ABSTRACT:
A touch-controlled switch for electrical pneumatic vacuum flask, including a switch plate with which a glass or the like contacts, a gutter connected to an air cavity, a venting tube connected to the gutter, a fine switch disposed in a lid of the vacuum flask, and a touch rod disposed under the fine switch and fixedly inserted in a top portion of the vacuum flask. A spring is fitted to the touch rod, whereby when using one hand to hold a glass or the like and press the same against the switch plate, a sealing rod formed therebehind will seal an outlet of the venting tube to kept the air contained in an internal vessel tightly enclosed therein. A lateral projection is formed on the sealing rod for lifting the touch rod to touch the fine switch and consequently activate a motor to pump air into the internal vessel for discharging water therefrom. When removing the glass from the switch plate, the touch rod is descended via extending force of the spring and separated from the fine switch to stop discharging water. Furthermore, the switch plate is downward pressed by the touch rod, permitting the sealing rod to leave the outlet of the venting tube and allow air contained in the internal vessel to escape therefrom.
