Abstract

The utility model discloses a sight health care pen capable of reliably working. A pen holding sleeve and a set of sight protecting device are added on a penholder part of an ordinary pen, wherein the cross section of a penholder is an ellipse; the surface of the pen holding sleeve is provided with a positioning pit. When a distance between human eyes and writing paper surface is smaller than a specified distance, the sight protecting device can remind a writer of correcting sitting positions. The pen holding sleeve of the utility model causes the writer to hold the pen at a specific direction in order to ensure that the utility model works effectively and reliably.

Description

The vision health protection pen of energy reliably working

The utility model relates to a kind of writing implement, particularly a kind of vision health protection pen.

According to human eye health care requirement, people are when writing or read, human eye must be apart from the certain distance of paper, otherwise will have a strong impact on eyesight, the existing writing implement that generally uses, not outer in pen, ball pen or pencil, these writing implements can not impel writer, especially teen-age eyes to keep normalized distance from writing, and cause myopia or other vision disorders easily.

The purpose of this utility model is at above-mentioned situation, in conjunction with my the previous patent application that proposes, overcomes the deficiencies in the prior art, provides a kind of and can remind Writer's eyes to keep normal Writing distance, and the effective vision health protection pen of reliably working.

The vision health protection pen of the utility model energy reliably working is made up of pen core, nib, penholder and the pen cap, and pen core is arranged in penholder and nib is connected the inner cavity that forms in back, and the pen cap covers the part of the whole and penholder of nib; One section that penholder is adjacent with nib is a pen cap, and its outer surface has a location pit at least; Device is a cover vision protection device in the penholder.

Vision protection device in the penholder is made up of power supply, gauge tap, monitoring feedback device, control circuit, warning device and wiring board; Wherein, the monitoring feedback device is contained in the termination portion of penholder away from a written end, is connected with control circuit, and warning device is connected on the output of control circuit.

The penholder face shaping is along its length streamlined, and cross section is oval.

Vision protection device in the utility model penholder can remind the writer to keep normal Writing distance, vision protection, prevents hunchback; Cross section is the special orientation that has been combined to form of oval-shaped penholder shape and pen cap location pit; can guide the writer correctly to hold a pen; make it both feel comfortable, make the monitoring feedback device all the time towards Writer's head again, the assurance vision protection device is reliably worked effectively.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the longitudinal sectional view of the vision health protection pen of the utility model energy reliably working;

Fig. 2 is the I-I cutaway view of Fig. 1.

Referring to Fig. 1:

The vision health protection pen of the utility model energy reliably working, form by pen core 1, nib 2, penholder 31 and the pen cap (not drawing among the figure), pen core 1 is arranged in nib 2 is connected the inner formation in back with penholder 31 cavity, and the pen cap covers the part of written 2 whole and penholder 31; On the penholder 31 with nib 2 adjacent one section be a pen cap 4, three different positions of its outer surface have the pit 41 of parabolic shape, referring to Fig. 2; Penholder 31 face shapings are along its length streamlined, and cross section is oval.

One cover vision protection device 32 also is housed in the penholder 31, and it is made up of power supply 321, gauge tap 322, monitoring feedback device 323, control circuit 324, warning device 325 and their connection line plate; Wherein, monitoring feedback device 323 is contained in the termination portion of penholder 31 away from nib 2 one ends, is beneficial to the emission and the reception of signal.Monitoring feedback device 323 is connected with control circuit 324, and warning device 325 is connected on the output of control circuit 324.

Cross section be the shape of oval-shaped penholder 31 and pen cap 4 the location pit be combined to form a special orientation; the writer correctly holds a pen with guiding; guarantee that monitoring feedback device 323 all the time towards Writer's head, guarantees that the vision protection device 32 in the penholder 31 is reliably worked effectively.

The monitoring feedback device 323 of the vision health protection pen of this energy reliably working is made up of infrared emission tube and infrared receiver tube.

Warning device 325 can be luminous tube, and this apparatus structure is simple, does not disturb to external world; Can be acoustical generator, this device provides a kind of extraneous supervision for the writer; Can have eccentric micromachine for one, this device does not have the stimulation of sound, light, and because the shake of pen makes the writer have to correct sitting posture owing to can not normally writing.

The gauge tap 322 of the vision health protection pen of this energy reliably working can be a mechanical contact switches, adjacent with pen cap 4, when being put, the pen cap can contact with it, when the writer wants to use lettering pen to write and unplugs the pen cap, its switch key moves immediately, entire circuit is connected, and is in running order; After with complete this pen the pen cap being recovered penholder as the writer, switch key is i.e. action again, cuts off the electricity supply automatically, and entire circuit is in off working state.

The gauge tap 322 of the vision health protection pen of this energy reliably working can also be the soft-touch control of an induction type, adjacent with pen cap, when the writer holds a pen when writing, hand touches soft-touch control, entire circuit is connected, in running order, so just make this health care pen can effectively utilize electric energy, this technology can be referring to previous ripe circuit.

When the writer write with pen, gauge tap 322 was in opening, and power supply 321 is connected, vision protection device 32 work.When Writer's eyes and when writing distance between the paper less than predetermined distance, the signal folding that monitoring feedback device 323 sends reflects through human body head again and is received, after control circuit 324 processing, drive warning device 325 and remind writers to note correcting sitting postures.
