Problems solved by technology
[0003] The existing board eraser cleaning machine has disadvantages in use. The beating board eraser causes a lot of calcium carbonate dust and the water storage capacity of the water wiping board eraser is insufficient (there is no water in less than one class), the water is turbid and water is added frequently, the water is turbid and cannot be wiped clean, and the blackboard becomes dirty. Dirty, easy to stain teacher's sleeves

Description
Technical field: [0001] The invention relates to the technical field of blackboard eraser cleaners, in particular to an environment-friendly water-erasable blackboard eraser cleaner. Background technique: [0002] For now, the working environment for teachers is still relatively poor. Take blackboard writing as an example, mostly chalk and blackboard. Although many chalk packaging boxes are now marked with "dust-free chalk", a large amount of dust that cannot be absorbed by the human body is generated during actual writing and erasing, which seriously pollutes the teaching environment and affects the health of teachers and students, and students are responsible for cleaning the blackboard. The task is in the classroom from morning to night, and chalk dust is more harmful to the health of underage students with weaker resistance. Chalk dust flying is mainly because the chalk dust adhering to the blackboard eraser cannot be effectively removed and collected, resulting in lon...
