Blackboard eraser cleaning device

Abstract

The invention discloses a blackboard eraser cleaning device. The blackboard eraser cleaning device comprises a box, a dust treating cavity and a dust collecting cavity, wherein a blackboard eraser storing opening is formed in the middle of the top of the box; a control switch is arranged on the box and on the left side of the blackboard eraser storing opening; a dust treating device is arranged in the dust treating cavity and comprises a driving wheel, a driven wheel and a belt; a motor and a water tank are respectively arranged on the outside of the dust treating cavity and on the outside of the dust collecting cavity and in the box; and fan blades are arranged on the left side wall of the water tank through a supporting rod. Dust on a blackboard eraser can be cleaned through bristles on the belt and is collected into a dust collecting bag in the dust collecting cavity, the dust on the blackboard eraser can be removed quickly and effectively, secondary pollution is avoided, lower portions of the fan blades soak in water in the water tank, after the water is atomized, atomized water is blown into the dust treating cavity, the dust is mixed with the atomized water, the dust collection efficiency is greatly improved, the dust is not scattered towards the outside of the box, and a good teaching environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a blackboard eraser cleaning device. Background technique [0002] In modern teaching, although projectors have been widely used, blackboards and chalk are still important tools in teaching, and still have an irreplaceable position in the classroom. Because the eraser will accumulate a lot of dust after use, the excess dust will seriously hinder the cleaning effect when it is used next time, but it is almost impossible to clean the eraser during class except for get out of class time. If it is not properly resolved, dust will fly in the classroom during the cleaning process, which will not only stain the desks, hair and clothes with a layer of white powder, but also emit a special smell, which will easily cause chronic pharyngitis, etc. Disease, which has brought great harm to the health of teachers and students.

Problems solved by technology

[0002] In modern teaching, although projectors have been widely used, blackboards and chalk are still important tools in teaching, and still have an irreplaceable position in the classroom. , because the board eraser will accumulate a lot of dust after use, the excess dust will seriously hinder the cleaning effect when it is used next time, but except for get out of class time, it is almost impossible to clean the board eraser during class

If it is not properly resolved, dust will fly in the classroom during the cleaning process, which will not only stain the desks, hair and clothes with a layer of white powder, but also emit a special smell, which will easily cause chronic pharyngitis, etc. disease, which has brought great harm to the health of teachers and students

[0003] Because the blackboard is attached too much and becomes a gray board, students cannot clearly see the writing on the blackboard. Experiments have proved that under the condition of normal use of the blackboard, the blackboard needs to be cleaned about 11 times a day, and there are nine months of courses in one school year. , a total of 2970 times of cleaning the board eraser is required, and this process cannot be completed in the classroom due to the huge dust
