The teaching process by using the teaching system of the embodiment is as follows:
step one, writing is normally carried out on the double-layer single-color board surface 101, when no available space exists, one side for writing on the double-layer double-color board surface 102 is written, when the space is not enough, a button of a rotating motor 105 is pressed, the board surface of the double-layer single-color board surface 101 is rotated, and writing is carried out on the other side; when the cleaning motor 209 is not started during rotation, the previously full blackboard surface cannot be cleaned, and the blackboard surface can be rotated back again for using the contents on the blackboard surface;
step two, writing on the double-layer single-color board 101 normally, when the blackboard needs to be used continuously and the written blackboard writing does not need to be reserved previously, pressing the buttons of the rotating motor 105 and the dust removing motor 209, simultaneously changing the clean side and cleaning the board on the side far away from the user, and then writing on the clean board continuously;
step three, when a student cannot see the blackboard clearly due to turning off, the user can press a button of the rotating motor 105 to rotate the board surface of the double-layer single-color board surface 101, so that the handwriting at the previous reflecting position is moved to the non-reflecting position, and the student can see the handwriting which is not seen before;
step four, when the pace of class attendance is fast, the blackboard writing students cannot remember too soon, turn on the switch of the scanner 301, continue to attend class normally like the step two describes, use and clear up the blackboard normally; the scanner 301 sends the scanned image to the projection console 304, and after the image is processed by the projection console 304, the user can select to project the processed image onto one surface of the double-layer double-color board 102 for projection through the projector 302, or send the processed image to students in class;
step five, after the dust collecting box is used for a period of time, a user only needs to inject dust collecting liquid into the liquid box 210 from the water injection port 211 and then draws out the dust collecting net 219 in the dust collecting box 217 for flushing and cleaning, and then the dust collecting box can be used continuously;
step six, when articles need to be taken and placed, the handle 412 is pulled downwards to pull the storage box 401 and the sliding component attached to the storage box down, due to the magnet 413, the bottom of the storage box 401 is attached to the wall surface, the top of the storage box points to a user, and the user can take and place the articles from the top; after the storage is finished, the user only needs to clap the upper part of the storage box 401 to enable the storage box 401 to return to the plane parallel to the sliding component, and the storage box 401 returns to the inner part of the plate lining 108 under the pulling of the main spring 406;
and step seven, when the articles need to be accessed, on the basis of the step four, the movable slot closing sheet 410 needs to be moved away from the lattice 414, and after the articles are accessed, the movable slot closing sheet 410 is moved back to the lattice 414 to abut against the articles.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
