Abstract
The utility model discloses a kind of Novel unpowered dust absorption blackboard eraser, comprise pedestal, evenly on the bottom surface of described pedestal be furnished with some spherical roller, other positions of base bottom surface are provided with wiping body, and the bottom surface of wiping body is concordant with the bottom surface of spherical roller; On described pedestal, the position of corresponding spherical roller is provided with the through hole placing spherical roller, and the through hole being arranged in Chuck top face is provided with fan, and spherical roller connects the driving shaft of fan by the power drive mechanism arranged in through-holes.The utility model can play dust suction effect without the need to power input, only dependence displacement, on the basis ensureing blackboard eraser pick-up performance, has saved the energy.
Description
Technical field
The utility model belongs to teaching aid technical field, particularly a kind of blackboard eraser.
Background technology
Blackboard eraser is one of requisite teaching aid in daily teaching process, and traditional blackboard eraser only has the function erased the board, and cannot absorb the dust granules produced in the process of erasing the board.Also there is blackboard eraser and the chalkboard eraser with dust suction effect in the market, such as: based on Small-sized suction cleaner, at the suction port place of main body, hairbrush has been installed, the dust absorbnig chalk eraser of dust removal port is set at body top; Also have with electric energy or solar energy dust absorbnig chalk eraser that is driven by energy etc.Although these products have certain dust suction effect, but there is following defect: 1) power of chalkboard eraser needs external energy source, no matter be solar energy or electric energy, all need to store energy in advance, the pick-up performance of the chalkboard eraser in period that can ensure to erase the board; 2) only provide the outlet of dust, but the gathering-device of dust is not provided, therefore can not the really high efficiency purification realizing air particle and pollute.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of without the need to power input, only rely on displacement can play the blackboard eraser of dust suction effect, on the basis ensureing blackboard eraser pick-up performance, and economize energy.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of Novel unpowered dust absorption blackboard eraser, comprises pedestal, evenly on the bottom surface of described pedestal is furnished with some spherical roller, and other positions of base bottom surface are provided with wiping body, and the bottom surface of wiping body is concordant with the bottom surface of spherical roller; On described pedestal, the position of corresponding spherical roller is provided with the through hole placing spherical roller, and the through hole being arranged in Chuck top face is provided with fan, and spherical roller connects the driving shaft of fan by the power drive mechanism arranged in through-holes.
Above-mentioned a kind of Novel unpowered dust absorption blackboard eraser, described power drive mechanism comprises radial direction and is arranged on waling stripe in spherical roller, the outer end of waling stripe connects worm-and-wheel gear, and worm-and-wheel gear connects the driving shaft of fan by the vertical connecting rod be axially disposed within through hole.
Above-mentioned a kind of Novel unpowered dust absorption blackboard eraser, described wiping body is sponge or hairbrush.
Above-mentioned a kind of Novel unpowered dust absorption blackboard eraser, described through-hole wall is stained with the filter paper for sucking chalk dust.
Above-mentioned a kind of Novel unpowered dust absorption blackboard eraser, described filter paper is nanometer filter paper.
Owing to have employed above technical scheme, acquired by the utility model, technological progress is as follows.
The utility model in use, the flowing of blackboard eraser surrounding air is caused with the rotation of fan, thus dust is brought in dust absorption blackboard eraser, the effect reducing blackboard periphery pellet pollution concentration can be played, to safeguarding that the health of teacher and front-seat student has remarkable effect; Further, the energy input that the utility model does not need the external world to provide any, relative to the chalkboard eraser in the past based on electric energy or solar energy, has saved the energy, more environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the transverse sectional view at wiping body position of the present utility model;
Fig. 3 is the structural representation of power drive mechanism described in the utility model.
Wherein: 1. pedestal, 2. spherical roller, 3. through hole, 4. fan, 5. waling stripe, 6. worm-and-wheel gear, 7. vertically connecting rod, 8. wiping body.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is described in detail.It should be noted that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of Novel unpowered dust absorption blackboard eraser, comprise pedestal 1 and wiping body 8, wiping body is fixedly installed on the bottom face of pedestal.In the utility model, wiping body is sponge or hairbrush.
Pedestal is provided with some through holes 3, in through hole, is provided with spherical roller 2, power drive mechanism 6 and fan 4.Be provided with six through holes in the present embodiment altogether, six even cloth of through hole on pedestal, as shown in Figure 1.
Wiping body sticks to position base bottom face not being arranged through hole, and spherical roller is arranged in wiping body, and as shown in Figure 2, the bottom surface of wiping body is concordant with the bottom surface of spherical roller.Fan 4 is positioned at the top of susceptor through-holes, is connected between fan with spherical roller by power drive mechanism.
Power drive mechanism comprises waling stripe 5, worm-and-wheel gear 6 and vertical links 7, the outer end that waling stripe 5 radial direction is arranged on waling stripe 5 in spherical roller connects worm-and-wheel gear 6, worm-and-wheel gear 6 connects the driving shaft of fan 4 by the vertical connecting rod 7 be axially disposed within through hole, as shown in Figure 3.
Through-hole wall of the present utility model is also provided with filter paper, for absorbing chalk dust.In the utility model, filter paper adopts nanometer filter paper, to ensure the dust Control sucked in chalkboard eraser to be unlikely to be diffused in the middle of the air outside chalkboard eraser in nanometer filter paper inside.
The utility model is in the process of erasing the board, move around along with of the present utility model, chalk dust is wiped from blackboard by wiping body, drive spherical roller to roll, spherical roller drives waling stripe to move up and down, and moving up and down of waling stripe is converted to the rotation of vertical connecting rod by worm-and-wheel gear simultaneously, thus drive the fan turns above vertical connecting rod, fan turns makes air flow, and sucks in blackboard eraser by contamination particles such as chalk dusts simultaneously, and filter paper is collected and prevented from flowing out.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all do within principle of the present utility model and spirit any amendment, equivalent to replace and improvement etc., be all just included within protection domain of the present utility model.
