Problems solved by technology

[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 throat, nose, and throat, and even cause pneumonia or respiratory diseases in severe cases.

Abstract

The invention discloses a blackboard eraser capable of reducing dust pollution. The blackboard eraser comprises a shell, bristle mechanisms, a first splitter plate, a second splitter plate and a dust suction mechanism. A containing space is arranged in the shell. Each bristle mechanism comprises a mounting plate, bristles and a connecting pipe, wherein the mounting plate is arranged below the shell, a containing cavity is formed in the mounting plate, a plurality of dust suction holes are formed in the bottom wall of the mounting plate and communicate with the containing cavity, and the bristles are mounted on the bottom wall of the mounting plate. The first splitter plate and the second splitter plate are arranged in the containing space of the shell and divide the containing space into a first web cavity, a second web cavity and a third web cavity from top to bottom. The first end of each connecting pipe communicates with the containing cavity in the corresponding mounting plate, and the second end of each connecting pipe communicates with the third web cavity. A first air inlet hole, a second air inlet hole and a third air inlet hole are sequentially formed in the first splitter plate. According to the blackboard eraser, dust can be prevented from flying, the content of chalk dust in air is reduced, the teaching environment is beautified, and environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of teaching supplies, in particular to a blackboard eraser for reducing dust pollution. 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. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a blackboard eraser that reduces dust pollution, which is easy to use and convenient for teaching. [0004] A blackboard eraser for reducing dust pollution, comprising a housing, a bristle mechanism, a first partition, a second partition, and a dust suctio...
