[0073] When the human body is in a state of hypoxia, problems such as slowed reaction speed and drowsiness will occur, especially in the driving state, which is likely to cause safety accidents.

[0074] Carbon dioxide is an important indicator for judging indoor air. The concentration of carbon dioxide in normal air is about 0.04%. If the concentration increases, people may feel nausea, headache and other discomforts. When the indoor carbon dioxide concentration is below 0.07%, it is clean air, and the human body feels good at this time; when the carbon dioxide concentration is 0.07%-0.1%, it is ordinary air, and some sensitive people may feel uncomfortable; when the carbon dioxide concentration is 0.1%-0.15%, the indoor air properties begin to deteriorate, and people begin to feel uncomfortable; when the concentration is 0.3%-0.4%, people's breathing deepens, and symptoms such as headache, tinnitus, slow pulse, and increased blood pressure appear, which may endanger people's lives in severe cases. Taking a 7-seater car with a 4m3 interior space as an example, when 7 people are seated, the carbon dioxide concentration in the car reaches 0.1% in 1.5 minutes, and it will reach 0.5% in about 9 minutes. If not handled in time, it will greatly endanger human health.

[0075] See also Figure 1 , Figure 2 as well as Figures 6 to 9 The present application proposes a vehicle air treatment method, which can be used to treat the air inside the vehicle 100, comprising the following steps:

[0076] S100: Detect the real-time oxygen supply signal of the vehicle 100, and determine whether the oxygen supply condition is met according to the real-time oxygen supply signal. If so, supply oxygen to the interior of the vehicle 100.

[0077] The real-time oxygen supply signal of the detection vehicle 100 includes detecting the oxygen concentration inside the vehicle 100, the altitude of the vehicle 100 and the biological signals related to the oxygen supply of the passengers. Since the oxygen concentration inside the vehicle and the altitude of the location of the vehicle 100 will affect the changes in the biological signals of the oxygen supply of the passengers, it can be determined whether it is necessary to supplement oxygen to the inside of the vehicle 100 by obtaining the real-time oxygen supply signal of the vehicle 100. In this example, the real-time oxygen supply signal can be obtained directly or indirectly. The direct acquisition of the real-time oxygen supply signal refers to directly detecting the oxygen concentration inside the vehicle 100, the altitude information of the vehicle 100 and the biological signals of the passengers; the indirect acquisition of the real-time oxygen supply signal refers to the oxygen concentration inside the vehicle 100, the altitude signal of the vehicle 100 and the biological signals of the oxygen supply of the passengers obtained by reading other detection equipment. The other equipment may include wearable devices, systems provided by the vehicle 100 and other independently installed equipment.

[0078] Judge whether the oxygen supply condition is met according to the real-time oxygen supply signal, including comparing the real-time oxygen supply signal with a preset oxygen supply value. When the oxygen supply condition is met, oxygen can be supplied to the interior of vehicle 100. The supply of oxygen to the interior of vehicle 100 includes replenishing the pre-stored oxygen to the interior of vehicle 100, or may include generating oxygen through an oxygen generation device 232 and inputting the generated oxygen into the interior of vehicle 100 to improve the oxygen concentration in vehicle 100.

[0079] S200: Detect the real-time carbon dioxide concentration inside vehicle 100, and judge whether the real-time carbon dioxide concentration reaches a preset carbon dioxide concentration. If so, process the carbon dioxide inside vehicle 100.

[0080] Judging whether the real-time carbon dioxide concentration inside vehicle 100 reaches the preset carbon dioxide concentration means comparing the detected real-time carbon dioxide concentration with the preset carbon dioxide concentration. When the real-time carbon dioxide concentration is higher than the preset carbon dioxide concentration, it can be inferred that the carbon dioxide concentration inside vehicle 100 exceeds the preset range. At this time, it is necessary to reduce the carbon dioxide concentration inside vehicle 100. In this example, the carbon dioxide concentration inside vehicle 100 can be reduced by supplementing air to the interior of vehicle 100, or the carbon dioxide concentration inside vehicle 100 can be reduced by physical or chemical means, and the processed air is input into vehicle 100 to circulate the air inside vehicle 100.

