[0075] Now, exemplary embodiments according to the present disclosure will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0076] like Figures 1 to 5 As shown, the embodiment of the present disclosure provides an atmosphere-controlled device 100, a fresh-keeping device 200 and a control method thereof, a storage medium, and an electronic device. The atmosphere-controlled device 100 is applied to the fresh-keeping device 200, and the fresh-keeping device 200 can be a refrigerator, a cold chain transport vehicle, a fresh-keeping box, a fresh-keeping bag, etc. The fresh-keeping device 200 is used to preserve objects to be preserved. The atmosphere-controlled device 100 is connected to an atmosphere-controlled area 210 containing objects to be preserved, so as to increase the preservation time of the objects to be preserved contained in the atmosphere-controlled area 210.

[0077] Research has found that the temperature and gas composition of the atmosphere-controlled zone 210 have an impact on the shelf life of the items to be preserved. As for the impact of temperature, people usually choose refrigerators with refrigeration capabilities, cold chain transportation equipment, etc. to achieve the storage of objects to be preserved. However, since different types of objects to be preserved have different requirements for preservation temperatures, simple low temperatures are actually limited in their effect on extending the shelf life of fresh food. To this end, the embodiment of the present disclosure provides an atmosphere-controlled device 100, which is used to adjust the gas composition of the atmosphere-controlled zone 210 to increase the shelf life of the objects to be preserved contained in the atmosphere-controlled zone 210.

[0078] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present disclosure provides an atmosphere-conditioning device 100 for a fresh-keeping device 200, the atmosphere-conditioning device 100 comprising: at least one adsorption module 110, the adsorption module 110 is connected to an air inlet 212 of an atmosphere-conditioning zone 210 of the fresh-keeping device 200, the air pressure inside or downstream of the adsorption module 110 is a first air pressure, and the air pressure inside the atmosphere-conditioning zone 210 is a second air pressure; an air outlet of a fluid driving device 130 is connected to the adsorption module 110; an air inlet of the fluid driving device 130 is connected to an air outlet 211 of the atmosphere-conditioning zone 210, a control device, a fluid driving device and a control device are connected, and the control device is configured to control the fluid driving device so that the first air pressure is higher than the second air pressure.

[0079] Among them, the adsorption module 110 is configured to separate preset components in the gas flowing through it. It can be understood that the preset components can be oxygen, nitrogen, carbon dioxide, etc. Taking the preset component as nitrogen as an example, when the gas flows through the adsorption module 110, the nitrogen in the gas can be separated.

[0080] The controlled atmosphere zone 210 is provided with an air inlet 212 and an air outlet 211 to realize the circulation of the air flow in the controlled atmosphere zone 210 and the external air flow.

[0081] like Figure 1 and Figure 2 As shown, in the gas-conditioning device 100 provided by the embodiment of the present disclosure, the gas outlet 211 of the gas-conditioning zone 210, the second valve assembly 140, the fluid driving device 130, at least one adsorption module 110, the first valve assembly 120, and the gas inlet 212 of the gas-conditioning zone 210 are connected in sequence, and the sequential connection includes but is not limited to direct connection. The air pressure inside or downstream of the adsorption module 110 is the first air pressure, and the air pressure in the gas-conditioning zone 210 is the second air pressure. Therefore, by reasonably adjusting the fluid driving device 130 or other gas boosting devices, etc., the first air pressure is made higher than the second air pressure. In this way, the air outlet 211 of the atmosphere-controlled zone 210, the fluid driving device 130, at least one adsorption module 110, and the air inlet 212 of the atmosphere-controlled zone 210 form a circulating airflow passage, and can ensure that the gas in the atmosphere-controlled zone 210 is separated into airflows of preset components by the adsorption module 110 and then returned to the atmosphere-controlled zone 210. Therefore, the gas components of the atmosphere-controlled zone 210 can be adjusted, so that the adjusted gas components of the atmosphere-controlled zone 210 are conducive to extending the preservation time of the objects to be preserved and improving the preservation quality of the objects to be preserved. At the same time, since the gas flowing through the adsorption module 110 comes from the gas conditioning zone 210, and the gas of preset components separated by the adsorption module 110 also flows to the gas conditioning zone 210, that is, the adsorption module 110 separates the gas from the gas conditioning zone 210 into gas conditioning of preset components and then returns it to the gas conditioning zone 210, the adsorption module 110 realizes the capture and release of the gas, and uses the gas of the gas conditioning zone 210 itself to directly adjust the gas components in the gas conditioning zone 210, which greatly improves the utilization rate of the gas in the gas conditioning zone 210 and reduces the waste of gas energy.

