Claim 0:
1. A method of manufacturing a water inlet solenoid valve for enhancing a electromagnetic suction force, comprising:
obtaining a plastic-sealed stator assembly by injecting plastic on a stator assembly, comprising:
mounting an upper magnetic conductive inner sleeve and a lower magnetic conductive inner sleeve mounted in a hole of a coil assembly;
by injecting plastic on an inner surface of the upper magnetic conductive inner sleeve and the lower magnetic conductive inner sleeve, forming a water-isolating sleeve on the inner surface of the upper magnetic conductive inner sleeve and lower magnetic conductive inner sleeve;
mounting a yoke located outside the coil assembly and connecting the yoke with the upper magnetic conductive inner sleeves and the lower magnetic conductive inner sleeve;
mounting a magnetic conductive seat on an inner side of the water-isolating sleeve; and
by injecting plastic on the coil assembly and the yoke , forming 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;
assembling the plastic-sealed stator assembly and a valve body assembly comprising a movable iron core together 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 the lower magnetic conductive inner sleeve, so as to enhance the electromagnetic suction force of the water inlet solenoid valve.