[0081] In the example of this application, it is judged whether it is necessary to improve the air state inside vehicle 100 according to the real-time oxygen supply signal or the real-time carbon dioxide concentration signal inside vehicle 100, and then the air state inside vehicle 100 can be adjusted in real time to make the air inside vehicle 100 suitable for the physical state of the passengers.

[0082] In this application, step S100 can be executed first, and then step S200 can be executed. Alternatively, the above steps can be swapped. Optionally, in the example of this application, steps S100 and S200 can also be executed simultaneously.

[0083] In some examples, in the above step S100, the real-time oxygen supply signal includes the real-time oxygen concentration. The method of judging whether the oxygen supply condition is met according to the real-time oxygen supply signal includes judging whether the real-time oxygen concentration is less than the preset oxygen concentration. If so, it is judged that the oxygen supply condition is met. In this example, the real-time oxygen concentration can be obtained by acquiring the air inside the vehicle and comparing the real-time oxygen concentration with the preset oxygen concentration. When the real-time oxygen concentration is less than the preset oxygen concentration, it means that the oxygen content in the current air inside the vehicle is too low, and oxygen needs to be supplied to the interior of the vehicle. In this example, the real-time oxygen concentration signal can be obtained by a sensor located inside the vehicle, and the sensor can be installed at a preset position on the vehicle.

[0084] In some examples, in the above step S100, the real-time oxygen supply signal includes the real-time altitude. The method for determining whether the oxygen supply condition is met based on the real-time oxygen supply signal includes determining whether the real-time altitude is greater than the preset altitude. If so, it is determined that the oxygen supply condition is met. In this example, the altitude of the vehicle can be detected to determine the oxygen supply signal. When the altitude of the vehicle is greater than the preset altitude, oxygen is supplied to the interior of the vehicle. In this example, the altitude of the current location of the vehicle can be detected by devices such as an altitude sensor.

[0085] In some examples, in the above step S100, the real-time oxygen supply signal includes the real-time human blood oxygen saturation. The method for determining whether the oxygen supply condition is met based on the real-time oxygen supply signal includes determining whether the real-time human blood oxygen saturation is less than the preset human blood oxygen saturation. If so, it is determined that the oxygen supply condition is met. In this example, the real-time oxygen concentration of the passengers inside the vehicle can be obtained, and the real-time oxygen concentration is compared with the preset oxygen concentration. When the real-time oxygen concentration is less than the preset oxygen concentration, it indicates that the blood oxygen concentration of the current passenger is too low, and oxygen needs to be supplied to the interior of the vehicle. In this example, the real-time oxygen concentration signal can be obtained by a sensor located inside the vehicle. The sensor can be installed on the vehicle, or it can be a blood oxygen saturation sensor integrated on a wearable device of the passenger and capable of measuring blood oxygen concentration.

[0086] In some examples, the real-time oxygen supply signal includes at least two of the real-time oxygen concentration, the real-time altitude, and the real-time human blood oxygen saturation. It is possible to determine whether the oxygen supply condition is met only through a single signal, or it is also possible to determine whether the oxygen supply condition is met through multiple signals. Optionally, the real-time oxygen supply signal simultaneously includes the real-time oxygen concentration, the real-time altitude, and the real-time human blood oxygen saturation. One of the devices for obtaining the above signals can be selected to be turned on. Different devices can complement each other. When one device is on standby or shut down, another device is started to obtain the oxygen supply signal to ensure that the oxygen supply signal can be continuously obtained, and thus ensure that the oxygen supply inside the vehicle meets the preset requirements.

[0087] Please refer to Figure 3 , in some examples, in step S100, detecting the real-time oxygen supply signal of the vehicle, and the method for determining whether the oxygen supply condition is met based on the real-time oxygen supply signal includes the following steps:

[0088] S110: Obtain the real-time oxygen supply signal.

