Abstract
The utility model relates to blackboard for teaching, belongs to teaching aid field.A kind of chalk dust collecting device of blackboard, comprise blackboard, it is characterized in that: below blackboard, be provided with the groove for collecting chalk dust for collecting chalk dust, the surface of described groove for collecting chalk dust is set to porous groove face, porous groove face is arranged with the powder ash disposable box adopting drawer type to coordinate with porous groove face, porous groove face is also provided with a whole piece electrostatic brush bar from left to right near the plate face place of blackboard, described blackboard side is provided with blackboard eraser standing groove, and the blackboard eraser surface of cooperation adopts felt or fur material.The utility model adopts the coupling of porous groove face and powder ash disposable box, chalk dust is automatically collected in the process fallen in powder ash disposable box, and electrostatic brush bar is set in the side of laminating blackboard panel, can effectively be adsorbed on the chalk dust slowly dropped in writing process, blackboard eraser also carries out stronger absorption to the chalk dust produced during erasing blackboard, thus reduces flying upward of powder ash.
Description
Technical field
The utility model relates to blackboard for teaching, particularly relates to a kind of chalk dust collecting device of blackboard.
Background technology
In present classroom, blackboard generally has the platform being provided with in bottom to catch chalk dust and place blackboard eraser, but, due to situations such as the impacts in natural environment apoplexy, the chalk dust fallen not necessarily can just in time drop on platform, although therefore there is the platform collecting chalk dust, but in fact chalk dust is substantially all flying or fluttering in profusion, platform is difficult to collect most chalk dust substantially, chalk dust still can drift everywhere, unrestrained, not only cause drifting of chalk dust everywhere, and affect air and the ground environment in classroom, and the chalk dust on platform is also not easy cleaning, the chalk dust already dropped on platform all often can become secondary pollution source because of scale removal process.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chalk dust collecting device of blackboard, although solve present blackboard have platform, but not only cannot collect full chalk dust, affect air and the ground environment in classroom, but also the defect in secondary pollution source can be become because of the process of the chalk dust on cleaning platform.
Technical scheme
A kind of chalk dust collecting device of blackboard, comprise blackboard, it is characterized in that: below blackboard, be provided with the groove for collecting chalk dust for collecting chalk dust, the surface of described groove for collecting chalk dust is set to porous groove face, porous groove face is arranged with the powder ash disposable box adopting drawer type to coordinate with porous groove face, porous groove face is also provided with a whole piece electrostatic brush bar from left to right near the plate face place of blackboard, described blackboard side is provided with blackboard eraser standing groove, and the blackboard eraser surface of cooperation adopts felt or fur material.
Described electrostatic brush bar is arranged in hairbrush box, and the porous groove face of described groove for collecting chalk dust is provided with outstanding track, and described hairbrush box two bottom sides is provided with the draw-in groove bar clamping track with Orbit Matching, also adopts porous to arrange bottom described hairbrush box.
The porous groove face of described groove for collecting chalk dust is also provided with the upper cover of coupling.
Beneficial effect
The chalk dust collecting device of blackboard of the present utility model adopts the coupling of porous groove face and powder ash disposable box, chalk dust is automatically collected in the process fallen in powder ash disposable box, and the side of laminating blackboard panel is provided with electrostatic brush bar, can effectively be adsorbed on the chalk dust slowly dropped in teacher's writing process, the blackboard eraser adopting felt or fur material to make then can before use or utilize the electrostatic of frictional static hairbrush bar or alternate manner generation to carry out stronger absorption to the chalk dust produced during erasing blackboard in using, thus reduce flying upward of chalk dust to greatest extent, thus reach and thoroughly collect chalk dust, avoid the effect of airborne dust, the powder ash disposable box adopting drawer type to coordinate, make cleaning more convenient, and can not secondary pollution be produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-blackboard, 2-groove for collecting chalk dust, the porous groove face of 3-groove for collecting chalk dust, 4-powder ash disposable box, 5-electrostatic brush bar, 6-blackboard eraser standing groove.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
As shown in Figure 1, a kind of chalk dust collecting device of blackboard, comprise blackboard, the groove for collecting chalk dust for collecting chalk dust is provided with below blackboard, the surface of described groove for collecting chalk dust is set to porous groove face, porous groove face is arranged with the powder ash disposable box adopting drawer type to coordinate with porous groove face, porous groove face is also provided with a whole piece electrostatic brush bar from left to right near the plate face place of blackboard, described blackboard side is provided with blackboard eraser standing groove, and the blackboard eraser surface of cooperation adopts felt or fur material.Adopt electrostatic brush bar can be adsorbed on the chalk dust slowly dropped in teacher's writing process, the blackboard eraser adopting felt or fur material to make then can before use or utilize the electrostatic of frictional static hairbrush bar or alternate manner generation to carry out stronger absorption to the chalk dust produced during erasing blackboard in using, thus reduce flying upward of chalk dust to greatest extent, thus reach and thoroughly collect chalk dust, avoid the effect of airborne dust.And the powder ash disposable box adopting drawer type to coordinate, make cleaning more convenient, and can not secondary pollution be produced.
Described electrostatic brush bar is arranged in hairbrush box, and the porous groove face of described groove for collecting chalk dust is provided with outstanding track, and described hairbrush box two bottom sides is provided with the draw-in groove bar clamping track with Orbit Matching.So, electrostatic brush box can install or disassemble, and also adopts porous to arrange bottom hairbrush box, then the chalk dust adsorbed by electrostatic brush bar also slowly can fall in the powder ash disposable box of below in adsorption process, is easy to cleaning.Adopting detachable hairbrush box, is also conveniently thoroughly can clear up chalk dust.
The porous groove face of described groove for collecting chalk dust is also provided with the upper cover of coupling.When blackboard infrequently uses, just upper cover can be covered, avoid the dust of electrostatic brush bar always in absorbed air, affect the adsorption effect of chalk dust.
