Description

Technical Field

[0001] This utility model relates to the technical field of automobiles, and in particular to an oxygen generating device and the automobile thereof. Background Technology

[0002] Currently, vehicle-mounted oxygen generators generally employ molecular sieve pressure swing adsorption (PSA) technology, using an air compressor to provide compressed air, which is then separated and supplied to occupants. However, the nitrogen-rich gas produced simultaneously in this process is typically treated as exhaust gas and directly released into the atmosphere. This nitrogen not only possesses chemical inertness, which can be used to inhibit fuel oxidation, but also retains a certain pressure, enabling it to perform work. Its direct emission results in a double waste of energy and resources.

[0003] Meanwhile, vehicle seat massage functions mostly rely on independent air pumps or motors, increasing system complexity, cost, and risk of failure; while fuel anti-deterioration measures mainly rely on chemical additives or passive sealing, making it difficult to achieve active and dynamic control of the atmosphere inside the fuel tank. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. It provides an oxygen-generating device and its automotive counterpart, which achieves efficient resource utilization and system integration by using the byproduct nitrogen-rich gas for seat massage and fuel tank inerting.

[0005] To achieve the above objectives, this utility model provides an oxygen generating device, comprising:

[0006] An air compressor is used to draw in and compress ambient air;

[0007] A molecular sieve oxygen generation module is used to separate compressed air into oxygen and nitrogen-rich gas. The molecular sieve oxygen generation module includes an oxygen supply pipe, a first nitrogen supply pipe, and a second nitrogen supply pipe. The molecular sieve oxygen generation module is provided with an air inlet, an oxygen outlet, and a nitrogen outlet. The air inlet is connected to the air compressor, and the oxygen supply pipe is connected to the oxygen outlet. The oxygen supply pipe is used to provide oxygen to the occupants. The first nitrogen supply pipe and the second nitrogen supply pipe are respectively connected to the nitrogen outlet. The first nitrogen supply pipe is used to connect to the seat massage airbag, and the second nitrogen supply pipe is used to connect to the inerting air inlet of the fuel tank.

One end of the first compression branch is connected to the compressed air outlet, and the other end is connected to the air inlet. One end of the second compression branch is connected to the compressed air outlet, and the other end is used to connect to the seat massage airbag.

[0009] As a preferred embodiment, the air compressor includes a bypass control valve, and the first compression branch and the second compression branch are respectively connected to the compression outlet through the bypass control valve.

[0020] Compared with existing technologies, the oxygen generating device and its automotive embodiment of this utility model have the following advantages: by setting up an air compressor and a molecular sieve oxygen generating module, the nitrogen-rich gas directly emitted in the traditional oxygen generation process is converted into a reusable functional medium.

Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this utility model should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1 and Figure 3 As shown, a preferred embodiment of the present invention provides an oxygen generating device comprising:

[0034] Air compressor 10 is used to draw in and compress ambient air;

[0035] The molecular sieve oxygen generation module 20 is used to separate compressed air into oxygen and nitrogen-rich gas. The molecular sieve oxygen generation module 20 includes an oxygen supply pipe 21, a first nitrogen supply pipe 22, and a second nitrogen supply pipe 24. The molecular sieve oxygen generation module 20 is provided with an air inlet 26, an oxygen outlet 27, and a nitrogen outlet 28. The air inlet 26 is connected to the air compressor 10, and the oxygen supply pipe 21 is connected to the oxygen outlet 27. The oxygen supply pipe 21 is used to provide oxygen to the occupants. The first nitrogen supply pipe 22 and the second nitrogen supply pipe 24 are respectively connected to the nitrogen outlet 28. The first nitrogen supply pipe 22 is used to connect to the seat massage airbag 31, and the second nitrogen supply pipe 24 is used to connect to the inerting air inlet 41 of the fuel tank 40.

