Abstract

The invention discloses a dust-absorbing blackboard eraser, which comprises a blackboard eraser back cover and bristles, an ash storage box is installed on the inner surface of the blackboard eraser back cover, and a micro-vacuum cleaner is installed at the ash inlet of the ash storage box. The roots of the bristles are bonded with metal wire mesh, and the dust suction port of the micro-vacuum cleaner is closely attached to the metal wire mesh. The blackboard eraser has a dust suction function, can effectively prevent dust pollution, and reduce harm to human body.

Description

technical field [0001] The invention relates to the field of blackboard erasers, in particular to a dust-absorbing blackboard eraser. Background technique [0002] A blackboard eraser is a tool commonly used by teachers in the teaching process to erase chalk traces for secondary writing. Ordinary blackboard erasers have a simple structure and only have a general erasing effect. They are prone to generate a lot of dust during use, and the effect will be affected by dust condensation after long-term use. Contents of the invention [0003] The object of the present invention is to provide a dust-absorbing blackboard eraser, which has a dust-absorbing function, can effectively prevent dust pollution, and reduce harm to the human body, so as to solve the problem of low efficiency and high labor intensity of the common processing device proposed in the above-mentioned background technology. question. [0004] In order to achieve the above object, the present invention provides...
