Abstract
The utility model relates to a blackboard with a blackboard automatically-erasing device, and can eliminate the dust produced in the process of erasing the blackboard. The blackboard automatically-erasing and dust-collecting device is a vertical linearity mechanism that can cover the height of the blackboard; the internal blackboard surface of the mechanism is provided with a plurality of electric operated revolving erasers which are arranged along the vertical direction; the top of the mechanism is a supporting traveling gear and a control circuit; the bottom is a dust-collecting and dust removal equipment. The utility model can erase automatically the handwriting on the blackboard, and can collect the chalk dust, prevent the dust from flying upwards, reduce the environmental pollution in the classroom, and protect the physical and moral integrity of teachers and students.
Description
The utility model is a kind of blackboard that automatic blackboard cleaning device is housed, and can eliminate the dust that produces in the process of erasing the board, and is adapted at carrying out using in the various classrooms of writing on the blackboard with chalk.
At present, still use chalk to carry out writing on the blackboard in most teaching processes, erase the board, can produce a large amount of dust in the process that erases the board, teachers and students' especially teacher healthy and instrument is neatly caused damage with traditional blackboard eraser.Though someone has designed dust-free chalk and dust-sucking eraser, effect is all undesirable, can't satisfy the demand of modern society.
The purpose of this utility model is exactly to design a kind of blackboard with automatic blackboard cleaning and dust arrester, can wipe the writing on the blackboard automatically, can also collect chalk dust, prevents dust from flying, for creating good teaching environment in the classroom.
The utility model is achieved in that whole device is made up of the Glass blackboard of tape frame and automatic blackboard cleaning and dust arrester, automatic blackboard cleaning and dust arrester are a vertical bar shape mechanism that covers the blackboard height, in-house blackboard surface has along vertically disposed several electronic rotation blackboard erasers, the mechanism top is for supporting running gear and control circuit, the bottom is the dedusting dust collect plant, the lower edge is as the track of mechanism supports running gear on the framework of Glass blackboard, entire mechanism is buckled in the bar shaped seal closure, the seal closure upper end is an air inlet, the lower end is the gas outlet and joins with dust collect plant, the close dual-side of seal closure and blackboard along on sealing strip is housed.Electronic rotation blackboard eraser is made up of micro-driving motor and centrifugal the wipings head that is contained in motor shaft end, and on motor shaft, wiping is fixed on the connecting rod outer end to centrifugal wipings head with rod hinge connection, and each electronic swivel plate smears spaced hairbrush and felt is brushed two kinds of centrifugal wiping heads.The dust collect plant of bottom is removable dust bag, with the junction of seal closure sealing strip is housed, and dust bag has negative pressure device outward.When erasing the board, mechanism is along blackboard surface transverse movement, and in-house rotation blackboard eraser is wiped chalk writing, and under suction function, air-flow is motion from top to bottom in mechanism, is being with dust to enter dust bag.
The utility model is easy to use, can wipe the writing on the blackboard automatically, can also collect chalk dust, prevents dust from flying, reduces classroom environment and pollutes, protection teachers and students physical and mental health.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the electronic rotation blackboard eraser of the utility model.
Accompanying drawing 3 is a-a cross-sectional view of the utility model automatic blackboard cleaning and dust arrester.The electronic rotation blackboard eraser that only drawn among the figure, all the other omissions are not drawn.
Whole device is made up of the Glass blackboard 2 of tape frame 1 and automatic blackboard cleaning and dust arrester 6, automatic blackboard cleaning and dust arrester are a vertical bar shape mechanism that covers the blackboard height, in-house blackboard 2 surfaces have along vertically disposed several electronic rotation blackboard erasers 11, the mechanism top is for supporting running gear 6 and control circuit, the bottom is dedusting dust collect plant 8, the lower edge is as the track of mechanism supports running gear 6 on the framework 1 of Glass blackboard, entire mechanism is buckled in 5 li of bar shaped seal closures, seal closure 5 upper ends are air inlet, the lower end is the gas outlet and joins with dust collect plant 8, the close dual-side of seal closure 5 and blackboard along on sealing strip 12 is housed, sealing strip 12 usefulness soft rubbers or plastic strip are made.Electronic rotation blackboard eraser is made up of micro-driving motor 11 and the centrifugal wiping head that is contained in motor shaft end, centrifugal wiping head is hinged on 11 in the motor with connecting rod 10, wipe 14,17 and be fixed on connecting rod 10 outer ends, each electronic swivel plate smears spaced hairbrush 17 and felt is brushed 14 two kinds of centrifugal wiping heads; During motor 11 rotations, make wiping 14,17 pairs of blackboards 2 produce certain pressures,, can on connecting rod, increase governor weight piece 16 for increasing centrifugal force so that wipe clean by centrifugal force.The dust collect plant 8 of bottom is removable dust bag 13, with the junction of seal closure 5 sealing strip is housed, and negative pressure device is arranged outside the dust bag 13.The motor fixing plate of wiping with electronic swivel plate in the present embodiment is divided into former and later two gas channels with seal closure 5, passage by blackboard is used for dust is sent into dust bag 13, the passage of back is used to connect negative-pressure pipeline 9,4,3, and doing like this is in order to reduce the noise in the classroom.When erasing the board, press start button 18,19, mechanism is along blackboard surface transverse movement, and in-house rotation blackboard eraser is wiped chalk writing, and under suction function, the air-flow band dust and entered dust bag 13.Can once wipe complete blackboard, it is returned midway.Dust bag 13 can regularly be cleared up.