[0036] This invention relates to an oxygen-generating device and its accompanying vehicle. Through the installation of an air compressor 10 and a molecular sieve oxygen-generating module 20, it transforms the nitrogen-rich gas directly emitted during traditional oxygen generation processes into a reusable functional medium. The air compressor 10 provides compressed air, the molecular sieve oxygen-generating module 20 performs oxygen-nitrogen separation, and the oxygen supply pipe 21 outputs oxygen to meet the breathing needs of the occupants. The first nitrogen supply pipe 22 uses pressurized nitrogen-rich gas to drive the seat massage airbags 31, replacing an independent air pump or motor and reducing system complexity and energy consumption. The second nitrogen supply pipe 24 introduces nitrogen-rich gas into the upper space of the fuel tank 40, replacing oxygen to form an inert protective atmosphere and inhibiting fuel oxidation and deterioration. This oxygen-generating device integrates the previously isolated functions of oxygen supply, massage, and fuel protection into a single gas source system, realizing the utilization of the energy and chemical value of nitrogen-rich gas resources. This solves the technical problems of wasteful byproduct nitrogen-rich gas, system redundancy, high cost, and low energy efficiency in existing technologies.

[0037] It should be noted that ambient air contains impurities such as water vapor and carbon dioxide. To ensure the long-term stability of the molecular sieve oxygen generation module 20, it is preferable to install an air dryer and filter between the air compressor 10 and the molecular sieve oxygen generation module 20 to remove moisture, oil mist, and particulate matter. During the oxygen generation process, inert gases such as argon are not adsorbed and are discharged from the oxygen outlet 27 along with the oxygen. Residual carbon dioxide and water vapor are mainly discharged from the nitrogen outlet 28 along with the nitrogen. Therefore, although the gas output from the first nitrogen supply pipe 22 and the second nitrogen supply pipe 24 is not high-purity nitrogen, its inertness is sufficient to meet the requirements of seat massage and fuel tank protection.

[0038] Furthermore, such as Figure 1 As shown, the air compressor 10 includes a first compression branch 11 and a second compression branch 12. The air compressor 10 is provided with a compressed air outlet 13. One end of the first compression branch 11 is connected to the compressed air outlet 13, and the other end is connected to the air inlet 26. One end of the second compression branch 12 is connected to the compressed air outlet 13, and the other end is used to connect to the seat massage airbag 31. The air compressor 10 is divided into the first compression branch 11 and the second compression branch 12 through the compressed air outlet 13. The first compression branch 11 sends compressed air to the molecular sieve oxygen generation module 20 for oxygen generation, and the second compression branch 12 directly delivers unseparated compressed air to the seat massage airbag 31. The dual-branch structure allows the system to bypass the molecular sieve module and directly use compressed air for massage in scenarios where oxygen generation is not required, such as in plains areas. This reduces the ineffective start-stop and wear of the molecular sieve, extends its service life, and further improves the flexibility of energy utilization.

[0039] Furthermore, such as Figure 1As shown, the air compressor 10 includes a bypass control valve 14. The first compression branch 11 and the second compression branch 12 are respectively connected to the compressed air outlet 13 through the bypass control valve 14. The bypass control valve 14, as a flow distribution component, is integrated at the outlet of the air compressor 10 and is used to dynamically switch or adjust the distribution ratio of compressed air between the first compression branch 11 (oxygen production path) and the second compression branch 12 (massage path). Through the bypass control valve 14, the system can select pure nitrogen massage, compressed air massage, or a combination of both modes according to actual needs, achieving on-demand supply of massage air, avoiding gas waste, and improving user comfort and system response speed.

[0040] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the molecular sieve oxygen generation module 20 also includes a massage control valve 23, which is connected to the first nitrogen supply pipe 22. The massage control valve 23, located on the first nitrogen supply pipe 22, controls the inflation, pressure maintenance, and deflation sequence of nitrogen gas into the seat massage airbag 31. The periodic opening and closing of the massage control valve 23 drives the seat massage airbag 31 to expand and contract, achieving a simulated human hand massage effect.

