Description
Technical field
The utility model relates to a kind of blackboard eraser, a kind of specifically automatic dust-removing blackboard eraser.
Background technology
At present, in the teaching process of China, the teaching method that extensively adopts teacher on blackboard, to write still with chalk.Though some school has adopted multimedia teaching, also unavoidably can use blackboard.Though traditional wiping blackboard structure is simpler, form by a panel, felt or body brush are housed on the panel, but owing to there is not protector, can cause a large amount of dust from flying in use, teachers and students' health is caused very big harm, while is contaminated environment also, use also inconvenience, wasted manpower, wasted the time.Though have now and used dust-free chalk, just when writing, reduced Dust Capacity, when erasing the board, Dust Capacity is still very big, does not have basic dealing with problems.In order to overcome the big shortcoming of traditional blackboard crocus dust quantity, multiple dust-removing blackboard eraser has appearred now, but most complex structure, noise is bigger during use, and dust removing effects is undesirable, uses inconvenient.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in structure, and is easy to use, and noise is less, the automatic dust-removing blackboard eraser of good dedusting effect.
The purpose of this utility model can be achieved through the following technical solutions:
Automatic dust-removing blackboard eraser, comprise brush body, chute, chute is fixed on the blackboard both sides, and the brush body activity is fixed on the chute, and the brush body two ends respectively are provided with a driving gear and a driven gear, be provided with dust-collecting box in the middle of the brush body, the dust-collecting box upper end is provided with bristle brush wheel, and the dust-collecting box lower end is provided with the cloth wheel, and driving gear and brush body are rotationally connected, driving gear and driven gear engagement, driven gear is taken turns coaxial with bristle brush wheel, cloth.
The purpose of this utility model can also further realize by following technical measures:
Aforesaid automatic dust-removing blackboard eraser, the diameter of wherein said driving gear is greater than the diameter of driven gear.
Aforesaid automatic dust-removing blackboard eraser, the diameter of wherein said driving gear are the twices of driven gear diameter.
Aforesaid automatic dust-removing blackboard eraser, wherein said brush body two ends also respectively are provided with an idler gear, driving gear and idler gear engagement, idler gear and driven gear engagement.
Aforesaid automatic dust-removing blackboard eraser, wherein said dust-collecting box is connected with brush body is embedded.
Aforesaid automatic dust-removing blackboard eraser, wherein said dust-collecting box both sides are provided with draw-in groove or card article, and brush body is provided with the dust-collecting box hole, is provided with corresponding card article or draw-in groove in the dust-collecting box hole, and dust-collecting box embeds in the dust-collecting box hole.
Advantage of the present utility model is: the utility model cleans down most of letter written with chalk by bristle brush wheel, and dust directly enters dust-collecting box, by the cloth wheel all the other vestiges is removed then, reaches the purpose that cleans off a blackboard.Since be provided with bristle brush wheel and cloth wheel, better dust removal effect of the present utility model, and dust directly enters dust-collecting box, can not fly upward, and has effectively protected teachers and students' health.In addition, the utility model is simple in structure, comes transmission by two gears, does not use motor, and the noise of generation is less, uses also very convenient.
