Problems solved by technology

[0002] The existing blackboard for teaching is a fixed single board, which can be used on one side and can be used again after wiping off the chalk writing. This type of teaching blackboard can be used again after the teacher or student wipes the chalk writing clean. When writing and wiping again, a large amount of chalk dust adheres to the blackboard eraser. If it is not removed, chalk marks will be left on the blackboard when wiping, which will affect students' reading. The chalk dust on the blackboard eraser is often removed by patting or knocking , the chalk dust flies up when you tap it, pollutes the environment, and is easily inhaled by people to affect your health, thus affecting the entire teaching environment, and the effect of wiping the blackboard is not very good

Abstract

The invention discloses a self-cleaning blackboard eraser. The self-cleaning blackboard eraser comprises a blackboard eraser body; the blackboard eraser body is connected with a blackboard body through a first driving mechanism and a second driving mechanism, a groove is formed in the side, close to the blackboard body, of the blackboard eraser body, and a plurality of erasing rollers are arrangedon one side of the interior of the groove, a supporting plate is arranged inside the groove, a brush is arranged on the side, close to the erasing rollers, of the supporting plate, a plurality of dust suction openings are formed in the side edge of the blackboard eraser body, an air pump is arranged on one side of the blackboard eraser body, a dust collection box is arranged at the bottom end ofone side of the blackboard eraser body, a blackboard eraser cleaning mechanism is arranged at the top end of one side of the front face of the blackboard body, and a sewage tank is arranged at the bottom end of the blackboard eraser cleaning mechanism. The self-cleaning blackboard eraser has the beneficial effects that the blackboard body can be automatically erased, dust can be absorbed when theblackboard body is erased, the situation that the health of teachers and students is affected due to dust falling is avoided, the blackboard eraser body can be automatically cleaned and dried, the structure is reasonable, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of blackboard erasers, in particular to a self-cleaning blackboard eraser. Background technique [0002] The existing blackboard for teaching is a fixed single board, which can be used on one side and can be used again after wiping off the chalk writing. This type of teaching blackboard can be used again after the teacher or student wipes the chalk writing clean. When writing and wiping again, a large amount of chalk dust adheres to the blackboard eraser. If it is not removed, chalk marks will be left on the blackboard when wiping, which will affect students' reading. The chalk dust on the blackboard eraser is often removed by patting or knocking , Chalk dust flies when beating, pollutes the environment, and is easily inhaled by people and affects health, thereby affecting the entire teaching environment, and the effect of wiping the blackboard is not very good. [0003] Aiming at the problems in the rela...