[0089] In this example, the real-time oxygen supply signal can be obtained by the detection component 210, and the detection component 210 can be a sensor. The detection component 210 can be installed at a preset position on the vehicle 100. In the example of this application, the detection component 210 can be installed inside the vehicle 100 so that the detection component 210 can be used to detect the air signal inside the vehicle 100 and / or the passenger's biological signal. The air signal inside the vehicle 100 can include the oxygen content, carbon dioxide content or the content of other specific gases inside the vehicle 100. Taking the oxygen content inside the vehicle 100 as an example, the detection component 210 can be used to detect the oxygen concentration inside the vehicle 100. The passenger's biological signal refers to measuring the passenger's biological signal by means of sound, light, electricity or a combination thereof. The passenger's biological signal in the example of this application can be the passenger's blood oxygen concentration, blood carbon dioxide concentration, etc.; in some examples, the detection component 210 can be electrically connected to a wearable device worn by the passenger himself to obtain the passenger's biological signal obtained by the wearable device. The detection component 210 can also include a device for detecting the altitude signal of the vehicle 100. Since the oxygen content in the air will gradually decrease as the altitude increases, the current oxygen content in the air can be inferred by obtaining the altitude signal, and then it can be determined whether the current oxygen content inside the vehicle 100 meets the requirements. Optionally, multiple identical or different detection components 210 can be arranged inside the vehicle 100 to detect the real-time oxygen supply signals of multiple parts of the vehicle 100. The detection component 210 in this example can be independently installed at a preset position inside the vehicle 100. Optionally, the detection component 210 can also be integrated with other functional modules on the vehicle 100 to improve the space utilization rate of the vehicle 100.

[0090] S120: Compare the real-time oxygen supply signal with the preset oxygen supply value, and determine whether the difference between the preset oxygen supply value and the real-time oxygen supply signal reaches a first preset range. If so, determine that the real-time oxygen supply signal meets the oxygen supply condition.

[0091] The preset oxygen supply value may be a preset parameter set according to at least one of the number of passengers, altitude, or other parameters. In this example, the obtained real-time oxygen supply signal is compared with the preset oxygen supply value in the system to determine the difference between the current preset oxygen supply value and the real-time oxygen supply signal. As the oxygen in the vehicle interior is consumed, when the difference between the preset oxygen supply value and the real-time oxygen supply signal reaches a first preset range, it indicates that the oxygen supply in the current vehicle interior may be insufficient. At this time, it can be determined that the real-time oxygen supply signal reaches the oxygen supply condition, and oxygen needs to be supplemented into the vehicle interior. The first preset range can be any preset value. In this example, the first preset range can be determined according to the number of passengers in the vehicle, altitude, and other parameter information of the passengers. When the preset oxygen supply value is greater than or equal to the real-time oxygen supply signal, the oxygen supply in the current vehicle interior meets the demand, and oxygen may not be supplied into the vehicle interior, or a small amount of oxygen can be supplied into the vehicle interior.

[0092] In this example, it is determined whether the real-time oxygen supply signal inside the vehicle 100 exceeds the preset oxygen supply value. If so, the first air source is inhaled and high-concentration oxygen is generated. The oxygen concentration of the high-concentration oxygen is greater than the oxygen concentration of the first air source. The first air source can be at least one of the air inside the vehicle 100 and the air outside the vehicle 100. When the air inside the vehicle 100 is used as the first air source, the air inside the vehicle 100 can be processed to increase the oxygen concentration of the air and generate high-concentration oxygen. When the air outside the vehicle 100 is used as the first air source, the gas outside the vehicle 100 can be inhaled and processed to generate high-concentration oxygen. In this example, the oxygen concentration of the high-concentration oxygen is higher than the oxygen concentration of the first air source, and thus a gas with a high oxygen concentration can be formed. The high-concentration oxygen is input into the vehicle 100 to increase the oxygen concentration inside the vehicle 100. In this example, one or more oxygen outlets 7e can be provided inside the vehicle 100 to input the high-concentration oxygen to one or more positions inside the vehicle 100.

[0093] Determine the first difference between the real-time oxygen supply signal inside the vehicle 100 exceeding the preset oxygen supply value. In this example, the real-time oxygen supply signal inside the vehicle 100 exceeds the preset oxygen supply value. As the real-time oxygen supply signal inside the vehicle 100 increases, the first difference will also gradually increase. In this example, the amount of high-concentration oxygen input into the vehicle 100 can be determined according to the magnitude of the first difference, and thus the oxygen supply can be dynamically regulated according to the real-time oxygen supply signal inside the vehicle 100, so that the oxygen content inside the vehicle 100 can be balanced with the preset oxygen supply amount, and a relatively appropriate oxygen supply state can be maintained inside the vehicle 100.

[0094] Please refer to Figure 4 , in some examples, in step S100, the method for supplying oxygen to the vehicle interior includes the following steps:

[0095] S130: Supply oxygen to the vehicle interior according to the first unit oxygen supply amount.

