Novel dustproof blackboard eraser

Abstract

The invention discloses a dustproof blackboard eraser. The dustproof blackboard eraser comprises a blackboard eraser body, the blackboard eraser body comprises a shell body, and a brush body used forerasing chalk writing is connected to the outer side face of the shell body; the dustproof blackboard eraser further comprises a cover body, the blackboard eraser body is located in the cover body, and a distance is reserved between the outer surface of the blackboard eraser body and the inner wall face of the cover body; and an outer shell is connected between the shell body and the bottom of thecover body, the brush body extends out of the cover body, a fogging assembly with an atomizing spray head is installed in the outer shell, the atomizing spray head is located on the outer side face of the outer shell to spray water mist towards the inner space of the cover body, a water tank with a water injection port is arranged in the cover body, and the water tank is connected with the atomizing spray head through a water guiding device. Chalk dust can be prevented from flying around quickly, dust can be reduced quickly, and the dust removal effect is better.

Description

technical field [0001] The invention relates to a blackboard eraser, more specifically to a dustproof blackboard eraser, which belongs to the field of teaching appliances. Background technique [0002] When the traditional blackboard eraser is used to wipe the blackboard, the chalk dust will scatter and pollute the classroom environment, dirty the user's whole body, and will be inhaled into the body, causing harm to the health of teachers and students. Wiping the blackboard with a damp cloth can reduce dust scattering to a certain extent, but it is necessary for students on duty to clean the cloth between classes. ;If the rag is not cleaned, it is easy to cause a big face; it is more uncomfortable to clean the rag in autumn and winter; during the cleaning process, the dust is more likely to be absorbed on the hands of students, which will also have a certain impact on health. [0003] At present, the solution to blackboard wiper flying dust technology is mainly achieved by ...

Problems solved by technology

[0002] When the traditional blackboard eraser wipes the blackboard, the chalk dust will scatter and pollute the classroom environment, dirty the user's whole body, and will be inhaled into the body, causing harm to the health of teachers and students

Wiping the blackboard with a damp cloth can reduce dust scattering to a certain extent, but it is necessary for students on duty to clean the cloth between classes. ;If the rag is not cleaned, it will easily cause a big face; it will be more uncomfortable to clean the rag in autumn and winter; during the cleaning process, the dust will be more likely to be absorbed on the hands of students, which will also have a certain impact on health

[0003] At present, the solution to blackboard wiper flying dust technology is mainly achieved by improving two aspects: one is to set up a dust suction structure, but the structure is relatively complicated, and some even need to renovate the entire blackboard, which is more complicated and costly; Spray water and wipe it with a rag. In this way, excess water will remain on the blackboard. Water and chalk powder will form an uneven mixed liquid on the surface of the blackboard. After the water evaporates, white marks will be left on the blackboard, and the blackboard will be wading too much not conducive to immediate reuse
