The myopia-preventive intelligent induction pen has the advantages that the myopia-preventive intelligent induction pen can be assuredly normally operated under the condition of over strong environmental infrared rays, simplifies process flows, realizes shorter production time, is convenient for mass production, saves cost, and resolves the problem that writing is inconvenient due to loosening of a pen head.
Description
Technical field
The utility model relates to the writing implement field, relates in particular to a kind of myopia prevention intelligent-induction pen that utilizes infrared ray to find range.
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 wish the to protect young people demand of eyesight, various Nearsightedness-preventing pens arise at the historic moment.
Early stage Nearsightedness-preventing pen reaches the purpose that auxiliary user keeps correct body position with certain profile or frame for movement often.Chinese patent 90223702.0 discloses a kind of being provided with at the place of holding a pen and has met the depression of pointing shape, makes the writer keep the Nearsightedness-preventing pen of correct pen holding posture; This depression Nearsightedness-preventing pen can only make the writer go to hold a pen with correct pen holding posture, can not force the writer to keep correct sitting posture, so myopic-preventing effect is limited.Chinese patent ZL95214039.X discloses a kind of Nearsightedness-preventing pen that is added with pull bar at the penholder rear portion, and the scale of size is arranged on the pull bar, pulls out pull bar when writing, and prevents that to prop up health writer's head and paper are too close; This pull bar Nearsightedness-preventing pen is neither elegant in appearance, and is longer because of pull bar, writes also extremely inconvenient.
Can only play the defective that auxiliary writer keeps sitting posture at above-mentioned Nearsightedness-preventing pen, Chinese patent ZL99230493.8 discloses the scalable Nearsightedness-preventing pen of a kind of pen core.This refill expansion Nearsightedness-preventing pen mainly comprises the infrared induction head that is used for infrared distance measurement, and slidably the pen core cover of tail end band projection is used to control the adapter sleeve that pen core overlaps indentation, and the thrust pin of magnetosphere and carry magnet is arranged in this adapter sleeve.When correct body position was write, health was far away from the nib distance, and the magnetosphere in the adapter sleeve is not worked, and the thrust pin is sagging naturally under the effect of gravity, props up the bossing of pen core cover, makes pen core head be exposed at the pen cap and normally writes outward; When health is crossed when near from nib, thereby the infrared induction head detects the work of hypotelorism control magnetosphere, magnetosphere produces the magnet on the magnetic attraction thrust pin, make the thrust pin depart from the normal position, can not prop up the projection of pen core cover again, thereby make when writing in the pen core head withdrawal pen cap, can't normally write again, play the effect of forcing the writer to keep correct sitting posture.Because the projection of the pen core of this refill expansion Nearsightedness-preventing pen cover tail end realizes that with the copper pin manufacturing process is difficulty relatively, causes projection and thrust pin gap bigger, when therefore normally writing, nib is loosening, writes inconvenience.Fix because of infrared induction head direction simultaneously, when the writer holds a pen direction when rotating because of carelessness, the infrared induction head can't normally be found range, and causes not having myopic-preventing effect.
In order to solve the fixing problem of infrared induction head direction, Chinese patent 200610069022.9 improves on the basis of refill expansion Nearsightedness-preventing pen, discloses the Nearsightedness-preventing pen that a kind of infrared induction head can turn to automatically.This inductive head turns to Nearsightedness-preventing pen respectively to add a metal axonometer at the two ends of the circuit board that the infrared induction head is housed, with the top and the bottom of the corresponding cavity of this metal axonometer a metal shaft needle stand is being installed respectively again, is being finished to circuit board power supply and make circuit board function capable of free rotation by metal axonometer and being connected of metal shaft needle stand; This inductive head turns to Nearsightedness-preventing pen also to install a heavy burden part additional in the circuit board one side opposite with the infrared induction head simultaneously, the heavy burden part drives circuit board and rotates under the effect of gravity, in conjunction with correct pen holding posture, can guarantee that the infrared induction head is all the time towards the human body direction.Though this inductive head turns to pen to solve the fixing problem of infrared induction head direction, the problem that nib is loosening is not because the manufacturing process of copper pin difficulty is so still be well solved.To turn to the metal axonometer of pen be that a section is half elliptic little rectangular with the part that circuit board welds mutually to this inductive head simultaneously, and contact area is less relatively, welding difficulty, production duration.
Above-mentioned two kinds of Nearsightedness-preventing pens that use infrared distance measurement to control, problem of common existence, be exactly that infrared ray when external environment is strong excessively, such as under strong sunshine or when strong pyrotoxin indoor arranged, the infrared ray of external environment will be received by the infrared induction head.Because infrared induction head received power is limited, the environment infrared ray can squeeze out infrared induction head range-measurement infrared originally, thereby causes the infrared distance measurement disabler, and Nearsightedness-preventing pen can't operate as normal.
The utility model content
Loosening in order to solve infrared induction Nearsightedness-preventing pen nib, produce and use duration, the external environment infrared ray cross when strong can't operate as normal etc. problem, the utility model improves the Chinese patent ZL99230493.8 and 200610069022.9 that becomes known technology, a kind of myopia prevention intelligent-induction pen is provided, comprise battery compartment, battery, go up the axonometer seat, go up axonometer, light-transmission tube, circuit board, infrared induction head, down axonometer, lower shaft needle stand, coiled wire-wound coil, magnet, thrust pin, push pin, tickler spring, pen core cover, pen core, written pipe, control valve, heavy burden part; The whole shaft of a writing brush is joined successively by battery compartment, light-transmission tube, control valve and nib pipe and forms; Wherein anode joins by the conductive metal sheet of spring in the battery compartment and battery compartment inside, and GND connects the conductive seat of battery compartment; Last axonometer seat is installed on the conductive seat of battery compartment, and the lower shaft needle stand is installed in worker's shape skeleton top on control valve top, and last axonometer is installed on the end of circuit board by battery compartment, and following axonometer is installed on the end of circuit board by control valve; The infrared induction head is installed on the circuit board one side, and the heavy burden part is installed on the circuit board another side opposite with the infrared induction head; Described coiled wire-wound coil one rear line head is on the lower shaft needle stand, and other end the end of a thread is by the conductive metal sheet of the connection of the wire casing on light-transmission tube battery compartment inside, and the coiled wire-wound coil main body is wound on worker's shape skeleton depressed part on control valve top; Thrust pin top is equipped with magnet, and the thrust pin is installed in the cavity of control valve by the bearing at middle part; Pen core is contained in pen core cover inner chamber, and pen core cover top is equipped with pushes pin, and pushes pin to pass tickler spring and be against thrust pin bottom; It is characterized in that:
