Urinal or wash basin with integral power source has magnetic valve to control water flow driven by miniature water power generator

摘要

The bathroom urinal (1) has a magnetic valve controlled by an infrared sensor (12) controlling the water outlet with a micro water-power generator connected to the outlet. The generator has a water duct and a regulator for the generator section. The duct feeds into a chamber with flow ports and a vane wheel carrying magnets. The magnets act on an induction spool when rotated to produce electric power for a battery with a rectifier diode, a Zener diode and a current control resistance to operate the magnetic valve.
