    • A blackboard eraser including a cube having two semi-cylindrical grooves symmetrically arranged in a longitudinal direction therein, and a central brush atop an elevated surface formed between the two grooves. A longitudinal groove is defined underneath each of the send-cylindrical grooves, and equal-length side brushes, which are affixed to an inner surface of a lid, are respectively positioned in the longitudinal grooves. Two grooves are arranged adjacent to each end of the semi-cylindrical grooves, which provide for a shaft affixed to each end of a roller to dispose therein. The brushes and the rollers form the eraser, which are enclosed within a closed chamber between the lid and the two semi-cylindrical grooves. When erasing chalk dust from a blackboard, the chalk dust sticks to the rollers and is carried to the side brushes. The side brushes then wipes the dust, which falls into the closed chamber.
    • 一种黑色橡皮擦,其包括具有两个在其纵向方向上对称布置的两个半圆柱形凹槽的立方体,以及在形成在两个凹槽之间的升高表面顶部的中心刷。 纵向槽限定在每个发送圆柱形槽的下方,并且固定到盖的内表面的等长侧刷分别位于纵向槽中。 两个凹槽布置成邻近半圆柱形凹槽的每个端部,其提供固定到辊的​​每个端部以设置在其中的轴。 刷子和辊子形成橡皮擦,其被封闭在盖和两个半圆柱形凹槽之间的封闭室内。 当从黑板上擦去白垩灰尘时,粉笔尘土粘在滚筒上,并被带到侧刷上。 侧刷然后擦拭落入封闭室内的灰尘。

    • A novel structure for a blackboard eraser is provided wherein the eraser comprises a plurality of raised rows of two or more different erasing mediums such as brushes, fiber or cloths laterally spaced and extending parallel on a base support to form an eraser body. The body is connected at its two ends to a resilient dust-collecting frame flush with the raised erasing mediums so that when erasing the blackboard with the eraser the latter completely encloses the corresponding part of the blackboard, guiding the dust along the spaces between adjacent raised rows of erasing mediums and then collecting them in the frame, thereby preventing the dust from flying about and polluting the air. A chalk container may further be formed at the lower part of the eraser for holding the chalks.
    • 提供了一种用于黑板橡皮擦的新颖结构,其中橡皮擦包括两个或更多个不同的擦除介质的多个凸起的行,例如刷子,纤维或布横向间隔开并平行于基座支撑延伸以形成橡皮擦体。 主体的两端连接到与升高的擦除介质齐平的弹性集尘框架上,以便当用橡皮擦擦除黑板时,后者完全包围黑板的相应部分,沿着相邻凸起的空间之间的空间引导灰尘 一排擦除介质,然后将其收集在框架中,从而防止灰尘飞溅并污染空气。 可以在橡皮擦的下部进一步形成粉笔容器以保持白垩。
