Description
Technical field
The utility model is related to educational outfit technical field, more particularly to a kind of English teaching board.
Background technology
Blackboard and blackboard eraser are indispensable teaching aids in classroom teaching, and Faculty and Students can be with chalk in blackboard
Upper arbitrarily writing, is then wiped, then repeated writing with blackboard eraser.
But many dust can be produced when being wiped with blackboard eraser, these dust fly away everywhere in classroom, part meeting
By in Faculty and Students' suction body, their healthy is had a strong impact on.
Therefore electric dustless blackboard eraser arises at the historic moment, and electric dustless blackboard eraser in the market mainly has two kinds.
One kind is electronic dust suction blackboard and supporting blackboard eraser.It is that high pressure dust-absorbing plate is placed in into Glass blackboard or wooden blackboard
Below, with the ordinary blackboard eraser blackboard wiping being made with hairbrush or porous material.Principle be blackboard surface formation high pressure it is quiet
In electric field, dust is attached on blackboard surface, and its charge polarity is in neutrality.When the blackboard eraser that dust is moved has been wiped, its electric charge
Polarity is identical with high pressure dust-absorbing reversal of plate polarity and is ostracised, due to mobile blackboard eraser in the presence of highfield corona polarity with it is high
Dust-catching board opposite polarity is pressed, so the dust wiped is by the polarity repulsion of high pressure dust-absorbing plate to blackboard eraser hairbrush or porous material
It is interior, play a part of dust suction.
Another is ash-collecting blackboard eraser.Principle is to produce air suction using the rotating vane rotation of blackboard eraser bottom,
The dust produced in wiping process is drawn into blackboard eraser intracavitary or dust bag, the effect of dust suction is reached.
But the price of the first scheme is costly, installation cost is too high.Although second scheme relative inexpensiveness
Some, but blackboard eraser therein is similar with the size of ordinary blackboard eraser, needs to carry out repeatedly repeatedly on blackboard surface when using
Wipe, and also need to traction and dust collection pipeline, considerably increase the labor intensity of teacher or student.
Utility model content
The utility model is to overcome above-mentioned deficiency of the prior art to be taught there is provided a kind of dust-collecting type English of fast power-saving
Learn plate.
The utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of English teaching board, including square blackboard and blackboard eraser, the upper and lower side frame of foregoing blackboard provided with its groove to
Slidably connected respectively in the parallel T-shaped chute of upper and lower side frame, T-shaped chute between T-shaped sliding block, T-shaped sliding block and be connected with its axle center
The two piece guide rails parallel with the left and right side frame of blackboard, foregoing blackboard eraser includes the open strip box-like housing in side bottom surface, shell
It is rotatably connected in vivo in roller wiping, housing and is provided with the funnelform wind scooper of flat, the big opening end of wind scooper covers roller wiping, leads
The osculum end of fan housing exposes to housing, and housing is provided with motor, and the output shaft of motor is wiped with roller to be connected, the both sides of housing
Provided with sliding shoe, sliding shoe is slidably connected with guide rail, left and right side of the axle center that the length direction and roller of housing are wiped with blackboard
Frame is parallel, and the radial direction outer of roller wiping and the opened lower surface of housing are attached on blackboard surface.
The osculum end of wind scooper in this programme is used to connect dust collection pipeline, and pick-up performance can be improved by wind scooper.
Whole blackboard surface is almost covered when blackboard eraser is slided and is wiped by T-shaped chute and two guide rails, it is not necessary to during blackboard eraser
Blackboard eraser can be moved on to and be write while not interfering with blackboard surface, this scheme only needs mobile blackboard to wipe, can be with
Greatly save muscle power.And the Design of length for wiping roller into 1/3rd of the height of blackboard arrive overall height when, need to only move back
Dynamic blackboard eraser just almost by whole blackboard surface wiped clean, is wiped very quick two or three times.
As further improved structure type, the lattice chalk scriber of four line three, four are slidably connected on above-mentioned guide rail
Screw is threaded with the lattice chalk scriber of line three, screw is turned and can lock the lattice chalk scriber of four line three and exist
Position on guide rail.The lattice of four line three of writing English, very convenient English religion can also be directly skidded off while being wiped
Learn work.
As further improved structure type, micro-cleaner, the suction of micro-cleaner are connected with above-mentioned housing
Dirt mouthful is sealed with the osculum end of above-mentioned wind scooper and connected, thus need not traction dust collection pipeline, it is not only laborsaving but also do not affect the appearance
Property.
As further improved structure type, the back side uniform intervals of above-mentioned blackboard are disposed with rectangle iron plate, above-mentioned
Housing in be evenly arranged magnetic stripe, this structure can be such that blackboard eraser is brought into close contact in blackboard surface, improve erasing effect.
As further improved structure type, above-mentioned motor is direct current generator, and above-mentioned micro-cleaner is direct current
The battery pack that promising motor and micro-cleaner are powered is connected on driving type suction cleaner, above-mentioned housing.This structure can be saved
Circuit is pulled, further laborsaving and guarantee aesthetic property.
The utility model mainly has the advantages that compared with prior art：Made by T-shaped chute and two guide rails
Blackboard eraser slides and almost covers whole blackboard surface when being wiped, it is not necessary to can be moved on to blackboard eraser while will not during blackboard eraser
Influence is write on blackboard surface, can greatly save muscle power, three points into the height of blackboard of the Design of length that roller is wiped
One of when arriving overall height, it is just almost clean by whole blackboard-cleaning two or three times only to move back and forth blackboard eraser, wipes very quick.
