Power supplying device for improved water heater

The utility model relates to a modified water heater power supply device; the generating set comprises a rotating member and a generating member; the rotating member is matched with the outlet of a water pressure inlet valve; the rotating member has a turbine, and a shaft lever is arranged in the center of the turbine; the generating member comprises a coil seat sleeved on one end of the shaft lever, and a ring permanent magnet is arranged in circle at the lateral of the coil seat; the generating member is electrically coupled with the power supply device by a conductor; by adopting the components, the water can flow toward the generating device by the water pressure inlet valve to enable the water to drive the rotating member and enable the combined generating member to produce electric power; then the electric power produced by the generating member is transported to the power supply device to be stored and provided for the use of high voltage ignition device; therefore enabling no blackout of the water heater.
