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 [0001] The invention relates to a blackboard eraser. Background technique [0002] The blackboard eraser is a common tool in our daily life, which is used to wipe the chalk on the blackboard. Yet the blackboard eraser on the existing market is divided into two kinds, and a kind of adopts the harder bristles of texture, though it is more convenient to clean up, can make chalk dust fly all over the sky when using, and another kind of adopts softer bristles of texture. Hair, although it can effectively solve the problem of chalk dust flying all over the sky, but chalk dust sticks to the soft hair, it is very inconvenient to clean up, thus affecting the use effect. , If you accidentally touch the blackboard, it will make a harsh sound, which is very uncomfortable. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a blackboard eraser, which can effectively prevent chalk dust from flying all over ...
