Description
Technical field
The utility model relates to a kind of automatic blackboard eraser suction box, belongs to teaching aid, particularly relates to the blackboard eraser suction box that blackboard eraser suction scrubbing combines.
Background technology
Traditional chalk or blank pen are adopted in writing of modern teaching plate or board, chalk is write the back and is wiped with traditional blackboard eraser, wipe generation chalk ash pollution the teaching in classroom environment, endanger the healthy of numerous teachers and students, and instruments used for education and educational technology equipment brought infringement; The blank pen is the type ink with an organic solvent, owing to can only write on smooth surface, clipboard is reflective easily, is subjected to significant limitation so use, simultaneously, the blank pen write the back exist wipe difficult, use cost is high, distribute the poisonous penetrating odor etc. that has.
Also have a kind of writing on the blackboard pen, adopt aqueous ink, write the mode that wet rubbing is used in the back, wipe and do not produce dust, but blackboard eraser suction troublesome poeration, and after repeatedly wiping, the residue of blackboard eraser savings is too much, causes writing to be difficult for wiping, and the plate face is wiped unclean.At present, use the writing on the blackboard pen of wet rubbing mode not have supporting suction and cleaning device.
The utility model content
The purpose of this utility model is a kind of automatic blackboard eraser suction of design box, both can wipe chalk writing and does not produce the blackboard eraser suction box of dust, also can wipe the aqueous ink writing and can keep the blackboard eraser suction box of the long-term cleaning of blackboard eraser.
The technical solution of the utility model: automatic blackboard eraser suction box of the present utility model comprises fluid reservoir and imbibition groove, its fluid reservoir and imbibition groove are arranged side by side, adjacent surface is shared between fluid reservoir and the imbibition slot shell, fluid reservoir is a closed structure, having only with the bottom of imbibition groove adjacent surface has outage to communicate with the imbibition groove, and the blackboard eraser opening is arranged at imbibition groove top; The height of outage is between 5-10mm.
Described automatic blackboard eraser suction box, fluid reservoir top is established the blackboard eraser scrubbing and is squeezed filter pocket, squeeze filter pocket top the blackboard eraser opening is arranged, squeeze in the filter pocket filter grid is housed, squeeze the filter pocket bottom filth storage can is arranged, squeeze between filter pocket and the filth storage can and is communicated with by leading dirty mouthful, filth storage can and fluid reservoir employing parallel construction, the centre separates with dividing plate.
Described automatic blackboard eraser suction box, outage adopts semicircle, and bore dia is between 10-20mm.
Described automatic blackboard eraser suction box has the protruding arrangement of imbibition in imbibition groove bottom, and the protruding height of imbibition is lower than the height of outage.
Described automatic blackboard eraser suction box, filter grid adopts parallel list structure arranged side by side or mesh structural porous structure.
Advantage of the present utility model: the utility model has solved the problem of blackboard eraser appropriateness suction rationally, simultaneously, the waste liquid that accumulates in the blackboard eraser can easily be extruded, and keeps blackboard eraser to clean for a long time, and is convenient and practical.Particularly utilize the atmospheric pressure principle, the elevation of water that makes the liquid storage of fluid reservoir partly enter the imbibition groove is restricted by the height of intercommunicating pore, has both guaranteed the more water of fluid reservoir deposit, has guaranteed the stability of elevation of water of the water of imbibition groove again.
Description of drawings
Fig. 1 is vertical sectional structure schematic diagram of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
As Fig. 1 Fig. 2, Fig. 3, the utility model blackboard eraser suction box is achieved in that
The utility model comprises fluid reservoir 1 and imbibition groove 2, fluid reservoir 1 is arranged side by side with imbibition groove 2, and adjacent surface is shared between fluid reservoir 1 and imbibition groove 2 housings, and fluid reservoir 1 is a closed structure, have only the bottom of adjacent surface 1.2 to have outage 3 to communicate with imbibition groove 2, blackboard eraser opening 2.1 is arranged at imbibition groove 2 tops; The height of outage 3 is between 5-10mm.Outage 3 adopts semicircle, and bore dia is between 10-20mm.
Have imbibition protruding 4 to arrange in imbibition groove bottom, the height of imbibition protruding 4 is lower than the height of outage.Filter grid 6 adopts parallel list structure arranged side by side or mesh structural porous structure.
Using method: clear water (or liniment) has blackboard eraser opening 2.1 to inject imbibition groove 2 by imbibition groove 2 tops, and the automatic blackboard eraser suction box that tilts makes clear water (or liniment) fill with fluid reservoir 1 by outage 3.
Automatic blackboard eraser suction box is upright, and clear water (or liniment) flows into imbibition groove 2 by outage 3, and the height of 2 li liquid of imbibition groove is kept and outage 3 upper end basically identicals.
Blackboard eraser is placed in the imbibition protruding 4 in the imbibition groove 2, wipe with the have gentle hands pressing plate, board wiper plane is contacted with liquid, behind the imbitition, blackboard eraser can be wiped the writing on the board of education.
If the blackboard eraser imbitition is too much or blackboard eraser in the waste liquid of accumulation too much, blackboard eraser is placed on the filter grid 6 in the lautertuns 5, push blackboard eraser with suitable strength, make the liquid of accumulation in the blackboard eraser extrude the back by leading dirty mouthful 8 inflow filth storage cans 7.
After the waste liquid storage of filth storage can 7 was full, with the whole handstand of board wiper box, waste liquid can all be discharged by blackboard eraser opening 5.1.
