Description

Chalk powder sucking chalk powder {chalk powder suction case}

 BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chalk case for primarily sucking chalk powder generated in using chalk.

Chalk is used to write on the chalkboard. However, ordinary chalk is scattered in the process of writing. Of course, to compensate for the above phenomenon, water chalk came out, but in reality, the life of the chalkboard is shortened, and the problem of replacing the chalkboard to use the water chalk is very costly. Therefore, the present invention is to add the present invention to ordinary chalk, thereby relieving the burden on the respiratory patient who is suffering from a health problem when the chalk powder is inhaled, and preventing the air around the chalkboard from becoming cloudy.

In order to solve the above problem, the chalk powder generated from the chalk is first sucked to prevent the chalk powder from being blown.

Put the inhaler in the front part of the chalk case to suck up the chalk powder that occurs when you make the pancake. The filter will filter the chalk powder in the future. The ON / OFF switch can be used to adjust the operation of the aspirator.

Since chalk powder is first inhaled during writing, it is possible to minimize the damage to people with respiratory diseases. It also prevents the air around the board from becoming cloudy.
