[0026] The following describes the oxygen chamber according to an embodiment of the present utility model with reference to the drawings.

[0027] Referring to Figures 1 to 3 , the oxygen chamber according to an embodiment of the present utility model includes a chamber body 1 and an oxygen supply system 2. The chamber body 1 includes a chamber door 3. After opening the chamber door 3, users can enter or leave the chamber body 1. The chamber body 1 can be provided with seats and the like for users to rest, and multimedia devices for users to entertain. After closing the chamber door 3, a closed or substantially closed space can be formed inside the chamber body 1. When the oxygen supply system 2 works, it can supply compressed air and oxygen to the inside of the chamber body 1 simultaneously, or supply only compressed air or oxygen to the inside of the chamber body 1 during a certain period, so as to form an oxygen-rich environment with a pressure greater than one atmosphere inside the chamber body 1. For example, an environment with 1.3 times the standard atmospheric pressure and an oxygen concentration of 30% is formed.

[0028] The oxygen supply system 2 is arranged below the chamber body 1. Specifically, the oxygen chamber further includes a bracket 4. The chamber body 1 is supported by the bracket 4, and the main structure of the oxygen supply system 2 is installed on the bracket 4.

[0029] Now referring to Figures 4 to 7 , the oxygen supply system 2 includes a refrigerant, a compressor 5, a condenser 6, a first expansion valve 7, a second expansion valve 8, a first evaporator 9, a second evaporator 10, and a third evaporator 11.

[0030] The refrigerant can be a substance with reversible phase change (such as gas-liquid phase change) such as R410A refrigerant and Freon.

[0031] After the compressor 5 sucks in the gaseous refrigerant, it is mechanically compressed into a high-temperature and high-pressure gaseous refrigerant.

[0032] The main function of the condenser 6 is to cool and liquefy the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 5. Inside the condenser 6, the refrigerant exchanges heat with the surrounding air or water through heat dissipation fins or tube bundles, and releases the heat to the external environment, thereby cooling and liquefying into a liquid refrigerant.

[0033] The first expansion valve 7 and the second expansion valve 8 can throttle and depressurize the refrigerant cooled by the condenser 6, turning it into a low-temperature and low-pressure liquid-gas mixed refrigerant, creating conditions for the evaporation of the refrigerant in the corresponding evaporator. The first expansion valve 7 and the second expansion valve 8 can also adjust the flow rate of the refrigerant entering the corresponding evaporator.

[0034] The first evaporator 9, the second evaporator 10, and the third evaporator 11 can convert the incoming low-temperature and low-pressure liquid-gas mixed refrigerant into a gas. During this process, the refrigerant absorbs the heat around the first evaporator 9, the second evaporator 10, and the third evaporator 11. The evaporated refrigerant is then sucked back into the compressor 5 to start a new cycle.

[0035] Specifically, the compressor 5, the condenser 6, the first expansion valve 7, the first evaporator 9, and the corresponding pipes form the first refrigerant circuit. The compressor 5, the condenser 6, the second expansion valve 8, the second evaporator 10, and the corresponding pipes form the second refrigerant circuit. The compressor 5, the condenser 6, the second expansion valve 8, the third evaporator 11, and the corresponding pipes form the third refrigerant circuit.

[0036] The oxygen supply system 2 further includes a first air compressor 12, a second air compressor 13, a blower 14, a box body 15 (the top cover of the box body 15 is not shown), a first cooling tank 16, a second cooling tank 17, and an oxygen generator assembly 18.

[0037] The box body 15 is separated into a first chamber and a second chamber by a partition 19. The first evaporator 9 is arranged in the first chamber, and the first air compressor 12 and the second air compressor 13 are both arranged in the second chamber. The first chamber is formed with an air inlet 20 through which external air can enter the first chamber, and the partition 19 is formed with a plurality of air holes. The blower 14 can promote the flow of air between the first chamber and the second chamber. In this embodiment, the blower 14 is arranged in the second chamber.