[0096] The first unit oxygen supply amount refers to the amount of oxygen input into the vehicle interior per unit time. In this example, the first unit oxygen supply amount can be controlled by controlling at least one of the oxygen supply speed, oxygen supply concentration, and oxygen supply flow rate. Taking the oxygen generation device including a compressor and a molecular sieve as an example in this example, the first unit oxygen supply amount can be controlled by adjusting at least one of the rotation speed of the compressor and the working time of the molecular sieve.

[0097] S140: Determine whether the real-time oxygen supply signal reaches the preset oxygen supply value. If so, supply oxygen to the vehicle interior according to the second unit oxygen supply amount, where the first unit oxygen supply amount is greater than the second unit oxygen supply amount.

[0098] When the real-time oxygen supply signal reaches the preset oxygen supply value, it indicates that the oxygen supply in the vehicle can meet the demand at this time. At this time, the amount of oxygen input into the vehicle interior can be reduced. The second unit oxygen supply amount is less than the first unit oxygen supply amount to reduce the amount of oxygen input into the vehicle interior at this time. In this example, when it is determined that the oxygen supply condition is reached according to the real-time oxygen supply signal, oxygen can be supplied to the vehicle interior at the maximum unit oxygen supply amount. When the oxygen supply in the vehicle interior meets the demand, a small amount of oxygen is continuously replenished into the vehicle interior to balance the oxygen consumption in the vehicle interior.

[0099] In some examples, after the above step S140, in order to keep the oxygen in the vehicle interior in a relatively balanced state, the method of supplying oxygen to the vehicle interior further includes adjusting the second unit oxygen supply amount so that the real-time oxygen supply signal in the vehicle interior is not less than the preset oxygen supply value. In this example, the second unit oxygen supply amount can be dynamically adjusted to compensate for the oxygen consumption in the vehicle interior, and thus the oxygen in the vehicle interior can be kept in dynamic balance. In this example, the second unit oxygen supply amount can be dynamically adjusted according to at least one of signals such as the oxygen concentration in the vehicle interior, the vehicle altitude, and the blood oxygen concentration of the passengers. Among them, the method of adjusting the second unit oxygen supply amount includes adjusting at least one of the oxygen supply speed, oxygen supply concentration, and oxygen supply flow rate to the vehicle interior. Taking the above compressor and molecular sieve as an example, in this example, the second unit oxygen supply amount can be adjusted by dynamically adjusting parameters such as the rotation speed of the compressor and the working duration of the molecular sieve.

[0100] In some examples, the generated high-concentration oxygen can be temporarily stored. Then, when the real-time oxygen supply signal in the vehicle 100 is lower than the preset oxygen supply value, the high-concentration oxygen can be temporarily stored. When the real-time oxygen supply signal in the vehicle 100 exceeds the preset oxygen supply value, the high-concentration oxygen is timely input into the vehicle 100. Thus, the generated high-concentration oxygen can play a role in peak shaving and valley filling, and the generated high-concentration oxygen can have a higher utilization rate.

[0101] In some examples, in step S100, the first air source outside the vehicle 100 can be inhaled by means of negative pressure. By pressurizing the first air source, the subsequent processing efficiency can be improved. In this example, the first air source can be pressurized by a compressor 2321 or other equipment capable of pressurizing gases. By reducing the concentration of gases other than oxygen in the pressurized first air source, high-concentration oxygen is generated, and the oxygen concentration of the high-concentration oxygen is greater than that of the first air source. Since the main component of air is nitrogen, in this example, it can be mainly used to reduce the concentration of nitrogen in the air. After the concentration of gases other than oxygen in the first air source is reduced, the oxygen concentration in the generated high-concentration oxygen is higher than that in the first air source. After the high-concentration oxygen is input into the vehicle 100, the oxygen concentration inside the vehicle 100 will increase, and thus the oxygen supply inside the vehicle 100 can be improved.

[0102] In some examples, the first air source can also be filtered. In this example, the impurity content in the first air source can be reduced by filtration to reduce the impact of impurities on the air quality inside the vehicle 100.

