Compared with the prior art, the remote-controlled electric blackboard eraser of the utility model has the characteristics of reasonable design, simple structure, easy manufacturing, convenient use, good dust-removing effect, etc. Therefore, the utility model has a very good popularizing use-value.
Description
1, technical field
The utility model relates to a kind of teaching equipment, specifically a kind of remote control electric blackboard eraser.
2, technical background
As everyone knows, chalk is by lime stone, gypsum and necessarily than binding agent make and to produce, chalk can become dust at the word that writes out on the blackboard and be dispersed in the air after the blackboard eraser wiping, the chalk dust that floats is because granularity is little, forming aerosol at air suspends in air for a long time to environment generation pollution, these are suspended in airborne chalk powder dust once by in the academics and students's inspiration lung in the classroom, just suffer from various breathing problems easily, as tuberculosis, pulmonary tuberculosis, asthma, rhinitis, can cause lung cancer when serious, have a strong impact on the healthy of teachers and students.In existing technology, use blackboard, chalk and blackboard eraser effect teaching equipment not to overcome all the time manually to erase the board and overcome the pollution of back chalk dust that erase the board environment.
3, summary of the invention
When providing a kind of erasing the board, the purpose of this utility model do not make dust disorderly fly teaching environment is provided the remote control electric blackboard eraser of protection.
The purpose of this utility model realizes in the following manner, be provided with between the bottom on the blackboard, following two channled rails, the two ends of blackboard eraser are provided with the blackboard eraser running gear, the person's handwriting wiping surface of blackboard eraser and the writing surface of blackboard join, sprayer and dust catcher and blackboard eraser running gear controller are set at the back side of blackboard eraser, on blackboard eraser, have the fog spray orifice and dust sucking-off hole joins by pipeline and atomizer and dust catcher respectively, the effect of atomizer is the humidity that increases dust, prevent dust to diffusion all around, the effect of dust catcher is that the chalk dust under blackboard eraser is wiped in time absorbs dedusting.The effect of far infrared control device is the work of control blackboard eraser running gear, atomizer and dust catcher.
Accompanying drawing 2 is that the A-A of remote control electric blackboard eraser is to the section structure schematic diagram;
Accompanying drawing 3 is that the A-A of remote control electric blackboard eraser is to section partial structurtes schematic diagram.
4, description of drawings
Explain below with reference to Figure of description remote control electric blackboard eraser of the present utility model being done.
Remote control electric blackboard eraser of the present utility model, shown in accompanying drawing 1,2, its structure is by upper and lower channled rail 8,1, blackboard eraser 7, blackboard eraser walking mechanism, far infrared control device 16 and dust cancellation element constitute, the two ends up and down that the blackboard eraser running gear is arranged on blackboard eraser 7 join with the upper and lower channled rail 8,1 that is arranged on blackboard both sides about in the of 14 respectively, far infrared control device 16 and dust cancellation element are arranged on the back side of blackboard eraser 7, and the wiping body in blackboard eraser 7 fronts contacts with the writing surface of blackboard 14.
As shown in Figure 2, the blackboard eraser running gear is made up of walker 18, reducing motor 5, gear 3, tooth bar 2, horizontal roller 4 and vertical wheel 17, reducing motor 5 is arranged on the top of walker 18, the axle head of reducing motor 5 is provided with gear 3, gear 3 is meshed with tooth bar 2 on being arranged on channled rail 8,1 up and down and drives blackboard eraser 7 move left and right, and horizontal roller 4 and vertical wheel 17 are joined from horizontal direction and vertical direction and channled rail 8,1 and cooperated with tooth bar 2 the walker location of walking.
The dust cancellation element is made up of sprayer 9 and dust catcher 6, sprayer 9 is arranged on the upper end of blackboard eraser, dust catcher 6 is arranged on the lower end of blackboard eraser 7, and sprayer 9 and dust catcher 6 are respectively by pipeline 11,10 and be arranged on spray holes 13 on the blackboard eraser 7 and air suction opening 12 joins with wiping body on the blackboard eraser 7.
5, embodiment
Its processing and fabricating of remote control electric blackboard eraser of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Blackboard eraser can be made with aluminium section bar and felt, hairbrush or cloth.Walker, channled rail can be processed with aluminium section bar.Far infrared control device, dust catcher, sprayer, reducing motor, level and vertical wheel are general dynamo-electric accessory.
Remote control electric blackboard eraser of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, little, easy to use, the good dedusting effect of volume, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
