[0039] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following examples can be combined with each other without conflict.

[0040] Example 1:

[0041] As Figures 1-8 shown, the automobile seat cabin oxygen supply and massage integrated gas supply system proposed by the present application includes a control module 1, an air compressor 2, an oxygen supply unit 3, a massage unit 4 and a carbon dioxide reduction unit 6.

[0042] The control module 1 is the core of the whole system, responsible for controlling the running state of each unit, ensuring the stability and efficiency of the system. The control module 1 can use microprocessors, single-chip microcomputers and other intelligent control devices to realize automatic control of the system through pre-set programs and algorithms.

[0043] The air compressor 2 is configured to output compressed air to provide compressed air for the oxygen supply unit 3 and the massage unit 4. The air inlet of the air compressor 2 is connected with a filter device 7 to filter impurities in the air. The air compressor 2 can be selected according to actual needs.

[0044] As Figure 1 or Figure 2 or Figure 6 As shown, the oxygen supply unit 3 is connected to the air compressor 2 to obtain compressed air, and separates the oxygen in the compressed air through an oxygen separation module 31, stores it in an oxygen storage tank 32, and finally supplies it to the passengers in the cabin through an oxygen supply terminal 33. The oxygen supply terminal 33 is arranged at the headrest of the car seat, and the oxygen supply terminal 33 releases oxygen by detecting the breathing rate of the human body, so that passengers can directly inhale oxygen during the ride. The oxygen separation module 31 can use molecular sieve components and other high-efficiency separation technologies to ensure the purity and quality of oxygen supply.

[0045] As Figure 1 or Figure 3 or Figure 7As shown, the massage unit 4 is connected to the air compressor 2 to obtain compressed air, and stores the compressed air in the massage air tank 41, and implements air pressure massage on the passenger through the massage air bag 42. The massage air bag 42 is arranged at the backrest of the car seat, covering the back of the passenger, and providing a comfortable air pressure massage experience. The massage unit 4 further includes an exhaust pipeline 43 connected to the massage air bag 42 and the air inlet of the air compressor 2, so as to quickly exhaust the air in the massage air bag 42 by the suction of the air compressor 2. The exhaust pipeline 43 is only provided with one pipeline, so as to form a negative pressure on the exhaust pipeline 43, and the air in the massage air bag 42 can be completely exhausted, thereby enhancing the dynamic effect and comfort of the massage.

[0046] In addition, the oxygen supply unit 3 and the massage unit 4 are connected to the air compressor 2, and a first switching valve 5 is arranged for switching the air path. The first switching valve 5 is configured to selectively deliver the compressed air to the oxygen supply unit 3 or the massage unit 4, so as to realize flexible switching and efficient operation of the system. The first switching valve 5 can be an electromagnetic valve, a pneumatic valve or other types of valves, which can be selected according to actual needs.

[0047] As shown in Figure 1 or Figure 4 or Figure 8 As shown, the carbon dioxide reduction unit 6 is configured to deliver the air in the car cabin to the air compressor 2 and discharge the cabin through the molecular sieve assembly 310 to reduce the carbon dioxide concentration in the cabin. The carbon dioxide reduction unit 6 includes a cabin backflow pipe 61 connected to the car cabin, and a second switching valve 62 connected to the air inlet of the air compressor 2. The second switching valve 62 is configured to selectively control the air compressor 2 to draw the air inside the cabin through the cabin backflow pipe 61 or draw the air outside the cabin, so as to realize the circulation treatment of the air in the cabin and the introduction of fresh air from the outside.

[0048] The control module 1 is further configured to control the air path switching between the air compressor 2 and each unit according to the oxygen supply, carbon dioxide concentration and massage demand in the cabin. The control module 1 intelligently controls the operating state of each unit by monitoring the oxygen concentration and carbon dioxide concentration in the cabin and the massage demand of the passengers in real time. In order to realize this function, oxygen concentration detection devices and carbon dioxide concentration detection devices are arranged in the cabin to monitor the oxygen and carbon dioxide concentrations in the cabin in real time and feed back the data to the control module 1. When it is detected that the oxygen concentration in the cabin is lower than the preset value, the control module 1 controls the air compressor 2 to deliver compressed air to the oxygen supply unit 3, the oxygen supply unit 3 separates the oxygen and other gases in the compressed air and stores the oxygen in the oxygen storage tank 32, and the pressure sensor is arranged in the oxygen storage tank 32, when the pressure in the oxygen storage tank 32 reaches the preset value, the control module 1 controls the compressor 2 and the first reversing valve 5 to deliver compressed air to the massage unit 4. If it is detected that the carbon dioxide concentration in the cabin is higher than the preset value, the control module 1 controls the carbon dioxide reduction unit 6 to deliver the air in the cabin to the air compressor 2 for processing, and the compressed air is discharged to the outside of the cabin through the molecular sieve assembly 310.

[0049] In this application, when the carbon dioxide reduction unit 6 is started, the second reversing valve 62 can only deliver the cabin air of the cabin body return pipe 61 to the air compressor 2, when the carbon dioxide concentration in the cabin is reduced to the preset value, the second reversing valve 62 switches the air path communicated with the cabin body return pipe 62, and can only deliver the air outside the cabin to the air compressor 2.

[0050] In the embodiment, the molecular sieve assembly of the oxygen separation module 31 adopts high-efficiency separation technology, which can efficiently separate the oxygen from other gases in the compressed air, and discharge the separated other gases to the outside of the cabin, avoiding the influence of other gases on the air quality in the cabin. At the same time, the massage air bag 42 of the massage unit 4 is made of soft and breathable material to ensure the comfort and safety of massage.

[0051] The working principle is as follows:

[0052] When the passenger needs to inhale oxygen, the control module 1 judges whether the oxygen concentration in the cabin is sufficient according to the data of the oxygen concentration detection device. If the oxygen concentration is insufficient, the control module 1 controls the air compressor 2 to work, and delivers the compressed air to the oxygen supply unit 3 through the first reversing valve 5. The oxygen separation module 31 separates the oxygen from the compressed air and stores it in the oxygen storage tank 32. The oxygen supply terminal 33 releases oxygen by detecting the breathing frequency of the passenger.

[0053] When the passenger needs massage, the control module 1 controls the air compressor 2 to work according to the massage demand, and delivers the compressed air to the massage unit 4 through the first reversing valve 5. The massage air tank 41 stores the compressed air, and delivers the compressed air to the massage air bag 42 through the pipeline. The massage air bag 42 performs air pressure massage on the back of the passenger according to the preset program and algorithm.

[0054] When the carbon dioxide concentration in the cabin is too high, the control module 1 judges whether the carbon dioxide concentration needs to be reduced according to the data of the carbon dioxide concentration detection device. If the carbon dioxide concentration needs to be reduced, the control module 1 controls the second reversing valve 62 to switch the air path, so that the air compressor 2 extracts the air inside the cabin through the cabin backflow pipe 61 for processing. At the same time, the control module 1 can adjust the working state of the air compressor 2 to increase the extraction amount of the air inside the cabin, thereby effectively reducing the carbon dioxide concentration in the cabin.

[0055] The control module 1 can also intelligently adjust according to the actual situation in the cabin. For example, when the oxygen concentration and the carbon dioxide concentration in the cabin need to be adjusted at the same time, the control module 1 can prioritize the demand for oxygen supply; when the passenger needs massage while inhaling oxygen, the control module 1 can coordinate the working state of the oxygen supply unit 3 and the massage unit 4 to ensure that both can normally operate at the same time.

[0056] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed in the present application can be easily thought by those skilled in the art, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
