ABSTRACT:
A water supply device for vacuum bottle used a space at the bottom outside the inner bottle to install a power driving device to drive a gear. The gear has two magnetic poles provided by a permanent magnetic iron using to repel or attract the other magnetic poles located at the concavity to rotate. These poles use the same shaft with a multiple blade gear, therefore, as the magnetic poles rotate, the water inside the inner bottle can be squeezed and flow out through outlet pipe.
