Description

Technical Field

[0001] The utility model relates to the technical field of writing whiteboards, and more particularly to an intelligent writing whiteboard. Background Art

[0002] Traditional electric whiteboards use a composite film as the writing surface. The film is rolled, coiled, or wrapped around rollers driven by a motor. When the screen is full, a switch is pressed, and the motor drives the rollers to reel in the film or roll it back, bringing out another clean, blank sheet of film for continued writing. This provides great convenience for the writer. However, this electric whiteboard also has significant drawbacks. Once the writing surface is full, the content must be manually erased with a brush, just like cleaning a traditional blackboard. This is time-consuming and laborious. Frequent wiping of the whiteboard not only interrupts the teacher's lecture flow but also easily distracts inattentive students.

[0003] The Chinese utility model disclosed in the prior art with publication number CN2291310Y is an electrically erasable writing whiteboard. The content left by the whiteboard pen on the writing screen can be completely and cleanly erased through the friction generated by the pressing of the erasing post and the composite film, and the relative movement of the erasing post and the composite film driven by the motor. When the content on the writing screen is to be retained, the erasing post and the motor are not powered, and the erasing post is passively rotated by the friction of the composite film. In this way, the erasing post and the composite film have the same linear speed, and there is no relative movement between them, so the content on the writing screen will not be erased; however, when the content on the writing screen needs to be retained, although the composite film is not subjected to the friction of the relative movement of the erasing post, when rotating in the same direction, the movement of the composite film will still cause a certain friction between it and the erasing post, which makes it difficult to completely retain the content on the writing screen, and the motor needs to be repeatedly turned on and off according to needs, so that it is powered on and off, which is extremely inconvenient. Therefore, the present application proposes an intelligent writing whiteboard. Utility Model Content