[0041] In one specific embodiment, the massage control valve 23 includes a shut-off valve. The shut-off valve is installed on the first nitrogen supply pipe 22 and controls the flow of nitrogen to the seat massage airbag 31 by periodically opening and closing. When the shut-off valve is open, pressurized nitrogen enters the seat massage airbag 31, causing it to expand and providing massage pressure. When closed, the excellent sealing performance of the shut-off valve allows the seat massage airbag 31 to maintain a certain pressure, providing continuous support. Combined with the passive or active exhaust from the airbag exhaust port 34, a complete massage cycle can be completed.

[0042] In one specific embodiment, the massage control valve 23 includes a valve with adjustable flow rate, disposed in the first nitrogen supply pipe 22. The valve can be adjusted manually or electrically to control the flow rate of nitrogen entering the seat massage airbag 31, thereby adjusting the inflation rate and final pressure of the seat massage airbag 31 to meet the massage intensity needs of different users.

[0043] Furthermore, such as Figure 1 As shown, the molecular sieve oxygen generation module 20 also includes an inert gas control valve 25, which is connected to the second nitrogen supply pipe 24. The inert gas control valve 25, installed on the second nitrogen supply pipe 24, is used to regulate or switch the nitrogen flow to the fuel tank 40. During long-term fuel storage or in high-temperature environments, the inert gas control valve 25 can open to inject nitrogen to replace oxygen; once a stable inert atmosphere is formed inside the fuel tank 40, it can close to maintain a sealed state. The control settings of the inert gas control valve 25 can prevent pressure accumulation caused by continuous uncontrolled nitrogen injection, while ensuring the fuel oxidation inhibition effect.

[0044] In one specific embodiment, such as Figure 1 As shown, the inert gas control valve 25 is an electronic expansion valve. This electronic expansion valve is located on the second nitrogen supply pipe 24 and is electrically connected to the vehicle's control system. It can adjust the valve opening in real time based on the pressure or oxygen concentration signal within the fuel tank 40, thereby accurately controlling the injection flow and pressure of nitrogen into the fuel tank 40. In the initial stage of inertization, the electronic expansion valve can be fully open to quickly replace oxygen; when the oxygen concentration in the fuel tank 40 drops to a safe threshold, it automatically reduces the opening to maintain a slight positive pressure, preventing overpressure in the fuel tank 40 due to continuous high-flow nitrogen charging, thus achieving dynamic control of the fuel inertization process.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the end of the oxygen supply pipe 21 furthest from the oxygen outlet 27 is equipped with a diffusion oxygen supply interface 271 and / or a nasal oxygen supply interface 272. The diffusion oxygen supply interface 271 at the end of the oxygen supply pipe 21 is used to evenly release oxygen throughout the cabin. And / or, the nasal oxygen supply interface 272 is used for high-concentration, directional oxygen supply to meet oxygen needs in different scenarios. For example, diffusion oxygen supply is used in cases of mild hypoxia, while switching to nasal inhalation mode via the nasal oxygen supply interface 272 in cases of severe altitude sickness. This dual oxygen supply mode improves the adaptability and user experience of the oxygen supply system, while maintaining a simple structure and requiring no additional equipment.

[0046] A type of car, such as Figure 1 and Figure 3 As shown, it includes:

[0047] Oxygen generating equipment;

[0048] The seat assembly 30 is equipped with a seat massage airbag 31, which is connected to the first nitrogen supply pipe 22.

[0049] The fuel tank 40 has an inerting air inlet 41 at its upper part, which is connected to the second nitrogen supply pipe 24.

[0050] The oxygen generation device is integrated into the vehicle. The seat massage airbags 31 built into the seat assembly 30 directly receive nitrogen from the first nitrogen supply pipe 22, achieving motorless massage. The fuel tank 40 is connected to the second nitrogen supply pipe 24 through the inerting air inlet 41 on the top, forming active inerting protection. The entire vehicle does not require additional air pumps, additive systems, or independent protection modules, reducing weight, cost, and failure rate.

