[0068] Please refer to Figure 2 , Figures 5 to 8 The venting structure 4, the valve body piston structure 5, the valve core return spring 6, and the self-returning drive push plate 7 are assembled to form a venting valve assembly. This assembly is used to release the pressure inside the liquid oxygen storage cylinder 81 to a safe range under specific circumstances, thereby regulating the pressure and preventing excessive pressure in the liquid oxygen storage cylinder 81 from causing danger. The specific settings are as follows:

Figure 7 The valve body piston structure 5 includes a valve body mounting seat 51, an air guide pipe body 52, a sealing cone surface 53, a drive valve core 54, a cone surface sealing gasket 55, and a spring limiting protrusion 56; wherein, the valve body mounting seat 51 is fixedly connected to the air guide chamber seat 41; the two ends of the air guide pipe body 52 are respectively connected to the air receiving end 42 and the valve body mounting seat 51, and the air receiving end 42 is connected to the exhaust gas via the air guide pipe body 52 and the valve body mounting seat 51 in sequence. The ends 43 are connected in a closed manner; the inner wall of the channel of the valve body mounting base 51 is set as an inclined sealing cone surface 53 at one end near the air guide tube body 52; the drive valve core 54 is slidably mounted inside the valve body mounting base 51, and a conical sealing gasket 55 is fixedly connected to one end of the drive valve core 54. The conical sealing gasket 55 and the sealing cone surface 53 are detachably pressed and connected, so as to form a conical seal by the conical sealing gasket 55 and the sealing cone surface 53. The spring limiting protrusion 56 is fixedly connected to the outer periphery of the drive valve core 54, and the spring limiting protrusion 56 is slidably assembled inside the valve body assembly seat 51; the valve core return spring 6 is sleeved on the outer periphery of the drive valve core 54, and the valve core return spring 6 is correspondingly located between the spring limiting protrusion 56 and the inner wall of the valve body assembly seat 51, so as to effectively press the spring limiting protrusion 56 and the drive valve core 54 against the valve body assembly seat 51 by means of the rebound action of the valve core return spring 6. The core 54 allows the drive valve core 54 to continue pressing against the conical sealing pad 55, maintaining a contact seal between it and the sealing conical surface 53, thus forming a spring-pressed seal. At the same time, when the drive valve core 54 is subjected to a downward pulling force F from the self-returning drive push plate 7, the drive valve core 54 and the spring limiting protrusion 56 can overcome the rebound force of the valve core return spring 6 and drive the conical sealing pad 55 to release the spring-pressed seal, thereby effectively realizing the conduction of the exhaust air path along the air guiding direction a, improving the functionality and practicality.

[0071] Please continue to refer to this. Figure 5 and Figure 6The self-returning drive push plate 7 is configured as a tension spring type drive push plate structure.

The tension spring of the tension spring type drive push plate structure is connected to the outer wall of the valve body assembly seat 51 for limiting connection, so as to use the limiting effect of the tension spring to act as a lever fulcrum.

[0072] As a preferred embodiment, the outer wall of the drive valve core 54 is also fitted with a valve body sealing ring, which is pressed and sealed with the inner wall of the valve body mounting seat 51 to prevent the exhaust gas from leaking from the valve body piston structure 5, thereby ensuring the overall exhaust efficiency.

[0073] Please refer to Figure 8 The liquid extraction and transport structure 8 includes a liquid oxygen storage bottle 81 and a liquid extraction and transport pipe body 82 connected to the liquid oxygen storage bottle 81. The gas guide chamber seat 41 is also provided with a liquid extraction pipeline channel 44. The liquid extraction and transport pipe body 82 extends through the gas guide chamber seat 41 based on the liquid extraction pipeline channel 44, so that the liquid oxygen transported inside the liquid extraction and transport pipe body 82 can pass through the gas environment inside the gas guide chamber seat 41, thereby reducing the heat loss during the liquid oxygen transport process. At the same time, the liquid extraction and transport pipe body 82 and the gas guide chamber seat 41 can be integrated into a single design, further reducing the overall space occupied by the structure.