[0103] In some examples, before the high-concentration oxygen is input into the vehicle interior, the temperature of the high-concentration oxygen can also be reduced by means of heat exchange or the like. By reducing the temperature of the high-concentration oxygen, the impact of high temperature on the subsequent oxygen generation process can be reduced, and the removal rate of gases other than oxygen in the air can be improved.

[0104] Please refer to Figure 5 , in some examples, in step S200, processing the carbon dioxide inside the vehicle includes the following steps:

[0105] S210: Input a target gas into the vehicle interior, where the carbon dioxide concentration of the target gas is less than a preset carbon dioxide concentration.

[0106] The target gas is a gas with a relatively low carbon dioxide concentration. In this example, the carbon dioxide concentration of the target gas is less than the preset carbon dioxide concentration, so that the target gas input into the vehicle interior can play the role of reducing the carbon dioxide concentration inside the vehicle.

[0107] S220: Obtain the carbon dioxide concentration of the target gas, and determine whether the difference between the preset carbon dioxide concentration and the carbon dioxide concentration of the target gas reaches a second preset range. If so, stop the step of inputting the preset gas into the vehicle interior.

[0108] In this example, the carbon dioxide concentration of the target gas input into the vehicle interior can be detected, and then it can be determined whether the target gas input into the current system can improve the air composition inside the vehicle. The second preset range is the difference between the preset carbon dioxide concentration and the carbon dioxide concentration of the target gas. When the carbon dioxide concentration of the target gas is equal to or close to the preset carbon dioxide concentration, the influence of the target gas input into the vehicle interior on the air composition inside the vehicle decreases. At this time, the input of the target gas into the vehicle interior can be stopped. In this example, physical or chemical methods can be used to reduce the carbon dioxide concentration in the air. When the carbon dioxide concentration of the target gas generated by the device is close to or equal to the preset carbon dioxide concentration, it indicates that the carbon dioxide processing capacity of the current device may have reached its limit. At this time, the step of inputting the target gas into the vehicle interior can be stopped to update the device in a timely manner.

[0109] In the above step S210, the second air source inside the vehicle 100 can be inhaled. In this example, the second air source can be inhaled by means of negative pressure. The second air source is pressurized to improve the processing efficiency of the second air source and increase the carbon dioxide processing efficiency. In this example, a booster pump or other equipment that can be used to form high-pressure gas from the second air source can be used. The carbon dioxide concentration in the pressurized second air source is reduced to generate a target gas, and the carbon dioxide concentration of the target gas is less than that of the second air source. By reducing the carbon dioxide concentration in the second air source, the carbon dioxide concentration of the target gas can be made less than that of the second air source. Then, when the second air source is input into the vehicle 100 interior, the carbon dioxide concentration inside the vehicle 100 can be reduced. In this example, the target gas can be input into one or more places inside the vehicle 100 to reduce the carbon dioxide concentration inside the vehicle 100 and improve the comfort of the air inside the vehicle 100.

[0110] In some examples, in step S200, the method for treating carbon dioxide inside the vehicle 100 further includes filtering the second air source. In this example, the second air source can be filtered by devices such as filters to reduce the impurities in the second air source, reduce the influence of the impurities on the device, and improve the processing efficiency of the second air source.

[0111] In some examples, in step S200, the method for treating carbon dioxide inside the vehicle 100 further includes pressurizing the target gas. In this example, devices such as a vacuum pump 2337 can be used to pressurize and output the target gas to improve the output efficiency of the target gas.

[0112] Please refer to Figure 6, this application presents an example of an in-vehicle air treatment system 200 that can be used in a vehicle 100. The in-vehicle air treatment system 200 includes a detection component 210, an oxygen generation device 232, and a carbon dioxide treatment device 233. The detection component 210 is used to detect the oxygen supply signal of the vehicle 100 and the carbon dioxide concentration inside the vehicle 100; the oxygen generation device 232 is electrically connected to the detection component 210 and is used to supply oxygen to the inside of the vehicle 100; the carbon dioxide treatment device 233 is electrically connected to the detection component 210 and is used to treat the carbon dioxide inside the vehicle 100.

