Abstract
The invention discloses a blackboard eraser which comprises a shell. The shell is made of plastic materials and is of a cuboid structure. The periphery of the front face of the shell is provided with soft furs, the center of the front face of the shell is provided with evenly arranged hard furs, the soft furs are felt, and the hard furs are palm fibres, the soft furs are higher than the hard furs, a magnet is arranged on the back face of the shell, fingerstalls are arranged on the side faces of the shell and made of plastic materials, and openings of the fingerstalls face the back face of the shell. According to the blackboard eraser, chalk characters on a blackboard are wiped off through the hard furs, chalk dust caused by the hard furs is stopped by the soft furs on the periphery, and therefore the phenomenon that the chalk dust flies everywhere when the blackboard is wiped is avoided. The chalk dust falling in hard fur holes can be patted out by only patting the blackboard eraser of the structure slightly, the blackboard eraser is very convenient to clean, and the wiping effect cannot be affected. In addition, the fingerstalls are arranged on the side faces of the shell, and therefore the situation that in the wiping process, fingernails of a wiping person scratch the blackboard carelessly to make a harsh sound is effectively avoided.
Description
Technical field
The present invention relates to a kind of blackboard eraser.
Background technology
Blackboard eraser is a kind of instrument comparatively common in our daily life, and it is for the letter written with chalk on blackboard wiping.Yet, blackboard eraser on existing market is divided into two kinds, a kind of harder bristle of quality that adopts, although its cleaning more for convenience, but use, can make chalk dust fly upward over the sky, the another kind of softer fur of quality that adopts, although it can effectively solve the problem that chalk dust flies upward over the sky, chalk dust is bonded on fur, it is very inconvenient to clear up, thereby affect result of use, in addition, wiping personnel are using blackboard eraser to carry out in the process of wiping, if nail is long, accidentally encounter blackboard, can send ear-piercing sound, extremely feel bad.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of blackboard eraser is provided, it can effectively avoid chalk dust to fly upward over the sky, has the feature easily of clearing up, and can avoid wiping personnel nail the jangle problem of sound of blackboard of swiping.
The object of the invention is to be achieved through the following technical solutions:
A blackboard eraser, comprises housing, and described housing is made by plastic material, for rectangular structure, the periphery in housing front is provided with fur, and its positive core arranges evenly distributed bristle, and described fur is felt, described bristle is palm fiber, the height of described fur is greater than the height of bristle, and the back side of described housing is provided with magnet, and the side of housing is provided with fingerstall, described fingerstall is made by plastic material, and its opening is towards the back side of housing.
As preferred version of the present invention, the side of described housing is connected with expansion link, is convenient to the highly higher blackboard of wiping.
As preferred version of the present invention, the height of described fur is 2cm, and the height of described bristle is 1.7cm.
Beneficial effect of the present invention is, described wiping blackboard structure is simple, be easy to realize, it is in wiping process, by bristle, the letter written with chalk on blackboard is wiped out, and the chalk dust of being done by bristle, fur by surrounding stops, part is bonded on fur, part falls in bristle hole, thereby the phenomenon that while having stopped blackboard wiping, chalk dust flies upward over the sky, and the blackboard eraser of this kind of structure, only need one to clap gently, can take the chalk dust dropping in bristle hole, clear up very convenient, do not affect wiping effect, in addition, by fingerstall being set in housing side, during wiping, wiping personnel's finger can stretch in fingerstall, effectively preventing that the nail of wiping personnel in wiping process is careless swipes and sends ear-piercing sound with blackboard.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of blackboard eraser of the present invention;
Fig. 2 is that a kind of blackboard eraser shown in Fig. 1 is in the cross-sectional schematic at A-A place.
In figure:
1, housing; 2, fur; 3, fingerstall; 4, magnet; 5, bristle.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.Be understandable that, embodiment described herein is only for explaining the present invention, but not limitation of the invention.
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of blackboard eraser of the present invention; Fig. 2 is that a kind of blackboard eraser shown in Fig. 1 is in the cross-sectional schematic at A-A place.
In the present embodiment, a kind of blackboard eraser, comprise housing 1, described housing 1 is made by plastic material, for rectangular structure, the periphery in housing 1 front is provided with fur 2, its positive core arranges evenly distributed bristle 5, described fur 2 is felt, described bristle 5 is palm fiber, the height of described fur 2 is 2cm, the height of described bristle 5 is 1.7cm, the height of fur 2 is greater than the height of bristle 5, the back side of described housing 1 is provided with magnet 4, in the time of no, blackboard eraser can be adsorbed on blackboard, one side side of housing 1 is provided with a fingerstall 3, the opposite side side of housing is provided with three fingerstall 3, described fingerstall 3 is made by plastic material, its opening is towards the back side of housing 1, on housing 1, be connected with expansion link (not illustrating in figure), be convenient to the highly higher blackboard of wiping personnel wiping.
When the present invention uses, by bristle 5, the letter written with chalk on blackboard is wiped out, and the chalk dust being got up by bristle Lane 5, fur 2 by surrounding stops, part is bonded on fur 2, part falls in bristle hole, thereby the phenomenon that while having stopped blackboard wiping, chalk dust flies upward over the sky, and the blackboard eraser of this kind of structure, only need one to clap gently, can take the chalk dust dropping in bristle hole, clear up very convenient, do not affect wiping effect, in addition, by fingerstall 3 being set in housing 1 side, during wiping, wiping personnel's finger can stretch into the interior rear grasping blackboard eraser of fingerstall 3, effectively preventing that the nail of wiping personnel in wiping process is careless swipes and sends ear-piercing sound with blackboard, and housing 1, fingerstall 3 adopts plastic material, avoid housing 1, fingerstall 3 sends ear-piercing sound with blackboard scraping.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
