The invention brings forward an automatic liquid-dropping mask machine having a water-electricity separation function. The automatic liquid-dropping mask machine comprises a top cover assembly, a juicing cap, a juicing knife net assembly, a juicing cup, a machine body, a juicing motor, a middle support seat mechanism, a mask disc, a base support seat, a cleaning disc, a base, a water tank mechanism, a liquid discharge mechanism, a heating box stirring mechanism and a liquid-dropping mechanism. By arranging the water tank mechanism, the liquid discharge mechanism, the heating box stirring mechanism and the liquid-dropping mechanism and the like, problems such as automatic water discharge and manual water discharge are solved; the heating box stirring mechanism is utilized for heating so that a mask is rapidly coagulated; water-electricity separation is achieved; high intelligent degree is obtained; and the mask produced is uniform in thickness and rapid in coagulation speed.
