Dynamic connection, is equipped with electrostatic attraction electrode scraper plate between the round brush and the board wiper box and the electrostatic attraction electrode scraper plate is fixed on the plate
Cassette bottom portion is wiped, battery is equipped in the board wiper box, the battery is equipped with contact conductor to the electrostatic attraction electrode scraper plate, the blackboard eraser
The two sidewalls that box is located at the round brush radial direction are equipped with rubber strip sticky position, and the round brush rubs with rubber strip during rotation
It wipes, the board wiper box lower end is detachably equipped with dust box, and the board wiper box is equipped with dust passage and is connected to the dust box.It should
Utility model is good by the reusable effect of electrostatic precipitation but structure is complicated, at high cost.
Through retrieving, China Patent No. CN201420813353.9, patent filing date is on December 18th, 2014, practical new
Type is created entitled：Dustless eraser, this application discloses a kind of offer Dustless eraser, including blackboard eraser main body, the blackboard eraser master
The lower part of body is provided with dust catcher；The rear portion of the blackboard eraser main body is provided with dust box；The side of the dust catcher is provided with suction
Dirt mouth；The dust catcher is internally provided with motor.The utility model can effectively remove the floating materials such as chalk dust removing but structure is multiple
It is miscellaneous at high cost.
Summary of the invention
Present invention is primarily aimed at provide the teaching aid of a Dustless eraser for wiping blackboard.Water passes through water filling
Mouth enters the reservoir bed of Dustless eraser, then controls water yield by extruding dynamics by the extruding discharging device on rubber water storage bag
To reach the optimum state of blackboard eraser software wiping blackboard.The Dustless eraser structure is simple, and using effect is good, is convenient for practical application.
To achieve the goals above, the present invention adopts the following technical scheme that：A kind of Dustless eraser, including：Blackboard eraser shell is inhaled
Water sponge, squeezes water outlet, water storage bag at water filling port, wherein blackboard eraser shell, water storage bag and water-absorbing sponge are fixedly connected with, plate
It wipes shell and opens water filling port, water filling port one end is tightly connected equipped with the sealing cover other end and water storage bag；It is squeezed on water storage bag with several
The mouth of a river is extruded, the round rubber circle that the extruding water outlet is cracked by center forms；It is squeezed out by squeezing strength control
The size that mouth of a river center is cracked reaches the dampness control of blackboard eraser software.
The further water storage bag is rubber material.
Further several extruding water outlets are evenly arranged on water storage bag.
Further sealing cover and water filling port screw thread are screwed on.
The further rubber ring is circle, is made of multiple fan-shaped surfaces interconnected, rubber ring center is opened
Seam.
Beneficial effect of the present invention：The present invention provides a kind of teaching aid of Dustless eraser.It is controlled and is discharged by strength
The water yield size of device reaches the dampness of blackboard eraser software, and the apparatus structure is simple, easy to use, practical, is suitable for institute
There is the wiping of blackboard and blank, is suitable for various kinds of schools and training organization.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is that the present invention squeezes water outlet normal condition enlarged diagram；
Fig. 3 is that the present invention squeezes water outlet squeezed state enlarged diagram；
Wherein：1, blackboard eraser shell；2, water-absorbing sponge；3, water filling port；4, blackboard eraser reservoir bed；5, water outlet is squeezed；6, water storage bag.
Specific embodiment
It further illustrates with reference to the accompanying drawing：A kind of Dustless eraser, blackboard eraser shell 1, water storage bag 6 and water-absorbing sponge 2 are fixed
It connects, blackboard eraser shell opens water filling port 3, and water filling port one end is tightly connected equipped with the sealing cover other end and water storage bag 6, intermediate shape
At blackboard eraser reservoir bed 4；With 4-8 evenly distributed extruding water outlets on water storage bag, the extruding water outlet is by multiple mutual
The round rubber circle composition that the fan-shaped surface of connection and center are cracked, water storage bag are rubber material, sealing cover and the rotation of water filling port screw thread
It connects.
The innovation of the invention consists in that squeeze the design of water outlet, squeeze water outlet by multiple fan-shaped surfaces interconnected and
The round rubber circle composition that center is cracked, when blackboard eraser is placed, no external force is squeezed, and is squeezed discharging device and is in " normal " state such as
Shown in Fig. 2, the flexible mutual extrusion of rubber ring itself, gap is closed, and water will not flow out；When firmly squeezing, discharging device is in
As shown in figure 3, rubber ring is deformed, center slot increases " squeezing water outlet " state, and water can flow out；By squeezing great efforts
Small control squeeze the size cracked of water outlet center reach control squeeze water outlet number soak automatically, realization dust-free cleaning.Into
After the sealing of the mouth of a river, blackboard eraser reservoir bed 4 maintains water state, when extruding water outlet is not extruded, squeezes water outlet and is not discharged, inhale
Water sponge is in drying, and when extruding water outlet is extruded, water outlet water outlet, water-absorbing sponge soaks or be in dampness, this
When wipe blackboard, fully achieve dust-free cleaning.
Embodiment 1：The sealing cover of rotation water filling port counterclockwise, sealing cover is opened, and is directed at tap water or water is poured into it
In, guarantee that water is not spilt over, fill the water 1/3 under normal circumstances, use lighter, filled the water again when water is inadequate,
Sealing cover is rotated clockwise into make-up after water injection, guarantees that water does not flow out.Blackboard eraser software can be placed downward before, first slightly be used
Power squeezes to be discharged so that squeezing water outlet, and water-absorbing sponge is uniformly soaked, blackboard at this moment can be normally wiped with Dustless eraser, is realized
Dust-free cleaning.
Embodiment 2：The sealing cover of rotation Dustless eraser water filling port counterclockwise, the water in blackboard eraser reservoir bed is all poured out,
Sealing cover is tightened clockwise again, directly wipes the writing space of a whole page of blank, as conventional money blackboard eraser use, without any area
Not.
