Description
Technical field
The present invention relates to blackboard apparatus field, the family that especially a kind of common chalk, dust-free chalk, water-color paintbrush are write is black
Plate.
Background technique
Blackboard is generally used made of plank or ground glass etc., can be write with the specific writing material such as chalk above
Word.Mostly black, blackish green, white or ecru.But many chalk dusts will cause using chalk-writing, it is strong to influence human body
Health, meanwhile, using dust-free chalk, water-color paintbrush write, although the problem of can solve dust, the personnel of generally requiring go it is erasable,
Workload unnecessary is brought in this way, wastes many times.
Summary of the invention
It is an object of the invention to overcome the technical problem present on, it is black to provide a kind of family with communication function
Plate.
To achieve the above object, the technical scheme is that in the following manner realizing:
Family's blackboard that a kind of common chalk, dust-free chalk, water-color paintbrush are write, including the installation of the blackboard body back side described in blackboard body
There are dust catcher and driving motor, the bottom of blackboard body is provided with the slot that gathers dust, rolling rod is installed in blackboard body two sides, institute
It states rolling rod and is equipped with soft brush, the rolling groove that rolling rod rolls around is offered on the top of blackboard body and bottom, black
It is equipped on the left of plate ontology and rolls lever switch and vacuum cleaner switch；The rolling lever switch connects the driving motor, to
Driving rolling rod is rolled around along rolling groove level, and the vacuum cleaner switch connects dust catcher, for starting dust catcher work.
Further, the rolling rod is two, respectively at left and right sides of blackboard body.
Further, dust collecting sleeve is connected with below the slot that gathers dust.
Further, also covering in the blackboard body has shield.
Further, LED illumination lamp is also equipped in the blackboard body.
The present invention realizes automatic erasable blackboard, passes through dust suction by rolling rod and the soft brush being arranged on rolling rod
Device and the slot that gathers dust can receive chalk dust, solve dust problem existing for traditional chalk-writing.
Detailed description of the invention
Fig. 1: structural schematic diagram of the invention.
Specific embodiment
