Description

The myopia prevention intelligent-induction shrinks pen

Technical field:

The utility model relates to a kind of myopia prevention intelligent-induction and shrinks pen.

Background technology:

Writing posture is incorrect, and eyes and paper hypotelorism are the major reasons that causes adolescent myopia.Thereby traditional pen stationery can not force the writer to keep the correct body position vision protection, if it is Writer's conscious to want to prevent that myopia from can only rely on.Yet relying on the relatively poor relatively teenager of self-control to remove conscious vision protection is the comparison difficulty.Therefore, in order to satisfy the head of a family and society hope the to protect young people demand of eyesight, various Nearsightedness-preventing pens arise at the historic moment.

Utility model patent in 2009 has announced that the utility model name is called active myopia prevention and writes pen, and this characteristic feature of an invention is to detect through infrared induction, accomplishes the pen core retraction through frame for movement, just can achieve the goal through the gravity compression when writing.Its shortcoming one: firmly low weight when writing because the interior spring of having used is applied to pen, even behind the nib retraction, can also write out word, can not arrive the effect of retraction fully.Two, this product needs the inking chamber of supporting special use, must buy the inking chamber of former factory after the user uses up, and the user is original to buy the custom that ink bottle blots and changed, and causes user's use cost to increase.Three, aspect detection of electrons,, exist and be vulnerable to the sunshine on daytime because this product does not adopt infrared narrow ripple filter, with the interference of light, on electric circuit inspection, do not adopt detection of dynamic, also can exist out of control.

Summary of the invention:

In order to solve the problems of the technologies described above, the utility model provides a kind of myopia prevention intelligent-induction to shrink pen.

The utility model solves the technical scheme that its technical problem adopted: a kind of myopia prevention intelligent-induction shrinks pen; Comprise a tail cap, penholder glue spare, written cap, nib, be installed in inking chamber assembly of penholder glue spare the latter half and the shaft of a writing brush fixed cover that is used for fixing; Said nib is fixed on this inking chamber assembly; The top of said inking chamber assembly is provided with magnet, and the top of said magnet is provided with a movable iron block, and said movable iron block is connected with travelling gear B through a movable axis; Be provided with a battery and the PCBA assembly that is positioned at below this battery in said penholder glue spare the first half; Said PCBA assembly below is connected with a drive motor, is equipped with one on the said drive motor and forms gear-driven travelling gear A with travelling gear B, and said PCBA assembly is provided with infrared receiver and RF transmitter.

In order to increase capacitance, improve service efficiency, further: said battery is a rechargeable battery, and said rechargeable battery is provided with charging socket, and said charging socket is arranged in the tail cap.

Further: said inking chamber assembly comprises ink cabin, piston, shaft of a writing brush suction slip handle and as fixture and form the shaft of a writing brush keeper of cover, said magnet is the loam cake of this shaft of a writing brush keeper.

In order to prevent the movable axis move left and right, further: be with a locating ring on the said movable axis, said locating ring is fixed in the penholder glue spare.

The utility model adopts the electro-motor transmission, and the engage mechanical parts can retract to nib in the shaft of a writing brush completely; Adopt Electronic Control simultaneously; Realize detection of dynamic, strengthen reliability, and be on the structure through in the suction of common pen, improving; It is not change on the original operating habit that blots, thereby this device can be used repeatedly.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Among the figure: 1, a tail cap; 2, charging socket; 3, rechargeable battery; 4, PCBA assembly; 5, drive motor; 6, travelling gear A; 7, travelling gear B; 8, movable axis; 9, movable iron block; 10, magnet; 11, shaft of a writing brush keeper; 12, shaft of a writing brush suction slip handle; 13, piston; 14, ink cabin; 15, shaft of a writing brush positioning sleeve; 16, written cap; 17, penholder glue spare; 18, RF transmitter; 19, infrared receiver; 20, nib; 21, locating ring.

The specific embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

A kind of myopia prevention intelligent-induction shown in accompanying drawing 1 shrinks pen; Comprise a tail cap 1, penholder glue spare 17, written cap 16, nib 20, be installed in inking chamber assembly of penholder glue spare 17 the latter halfs and the shaft of a writing brush fixed cover 15 that is used for fixing; Said written 20 are fixed on this inking chamber assembly; Said inking chamber assembly comprises ink cabin 14, piston 13, shaft of a writing brush suction slip handle 12 and as fixture and form the shaft of a writing brush keeper 11 of cover, said shaft of a writing brush keeper 11 tops use a magnet 10 to be its loam cake.The top of said magnet 10 is provided with a movable iron block 9; Said movable iron block 9 is connected with travelling gear B 7 through a movable axis 8; In order to prevent movable axis 8 move left and right, on said movable axis 8, be with a locating ring 21, said locating ring 21 is fixed in the penholder glue spare 17.Be provided with a battery 3 and the PCBA assembly 4 that is positioned at below this battery 3 in said penholder glue spare 17 the first half; Said PCBA assembly 4 belows are connected with a drive motor 5; Be equipped with one on the said drive motor 5 and form gear-driven travelling gear A 6 with travelling gear B 7, said PCBA assembly 4 is provided with infrared receiver 18 and RF transmitter 19.In order to increase capacitance, improve service efficiency, said battery 3 is a rechargeable battery, and said rechargeable battery is provided with charging socket 2, and said charging socket 2 is arranged in the tail cap 1.

Requirement general when Primary-School Pupils in Learning is write is: grasp " chi one fist one-inch " principle when writing.(that is: qn eye distance books one chi, along a fist, the position of writing is apart from the nib one-inch apart from table for chest.) pupil when the process of study just, often generally can both note at the beginning, but after the time grown, unavoidable can head more and more down; Health is also more and more near desk, and this causes the main cause of myopia, hunchback etc. in the future often, through this device, when the pupil when writing; At first PCBA assembly 4 constantly sends signals through RF transmitters 19, runs into object (student's health) time in the place ahead when signal and returns, and receives signals through infrared receiver 18 then, thereby analyzes the signal that is received through this PCBA assembly 4 again; Judge whether this student Writing distance at this moment is correct, if incorrect words, PCBA assembly 4 starts drive motors 5, thereby transmission arbor wheel A 6 is clockwise rotated; Because travelling gear B 7 and travelling gear A 6 engagements, then this moment, travelling gear B 7 also rotates, and moves thereby drive on the inking chamber assembly in penholder glue spare 17 the latter halfs; And because nib 20 is fixed on this inking chamber assembly, nib retracts in the penholder glue spare 17, can't write again; Thereby remind student's writing posture, when the student sat back correct body position again, PCBA assembly 4 restarted drive motor 5; Transmission arbor wheel A 6 is rotated counterclockwise, and then this moment, nib 20 moves down; Get back to the home position, can make the pupil in constantly correcting through this device, gradually form correct writing style.

Simultaneously; Because this device is through in the suction of common pen, improving, so this inking chamber assembly is identical with common pen, can using repeatedly; When this device does not have ink; Can with shaft of a writing brush fixed cover 15 this device be taken apart through the penholder glue spare 17 outwarded winding, and owing to be that attraction through magnetic is in contact with one another between movable iron block 9 and the magnet 10, so be very easily it to be separated taking apart.
