This invention relates to the field of coffee machine brewing technology, and more specifically, to a vertical coffee spiral water outlet structure. This vertical coffee spiral water outlet structure of the present invention features an adjusting sleeve that simultaneously performs two functions: the outer passive gear receives power from a lifting motor to raise and lower the screw, while the bottom rotating gear receives power from a rotating motor to rotate the screw. A single component achieves a combined lifting and rotating motion, resulting in a highly integrated structure. The invention uses a universal ball joint as a water flow steering hub, allowing the outlet to swing at any angle in three-dimensional space while ensuring the liquid guiding channel remains connected, resolving the contradiction between motion and water delivery. The combined lifting and rotating motion of the screw causes the outlet to form a conical spiral trajectory above the coffee grounds layer, ensuring the water flow uniformly covers the entire surface of the coffee grounds, avoiding localized over-extraction or under-extraction.
