Connection.
In another technical solution, by the annular iron block 321 of setting in notch, annular magnet 332 is arranged in protrusion,
Being detachably connected for annular protrusion 331 and notch is realized, and then realizes housing 100 and holds being detachably connected for ash-pit 330.
In the dustfree electric blackboard eraser, as Figure 4-Figure 6, coaxially it is arranged in the rotation axis 221 of the motor 220
There is first gear 211；
The dustfree electric blackboard eraser, further includes the second rubbing head portion 400, and the second rubbing head portion 400 includes：
Second turntable 410 is arranged on outside the housing 100；
It is rotatably arranged on inside the housing 100 first rotating shaft 420, and parallel with rotation axis 221, the first rotating shaft
420 are pierced by the housing 100, and connect fixation with the middle part of one end of second turntable 410；
Second rubbing head 430, is detachably arranged in the other end of second turntable 410, and second rubbing head 430 is remote
One end end and one end end of first rubbing head 230 far from first turntable 210 from second turntable 410 is neat
It is flat；
Second gear 440, is coaxially set in the position that first gear 211 is corresponded in the first rotating shaft 420, and described
Two gears 440 are engaged with the first gear 211.
In another technical solution, in order to increase the area that blackboard eraser wipes ash, the efficiency that blackboard eraser wipes ash is improved, setting
Second rubbing head 430 is removably arranged on the second turntable 410 by the second rubbing head 430, such as the first rubbing head 230 and the first turntable
Then 210 connection relation sets first rotating shaft 420 on the second turntable 410, and the second tooth is set in first rotating shaft 420
First gear 211 on wheel 440, rotation axis 221 is set, and first gear 211 and second gear 440 is made to be meshed, is being rotated
When axis 221 rotates, first rotating shaft 420 is driven to rotate, it is achieved thereby that the rotation of the second turntable 410, passes through a motor
220, it is rotated while realizing the first rubbing head 230 and the second rubbing head 430, enhances the working efficiency of blackboard eraser.
In the dustfree electric blackboard eraser, there are two described second rubbing head, 430 400 settings.
In the dustfree electric blackboard eraser, as shown in fig. 6, the second turntable in two second rubbing heads 430 400

The center of circle be located on the same line.
In another technical solution, second turntable 410, three wipings are set respectively in the both sides of the first turntable 210
Head works at the same time more efficient, and the center of circle of two the second turntables 410 and the center of circle of the first turntable 210 are located at same straight line
On, i.e., by three rubbing head settings on one wire, reduce 220 unnecessary power loss of motor.
In the dustfree electric blackboard eraser, the radius phase of the radius of second turntable 410 and first turntable 210
Deng.
In the dustfree electric blackboard eraser, as shown in fig. 7, the second turntable of two second rubbing heads 430 400
410 center of circle and the center of circle of first turntable 210 are located on three vertex of an equilateral triangle respectively.
In another technical solution, second turntable 410, three wipings are set respectively in the both sides of the first turntable 210
Head work at the same time it is more efficient, and the center of circle of two the second turntables 410 and the center of circle of first turntable 210 form one it is equilateral
Triangle increases the area of rubbing head covering, improves rubbing head and wipes grey efficiency.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modification is easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
Specific details and legend shown and described herein are not limited to novel.
