Abstract
The utility model provides a dust-sucking plant for a blackboard eraser. The technical scheme is that: the blackboard eraser provided with a dust-sucking hole and a brush is connected with a household dust collector through a dust-sucking pipeline. The blackboard eraser consists of a casing, a shell, the brush, the dust-sucking hole and a handle; the brush and the dust-sucking hole are arranged on the bottom of the blackboard eraser; and the dust-sucking hole is communicated with an inner cavity of the shell. When the dust-sucking plant is used, the handle of the blackboard eraser is held by hands, the dust collector is started, and a user can erase the writing of chalks left and right and up and down. The dust-sucking plant for the blackboard eraser has the advantages that: in the using process of the user, the chalk dust enters the dust collector under the action of the dust collector so as to effectively prevent chalk dust from polluting environment.
Description
