Description

Automatic dust-free blackboard is wiped

(1) technical field:

The utility model relates to a kind of teaching aid, and particularly a kind of healthy Automatic dust-free blackboard of teachers and students that guarantees is wiped.

(2) background technology:

Teacher goes up class hour now, middle and primary schools particularly, the blackboard that mostly also is to use adds chalk and adds teacher again and impart knowledge to students face-to-face, when teacher erases the board on class, no matter use common chalk or dust-free chalk, because the ability that the existing extensive blackboard brush that uses is not collected dust, chalk dust just causes very big dust pollution to the classroom, the dust pollution of the generation that erases the board after teacher's writing on the blackboard is intact to self, student's health all causes great harm.

(3) summary of the invention:

It is a kind of easy to use that the purpose of this utility model is to provide, and dust-absorbing strength is strong, and Automatic dust-free blackboard that can automatic blackboard cleaning is wiped.

The technical scheme that adopts is as follows:

Automatic dust-free blackboard is wiped, comprise blackboard eraser housing, two roll brush, infrared receiver, remote controller and dust catchers, blackboard eraser housing one side is provided with the wiping mouth, be set with the sealing adhesive tape on the periphery mouthful wall of wiping mouth, the inboard of sealing adhesive tape is positioned on the periphery mouthful wall of wiping mouth and is set with magnet.Parallel vertical is equiped with two turning cylinders respectively in the wiping mouth, two roll brush fixed cover respectively are located on two turning cylinders, be set with two motor respectively on two turning cylinder tops, and two motor are fixedly installed on respectively in the blackboard eraser housing, fixedly connected with the output shaft of two motor respectively in the upper end of two turning cylinders.Vertical fixing is provided with dividing plate in the blackboard eraser housing and between two turning cylinders.Top in the blackboard eraser housing is set with battery, and infrared receiver is fixedly installed on the rear end face of blackboard eraser housing.Be set with netted magnet on the rear end face of blackboard, the wiping mouth of blackboard eraser housing be located on the blackboard.The lower surface of blackboard eraser housing is provided with suction port, and suction port is fixedly connected with hose, and the other end of hose is connected with dust catcher.

Be equiped with alignment pin by desired location respectively on the lower surface of above-mentioned blackboard eraser housing, be respectively equipped with the alignment pin jack on two turning cylinder lower surfaces, alignment pin can be plugged in the alignment pin jack when having a power failure, and two turning cylinders are fixed can manual blackboard wiping.

The utility model is pressed remote controller buttons infrared receiver received signal in use, and the roll brush of a side is rotated, and drives the blackboard eraser housing and laterally move on blackboard in blackboard wiping.The blackboard eraser housing laterally moved on blackboard round about when equally, the opposite side roll brush rotated.

The utlity model has following advantage: rational in infrastructure, be skillfully constructed, use this blackboard eraser, the classroom air has obtained purification, helps the healthy of Faculty and Students, also helps environmental protection simultaneously.