[0082] The fluid driving device 130 or other gas boosting device is connected to the control device, and the control device is configured to control the fluid driving device 130 or other gas boosting device so that the first air pressure is higher than the second air pressure. The fluid driving device 130 may be an air compressor or an air pump. The control device adjusts the working state of the fluid driving device 130 or other gas boosting device to ensure that the gas pressure flowing out of the adsorption module 110 is higher than the gas pressure of the gas conditioning zone 210, thereby ensuring that the airflow of the preset components separated by the adsorption module 110 can flow smoothly and reliably into the gas conditioning zone 210 to adjust the gas components of the gas conditioning zone 210.

[0083] The number of adsorption modules 110 can be one, two, three or other numbers to achieve separation of gases of different preset components, so that gases of different preset components flow into the gas conditioning zone 210 to achieve adjustment of different gas components in the gas conditioning zone 210, so as to extend the preservation time of different types of objects to be preserved and expand the scope of use. When the number of adsorption modules 110 is at least two, at least two adsorption modules 110 can separate different preset components in the gas. At this time, the first valve assembly 120 can be a multi-way valve, so that the first valve assembly 120 can be controlled to connect one adsorption module 110 with the air inlet 212 according to the type of object to be preserved, so as to adjust the gas components in the gas conditioning zone 210 through the gas of the preset components separated by the adsorption module 110, or the first valve assembly 120 can be controlled to connect two or more adsorption modules 110 with the air inlet 212, so as to adjust the gas components in the gas conditioning zone 210 through two or more gases of preset components.

[0084] Specifically, when the number of adsorption modules 110 is at least two and at least two gas components in the gas conditioning zone 210 need to be adjusted, one adsorption module 110 can be used in turn to adjust the corresponding gas components, and then another adsorption module 110 can be controlled to adjust the corresponding gas components, and so on, at least two adsorption modules 110 can be used to adjust at least two gas components so that the gas components in the gas conditioning zone 210 meet the target information.

[0085] Furthermore, the fluid driving device 130 is connected to the air outlet of the gas conditioning zone 210 through the second valve assembly 140, and the second valve assembly 140 is connected to the control device. The adsorption module 110 is connected to the air inlet of the gas conditioning zone 210 of the fresh-keeping device through the first valve assembly 120, and the first valve assembly 120 is connected to the control device.

[0086] The gas conditioning device 100 may further include a filter 191, which is disposed between the second valve assembly 140 and the fluid driving device 130 to filter the gas entering the fluid driving device 130 through the second valve assembly 140, so as to reduce the influence of impurities on the reliability of the fluid driving device 130 and various components downstream of the fluid driving device, and improve the service life and reliability of the fluid driving device 130 and various components downstream of the fluid driving device.

[0087] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the second valve assembly 140 is a multi-way valve, the second valve assembly 140 is also connected to the external environment, and the control device is also configured to adjust the connection and disconnection between the fluid driving device 130 and the gas conditioning zone 210, and / or the connection and disconnection between the fluid driving device 130 and the external environment through the second valve assembly 140.

[0088] That is to say, the gas flowing into the adsorption module 110 through the fluid driving device 130 can be the gas of the external environment, or the gas in the gas-controlled zone 210, or it can also be the common gas of the external environment and the gas-controlled zone 210. Therefore, according to the target component information of the gas ultimately required in the gas-controlled zone 210, the on-off state of the fluid driving device 130 and the gas-controlled zone 210, and the on-off state of the fluid driving device 130 and the external environment can be reasonably selected, so that a relatively sufficient gas flow with a relatively reasonable gas composition can flow into the adsorption module 110 through the fluid driving device 130, separate, and then flow into the gas-controlled zone 210 again, so that the gas in the gas-controlled zone 210 can quickly reach the target component, and the adjustment of the gas-controlled component in the gas-controlled zone 210 can be quickly realized.

