Description

A vacuum cleaner

Technical Field

The utility model relates to the technical field of blackboard erasers, in particular to the improvement of the dust-absorbing eraser structure.

Background Art

Blackboard erasers are tools used to erase chalk writing on blackboards. When traditional blackboard erasers erase chalk writing, chalk dust directly flies into the air, which affects the health of teachers and students after inhalation. Therefore, various vacuum erasers are proposed in the prior art, such as the vacuum eraser board and its use method proposed in the Chinese invention patent with patent number "ZL201610390697.7". The eraser board drives the brush of the eraser board to rotate through a motor to erase the chalk writing, and the wiped dust is sucked into the dust storage box through the filter plate at the bottom thereof through a negative pressure generator. When actually wiping the blackboard, most of the dust is wiped off by the outer edge bristles, and the dust spreads to the surroundings with the impact of the outer edge bristles. However, the above-mentioned vacuum eraser board only relies on the filter holes of the filter plate to absorb dust. Most of the filter holes are gathered in the middle of the eraser board, and the number of filter holes at the edge of the eraser board is small, so the existing eraser board cannot absorb dust efficiently.
