Oxygen supply mask capable of sensing and alarming

The oxygen supply mask comprises a mask body, an oxygen supply bottle, a lower baffle, an upper baffle and an elastic band, a suction inlet is formed in the inner side of the mask body, and an alarm lamp and a loudspeaker are arranged on the outer side of the lower baffle. An oxygen sensor, a data module, a power module, a networking module, an analysis module, a main control module and an alarm module are arranged in the lower baffle. The oxygen sensor is connected with the oxygen supply pipe through the connector of the oxygen sensor, the oxygen sensor can measure oxygen concentration and flow at the same time and transmit data to the networking module and the analysis module, the data can be checked in real time through the networking module, oxygen content is analyzed through the analysis module, and signals of oxygen supply insufficiency or oxygen supply exceeding are sent to the main control module. The alarm module controls an alarm lamp and a loudspeaker to give an alarm, so that the content of oxygen
