Embodiment
As shown in figure 1, mainly by portions such as casing 1, inflator 2, absorption chamber 11, check valve, water filling port 6, delivery port 8, supporting legs 9
It is grouped into, the casing 1 of sealing is supported by supporting leg 9, and the internal memory of casing 1 contains dust suction liquid, can use clear water 10, the bottom of casing 1
Provided with delivery port 8, for discharging the internal liquid dissolved with chalk dust, the bottom surface of casing 1 is preferably in the funnel structure to lower recess, this
Sample is easy to chalk dust to concentrate discharge, and delivery port 8 is provided with flowing water Valve 7, can control opportunity of the discharge dissolved with chalk dust liquid,
Casing 1 is transparent cabinet 1, is so easy to observe and dissolves in whether chalk dust is excessive, and convenience is cleared up in time, the side of casing 1 in liquid
It is convenient to inject dust suction liquid or top is provided with water filling port 6.
Casing 1 is provided with the absorption chamber 11 for being used for placing blackboard eraser 19, and blackboard eraser 19 is placed in the bothrium 14 in absorption chamber 11,
The bottom land hole 15 that is uniformly distributed of the bottom of bothrium 14 helps uniformly for negative pressure to be distributed in the bottom of blackboard eraser 19, improves and absorbs chalk
Grey efficiency, the bottom of absorption chamber 11 are provided with a through hole, and the chalk dust dropped into by bothrium 14 in absorption chamber 11 can be arranged from through hole
Go out, the open top of absorption chamber 11 is simultaneously provided with lid 5, is open for being put into blackboard eraser 19, lid 5 is used to seal, and ensures absorption chamber
It is in a relatively closed space in 11.
Lid 5 is provided with depression bar 4, and return spring is provided between depression bar 4 and lid 5, and depression bar 4 is extend into one in absorption chamber 11
End is provided with the slap plate for being used for patting blackboard eraser 19, when so blackboard eraser 19 is put into bothrium 14, can utilize pressing pressure
Bar 4 makes slap plate impact blackboard eraser 19, allows on blackboard eraser 19 chalk dust gathered is as much as possible to drop into the bottom of absorption chamber 11.
In order to improve the dedusting effect of slap plate, lead 17 is vertically fixed in absorption chamber 11, lead 17 is by two
The hollow column being mutually socketed is formed, and a column is fixed on the bottom of absorption chamber 11, and another column is fixed on bothrium 14
Bottom surface, support spring is provided between bothrium 14 and the bottom surface of absorption chamber 11, support spring is preferably disposed in lead 17, so can be with
Bothrium 14 is allowed with slap plate vibrations, in addition, the outer wall of bothrium 14 is provided with the cooperation of the inwall gap of absorption chamber 11, the inwall of bothrium 14
