Abstract
The invention relates to a novel magnet powder swimming writing board, characterized in that: it is composed of a writing core board, an elastic board and a magnet board, the baseboard of the writing core board is adjacent to the elastic board, the elastic board is adjacent to the magnet board, the layer number of the grids between the face board of the writing core board and the baseboard for separating write-display liquid is not less than 2 and not greater than 30, and the writing core board is a flexible core board, and the magnet board is made of permanent magnet or electromagnet. As writing, the writing core board and the magnet board are isolated by the elastic board, where the isolating space does not influence the handwriting of the writing core board; as erasing the handwriting, the writing core board is pressed to the magnet board and the writing core board and the elastic board near to force bearing point partially deform to make the part of the writing core board near to the force bearing point approach to the magnet board so that the magnet board acts on the magnet powder in this part to eliminate the handwriting.
Description
Technical field
The present invention relates to magnetic powder swimming type writing board.
Background technology
The central layer of writing of existing magnetic powder swimming type writing board is to be made of panel, grid, liquid and base plate.The magnetic writing board of prior art is divided into general grid clipboard and micro-capsulated magnetic clipboard, and the latter can not make colored liquid effectively hide magnetic because the diameter of microcapsules is limited, the background color depth, and remote writing shows unintelligible.The former enough makes colored liquid effectively hide magnetic owing to write the central layer trellis depth, the writing clear display, but prior art is produced, and to write central layer flexible poor, and erase mode mostly is back side magnetic stripe erase mode (U.S. Patent number 4143472 relates to), can not realize selective erase; China Patent No. 02113235, China Patent No. 99231331 relate to erase mode and have realized selective erase, but its common drawback is complexity of structure; The structure that China Patent No. 992096588 relates to is being write central layer and there is a magnetic sheet magnetic stripe back, because this patent does not relate to the improvement of central layer, the flexibility of the central layer that its prior art is made is poor, is not enough to the function that realizes that this patent relates to.The central layer that Chinese patent 200420033818.5 " magnetic writing board central layer " relates to has proposed a kind of brand-new network, but this patent has only realized the preceding good fit of the dress liquid of panel and base plate and grid.
Summary of the invention
The purpose of this invention is to provide a kind of novel magnetic powder swimming type writing board.
Novel magnetic powder swimming type writing board is characterized in that: clipboard is formed by writing central layer 1, elastic plate 2 and magnet plates 3, and the base plate 7 of writing central layer 1 is adjacent with elastic plate 2, and elastic plate 2 is adjacent with magnet plates 3; Write separate between the panel 6 of central layer 1 and the base plate 7 write show liquid the grid number of plies more than or equal to 2, be less than or equal to 30, writing central layer 1 is flexible central layer; Magnet plates 3 is permanent magnetism body or electromagnetism magnetic.
Advantage:
1,, when writing, writes clearance space that central layer 1 and magnet plates 3 separate because of elastic plate 2 and make the magnetic of magnet plates 3 not influence the writing of writing central layer 1 to write because to write central layer 1 be flexible; When writing is wiped, to write central layer 1 and press to magnet plates 3, write central layer 1 and the distortion of elastic plate 2 parts near the stress point, and make near the part of writing central layer 1 stress point near magnet plates 3, the magnetic of the magnetic action of magnet plates 3 in writing central layer 1 this part eliminated writing.Realized that easily local the or large-area writing of magnetic powder swimming type writing board wipes, the writing erase mode of its magnetic powder swimming type writing board is identical with the writing erase mode of existing blackboard, blank or green plate etc.
2, the clipboard central layer 1 that the present invention relates to has significant improvement on the basis of prior art 200420033818.5 " magnetic writing board central layer ", the principle of utilizing the cell of the separation liquid that this patent proposes to communicate, the sandwich construction of grid has been proposed, passage 9 changes the path 10 perpendicular to panel that the multi-layer net dislocation overlaps to form between the cell that is parallel to the panel direction that this patent is related to, or perpendicular to the path 10 of panel be parallel to the combination of the passage 9 of panel, or perpendicular to the path 10 of panel and be parallel to panel passage 9 and with the combination of the passage 11 of panel bevel, the good fit and the large tracts of land manufacturing of writing the central layer preceding grid of 1 dress liquid and panel and base plate have been solved effectively, the flexibility that has realized writing central layer 1 simultaneously.
