Abstract

The invention discloses a self-cleaning blackboard eraser. The self-cleaning blackboard eraser comprises a housing which is a box structure with both ends open, the upper end of the housing is provided with a cover in a clamping mode, the lower end of the housing is provided with a wiping module in a fastened mode, the middle of the housing is provided with a cleaning module which is in contact with the wiping module. The self-cleaning blackboard eraser cleans chalk dust through the closed housing to prevent the dust from floating in air and further to achieve cleaning effects; a cleaning wheel and a hitting pendulum are arranged for cleaning a wiping cloth to ensure the cleaning effects of the wiping cloth; walking wheels made of rubber or soft plastics can prevent the wiping cloth from soiling a flat surface when the self-cleaning blackboard eraser is not in use to ensure cleanliness of the flat surface and meanwhile avoid skidding between the walking wheels and the surface of the blackboard, thereby ensuring the cleaning effects.

Description

technical field [0001] The invention belongs to the technical field of teaching tools, in particular to a self-cleaning blackboard eraser. Background technique [0002] Usually teachers use chalk to write on the blackboard for teaching, and use blackboard eraser to wipe. Because the amount of chalk dust produced by chalk is a lot, chalk dust often falls while wiping the blackboard, causing air pollution, directly endangering the health of teachers and students, and causing occupational diseases of teachers when serious; and due to the chalk on the blackboard eraser Too much dust causes the blackboard eraser to be unclean, which affects writing and reading. It is necessary to pat the chalk dust on the blackboard eraser frequently before continuing to use it; of good health. Contents of the invention [0003] According to the above deficiencies in the prior art, the technical problem to be solved by the present invention is to propose a self-cleaning blackboard eraser. ...
