Background technology:

At present, the learning burden of students in middle and primary schools is generally overweight, student's writing time is more, the reason of its middle school student when writing often due to posture or seat apparatus, easily cause the using state of lettering pen incorrect, particularly pupil, and the student of rural area does not satisfy the requirements due to Family study environment, light and seat are difficult to guarantee and reach normal use, so when more easily causing study and write operation, the state holding lettering pen is not right, this has a significant impact myopia and health, the eyesight influence of posture to writer holding lettering pen is larger, particularly under the darker state of light, the posture holding lettering pen more easily affects the healthy of adolescent student.In order to solve this situation, existing much release for students in middle and primary schools' myopia prevention Nearsightedness-preventing pen, Support for preventing myopia, desk for preventing myopia and anti-myopia bookshelf etc., but these myopia prevention devices existing, structure is single, the scope of application is little, often only have a kind of structure and use pen supporting, use dumb, and alarm function is single, optics, acoustics and vibration function combination accessory can not be used, so, the multiple warning function of a kind of new structure of developmental research and the very promising and economic worth of lettering pen myopia prevention device.

Summary of the invention:

The object of invention of the present utility model is the shortcoming overcoming prior art existence, seek the myopia prevention device designing a kind of and matching used multi-functional prompting state of multiple lettering pen, to be applicable to when students in middle and primary schools or younger librarian are write the occasions such as prompting adjustment writing posture.

To achieve these goals, agent structure of the present utility model comprises: the fixing pen cap, conduction liquid, insulation booth, becket, control panel, button, battery, compression spring, vibrating motor, loudspeaker, photophore and housing, in the inner chamber of the housing of hollow type cylindrical structure, fixedly be shaped with the fixing pen cap, insulation booth, becket, battery, compression spring, vibrating motor, loudspeaker and photophore successively from bottom to top, the top end face of housing is shaped with photophore, and the luminous energy that the illuminator of photophore is sent out appears outside housing; The side of housing is fixedly shaped with control panel, control panel is shaped with respectively 3 ~ 6 buttons, wherein three buttons in button respectively with vibrating motor, loudspeaker, photophore electric connection, form independent power control loop respectively, one of them button in button forms current supply circuit by conduction liquid, becket and battery, realizes the control of power supply to each electrical appliance; In the bottom inner chamber of housing, plug-in type is shaped with the fixing pen cap, the lateral surface of the fixing pen cap is corresponding with the inner cavity surface plug bush structure of housing, the insertion realizing the fixing pen cap is flexible, the inner-cavity structure of the fixing pen cap is hexagon, circle or square, to be adapted to the structure of pen holder of the different profile of multiple lettering pen; Interpolation type is set in the conduction liquid that insulation booth volume 1/3 ~ 2/3 is housed in the insulation booth in housing, conduction liquid is when housing vertical stand-up, can not contacting metal ring, conduction liquid can contacting metal ring when housing offset from perpendicular tilts more than 30 degree angles, makes battery, becket, conduction liquid and control panel formation power circuit; Fixedly be shaped with vibrating motor and loudspeaker in top inner chamber in housing, the lower end of the photophore in the top side face of housing is shaped with compression spring, compression spring one end and cell communication, the other end and control panel electric connection, forms current supply circuit; The upper end of becket is docked with battery, and lower end butts up against on insulation booth.

Conduction liquid described in the utility model has larger surface tension, first-selected mercury in practicality, and the material of becket comprises copper, aluminium or silver, and its resistivity is little, is easy to contact with conduction liquid form power circuit; Vibrating motor, loudspeaker and photophore vibrate respectively after being powered up, the sound and light, make different percipient experience lettering pen to have departed from and correctly write state, play warning function, the writing posture that holds a pen making writer recover correct, reaches myopia prevention effect.

Compared with prior art, its structural principle is simple, and preparation cost is low for the utility model, and support the use flexibly, environment for use is friendly, entirely can control or single control warning circuit, be applicable to the various writer to light, sound and vibration perception, controls flexibly.
