Problems solved by technology
[0003] Existing blackboards are mostly wiped manually with a blackboard eraser. When wiping, you need to press the blackboard eraser firmly to wipe, but the board surface is still not clean enough after wiping, and it is laborious
Even if there are some advanced blackboard wiping devices, the wiping effect is not ideal
After the blackboard has been used for a period of time, there are often residual traces of chalk on the blackboard surface. When writing again, double images often appear, which affects students' reading. It is easy for students in the last few rows of the classroom to read very hard.
[0004] On the other hand, during the process of wiping the blackboard, because the blackboard dust is scattered into the classroom, it is very easy to inhale into the lungs of the students, especially those who wipe the blackboard often need to cover their mouth and nose while wiping to prevent the inhalation of dust. Extremely inconvenient and comfortable
Moreover, the dust of chalk is scattered on the students' books and on the classroom floor, which is not easy to clean

Embodiment Construction
[0033] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.
[0034] Explanation: In this embodiment, the front side of the blackboard refers to the side where the blackboard faces the students when the multimedia teaching equipment is installed in front of the classroom; left and right refer to the side where the multimedia teaching equipment is installed in front of the classroom, and the lecturers and students face the side. Devices are left on their left hand side and right on their right hand side.
[0035] Figure 1-2 The three-dimensional structural diagrams of the blackboard according to the embodiment of the present invention are shown from different angles of view. like Figure 1 to Figure 2 As shown, the blackboard i...

The invention discloses an automatic blackboard wiping device, comprising an outer cover, a roller assembly and a swing motor, the swing motor is installed on the inner top wall of the outer cover, the roller assembly is rotatably supported on the inner bottom wall of the outer cover, and the swing motor The rotating shaft is connected with the roller assembly, which drives the roller assembly to swing as a whole. The outer cover is a cover-type structure with one side open, and the open side is used to face and fasten on the blackboard surface of the blackboard. Transitional arc surface structure. The automatic blackboard wiping device avoids the blurring of the blackboard due to long-term use, and the occurrence of double images when writing again, thereby enhancing the use effect of the blackboard. Moreover, the dust generated during the wiping process is absorbed by the outer cover and will not be scattered into the air, which greatly improves the user experience of lecturers and students, and is conducive to the improvement of teaching quality.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an automatic blackboard wiping device and a blackboard including the same. Background technique [0002] Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. Blackboards are mostly black, dark green, white or beige. [0003] Most of the existing blackboards are manually wiped with a blackboard eraser. When wiping, the blackboard eraser needs to be pressed firmly to wipe, but the board surface is still not clean enough after wiping, and it takes a lot of effort. Even if there are some advanced devices for wiping blackboards, the wiping effect is not ideal. After the blackboard has been used for a period of time, there are often residual traces of chalk on the blackboard surface. When writing again, double images often appear, which affects students' reading. It is easy for students in the last fe...
