A portable oxygen bottle mask includes a breathing mask, which includes a mask and a fixed plug, the mask has an arc shape matching the mouth of the human body, and has a notch corresponding to the bridge of the nose, the fixed plug corresponds to the top of a canned oxygen bottle to make the breathing mask It can be installed in a canned oxygen cylinder, the central through hole of the fixing plug corresponds to the outlet tube of the oxygen cylinder, the height of the through hole is lower than the height of the top of the outlet tube； and a breathing rod, which has a shaft end and a pressing end, the shaft end is pivotally connected to One end of the plug is fixed so that the breathing rod can rotate at the pivot end as a fulcrum. The breathing rod contains a space. The face of the breathing rod near the air outlet has a first breathing hole, and the other side has at least a second breathing hole, the first breathing hole and the first The two breathing holes communicate with the space. The first breathing hole corresponds to the trachea. The first breathing hole includes at least one pressing part. The pressing part corresponds to the body of the trachea. When the breathing rod moves toward the trachea, the pressing part faces the trachea. The body exerts pressure to release the high-pressure gas in the canned oxygen bottle through the first breathing hole, space and second breathing hole for the user to breathe.一種隨身氧氣瓶面罩，包含一呼吸罩，其包含一面罩及一固定塞，面罩有配合人體嘴部之弧形，並有一對應鼻樑的缺口，固定塞對應一罐裝氧氣瓶之頂端使呼吸罩可安裝在罐裝氧氣瓶，固定塞之中央一貫孔對應氧氣瓶之出氣管，貫孔高度低於出氣管頂端高度；及一呼吸桿，其有一轉軸端及一按壓端，轉軸端樞接在固定塞之一端，使呼吸桿可以轉軸端為支點旋轉，呼吸桿包含一空間，呼吸桿靠近出氣管之一面有一第一呼吸孔，另一面有至少一第二呼吸孔，第一呼吸孔及第二呼吸孔連通該空間，第一呼吸孔對應出氣管，第一呼吸孔包含至少一按壓部，按壓部對應出氣管之管體，使呼吸桿朝向出氣管移動時，按壓部對出氣管之管體施壓而使罐裝氧氣瓶內的高壓氣體釋出後通過第一呼吸孔、空間及第二呼吸孔供使用者呼吸。
