Problems solved by technology

[0003] Existing blackboard eraser is in the process of wiping blackboard, and blackboard eraser will be stained with chalk dust very soon, makes wiping effect reduce greatly, and, when the chalk dust attached on blackboard eraser is too much, the chalk on blackboard and blackboard eraser The ash will fall seriously, so it is easy to be inhaled by the user too much, causing great harm to the body

Abstract

The invention discloses a blackboard eraser with a quick cleaning structure, belonging to the field of blackboard erasers, and a blackboard eraser with a quick cleaning structure. On the one hand, it assists the cleaning cotton to achieve deep cleaning of the blackboard, and on the other hand, it realizes the adsorption of the chalk dust adhered to the surface of the cleaning cotton. The repeated flow of air makes the chalk ash adsorbed by the self-cleaning chain detached with the moist air flow, and finally adsorbed by the adsorption layer, and the desorbed self-cleaning chain moves along the surface of the cleaning cotton cyclically, continuously realizing the depth of the cleaning cotton and the blackboard. Therefore, the cleaning cotton can maintain a certain degree of wiping effect continuously, realize the effective wiping of the blackboard, reduce the falling of the cleaning cotton and the chalk ash on the blackboard, and improve the healthy usability of the present invention.

Description

technical field [0001] The present invention relates to the field of blackboard erasers, more particularly, to a blackboard eraser with a quick cleaning structure. Background technique [0002] A blackboard does not specifically refer to a black surface. Traditionally, it is a flat surface that can be written repeatedly with chalk. The surface is hard and is mostly used for teaching. With the development of multimedia technology, teaching does not rely on the blackboard as before, but in general teaching, the convenient writing feature of the blackboard is still irreplaceable, and the blackboard eraser is still indispensable in classroom teaching. [0003] When the existing blackboard eraser is in the process of rubbing the blackboard, the blackboard eraser will soon be covered with chalk dust, which greatly reduces the wiping effect. The ash will fall seriously, so that it is easy to be inhaled by the user too much, causing great harm to the body. SUMMARY OF THE INVENTIO...
