The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, there is provided a kind of structure design
The novel dustless blackboard suitable for English Major teaching that is novel, being easily achieved.
In order to realize the purpose of this utility model, the technical scheme that the utility model is used for：
Design a kind of novel dustless blackboard suitable for English Major teaching, it include for write font plate body,
For the housing that the plate body is fixedly installed；The housing includes back plate, is arranged at the back plate setting of the protrusion of back plate surrounding
Extension board, the plate body is stuck in four extension boards of back plate surrounding, and interval is provided between the plate body and the back plate；
The top and bottom of the plate body are respectively arranged with several air suction openings, air suction opening being arranged at the top and bottom of the plate body etc.
Transversely arranged setting is spaced, two suction tubes of horizontally set, position are provided with the interval between the plate body and the back plate
Each air suction opening at the top of plate body is connected by conduit with suction tube above；Each air suction opening positioned at plate body bottom also leads to
Conduit is crossed to be connected with underlying suction tube；Also include the another of the manifold trunk that is connected with two suction tubes of one end and manifold trunk
The negative pressure pump of one end connection, the sack cleaner for also being connected including the gas outlet with the negative pressure pump；At the top of the plate body
With the curved dust-leading board of end face is additionally provided with the extension board of bottom.
U-shaped draw-in groove is respectively arranged with four madial walls of extension board of the housing surrounding, the plate body surrounding
End is located in the U-shaped draw-in groove on corresponding extension board respectively.
The top both sides of the plate body are connected by crash roll with the inwall of the U-shaped draw-in groove respectively.
The crash roll is flexible rubber pad.
Several are additionally provided with the inner surface of each dust-leading board for the LED lamp bead to plate body irradiation light.
The beneficial effects of the utility model are：
The blackboard of the design in the application first can by because writing when or produced dust is siphoned away during erasing, it is to avoid its
Drop and cause Environment pollution and the phenomenon of infringement health of human body to occur indoors, secondly, the negative pressure pump of the design may be disposed at room
Normal education activities are not influenceed outward；Furthermore, can be collected for dust by the use of sack cleaner by the design, be easy to
Reclaim, it also avoid the risk of secondary pollution；And the design by the use of crash roll can by because suction tube works when produced
Raw vibrations are eliminated, it is to avoid the problem shaken caused by its suction tube is to plate body occurs.
