Description
Technical field
The present invention relates to a kind of blackboard with automatic blackboard eraser, especially relate to a kind of automatic blackboard control device.
Background technology
Existing blackboard eraser is to be made by the material of loading onto felt one class above plank and easily wipe letter written with chalk.When erasing the board, although letter written with chalk has been wiped, chalk dust flies upward everywhere, the hand of making dirty, clothes and face.Arm moves in turn back and forth owing to erasing the board, also sweat very, in addition, when moving in turn back and forth, also strengthen Air Flow, made the farther of diffusion that dust wafts, contaminated environment, long-term suction dust is very unfavorable to student and teacher's physical and mental health, and dust from flying is very unhygienic simultaneously, and the existing blackboard eraser life-span is short, waste of material is serious, does not meet the theory of national energy-saving environmental protection.
Although also have in the market much can dust suction blackboard eraser, as the Chinese patent application that application number is 98226023.7 has been recorded a kind of ash-collecting blackboard eraser, wherein, between dust catcher and blackboard eraser, by one section of hose, be connected, although this blackboard eraser reaches certain effect, but because blackboard eraser will various piece will move use on large area blackboard, the hose of single length is made troubles to using, depositing, ash-collecting blackboard eraser self structure is complicated simultaneously, cost is high, and easily stops up flexible pipe.
Application for a patent for invention numbers 201310153790.2,2013.07.17, a kind of intelligent blackboard system is disclosed, comprise: blackboard panel, top sidewall and the bottom sidewall of blackboard panel are respectively arranged with track, are provided with tooth bar in track, in a rack and pinion engagement platform, are provided with large pinion, rack and pinion engagement platform meshes by pinion and gear wheel, and gear wheel meshes with described tooth bar again; Blackboard eraser housing, in blackboard eraser housing, be provided with dust block board, dust block board is provided with felt near a side of blackboard panel, the opposite side of dust block board is provided with motor and the shaft coupling being connected with motor, pinion is connected with shaft coupling by a little axle, and gear wheel is connected by another macro-axis by bearings.On the top sidewall of blackboard eraser housing and bottom sidewall, be provided with groove; Be arranged at the tourelle on tooth bar, on tourelle, be fixed with pin, each pin respectively with the top sidewall of blackboard eraser housing and the engagement on the sidewall of bottom.Though it can remove the font on blackboard automatically, cleanly, complex structure, manufacturing cost is high, and automaticity is low, should not promote the use of.Therefore, need a kind of blackboard and control device with automatic blackboard eraser
Summary of the invention
The present invention will provide a kind of automatic blackboard control device, the blackboard eraser that this device can be controlled in automatic blackboard is automatically disposed required font of wiping on blackboard body etc., easy to use, automaticity is high, and elimination efficiency is high, simple in structure, be convenient to promote the use of.
For achieving the above object, technical scheme of the present invention is: a kind of automatic blackboard control device, comprise motor, writing detector, inhale apparatus for ash, controller, power supply, controller signals input connects writing detector, for receiving writing detector, survey the writing signal of required removing on blackboard, controller drive output connects respectively the first motor, the second motor and suction apparatus for ash, according to writing detector, surveying the writing signal of required removing on blackboard controls respectively on driving blackboard eraser cross bar, lower movement, blackboard eraser slide is left, removing writing moves right, starting is simultaneously inhaled apparatus for ash and is inhaled ash.
Writing detector is arranged on blackboard eraser slide.Inhaling apparatus for ash is arranged on respectively on blackboard eraser slide lower surface and blackboard lower surface.
The beneficial effect that the present invention compared with prior art has is: by control device of the present invention, can realize automatic blackboard and automatically remove the font on blackboard, when writing detector detects after required font of wiping etc., upper left by motorized motions blackboard eraser, move right, just required font of wiping on blackboard body etc. can be disposed cleanly, lower end, blackboard eraser slide rear portion is provided with dust-absorbing mouth, and on dust-absorbing mouth and suction apparatus for ash connected sum blackboard body lower surface, ash absorbing hole is set, solved the blackboard eraser of prior art when wiping chalk word, chalk dust but flies upward everywhere, the hand of making dirty, clothes and face.And the arm technical problem of sweat that moves in turn back and forth while erasing the board, and have easy to use, laborsaving, elimination efficiency is high, the feature such as simple in structure, be convenient to promote the use of.
