The invention provides a passenger breathing mask, and belongs to the technical field of breathing masks, the passenger breathing mask comprises a breathing base plate, the inner side and the outer side of the breathing base plate are sleeved with a face shell, the inner side of the breathing base plate is fixedly connected with a breathing block, the inner side of the breathing block is fixedly connected with a fixing rod, and the outer side of the fixing rod is rotatably connected with a rotating gear; the inner side of the breathing block is rotationally connected with symmetrically-distributed rotating rods, and the outer sides of the two rotating rods are fixedly connected with driven wheels. According to the breathing mask, the problems that the oxygen conveying amount of the breathing mask is fixed, passengers cannot adjust the oxygen conveying amount according to the demand quantity, and an oxygen connector is disengaged due to unstable connection are solved, the first ventilation cavity provides the needed oxygen amount for most passengers, and when the needed oxygen amount is increased due to passengers, the passenger opens a sealing plate, an oxygen suction channel is added through a second ventilation cavity, and more oxygen can be sucked by adding a conveying channel for the passenger to suck oxygen.

    本发明提供旅客呼吸面罩,属于呼吸面罩技术领域,包括呼吸基板,所述呼吸基板的内侧外侧套接有面壳,所述呼吸基板的内侧固定连接有呼吸块,所述呼吸块的内侧固定连接有固定杆,所述固定杆的外侧转动连接有转动齿轮,所述呼吸块的内侧转动连接有对称分布的转杆,两个所述转杆的外侧均固定连接有从动轮。本发明解决了呼吸面罩的氧气输送量是固定的,乘客不能根据需求量进行调节,氧气连接头连接不稳定会出现脱落的问题,本发明中,通过第一通气腔为大多数乘客提供需求的氧气量,当有乘客紧张需求的氧气量增加,乘客使封闭板打开通过第二通气腔增加氧气的吸取通道,乘客吸取氧气的输送通道增加可以吸取更多的氧气。
