Utility model effect and effect
The automatic blackboard eraser that the utility model provides, owing to having cleaning part and drive division, cleaning part comprises close adhesion plate face and arranges and the brush body extended along blackboard short transverse and housing for supporting brush body, drive division comprises the driving wheel that blackboard is close on the drive motors be fixed on housing and the axle being horizontally installed on drive motors and edge, therefore, drive motors can drive driving wheel left rotation and right rotation, make the force of rolling friction of driving wheel promote housing to move ahead, and then hence brush member moves left and right and wipes writing on plate face, thus do not need teacher manually to erase the board, realize the object of automatic blackboard cleaning.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is arranged on blackboard in an embodiment; And
Fig. 2 is the structural representation that the utility model is placed separately in an embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Fig. 1 is the structural representation that the utility model is arranged on blackboard in an embodiment.
Fig. 2 is the structural representation that the utility model is placed separately in an embodiment.Fig. 2 is the rearview of Fig. 1, and has concealed blackboard 20.
As shown in Figure 1, automatic blackboard eraser 10 comprises cleaning part 1 and drive division 2.
As depicted in figs. 1 and 2, cleaning part 1 is slidably mounted on blackboard, can move and Wiper plate face along blackboard 20 length direction.Drive division 2 is connected on cleaning part 1 for driving cleaning part 1 to move.Control part is for controlling drive division work.
Wherein, cleaning part 1 comprises the setting of close adhesion plate face and the brush body 15 extended along blackboard 20 short transverse; And for supporting the housing 11 of brush body 15.The surface of brush body 15 arranges fine hair, more easily wipes the writing on plate face.The shape of brush body 15 is cylinder.Certainly, the brush body in the present embodiment can also be cube.
Housing 11 has the upper mounting plate 13 and lower installation board 12 that are fixedly connected on brush body 15 top and bottom respectively, and upper surface 131 and the lower surface 121 of blackboard 20 are stuck between upper mounting plate 13 and lower installation board 12.
The upper surface 131 of blackboard 20 and lower surface 121 arrange the first orbit determination and the second orbit determination that extend along blackboard 20 length direction respectively, upper mounting plate 13 is provided with the first dynamic rail corresponding with the first orbit determination, and lower installation board 12 is provided with the second dynamic rail corresponding with the second orbit determination.Two groups of settings moving rail and orbit determination, can reduce the frictional force between housing 11 and blackboard 20.
Drive division 2 comprises the drive motors 21 be fixed on housing 11; And the driving wheel 22 of blackboard 20 is close on the axle being horizontally installed on drive motors 21 and edge.Drive motors 21 drives driving wheel 22 to rotate, and make the force of rolling friction of driving wheel 22 promote housing 11 and move ahead, and then hence brush member 15 moves left and right and wipes writing on plate face.
Drive division 2 comprises the controller be connected with drive motors 21, and controller is fixed on housing 11 surface, controller is provided with the button controlling drive motors 21 and work.
Housing 11 both sides are also provided with for preventing chalk dust to the baffle plate 14 of external diffusion, chalk dust down can only be dropped in enclosure interior, and can not fly away in the mouth and nose of teacher, decrease the harm of chalk dust to teachers ' health.
Use procedure: teacher can control the starting or stoping of drive motors 21, forward or reverse by the button on controller, thus control driving wheel 22 respectively and move or static, left-handed or dextrorotation.When driving wheel 22 rotates, force of rolling friction between driving wheel 22 and blackboard 20 is greater than housing 11 and the frictional force between brush body 15 and blackboard 20, thus make the force of rolling friction of driving wheel 22 can promote housing 11 to move ahead, and then hence brush member 15 moves left and right and wipes writing on plate face.
Embodiment effect and effect
Automatic blackboard eraser in the present embodiment, owing to having cleaning part and drive division, cleaning part comprises close adhesion plate face and arranges and the brush body extended along blackboard short transverse and housing for supporting brush body, drive division comprises the driving wheel that blackboard is close on the drive motors be fixed on housing and the axle being horizontally installed on drive motors and edge, therefore, drive motors can drive driving wheel left rotation and right rotation, make the force of rolling friction of driving wheel promote housing to move ahead, and then hence brush member moves left and right and wipes writing on plate face, thus do not need teacher manually to erase the board, realize the object of automatic blackboard cleaning.
Certainly, the automatic blackboard eraser that the utility model relates to not merely is defined in the description in above embodiment.
