It is unable to do without the application of multimedia presentation technology.The change of teaching method has driven the production of teaching instrument and equipment and application to change
Become, with the expansion of information content, the shortcomings that textbook information content is insufficient can be supplied using multi-media platform in teaching.Multimedia is said
It is that a kind of regard at dais with computer, multi-media control system, video presenter, audio frequency apparatus, sound is converted that platform, which is also known as Electronic platform,
The product that the electronic products collection such as device is integrated.
Multi-media platform used in traditional multimedia presentation classroom, typically from a multi-purpose structure cloth
Office, teacher is carried out class hour in multimedia presentation mode using multimedia equipment, very convenient.But multi-media platform is in reality
There are configuration is chaotic in the application of border, chaotic configuration, in some component inconvenient maintenance problem when something goes wrong, with
And multimedia volume is big, heavy and the problems such as be inconvenient to move.Most importantly most multi-media platform desktop is exposed,
Computer equipment etc. easily dust stratification so as to influencing function.Particularly computer, it is anti-that substantial amounts of dust stratification so that stuck and dust stratification occurs in computer
The problems such as slow is answered, the teaching process of teacher can be influenced.
Existing Chinese patent notification number is a kind of " CN105411177A " multi-media platform with dust cover, including main body
Case and table top, the inverted U-shaped structure that the cross section of the table top is integrally formed, table top include the desktop being located on main body case and position
Backplate in desktop both sides, longitudinal isometry position is both provided with slide on two pieces of backplates, and protective cover, table are connected with by two slides
Face is provided with microphone and computer screen, and microphone is set on the table by articulated form, is both provided on three edges of desktop
Dismountable baffle is provided with blue-tooth device on desktop, and main body lower box part is provided with shifting roller.The program can with dust cover
It can only be carried out when dais use finishes dust-proof, but dust cover cannot be handled the dust of accumulation, can not be to main box
It carries out dust-proof.
The content of the invention
It is an object of the invention to provide a kind of Multifunctional multimedia dais, excessively influence to use to solve dais dust
The problem of.
In order to achieve the above objectives, the technical scheme is that：A kind of Multifunctional multimedia dais including main box and is said
Platform, dais are fixedly installed in above main box, and dais is fixed with baffle, and dais is equipped with one inner cavity of formation when being closed with shutter

Row is drained and discharged outward.
Beneficial effects of the present invention：(1) present invention is reasonably arranged the power cord of main tank in-vivo device by truss
Cloth facilitates maintenance personal to carry out the detection of power supply, and prevents power cord distribution at random, and power cord is avoided to damage.Truss can be with
Dust is blocked, can be dust-proof to power cord progress, and the gas of air amplifier discharge is drained.
(2) by the cooperation of air pressurizing unit and high-pressure gas box, sucking dedusting is carried out to dais, ensure dais using when do not have
There is dust.
(3) when closing dais every time, dust can all be handled, it is possible to reduce the accumulation of dust avoids computer because of ash
Dirt accumulation reduces the work efficiency of multimedia equipment.So that it improves the quality of teaching.
On more than base case：
Preferred embodiment one：The grain frame is equipped with to adsorb the wash water cotton of dust.It is directed toward slot in the outlet of air amplifier
Frame, and it is passed through to truss the dust gas of collection.Dust gas blows on wash water cotton and can be adsorbed, to being adsorbed with the suction of dust
Water cotton is focused on, convenient and efficient.
Preferred embodiment two：Network interface is fixed with below the major trough frame.For network interface for being inserted into cable, being placed in main box can
Protection network joint enters dust and influences to use, while is also convenient for carrying out winding displacement.
Preferred embodiment three：The multifunctional power socket is equipped with dust cover.Dust is avoided to enter in multi-function jack to lead
Cause line short.
Preferred embodiment four：The cover is equipped with air admission hole.When air amplifier carries out air-breathing to inner cavity, by the external world
Air sucking carries out flowing and facilitates the dust handled in inner cavity, while cover is avoided to be deformed due to inner cavity forms negative pressure.
