Description
Technical field
The present invention relates to a kind of magnetic wordpad, particularly utilize magnetic principles to supply children's write and draw a picture board of usefulness, belong to a kind of educational aid.
Background technology
The magnetic wordpad that more kind is also arranged at present on the market; These magnetic wordpads write or draw a picture on the board core of board through magnetic pen; The magnetic of board in-core is adsorbed onto the upper surface of board core through magnetic pen; Thereby the upper surface at the board core demonstrates literal or picture, when needs are removed the literal be positioned on the board core upper surface or picture, streaks at the lower surface of board core through demagnetization mechanism and to get final product; So just can the magnetic that originally was adsorbed to board core upper surface be fallen back to the lower surface of board core, thereby reach the purpose of eliminating originally word that write out with magnetic pen or the figure that draws.
For example, open day is on October 05th, 2011, and publication number is in the Chinese patent of CN201998666U; Disclose a kind of magnetic absorption environmental protection board, backing plate has been housed in framework, cylinder and bottom roll have been installed respectively in the top and the bottom of framework; On last cylinder and bottom roll, be set with the ring-shaped magnetic door curtain made of cloth; Drive unit is installed on bottom roll and is provided with stock chest, in stock chest, be loaded with the ferrotianium particle, in stock chest, be respectively equipped with scraper plate and brush bar; The constant force tensioning apparatus is installed on the last cylinder, and framework surface on one side is provided with gauge tap, and this gauge tap links with the controller that is installed in the framework inner chamber, and controller links through lead and drive unit, upper limit position switch and lower position switch.The complex structure of this magnetic absorption environmental protection board, operation inconvenience, production cost is high.
And for example, open day is 03 month 21 days calendar year 2001, and publication number is in the Chinese patent of CN2424021; Disclose a kind of magnetic control board, this magnetic control board is made up of board, the wiping of plate panel, fixed border, magnetic writing pen, and board is contained on the substrate; Substrate is equipped with slideway in two limits up and down; The blackboard eraser cursor slide is installed on the substrate up and down slideway by the slideway folder on the roller box up and down, and the plate panel is wiped and is contained on the U-shaped slide bar; On the roller box, the plate panel had smeared control knob about U-shaped slide bar two ends were separately fixed at.The portion of the handle that the plate panel is wiped in this magnetic control board exposes outside fixed border, causes the outward appearance of board not attractive in appearance, and the inconvenience that resets of plate panel wiping, causes the use inconvenience of magnetic control board.
Though the kind of existing magnetic wordpad is more,, can there be following some deficiency usually in existing magnetic wordpad: 1, the shell of board all is the plastic casing of injection molded usually, and a style need be opened a secondary mould, and production cost is quite high.2, demagnetization structure mainly comprises the slide bar that has magnetic stripe, and the Handheld Division of this slide bar is exposed at the outside of housing, during use, one side slide bar is from the another side that slides into of board; Thereby reach the purpose to the board demagnetization, on the one hand, the Handheld Division of slide bar is exposed at the outside of housing, causes the outward appearance of board not attractive in appearance; On the other hand, resetting means is not set in the demagnetization mechanism, causes the inconvenience that resets of demagnetization mechanism, in addition; During with hand slip slide bar, active force mainly acts on an end of slide bar, because slide bar self is longer; Cause slide bar when sliding, can often block, operation is not very flexible, thereby greatly reduces the quality of board.3, magnetic wordpad is mainly used to single writing or drawing a picture, and function and usage is concentrated inadequately, makes troubles to the user, has dwindled applicable surface.4, the phenomenon of leakage of oil in use may appear in the board core; And effective hermetically-sealed construction is not set between board core and the plastic casing; In case the phenomenon of board core leakage of oil occurs; Will cause the magnetic wordpad leakage of oil, thereby influence the use of magnetic wordpad greatly, the oil stain that leaks out may work the mischief to children.5, overall appearance is not attractive in appearance, and the back side of magnetic wordpad is uneven, easily human body is produced injury; In addition, plastic cement products on the one hand service life shorter, fragilely on the other hand hurt children.
A kind of simple in structure, reasonable in design owing to also not having at present, dependable performance, simple to operate, easy to use, the magnetic wordpad that production cost is low.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, dependable performance, simple to operate, easy to use, the magnetic wordpad that production cost is low.
