Abstract
The utility model relates to a dust-absorbing board eraser comprising housing and an erasing felt plate arranged on the right surface of the housing. A power supply and a motor are arranged in the housing; an open is respectively arranged on the right surface and four lateral surfaces of the housing; a dust-absorbing fan is arranged at a place where the open is arranged of the housing; and a sensor device is disposed in the housing. The beneficial effects of the dust-absorbing board eraser are that flying dust is absorbed by the dust-absorbing eraser, thereby greatly reducing dust inhaled by teachers and students and further guaranteeing heath of teachers and students; and when the dust-absorbing eraser contacts with the blackboard and accelerate, the dust-absorbing fan in the dustless eraser is activated to work by the sensor device and no labor is needed to control the activation of the dust-absorbing fan, thereby improving blackboard erasering efficiency.
