Description
Technical field
The utility model belongs to the technical field of teaching appliance, is specifically related to a kind of for the large-scale dustless of magnet board
Blackboard eraser.
Background technology
Blackboard brings many convenience, the blackboard used at present is mostly that magnetic is black as common educational aid for teaching
Plate.But blackboard, there is also some problems, existing blackboard eraser is very compact, it is necessary to up and down compared to for blackboard
Repeatedly wipe, it is quite time-consuming laborious, particularly with small student, it is impossible to touch eminence, bring very big tired to erasing the board
It is difficult.
The least a portion of chalk dust in surface can only be taken away when erasing the board simultaneously, most chalk dust is with the pendulum of blackboard eraser
Dynamic to be scattering into air, the aerial chalk dust that is scattered not only pollutes the environment, and also affects teachers and students' health, causes and one is
The breathing problem of row.Substantial amounts of chalk dust, the shape between blackboard and blackboard eraser can be accumulated after the continuous use of blackboard eraser on surface
Into one kind lubrication, the degree that the difficulty and chalk dust of wiping are scattered is increased, needs to spend larger strength when erasing the board, wipes
The place wiped can also leave white scratch, have impact on the definition of writing next time;Especially when the area of wiping is excessive, blackboard eraser
When the chalk dust of surface attachment can not drain in time, wipe the blackboard do not write and can also leave one piece of block and wipe leave white
Print, and substantial amounts of chalk dust can be scattering into air.These white vestiges and scratch have had a strong impact on the sight of classmate,
Cause all not seeing many times, obstinate written trace error message occurs after even overlapping with the content newly write,
Slow down the teaching process of teacher, aggravate the learning burden of student.
When being write on blackboard, a large amount of chalk dusts are entered in the pit of blackboard, only a small amount of chalk dust attachment
On the surface of blackboard.When erasing the board, blackboard eraser siphons away the chalk dust on blackboard surface, and the powder that can not be acted on inside pit
Pen ash, the surface of blackboard will leave the vestige write and be difficult to wipe clean.
The content of the invention
The purpose of this utility model is to provide a kind of large-scale nothing for magnet board for above-mentioned defect
Dirt blackboard eraser, the blackboard eraser greatly reduce manpower without manually, at the same volume it is large-scale so that an erasing area significantly
Increase, shortens the time of erasing the board;The blackboard eraser has two-stage dedusting, effectively improves the dust removing effects of blackboard eraser, reduces
Pollution of the chalk dust to environment and the injury to human body.

Embodiment
Below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
From figure 1 it appears that a kind of large-scale dust-free black board eraser for magnet board of the present utility model, including frame
1 and the lower section of frame 1 dust exhaust apparatus, dust collect plant and the wiping arrangement that are fixedly connected sequentially;Install successively the upper surface of frame 1
There are single-chip microcomputer 2, electric machine controller 3 and battery 4, pulley 5 is separately installed with the two ends of frame 1, pulley 5 is connected with the He of motor I 6
Travel switch 20, the lower surface of frame 1 is separately installed with magnet 7 at pulley 5;Dust exhaust apparatus includes shell 8, the shell 8
Top be fixed on the lower surface of frame 1, shell 8 is built-in with motor II 9, and motor II 9 connects a fan 10, shell 8 it is outer
Side is provided with air intlet provided with switch 11 and battery case 12, the bottom of shell 8;Dust collect plant includes dust-collecting box 13, dust-collecting box 13
Top be provided with air outlet slit, the air intlet that the air outlet slit passes through airstrainer 14 and dust exhaust apparatus shell 8 is fixed and connected
Connect, the bottom of dust-collecting box 13 is provided with dust import;Wiping arrangement is included on the brush holder 15 with cavity, the top plate 16 of brush holder 15
It is even that bristle 17 is distributed with, dust outlet is provided with the center of the top plate 16 of brush holder 15, the dust outlet passes through dust-filtering net 18
Dust import with the bottom of dust collect plant dust-collecting box 13 is connected, and the opening end outer of brush holder 15 is provided with fixed in groove, groove
There are felt layers 19.
The shell 8 is provided with some heat emission holes.Heat can be produced in motor operation course, therefore sets heat emission hole and is played very well
Ventilation effect.
The inner surface of the shell 8 is wavy provided with polyester fiber acoustical cotton layer, acoustical cotton layer.Can sound insulation again
It can absorb sound, in wavy so that acoustical cotton layer can make motor fully radiate again while abundant sound-absorbing purpose is reached.
The dust-filtering net 18 is using containing flannelette bag.The bag containing flannelette can not only ensure that venting capability is good, additionally it is possible to
By dust inspiration.
The airstrainer 14 is using double-deck sponge.Not only ensure air circulation, pass through while suppressing dust, finally make
Dust is obtained to stay in dust-collecting box.
The blackboard used at present is mostly magnet board, and magnet board can use magnet adsorption to provide positive pressure on surface
Power, the blackboard eraser is exactly that can adsorb on blackboard surface to provide positive pressure using magnet.There is provided using magnet during wiping
Pressure when required normal pressure and pulley operation.Two ends large area magnet is used for providing normal pressure during wheel operation, big face
Long-pending magnet can produce sufficiently large power to ensure the friction between pulley and blackboard surface.
Pulley is distributed in the two ends of frame, and running orbit is exactly blackboard most marginal position, the most marginal position writing of blackboard
Number of times it is few, corresponding cleaning can be kept, it is to avoid pulley skidding caused by chalk dust, provided for pulley with seriticker
One stable route.Pulley, which is arranged on two ends, can also save space required when blackboard eraser is stood, it is therefore prevented that wipe way
In blind area.
Letter written with chalk of the bristle action closely arranged using brush holder top plate above blackboard, once wipes past tense, closely
The bristle chalk dust acted in blackboard surface or pit repeatedly, therefore there is compact arranged bristle stronger cleaning to imitate
Really.Felt layers in the groove of brush holder opening end outer, can form with blackboard surface and preferably contact, the powder that bristle is taken away
Pen ash is enclosed in the cavity inside brush holder, it is therefore prevented that the diffusion of chalk dust, reaches preferable primary dust removing effect.
Dust exhaust apparatus turns on the power rear motor II and drives fan rotation, produces extremely strong suction, makes the inside and outside generation of dust-collecting box
Effective pressure differential, most dust is drawn into storage in dust-collecting box at last, reaches two-stage dust removal.
When pressing electric machine controller START button, blackboard eraser starts to walk to the right, and the scope passed by is wiped clean,
When blackboard eraser travel switch is detected up on the right of blackboard, blackboard eraser auto-returned, then blackboard is cleaned one time;When blackboard eraser row
When Cheng Kaiguan is detected up to the blackboard left side, blackboard eraser stops, and completes a wiping process.
Whole blackboard eraser is controlled using single-chip microcomputer, and travel switch is used for detecting the position where blackboard eraser.
