Abstract

본 발명은 백묵가루 수집장치에 관한 것으로, 특히 흡입장치 선단에 연결되는 호스 끝단부에 백묵끼움구를 연결하여 칠판에 백묵을 사용할 시 발생되는 가루를 흡입장치에 흡입될 수 있도록 함과 동시에, 칠판 지우개를 백묵끼움구와 교체하여 칠판을 지울 때 발생되는 가루를 흡입장치에 흡입하도록 하므로서 백묵가루로 인한 인체의 악영향을 배제하고, 이에 따라 칠판주변의 공기오염을 줄일 수 있도록 한 것이다.The present invention relates to a chalk powder collecting device, in particular by connecting the chalk fitting hole to the end of the hose connected to the tip of the suction device to allow the suction of the powder generated when using chalk on the blackboard, and at the same time, the blackboard By replacing the eraser with chalk inserts, the dust generated when the board is erased is sucked into the suction device, thereby eliminating the adverse effect of the human body caused by chalk powder, and thus reducing the air pollution around the board.