[0089] In some possible embodiments provided by the present disclosure, the atmosphere control device 100 also includes: an exhaust device 150, which is connected to the second valve assembly 140, and the control device is also configured to adjust the connection and disconnection between the atmosphere control zone 210 and the exhaust device 150 through the second valve assembly 140.

[0090] The exhaust device 150 is connected to the external environment. The exhaust device 150 can exhaust the gas in the gas conditioning area 210 to the external environment. Specifically, when the second valve assembly 140 connects the fluid driving device 130 with the external environment, the first valve assembly 120 connects at least one adsorption module 110 with the air inlet 212 of the gas-controlled zone 210, that is, the gas in the external environment flows into the gas-controlled zone 210 after passing through the fluid driving device 130 and the adsorption module 110. In this state, if the airflow in the gas-controlled zone 210 is closed, it will affect the level of the second air pressure. Therefore, the air outlet 211 of the gas-controlled zone 210 is connected to the exhaust device 150 through the second valve assembly 140, so that the gas in the gas-controlled zone 210 is discharged from the exhaust device 150 to the external environment through the air outlet 211, thereby enabling the airflow to form a circulation passage, so that the gas in the gas-controlled zone 210 can be discharged smoothly, so as to improve the regulation efficiency of the gas components in the gas-controlled zone 210, and at the same time, the gas separated by the adsorption module 110 can flow smoothly into the gas-controlled zone 210. In some other embodiments, the exhaust device 150 may not be provided, and the gas in the gas conditioning zone 210 is directly discharged into the environment through the gas outlet 211 .

[0091] In the above embodiment, the exhaust device 150 is also provided with a silencer, which can reduce the noise of the gas discharged to the external environment through the exhaust device 150, reduce the impact of the noise on the user, and improve the comfort of use. Specifically, the silencer can be a silencer cotton.

[0092] Alternatively, the exhaust device 150 is made of a sound-absorbing material to reduce the noise of the gas being discharged to the external environment through the exhaust device 150 .

[0093] Alternatively, the exhaust device 150 is provided with a silencer structure, such as a silencer hole, a silencer gap, etc., to reduce the noise of the gas discharged to the external environment through the exhaust device 150.

[0094] Specifically, the exhaust device 150 may include an exhaust nozzle, in which sound-absorbing cotton is arranged, or a sound-absorbing gap is arranged on the exhaust nozzle, or the exhaust nozzle is made of sound-absorbing material.

[0095] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, a third valve assembly 160 is also connected between the fluid driving device 130 and the adsorption module 110, and the control device is connected to the third valve assembly 160 to adjust the on / off state of at least one adsorption module 110 and the fluid driving device 130.

[0096] The setting of the third valve assembly 160 allows the fluid drive device 130 to be selectively and specifically connected to each adsorption module 110, so that the gas can be separated into the required preset components through the corresponding adsorption module 110, so as to improve the accuracy and efficiency of gas component regulation in the gas conditioning zone 210.

[0097] For example, when the gas conditioning zone 210 needs to increase the nitrogen ratio, at this time, the fluid driving device 130 can be connected to the adsorption module 110 that can separate nitrogen through the third valve assembly 160, and the fluid driving device 130 can be isolated from other adsorption modules 110, so that the gas flowing through the fluid driving device 130 can flow through the adsorption module 110 that separates nitrogen in whole or in large part, thereby increasing the amount of nitrogen separated by the adsorption module 110, that is, the nitrogen separated by the adsorption module 110 can fully flow into the gas conditioning zone 210, so that the nitrogen ratio in the gas components of the gas conditioning zone 210 quickly reaches the preset requirements, so as to improve the adjustment efficiency and accuracy of the gas conditioning components of the gas conditioning zone 210. It can be understood that when the gas conditioning zone 210 needs to increase the gas ratio of the two components, the fluid driving device 130 is connected to the adsorption modules 110 of the two components in sequence through the third valve assembly 160, which can also achieve the effect of quickly adjusting the gas components of the gas conditioning zone 210.

[0098] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the third valve assembly 160 is also connected to the exhaust device 150, and the control device is also configured to adjust the connection and disconnection between the fluid driving device 130 and the exhaust device 150, and / or the connection and disconnection between the adsorption module 110 and the exhaust device 150 through the third valve assembly 160.

