Embodiment Construction

[0060] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0061] Such as Figure 1 to Figure 2 As shown, an automatic blackboard scrubbing device provided in this embodiment includes a guide rail device, a scrubbing part, and a controller. Wherein, the guide rail device includes an upper guide rail arranged above the blackboard and a lower guide rail arranged under the blackboard. The upper and lower guide rails are fixed inside the wall with screws, and the upper guide rail and the lower guide rail are parallel to each other. , Cleaning section, the blackboard is in the cleaning section. Further, limit switches are provided at both ends of the guide rail, and the limit switches are electrically connected to the scrubbing part for limiting the range of movement of the scrubbing part.

[0062] The scrubbing part is slidably fitted on the guide rail device...

Abstract

The invention provides an automatic blackboard scrubbing device, and belongs to the field of teaching aids. The automatic blackboard scrubbing device comprises a guide rail device, a scrubbing part and a controller; and the guide rail device is arranged on the upper side and the lower side of the scrubbing part, the scrubbing part is movably arranged on the guide rail device, the controller is used for controlling the scrubbing part to move so as to control the scrubbing part to scrub a blackboard, and when the blackboard needs to be cleaned, only the controller needs to control the scrubbingpart to work, so that the problem that chalk dust is inhaled into a human body when the blackboard is manually cleaned is avoided. Therefore, the blackboard cleaning work can be efficiently and rapidly completed, and the chalk dust can be prevented from being inhaled into the body when the blackboard is cleaned.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to an automatic blackboard scrubbing device. Background technique [0002] The blackboard eraser is one of the most frequently used teaching aids in the teaching process. However, due to the lack of timely or thorough cleaning of the blackboard eraser, too much chalk dust will often accumulate on the blackboard eraser, making it less and less clean when teachers wipe the blackboard. The blackboard consumes a lot of time and reduces teaching efficiency. And when adopting manpower to wipe the blackboard, because a lot of chalk dust can be produced in the wiping process, these chalk dusts float in the air, are very easily sucked into the body by the teachers and students who are doing the work of wiping the blackboard, and the chalk dust sucks into the human body and easily causes trachea and The lungs are damaged, causing respiratory disease. Contents of the invention [0003] In orde...
