Rolling type dry and wet synchronous use efficient blackboard erasing method

Abstract

The invention provides a rolling type dry and wet synchronous efficient blackboard erasing method. The method comprises the steps that firstly, a blackboard is erased and cleaned; 2, a wiping assembly cleaning procedure; thirdly, the sliding assembly overturning procedure is synchronized with the second step; and fourthly, a cleaning mechanism returning procedure and a blackboard wiping and cleaning procedure are set, it is guaranteed that the blackboard can be wiped clean, dust cannot fly around, students and teachers are prevented from inhaling the dust, a wiping assembly cleaning procedure is set, the wiping assembly is cleaned, and a sliding assembly overturning procedure and the cleaning mechanism returning procedure are set, so that the cleaning efficiency of the blackboard is improved. The blackboard can be further cleaned, residual water on the blackboard can be blown dry, writing is prevented from being affected, and the problems that according to equipment for automatically erasing the blackboard, a sliding eraser is additionally arranged in the transverse direction, rapid and effective erasing cannot be achieved in the erasing process, meanwhile, a certain area of the blackboard is occupied, and the effect is poor are solved.

Description

technical field [0001] The invention relates to the technical field of teaching blackboards, in particular to a rolling-type dry-wet synchronous use and efficient erasing blackboard method. Background technique [0002] What most teaching institutions use at present is traditional blackboard, and it is made up of blackboard, chalk, blackboard eraser. There are the following problems: it needs to be wiped manually. For occasions with a large amount of teaching, most teachers need to wipe it by themselves, and the workload is heavy; at the same time, the chalk dust falling from wiping the blackboard will affect the health of teachers and students in the front row; The erasing method is often not clean, and the writing is not clear again. At present, some schools consider the health of teachers and students to promote the use of water-based pens, but water-based pens are inconvenient to write. Compared with ordinary chalk, it is more difficult to erase, and you need to wait fo...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the prior art, by setting a blackboard wiping and cleaning process, continuously spraying a small amount of water on the blackboard, and then wiping it, to ensure that the blackboard can be wiped clean, and the dust will not fly around, so as to avoid Students and teachers inhale dust, and when wiping, vacuum the blackboard to further prevent the dust from flying, and absorb the dust on the wiping surface of the wiping component to the inside, so that the wiping surface is clean enough to avoid weakening the wiping effect. The equipment for automatically erasing the blackboard is to add a sliding eraser horizontally. During the erasing process, it cannot be quickly and effectively erased, and it will occupy a certain area of ​​the blackboard, making the effect not good.