[0099] Among them, the third valve assembly 160 connects the fluid driving device 130 with the exhaust device 150, so that when the fluid driving device 130 is connected with the gas outlet 211 of the gas-controlled zone 210, the gas in the gas-controlled zone 210 can be discharged by the exhaust device 150 after passing through the fluid driving device 130, so as to ensure that the first air pressure is higher than the second air pressure. In some embodiments, the fluid driving device 130 can be an air compressor, so that the gas in the gas-controlled zone 210 can be pumped out through the gas outlet 211 by the air compressor, so that the gas-controlled zone 210 can be in a negative pressure state. Further, when the first valve assembly 120 is in a closed state, that is, the gas inlet 212 of the gas-controlled zone 210 is in a closed state, the gas-controlled zone 210 is sucked out by the fluid driving device 130, so that the gas-controlled zone 210 can be in a vacuum state, so as to meet the requirement of extending the preservation time of the object to be preserved in a vacuum state, and further expand the scope of use of the gas-controlled device 100.

[0100] The third valve assembly 160 connects the adsorption module 110 and the exhaust device 150 , so that after the adsorption module 110 separates the gas of preset components, the remaining excess gas can be discharged through the exhaust device 150 .

[0101] In some possible embodiments provided by the present disclosure, the control device is also configured to control the second gas pressure to normal pressure or negative pressure through the fluid driving device 130, thereby ensuring that the first gas pressure is higher than the second gas pressure, so that the gas of preset components separated by the adsorption module 110 can flow smoothly into the gas conditioning zone 210.

[0102] In one example, the control device is configured to control the second valve assembly 140 to connect the gas outlet 211 of the gas-controlled zone 210 with the exhaust device 150. The control device also controls the second valve assembly 140 to connect the fluid drive device 130 with the external environment, the third valve assembly 160 to connect the fluid drive device 130 with at least one adsorption module 110, and the first valve assembly 120 to connect the adsorption module 110 with the gas inlet 212 of the gas-controlled zone 210. Thus, the external environment, the adsorption module 110 and the gas-controlled zone 210 constitute an airflow circulation system, which can keep the second air pressure at normal pressure, ensure that the preset component airflow separated by the adsorption module 110 can smoothly enter the gas-controlled zone 210, and the separated waste gas can be released into the environment through the exhaust device 150. Among them, normal pressure can be understood as one atmospheric pressure.

[0103] In another example, the control device is configured to control the second valve assembly 140 to connect the gas-controlled zone 210 and the fluid drive device 130, and control the third valve assembly 160 to connect the fluid drive device 130 and the adsorption module 110, and connect the adsorption module 110 and the exhaust device 150, so that the gas in the gas-controlled zone 210 is separated by the adsorption module 110 through the fluid drive device 130 and then discharged, such as returning to the gas-controlled zone 210, and the remaining gas after the separation by the adsorption module 110 is discharged through the exhaust device 150, so that the second air pressure maintains a negative pressure, and the first air pressure is higher than the second air pressure, to ensure that the preset component airflow after separation by the adsorption module 110 can smoothly enter the gas-controlled zone 210.

[0104] In another example, the control device is configured to control the second valve assembly 140 to connect the gas-controlled zone 210 with the fluid drive device 130, and control the third valve assembly 160 to connect the fluid drive device 130 with the exhaust device 150, so that the gas in the gas-controlled zone 210 passes through the fluid drive device 130 and then is discharged through the exhaust device 150, so that the second air pressure remains negative. In some embodiments, the fluid drive device 130 includes but is not limited to an air compressor. At this time, the air inlet of the gas-controlled zone 210 and the adsorption module 110 can be controlled by the first valve assembly 120 to be in a blocked state, that is, the air inlet is closed, so that the gas in the gas-controlled zone 210 is sucked by the fluid drive device 130 and then discharged through the exhaust device 150, so that the gas-controlled zone 210 can be in a vacuum state.

[0105] In some possible embodiments provided by the present disclosure, the adsorption module 110 includes an adsorption material, which is configured to separate preset components in the gas flowing through it to achieve the function of separating gas components. In some embodiments, an adsorption channel is also included, which is connected to the fluid driving device 130 and the air inlet of the gas conditioning zone 210. Further, the adsorption material is arranged inside the adsorption channel or communicated with the adsorption channel.

