Embodiment Construction

[0023] See attached figure 1 As shown, a kind of teaching writing equipment described in the present invention includes a blackboard and a blackboard eraser. The blackboard includes a blackboard body 1 and an inclined blackboard surface 2. The inclined blackboard surface is provided with dust collection holes 3. The blackboard The main body 1 is provided with a hollow dust collection chamber, and the collection hole 3 on the blackboard surface 2 communicates with the dust collection chamber. When wiping the blackboard like this, chalk dust falls in the dust collection cavity of blackboard body 1 from dust collection hole 3.

[0024] The inclination angle of the inclined blackboard surface 2 is 25-45 degrees. In this way, excessive inclination angles are avoided, resulting in the risk that the writing on the blackboard surface is not easily seen by the students below, and the inclination angle in this range is conducive to chalk dust. Fall into the collection hole 3. In this ...

Abstract

The invention discloses writing equipment for teaching. The writing equipment for teaching comprises a blackboard and a blackboard eraser, wherein the blackboard comprises a blackboard body and an inclined blackboard surface; dust collecting holes are formed in the inclined blackboard surface; a hollow dust collecting cavity is formed in the blackboard body; and the collecting holes of the blackboard surface communicate with the dust collecting cavity. Therefore, when the blackboard is erased, dust of chalks drops into the dust collecting cavity via the dust collecting holes, pollution of dust to the environment of teachers is reduced, and therefore, the writing equipment for teaching is safe.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an inclined blackboard teaching writing equipment with dust collecting holes. Background technique [0002] At present, chalk and blackboard are the main classroom teaching writing tools in school teaching, but when the traditional blackboard is wiping the blackboard, the friction between the blackboard and the blackboard eraser will produce a lot of chalk dust, pollute the air in the classroom, and cause serious damage to the health of teachers and students. great harm. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a teaching writing device capable of collecting chalk dust. [0004] The technical scheme adopted by the present invention is as follows. [0005] A writing device for teaching, comprising a blackboard and a blackboard eraser. The blackboard includes a blackboard body and an inclined blackbo...
