NOVELTY - The utility model claims a graphene far infrared water heater driven by a voltage safety comprising a shell and a liner set in the shell; the liner is provided with an upper layer heating pipe connected with the power supply and the main control PCBA; a lower layer heating pipe set below the upper layer heating pipe; the heating pipe outer wall of the upper layer heating pipe and the lower layer heating pipe are provided with a graphene layer electrically connected with the main control PCBA; the upper layer heating pipe and the lower layer heating pipe generate far infrared heating effect after being electrified by the graphene layer; the heat is conducted to the water storage in the inner container; the inner part of the liner is provided with a water outlet pipe and a water inlet connected with the outside. The utility model solves the problem that the water heater structure in the existing technology has the hidden trouble of leakage safety
