Description

multi-function eraser

technical field

The utility model relates to a teaching tool, in particular to a multifunctional eraser.

Background technique

The blackboard is one of the most important tools in the teaching process. Although the blackboard has brought great convenience to teaching, there are many shortcomings at the same time, that is, a large amount of dust pollution will be generated when the blackboard is wiped, which poses a huge threat to the health of teachers and students. And current blackboard and blackboard eraser can't solve this problem, for this reason, we design a kind of multifunctional blackboard eraser to solve the above-mentioned problem very important.

Contents of the invention

The purpose of the utility model is to provide a multifunctional eraser, which is used to solve the problem that ordinary erasers cannot absorb chalk dust.

In order to achieve the above-mentioned purpose, the utility model multifunctional board eraser includes a board surface and a pull rod, and two parallel slideways are set up at the position close to the upper and lower ends of the board surface; Connection; Paste multiple strips of cleaning cotton at equal intervals on the surface of the pull rod, install a vacuum cleaner inside the pull rod, and process dust suction holes on the surface of the pull rod at the corresponding intervals of cleaning cotton.

After adopting the above structure, while wiping the blackboard, the user turns on the power of the vacuum cleaner, then moves the handle bar left and right, and wipes the chalk writing with the cleaning cotton. If a large amount of chalk dust is generated, the vacuum cleaner absorbs the chalk dust from the suction hole. , to avoid flying dust.

The utility model has the advantages of reasonable structure, wide application, simple process and low manufacturing cost, can improve wiping efficiency, and can keep indoor sanitation.
