Abstract

The invention discloses an electromagnetic water inlet valve capable of solving the problem that the normal work cannot be carried out due to excessively-low pressure. The electromagnetic water inlet valve comprises a valve body and a valve seat arranged in the valve body, wherein the valve body is provided with a conduit; a piston is arranged in the conduit; the head part of the piston is connected with a piston nut; a convex part is arranged at one end of the piston corresponding to the valve seat; the piston nut is arranged at the convex part; a diaphragm plate has a connecting structure which is provided with a moving space and a top buckle edge of the piston convex part; the piston convex part is positioned in the moving space; the axial length of the piston convex part is less than that of the moving space, so that the piston convex part is hooked with the top buckle edge of the connecting structure after moving towards the direction away from the valve seat for a stroke in the moving space; and the piston convex part continuously moves to drive the diaphragm plate and a diaphragm together to move towards the direction away from the valve seat. The invention is suitable for a water inlet valve of a washing machine and other home appliances.
