[0002] Currently, existing space capsule thermal insulation structures have significant shortcomings. On one hand, the selected insulation materials are relatively ordinary in performance, with low thermal resistance, resulting in poor resilience to extreme changes in external thermal environments. This makes it difficult to effectively maintain stable internal temperatures, increasing energy consumption of the environmental control system and posing potential risks to cabin comfort and equipment safety. On the other hand, the cabin's structural design, particularly the area beneath the bed, contains numerous hard-to-reach narrow gaps and dead corners. This design flaw makes daily cleaning and maintenance extremely inconvenient, easily accumulating dust and microorganisms, severely impacting the overall hygiene and air quality within the cabin. These problems collectively limit its reliability and user experience in practical applications.

[0027] Reference Figures 1 to 3 As shown, this utility model provides a space capsule thermal insulation structure, including:

[0028] The outer cabin 1 has a sealed door 3 hinged at the open end, and a glass window 6 is provided at the other end of the outer cabin 1;

[0029] The inner compartment 16 is fixedly installed inside the outer compartment 1, and a gap is left between the outer side wall of the inner compartment 16 and the inner side wall of the outer compartment 1.

[0030] The vortex cooling mechanism is fixedly installed on the outer compartment 1. The first outlet of the low-temperature end of the vortex cooling mechanism is connected to the inner compartment 16, and the second outlet of the low-temperature end of the vortex cooling mechanism is connected to the gap between the outer wall of the inner compartment 16 and the inner wall of the outer compartment 1. The vortex cooling mechanism is used to introduce low-temperature air into the inner compartment 16 and the gap between the outer wall of the inner compartment 16 and the inner wall of the outer compartment 1.

[0031] The exhaust mechanism is connected to the gap between the inner compartment 16 and the outer wall of the inner compartment 16 and the inner wall of the outer compartment 1.

[0032] Furthermore, the vortex cooling mechanism includes an air compressor 7, which is fixedly connected to the outer wall of the outer compartment 1. The outlet end of the air compressor 7 is fixedly connected to the inlet end of the vortex tube 9. The first outlet of the low-temperature end of the vortex tube 9 is connected to the inner compartment 16, and the second outlet of the low-temperature end of the vortex tube 9 is connected to the gap between the outer wall of the inner compartment 16 and the inner wall of the outer compartment 1.

[0033] Furthermore, a filter 8 is installed between the outlet end of the air compressor 7 and the inlet end of the vortex tube 9.

[0034] Furthermore, the first outlet of the cryogenic end of the vortex tube 9 is fixedly connected to the first air inlet pipe 10, which is connected to the inner cabin 16. The second outlet of the cryogenic end of the vortex tube 9 is fixedly connected to the second air inlet pipe 11, which is connected to the gap between the outer wall of the inner cabin 16 and the inner wall of the outer cabin 1.

[0036] Outside air at room temperature enters the air compressor 7 through the air inlet and is pressurized into high-pressure gas. The high-pressure gas first passes through the filter 8 and then enters the vortex tube 9. After being subjected to vortex action in the vortex tube 9, it forms low-temperature gas and high-temperature gas. The low-temperature gas enters the inner cabin 16 and the gap between the outer wall of the inner cabin 16 and the inner wall of the outer cabin 1 through the first air inlet pipe 10 and the second air inlet pipe 11, respectively. At the same time, the higher-temperature gas in both is discharged into the outside atmosphere through the first exhaust pipe 14 and the second exhaust pipe 12, respectively. In this way, the high-temperature gas in the space capsule is replaced with low-temperature gas, achieving a cooling effect. The air compressor 7 continuously delivers air into the space capsule, thus achieving the effect of maintaining the low temperature.

[0041] When the bed board 18 is laid flat and exposed, the occupant can lie flat on the bed board 18. When it is necessary to clean under the bed board 18, simply lift the end of the bed board 18 that is close to the support rod 20.

[0042] Furthermore, the sealed door 3 is hinged to the outer cabin 1 via a hinge 2, and a handle 4 is provided on the sealed door 3.