[0113] The oxygen generation device 232 and the carbon dioxide treatment device 233 can be installed at preset positions on the vehicle 100. The oxygen generation device 232 and the carbon dioxide treatment device 233 are used to treat air to generate high-concentration oxygen or target gas, and then input it into the vehicle 100 through an air outlet 234 connected to the inside of the vehicle 100. In the example of this application, the air outlet 234 can be set at any position inside the vehicle 100. Optionally, the number of the air outlets 234 can be multiple, and the multiple air outlets 234 can be distributed at different positions inside the vehicle 100. The oxygen generation device 232 and the carbon dioxide treatment device 233 in this example can each have an air inlet, and the air inlet can be used to connect to any position on the vehicle 100. Optionally, the air inlets of the oxygen generation device 232 and the carbon dioxide treatment device 233 can be respectively connected to the inside and outside of the vehicle 100. The oxygen generation device 232 and the carbon dioxide treatment device 233 in this example can be independently installed at preset positions inside the vehicle 100. Optionally, the oxygen generation device 232 and the carbon dioxide treatment device 233 can also be integrated with other functional modules on the vehicle 100 to improve the space utilization rate of the vehicle 100.

[0114] The detection component 210 can be used to detect the oxygen supply signal of the vehicle 100 and the carbon dioxide concentration inside the vehicle 100; in the example of this application, the working states of the oxygen generation device 232 and the carbon dioxide treatment device 233 can be determined according to the signals detected in real time by the detection component 210, so that the working states of the oxygen generation device 232 and the carbon dioxide treatment device 233 are adapted to the air state inside the vehicle 100. Taking the oxygen content as an example, when the first difference between the oxygen content inside the vehicle 100 and the preset oxygen supply value is large, the processing efficiency of the oxygen generation device 232 can be increased to increase the output oxygen volume of the oxygen generation device 232, thereby quickly increasing the oxygen content inside the vehicle 100; when the oxygen content inside the vehicle 100 reaches the preset value, the processing efficiency of the oxygen generation device 232 can be reduced to reduce the power consumption of the oxygen generation device 232. In this example, the oxygen generation device 232 is set to an adjustable state, and the working states of the oxygen generation device 232 and the carbon dioxide treatment device 233 can be adjusted in real time according to the oxygen supply signal and / or carbon dioxide concentration signal detected by the detection component 210 for quick adjustment. After the air inside the vehicle 100 reaches a certain state, dynamic adjustment can be carried out. By reducing the pressure values of the oxygen generation device 232 and the carbon dioxide treatment device 233, etc., the output volume of the processed air can be reduced, and then trickle output can be carried out to maintain the air state inside the vehicle with a smaller pressure value and reduce energy consumption; when the environment changes, automatic closed-loop can be carried out through the above data for intelligent control.

[0115] In some examples, the oxygen supply signal includes the biological signal of the passengers inside the vehicle 100, and the detection component 210 is a blood oxygen concentration sensor 212. The biological signal can be regarded as a reaction of the passenger's own state. The detection component 210 can be used to detect the blood oxygen concentration of the passenger to determine whether the current passenger needs to supplement oxygen according to the blood oxygen concentration. The blood oxygen concentration sensor 212 in this example can be a terminal independently set inside the vehicle 100 that detects the user's biological signal by sound, light, electricity or other means. For example, the detection component 210 can be set in the shape of a specific part that can be worn on the user's body. When the user wears the detection component 210 on the body, the detection component 210 can obtain the current biological signal of the user in real time. Optionally, the detection component 210 is connected to a wearable device worn on the user, such as a smart bracelet, a smart watch, a smart ring or other wearable devices that can be used to obtain the biological signal of the wearer, and the oxygen supply signal value can be determined by reading the biological signal on the wearable device, and then the air treatment component can be controlled to work.

[0116] In some examples, the oxygen supply signal includes the altitude signal of vehicle 100, and the detection component 210 is the altitude detection sensor 213; the altitude detection sensor 213 can be used to obtain the current altitude signal of vehicle 100. As the altitude of vehicle 100 increases, the oxygen content in vehicle 100 can decrease accordingly. Therefore, the altitude signal of vehicle 100 can be obtained, and the working state of the oxygen generation device 232 can be controlled according to the altitude signal of vehicle 100. When the altitude where vehicle 100 is located is relatively high, the oxygen output of the oxygen generation device 232 can be increased; when the altitude where vehicle 100 is located is relatively low, the oxygen output of the oxygen generation device 232 can be appropriately reduced.

