An automatic ozone water output device includes a faucet unit, at least one water inlet pipe, and an ozone generator. The faucet unit will automatically detect the presence of a user to output water. The water inlet pipe having a Venturi section connects the faucet unit and a water source. An ozone generating device having a pressure-sensitive activator is kept in a concealed space or a sheltered location, such as in the area under a basin or a sink. When water flows through the Venturi pipe, a negative pressure is developed and sensed by the pressure-sensitive activator. In response, the pressure-sensitive activator activates the ozone generator, thereby causing the mixing of ozone with the discharged water.
