Classification: CPC C  Y | IPC C

Claim 14:
15. A liquid dispensing unit, comprising:
a channel for fluid to flow there through;
a valve located adjacent to the channel for controlling a flow rate of the fluid flowing through the channel, wherein controlling the flow rate includes allowing the fluid to flow, varying a rate of flowing fluid, and stopping the fluid from flowing;
a set of ultraviolet radiation sources configured to irradiate an interior of the channel and the flowing fluid within the channel or the interior of the channel without the flowing fluid with ultraviolet radiation, the set of ultraviolet radiation sources configured to operate in a UV-C wavelength range;
a light guide configured to uniformly distribute the ultraviolet radiation, wherein the light guide comprises a layer including a plurality of regions formed of an ultraviolet transparent material, wherein at least one region in the plurality of regions is a protrusion structure;
a power supply connected to the set of ultraviolet radiation sources;
a filter fluidly connected to the channel, the filter configured to filter the fluid prior to irradiation, wherein the set of ultraviolet radiation sources are not located in the filter;
a control system including a set of processors configured to control and adjust the flow rate of the fluid flowing through the channel using the valve and the ultraviolet radiation generated by the set of ultraviolet radiation sources based on a set of current conditions, wherein the set of current conditions affect disinfection of the flowing fluid when the fluid is flowing or affect disinfection of the interior of the first channel when the fluid is not flowing; and
a user input component configured to receive a user input for the control system to adjust the ultraviolet radiation generated by the set of ultraviolet radiation sources.
