Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of embodiment of the present invention rotating mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As Fig. 1, shown in Fig. 2: a kind of Quick-dry dust-free blackboard eraser, comprise housing 1, handle 2 is connected with on the top of housing 1, this handle 2 is hollow-core construction, the inner side of handle 2 is provided with button 3, the side of housing 1 lower surface is provided with water outlet outer shaft 4, this water outlet outer shaft 4 can rotate relative to housing 1, multiple apopore 5 is distributed with at the surface uniform of water outlet outer shaft 4, and in the inner chamber of water outlet outer shaft 4, be also provided with axle 6 in water outlet, in this water outlet, the inner chamber of axle 6 is by the inner space of pipeline 7 with handle 2, in water outlet, the bottom of axle 6 is provided with interior apopore 8, water suction Wiping material layer 9 is wrapped with at water outlet outer shaft 4, and this water suction Wiping material layer 9 can disassemble from water suction rotating shaft 10, two sides that water suction Wiping material layer 9 is corresponding are respectively arranged with loop fastener structures, similarly, the absorbent material layer 11 be arranged on outside water suction rotating shaft 10 also can disassemble from water suction rotating shaft 10, cleans, the side rotational support relative with water outlet outer shaft 4 in the lower surface of housing 1 has the rotating shaft 10 that absorbs water, and water suction rotating shaft 10 is wrapped with absorbent material 11, and the sidewall of handle 2 is also provided with seal cover 12, housing 1 between water outlet outer shaft 4 and water suction rotating shaft 10 is also provided with scraping article 18, one end of water outlet outer shaft 4 is provided with rotating mechanism, rotating mechanism can drive water outlet outer shaft 4 to rotate, this rotating mechanism comprises a hollow turn knob 13, one end of turn knob 13 is provided with initiatively toothed edge 14, turn knob 13 is socketed on rotating driveshaft 15, rotating driveshaft 15 is provided with the passive toothed edge 16 corresponding with active toothed edge 14, and rotating driveshaft 15 can with water outlet outer shaft 4 common rotation, between rotating driveshaft 15 and water outlet outer shaft 4, be also provided with spring 17,
The course of work of the Quick-dry dust-free blackboard eraser of the embodiment of the present invention is as follows: when needing to use the blackboard eraser of the embodiment of the present invention to carry out the wiping of chalk writing, user is hold handle 2, the lower surface of housing 1 is allowed to contact with blackboard, and wipe according to the direction mobile blackboard of water outlet outer shaft 4 first contrectation erasing characters, while wiping, press the button 3 on handle 2, the water be stored in advance in handle 2 inner chamber is extruded, water can flow into axle 6 in water outlet by pipeline 7, and below axle in water outlet 6 side of blackboard (namely near) interior apopore 8 flow in water outlet outer shaft 4, multiple apopore 5 is circumferentially evenly distributed with due to water outlet outer shaft 4, therefore water body can by moistening to the water suction Wiping material layer 7 of contact portion with blackboard, such one side can improve wiping effect, chalk dust can also be allowed on the other hand to be adsorbed on water suction Wiping material layer 7 surface, prevent chalk dust from flying upward, the moisture remained on blackboard can strike off by scraping article 18 further afterwards, and absorbed by absorbent material 11 in the process that final residual moisture can roll in water suction rotating shaft 10, blackboard can realize reusing fast,
After using a period of time, when the side that water outlet outer shaft 4 carries out wiping has been stained with chalk dust and has affected wiping effect, the turn knob 13 of rotating mechanism can be pressed, turn knob 13 can drive the rotating driveshaft 15 be socketed with it to housing 1 internal motion, in the process of motion, owing to being provided with active toothed edge 14 and the passive toothed edge 15 of occlusion mutually between turn knob 13 and rotating driveshaft 15, after turn knob 13 loses pressure, meeting resilience under the effect of spring 17, in the process of resilience, passive toothed edge 15 can relatively rotate with active toothed edge 14, the angle of rotating is determined with the space width of passive toothed edge 14 (similar to ball pen laminated structure of being hit by a bullet) by active toothed edge 15, and the rotation of passive toothed edge 14 can drive water outlet outer shaft 4 to turn an angle, the face of now implementing wiping changes, wiping effect can be ensured.
When the absorbent material layer 9 outside water outlet outer shaft 4 is all stained with chalk dust, it can be disassembled from water outlet outer shaft 4 and clean, clean complete and after drying, be again wrapped on water outlet outer shaft 4, be fixed with the loop fastener structures of its dual-side.
When the absorbent material layer 11 outside the rotating shaft 10 that absorbs water all is stained with chalk dust, also it can be disassembled from water suction rotating shaft 10 and clean, clean complete and after drying, be again wrapped in water suction rotating shaft 10, be fixed with the loop fastener structures of its dual-side.
