Chinese patent is that CN2000520104757.1 " a kind of water spray blackboard eraser " and CN200620075177.9 " the blank cleaning is wiped " disclose the be integrated method of use of whiteboard eraser and cleaning solution, but the whiteboard eraser of these patents has certain structure defective and potential safety hazard, extrude cleaning solution as all using injecting type, when being played by the student easily cleaning solution is injected eyes or penetrate on human body, cause damage to person, have certain potential safety hazard; Simultaneously, the structure of injecting type is attractive in appearance inadequately in appearance.
At above-mentioned situation, the present invention is exactly to consider various factors in order to address the above problem, whiteboard eraser be designed to safer, structure is simpler, is rich in attractive in appearancely simultaneously again, it is more convenient to make whiteboard eraser use, and has more the value of popularization.
Summary of the invention
The present invention is in order to solve the deficiency of common white blackboard eraser in the prior art, provide a kind of simple in structure, safer, easy to clean, do not waste, the whiteboard eraser of long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of whiteboard eraser, comprise and wipe main body and be located at the wiping portion of wiping on the main body, but be provided with the cavity volume of a splendid attire cleaning solution in the wherein aforesaid wiping main body, but wipe the bottle cap that main body is provided with the bottleneck that links to each other with cavity volume and is provided with the capping bottleneck; Wiping main body one side adjacent with wiping portion opened at least two guide holes that link to each other with cavity volume, and the port of guide hole is by the soft silica gel capping of a semicircle, and soft silica gel is provided with cross crack.When not using whiteboard eraser at ordinary times, the soft silica gel that guide hole is provided with can stop cleaning solution to flow in the wiping portion, this moment, the cross crack of soft silica gel closely connected, and had stopped the seepage flow of cleaning solution, when firmly main body is wiped in extruding, because the effect of cleaning solution pressure, slotted wall between the cross crack of soft silica gel breaks away from mutually at this moment, and promptly the gap in cross crack increases, and cleaning solution flow in the wiping portion, make wiping moistening, reach the effect of wiping blank; When the external pressure to cleaning solution disappeared, the cross crack of soft silica gel was returned to reset condition, and the sealing cleaning solution penetrates in the wiping portion.
As the further design to the aforementioned techniques scheme: aforesaid soft silica gel is a concave shape, and soft silica gel dents into cavity volume.The soft silica gel of depression has effectively been protected the unexpected seepage flow of cleaning solution; because it is big that the soft silica gel that the pressure ratio that makes the soft silica gel of depression produce deformation is protruded produces the pressure of deformation, this situation that has made cleaning solution seepage flow go out with regard to having prevented careless extruding gently from wiping main body takes place.
As to the aforementioned techniques scheme more further the design: aforesaid wiping main body both sides are provided with the pit bit of conveniently holding.Pit bit makes things convenient for the comfortableness of user's hand, can lower the possibility of whiteboard eraser from the hand landing simultaneously again.
In sum, whiteboard eraser of the present invention has convenient and practical, use safer, structure is simpler, is rich in simultaneously attractive in appearancely again, it is more convenient to make whiteboard eraser use, and has more the advantage of the value of popularization.
