Battery-Free Flushometer and Power System Therefor

원문 (중국어)

A battery-free flushometer includes a combination of a power generation system, a power storage system, and/or a power management system to enable the flushometer to operate without the need for connection to an external power source, changing spent batteries, or recharging spent batteries using an external power source, as well as structures supporting this functionality. The flushometer may include a valve assembly. The power generation system may include a hydraulic turbine assembly positioned downstream of the valve assembly and configured to generate power using the water discharged through the outlet, and/or a photovoltaic cell configured to generate electrical power by converting light energy to the electrical power. The power storage system is electrically connected to the power generation system and includes a power storage device to receive and store electrical power generated by the power generation system. The stored electrical power can be used to actuate the valve assembly.
