Abstract

The invention discloses a white board electric wiper. A bottom box is fixed to the bottom of a white board. A left small motor and a left small wiper are arranged on the upper left corner of the white board. A right small motor and a right small wiper are arranged on the upper right corner of the white board. A battery is installed in the middle of the bottom box. A left large motor and a left large wiper are arranged on the left side of the battery. A right large motor and a right large wiper are arranged on the right side of the battery. A resistor is arranged on the left of the bottom box. A left large wiper switch, a right large wiper switch, a left small wiper switch, a right small wiper switch and a speed switch are arranged on the right of the bottom box. Autotruck windscreen wiper motors are adopted as the left large motor and the right large motor, and car windscreen wiper motors are adopted as the left small motor and the right small motor. When a teacher gives lessons, any of four switches can be selected according to needs to wipe content on the white board away, and wiping while writing is achieved in class; after class, all the content needs to be removed, the four switches can be turned on at the same time for removing, the speed of the wiper can be adjusted through the speed switch according to needs, and accordingly the white board electric wiper is very flexible, convenient to use and practical.

Description

Blank electric erasing
One, technical field
The present invention relates to one and wipe board for writing or drawing, relate in particular to one and 4 electric erasings are installed on blank, accomplish locally to wipe neatly as required, the blank electric erasing also can substantially wiped to all standing.
Two, background technology
A lot of blank is used in present teaching, but wipe blank and take the time very much, also require great effort very much, although have full automatic wiping blank or blackboard cleaning device, this device whole plate all will be wiped clean quickly, was therefore not suitable for teacher's upper class hour with the mode write with wiping, because teacher's upper class hour 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, such or pretty troublesome.
Three, summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of and 4 electric erasings are installed on blank, accomplish locally to wipe neatly as required, the blank electric erasing also can substantially wiped to all standing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of blank electric erasing, comprise blank, end box is fixed with bottom blank, left small machine is installed in the blank upper left corner, left small machine is installed left little wiping, right small machine is installed in the blank upper right corner, right small machine is installed right little wiping, in the middle part of end box, battery is installed, left heavy motor is installed on the battery left side, left heavy motor is installed left large wiping, right heavy motor is installed on the right of battery, right heavy motor is installed right large wiping, end box left part installs resistance, end box right part is installed a left side and is wiped switch greatly, switch is wiped greatly in the right side, left little wiping switch, right little wiping switch, speed switch.Left heavy motor, right heavy motor truck wiper motor, left small machine, right small machine car wiper motor.
The invention has the beneficial effects as follows, teacher at school time any one switch in 4 switches can be selected out as required to remove content on blank, accomplish that upper class hour can with writing with wiping, to all remove after class, just can open 4 switches to remove simultaneously, the speed of wiping can also be regulated as required with speed switch, so just very flexible, easily also very practical.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate the structure and characteristics of blank electric erasing of the present invention, in accompanying drawing:
Fig. 1 is the structure chart of embodiments of the invention one.
Fig. 2 is the circuit diagram of embodiments of the invention one.
1. blanks in figure, 2. end box, 3. left large wiping, 4. right large wiping, 5. left little wiping, 6. right little wiping, 7. left small machine, 8. right small machine, 9. resistance, 10. left heavy motor, 11. batteries, 12. right heavy motor, switch is wiped greatly in 13. left sides, and switch is wiped greatly in 14. right sides, 15. left little wiping switches, 16. right little wiping switches, 17. speed switches.
