A hydrogen-oxygen breathing mask includes a mask body unit, a containing unit, and at least one gas generating unit connected to the containing unit. The cover unit includes a body suitable for covering the nose, and two wearing pieces. The accommodating unit is disposed on the inner surface of the body, and includes a liquid-holding member defining an accommodating space suitable for accommodating an action liquid, and the top of the liquid-holding member has a plurality of exhausts communicating with the accommodating space hole. At least one of the gas generating units includes a housing member and an electrolytic member adapted to electrolyze the working liquid into a hydrogen-oxygen mixed gas. By using the electrolysis element to electrolyze the action liquid to form the oxyhydrogen mixed gas, and in combination with the arrangement of the exhaust holes, the oxyhydrogen mixed gas can be discharged upwards and sucked by the user to achieve the effect of actively providing clean air.一種氫氧氣呼吸罩，包含一罩體單元、一容裝單元，及至少一連接該容裝單元的造氣單元。該罩體單元包括一適用於包覆鼻子的本體，及二配戴件。該容裝單元設置於該本體的內表面，並包括一界定出一適用於容裝一作用液體之容置空間的盛液件，該盛液件頂部具有多個連通該容置空間的排氣孔。至少一該造氣單元包括一殼體件，及一適用於將該作用液體電解成一氫氧混合氣體的電解件。藉由該電解件電解該作用液體形成該氫氧混合氣體，再配合該等排氣孔的設置，該氫氧混合氣體能向上排出並供使用者吸取，達成主動提供乾淨空氣的功效。
