Description
Technical field
The present invention relates to the technical field of tutor auxiliary platform equipment, be specially a kind of dust-free black board eraser.
Background technology
Chalk is indispensable writing implement in teaching, acquires attending class of university all use chalk from little.And chalk dust
Pollution problem the most also enjoy people to pay close attention to, therefore had the design of a lot of solution chalk dust.Such as dust-free chalk, dust-proof
Blackboard erasers etc., dust-proof blackboard eraser is usually and encloses dust-proof sponge etc., so certain in the flannelette outer ring of blackboard eraser design one
Chalk dust can be effectively suppressed to kick up in degree.But the dust-proof effect of this blackboard eraser is inconspicuous, and process chalk dust time
Wait and typically also take to knock, be the most also intended to cause certain dust pollution.During at school, the commonly used blackboard eraser of teacher
Erase the board, but the blackboard eraser that school commonly uses now is simply made up of shell and felt, is easy to when erasing the board make
Chalk dust disorderly flies, and have impact on the healthy of teacher and front-seat student.Meanwhile, chalk dust falls on the ground, and student on duty is when cleaning
Very inconvenient.Application No. 2008102036835, the patent of invention of entitled dust-proof blackboard eraser solves the problems referred to above, but
This patent product does not the most solve the secondary pollution of chalk dust, is to be collected completely by chalk ash collection chamber such as it yet
After, to open spiral cover and outwell chalk dust, it also can make chalk dust again kick up during outwelling chalk dust, causes dust dirty
Dye.But it does not solve chalk dust and drops problem on the ground, and 201210403010.0 patents of invention of Application No. solve
The problems referred to above, but still there is dust pollution when outwelling chalk dust in it.
At present, market also has electronic can with Blackboard eraser capable of absorbing dust, but if student is had the biggest by electric wire electric leakage
Harm otherwise cannot play dust-proof effect.Therefore for the problems referred to above, we have developed a kind of simple in construction, are fabricated to
This is low, chalk dust not only will not be made disorderly to fly, nor chalk dust can be made to drop on the ground during erasing the board, dust-proof effect
The best dust-free black board eraser.
Summary of the invention
It is an object of the invention to for above-described problems of the prior art, it is provided that a kind of simple in construction, system
Make low cost, chalk dust not only will not be made during erasing the board disorderly to fly, nor chalk dust can be made to drop on the ground, anti-
The dust-free black board eraser that dirt is effective.
In order to realize described purpose, the present invention specifically adopts the following technical scheme that
A kind of dust-free black board eraser, including blackboard eraser body 1；It is characterized in that: described blackboard eraser body 1 includes that at least two is cotton
Brush roll 2, its cotton wool brush roll 2 is connected with ash storage box body 3 by rotating shaft, and the spacing between two adjacent cotton wool brush rolls 2 is
0.8-1.5cm；Inside described ash storage box body 3, below cotton wool brush roll 2, it is provided with brush body 4, and connecting plate 5 is provided with and plate
Wiping the projection that the guide rail on body 1 inwall connects, connecting plate 5 is provided with driving means, and its drive connection plate 5 regulates brush body
Distance between 4 and cotton wool brush roll 5, makes brush body free end and cotton wool brush roll ensure to be in close contact；Described connection brush
The connecting plate 5 of body 4 is network structure, below connecting plate 5, is provided with dust wetting device 6 inside ash storage box body 3, and outside is provided with
Control switch, and ash storage box body 3, connecting plate 5 define cavity with protective cover 7.
The bristle configurations of described brush body 4 is semicircular structure, and the lower half of cotton wool brush roll 2 is arranged on brush originally
In the semicircular structure of body 4, increase brush body 4 and remove the area of cotton wool brush roll, add the effect removing chalk dust.
Described ash storage box body 3 lateral surface is provided with the first buckle structure 8, and its first buckle structure 8 sets with protective cover 7 side
The second buckle structure 9 put connects.
