So traditional chalk is write both unhygienic, be unfavorable for teaching again, and give Faculty and Students healthyly bring injury.
The utility model content
The utility model has overcome the deficiency of prior art, and a kind of no dust pollution again easy to use is provided, and avoids the healthy magnetic writing board that is endangered and improved academic environment of Faculty and Students.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of magnetic writing board comprises the clipboard body, and said clipboard body is a cavity structure, is provided with many needles in the said cavity structure, and being full of around the said needle has opaque liquid, and the clipboard of said clipboard body is a transparent panel; Also be provided with the adsorbent equipment of absorption needle on the said clipboard body.
In order to realize the utility model better, on technique scheme, make further technological improvement below:
As preferably, above-mentioned needle is vertical with clipboard.
As preferably, above-mentioned adsorbent equipment is two-layer magnetic sheet, and said needle is between two-layer magnetic sheet.
As preferably, the N of above-mentioned all needles extremely near the S of clipboard or all needles extremely near clipboard.
As preferably, above-mentioned cavity structure is divided into the tiny dot matrix of a plurality of squares or a plurality of positive hexagons, is provided with a needle in each tiny dot matrix.
As preferably, above-mentioned transparent panel is that one deck glass plate is set on glass plate or the transparent panel.
As preferably, above-mentioned needle is provided with balancing stand.
In order better to use above-mentioned magnetic writing board, be the improvement made from the corollary equipment of wiping writing below:
A kind of magnetic writing pen that is used for above-mentioned magnetic writing board comprises nib, and said nib is the magnetic nib, and the N utmost point of magnetic nib or S be writing end very.
A kind of magnetic wiping board that is used for above-mentioned magnetic writing board comprises the wiping board body, and said wiping board body is provided with magnet, and the said magnets N utmost point or S be cleaning and polishing end very.
Compared with prior art, the beneficial effect of the utility model is:
In the technical scheme of the utility model, can on magnetic writing board, write easily, can wipe fast through the magnetic wiping board after having write through the magnetic writing pen; Do not need chalk, no dust pollution again easy to use can avoid the healthy of Faculty and Students to be endangered, and has improved academic environment.

The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of magnetic writing board comprises clipboard body 1; Said clipboard body is a cavity structure 2; Be provided with many needles 3 in the said cavity structure 2, being full of around the said needle 3 has opaque liquid 4, and the clipboard 5 of said clipboard body 1 is a transparent panel; Also be provided with the adsorbent equipment of absorption needle 3 on the said clipboard body 1.
Above-mentioned needle 3 is vertical with clipboard 5, and the S of all needles 3 is extremely near clipboard 5, and above-mentioned adsorbent equipment is two-layer magnetic sheet 6, and needle 3 is between two-layer magnetic sheet 6, and wherein magnetic sheet 6 has weak magnetic, and one deck magnetic sheet 6 is close on the inner surface of clipboard 5; Cavity structure 2 is divided into a plurality of foursquare tiny dot matrix 7, is provided with a needle 3 in each tiny dot matrix 7; One deck glass plate 8 is set on the transparent panel; Needle 3 is provided with balancing stand 9, and purpose is a balance needle 3, avoids distorting.
A kind of magnetic writing pen that is used for above-mentioned magnetic writing board comprises nib 10, and said nib 10 is a magnetic nib 11, and the N of magnetic nib 11 is writing end very.
A kind of magnetic wiping board that is used for above-mentioned magnetic writing board comprises wiping board body 12, and said wiping board body is provided with magnet 13, and the S of said magnet 13 is cleaning and polishing end very.
For fear of magnetic wiping board scratch glass, can be at cleaning and polishing end parcel one deck plastics of magnet 13.
Above-mentioned clipboard body 1 adopts plastic production.
When magnetic writing board write background when being black, for the ease of identification, needle 3 is painted with white towards an end of clipboard 5; Certainly needle 3 is coated other color of being convenient to distinguish towards an end of clipboard 5 and also can.
Facing the above-mentioned magnetic writing board and the operation principle of matching used magnetic writing pen and magnetic wiping board thereof down further describes:
Magnetic writing board is not when using, and needle 3 is adsorbed the back side that device is adsorbed on magnetic writing board, and do not have demonstration this moment on the magnetic writing board under the effect of opaque liquid 4; In use; The N of the magnetic nib 11 through the magnetic writing pen very writing end writes on the glass plate 8 of magnetic writing board, and after the S utmost point of needle 3 received the suction-operated of magnetic nib 11, needle 3 was to clipboard 5 motions; And be adsorbed on the magnetic sheet 6 of clipboard 5 inner surfaces; Because clipboard 5 is a transparent panel, the color of needle 3 obtains on clipboard 5 showing that the sliding path of magnetic writing pen forms font or figure.
In the time will wiping above-mentioned demonstration,, make the back side operation of needle 3 magnetropism clipboards, thereby arrive the purpose of wiping font or figure with the reverse magnetic pole of magnetic wiping board.
Structure and the operation principle of present embodiment and embodiment 1 are basic identical, and difference is:
Wherein the difference of magnetic writing board is that transparent panel directly adopts glass plate to make; The N of all needles is extremely near clipboard; Cavity structure is divided into the tiny dot matrix of a plurality of positive hexagons, is provided with a needle in each tiny dot matrix.
With the S of the magnetic nib of the supporting magnetic writing pen of magnetic writing board writing end very.
