Self-powered miniature liquid treatment system

摘要

A liquid treatment system (2804) that may be self-powered includes a filter (2972), an ultraviolet light source (2984) and a hydro-generator (2992) in a first flow path. The first flow path may provided treated liquid at a first outlet (2816) of the liquid treatment system (2804). A second flow path included in the liquid treatment system may provide untreated liquid at a second outlet (2818) of the liquid treatment system (2804). The first and second flow paths may be included in a housing (2808), and may be selectable with a switching mechanism by a user of the liquid treatment system (2804). The housing (2808) may be mounted at the end of a faucet (2802). The hydro-generator (2992) may generate electric power for use by the ultraviolet light source (2984) and a processor. The processor may monitor the electric power and energize the ultraviolet light source (2984) with the electric power when the rotational speed of the hydro-generator (2992) enters a determined range.
