The blackboard that teaching is at present used can be divided three classes basically: chalk with blackboard, blank pen with blank, magnetic pen blank.Owing to use chalk to write, wipe, and causes dust pollution easily, influences health by the felt brush with blackboard for chalk.And the blank pen has carried out dustless improvement with blank, but consumes greatly, and price is high, is difficult to promote.Magnetic pen of the prior art is some iron powders of placement below clipboard with blank basic structure, utilize bar magnet to demonstrate mobile track on the clipboard bottom surface mobile iron powder is adsorbed on the clipboard, in the time of need wiping iron powder, re-use one and place the floating rule of clipboard bottom surface that iron powder is scraped off.Though dustless, the no consumption of this blackboard still has the following disadvantages: 1. this kind clipboard can only use under its flat presentation, otherwise iron powder can be according to the heavy downside that gathers at clipboard of gravity, and can't use; 2. iron powder easily disperses to cause writing unintelligible; 3. owing to being to adopt floating rule to slide to wipe, so the arbitrary written portion of wiping indiscriminately ad. as one wishes is not suitable for classroom instruction.
The utility model content
Technical problem to be solved in the utility model provides a kind of magnetic grain blackboard of freely wiping of carrying out, and utilizes the interaction principle of magnetisable material 5, solves the problem that existing magnetic blackboard can't freely be wiped.
For achieving the above object, the utility model provides a kind of magnetic grain blackboard of freely wiping of carrying out, comprise plate body 1, magnetic blackboard eraser 3 and magnetic pen 2, wherein plate body 1 is two transparent laminated planks for having one deck at least, be provided with sealing grid 4 in the clamping plate, magnetic blackboard eraser 3 and magnetic pen 2 are made by magnetic material; It is characterized in that: the coloured magnetisable material 5 of filling in the described sealing grid 4, described magnetisable material 5 is different with magnetic pen 2 tip of the brushstyle of a writing or painting polarity, and is identical with the polarity on blackboard eraser 3 surfaces.
The magnetic grain blackboard that above-mentioned carried out freedom is wiped is characterized in that, described sealing grid 4 is a honeycomb arrangement.
Technique effect of the present utility model is:
1, dustless, non-environmental-pollution is beneficial to the healthy of teachers and students;
2, low consumption, energy-saving and emission-reduction, compliance with environmental protection requirements;
3, arbitrarily wipe, be fit to the use of giving lessons of teacher classroom;
4, writing is clear, and is not yielding, durable.
Description of drawings
Fig. 1 is structure of the present utility model and uses schematic diagram;
The specific embodiment
Further describe specific embodiment of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises plate body 1, magnetic blackboard eraser 3 and magnetic pen 2.
Wherein, plate body 1 is two transparent laminated planks for having one deck at least, is provided with sealing grid 4 in the clamping plate, and can be once, compacting forms.Sealing grid 4 can be by going line by line anyhow or arranging or press honeycomb arrangement by interventricular septum.All closely arrange the chamber, cave, and the arrangement mode that interval is each other dwindled as far as possible all is desirable.But the interactional arrangement mode of the particle that can as far as possible deperm should preferentially be adopted.Wherein alveolate texture is the most rational arrangement mode, and the periphery the when particle that can deperm effectively like this rotates disturbs.
Shown in Fig. 1-a, charge completely coloured magnetisable material 5 in the described sealing grid 4, can be that itself is coloured or on the make paint.Described magnetisable material 5 is white oil and the permanent magnetic iron powder particle of barium suspension, and the permanent magnetic iron powder particle of described white oil and barium suspension ratio is 2～3: 1.
Magnetic blackboard eraser 3 and magnetic pen 2 are made by magnetic material.Magnetisable material 5 in the described sealing grid 4 is different with magnetic pen 2 tip of the brushstyle of a writing or painting polarity, and is identical with the polarity on blackboard eraser 3 surfaces.
During use, utilize the interaction principle of magnetisable material 5, shown in Fig. 1-b, the magnetic particle in the plate body 1 is adsorbed under the blackboard transparent thin board surface, by the aberration demonstration writing of magnetic particle and plate body 1 by magnetic pen 2.Shown in Fig. 1-c, the surface polarity of magnetic blackboard eraser 3 is identical with magnetic particle polarity, in wiping process magnetic particle is pushed plate body 1, and writing can disappear.Because the suspension of the permanent magnetic iron powder particle of barium in white oil gathered, thus be subjected to can to carry out flexibly under the extraneous magneticaction, displacement accurately, be attached under the blackboard transparent thin board, demonstrate the clear preferably writing of continuity.And the density ratio between the permanent magnetic iron powder particle of white oil and the barium suspension is 2～3: 1, has left blackboard even guaranteed magnetic pen 2, and the permanent magnetic iron powder particle of barium still can stably keep corresponding position and state, avoids occurring phenomenons such as writing displacement.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all contained by claim of the present utility model.
