[0002] The full name of the air film is the air-supported membrane structure, which is a new type of building form that has emerged with the development of new materials and new technologies. It uses a special building fiber membrane material as the "outer shell" and forms a building space by supporting the "outer shell" through an automated pressurization and fresh air system. It is a brand-new building form that integrates technologies such as architecture, structural mechanics, new materials science, mechatronics, and automatic control. Regarding the issue of the safety of the use of air film buildings, in addition to the quality of the air film material itself, the most important thing is whether the air film airtight door can relieve pressure and leak air.

[0003] During the use of existing air film buildings, a corresponding number of air film airtight doors will be set up for the convenience of entry and exit. When the air film airtight door is in use, if it is opened for a long time, the internal pressure of the air film building will become smaller. However, during the use of existing air film airtight doors, whether the air film airtight door is opened is not monitored, and it is easy to ignore the opening and closing state of the air film airtight door. If the air film airtight door is opened for a long time, the internal air pressure of the air film structure will become smaller, posing a risk of the air film structure collapsing and causing personal safety problems to the staff inside the inner wall of the air film structure. Content of the Utility Model

[0004] The purpose of the utility model is to provide an alarm device for monitoring the pressure relief and air leakage of an air film airtight door.