[0051] In one specific embodiment, a gas concentration sensor 48 is provided inside the fuel tank 40. The gas concentration sensor 48 is used to monitor the nitrogen or oxygen concentration in the upper gas phase space of the fuel tank 40 in real time. The gas concentration sensor 48 transmits the detection signal to the vehicle's control unit. The control unit adjusts the opening and closing state or opening degree of the inert gas control valve 25 according to a preset concentration threshold, thereby controlling the inertization process of the fuel tank.

[0052] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the seat assembly 30 also includes a nitrogen exhaust pipe 32. The seat massage airbag 31 has an airbag inlet 33 and an airbag exhaust outlet 34. The airbag inlet 33 is connected to the first nitrogen supply pipe 22, and the airbag exhaust outlet 34 is connected to one end of the nitrogen exhaust pipe 32, with the other end leading to the outside of the vehicle. After the seat massage airbag 31 completes its inflation and massage, it needs to be deflated promptly to return to its initial state. By setting up an independent nitrogen exhaust pipe 32, the nitrogen that needs to be discharged is directly led out of the vehicle, avoiding its accumulation in the passenger compartment, which could lead to local hypoxia or airflow turbulence, thus ensuring the reliability of the massage cycle and the safety of the air quality inside the vehicle.

[0053] Furthermore, such as Figure 1 As shown, the fuel tank 40 is equipped with a fuel tank vent 42, and a check valve 43 is installed at the fuel tank vent 42. When nitrogen is continuously injected into the fuel tank 40, the original oxygen-containing air and excess nitrogen inside must be discharged through the fuel tank vent 42 to maintain pressure balance. The check valve 43 allows internal gas to be discharged in one direction while preventing external air from flowing back in, ensuring that the fuel tank 40 always maintains a low-oxygen inert environment. This not only protects the system from overpressure but also effectively prevents secondary oxidation of the fuel, achieving long-term fuel protection.

[0054] Furthermore, such as Figure 1 As shown, the fuel tank 40 includes a first fuel tank 44 and a second fuel tank 46. The second nitrogen supply pipe 24 has a first interface 45 and a second interface 47. The first fuel tank 44 is connected to the first interface 45, and the second fuel tank 46 is connected to the second interface 47. For vehicles equipped with dual fuel tanks, such as motorhomes, by separately providing the first interface 45 and the second interface 47 on the second nitrogen supply pipe 24, nitrogen is supplied independently to the first fuel tank 44 and the second fuel tank 46, ensuring that both fuel tanks receive sufficient inerting protection and improving the fuel storage safety and reliability of the multi-tank system.

[0055] In summary, this utility model provides an oxygen generating device and its corresponding vehicle. Through the configuration of an air compressor 10 and a molecular sieve oxygen generating module 20, the nitrogen-rich gas directly emitted during traditional oxygen generation processes is converted into a reusable functional medium. Specifically, the air compressor 10 provides a compressed air source, the molecular sieve oxygen generating module 20 performs oxygen-nitrogen separation, and the oxygen supply pipe 21 outputs oxygen to meet the breathing needs of the occupants. The first nitrogen supply pipe 22 uses pressurized nitrogen-rich gas to drive the seat massage airbag 31, replacing an independent air pump or motor, thus reducing system complexity and energy consumption. The second nitrogen supply pipe 24 introduces nitrogen-rich gas into the upper space of the fuel tank 40, replacing oxygen to form an inert protective atmosphere and inhibiting fuel oxidation and deterioration. This oxygen generating device integrates the previously isolated functions of oxygen supply, massage, and fuel protection into a single gas source system, realizing the utilization of the energy and chemical value of nitrogen-rich gas resources. This solves the technical problems of wasteful by-product nitrogen-rich gas, system redundancy, high cost, and low energy efficiency in existing technologies.

[0056] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
