Principle of embodiment:

when the invention is used, the air outside the passenger cabin 3 is injected into the passenger cabin through the connecting column 5, thereby increasing the air pressure in the passenger cabin.

When the window is closed, the air pressure in the passenger compartment rises, the inner glass 9 is pressed towards the outside of the window, and the inner sealing layer 14 is close to the window frame sealing layer 18, so that good air tightness is ensured.

When a gap is formed between the inner sealing layer 14 and the window frame sealing layer 18 and the inner sealing layer fails, air in the passenger compartment passes through the gap and then enters the air bag through the air hole, and the air bag expands under high pressure, so that the second side edge 21 and the outer sealing layer 15 are tightly attached to each other, and the air is prevented from leaking between the window frame and the outer glass 10.

When the micro-pressure oxygen-enriched ambulance needs to pressurize a passenger cabin, the compressor 6 runs, gas enters the first sub-cavity 32 from the gas inlet 90, the inner cylinder 26 rotates anticlockwise (described by figure 4), the piston 31 moves towards the extrusion block 35, the spring is compressed, one end of the gas channel 37 on the supporting block 28 moves towards the gas outlet, and when the pressure at the extrusion block pressure sensor 36 reaches a certain value (according to hooke's law, the pressure can be considered as when the spring is compressed for a certain value), the force value is defined as a gas injection value; the end part of the air passage 37 is communicated with the air outlet, high-pressure air in the first sub-cavity 32 enters the passenger cabin through the air passage and the air outlet, and the air pressure in the passenger cabin is increased; by arranging the extrusion block pressure sensor 36, the pressure difference on two sides of the piston 31 is ensured to be constant when the compressor is used for pressurizing, so that the flow of the air outlet is ensured to be constant, the air pressure in the passenger cabin is ensured to be increased at a consistent speed, the phenomenon of 'steep first and then slow' of an air pressure rising curve is avoided, and the comfort of a human body is greatly improved; in the process of pressurization, the power of the compressor is automatically controlled according to the extrusion block pressure sensor 36, when the force value of the extrusion block pressure sensor 36 is smaller than the gas injection value, the power of the compressor is increased, and when the force value of the extrusion block pressure sensor 36 reaches the gas injection value, the power of the compressor is maintained; when the force value of the ram pressure sensor 36 exceeds the charge injection value, the compressor power is reduced.

When the air pressure in the passenger cabin reaches a certain value, the air pressure sensor sends a signal to the compressor 6, the compressor 6 stops running first, the spring extends, at the moment, the inner cylinder 26 rotates clockwise by a certain angle, the air passage 37 and the air outlet hole are staggered, the force value of the extrusion block pressure sensor 36 is reduced along with the extension of the spring, when the force value of the extrusion block pressure sensor 36 is reduced to a certain value, the extrusion block pressure sensor 36 sends a signal to the electric valve, the electric valve is closed, and at the moment, a closed cavity is formed in the first sub-cavity 32; then along with the passenger cabin loses heart, the atmospheric pressure in the passenger cabin reduces, and at this moment, the spring shortens, and inner tube 26 anticlockwise rotates, and air flue 37 moves towards the venthole, and extrusion block pressure sensor 36's power value risees, and when extrusion block pressure sensor 36's power value reachd the gas injection value (when air flue 37 reachd the venthole again promptly), send the signal and give electric valve and compressor 6, electric valve and compressor 6 all open, give the interior pressure boost of passenger cabin again.
