ABSTRACT:
An electric thermos bottle capable of automatic water release/cutoff which has an automatic water release/cutoff power switch turned on by the weight of a cup placed thereon. When the power switch is on, it actuates an electric air pump inside the top head of the thermos bottle to produce compressed air which passes an air communicating pipe and enters the sealed thermos bottle. At this point, the air pressure in the thermos bottle suddenly increases and therefore, forces water reserved in the thermos bottle to automaticaly release from a blow off pipe before flowing into the cup below a water exit. When water in the cup reaches a predetermined level, the water completes an override circuit which includes conductive elements in the cup and the metal interior of the thermos, in order to disconnect the air pump and automatically discontinue the release of water. An air valve is located above the air communicating pipe and will automatically open when the release of water is discontinued to thereby form a steam passage which prevents water reserved in the thermos bottle from overflowing.
