Abstract
The invention relates to an electric self-cleaning teaching blackboard. The electric self-cleaning teaching blackboard comprises a blackboard body, wherein a border surrounding the edge of the blackboard body is arranged on the periphery of the blackboard body; a plurality of duct absorption holes are formed in one side close to the blackboard body, of the border; a dust absorber is arranged at the lower end of the border; a duct absorption port of the dust absorber is communicated with the interior of the border; a motor and a gearbox are arranged at each side of the border; output shafts of the two motors are both connected with the gearboxes close to the motors; gears are arranged in border bodies at the two sides of the border and close to the two gearboxes; output shafts of the two gearboxes are engaged and linked with the racks respectively; a transversally-placed strip-shaped blackboard brush is arranged on the blackboard body; the two ends of the blackboard brush are fixedly connected with the two racks respectively; the two racks drive the blackboard brush to vertically move; the two motors are connected with a controller through circuits; and an air outlet device is arranged on the border body at the upper end of the border. The electric self-cleaning teaching blackboard disclosed by the invention automatically cleans, automatically absorbs dust, and generates an air curtain to prevent dust diffusion.
Description
Technical field
The present invention relates to teaching aid technical field, particularly the electronic self-erasing type blackboard for education of one.
Background technology
Blackboard conventional in all kinds of teaching is at present of all kinds, in every case mostly there is dust pollution question in writing on the blackboard employing chalk-writing, badly influence the healthy of teachers and students, especially in middle and primary schools, blackboard in classroom and chalk are students, the thing that teacher can touch every day, particularly when wiping board book, the dust of a sheet of white dances in the air all over the sky, everybody has inevitably sucked some chalk dusts, front-seat classmate, teacher, it is more that student on duty inhales, year in and year out, easily to the lung of students in middle and primary schools and teacher, the upper respiratory tract, eyes, skin, the many places organs such as ear work the mischief, also Other diseases can be brought out, contaminated environment.In order to solve dust pollution question and the labour intensity in order to alleviate the frequent blackboard wiping of teacher in teaching process, people have devised the manual or electric blackboard eraser of many energy automatic dust absorptions, these dust absorption blackboard erasers, all on blackboard eraser, install Small-sized suction cleaner additional to reach the object of dust suction, these dust absorption blackboard erasers, because of the reason of its structure, not only pick-up performance is unsatisfactory, and wiping is rather wasted time and energy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly automatically carries out wiping, automatically receives dust, produces gas curtain and prevent the blackboard for education of dust recycling.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of electronic self-erasing type blackboard for education, comprise blackboard body, described blackboard body periphery is provided with the frame around its edge, described frame is hollow form, described frame is provided with multiple air suction opening near the side of described blackboard body, the lower end of described frame is provided with dust catcher, the suction port of described dust catcher is communicated with described frame inside, described frame both sides are provided with motor and gear-box, two described gear-boxes are in the lower end of two described motors respectively, the gear-box that the output shaft of two described motors is all close with it is connected, being provided with in described frame and close two side frame bodies of two described gear-boxes can the tooth bar of vertical movement, the meshing interlock of tooth bar that the output shaft of two described gear-boxes is close with it respectively, described blackboard body is provided with the strip blackboard brush laterally placed, the two ends of described blackboard brush are fixedly connected with two described tooth bars respectively, blackboard brush vertically movement described in two described rack drives, two described motors have controller by connection, and described frame upper end framework is provided with exhaust apparatus, and described exhaust apparatus is provided with air outlet near the side of described blackboard body.
The invention has the beneficial effects as follows: dust catcher is communicated with described scuncheon, carry out by multiple air suction opening the dust adsorbing chalk; The output shaft that controller controls two motors simultaneously rotates forward, move on two motors are vertical by gearbox speed reduction band carry-over bar, controller controls the output shaft reversion of two motors simultaneously, two motors are vertically moved down by gearbox speed reduction band carry-over bar, tooth bar move on vertically with vertical folding process in all drive blackboard brush carry out on move and move down the wiping realized blackboard body, realize automatically automatically carrying out blackboard wiping; Exhaust apparatus, to canyon, produces gas curtain, can effectively carry out gas curtain close producing chalk dust in blackboard brush blackboard wiping body process, prevents chalk dust to extend influence the health of academics and students.
On the basis of technique scheme, the present invention can also do following improvement.
Further, two described motors be output shaft can the threephase asynchronous of rotating.
The beneficial effect of above-mentioned further scheme is adopted to be: threephase asynchronous technology maturation, Stability Analysis of Structures, effectively can extend the service life of this device.
Further, described controller is provided with can controls rotating forward button that two described motors carry out rotating and reverse and invert button respectively.
The beneficial effect of above-mentioned further scheme is adopted to be: to rotate forward button and invert button is convenient to control motor, lifting operation convenience.
Further, described exhaust apparatus is 10.8 ~ 13.8m by its air outlet blowout wind speed.
The beneficial effect of above-mentioned further scheme is adopted to be: the wind speed of 10.8 ~ 13.8m can produce stablizes gas curtain, prevents chalk dust from spreading.
