Abstract
The utility model provides an electric white board eraser. A bottom box is fixed to the bottom of a white board, a small left motor and a small left eraser are installed on the upper left corner of the white board, a small right motor and a small right eraser are installed on the upper right corner of the white board, a battery is installed in the middle of the bottom box, a large left motor and a large left eraser are installed on the left side of the battery, a large right motor and a large right eraser are installed on the right side of the battery, a resistor is installed on the left side of the bottom box, and a large left eraser switch, a large right eraser switch, a small left eraser switch, a small right eraser switch and a speed switch are installed on the right side of the bottom box. The large left motor and the large right motor are autotruck windscreen wiper motors, and the small left motor and the small right motor are car windscreen wiper motors. The content on the white board can be removed by a teacher through any one of the four switches according to requirements in class, the content can be written on the white board and can be erased at any time in class, and can be completely removed after class by switching on the four switches at the same time, the erasing speed can be adjusted through the speed switch according to requirements, and therefore the electric white board eraser is flexible, convenient to use and practical.
Description
One, technical field
The utility model relates to a kind of board for writing or drawing of wiping, and relates in particular to one 4 electric erasings are installed on blank, accomplishes local wiping neatly as required, the blank electric erasing that also all standing ground is wiped substantially.
Two, background technology
A lot of blanks are used in present teaching, but wipe blank and take very much the time, also require great effort very much, although have full automatic wiping blank or blackboard cleaning device, this device is whole plate all will be wiped clean quickly, is therefore not suitable for upper class hour of teacher with writing with the mode of wiping, because upper class hour of teacher must retain some important contents on blank, wipe the content that some are not wanted, must wipe by hand class hour so above device teacher is upper, so still pretty troublesome.
Three, utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of 4 electric erasings are installed on blank, accomplishes local wiping neatly as required, the blank electric erasing that also all standing ground is wiped substantially.
The utility model solves the technical scheme that its technical problem adopts: a kind of blank electric erasing, comprise blank, blank bottom is fixed with end box, left small machine is installed in the blank upper left corner, left little wiping is installed on left small machine, right small machine is installed in the blank upper right corner, right little wiping is installed on right small machine, battery is installed at box middle part, the end, left large motor is installed on the battery left side, left large wiping is installed on left large motor, right large motor is installed on battery the right, right large wiping is installed on right large motor, end box left part is installed resistance, end box right part is installed the left large switch of wiping, the right large switch of wiping, left little wiping switch, right little wiping switch, speed switch.Left large motor, right large motor truck wiper motor, left small machine, right small machine car wiper motor.
The beneficial effects of the utility model are, teacher can select out any one switch in 4 switches to remove the content on blank at school time as required, accomplish that upper class hour can be with writing with wiping, to all remove after class, just can open 4 switches removes simultaneously, can also regulate as required the speed of wiping with speed switch, so just very flexible, easily also very practical.
