ABSTRACT:
A respiratory mask includes: a mask cap defining a chamber and a through-hole in fluid communication with the chamber; and a valve unit including a hollow valve body that projects in an axial direction from a periphery of the through-hole in the mask cap and that is formed with a valve seat which defines a valve opening in the valve body. The valve unit further includes an abutting plate that is securely connected to the valve body, and a single-piece elastic block body that is formed with a shoulder abutting sealingly against the valve seat, and that has a bottom end abutting against the abutting plate. The elastic block body is elastically compressible in the axial direction so as to be deformed in the axial direction to thereby space the shoulder apart from the valve seat when pressed by an external force.
