Abstract

The invention relates to an anti-myopia writing pen. The anti-myopia writing pen comprises a penholder, a pen gripping sleeve, a pen point and a pen refill; an upper axle seat, a circuit board with an infrared sensor, a lower axle seat, an actuating coil and a thrust rod are successively distributed at the upper part of the penholder from the top down; the anti-myopia writing pen is characterized in that a battery compartment is arranged between the lower axle seat and the actuating coil, and two poles of a battery mounted in the battery compartment are electrically connected with the lower axle seat and the lower axle seat correspondingly. The battery compartment is moved downwards, so that the anti-myopia writing pen has the beneficial effects that 1, the gravity center of the penholder is moved downwards, so that the pen is gripped more stably; 2, the infrared sensor is moved upwards, thereby being more closer to a face and reducing induction blind areas so as to make a reaction more sensitive; 3, operations of assembly and battery replacement in later periods are facilitated, namely the upper axle seat is only required to be assembled at the bottom of a transparent sleeve of the penholder, when the battery is replaced, a cover is only required to be opened or a section of a penholder core is required to be pulled out, and then the anti-myopia writing pen can be operated.

Description

One kind writes Nearsightedness-preventing pen

Technical field：

The invention belongs to Writing instrument field, write Nearsightedness-preventing pen particularly to one kind, in particular by low level battery compartment The Nearsightedness-preventing pen of design.

Background technology：

With microelectronic development, also there is significant progress in electronics Nearsightedness-preventing pen last decade, its penholder top from And under be sequentially distributed battery, upper axle bed, the circuit board with infrared sensor, actuation coil, lower axle bed and throw-out lever；Student makes With this writing process, when face gets too close to desktop, at this moment built-in infrared induction circuit just can receive anti-by face It is emitted back towards the signal coming, deals with through circuit judges, control coil is energized or power-off, coil electricity produces magnetic field suction thrust Magnet on bar makes throw-out lever up tilt, and at this moment pen core is just retracted in the case of not having rear support power upwards, and this pen is just no Method is write, and forms myopic-preventing protection；When desktop leaves to certain distance in face, then throw-out lever resets, and support is arranged at pen core top Just can normally write after power, reach pre- myopic-preventing effect.

At present, the battery of such Nearsightedness-preventing pen is installed in pen arm end, changes battery for convenience, sets in pen arm end It is equipped with a cap for brush.Due to high density button weight weight, somewhat top-heavy sense when holding a pen, the especially little strong point of student's palm is inclined Low, this feel to become apparent from.How to improve the deficiency of existing Nearsightedness-preventing pen, become the object of present invention research.

Content of the invention：

The purpose of the present invention is to design a kind of battery compartment and be arranged on to write Nearsightedness-preventing pen between lower axle bed and coil.

The technical scheme is that be achieved in that：One kind writes Nearsightedness-preventing pen, include penholder, pen cap, nib and Pen core；Penholder top be sequentially distributed from top to bottom axle bed, the circuit board with infrared sensor, lower axle bed, actuation coil and Throw-out lever；It is characterized in that：It is provided with battery compartment between lower axle bed and actuation coil, be arranged on the battery the two poles of the earth pair in battery compartment Should electrically connect with lower axle bed and upper axle bed.

Described lower axle bed and actuation coil are arranged on a core print seat plastic, this core print seat plastic lower axle bed and actuation coil it Between arrange battery compartment, this battery compartment is the longitudinal grooved through penholder axis, fluting an elongated slot middle side part be provided with negative Pole lead, two ends are provided with negative pole stage portion, and a short groove side of fluting is provided with positive wire.

Described penholder comprises Pen-holder sleeve and penholder core, and penholder core is made up of transparent sheath and core print seat plastic, and core print seat plastic plugs In transparent sheath bottom；Upper axle bed and the circuit board with infrared sensor are arranged in this transparent sheath, and penholder core is by transparent sheath Lower end is plugged in described Pen-holder sleeve upper end, and the infrared sensor on holding circuit plate exposes outside.

The battery bin location of the corresponding core print seat plastic of described Pen-holder sleeve offers gathering hole, and this gathering hole is configured with a lid.

It is provided with a decorative ferrule, this decorative ferrule activity is embedded saturating between the transparent sheath of described Pen-holder sleeve and penholder core Bright put, displacement downwards can block the joint portion of transparent sheath and Pen-holder sleeve, and keeps off toward outside the battery compartment of core print seat plastic.

Battery compartment is moved down by the present invention, has the advantages that：1st, penholder decentralization, it is more sane to hold a pen；2nd, infrared Move on sensor, closer to face, reduce sense blind area, reaction is more sensitive；3rd, it is convenient to assembling and the later stage changes battery behaviour Make, the transparent sheath bottom of penholder only needs fit on axle bed, and when changing battery, only need to open lid or penholder core is drawn Go out one section, you can operation.
