Abstract

The invention discloses a blackboard eraser with a quick cleaning structure, and belongs to the field of blackboard erasers. According to the blackboard eraser with the quick cleaning structure, a self-cleaning chain is arranged and can automatically move along the surface of cleaning cotton along with the wiping process, so that on one hand, the cleaning cotton is assisted to deeply clean a blackboard, and on the other hand, chalk dust attached to the surface of the cleaning cotton is absorbed; and meanwhile, the air at the inner side of an elastic pressing sleeve is promoted to repeatedly flow by tightly holding and extruding the elastic pressing sleeve with the hands, the chalk dust adsorbed by the self-cleaning chain is separated along with damp air flow and finally adsorbed by an adsorption layer, the desorbed self-cleaning chain circularly moves along the surface of the cleaning cotton, and the cleaning cotton and the blackboard are continuously and deeply cleaned, so that the cleaning cotton can continuously keep a certain wiping effect, the blackboard is effectively wiped, falling of the cleaning cotton and the chalk dust on the blackboard is reduced, and the healthy usability of the blackboard eraser is improved.

Description

technical field [0001] The invention relates to the field of blackboard erasers, more specifically, to a blackboard eraser with a quick-cleaning structure. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board surface is hard and is mostly used for teaching. With the development of multimedia technology, teaching is not as dependent on the blackboard as before, but in general teaching, the convenience of writing on the blackboard is still irreplaceable, and the blackboard eraser is still indispensable for classroom teaching. [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 seriousl...