[0106] Furthermore, the working form of the adsorption module 110 can be to use high-porosity adsorption materials for adsorption and desorption, or to use the difference in molecular kinetic diameter between gas molecules and molecular sieve membranes made of adsorption materials to achieve separation. For example, the adsorption module 110 can change the porosity of the adsorption material by applying an electric field (such as adjusting the size of the filtered molecules to distinguish between nitrogen and oxygen). Then this type of adsorption module 110 can change its physical and chemical properties through external means, so that molecular sieves with different porosities can achieve gas separation of different components.

[0107] Among them, the adsorption material can be zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to zeolite molecular sieve, A / X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), phosphorus aluminum molecular sieve, a class of mesoporous composite molecular sieves, etc. Among them, the molecular sieve can be a silicon framework mesoporous molecular sieve with the material of SBA-15, and suitable metal ions can be embedded as needed to improve the performance of molecular sieve deintercalation and filtering gas molecules.

[0108] The adsorbent material is set to be desorbable when the desorption temperature is reached, or the adsorbent material is set to be desorbable when the desorption pressure is reached. In other words, the adsorbent material can be a temperature-controlled adsorption-desorption type or a pressure swing adsorption-desorption type.

[0109] Among them, the temperature-controlled adsorption-desorption type adsorption material, when the temperature of the air flow flowing through the adsorption material is lower than the desorption temperature, the adsorption material adsorbs gases of other components to separate gases of preset components. When the temperature of the air flow flowing through the adsorption material reaches the desorption temperature, gases of other components adsorbed by the adsorption material will be desorbed, and the gases of preset components cannot be separated.

[0110] Among them, the pressure swing adsorption desorption type adsorption material can use zeolite molecular sieve as an adsorbent, and use the principle of pressurized adsorption and reduced pressure desorption to adsorb and release nitrogen from the air, thereby separating oxygen. Zeolite molecular sieve is a spherical granular adsorbent that is processed through a special pore treatment process and is covered with micropores on the surface and inside. It is white. Its pore characteristics enable it to achieve the kinetic separation of O2 and N2. The separation effect of zeolite molecular sieve on O2 and N2 is based on the slight difference in the kinetic diameters of the two gases. N2 molecules have a faster diffusion rate in the micropores of zeolite molecular sieves, while O2 molecules have a slower diffusion rate. The diffusion of water and CO2 in compressed air is not much different from that of nitrogen. Ultimately, the gas flowing through the adsorption material will be separated into oxygen molecules with a concentration of more than 93% ± 3%.

[0111] In some possible embodiments provided by the present disclosure, each adsorption module 110 is separately provided; or at least part of the adsorption modules 110 are integrated in the adsorption tower, and at least part of the adsorption channels in the adsorption tower are separated.

[0112] Among them, each adsorption module 110 is separately arranged, which is convenient for individual maintenance of each adsorption module 110 and helps to save maintenance costs. At the same time, different adsorption modules 110 can be reasonably assembled as needed to form the atmosphere conditioning device 100 required for the preservation equipment 200, thereby expanding the scope of use and saving costs.

[0113] Among them, at least part of the adsorption module 110 is integrated in the adsorption tower, and at least part of the adsorption channels in the adsorption tower are separated, so that at least part of the adsorption module 110 can realize modular design, which is beneficial to reduce the overall volume of the gas conditioning device 100. At the same time, it is convenient to install with the fresh-keeping equipment 200, simplifies the installation steps, and is beneficial to improve the installation efficiency. Among them, at least part of the adsorption channels in the adsorption tower are separated, which can make the components of the airflow flowing out through the adsorption channel different, realize the separation of airflows of different components, and improve the accuracy of airflow separation. It can be understood that all adsorption modules 110 can be integrated in the adsorption tower, or part of the adsorption modules 110 can be integrated in the adsorption tower.

[0114] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 100 further includes: a gas storage tank 170 , which corresponds one-to-one to the adsorption module 110 and is connected between the corresponding adsorption module 110 and the first valve assembly 120 .

