Abstract

The invention discloses a blackboard eraser capable of sucking dust synchronously. The front end of a blackboard eraser body (1) is provided with a dust suction pipe (2). The dust suction pipe (2) is provided with a dust suction hole. The dust suction pipe is connected with a negative-voltage motor (3). A collection basket (4) is connected to the tail end of the pipe. In the using process, chalk dust generated during movement of the blackboard eraser body is collected to the collection basket (4) through the dust suction pipe. An induction module (5) is arranged on the collection basket (4). When the collection basket is almost filled with the chalk dust, the induction module sends out a prompt message. The prompt message is displayed in the mode of sound or LED lamp light. The dust suction pipe (2) is of a twistable structure, and the position of the dust suction pipe (2) can be adjusted as needed. The diameter of the dust suction hole in the dust suction pipe (2) should be smaller than one millimeter. The dust suction pipe (2) is provided with a dismantling connector to facilitate separate use of the blackboard eraser body. By means of the blackboard eraser capable of sucking the dust synchronously, the air in a classroom can be kept clean, dust pollution can be reduced, and a good learning environment can be provided for students.

Description

technical field [0001] The invention relates to a teaching article. Background technique [0002] For the school classroom environment, the blackboard erasers in each classroom will generate dust when they are rubbed, and if the human body inhales a large amount, it will cause physical discomfort. If the blackboard eraser can integrate the dust collection function, the above problems will be effectively solved. Contents of the invention [0003] The object of the present invention is to provide a blackboard eraser which can absorb chalk dust immediately. [0004] The present invention is achieved like this. For a blackboard eraser with simultaneous vacuuming, a dust suction pipe is set at the front end of the blackboard eraser, and a dust suction hole is set on the dust suction pipe. The dust suction pipe is connected to a negative pressure motor, and the end of the pipe is connected to a storage basket. The chalk dust is collected into the collection basket through the...
