Abstract
The utility model discloses a dust absorption blackboard eraser which comprises a hair brush seat. A hair brush is fixedly arranged on the hair brush seat. A dust absorption cover is connected with the top of the hair brush seat in a buckled mode. The dust absorption cover is divided into a dust absorption cavity and a dust collection cavity through an L-shaped separating plate. A dust absorption device is arranged in the dust absorption cavity. The dust absorption device is in electric connection with a control switch outside the dust absorption cover. A dust filtering device is fixed between the separating plate and the dust absorption cover. An air outlet is formed in the wall of the dust absorption cover corresponding to the dust filtering device. Dust collection holes are formed in the separating plate and communicated with the dust collection cavity. Dust absorption holes which are communicated with the dust absorption cavity are formed in the hair brush seat. When the dust absorption blackboard eraser is used for erasing a blackboard, the dust extraction device begins to work by turning on the control switch, dust enters into the dust absorption cavity through the dust absorption holes, air pressure in the dust absorption cavity is increased, air is automatically exhausted through the air outlet, the dust is filtered when the dust passes the dust filtering device, the dust is dropped into the dust collection cavity through the dust collection holes after the dust is accumulated, and thereby the dust is prevented from flying in a classroom and air quality of the classroom is improved.
