Cleaning Alarm / Eraser cleaner

According to some research, after using the blackboard, the chalk dust which left on our hands may be very dangerous for our health, and it can cause some serious disease after a long term of using.

“There’s not only the eraser needs to be cleaned but also the hands.” This machine is the outcome which based on this concept.

There’s a sterilizing machine for the hands right under the eraser cleaner, once we are going to clean our eraser, it will sense that and turn on the sterilizing machine automatically and tell us to clean our hands at the same time.

From now on, the erasers and our hands are both ready for another teaching.