[0117] In some examples, the carbon dioxide concentration signal includes the biological signal of the passengers inside vehicle 100, and the detection component 210 is the blood carbon dioxide concentration detection sensor 215. The biological signal can be regarded as a reaction of the passengers' own state. The detection component 210 can be used to detect the blood carbon dioxide concentration of the passengers to determine whether the current passengers need to supplement oxygen according to the blood carbon dioxide concentration. The carbon dioxide detection device in this example can be a terminal independently set inside vehicle 100 that detects the biological signal of the user by sound, light, electricity or other means. Optionally, the detection component 210 can be connected to a wearable device worn on the user, for example, a smart bracelet, a smart watch, a smart ring or other wearable devices that can be used to obtain the biological signal of the wearer.

[0118] Please refer to Figure 7 , in some examples, the oxygen generation device 232 is provided with a first air inlet 2311 and an oxygen outlet 7e. The oxygen outlet 7e is used to communicate with the inside of vehicle 100; the oxygen generation device 232 includes a compressor 2321 and an oxygen generation component 2322. The compressor 2321 is connected between the first air inlet 2311 and the oxygen generation component 2322, and the oxygen generation component 2322 is communicated with the oxygen outlet 7e.

[0122] In some examples, the oxygen generation component 2322 is a molecular sieve; the molecular sieve can be used to reduce the content of gases such as nitrogen in the high-pressure gas to form high-concentration oxygen. The molecular sieve in this example can generate high-concentration oxygen by adsorption or separation methods. The molecular sieve can selectively adsorb specific gases based on the differences in its adsorption properties for different gas molecules, according to the characteristics of the molecules such as size, shape, and polarity, allowing other gas molecules to pass through. Through the adsorption and desorption processes, high-purity oxygen is finally obtained. The molecular sieve is a material with a microporous structure, usually synthesized from zeolite minerals. Common molecular sieve raw materials include natural zeolites and synthetic zeolites, and their main component is aluminosilicate. By adjusting the silicon-aluminum ratio and introducing different cations, molecular sieves with different pore sizes and adsorption characteristics can be prepared. The pore size and surface characteristics of the molecular sieve are the reasons for its selective adsorption of gas molecules.

[0123] In some examples, the oxygen generation device 232 further includes an intake control valve 2325 and a first outlet control valve 2326. The intake control valve 2325 is connected between the inlet of the molecular sieve and the outlet of the compressor 2321 to control the intake air volume of the molecular sieve; the first outlet control valve 2326 is connected to the outlet of the molecular sieve to control the outlet air volume of the molecular sieve.

[0132] The second air inlet 2312 can communicate with the interior of the vehicle 100. The carbon dioxide treatment device 233 is used to treat the air to reduce the content of carbon dioxide in the air, and then the air flows back into the vehicle 100. Through the cyclic treatment of the carbon dioxide treatment device 233, the carbon dioxide content inside the vehicle 100 can be reduced.

[0133] In this example, the number of the second air inlets 2312 can be multiple, and the multiple second air inlets 2312 can be distributed at intervals on the vehicle 100. The carbon dioxide treatment device 233 can be integrated on the electrical equipment of the vehicle 100. In some examples, the oxygen generation device 232 can be integrally arranged with the carbon dioxide treatment device 233, or the oxygen generation device 232 and the carbon dioxide treatment device 233 can be respectively installed at different positions on the vehicle 100. The carbon dioxide treatment device 233 in this example can treat the carbon dioxide in the air by physical separation or chemical treatment. In this example, by cyclically treating the air inside the vehicle 100, the carbon dioxide concentration inside the vehicle 100 can be reduced, and the health hazards caused by excessive carbon dioxide concentration can be reduced.

[0134] In this example, the carbon dioxide concentration signal can be obtained in real time, and the carbon dioxide treatment device 233 can be controlled to work according to the carbon dioxide concentration signal, so that the operating state of the carbon dioxide treatment device 233 is adapted to the air state inside the vehicle 100.

In some examples, the carbon dioxide adsorption assembly 2332 further includes a first heating member 2333a connected to the adsorption tower 2333 for heating the adsorption tower 2333.

[0137] The air suction member 2331 is used to pressurize the air input from the second air inlet 2312.

