Description
Technical field
The present invention relates to educational aid field, more particularly to a kind of blackboard eraser for preventing that chalk dust from flying upward.
Background technology
Blackboard is most important instrument in present education and instruction, although currently there is the emerging religion such as various display screens, projection
Equipment is learned, but blackboard can not be substituted its status as widest instrument.Current blackboard have Glass blackboard, cement blackboard,
Wooden blackboard, high molecular polymerization blackboard etc., it can all produce substantial amounts of chalk dust when erasing the board.One student acquires from small
Finish college about 16 years, this is also exactly the gold period of growth, and dust pollution has had a strong impact on the development health of student.
One teacher's slave station was about 40 years to dais to retirement, and dust pollution is even more the physical and mental health for having had a strong impact on teacher.
Although the current blackboard for also having various anti-dust, most effect is bad, it is complicated, in-convenience in use unfavorable
In popularization.Because the diversity and its quantity of blackboard are larger, if just transformed blackboard, it is not intended to many costs can be increased, no
Utilize utilization and extention.
The content of the invention
The problem of being flown upward present invention aim to address chalk dust during the letter written with chalk on current blackboard wiping, there is provided Yi Zhongfang
The blackboard eraser that only chalk dust is flown upward, allow its be used in various unlike materials, structure blackboard on.
The technical solution adopted by the present invention is：A kind of blackboard eraser for preventing that chalk dust from flying upward, including box body, in the box body
Provided with inner chamber, battery, electrostatic generator and rotary shaft are provided with the inner chamber, support bar is provided between the rotary shaft, it is described
The outside of rotary shaft and support bar is socketed wiper, and the support bar is connected with elastomeric pad, the elasticity towards box body outside portion
Pad is between support bar and wiper；The electrostatic generator electrically connects support bar, and the battery electrically connects electrostatic generator
And rotary shaft；The wiper is made for conductive material.
As a further improvement on the present invention, dividing plate is additionally provided with the inner chamber, the dividing plate is located above wiper, one end
It is connected with box body, the other end is in close contact with wiper.
As a further improvement on the present invention, button, the work of the button control electrostatic generator are also included.
As the further improvement of the present invention, the surface of the wiper is provided with fine, soft fur brush.
As the further improvement of the present invention, the box body is provided with the dodge gate for removing chalk dust in box body.
The beneficial effect that the present invention uses is：The blackboard eraser of this structure, attract the physics of molecule special using electrical body
Property is made.Suitable for diversiform blackboard eraser, popularization is utilized.Simple in construction, easy to use, environment-friendly high-efficiency of the invention.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is top view of the present invention.
Shown in figure：1 box body, 2 rotary shafts, 3 support bars, 4 wipers, 5 elastomeric pads, 6 buttons, 7 electrostatic occur
Device, 8 batteries, 9 dividing plates.
Embodiment
With reference to Fig. 1 and Fig. 2, the present invention is described further.
As illustrated, a kind of blackboard eraser for preventing that chalk dust from flying upward, including box body 1, the box body 1 is interior to be provided with inner chamber, institute
State and battery 8, electrostatic generator 7 and rotary shaft 2 are provided with inner chamber, support bar 3, the rotary shaft 2 are provided between the rotary shaft 2
Wiper 4 is socketed with the outside of support bar 3, the support bar 3 is connected with elastomeric pad 5, the cushion towards the outside portion of box body 1
Piece 5 is between support bar 3 and wiper 4；The electrostatic generator electrically connects support bar 3, and the battery electrically connects electrostatic
Device 7 and rotary shaft 2；The wiper 4 is made for conductive material.
The one side that wiper is located at working end by elastomeric pad ejects, the wiping that Convenient blackboard is wiped.
In order to prevent chalk dust from entering in electrostatic generator and battery, so as to influence work, dividing plate 9 is additionally provided with, it is described
Dividing plate 9 is located at the top of wiper 4, and one end is connected with box body 1, and the other end is in close contact with wiper 4.Dividing plate is by the powder on wiper
Pen ash completely stops, and its whole is deposited in the rear portion of box body.Dividing plate separates electrostatic generator and battery with chalk dust
Come.
In order to further improve the comfort of the present invention and use for a long time, also include button 6, the button 6
Control the work of electrostatic generator 7.When button is pressed, electrostatic generator is started working so that it is guaranteed that wiper is powered.
Letter written with chalk on blackboard can be effectively removed in order to improve the blackboard eraser of the present invention, the surface of the wiper 4 is provided with
Fine, soft fur brush.
In order to efficiently and effectively remove the chalk dust in box body, the box body 1, which is provided with, removes chalk dust in box body
Dodge gate.
The present invention works as follows：
When needing to use blackboard eraser blackboard wiping, start electrostatic generator, so that it is guaranteed that the wiper of blackboard eraser is powered.Profit
With wipe blackboard, chalk dust can be firmly adsorbed on wiper, after wiping, rotary shaft rotates, so that will
It is moved to one end that chalk dust is carried on wiper in box body.Now electrostatic generator powers off, and chalk dust falls within blackboard eraser
In powder.When using this blackboard eraser, blackboard eraser is inverted best results after wiping.After adding dividing plate, dividing plate in itself can
Prevent the chalk dust on wiper from entering one end that electrostatic generator and battery is distributed with, while can also completely cut off two of box body
Point, prevent to fall into the chalk dust elegant influence work everywhere of box body.
The blackboard eraser of this structure, the physical characteristic for attracting molecule using electrical body are made.Structure letter of the present invention
Single, easy to use, environment-friendly high-efficiency.
The present invention is suitable for various materials, variously-shaped blackboard, so as to save the transformation expense of blackboard, beneficial to popularization.
