The invention discloses a respiratory mask comprising an air pipe assembly and a shell. The air pipe assembly has a curved pipe body and a first connection portion, one end of the curved pipe body connects the first connection portion. The first connection portion has a first through hole, a first positioning portion, and a first ventilating portion. The curved pipe body and the first through hole form an airway together. The shell comprises a second positioning portion, and the second positioning portion rotatably mounted the first positioning portion. Wherein when the first positioning portion relatively rotates to the second positioning portion, the first ventilating portion and the curved pipe body also relatively rotates to the shell.本發明提出一種呼吸面罩，包含氣流管件與殼體。氣流管件包含彎曲管體與第一連接埠，彎曲管體的一端連接第一連接埠，第一連接埠具有第一貫孔部、第一定位部與第一通氣部，彎曲管體與第一貫孔部共同形成氣流路徑。殼體包含第二定位部，第二定位部可旋轉地套接第一定位部。其中當第一定位部相對於第二定位部轉動時，第一通氣部相對於殼體轉動，且彎曲管體也相對於殼體轉動。
