Abstract

The invention discloses an environment-friendly blackboard for high school teaching. The environment-friendly blackboard for high school teaching comprises a fixed base, a writing board, an electric telescopic rod, a controller, a heat-dissipating fan, a brightness adjustor and a central processor, wherein the electric telescopic rod is mounted on the upper part of the fixed base; a blackboard shell is mounted at the upper end of the electric telescopic rod; the controller is mounted on the outer wall of the right side of the blackboard shell; a pen rack is mounted on the left side of the lower part of the blackboard shell; supporting rods are mounted on the left and right sides of the blackboard shell; rubber footings are mounted at the other ends of the supporting rods; the heat-dissipating fan is mounted on the outer wall of the back part of the blackboard shell; and a micro-fan is mounted in the heat-dissipating fan. The environment-friendly blackboard for high school teaching disclosed by the invention solves the problem that chalk dust generated in the using process affects the physical health of teachers and students and learning is affected as the teachers and students cannot see the blackboard clearly as a result of reflection.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to an environment-friendly blackboard for high school teaching. Background technique [0002] Because the blackboards used in various schools in our country are still mainly traditional blackboards, it is time-consuming and laborious to wipe the blackboards with blackboard erasers. Even if inhaled into the body, it affects mood and health. Inhaling too much chalk dust can cause discomfort in the pharynx, nose, and throat, and even cause pneumonia or respiratory diseases in severe cases. Due to the large number of students in the classroom, when the students sitting on the edge observe the blackboard, the observation is not clear due to the reflection of light, which makes teaching inconvenient and affects learning. Further improvement is needed. [0003] But existing teaching blackboard has following deficiency: [0004] 1. The existing blackboard for teaching is time-c...
