Abstract
The invention relates to a blackboard eraser allowing cyclic utilization and belongs to the technical field of blackboard eraser structures. The blackboard eraser allowing the cyclic utilization comprises a blackboard eraser main body; wiping cloth is arranged on the front side of the blackboard main body; the interior of the blackboard eraser main body is hollow; a mini-sized dust absorption fan is arranged in the interior of the blackboard eraser main body; dust absorption holes which are communicated with the interior of the blackboard eraser are formed in the wiping cloth; a chalk reproduction device which is connected with the dust absorption fan is arranged in the interior of the blackboard eraser main body; the left side of the blackboard eraser main body is provided with a battery groove to place batteries; the right side of the blackboard eraser main body is provided with a magnet to enable the blackboard eraser to be absorbed on a magnetic blackboard; the rear portion of the blackboard eraser main body is provided with an indicator and a switch. The blackboard eraser allowing the cyclic utilization can absorb powder to protect human health, can reproduce chalks by utilizing wiped powder, saves resources and provides great convenience for users.
Description
one, technical field
The present invention relates to a kind of blackboard eraser recycled, belong to the wiping blackboard structure technical field.
two, background technology
For a long time, blackboard, always as the necessary supply of classroom instruction, supplies teacher and student writing and teaching data.But the blackboard area is limited, need be with the continuous wiping of blackboard eraser to write new content, during wiping, chalk dust dances in the air all over the sky, not only affects teacher's dressing, and lives in the chalk dust after blackboard wiping throughout the year, easily causes nose, pharynx, throat's discomfort.
three, summary of the invention
The object of the invention is to solve the weak point that above-mentioned prior art exists, a kind of blackboard eraser that recycles that a kind of structure is simple and direct, reasonable in design, economize on resources is provided.
A kind of blackboard eraser recycled of the present invention, comprise blackboard eraser main body 1, blackboard eraser main body front is provided with wiper 2, and its special character is that the blackboard eraser body interior is hollow, its inside is equipped with small duster blower fan 3, is provided with the air suction opening 4 be connected with blackboard eraser inside on wiper;
The described blackboard eraser recycled, its inside is equipped with the chalk be connected with dust absorption fan and reproduces device 5, and the powder of absorption all is stored in this equipment, to prepare new chalk;
The described blackboard eraser recycled, its left side is provided with battery case 6 to lay battery, and right side is provided with magnet 7 so that blackboard eraser is adsorbed on magnet board;
The described blackboard eraser recycled, its back is provided with indicator lamp 8 and switch 9.
A kind of blackboard eraser recycled of the present invention, not only can absorb powder, and the protection health, can utilize again the powder reconstructed chalk after wiping, economizes on resources, and to the user, brings very big facility.
four, accompanying drawing explanation
Fig. 1: the present invention recycles the structural representation of blackboard eraser;
Fig. 2: blackboard main body structure schematic diagram;
Fig. 3: blackboard body interior structural representation;
In figure: 1: the blackboard eraser main body; 2: wiper; 3: dust absorption fan; 4: air suction opening; 5: chalk reproduces device; 6: battery case; 7: magnet; 8: indicator lamp; 9: switch.
five, the specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present invention, be used for formation of the present invention is further described.
A kind of blackboard eraser recycled, comprise blackboard eraser main body 1, and blackboard eraser main body front is provided with wiper 2, and the blackboard eraser body interior is hollow, and its inside is equipped with small duster blower fan 3, is provided with the air suction opening 4 be connected with blackboard eraser inside on wiper; Its inside is equipped with the chalk be connected with dust absorption fan and reproduces device 5, and the powder of absorption all is stored in this equipment, to prepare new chalk; Its left side is provided with battery case 6 to lay battery, and right side is provided with magnet 7 so that blackboard eraser is adsorbed on magnet board; Its back is provided with indicator lamp 8 and switch 9.
During blackboard wiping, open switch, indicator lamp is bright, and the small duster blower fan absorbs the connected chalk reforging equipment of dust absorption fan by air suction opening by powder, and while storing enough powder, equipment manufactures chalk by powder; During the complete blackboard of wiping, closing switch, be adsorbed on blackboard eraser on magnet board.
A kind of blackboard eraser recycled of the present invention, not only can absorb powder, and the protection health, can utilize again the powder reconstructed chalk after wiping, economizes on resources, and to the user, brings very big facility.
