Abstract

The invention discloses a dust-proof electric blackboard eraser based on a smart classroom and a control system of the dust-proof electric blackboard eraser, and relates to the technical field of dust-proof electric blackboard erasers. The dust-proof electric blackboard eraser based on the smart classroom comprises a protective outer cylinder, a rotary inner pipe, a mounting cylinder and a rotarypowder suction device, wherein the rotary powder suction device comprises a servo motor, an electric telescopic rod, a plurality of rotating rods and a plurality of rotating plates. When a plurality of sponge wiping strips are extruded to the side face of a blackboard by pressing the mounting cylinder, a pressure sensor detects and transmits a pressure signal to a main controller, the main controller controls the servo motor to rotate so as to drive the sponge wiping strips to rotate to wipe chalk marks on the blackboard, wiped-off chalk powder is attracted by static electricity on first conductive cloth and second conductive cloth, dust diffusion is avoided, dust adsorption is facilitated, and the blackboard eraser is convenient to use and practical. After wiping is completed, the controller controls the electric telescopic rod to do telescopic motion, then annular scraper blades and fan-shaped scraper blades are controlled to scrape out dust on the side faces of the first conductivecloth and the second conductive cloth, and repeated use is facilitated.

Description

technical field [0001] The invention belongs to the technical field of dust-proof electric blackboard eraser, in particular to a dust-proof electric blackboard eraser for smart classrooms and a control system thereof. Background technique [0002] With the rapid development of Internet of Things technology, smart devices in the teaching field are becoming more and more convenient for teachers and students to interact with each other. Various smart devices in smart classrooms are popular, such as smart electronic blackboards, projectors, and multimedia consoles. [0003] Although the current intelligent teaching equipment can greatly improve the teaching efficiency and quality; however, it is inevitable to use traditional chalk for writing and display. After writing with chalk, it needs to be wiped with a blackboard eraser; however, a large amount of chalk powder will be produced during the wiping process, which will cause teachers and students to absorb a lot of chalk powde...
