Novel environment-friendly dust-free blackboard

Abstract

The invention discloses a novel environment-friendly dust-free blackboard, and belongs to the technical field of blackboards. The novel environment-friendly dust-free blackboard comprises a blackboardboard surface, vertical moving devices are fixedly connected to the symmetric positions at two sides of the blackboard board surface, a collecting tank is fixedly connected to the sides, next to eachother, of the vertical moving device and is located right under the blackboard board surface; and a cleaning device is slidably connected to the sides, next to each other, of the vertical moving device and is located at the position on the front surface of the blackboard board surface, a spraying and drying device is fixedly connected to the top of the cleaning device, and a shielding blocking plate is fixedly connected to the top of the blackboard board surface. According to the novel environment-friendly dust-free blackboard, water flow and a cleaning eraser are used for scrubbing the boardsurface, dust is prevented from flying and floating, the environmental security is protected, the board surface is subjected to rapidly drying through hot wind,the situation that the board surface can be rapidly used is ensured, the lesson effect is ensured, so that the personal security and learning progress of students are ensured.

Description

technical field [0001] The invention relates to the technical field of blackboards, in particular to a novel environment-friendly and dust-free blackboard. Background technique [0002] The blackboard is one of the necessary tools in the classroom, and the blackboard that can record the teacher's handwriting in class has always been the focus of our attention. Blackboards have been painted on the surface of hard objects such as wood boards and cement with black paint at the earliest, to ground glass in the 1990s, and now to color-coated steel plates and composite material plates. The times are advancing, and the types of blackboards have become more complex and diverse. If classified in detail, there are more than ten types of blackboards existing in the market. From so many blackboards, it is not a simple matter to choose the blackboard that suits the student's situation. At present, the known blackboard has a limited use area, and it must be erased when it is full of wo...
