Abstract
The utility model relates to an environment-friendly blackboard eraser which comprises an outer shell and a glass bottle, wherein a bottle mouth is arranged at the upper end of the glass bottle, and a water body is arranged in the glass bottle. A power source switch is arranged on the outer shell, and a fixing frame is arranged inside the outer shell. A dust brushing motor is fixedly connected on the fixing frame. A motor shaft is arranged at the lower end of the dust brushing motor. A ventilation hairbrush is fixedly connected at the lower end of the motor shaft. A flocking fixing ring is arranged at the position, along an edge, of the bottom end of the outer shell. A first ventilation hole is formed in one side of the outer shell and in connection with the upper end of a ventilation flexible pipe at the position along an inner edge in a sealed mode. The ventilation flexible pipe is in connection with an air drafting motor which is connected with the bottle mouth. The lower end of the ventilation flexible pipe is arranged in the water body. The environment-friendly blackboard eraser has the advantages that due to the design of the dust brushing motor, the ventilation hairbrush and a shock absorption spring, a blackboard can be quickly and conveniently erased, and time and labor are saved. Due to the design of the air drafting motor, the water body, the glass bottle and the ventilation flexible pipe, chalk dust can be fully absorbed, and secondary pollution can be avoided. The dust can be easily absorbed by water due to the design of a filter screen, and the blackboard eraser is green and environment-friendly.
