Description
technical field
The utility model relates to a kind of realia, especially a kind of Automatic erasing blackboard.
background technology
The Automatic erasing blackboard kind existing is in the market a lot, also occurred the blackboard similar with this equipment, they use motor, wiper rail, blackboard to combine, and make the upper and lower wiping of wiper rail or left and right wiping simultaneously, the mode of these blackboard-cleanings is more single, and its efficiency is lower.On classroom, can not to blackboard, carry out wiping quickly, thereby can not make classroom high efficiency running.
Utility model content
The utility model is intended to address the above problem, and a kind of Automatic erasing blackboard is provided, and it has overcome, and manpower blackboard wiping is wasted time and energy and the inefficient drawback of automatic erasing, and its technical scheme adopting is as follows:
An Automatic erasing blackboard, comprises blackboard body, entablature, sill, rectangle blackboard eraser, the rotatable wiper of a plurality of circle, chalk powder disposable box, air suction device, motor, muffler, belt, gear and switch; Described entablature and sill lay respectively at the top and bottom of blackboard body, described rectangle blackboard eraser is slidably connected with entablature and sill, described blackboard eraser is provided with the rotatable wiper of a plurality of circles, and two rows that are distributed as that described wiper smears at rectangular slab are staggered successively; Described air suction device is positioned at the left and right sides of blackboard body, and is connected with chalk powder disposable box, and the length of described air suction device is identical with the length of blackboard eraser, and described air suction device is provided with sense of touch inductor; Described motor is fixed on blackboard rear side, for blackboard eraser provides power along the moving left and right of entablature and sill, the rotation of wiper and the startup of air suction device; Described muffler is arranged on motor, and motor is carried out to noise reduction; Described gear combines with belt, utilizes the power that motor provides to complete motion, and described switch is positioned at the bottom of blackboard body, and one end is connected with motor, and the other end is connected with gear.
The utlity model has following advantage: simple in structure, make full use of blackboard eraser move left and right and these two kinds of wiping modes that rotatablely move of wiper are carried out wiping to blackboard, improved greatly wiping efficiency, solved the drawback that manpower blackboard wiping is wasted time and energy; Utilize air suction device to reclaim chalk powder, deposit in chalk powder disposable box, avoided chalk powder to be sucked by human body; Utilize silencing means to carry out noise reduction to motor and various motion, for academics and students provides a quiet academic environment.

the specific embodiment
As depicted in figs. 1 and 2, Automatic erasing blackboard of the present utility model, comprises blackboard body 1, entablature 2, sill 3, rectangle blackboard eraser 4, the rotatable wiper 5 of a plurality of circle, chalk powder disposable box 6, air suction device 7, motor, muffler, belt, gear and switch 8.
Described entablature 2 and sill 3 lay respectively at the top and bottom of blackboard body 2, described rectangle blackboard eraser 4 is slidably connected with entablature and sill, described blackboard eraser 4 is provided with the rotatable wiper 5 of a plurality of circles, two rows that are distributed as that described wiper smears at rectangular slab are staggered successively, thereby can cover whole blackboard surface; Described air suction device 7 lays respectively at the left and right sides of blackboard body, and be connected with chalk powder disposable box 6, the length of described air suction device is identical with the length of blackboard eraser, described air suction device is provided with sense of touch inductor 9, when blackboard eraser touches sense of touch inductor, air suction device can start, and the powder of adhesion on blackboard eraser is sucked to chalk powder disposable box.
Described motor is fixed on blackboard rear side, for blackboard eraser provides power along the moving left and right of entablature and sill, the rotation of wiper and the startup of air suction device; Described muffler is arranged on motor, and motor is carried out to noise reduction; Described gear combines with belt, utilizes the power that motor provides to complete various motions, and described switch 8 is positioned at the bottom of blackboard body, and one end is connected with motor, and the other end is connected with gear.
During use, press switch, motor start-up, by gear and belt, drive rectangle blackboard eraser to move from left to right or motion from right to left, the rotatable wiper of a plurality of circles in blackboard eraser is rotated simultaneously, carries out blackboard wiping, has improved greatly wiping efficiency.When wiping is complete, rectangle blackboard eraser moves to a side of blackboard body, touches sense of touch inductor, now blackboard eraser stop motion, and air suction device starts, and the powder of adhesion on blackboard eraser is sucked to chalk powder disposable box, after 10s, air suction device quits work automatically.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
