Abstract

A faucet configured to discharge ozone water comprises a faucet body, a water mixing valve mechanism, a water processor, a control switch, a processor, a control valve, and a detector configured to detect whether water is flowing through the detector. The faucet body comprises a faucet outlet, and the water mixing valve mechanism comprises a cold water inlet connected to a cold water resource, a hot water inlet connected to a hot water resource, and a mixed water outlet. The water processor comprises a water processing passage and an ozone generator connected to the water processing passage. The control valve is disposed between the cold water resource and an inlet of the water processing passage, and an outlet of the water processing passage is connected to the faucet outlet. The detector is disposed between the mixed water outlet of the water mixing valve mechanism and the inlet of the water processing passage, and the processor is electrically connected to the control switch, the ozone generator, the detector, and the control valve to close the control valve and the ozone generator when the detector detects the water flowing through the detector.
