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.

Claims

1. A water supply device for a vacuum bottle comprising:

an inner bottle formed with a concavity in its bottom;

an outer bottle having a top and enclosing said inner bottle;

a switch installed on the top of the outer bottle for the purpose of switching on and off an electrical power source for a motor;

a rotary gear located between said inner and outer bottles;

a motor used to drive said rotary gear;

said rotary gear having an upstanding peripheral rim and several magnetic poles spaced about an inner surface of said rim, said gear encircling the concavity of said inner bottle;

said inner bottle concavity is a magnetism transmissible concavity and is located in the middle of the bottom of said inner bottle;

a pump provided in the concavity of said inner bottle and having a shaft, a set of passive magnetic poles linked to said shaft, and multiple blades which are linked to and rotated with said shaft;

said pump having a plurality of water intakes communicating with said inner bottle and a water outlet pipe extending from said inner container outwardly of said outer bottle;

whereby when the motor is actuated by said electrical power source switch and said rotary gear surrounding the concavity is rotated, the magnetic flux of said gear'"'"'s magnetic poles is transmitted through said inner bottle concavity to make the magnetic poles on said pump shaft rotate, thus, rotating the multiple blades to force the water contained in said inner bottle out through the outlet pipe which extends out through said outer bottle.
