Abstract
The utility model discloses a kind of writing on the blackboard instrument, described writing on the blackboard instrument is made up of magnetic pen and magnetic sheet, described magnetic pen comprises penholder and the magnetic writerhead that is embedded on described penholder and demagnetic stack, described magnetic sheet comprises plate face, glass plate and scrubbing brush, described glass plate is laid on described plate face, described scrubbing brush is arranged on the bottom of described magnetic sheet, described scrubbing brush is provided with arc groove and bar shaped brush.The superior effect of the utility model writing on the blackboard instrument is: writing on the blackboard instrument is acted on by magnetic pen and cooperatively interacting of magnetic sheet, and the magnetic-particle be contained in plate face can adsorb on a glass by the magnetic writerhead of magnetic pen, thus forms writing.And bar shaped brush can eliminate the magnetic force adsorbing magnetic-particle on a glass, thus the writing on glass plate can be erased, achieve the Palingraphia of writing on the blackboard instrument.Writing on the blackboard tool construction is simple, easy to use, is suitable for the place such as classroom, family and uses.
Description
Technical field
The utility model relates to educational aid field, is specifically related to a kind of writing on the blackboard instrument.
Background technology
Blackboard and chalk are the common tools for imparting knowledge to students.At present, blackboard is divided into blackboard according to color difference, blank and green plate.Traditional blank (blackboard) generally all needs scrubbing brush wiping, but also needs ink (powder) pen supporting with it, just can make the best use of everything.Although reach the object of teaching, the waste of resource is very serious.The most function ratio of writing on the blackboard instrument of peddling in the market is more single, and can not clean blackboard eraser, otherwise is exactly that cleaning fluid is easy to be made dirty, so just only has replacing cleaning fluid, thus causes waste, improve cost, use very inconvenient.
In most of teaching process, still adopt blackboard and chalk as main writing on the blackboard instrument at present, but this drawback wherein and harm apparent, chalk can not recycle, and needs constantly to spend to buy, and is a no small spending.And the chalk dust that chalk produces in writing process is easily inhaled into respiratory tract, enters lung, injury is greatly produced to human body.In addition, owing to also will erase the board, not only chalk dust disorderly flies, and adds work burden.
Utility model content
The utility model provides a kind of writing on the blackboard instrument, and to solve in the process of existing chalk and blackboard writing on the blackboard, chalk dust is more and use inconvenient technical problem.
In order to solve above technical problem, the technical scheme that the utility model is taked is:
A kind of writing on the blackboard instrument, described writing on the blackboard instrument is made up of magnetic pen and magnetic sheet, described magnetic pen comprises penholder and the magnetic writerhead that is embedded on described penholder and demagnetic stack, described magnetic sheet comprises plate face, glass plate and scrubbing brush, described glass plate is laid on described plate face, described scrubbing brush is arranged on the bottom of described magnetic sheet, described scrubbing brush is provided with arc groove and bar shaped brush.
Be preferably, inside, described plate face accommodates magnetic-particle.
Be preferably, described bar shaped brushes and is provided with degaussing gear.
After employing technique scheme, the utility model writing on the blackboard instrument is used in conjunction with each other by magnetic pen and magnetic sheet, the magnetic-particle be contained in plate face can adsorb on a glass by the magnetic writerhead of magnetic pen, thus formation writing, and bar shaped brush can eliminate the magnetic force adsorbing magnetic-particle on a glass, thus the writing can erased on glass plate, achieve the Palingraphia of writing on the blackboard instrument.The places such as writing on the blackboard tool construction is simple, easy to use, is suitable for classroom, family use.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the first partial view of the utility model writing on the blackboard instrument;
Fig. 2 is the second partial view of the utility model writing on the blackboard instrument.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 2, writing on the blackboard instrument is made up of magnetic pen 1 and magnetic sheet 2, and wherein magnetic pen 1 comprises penholder 11 and the magnetic writerhead 12 that is embedded on penholder 11 and demagnetic stack 13, and demagnetic stack 13 can eliminate the magnetic force of magnetic writerhead 12.Magnetic sheet 2 comprises plate face 21, glass plate 22 and scrubbing brush 23, and glass plate 22 is laid on plate face 21, and scrubbing brush 23 is arranged on the bottom of magnetic sheet 2, scrubbing brush 23 is provided with arc groove 231 and bar shaped brush 232.Arc groove 231 can hold magnetic pen 1, and the inside in plate face 21 accommodates magnetic-particle, and scrubbing brush 23 can bottom magnetic sheet 2 on guide rail horizontally slip, thus the effect of erasing characters can be played, bar shaped brush 232 is provided with degaussing gear.
In the process of writing, when in the process that the magnetic writerhead 12 of magnetic pen 1 writes on glass plate 22, magnetic writerhead 12 can adsorb the magnetic-particle be contained in plate face 2, thus magnetic-particle is adsorbed on writing glass plate 22 presenting and writes.When needing to wipe the writing on glass plate 22, slip scrubbing brush 23, due to bar shaped brush 232 being provided with degaussing gear, under the active force of degaussing gear, the magnetic-particle be adsorbed on glass plate 22 can come off from glass plate 22, and the writing on glass plate 22 disappears.
The utility model writing on the blackboard instrument is by the interaction of magnetic pen 1 with magnetic sheet 2, and the magnetic-particle be contained in plate face 21 can be adsorbed on glass plate 22 by the magnetic writerhead 12 of magnetic pen 1, thus forms writing.And bar shaped brush 232 can eliminate the magnetic force being adsorbed on magnetic-particle on glass plate 22, thus the writing on glass plate 22 can be erased, achieve the Palingraphia of writing on the blackboard instrument.In time not needing to write, magnetic pen 1 being placed in arc groove 231. the places such as writing on the blackboard tool construction is simple, easy to use, is suitable for classroom, family use.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
