Description
Technical field
Blackboard with electronic dust-absorbing blackboard brush described in the utility model, relate to a kind of school supply and stationery, is specially the blackboard with the dust adsorption blackboard brush.
Background technology
As everyone knows, blackboard is teacher's one of indispensable teaching aid of imparting knowledge to students, and the healthy of teacher in the chalk dust serious threat, although many dust-free chalks appear in market now, but blackboard eraser still can evoke a large amount of dust.Thereby and not yet there is a kind of dust emission that can really alleviate to reduce the effective product of dust to the harm of teacher's health at present.For existing problem in above-mentioned prior art, a kind of novel blackboard with electronic dust-absorbing blackboard brush of research and design, be very necessary thereby overcome existing problem in prior art.
Summary of the invention
In view of existing problem in above-mentioned prior art, the purpose of this utility model is a kind of novel blackboard with electronic dust-absorbing blackboard brush of research and design, to reduce the discharge of dust, alleviates the harm to teacher's health.
Technical solution of the present utility model is achieved in that
Blackboard with electronic dust-absorbing blackboard brush described in the utility model; It is characterized in that blackboard a sideslip bar respectively is housed up and down, two perpendicular slide bars that can slide on the sideslip bar are being housed on the sideslip bar, on perpendicular slide bar, electric blacboard eraser with chalk dust absorbing moving up and down is housed; Handle is housed on electric blacboard eraser with chalk dust absorbing.
Electric blacboard eraser with chalk dust absorbing described in the utility model is comprised of power supply and motor, pinion, gear wheel, brush axle, housing, axle, fan, detachable water box and agitator; Power supply and motor are loaded on the top of housing, on the output shaft of power supply and motor, axle are housed; Pinion is equipped with on top at axle, and pinion is meshed with two gear wheels, and the brush axle is housed on gear wheel, and the bristle of spiral winding is housed on the brush axle; Detachable water box is housed in the bottom of housing, and axle is inserted in detachable water box, on the axle of the oral area communicated with housing near detachable water box, fan is housed; Agitator is equipped with in lower end at axle; Switch is equipped with in the outside at housing.
Fan described in the utility model rotates under the drive of power supply and motor, produce the suction to detachable water box.
Housing described in the utility model is processed with opening near blackboard one side, makes bristle to contact with the blackboard extruding.
Opening power during use, motor rotarily drives pinion, fan and agitator rotation, pinion drives two gear wheel rotations, gear wheel drives brush axle and bristle rotation, bristle starts blackboard wiping, the suction to detachable water box that chalk powder under wiping is produced by fan is drawn in detachable water box, dissolves in water by the stirring of agitator.Blackboard eraser of the present utility model can freely move up and down on perpendicular slide bar, perpendicular slide bar also can move left and right the sideslip bar is cofree, makes blackboard brush move freely on the blackboard plane.
The utility model has the advantages that apparently, be mainly manifested in:
1, use the utility model, can to greatest extent the dust on blackboard be drawn in detachable water box, reduced the suction of teachers and students to dust;
2, because the utility model is stirred into dust in water, the secondary pollution of dust;
The utlity model has novel structure, processing easy, easy to use, with low cost, reduce to pollute, reduce the advantages such as injury of dust to human body, it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
