Abstract: An under counter drinking fountain of the present invention includes an electronic faucet. The electronic faucet includes an outlet pipe, a steam pipe, and a control device. The steam pipe is disposed with a valve. The control device can control liquid in the under counter drinking fountain to flow to the outlet pipe so as to output water for a user. The control device controls the valve to close the steam pipe as water is output from the outlet pipe. Thereby, it can not only avoid the liquid inside of the drinking fountain flowing out from the steam pipe, but also prevent the user from wasting water and scalding.

Abstract: A fluid control throttle valve includes a first tube and a second tube, both of which have an inner passage respectively. Between the first and second tubes are disposed an adjusting element and a cylindrical communicating element, wherein the adjusting element has a central axis and a plurality of throttling orifices axially disposed therein. The distance between the central axis and the throttling orifices, respectively, is substantially the same with each other, while the throttling orifices are arranged radially around the central axis of the adjusting element, wherein a bore diameter of at least one throttling orifice is different from that of the other throttling orifices. In addition, the communicating element has a through hole axially disposed therein. The communicating element is axially rotatable with respect to the central axis of the adjusting element, wherein the through hole thereof selectively communicates a selected throttling orifice.
