The upper lid of a coffee includes an upper lid body, which is provided inside with a rotatable receiving unit having a female-threaded portion and a central through hole. A support post fitted with a prop member is inserted upward through the central through hole of the rotatable receiving unit and fitted around with a safety valve unit. Then, the rotatable receiving unit and the upper lid are combined together, and the top end of the support post is fitted with a warning member movably positioned in the central through hole of the upper lid. Thus, the steam produced by boiling water inside the coffee maker can push up the safety valve body to force the warning member to protrude out of the through hole of the upper lid, manifestly warning a user not to directly open the upper lid to avoid scalded.
