Description

Technical Field

[0001] The utility model relates to the technical field of multifunctional blackboards, and in particular to a multifunctional smart blackboard that is convenient for teachers of different subjects to teach. Background Art

[0002] A blackboard does not specifically refer to a black board. In the traditional sense, it is a flat surface that can be written on repeatedly. The board is hard and is mostly used for teaching. It is mostly black, dark green, or white. In order to meet the needs, the types and functions of blackboards are now more abundant. The existing blackboard can meet the needs of writing education, but the blackboard needs to be wiped manually after each writing. A lot of dust will be generated in the process of erasing the blackboard, which affects human health. In addition, manual wiping of the blackboard is not clean enough and will waste a lot of time.

[0003] Chinese patent document CN215552199U discloses a multifunctional blackboard for smart education, including a height adjustment bracket, a base plate, the bottom of the base plate is fixedly connected to the top of the height adjustment bracket, the top of the base plate is fixedly connected to a blackboard frame, the inner side of the blackboard frame is fixedly connected to a writing blackboard, and a self-cleaning component, the back of the self-cleaning component is slidably connected to the front of the blackboard frame. The above-mentioned multifunctional blackboard for smart education has shortcomings. Although the device can automatically wipe the blackboard, it has limitations. The device uses a cleaning cotton wipe for dry wiping and wet wiping, and the dust on the cleaning cotton wipe is difficult to clean. Therefore, when the cleaning cotton wipe is wet with water, the water and dust are mixed. After the cleaning cotton wipe is wet, a large amount of stains will remain on the blackboard, which increases the difficulty of cleaning the blackboard and is inconvenient to use.

[0004] Therefore, in order to solve such problems, we proposed a multifunctional smart blackboard that is convenient for teachers of different subjects to teach. Utility Model Content
