Abstract

The invention discloses a classroom blackboard dust collection system. The classroom blackboard dust collection system comprises a blackboard main body, and pipeline bodies are correspondingly fixed to the upper portion of the blackboard main body and the wall faces of the left side and the right side of the blackboard main body; and an air suction and guide pipe is inserted into the upper pipeline body in a sleeved mode, and the two ends of the air suction and guide pipe extend into the pipeline bodies on the left side and the right side; vertical air suction and guide pipes are inserted intothe pipeline bodies on the left side and the right side in a sleeved mode, and the two ends of the vertical air suction and guide pipes are fixed to top plates and bottom plates of the pipeline bodies on the left side and the right side. According to the classroom blackboard dust collection system, when a blackboard is wiped, dust floating around the front of the blackboard can be adsorbed and filtered, so that pollution to the surrounding environment is reduced, and environmental sanitation is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of teaching appliance manufacturing, and more particularly to a classroom blackboard vacuuming system. Background technique [0002] When the blackboard is in use, it will generate a lot of dust when wiping the content written by chalk. The existing method is to set a powder drop hole at the bottom of the blackboard at the pen slot to collect the dropped dust. However, when wiping , There will be floating dust in front of the blackboard. At this time, it cannot be dealt with immediately, and it will float in the air and affect the surrounding environment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a classroom blackboard dust collection system, which can absorb and filter the floating dust around the front of the blackboard when wiping the blackboard, thereby reducing the pollution to the surrounding environment...
