ABSTRACT:
A coin-operated purified water dispensing machine has an exterior housing shaped like a kiosk for a mall. A state of the art water purification system is housed in the kiosk. A unique combination of an RO filter and a bladder type storage tank minimizes the necessary components to pump and measure the purified water. A unique tamper proof and bacteria resistant nozzle assembly includes a retractable nozzle having a shutter door to prevent access while in the passive mode. A pinch valve assembly controls the water flow in a non-invasive manner. Also a continuous flow of ozone to the nozzle assembly deters bacteria growth.
