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

Embodiment 1
[0028] The following is a description of Embodiment 2.
[0029] Such as Figure 1 to Figure 5 As shown, a blackboard cleaning system includes a blackboard 1, a holding tank 11, a spray head 2, a water supply tank 21, a water pump I22, a drainage channel 3, a waste water pool 31, a wiping body 4, a reflector 5, and an electric heating radiator 51 , power supply 6, single-chip microcomputer 7, rotary motor 71, speed reducer 72, solenoid valve 73, transmission belt 8, transmission wheel 81, transmission rod 811, body of wall 9, slide rail bar 91.
[0030] The blackboard 1 is arranged on the wall 9, the bottom of the blackboard 1 is provided with a holding groove 11, and the nozzle of the spray head 2 arranged on the top of the blackboard 1 faces the upper part of the blackboard 1, and the upper part of the blackboard 1 corresponds to the position of the nozzle Grooves are arranged at the upper edge of the blackboard in the length direction.
[0031] The spray head 2 is aligned ...
Embodiment 2
[0038] The following is a description of Embodiment 2.
[0039] Embodiment 2 has been improved on the basis of Embodiment 1, retains the same structure, and omits the same description, such as Figure 6 As shown, the waste water pool 31 is connected to the waste water filter pool 33 through a pipeline, and a water pump II 32 is arranged between the waste water pool 31 and the waste water filter pool 33. The water pump II 32 is electrically connected to the single-chip microcomputer 7, and the waste water filter pool 33 is reconnected to the water supply tank 21 through pipelines, realizing resource reuse and protecting the ecological environment.
[0040] When the device uses the cleaning function, start the power supply 6, the built-in command of the single chip microcomputer 7 starts, and the command controls the operation of the water pump I22 and the solenoid valve 73, and the water flow is transmitted from the water supply tank 21 to the sprinkler head 2 and sprayed to th...

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...
