The utility model content

The utility model has overcome shortcoming of the prior art, and a kind of blackboard eraser with dust-absorbing function is provided.

To achieve these goals, the utility model is achieved through the following technical solutions: a kind of dust absorption blackboard eraser, comprise brush holder and be arranged on brush body on brush holder, be provided with inner chamber on brush holder, be provided with several through holes on brush body and communicate with the brush holder inner chamber, being provided with the dust exhaust apparatus with its intracavity inter-connection on described brush holder.

Preferably, described dust exhaust apparatus is the dust catcher of duster brush of dismantling, and the tube connector of dust catcher is communicated with the inner chamber of brush holder.

Preferably, the through hole on described brush body is strip.

Preferably, the through hole on described brush body is ring-type.

Preferably, the position that is connected with dust exhaust apparatus of described brush holder is provided with handle.

Compared with prior art, the utlity model has following advantage: because be provided with inner chamber on the brush holder of blackboard eraser, through hole is set on brush body and communicates with the brush holder inner chamber, be provided with the dust exhaust apparatus with its intracavity inter-connection on brush holder, therefore the dust under can wiping when erasing the board through the through hole of brush body, the inner chamber respirable dust device of brush holder, can not sucked by human body and be detrimental to health because of the diffusion of dust, can not pollute environment yet, and simple in structure, easy to use.
