Shell 20；Wiping arrangement is provided in the holding shell 20, the soft blackboard 10 is the closed loop configuration being freely rotated, the soft blackboard
In 10 rotation processes, the wiping arrangement is by 10 wiped clean of soft blackboard, so that the dust for the generation that erases the board is limited in
In the holding shell 20, the health that dust from flying endangers student and teacher is avoided.
As shown in Figure 2 and Figure 3, the wiping arrangement includes: fixed plate 23, blackboard eraser, 23 upper and lower ends of fixed plate with
The holding shell 20 is fixedly connected, and the blackboard eraser is connected in the fixed plate 23.
As shown in figure 3, the blackboard eraser includes: the first blackboard eraser 24, the second blackboard eraser 25, first blackboard eraser 24 is right
The soft blackboard 10 carries out first round wiping；Second blackboard eraser 25 carries out the second wheel to the soft blackboard 10 and wipes, by institute
The place that the first blackboard eraser 24 is not wiped clean is stated to wipe clean.
First blackboard eraser 24 is additionally provided with ultrasonic vibration apparatus (not shown), the ultrasonic vibration apparatus
The dust on first blackboard eraser 24 is shaken off in vibration, and avoiding gathering excessive dust on first blackboard eraser 24 leads to blackboard eraser
It is unclean.
Second blackboard eraser, 25 internal reservoir has water, so that the soft blackboard 10 is wiped more by second blackboard eraser 25
Completely.
As shown in Figures 1 to 3, the soft blackboard 10 includes: writing portion 11, cleaning part 12, rotation section 13；The writing portion
11, the rotation section 13, the connection of the cleaning part 12 form closed loop configuration, and 11 front of writing portion, the face D as shown in Figure 3 is used
It is used, 11 back side of writing portion, is contradicted in 20 outer surface of holding shell with writing；12 front of cleaning part, such as Fig. 3 institute
Show the face E, conflict has the blackboard eraser, and 12 back side of cleaning part contradicts in the fixed plate 23, and such structure realizes
The soft blackboard 10 is erased the board by the wiping arrangement during rotation.
As shown in Figure 2 and Figure 3, be provided with rotating device in the holding shell 20, the rotating device include: driven roller 21,
Driven voller 22, the driven roller 21 and the driven voller 22 are rotatablely connected with the holding shell 20, and the rotation section 13 is arranged
In the driven roller 21 and the driven voller 22, the rotation section 13 is driven by stiction when the driven roller 21 rotates
Rotation, so that the soft blackboard 10 be driven to rotate, such structure need to only drive the driven roller 21 to drive the soft blackboard 10
Rotation can erase the board, time saving and energy saving.
As shown in figure 3, motor 26 is also equipped in the fixed plate 23, to drive the driven roller 21 along side clockwise
