Problems solved by technology
[0002] The application of multimedia teaching aids is becoming more and more widespread, but it still cannot replace the traditional teaching method of writing and teaching with chalk. In daily teaching work, using chalk can write corresponding teaching information at any time according to needs. Chalk is the simplest and most direct method. Teaching tools, general classrooms will be equipped
[0003] However, writing with chalk will lead to the generation of dust. When using a blackboard eraser to wipe the blackboard, chalk dust will fly in the air, and teaching staff can easily inhale the dust. The dust accumulates in the lungs of the user and cannot be discharged. It will be damaged, and it will have a huge impact on the health of teaching staff, etc.

The invention discloses an automatic dust suction blackboard eraser. The automatic dust suction blackboard eraser comprises a frame. The outer side of the frame is provided with a groove. The upper and lower inner walls of the groove are symmetrically provided with main plastic plates. The left and right inner walls of the groove are symmetrically provided with auxiliary plastic plates. The frameis internally provided with an active moving mechanism and a pair of auxiliary moving mechanisms; the two auxiliary moving mechanisms are symmetrically arranged on the two sides of the active moving mechanism. The active moving mechanism comprises a main rubber sheet and a main fur. Each auxiliary moving mechanism comprises an auxiliary rubber sheet and an auxiliary fur. The main rubber sheet andthe auxiliary rubber sheets are all fixedly connected with the frame. The automatic dust suction blackboard eraser enables a rotary shaft to drive the main fur and the auxiliary furs to rotate in therotating process under blackboard wiping actions and the inertia effect; the main fur has mutual friction with the main rubber sheet, the auxiliary furs have mutual friction with the auxiliary rubbersheets, and the main rubber sheet and the auxiliary rubber sheets can carry negative charge to adsorb dust through electrostatic interaction.
Description
technical field [0001] The invention relates to the technical field of blackboard erasers, in particular to an automatic dust-absorbing blackboard eraser. Background technique [0002] The application of multimedia teaching aids is becoming more and more widespread, but it still cannot replace the traditional teaching method of writing and teaching with chalk. In daily teaching work, using chalk can write corresponding teaching information at any time according to needs. Chalk is the simplest and most direct method. Teaching tools are generally equipped in classrooms. [0003] However, writing with chalk will lead to the generation of dust. When using a blackboard eraser to wipe the blackboard, chalk dust will fly in the air, and teaching staff can easily inhale the dust. The dust accumulates in the lungs of the user and cannot be discharged. It will be damaged, and it will have a huge impact on the health of teaching staff.
