Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of dust-free blackboard.
Background technology
Blackboard is a kind of the most frequently used teaching equipment.Although having widely used projecting apparatus etc. realizes E-learning now, blackboard writing has irreplaceable effect in vivid teaching.And adopt projecting apparatus to need supporting apparatus such as computer, price is comparatively high, is not too suitable for economically underdeveloped area and promotes the use of.When using blackboard, chalk must be adopted to write, and traditional blackboard, in wiping chalk process, can produce a large amount of dust, has had a strong impact on the healthy of academics and students.And traditional blackboard size, height etc. are fixing, use very inconvenient.Although having had now can the report of blackboard of automatic erasing, due to complex structure, cost is higher, and wiping is clean, is unfavorable for promoting the use of.
Summary of the invention
The purpose of this utility model is just to provide a kind of dust-free blackboard, to solve the problem.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of dust-free blackboard, comprise blackboard body, described blackboard body is flexible body, described blackboard body head and the tail are closed, and described blackboard body is also connected with support, and the two ends of the blackboard body closed from beginning to end are provided with rotating shaft, described blackboard body is shuttling movement with the rotation of described rotating shaft, and described rotating shaft is connected with the first motor; Also comprise blackboard frame, described blackboard body is removably connected by described support and described blackboard frame; Also comprise at least two brush bars, described brush bar is positioned at after described blackboard body, and the two ends of described brush bar connect with the inner side of the right and left of described blackboard frame, gap is left between described brush bar and described blackboard body, and, described brush bar is connected with telescoping mechanism, and described telescoping mechanism connects the second motor; The side of described blackboard frame is provided with control button, and described control button connects to described first motor and/or the second motor and arranges corresponding control program.
Blackboard body of the present utility model forms the structure being similar to conveyer belt by rotating shaft, by controlling rotating shaft, realizing the circulating rolling of blackboard body, thus making whole blackboard body may be used to write; Support is set, conveniently writes on the one hand, removably connect with blackboard frame on the other hand, maintain easily and clear up the dust inside blackboard frame; When needs blackboard wiping, second driven by motor telescoping mechanism, thus brush bar is contacted with blackboard body, make blackboard move up and/or down simultaneously, realize the wiping of blackboard, process due to blackboard wiping is carried out at the back side of blackboard body, meanwhile, blackboard frame and blackboard body form closed space, thus make in the process of wiping, do not have dust to fly away with surrounding before blackboard body, realize the effect of dust-free blackboard.
As preferred technical scheme: described brush bar comprises cloth brush and hairbrush, and described cloth brush and hairbrush spaced apart.Wiping effect can be made better, and wiping is cleaner.
As preferred technical scheme: described brush bar is obliquely installed.Wiping effect can be made better, and wiping is cleaner.
As preferred technical scheme: described control button is three, be arranged at the left side of described blackboard frame.Handled easily.
As further preferred technical scheme: described three control buttons be followed successively by from top to bottom turn over button, wiping button and under turn over button, turn on described button with under turn over button and be connected with described first motor, described wiping button is connected with the second motor with described first motor simultaneously.During use, if do not need blackboard wiping, only need to stir blackboard up or down, namely can only press button up or down, this is only the first machine operation, and stir when can realize pressing button by program, stop stopping during pressing, thus the convenient position controlling blackboard body; If need to carry out wiping, then press wiping button, at this moment the first motor and the second motor cooperating simultaneously, while stirring blackboard body, makes brush bar contact with blackboard body, realizes wiping function.
As preferred technical scheme: be provided with dust collection groove on the downside of described blackboard frame.Dust after wiping drops to dust collection groove, and the back side of blackboard body can be made cleaner and tidier.
As further preferred technical scheme: described dust collection groove is built-in is placed with water.Dustless effect can be made better.
As further preferred technical scheme: be provided with water inlet and delivery port in described dust collection groove.Facilitate the discharge with sewage of putting into of clear water.
As preferred technical scheme: described brush bar surface is 1-2cm with the gap of blackboard body.Suitable gap can make structure more reliable and more stable.
As preferred technical scheme: be also provided with dust exhaust apparatus in the surrounding of described brush bar.
First after being adsorbed by dust exhaust apparatus by the chalk dust of brush bar wiping, do not dropped to dust collection groove again by the part of adsorbing completely, dustless effect can be made better, reduce the frequency that dust collection groove arranges simultaneously, use more convenient.
Compared with prior art, the utility model has the advantage of: dust-free blackboard of the present utility model can realize the effect of good dust-free cleaning, meanwhile, structure is simple, controls and uses all very convenient, being suitable for promoting the use of.
