Description
Technical field
The invention belongs to teaching aid, blackboard structure technical field, more particularly to equipped with the multi-functional of side dust-collecting mechanism
Blackboard.
Background technology
Present blackboard structure is single, and dust diffuses, and many teaching aid equipments will also subsequently be built so that metope is miscellaneous
Disorderly, the chaotic layout of various teaching aids is unreasonable, without a kind of dust-free blackboard for integrating a variety of teaching aid functions.
Such as a kind of multi-functional blackboards of number of patent application CN201510606068.9, it includes being fixed by the bracket in wall
On blackboard and the projector mechanism and Wiping mechanism of blackboard on both sides are arranged on by suspension arrangement respectively；The present invention substantially has three
A part is formed, and steel plate layer is set and can be carried out when LED light matrix is uniformly distributed use according to the luminous point that glass writing layer is shown
Positioning, it is possible to reduce the use of ruler set square, improves writing on the blackboard efficiency, and the light of LED light is write by the glass of hair side
The display effect of black and white is not influenced after layer, the dustless module and the folding and unfolding module of projection screen also to erase the board, good integrity collection is more
Kind function is.
Based on above-mentioned, the inventors discovered that, existing blackboard and and above-mentioned patent in blackboard in use for dust
The all unused more improvement of aspect, although both knowing about the harm of dust, does not carry out effective measure, using wiping
The mode wiped, it is difficult to avoid dust from diffusing.
And as a kind of multi-functional blackboard in application number CN201620304399.7, multi-functional blackboard include multi-functional blackboard sheet
Body, is provided with display screen component on the multi-functional blackboard body, lighting device, institute is provided with above the display screen component
State and accommodating groove be provided with below multi-functional blackboard body, the display screen component include the first display screen, second display screen and
3rd display screen, wherein second display screen are arranged among the first display screen and the 3rd display screen, between three display screens mutually
Mobile, the lighting device includes lampshade and LED light, and the lampshade is arranged on the top of LED light.First in the technical solution
USB interface is both provided with display screen, second display screen and the 3rd display screen, USB jack is the input interface of display screen,
For inputting display content, it can show image and word；3) technical solution can also be straight on the surface of display screen
Connect and write letter written with chalk, the blackboard so to combine, uses very flexibly, conveniently.
When different from the blackboard in first patent, the blackboard in above-mentioned patent is more first to solve dust problem use
Into compounded times trend multimedia mode, but the teaching in many reality is given lessons, and is only given lessons excessively with multimedia mode
It is mechanical, it is impossible to realize the real time education for formula of adjusting to changed conditions.
Then, in view of this, improvement is studied for existing structure and missing, there is provided equipped with side dust-collecting mechanism
Multi-functional blackboard, to achieve the purpose that with more more practical value.
The content of the invention
It is existing to solve in order to solve the above technical problem, the present invention provides the multi-functional blackboard equipped with side dust-collecting mechanism
There is teaching aid confusion to be laid out unreasonable, dust, which diffuses, to be difficult to quickly be solved, and multimedia technology can not substitute tradition completely
