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 creates title are as follows: Dustless eraser, this application discloses a kind of offer Dustless eraser, including blackboard eraser main body, and 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
The utility model main purpose is to provide the teaching aid of a Dustless eraser for wiping blackboard.Water passes through
Water filling port enters the reservoir bed of Dustless eraser, then is controlled out by the extruding discharging device on rubber water storage bag by extruding dynamics
Water come reach blackboard eraser software wiping blackboard optimum state.The Dustless eraser structure is simple, and using effect is good, convenient for actually answering
With.
To achieve the goals above, the utility model adopts the following technical solution: a kind of Dustless eraser, comprising: outside blackboard eraser
Shell, water filling port, squeezes water outlet, water storage bag at water-absorbing sponge, wherein blackboard eraser shell, water storage bag are fixedly connected with one with water-absorbing sponge
It rises, blackboard eraser shell opens water filling port, and water filling port one end is tightly connected equipped with the sealing cover other end and water storage bag；If having on water storage bag
Dry to squeeze water outlet, the round rubber circle that the extruding water outlet is cracked by center forms.
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.
The utility model is the utility model has the advantages that the utility model provides a kind of teaching aid of Dustless eraser.Pass through strength
The water yield size of control discharging device reaches the dampness of blackboard eraser software, and the apparatus structure is simple, easy to use, practical,

Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is that the utility model squeezes water outlet normal condition enlarged diagram；
Fig. 3 is that the utility model 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
Further illustrate 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 innovative point of the utility model is the design of extruding water outlet, squeezes water outlet by multiple sectors interconnected
The round rubber circle composition that face and center are cracked, when blackboard eraser is placed, no external force is squeezed, and is squeezed discharging device and is in " normal " shape
State is as shown in Fig. 2, the flexible mutual extrusion of rubber ring itself, gap closure, water will not flow out；The discharging device when firmly squeezing
In " squeezing water outlet " state as shown in figure 3, rubber ring is deformed, center slot increases, and water can flow out；According to squeezing out
Water number soak automatically, realize dust-free cleaning.After inlet seal, blackboard eraser reservoir bed 4 maintains water state, is discharged when squeezing
It when mouth is not extruded, squeezes water outlet and is not discharged, water-absorbing sponge is in drying, and when extruding water outlet is extruded, water outlet goes out
Water, water-absorbing sponge soak or in dampness, at this moment wipe blackboard, fully achieve dust-free cleaning.
Embodiment 1: the sealing cover of rotation water filling port counterclockwise opens sealing cover, 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 all pours out the water in blackboard eraser reservoir bed,
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.
