The invention relates to a heating electrolysis hydrogen production and plasma generation device. The device comprises a cup body and a base body, and the cup body comprises a shell and a non-metal water container, wherein a primary electromagnetic coil and a secondary electromagnetic coil are arranged on the outer surface of the non-metal water container, and a first electrode part, a second electrode part, a third electrode part, a hydrogen production electrolysis first electrode part and a hydrogen production electrolysis second electrode part are arranged in an inner cavity of the non-metal water container. According to the invention, a low-voltage electromagnetic induction method is adopted; a primary electromagnetic coil connected with the power supply part is electrified to generatea magnetic field; the third electrode part generates electromagnetic induction to heat water; the secondary electromagnetic coil induces electric potential under the influence of a magnetic field; apotential difference is generated between the first electrode part and the second electrode part, so that an electric arc is generated at the moment of contact, water bubbles are broken through, and plasma is generated; in addition, the hydrogen production electrolysis first electrode part and the hydrogen production electrolysis second electrode part also perform electrolysis hydrogen productionin water at the same time, and the heating, electrolysis hydrogen production and plasma generation can be realized at the same time.
