Abstract

To disclose a dust-proof blackboard eraser.SOLUTION: The dust-proof blackboard eraser includes a box body. A placing chamber that opens downward is installed in the box body. A blackboard eraser is placed in the placing chamber. In the blackboard eraser, hooking grooves are installed symmetrically. The screw chambers are installed symmetrically in the placement chamber so as to communicate with each other. When the blackboard eraser moves on the blackboard, a ring sticks to the blackboard and rotates. The ring rotates and causes a power rod to be interlocked and rotated. The power rod rotates and causes a third gear to be interlocked and rotated. The third gear causes a connecting rod and a first bevel gear to be interlocked and rotated with a second chain. When the blackboard eraser moves and wipes the blackboard, it operates in conjunction with a dust suction mechanism and sucks chalk powder that has been generated, avoiding the chalk powder scattering. The entire device does not need to be driven by a motor, thereby saving electricity.SELECTED DRAWING: Figure 1

Description

本発明は文具分野を取り上げて、具体的には防塵黒板消しである。 The present invention takes up the field of stationery, and specifically is a dustproof blackboard eraser.

一般的な黒板消しは防塵機能を有しないので、黒板消しを使用する時、いつも多くのチョークの粉が生じ、チョークの粉が教室に舞い散り、学生に吸い込まれた後、学生の体の健康に悪影響を与え、一般的な吸塵黒板消しがチョークの粉を吸い込む時にモータにより駆動される必要があり、電力資源を浪費する。 Since a general blackboard eraser does not have a dustproof function, when using a blackboard eraser, a lot of chalk powder is always generated, and after the chalk powder is scattered in the classroom and sucked by the student, the student's physical health A common dust-absorbing blackboard eraser needs to be driven by a motor when sucking chalk powder, wasting power resources.
