Electronic blackboard with blackboard surface subjected to reciprocating wiping

Abstract

The invention provides an electronic blackboard with a blackboard surface subjected to reciprocating wiping. When a blackboard eraser is used for wiping the blackboard, a movement track of a conventional wiping method is abandoned; a similar movement track simulating the movement track of a front windshield wiper of an automobile is adopted, and the blackboard can be quickly wiped; and at the sametime, a magnet and an electromagnet are arranged in the blackboard eraser, so that the blackboard eraser can be in close contact with a blackboard body so as to achieve the best wiping effect, the blackboard body can be wiped through a water pump and a washing pump after a class is completed, and the wiping effect is good.

Description

technical field [0001] The invention belongs to the technical field of teaching tools, and in particular relates to an electronic blackboard capable of reciprocatingly wiping the board surface of the blackboard. Background technique [0002] In the traditional teaching mode, the blackboard is the main carrier for teachers to implement teaching. Teachers use chalk to write teaching content on the blackboard, and wipe the blackboard directly with a blackboard eraser after completing the explanation. On the one hand, this method will generate a lot of dust, which will float in the classroom, causing environmental pollution and affecting the health of teachers and students; on the other hand, long-term use will weaken the wiping effect and consume a lot of physical strength. Wiping during the classroom will also waste teaching time. With the development of science and technology, dust-free chalk, whiteboards, movable blackboards, and multimedia instruments have improved the clas...

Problems solved by technology

On the one hand, this method will generate a lot of dust, which will float in the classroom, causing environmental pollution and affecting the health of teachers and students; on the other hand, long-term use will weaken the wiping effect and consume a lot of physical strength. Wiping during the classroom will also waste teaching time

With the development of science and technology, dust-free chalk, whiteboards, movable blackboards, and multimedia instruments have improved the classroom teaching environment, but they still cannot replace the status of blackboard teaching. Creating an environmentally friendly and energy-saving wiping blackboard has certain research value. Therefore, The invention patent with the patent number CN103231604A discloses a blackboard with an automatic dust collecting eraser, which includes a blackboard body, horizontal slide rails are arranged on the upper and lower edges of the blackboard body, between the upper and lower horizontal slide rails An eraser device is arranged between them, and the eraser device includes an electric roller brush, a floating support mechanism and a dust cover set outside the electric roller brush, and the roller brush shaft is slidably connected to the On the upper and lower horizontal slide rails, the upper end of the roller brush shaft is provided with a geared motor, the dust cover is provided with a control handle, and the control handle is provided with a control switch

The lower end of the dust-proof cover is also provided with a dust collection box, the lower end of the roller brush shaft is provided with a dust suction blade, and the lower end of the dust collection box is provided with a dust collection bag. This invention is an electric roller brush for erasing blackboard , has the advantages of labor-saving, time-saving and automatic dust collection, but the present invention also has many disadvantages in actual use: first, when the blackboard eraser wipes the blackboard, it not only needs to move left and right but also needs to move up and down, and the wiping speed is relatively slow; Second, the contact between the blackboard eraser and the blackboard is not close enough, and the dust collection effect is not good
