NOVELTY - The generator has a box body provided with a water inlet and a steam outlet. A water tank is fixed on an inner wall of the box body. An electric heating sheet is arranged at an opening of the water tank and a metal-graphene composite. The water tank comprises a zigzag structure, so that water flow entering from a water flow reaches the steam outlet through the water tank. A steam generator body comprises a water outlet mechanism for preventing the water outlet from flowing out of water. A magnetizer is arranged at a side of the water inlet for magnetizing the water flow entering the box body. USE - Steam generator for use in a wireless steam mop (claimed) of a household floor cleaning device. ADVANTAGE - The generator is not easy to break, and outputs steam in real time under the condition of avoiding steam outlet water leakage and dry burning of electric heating sheet in the steam generator starting stage, utilizes steam outlet mechanism for preventing the steam outlet from flowing out of water, so that the base material of metal-graphene composite electric heat sheet is metal sheet, the toughness is better, the thermal expansion coefficient is closer to the temperature expansion coefficient of the graphene and the service life is long. The generator has quick heating speed and quick heat conduction speed, which shortens the time of water evaporation and the starting stage waiting for water evaporation time.
