The present invention provides a patient interface including a cushion assembly, a headgear assembly, an elbow assembly and transition ring structure and a headgear secure assembly. The cushion assembly, the elbow assembly and the headgear secure assembly are assembled together by the transition ring structure. The cushion assembly is sealed with a face of a patient when in use. The headgear secure assembly is for connecting the headgear so as to secure the patient interface at the face of the patient when in use. The cushion assembly is provided with a cylindrical wall for delivering an air flow, and the cylindrical wall projects in two opposite directions along an axis of an opening thereof, so as to provide an air flow of a breathing chamber with a flow diversion guiding effect. Thus, the patient interface can be worn and used with better comfort and convenience.
