The notification signal can be of a warning sound or a warning light or both. For example, when a current detecting circuit (not show) of the ultraviolet light detecting module 55 detects no current flowing through the UV LED, this means that the waterproof light emitting module 5 cannot emit ultraviolet light. In this instance, the current detecting circuit will send out a signal to activate a warning light and/or an alarm of the ultraviolet light detecting module and therefore generating the warning sound and/or the warning light.

(33) In summary, it can be seen that the ultraviolet light faucet of the present invention can sterilize the water flowing through the operation assembly 3 through the waterproof light-emitting module 5. Additionally, if needed, an indicating device 6 can be configured to emit a sterilization indicating light, such as blue light, to subsequently inform people that the water is currently in a sterilization process. Moreover, the present invention can be further configured with the mentioned above automatic manoeuvre set 12a and/or detecting device to increase the convenience of usage.
