Abstract
The utility model relates to a full-automatic blackboard eraser. The full-automatic blackboard eraser comprises a rectangular blackboard eraser shell, a cylindrical eraser body unit, a motor unit and a power supply unit, wherein the cylindrical eraser body unit is arranged in the shell; the motor unit and the power supply unit are used for driving the eraser body unit to rotate; and the motor unit drives the cylindrical eraser body unit to rotate, so that bristles on the eraser body can remove the writing of chalk. Compared with the prior art, the full-automatic blackboard eraser is novel in design, practical in function, convenient to operate, automatically and effectively erase off chalk ashes, and prevents the chalk ashes from being scattered anywhere, so that the labour is saved, and the health of people is benefited.
Description
Technical field
The utility model relates to a kind of teaching aid, more particularly, relates to a kind of blackboard eraser.
Background technology
Ordinary blackboard eraser usage comparison effort, erase process need to be pressed blackboard eraser and firmly be brandished on blackboard, and the time one, arm of a specified duration can acid.In addition, the erase process chalk dust of can kicking up, chalk dust not only can be the hand of making dirty, and can be unhealthful after sucking.
The utility model content
In view of the problem that prior art exists, the purpose of this utility model provides a kind of blackboard eraser, and it can be wiped automatically, can draw the chalk dust that erase process is kicked up simultaneously.
In order to address the above problem, the utility model adopts following technical scheme: a kind of automatic blackboard eraser comprises rectangle blackboard eraser housing, is arranged on the tubular rub body unit in the housing, electric motor units and the power subsystem of driving rub body unit rotational.Electric motor units drives tubular rub body unit rotational, thereby the bristle on the rub body unit can be removed chalk writing.
In one embodiment, described tubular rub body unit arranges perpendicular to the long limit of blackboard eraser housing.
In another embodiment, described tubular rub body unit is parallel to the long limit of blackboard eraser housing and arranges.
Described tubular rub body unit has 1-3, and preferably, described tubular rub body unit has 2.
In order to prevent that chalk dust from flying away everywhere, described automatic blackboard eraser also comprises the dust suction unit.Described dust suction unit comprises blower fan, suction port and chalk dust accommodating chamber, and blower fan is arranged in the blackboard eraser housing, and the dust suction choma is located at the periphery of blackboard eraser housing.Thereby when tubular rub body cell erasure chalk writing produced chalk dust, chalk dust was sucked the chalk dust accommodating chamber by suction port by blower fan.
In one embodiment, described power subsystem is lithium battery.
In another embodiment, described power subsystem is dc source.
Than prior art, automatic blackboard eraser of the present utility model, modern design, practical function, easy to operate can be automatically and erasing chalk ash efficiently, prevent that simultaneously chalk dust from flying away everywhere, save manpower and also are conducive to health.
Description of drawings
Fig. 1 is the schematic diagram of automatic blackboard eraser of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, a kind of automatic blackboard eraser comprises rectangle blackboard eraser housing 10, is arranged on the tubular rub body unit 20 in the housing, electric motor units 30 and the power subsystem 50 that driving rub body unit 20 rotates.Electric motor units 30 drives tubular rub body unit 20 and rotates, thereby the bristle on the rub body unit 20 can be removed chalk writing.Described tubular rub body unit arranges perpendicular to the long limit of blackboard eraser housing.Described tubular rub body unit has 2.Described automatic blackboard eraser also comprises dust suction unit 40.Described dust suction unit 40 comprises blower fan 410, suction port 420 and chalk dust accommodating chamber 430, and blower fan 410 is arranged in the blackboard eraser housing 10, and suction port 420 rings are located at the periphery of blackboard eraser housing.Thereby when tubular rub body cell erasure chalk writing produced chalk dust, chalk dust was sucked the chalk dust accommodating chamber by suction port by blower fan.Described power subsystem 50 is lithium batteries.
