Description

Dust-free environmental protection type blackboard
Technical field
The present invention relates to a kind of teaching aid, i.e. dust-free environmental protection type blackboard.
Background technology
In prior art, traditional blackboard is glued board or glass-board surface, and chalk dust is arranged when wiping font, contaminated environment, harm teachers and students health.Dust-free environmental protection type blackboard also has numerous patent applications, but structure is different, and complicated and simple differing is difficult to apply.
Summary of the invention
The objective of the invention is provides a kind of result of use better dust-free environmental protection type blackboard at above-mentioned deficiency.
Technical solution of the present invention is: dust-free environmental protection type blackboard comprises framework, the board face.Be provided with at least one pair of upper and lower band roller on framework, be wound with the board face between the upper and lower band roller, one of them band roller is the drive roll of driven by motor, realizes that the plate face moves.Portion's broad ways is provided with the water spout that at least one row directly impacts the radiation water spray of chalk writing in face of the board, and the hydro-peening area is big, can directly wash out font on the plate face with press water; The water receiving case is arranged at the water spout bottom, and the water receiving case connects a water container, and circulating pump is connected with water container with the water spout pipeline, realizes that flush water recycles.The board face is preferably the black rubber offset plate, but is not limited thereto, along with the development of technology, only however suction, not reflective, non-slip, can twine, on-deformable plate face all can.Forward the horizontal suction roll that has been sticked before the board face surface at rear portion to, the suction roll surface is wound with the towelling of easy suction, residual water on the plate face is loose as early as possible do.
Advantage of the present invention is: 1, blackboard panel can electronicly up and down move, and the teacher can write letter written with chalk in the optimum position.The teacher selects to write word location on the blackboard according to own characteristic, need not be eager to wipe, write when full the Push switch plate face that just can move up, can continue to write, letter written with chalk is in conspicuous position, and structure is indeformable, retention time is long, and the teacher writes conveniently, and the student also need not record the note to influence and listen to the teacher because of being eager.2, a press water spray dry linting writing, the hydro-peening area is big, realizes " wiping " blackboard automatically, and writing goes totally.In the time of need wiping letter written with chalk, press and wipe switch, whole letter written with chalks just can be wiped automatically in water spray back, wipe thorough and do not have vestige.3, no chalk dust, protection Faculty and Students health.Blackboard has chalk dust depositing dust processing capacity, automatically dust is washed when erasing the board, and concentration of transmissions is concentrated easily and removed the chalk sediment to dust absorption plant (water container), realizes no dust and non-environmental-pollution.If the teacher writes with special-purpose shaft of a writing brush dress chalk, can also reach hand does not have dust, is very beneficial for Faculty and Students' health.4, structure of the present invention is more reasonable, and is simpler, easy to use, and result of use is good, is beneficial to environmental protection.
Description of drawings
Accompanying drawing is a structure diagram of the present invention.
Below in conjunction with embodiment embodiments of the present invention are described in further detail.
The specific embodiment
Dust-free environmental protection type blackboard comprises framework 1 (stainless steel), board face 2.On framework 1, be provided with upper and lower band roller 3,4, be wound with board face 2 between the upper and lower band roller 3,4, on be the drive roll that motor 10 drives with roller 3.Upper and lower band roller is at least a pair of, also be many to or a plurality of, increase board 2 time of staying of face, can dry after more convenient board face 2 washings.Be provided with the water spout 5 of at least one row's radiation water spray in board face 2 lower front portion broad ways, water spout 5 structures are as on the market the rose of watering flowers, the imaginary circle area among the figure for spray towards scope, be beneficial to the removal writing especially.There is water receiving case (groove) 6 water spout 5 bottoms and encases water spout 5.Circulating pump 7 is connected with water container 9 (as bucket) with water spout 5, and convenient collection chalk sediment can show the water yield in the water container 9 simultaneously, recycles the conserve water resource.
Water container 9, circulating pump 7 can be supporting one group of blackboards, also can be systems, shared one or several water container 9 of a plurality of blackboards, circulating pump 7.Water container 9, circulating pump 7 can not be placed in the classroom, are placed on another place, reduce noise, neat rule.Forward the horizontal suction rolls 8 that have been sticked before board face 2 surface at rear portion to, along the 2 width settings of board face, can freely turn round, suction roll 8 is the towel roller, and the water on 2 in the easy adsorption writing board face is convenient to board face 2 and is dried as early as possible, is convenient to write once more.
Framework 1 is provided with board face 2 and moves up and down switch, circulating pump 7 switches.
Using method: the writer writes full word in its arm reach after, press board face 2 and move switch, board face 2 can more than move, expose new plate face, can continue to write, write full up to whole plate face, start circulating pump 7 switches, move switch by board face 2 again, board face 2 moves down, font on the board face 2 before the water spout 5 is washed away by water, realizes " wiping " blackboard.Board face 2 forwards to behind the back side again through the residual water of suction roll 8 absorption surfaces, is more conducive to dry, and waits when being recycled to the front and can write font again.
