[0002] As an important part of the aircraft oxygen system, the oxygen mask for civil aircraft passengers is an oxygen distribution device that provides emergency oxygen to passengers. Most of them are used to provide emergency oxygen to aircraft passengers in emergency situations such as cabin depressurization, smoke or fire. However, due to the lack of an adapter to connect the oxygen flow detection device, it is impossible to monitor the oxygen flow of the oxygen mask to determine whether it is working effectively. This poses a safety hazard to passengers using oxygen masks in an emergency. Utility Model Content
