitation of the existing single warning of this series products in addition, by two kinds of different type of alarms are set, can satisfy the needs that the different occasions of student are used.
Description of drawings
Fig. 1 is the structural representation (removing lid) of the utility model embodiment.
Fig. 2 is the profile synoptic diagram of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, body case of annunciator of the present utility model is made the suitable shape that hangs on student's ear, and it is to be formed by screw attachment by a box body 6 and a lid 7.The power supply of alarm and warning device are installed in the box body, report to the police and adopt vibration and buzzing dual mode.
Warning device is made up of off-centre vibration direct current generator 1, piezo 2, integrated circuit chip 3, power switch 8 and mercury balance cock etc. 4, connect integrated circuit chip 3, power switch 8 and mercury balance cock 4 after eccentric vibration direct current generator 1 and piezo 2 are in parallel, join with power supply 5 then, power supply 5 adopts button cell, and power switch is a two-way switch.
During use, can select type of alarm by two-way switch, alarm is hung on the ear, when being lower than the angular range that sets forward right overhead, the mercury in the mercury balance cock 4 just flows forward, with power connection, eccentric vibration direct current generator 1 produces vibration, or piezo 2 sends chimes of doom, reminds the student to raise one's head, and sits collection.After the student sat collection, the mercury in the mercury balance cock 4 will return to fully recover from an illness originally and put, and power supply is disconnected, and eccentric vibration direct current generator 1 or piezo 2 just stop vibration automatically or stop to send chimes of doom.
The mode that alarm of the present utility model also can adopt single vibration to report to the police, warning device in the alarm need not piezo, it vibrates direct current generator, integrated circuit chip, power switch and mercury balance cock etc. by off-centre and forms, be coupled to each other by power lead, power switch adopts common toggle switch.
