Problems solved by technology

[0002] As far as the currently widely used chalk writing blackboard teaching aids are concerned, there is an obvious problem that chalk dust is difficult to deal with, that is, the current dust-free blackboard and dust-free blackboard eraser combination teaching aids rely on manual cleaning of the chalk writing after writing, which is inevitable. During the manual cleaning process, a large amount of floating dust is generated, which has caused great harm to the health of the trachea and skin of the majority of teachers and students, and at the same time brought difficulties to the maintenance of the indoor teaching environment and other media teaching equipment
So far, there is still a lack of perfect automatic blackboard dust cleaning technology to solve this kind of problem, and related technologies still need to be further developed

Embodiment 1

[0026] Such as Figure 1-3 As shown, an electric dust-free erasing type blackboard includes: a transmission type blackboard surface mechanism 1, a wet dust removal mechanism 2 and a surface air drying mechanism 3, and the wet dust removal mechanism 2 and the surface air drying mechanism 3 are respectively It is located at both ends of the transmission type blackboard panel mechanism 1. It can be seen that the electric dust-free erasing type blackboard of the present invention is mainly composed of three areas, the first area is the writing area, that is, the transmission type blackboard surface mechanism 1, and the second area is the erasing area, that is, the wet dust removal mechanism 2. The third area is the drying area, that is, the surface air drying mechanism 3. These three areas are organically combined and closely matched to form the entire closed frame of dust removal, which ensures that the entire dust removal process is carried out in this space without spreading t...

Embodiment 2

[0040] Such as Figure 1-3 As shown, on the basis of embodiment 1, further improvement is carried out. In embodiment 2, a water pump (not shown in the figure) is set in the wet dust removal mechanism, and the water pump connects the outlet pipe 24 through the connecting pipeline. It communicates with the water inlet pipe 25 and is used to realize the auxiliary water circulation and wet the filter system.

[0041] At the same time, in order to achieve the purpose of automatically opening the water pump, the present invention is provided with a sensor (not shown) for detecting the rotation of the transmission shaft on the transmission shaft 14. At this time, the water pump starts to work, realizes the recycling of filtered water, and achieves continuous wetting of the engineering sponge, ensuring the continuous and reliable operation of the wet dust removal mechanism.

Embodiment 3

[0043] Such as Figure 4 As shown, as an improvement of embodiments 1 and 2, what this embodiment 3 shows is the internal frame of the flexible blackboard panel 11, including: several panel support steel frames 17 arranged parallel to the transmission shaft 14 and connecting panel supports The steel frame 17 also has a board support piece 18 that supports the blackboard board 11.

[0044] The blackboard surface of this embodiment not only has the characteristics of simple structure and light weight, but also can ensure the smooth operation of the flexible blackboard surface.

[0045] The main problem solved by the present invention is to automatically clean and erase the used blackboard, so that the process of cleaning chalk dust is clean, environmentally friendly, efficient and pollution-free, and the purpose of dissolving chalk dust in water is realized, thereby creating a good educational environment. The invention has a simple structure, does not delay teaching time durin...

Abstract

The invention relates to an electric dust-free erasing-type blackboard comprising a transmission-type blackboard surface mechanism and a wet dedusting mechanism. The transmission-type blackboard surface mechanism comprises a flexible blackboard surface, a transmission device and a power device connected with the transmission device. The wet dedusting mechanism comprises a water storage device with the end being sealed and an erasing unit, wherein a plurality of water outlet holes are formed in the side wall of the water storage device, and the surface of the erasing unit makes contact with the blackboard surface in a squeezing mode and is closely attached to the water outlet holes of the water storage device. The structural form that the surface of the erasing unit makes contact with the flexible blackboard surface in a squeezing mode is adopted to achieve relative movement between the flexible blackboard surface and the erasing unit; the erasing unit is closely attached to the water outlet holes so that the erasing unit can absorb water intermittently in the contact squeezing process, dust on the board surface are dissolved and taken away through water flows, and accordingly automatic cleaning, environmental-friendly, efficient and pollution-free board surface erasing is achieved.

Description

technical field [0001] The invention relates to a blackboard teaching aid for teaching, in particular to an electric dust-free erasable blackboard, in particular to an environment-friendly blackboard which uses water flow to dissolve dust. Background technique [0002] As far as the currently widely used chalk writing blackboard teaching aids are concerned, there is an obvious problem that chalk dust is difficult to deal with, that is, the current dust-free blackboard and dust-free blackboard eraser combination teaching aids rely on manual cleaning of the chalk writing after writing, which is inevitable. During the manual cleaning process, a large amount of floating dust is generated, which has caused great damage to the trachea and skin health of the teachers and students, and at the same time brought difficulties to the maintenance of the indoor teaching environment and other media teaching equipment. So far, there is still a lack of relatively complete technology for auto...
