A blackboard cleaning structure

Abstract

The invention discloses a blackboard cleaning structure, comprising a casing, a first accommodating cavity and a second accommodating cavity are formed in the middle part of the casing by a transverse plate, wherein a driving module is installed in the first accommodating cavity, and the main shaft of the driving module is The horizontal plate penetrates vertically downward, a rotating shaft is connected to the lower end of the main shaft, an adsorption assembly is connected to the lower end of the rotating shaft, and a painting assembly is arranged at the lower part of the adsorption assembly. In the arrangement of the blackboard cleaning structure of the present invention, the driving motor in the driving module works to drive the adsorption assembly and the painting assembly to rotate synchronously, and the second solid part of the painting assembly drives the brush to contact the blackboard surface first, and the water in the spline hole passes through the water outlet to the surface of the blackboard. External spray to clean the raised chalk marks on the blackboard surface, the adsorption component moves down, the sponge block at the lower end of the solid part on the adsorption component contacts the blackboard surface, and the chalk marks on the blackboard surface are removed, this blackboard cleaning structure realizes It has the effect of high efficiency, energy saving and better cleanliness.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a blackboard cleaning structure. Background technique [0002] Although along with the development of science and technology, the application of multimedia teaching aids is more and more extensive, it still cannot replace the traditional teaching method of writing and teaching with chalk. And in daily teaching work, adopting chalk to write can cause the generation of dust, also can still cause dust to fly everywhere when using chalk to wipe blackboard, thereby brings huge impact to the health of teaching staff etc. In order to solve the problem of dust flying everywhere, dust-free chalk has been popularized. The main components of this type of chalk are titanium dioxide and vegetable oil. Although the dust-free chalk solves the problem of flying dust, it also has defects, such as poor water solubility, difficult to wipe with general blackboard erasers, and poor class expe...

Problems solved by technology

Although the dust-free chalk solves the problem of flying dust, it also has defects, such as poor water solubility, general blackboard erasers are difficult to wipe, and the problem of poor class experience

[0003] In the prior art, although some blackboard cleaning devices or equipment have appeared to solve the problem of being difficult to wipe, they are either too large in size or complicated in operation, resulting in poor portability, difficult installation, and difficulty in popularization, especially in some For example, in environments such as universities, there are no fixed classrooms, and classrooms need to be constantly changed to attend classes.

If each classroom is equipped with complex cleaning devices or the cost of equipment is too high, it is easy to cause waste of resources, and the cost of teacher training is also high

If you carry it with you every time you go to class, it will bring great inconvenience
