Abstract

A baffle-type eraser comprises a frame. Fixed screws are installed on the frame, a blackboard is installed in the frame, a water spraying hole is formed in the blackboard, micro motors are installed on the frame, and the micro motors are connected with brushes. The baffle-type blackboard eraser is full automatic, and the number and the angle of the installed brushes can be determined according to the length of the blackboard. Relevant buttons are arranged on a platform to control the micro motors, and the problem that some contents which should not be erased are erased is solved. In addition, an independent remote control is further provided, so that a teacher can control erasing of the blackboard remotely in the walking process and does not need to go back to the platform, and many troubles are saved. The eraser has two types, the eraser of one type is applicable to a white board, and the brushes are made of common cotton; the eraser of the other type is applicable to the blackboard, and the brushes are made of a material identical with that of an automobile baffle brush and are thicker than the brushes of the white board. Therefore, the teacher can erase the blackboard conveniently and can prevent toxic dust pollution.

Description

1. Technical field [0001] The invention relates to a blackboard eraser which can be cleaned automatically, in particular to a baffle type blackboard eraser which is connected with a brush by a micro-motor. 2. Background technology [0002] Although teachers are engineers of people's minds, it is an enviable profession, but for a long time, they have to be exposed to a lot of chalk dust every day, which affects their health. If the body inhales chalk dust every day, it will cause diseases over time. Blackboard writing is a bridge for teachers to spread knowledge, but it is not easy to wipe it off, and it will also produce toxic dust. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a blackboard eraser that can be cleaned automatically, in particular to a baffle type blackboard eraser that connects brushes with a micro-motor. [0004] The technical solution adopted by the present inventio...
