BLACKBOARD ERASER CLEANING DEVICE CAPABLE OF NOT SCATTERING A POWDER WHICH IS PILED UP WITH A SLOW AIRFLOW

摘要

PURPOSE: A blackboard eraser cleaning device is provided to block a flow out of a scattering powder which is inhaled, and rapidly inhale the scattering powder which is generated in the blackboard eraser without leakage to the outside.;CONSTITUTION: A blackboard eraser cleaning device comprises: a powder scattering part (101) which pushes through a scattering powder of a blackboard eraser which is generated by rubbing or hitting the blackboard eraser with a grid net which is installed with divided in the predetermined space; a high speed intake inducing part (104) which induces the scattering powder to a direction of bottom surface by guiding to a inclined plate in which a width is gradually narrowed to a downward direction; a back flow prevention shield (F) which provides an air path by bending while inhaling the scattering powder with high speed, closes and blocks the air path with restoring force while stopping the inhaling; and a low speed precipitation storage compartment (102) which stores scattering powder which is inhaled from the back flow prevention shield with the low speed precipitation.;COPYRIGHT KIPO 2013