[0115] Among them, the setting of the gas storage tank 170 allows the gas of the preset components to be stored in the corresponding gas storage tank 170 in advance by using the fluid driving device 130 and the adsorption module 110. When the gas conditioning zone 210 needs to be supplemented with the gas conditioning of the corresponding preset components, the first valve assembly 120 is used to connect the corresponding gas storage tank 170 and the gas inlet 212 of the gas conditioning zone 210, without the need to separate the gas, saving the time of separating the gas of the preset components, which is conducive to improving the gas conditioning efficiency of the gas conditioning zone 210. It can be understood that there can be multiple adsorption modules 110, so that the adsorption modules 110 can be used to store gases of different types of preset components in the corresponding gas storage tanks 170 in advance to meet the needs of supplementing the gas conditioning zone 210 with gases of different preset components.

[0116] At the same time, the provision of the gas storage tank 170 can reduce the pressure drop of the preset component gas separated by the adsorption module 110. When the separated preset component gas is maintained in the gas storage tank 170, it can have a higher pressure, thereby ensuring that the first air pressure is higher than the second air pressure, so that the separated preset component gas can flow smoothly into the gas conditioning zone 210.

[0117] The gas storage tank 170 may be a separate pressure vessel, a micro-pressure container or a solid gas storage medium, or a mixed gas tank. It is understandable that when conditions are suitable, there may be no gas storage tank 170, and the gas from the adsorption module 110 is directly injected into the gas conditioning zone 210 through the first valve assembly 120.

[0118] Specifically, Figure 1 and Figure 2As shown, the adsorption module 110 includes an adsorption module 110A, an adsorption module 110B, and an adsorption module 110C. Correspondingly, the gas storage tank 170 includes a gas storage tank 170A, a gas storage tank 170B, and a gas storage tank 170C to respectively store the gases of preset components separated by the corresponding adsorption modules.

[0119] In some possible embodiments provided by the present disclosure, the gas conditioning device 100 further includes: a pressurizer, which corresponds to the adsorption module 110 one by one, and is used to pressurize the gas flowing from the corresponding adsorption module 110 to the gas conditioning zone 210. The setting of the pressurizer can ensure that the first gas pressure is higher than the second gas pressure, so that the separated gas of the preset components can flow smoothly into the gas conditioning zone 210.

[0120] It is understandable that in some possible embodiments, the pressurizer and the gas storage tank 170 can be provided at the same time to further ensure that the first gas pressure is higher than the second gas pressure.

[0121] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 100 also includes: a filtering and purification device 180, which is connected between the gas storage tank 170 and the corresponding adsorption module 110, and is used to filter at least one of particles, water vapor, and oil in the gas flowing through it.

[0122] The setting of the filter purification device 180 can reduce the condensed water, dust and lubricating grease in the gas path from entering the rear gas storage tank 170, and maintain the cleanliness of the gas storage tank 170 and the rear gas use area. The filter purification device 180 can directly filter through PP cotton, melt-blown cloth or wool felt, or can separate gas and impurities by using a capillary structure, or can filter by separating impurities by physical means such as centrifugation and electric field.

[0123] It is understandable that the filtering and purification device 180 between each adsorption module 110 and the corresponding gas storage tank 170 can be set separately to achieve independent filtration of each component, or a filtering and purification device 180 can be set to filter the gas flowing from each adsorption module 110 to the gas storage tank 170 in a time-sharing multiplexed manner.

[0124] like Figure 1 and Figure 2 The filtering and purification device 180 shown is used for filtering the gas flowing from each adsorption module 110 to the gas storage tank 170 in a time-division multiplexing manner.

[0125] In some possible embodiments provided by the present disclosure, the gas conditioning device 100 further includes a gas delivery device, which is disposed upstream of the gas storage tank 170. In this example, the gas delivery device is disposed between the gas storage tank 170 and the corresponding adsorption module 110.

[0126] The gas delivery device can make the preset component gas separated by the adsorption module 110 flow smoothly into the gas storage tank 170 to maintain the pressure of the gas storage tank 170, and can also make the gas inside the gas storage tank 170 fully emptied for convenient use. The gas delivery device can be a centrifugal turbine pump or an axial turbine pump, or an electric two-stroke air compressor, a diaphragm pump and a piston pump, or a structure that uses the electric field emission effect to achieve pumping.

[0127] like Figure 2 As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 100 also includes: a gas detection device 190, which is used to detect the gas components of the gas conditioning zone 210, and the control device is connected to the gas detection device 190 to adjust the on-off state of the first valve assembly 120 according to the detection result of the gas detection device 190 to adjust the gas components of the gas conditioning zone 210.