[0038] During the circulation of the refrigerant in the first loop, the first evaporator 9 can cool the surrounding air. The cooled air is driven by the fan 14 and enters the second chamber through the air holes. Part of the cooled air entering the second chamber is absorbed and pressurized by the first air compressor 12 and the second air compressor 13 to generate compressed air, and the other part cools the first air compressor 12 and the second air compressor 13, and then enters the first chamber through the air holes and is cooled again. In one embodiment, part of the cooled air can also cool the first air compressor 12 and the second air compressor 13, and then be absorbed and pressurized by the first air compressor 12 and the second air compressor 13 to generate compressed air. During the process that the first air compressor 12 and the second air compressor 13 absorb the air in the box body 15 and pressurize it to generate compressed air, the inside of the box body 15 is continuously in a negative pressure state, and the air outside the box body 15 enters the first chamber through the air inlet 20 to supplement the air in the box body 15.

[0039] The air output end of the first air compressor 12 is connected to the air inlet of the first cooling tank 16 through the first air pipe 21, and the air output end of the second air compressor 13 is connected to the air inlet of the second cooling tank 17 through the second air pipe 22. The second evaporator 10 is arranged in the second cooling tank 17, and the third evaporator 11 is arranged in the first cooling tank 16. During the circulation of the refrigerant in the second loop, the second evaporator 10 can cool the compressed air entering the second cooling tank 17. During the circulation of the refrigerant in the third loop, the third evaporator 11 can cool the compressed air entering the first cooling tank 16. The air outlet of the second cooling tank 17 is connected to the oxygen generator assembly 18 through the third air pipe 23. The oxygen generator assembly 18 can include a filter, a separator, etc. The oxygen generator assembly 18 can separate the oxygen in the compressed air cooled by the second cooling tank 17 and transport the separated oxygen to the oxygen chamber through the gas pipe. The specific structure of the oxygen generator assembly 18 is not limited in this embodiment. The compressed air cooled by the second cooling tank 17 can be directly transported to the oxygen chamber through the gas pipe.

[0040] The oxygen supply system 2 of the oxygen chamber in this embodiment has the functions of generating compressed air and oxygen at the same time. The "sub-system" for generating compressed air and the "sub-system" for generating oxygen share a set of "compressor 5, condenser 6", which reduces the occupied space of the oxygen supply system 2 and can effectively reduce the manufacturing cost of the oxygen supply system 2.

[0041] In this embodiment, the oxygen supply system 2 further includes a third expansion valve 24 and a fourth evaporator 25. The compressor 5, the condenser 6, the third expansion valve 24, the fourth evaporator 25 and the corresponding pipes form the fourth loop of the refrigerant.

[0042] The third expansion valve 24 can throttle and depressurize the refrigerant cooled by the condenser 6, turning it into a low-temperature and low-pressure liquid-gas mixed refrigerant, creating conditions for the evaporation of the refrigerant in the corresponding evaporator. The third expansion valve 24 can also adjust the refrigerant flow rate into the fourth evaporator 25.

[0043] The fourth evaporator 25 can convert the incoming low-temperature and low-pressure liquid-gas mixed refrigerant into a gas. During this process, the refrigerant absorbs the heat around the fourth evaporator 25. When the fourth evaporator 25 is arranged in the cabin 1, the fourth evaporator 25 can absorb the heat in the cabin 1, that is, absorb the heat in the area supplied with compressed air and / or oxygen. Thus, the oxygen supply system 2 can have the functions of generating compressed air, oxygen, and regulating the temperature in the cabin 1. The "sub-system" for generating compressed air, the "sub-system" for generating oxygen, and the "sub-system" for temperature regulation in the cabin 1 share a set of "compressor 5, condenser 6", which can effectively reduce the manufacturing cost of the oxygen supply system 2.

[0044] Preferably, the first expansion valve 7, the second expansion valve 8, and the third expansion valve 24 are all electronic expansion valves. The oxygen supply system 2 can also include a control circuit, which is electrically connected to the first expansion valve 7, the second expansion valve 8, and the third expansion valve 24, and is used to control the opening degrees of the first expansion valve 7, the second expansion valve 8, and the third expansion valve 24, so as to control the heat absorption of each evaporator.
