The utility model relates to an efficient saturated steam generator device which comprises a heating unit, and the heating unit comprises a heat-conducting shell with a groove formed in the top face, a heating
pipe located in the shell and spirally wound on the groove, and a water inlet
pipe spirally wound on the outer circumferential face of an inner cavity of the shell. When the steam generator is used, the heating
pipe is arranged to heat the shell, the shell transmits heat to the water inlet pipe, water in the water inlet pipe is vaporized to form steam, the water inlet pipe is spirally arranged, and the contact area of the water and the spiral pipe is increased, so that the water is vaporized quickly, the
steam generation time is shortened, and the
steam generation speed is increased; as the shell serves as a heat conduction medium between the heating pipe and the water inlet pipe, compared with the complex installation that the heating pipe and the water inlet pipe are directly connected for heat conduction, the arrangement of the shell facilitates installation of the heating pipe and the water inlet pipe, and meanwhile the
heating temperature of the heating pipe to the water inlet pipe can be conveniently monitored by monitoring the temperature of the shell.
