Multifunctional electronic board eraser

Technical field

The utility model relates to a multifunctional electronic board eraser, belonging to the core component of the intelligent electronic whiteboard blackboard system. Background technique

On a traditional whiteboard or blackboard, the teacher writes on the board with an ink pen or chalk, and wipes the useless handwriting with a dry or wet board.

There is a product called "Smart Scrubbing Blackboard" which only installs the remote control unit on the blackboard eraser and the black board. The scrubbing board on the remote control board moves up and down and left and right, and the water spray function is used to scrub the blackboard.

In order to promote the informatization of education, what is currently widely used is the so-called "sliding door combination type blackboard", in which a "flat-panel TV computer integrated machine" or "interactive whiteboard" is embedded in the middle position or side. Compared with traditional blackboards, the application of visual elements and whiteboard touch application software is an advancement towards educational informationization. However, it also leads to the protection of students' vision and the safety hazard when pushing and pulling the blackboard. More importantly, the push-pull blackboards on both sides can still only be written with a pen, erased with a squeegee, and there are no more functions.

Existing whiteboard blackboards focus on writing and scrubbing physical movements regardless of "dry rub", "wet rub" or "smart wipe". Some of them also integrate functions such as wireless microphones and laser pens in the eraser, and do not change the single erase function of the current eraser.

The modernization of education requires the teacher to teach the core and the students as the teaching center. Teachers and students interact to participate in classroom teaching to improve learning efficiency. The current various types of whiteboard blackboards, including electronic whiteboard blackboards, cannot meet the above requirements. Utility model content
