Abstract

A novel environment-friendly blackboard system comprises a blackboard frame, four blackboards, a blackboard wiping device and a dust and waste water recovery device. The four blackboards and the blackboard wiping device are arranged on the blackboard frame. The blackboards can move in the blackboard frame. The blackboard frame comprises six vacancies, the four blackboards are located in four of the vacancies of the blackboard frame correspondingly, and the rest of two vacancies including no blackboard can facilitate blackboard movement. A chalk dust groove is arranged below the blackboards andis located at the bottom of the blackboard frame, so that chalk dust generated in the writing process falls into the chalk dust groove. The blackboard wiping device is located on the left side or theright side of the blackboard frame and comprises a dust cover, a wet wiping mechanism and a dry wiping mechanism. The wet wiping mechanism and the dry wiping mechanism are located in the dust cover.The wet wiping mechanism is located below the dust cover. The dry wiping mechanism is located above the dust cover. A water collection groove is further arranged under the wet wiping mechanism and located on the blackboard frame. The dust and waste water recovery device is arranged below the blackboard wiping device.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a novel environment-friendly blackboard system. Background technique [0002] The blackboard is used frequently in the teaching process, and the chalk consumed is difficult to count. Chalk will produce a lot of chalk dust during the writing and erasing process, which affects the air quality. At the same time, hands are easy to get dirty. It is not uncommon to wash hands and hair because of chalk dust, which consumes more water resources. Chalk has a very large number of chalk heads after use, and is generally all thrown out as rubbish. Although calcium carbonate and calcium sulfate used in making chalk are not scarce resources, they should not be wasted. Contents of the invention [0003] In view of this, it is necessary to provide a novel environment-friendly blackboard system which is not easy to generate dust and saves chalk. [0004] A new environment-friendly bla...
