The electric dust collection blackboard has simple structure, convenient use, time-saving and labor-saving properties, sanitation and environmental protection, and can effectively collect chalk dust, clean the environment of a classroom, protect the physical health of teachers and students and improve the learning efficiency.

Description

The electric dust absorption blackboard
(1) technical field
The utility model relates to a kind of blackboard, particularly a kind of electric dust absorption blackboard.
(2) background technology
The blackboard that existing school is used to impart knowledge to students, generally adopt traditional mode that blackboard is fixing on the wall, placed apart and the use of blackboard and blackboard eraser, erase the board is to adopt manual type that chalk writing is wiped, not only waste time and energy, labour intensity is big, and can cause chalk dust to fly upward everywhere, produce dust pollution, Faculty and Students healthy brought harmful effect.
(3) summary of the invention
The utility model provides a kind of and has reduced labor intensity in order to remedy the deficiencies in the prior art, avoids the electric dust absorption blackboard of dust from flying.
The utility model is achieved by the following technical solution:
A kind of electric dust absorption blackboard, comprise blackboard body, its special character is: the upper and lower edge of described blackboard body all is equipped with slide rail, and the pulley that is connected with the blackboard eraser two ends is installed in the slide rail, blackboard eraser is made of hairbrush, brush plate, dust catcher and dust box successively, and blackboard eraser connects power switch.
Blackboard eraser is controlled by power supply, and drive pulley is moved on slide rail, and the hairbrush of blackboard eraser cleans the writing on blackboard surface, and the chalk dust of wiping is collected into the dust box under the effect of dust catcher on the blackboard eraser, prevents that dust from scattering, and effectively removes and pollutes.
Fix a silencer on the blackboard eraser described in the utility model.For the prevention blackboard eraser in running because of friction or electronic generation noise, destroy the academic environment in the classroom, on blackboard eraser, fix a silencer.
The lower edge slide rail of blackboard body described in the utility model is provided with fixedly screens.For preventing to drive the pulley placement instability of blackboard eraser motion, on slide rail, slidably reciprocate, influence teaching process, on the slide rail of the lower edge of blackboard body, fixedly screens is set, be used for fixing not driven pulley, with the operation of restriction blackboard eraser.
The utility model is simple in structure, and is easy to use, time saving and energy saving, and hygienic environment-protecting effectively absorbs chalk dust, the cleaning classroom environment, and the protection teachers and students are healthy, improve learning efficiency.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model blackboard eraser.
Among the figure, 1 blackboard body, 2 slide rails, 3 blackboard erasers, 4 pulleys, 5 hairbrush, 6 brush plates, 7 dust catchers, 8 dust boxes, 9 power switches, 10 silencers, 11 fixedly screens.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises blackboard body 1, described blackboard body 1 upper and lower edge all is equipped with slide rail 2, the pulley 4 that is connected with blackboard eraser 3 two ends is installed in the slide rail 2, and blackboard eraser 3 is made of hairbrush 5, brush plate 6, dust catcher 7 and dust box 8 successively, and blackboard eraser 3 connects power switch 9; Fix a silencer 10 on the described blackboard eraser 3; The lower edge slide rail 2 of described blackboard body 1 is provided with fixedly screens 11.
When needs cleaning blackboard, power-on switch 9, drive pulley 4 is moved along slide rail 2, the hairbrush 5 of blackboard eraser 3 is wiped the chalk writing on blackboard body 1 surface, wipe the chalk dust that falls and be collected into dust box 8, it can not be scattered, be connected with silencer 10 on the blackboard eraser 3 by the dust catcher 7 in the blackboard eraser 3, eliminate the noise of its generation, keep good classroom environment.
After cleaning off a blackboard, powered-down switch 9 moves to an end of blackboard body 1 with blackboard eraser 3, by fixedly screens 11 is fixing with pulley 4, prevents that blackboard eraser 3 from moving around on slide rail.
