Blackboard cleaning system

Abstract

The invention discloses a blackboard cleaning system, and belongs to the technical field of teaching tools. The blackboard cleaning system comprises a blackboard, a containing tank, a wall, a power source and a transmission belt. The blackboard is arranged on the wall, and the power source is connected with a single-chip microcomputer. A spraying head is arranged at the top of the blackboard, andthe rear portion of the spraying head communicates with a solenoid valve through a water pipe. The solenoid valve communicates with a water supply tank, and a water pump I is arranged between the water supply tank and the solenoid valve. The water pump I and the solenoid valve are both electrically connected with the single-chip microcomputer. A drainage channel is arranged at the bottom corner ofthe blackboard, and communicates with a waste water pool. A wiping body is arranged on the front side of the blackboard, a transmission rod is arranged on the transmission belt, and the transmissionrod is connected with a sliding sleeve. A transmission wheel is arranged on the inner side of the transmission belt, and the single-chip microcomputer is electrically connected with two rotary motors.The output ends of the rotary motors are connected with the input end of a reducer, and the output end of the reducer is connected with a transmission wheel. The blackboard cleaning system is easy and convenient to operate, the blackboard can be automatically wiped and cleaned, the wiping process is free of dust, the health of teachers and students cannot be influenced, the labor intensity is low, and the work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, and in particular relates to a blackboard cleaning system for wiping a blackboard. Background technique [0002] In the current teaching process, the blackboard is an essential teaching auxiliary facility. There are many types of blackboards, including traditional cement blackboards, frosted glass blackboards, iron blackboards, and polymer blackboards. During teaching, chalk or other pens are generally used to write directly on the blackboard for teaching. After the writing on the blackboard is completed, the handwriting on the blackboard needs to be wiped clean before writing on the blackboard again. The commonly used wiping tool is a blackboard eraser or other wiping tools, but sometimes The amount of writing on the blackboard is large, the workload is heavy, and the dust is adsorbed on the board and it is difficult to wipe clean. Over time, more and more dust is deposited on and ar...

Problems solved by technology

During teaching, chalk or other pens are generally used to write directly on the blackboard for teaching. After the writing on the blackboard is completed, the handwriting on the blackboard needs to be wiped clean before writing on the blackboard again. The commonly used wiping tool is a blackboard eraser or other wiping tools, but sometimes The amount of writing on the blackboard is large, the workload is heavy, and the dust is adsorbed on the board and it is difficult to wipe clean. Over time, more and more dust is deposited on and around the blackboard, which seriously affects the respiratory health of the lecturers and the quality of teaching. Wiping not only consumes physical strength , It takes a long time, and it is easy to cause dust to fly during the wiping process, which seriously affects the health of teachers and students and affects teaching. At this time, it is necessary to design a blackboard cleaning system that automatically cleans the blackboard
