Claim 6:
7. A water inlet solenoid valve for enhancing a electromagnetic suction force, which comprises:
a plastic-sealed stator assembly comprising:
a coil assembly;
an upper magnetic conductive inner sleeve and a lower magnetic conductive inner sleeve mounted in a hole of the coil assembly;
a water-isolating sleeve formed by injecting plastic into an inner surface of the upper magnetic conductive inner sleeve and the lower magnetic conductive inner sleeve;
a yoke located outside the coil assembly and connecting the upper magnetic conductive inner sleeves and the lower magnetic conductive inner sleeves;
a magnetic conductive seat mounted on an inner side of the water-isolating sleeve; and
a plastic-sealed layer used to cover the coil assembly and to tightly connect the yoke with the upper magnetic conductive inner sleeve and lower magnetic conductive inner sleeve;
a valve body assembly comprising a movable iron core, for assembling with the plastic-sealed stator assembly to form the water inlet solenoid valve;
wherein an upper end face of the movable iron core at an initial position is slightly higher than an upper edge of lower magnetic conductive inner sleeve, so as to enhance the electromagnetic suction force of the water inlet solenoid valve.