In this example, the adsorption tower 2333 can use physical or chemical methods to reduce the carbon dioxide content in the air. The processed gas is output to the interior of the vehicle 100 via the air outlet 234. The adsorption tower 2333 in this example can share the same air outlet 234 with the oxygen generation device 232 in any of the above examples. In this example, an electrical signal can be sent to the air suction member 2331 and the adsorption tower 2333 to control the operation of either the air suction member 2331 or the adsorption tower 2333. In this example, when the carbon dioxide concentration signal changes, the processing efficiency of the carbon dioxide treatment device 233 can be adjusted by adjusting the pressure value of the air suction member 2331 or the working state of the adsorption tower 2333.

[0138] The first heating member 2333a can be used to heat the adsorption tower 2333. When it is detected that the carbon dioxide concentration in the vehicle 100 exceeds the safety value, the adsorption tower 2333 and the air suction member 2331 can be controlled to start. The air suction member 2331 delivers the high-concentration carbon dioxide gas in the vehicle to the adsorption tower 2333. After the adsorption tower 2333 adsorbs the carbon dioxide gas, the carbon dioxide concentration of the discharged gas can be controlled at about 0.04%, which is basically the same as the carbon dioxide concentration in natural air. The adsorbed adsorption tower 2333 can be heated to a certain temperature (80 - 300 °C) by the heating module, and finally the gas containing high-concentration carbon dioxide desorbed is discharged by means of vacuum pumping (the vacuum degree is -50 - 99 kPa). After the desorbed adsorption tower 2333 cools down, it can be recycled. In this example, the desorption time of the adsorption tower 2333 can be controlled by controlling the working time and temperature of the heating module. At the same time, the air suction member 2331 can also be controlled to work, and the air inside the vehicle 100 can be processed by combining temperature swing adsorption and pressure swing adsorption.

[0140] In some examples, the carbon dioxide adsorption component 2332 includes a zeolite rotor 2334, a second heating element 2335, a desorption fan 2339 and a rotating motor 2338. The zeolite rotor 2334 is used to adsorb carbon dioxide.

[0141] The zeolite wheel 2334 can be used to adsorb carbon dioxide in the air. By circulating air into the carbon dioxide adsorption mechanism, the gas inside the vehicle 100 can be circulated and purified to reduce the carbon dioxide content inside the vehicle 100.

[0142] In some examples, the zeolite rotor 2334 includes an adsorption zone 2334b, a cooling zone 2334a and a desorption zone 2334c. The detection component 210 detects the carbon dioxide concentration of the vehicle 100. When it is determined that the vehicle 100 contains a high concentration of carbon dioxide gas, the suction member 2331 forms a negative pressure at the second air inlet 2312, and the air in the vehicle is adsorbed into the adsorption zone 2334b of the zeolite rotor 2334. After the molecular sieve in the adsorption zone 2334b adsorbs the carbon dioxide gas, the carbon dioxide concentration of the discharged gas can be controlled to about 0.04%, which is basically the same as the carbon dioxide concentration in natural air; after the molecular sieve in the adsorption zone 2334b is saturated with adsorption, it is transferred to the desorption zone 2334c by the rotating motor 2338, and the gas is output to the heating module by the desorption extension. The hot air generated after heat exchange can be transported to the desorption zone 2334c, and the molecular sieve area where desorption is completed is transferred to the cooling zone 2334a, and the cooled molecular sieve can be recycled.

[0143] The number of carbon dioxide adsorption mechanisms is multiple, and the multiple carbon dioxide adsorption mechanisms are arranged in parallel between the outlet of the air suction member 2331 and the air outlet 234; the carbon dioxide treatment device 233 further includes a third air outlet control valve 2336, and the third air outlet control valve 2336 is arranged between the outlets of the multiple carbon dioxide adsorption mechanisms and the air outlet 234, and the third air outlet control valve 2336 is used to control the flow rate of the output air of the multiple carbon dioxide adsorption mechanisms; in this example, the multiple carbon dioxide adsorption mechanisms can work simultaneously, or the multiple carbon dioxide adsorption mechanisms can work with staggered peaks. In this example, the air treatment efficiency of the carbon dioxide treatment device 233 can be controlled by controlling the working time of the multiple carbon dioxide adsorption mechanisms.

[0144] In some examples, the carbon dioxide treatment device 233 further includes a second filtering structure 8a, and the second filtering structure 8a is arranged between the second air inlet 2312 and the inlet of the air suction member 2331 for filtering the air entering the air suction member 2331.
