The invention discloses an electric ion evaporator. The evaporator comprises a steam generation furnace body, a steam outlet is formed in the right side of the top of the steam generation furnace body, a water supplementing opening is formed in the left side of the bottom of the steam generation furnace body, a sewage draining opening is formed in the right side of the bottom of the steam generation furnace body, a low-voltage electrode electric ion heating body is installed on the right side of the steam generation furnace body, and a zero line protection terminal is mounted on the steam generation furnace body. Water is heated through the low-voltage electrode electric ion heating body, electric energy is directly and efficiently converted into heat energy, water molecules are promoted to be split into positive and negative electric ions in the heating process, the positive and negative electric ions flow between a positive electrode and a negative electrode, therefore energy is released, no intermediate medium is needed in the heating process, water becomes electrolyzed water in the heating process, scaling is avoided, the evaporator does not work in the absence of water, and the problem of breakdown due to water shortage is solved.
