Abstract

PURPOSE: A chalkboard eraser is provided to protect a user from the generation of a respiratory disease by inserting a moisture-contained sponge inside the chalkboard eraser in order to intake dust generated from a chalk. CONSTITUTION: A rod shaped chalkboard eraser(1) is mounted to a handle. A moisture-contained sponge(2) with a groove is detachably inserted in the middle of the chalkboard eraser. The length of the chalkboard eraser is longer than that of the moisture-contained sponge. When a chalkboard is cleaned using the chalkboard eraser, dust generated from a chalk is attached to the moisture-contained sponge.

Description

먼지를 줄여주는 분필 칠판 지우개{chalkboard eraser without dust}Chalk eraser without dust

분필가루가 수분에 달라붙는다는 점을 이용.Take advantage of the fact that chalk sticks to moisture.

분필가루는 자연히 수분에 붙으면 떨어지지 않음.Chalk powder will not fall off if it sticks to moisture.

기존의 칠판을 지울때 분필가루가 많이 날리며 지우개를 털때 분필가루가 많이 날리는것을 해결하고자 함When you erase the old board, a lot of chalk is blown, and when you erase the eraser, you want to solve a lot of chalk.

물이 머금은 스펀지를 가운데에 삽입하여 공중으로 날아갈 분필가루들을 흡수할 수 있도록 하였음A sponge filled with water was inserted in the center so that it could absorb the chalk dust that would fly into the air.

칠판을 지울때 주변으로 날리는 분필가루나 지우개를 털때 심하게 날리는 분필가루를 물이 머금은 스펀지가 흡수해주고, 칠판을 털 필요없이 빨거나 교체하는 편리함이 있음When the board is erased, it is absorbed by the sponge that is blown around or the sponge that is badly blown when the eraser is shaken, and it is convenient to suck or replace the board without having to shake it.

칠판지우개의 손잡이에 물을 머금은 스펀지보다 조금 더 긴 막대기 모양의 지우개를 만들고 홈이 패인 물이 머금은 스펀지를 그곳에 끼운다. 그럼으로써 칠판을 쓸어내리며 지울 수 있고, 이때 발생하는 분필가루는 자연스럽게 물이 머금은 스펀지에 붙도록 하였다Make a stick-shaped eraser that is a little longer than a sponge with water on the handle of the blackboard eraser and insert a sponge filled with water. This allows the board to be swept away and erased, and the chalk powder that is generated naturally sticks to the sponge with water.

(1)의 칠판을 지울 수 있는 부분을 (2)물을 머금은 스펀지에 끼워서 한세트가 되는 구조이다.(1) The board can be erased, and (2) the sponge is filled with water.

Claims (2)

물을 머금은 스펀지를 가운데에 삽입한 것.A sponge filled with water is inserted in the middle. 물을 머금은 스펀지를 본체의 칠판지우개와 탈,부착이 가능하여 교체할 수 있는것.It is possible to replace the sponge with water with the blackboard eraser of the main body.
