The advantages of platform is explained and publicised in the utility model intelligence classroom is that this is explained and publicised platform and can be stored with microphone and microphone stand,
And dais is risen from according to human body sensing, protected with microphone and microphone stand, meanwhile, this, which explains and publicises platform, also has air filtration work(
Can, indoor air quality can be improved to teaching indoor air-borne dust to carry out effective filtration, purification.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the structure diagram that platform is explained and publicised in the utility model intelligence classroom.
Fig. 2 is the structure diagram that platform filtration core is explained and publicised in the utility model intelligence classroom.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making the creative labor
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in drawings, platform, including dais main body 1 are explained and publicised in the utility model intelligence classroom, and at dais, 1 lower part of main body is set
There is base 2,1 top of main body is provided with table top 3 at dais, and LED light strip 14 is provided with table top 3.LED light strip 14 can be improved and said