Described protective cover 7 outside bottom surface is provided with handle 10.
Described handle 10 is connected with protective cover 7 by sucker structure.
Be provided with sealing structure above described ash storage box body 3 and between cotton wool brush roll 2, and the central point of cotton wool brush roll 2 with
The upper edge of ash storage box body 3 is in same level.
The edge, top of described ash storage box body 3 is provided with arc storage ash-pit 11, and cotton wool brush roll 2 is than arc storage ash-pit 11
Upper edge exceeds 0.3-1.2cm.
Described protective cover 7 is provided with chalk and stores cavity.
The free end chondritic of described brush body 4, and brush body 4 is in plastic brushes, stainless steel brush
Kind or the distributing alternately of two kinds of brushes.
The thickness of described connecting plate 5 not can exceed that 0.2cm, and its thickness is the thinnest, and the chalk dust of brush body 4 cleaning more holds
Easily fall in the cavity that ash storage box body 3, connecting plate 5 and protective cover 7 are formed.
One dust-free black board eraser of the present invention, cotton wool brush roll 2 is connected with ash storage box body 3 by rotating shaft, and two adjacent cottons
Spacing between brush roll 2 is 0.8-1.5cm, is provided with brush body 4, ash storage box below ash storage box body 3 inside, cotton wool brush roll 2
Body 3 is internal is provided with dust wetting device 6；During use, operator holds handle 10, applies an external force to blackboard eraser body, makes
Cotton wool brush roll 2 rotates around the shaft, simultaneously blackboard wiping, revolves owing to cotton wool brush roll 2 does around the shaft during blackboard wiping
Transhipment is dynamic, therefore the side of the cotton wool brush roll of wiping blackboard can then rotate in brush body 4, then cotton wool brush roll 2 and brush
Sub-body does fricting movement, is i.e. brushed off by the chalk dust on cotton wool brush roll 2 by brush body 4, and it is easy to operate, black in wiping
Just being cleaned out by the chalk dust on cotton wool brush roll 2 during plate, the blackboard causing cotton wool brush roll 2 wiping is the cleanest.
Compared with prior art, the beneficial effects of the present invention is: one, cotton wool brush roll 2 is by rotating shaft with ash storage box body 3 even
Connecing, and the spacing between two adjacent cotton wool brush rolls 2 is 0.8-1.5cm, it is during blackboard wiping, facilitates chalk dust to fall
Enter in ash storage box body 3；Two, described ash storage box body 3 is internal, be provided with brush body 4 below cotton wool brush roll 2, and brush body 4
Free end is in close contact with cotton wool brush roll 2, and it makes cotton wool brush roll 2 and brush body 4 do fricting movement, and i.e. brush body 4 is by cotton
Chalk dust in brush roll 2 is cleaned out all the time, and the blackboard surface making cotton wool brush roll 2 wiping is very clean, solves in prior art
Blackboard eraser body can not be cleared up because of long-time blackboard wiping, the chalk dust of accumulation, and causes the blackboard of blackboard eraser body wiping not totally,
The problem that even can not carry out again writing；Three, below connecting plate 5, inside ash storage box body 3, it is provided with dust wetting device 6, works as chalk
After ash falls into ash storage box body 3 inside, open control switch, make dust wetting device 6 that dry chalk dust to be drenched, in storage
When chalk dust in ash casing 3 stores full, chalk dust moistening during pouring out will not be at airborne dust and pollution environment；Four, institute
Protective cover 7 outside bottom surface stated is provided with handle 10, facilitates operator to hold with a firm grip blackboard eraser, it is not easy to make blackboard eraser drop；Five, described
The edge, top of ash storage box body 3 is provided with arc storage ash-pit 11, and arc stores up the upper edge of ash-pit 11 and the peak of cotton wool brush roll 2
On the same water surface, chalk dust will not be made to drop on the ground, good dustproof effect.
