Be provided with the T-shaped movable magnet 11 in a section between circle 9, the rear end of movable magnet 11 have one along support ring 12 in axial sliding
Guiding projection 110, the front end of movable magnet has one can be along the inner ring of magnet coil 9 sliding sleeve 111, slip cap in axial sliding
The centre of pipe 111 is provided with the inner chamber 112 with the upper not-go-end tight clamping fit of core storage tube 71, and an iron core spring 10 is nested with sliding sleeve
111 outer end, two ends abut with guiding projection 110 and magnet coil 9 respectively；The inner upper end of penholder 4, on movable magnet 11
Controlling organization 13 is installed in square cavity, an acceleration transducer and a LED are also included in controlling organization 13；Pressure sensor
3rd, lower position switch 5, upper limit position switch 6, magnet coil 9, acceleration transducer and LED electrically connect with controlling organization 13 respectively
Connect.
Preferably, in the application in order that with comfortable, retaining core pipe 2 is the moderate rubber of hardness.
Preferably, when the internal diameter of retaining core pipe 2 is slightly less than 1 external diameter of lead for retractable pencil, the movement of lead for retractable pencil 1 can drive retaining core pipe 2 simultaneously
It is mobile, detect that lead for retractable pencil goes out wick-like state with this.
Preferably, to avoid, the axial movement in penholder 4 of magnet coil 9 is frequent with support ring 12 to collide, it is necessary to fixed bullet
The spring strength of spring 8 is greater than the spring strength of iron core spring 10, is resisted against what magnet coil 9 was fastened in support ring 12.
Preferably, in order to preferably it is convenient and practical, the upper end of penholder 4 is provided with external screw thread, and the cap for brush 14 is provided with internal thread, pen
The upper end of bar 4 and the cap for brush 14 are connected through a screw thread, and the sidepiece of the cap for brush 14 is provided with the pen clip 141 of a fixation, and the upper end of the cap for brush 14 is also
It is provided with a replaceable rubber 15 for wiping.
Preferably, a LED being electrically connected with controlling organization 13, the corresponding LED of penholder 4 are also included in controlling organization 13
Place is arranged to the transparent window beneficial to translumination observation, and when firmly excessive, LED flicker alarm reminds user to note holding a pen
Dynamics.
Preferably, it is preferably to add the stressing conditions for surveying retaining core pipe 2, the outside of penholder 4, the place of holding a pen is provided with 3 along center line
Uniform groove 41, three grooves 41 and the radially staggered distribution of pressure sensor 3, thus have a pressure sensor 3 just to locate
In the positive direction being pressurized, accuracy in detection highest.
When intelligent pencil does not have lead for retractable pencil 1, user normally holds a pen and presses down on propelling pencil, makes the lower end of pen core 7
The slid inward of retaining core pipe 2, the projection 22 on retaining core pipe 2 is touched after slip with the contact of upper limit position switch 6, and controlling organization 13 is obtained
Signal, direct impulse operating current is connected by circuit to magnet coil 9, and movable magnet 11 is moved downward by magnetic attraction,
The compression iron core of movable magnet 11 spring 10 simultaneously presses the core storage tube 71 being nested with it and the pen core 7 being connected on core storage tube 71,
The lead for retractable pencil 1 in core storage tube 71 is set to move out once, subsequent movable magnet 11 is replied by the stretching, extension elastic force of iron core spring 10
To initial position, a work period is completed.The always on direct impulse work before other signals are not received of controlling organization 13
Make electric current.
Further, when lead for retractable pencil 1 touches retaining core pipe 2, because retaining core pipe 2 and lead for retractable pencil 1 are interference fit, lead for retractable pencil 1 is pushed up
Dynamic retaining core pipe 2 slides in and out, when the projection 22 on retaining core pipe 2 is touched after slip with the contact of lower position switch 5, controlling organization
13 are stopped, and now lead for retractable pencil 1 is not extended out also, now continue to press down on propelling pencil, the task again of controlling organization 13, until
Lead for retractable pencil 1 stretches out from retaining core pipe 2.
Further, in normal writing, as the abrasion of lead for retractable pencil 1 is shortened, retaining core pipe 2 also in company with slid inward, works as shield
When the upper protruding block 22 of core pipe 2 touches upper limit position switch 6 again, secondary control goes out lead to controlling organization 13 again, until lead for retractable pencil 1 stretches out.
Further, due to being provided with pressure sensor 3, user's pressure when writing simultaneously in the lower end inside of penholder 4
Maintain in certain normal range (NR), the LED in controlling organization 13 does not work, as user because the reason such as incorrect that holds a pen makes shield
The stress of core pipe 2 is excessive, and press pressure exceedes normal range (NR), and controlling organization 13 sends light by the LED on control panel
Signal, notifies that user writes pressure excessive, allows user to note writing physical strength at any time.
Further, acceleration transducer is also equipped with controlling organization 13, when propelling pencil freely falling body or throwing
When, controlling organization 13 according to sensor signal control the turn-on reversal electric current of magnet coil 9, movable magnet 11 by magnetic field repulses power to
After slide, through core storage tube 71 drive pen core 7, pen core 7 drive lead for retractable pencil 1, lead for retractable pencil 1 drive retaining core pipe 2 to reclaim contract, protect lead for retractable pencil 1
It is without damage, while preventing nib from hurting sb.'s feelings.Upper limit position switch 6 and lower position switch 5 can be used according to the outward appearance of product simultaneously
Different limit switch device is realized.
To sum up, only presently preferred embodiments of the present invention, not for limiting the scope of the present invention, is said by above-mentioned
Bright content, relevant staff completely can without departing from the scope of the technological thought of the present invention', carry out various change with
And modification.The technical scope of this invention is not limited to the content on specification, the shape of all claimed ranges under this invention
Shape, construction, feature and spiritual so-called impartial change with modification, all should include with scope of the presently claimed invention in.