[0128] Among them, the gas detection device 190 can detect the gas components in the gas-controlled zone 210, such as the gas detection device 190 can be a sensor for detecting the concentration of each gas-controlled component, or a particle sensor or a mass spectrometer sensor, or other forms of sensors that use gas specific gravity for detection. Therefore, the detection result of the gas detection device 190 can indicate the proportion of the preset gas-controlled components in the gas-controlled zone 210. Therefore, according to the detection result of the gas detection device 190, the channel state of the first valve assembly 120 is adjusted so that the preset component gas separated by the matching adsorption module 110 flows into the gas-controlled zone 210 to adjust the gas components in the gas-controlled zone 210. It can be understood that when the detection result of the gas detection device 190 reaches the preset requirement, it indicates that the gas components in the gas-controlled zone 210 have reached the requirement, and the first valve assembly 120 can be controlled to be closed.

[0129] like Figure 1 and Figure 2 As shown, the second aspect of the present disclosure provides a fresh-keeping device 200, comprising: an atmosphere-controlled area 210, and an atmosphere-controlled device 100 of any one of the first aspects. Since the fresh-keeping device 200 comprises the atmosphere-controlled device 100 of any one of the embodiments of the first aspect, it has all the beneficial technical effects of the atmosphere-controlled device 100, which will not be described one by one here.

[0130] Among them, Figure 2 As shown, the number of the controlled atmosphere zones 210 is at least one, that is, the fresh-keeping device 200 may include one controlled atmosphere zone 210, two controlled atmosphere zones 210, three controlled atmosphere zones 210, or another number of controlled atmosphere zones 210, so as to meet the fresh-keeping requirements of the fresh-keeping device 200 for different types of objects to be preserved and expand the scope of use of the product.

[0131] It is understandable that when the number of the gas-controlled zones 210 is at least two, the gas-controlled device 100 may be in communication with each gas-controlled zone 210 to achieve a gas-controlled effect on the gas in each gas-controlled zone 210 .

[0132] Specifically, Figure 2 As shown, there are three controlled atmosphere zones 210 , including a controlled atmosphere zone 210A, a controlled atmosphere zone 210B, and a controlled atmosphere zone 210C, and the controlled atmosphere device 100 is connected to the three controlled atmosphere zones 210 , respectively.

[0133] In some possible embodiments provided by the present disclosure, the atmosphere-conditioning device 100 and the fresh-keeping equipment 200 are separately arranged, and self-sealing valves are provided at the air inlet 212 and the air outlet 211 of the atmosphere-conditioning zone 210. The first valve assembly 120 of the atmosphere-conditioning device 100 is selectively connected to the air inlet 212 through the self-sealing valve, and the second valve assembly 140 of the atmosphere-conditioning device 100 is selectively connected to the air outlet 211 through the self-sealing valve; wherein the fresh-keeping equipment 200 includes a fresh-keeping box, a fresh-keeping cabinet, and a fresh-keeping bag.

[0134] In this embodiment, the atmosphere-adjusting device 100 and the fresh-keeping device 200 are separately arranged, so that the atmosphere-adjusting device 100 can match different fresh-keeping devices 200 to expand the scope of use. The atmosphere-adjusting device 100 includes a gas storage tank 170, so that the fluid driving device 130 of the atmosphere-adjusting device 100 is connected to the external environment, and the preset component gas can be stored in the corresponding gas storage tank 170 to meet the gas component adjustment requirements of different atmosphere-adjusting zones 210. Of course, the fluid driving device 130 of the atmosphere-adjusting device 100 can also be connected to the atmosphere-adjusting zone 210 to separate the gas flowing out of the atmosphere-adjusting zone and obtain the preset component gas and store it in the gas storage tank 170.

[0135] Among them, the air inlet 212 and the air outlet 211 of the atmosphere control zone 210 of the fresh-keeping device 200 are provided with self-sealing valves, that is, in the absence of external force, the air inlet 212 and the air outlet 211 are closed by the self-sealing valves to ensure the sealing of the atmosphere control zone 210.

[0136] Among them, the first valve assembly 120 of the gas conditioning device 100 is selectively connected to the air inlet 212 through a self-sealing valve, and the second valve assembly 140 of the gas conditioning device 100 is selectively connected to the air outlet 211 through a self-sealing valve, thereby realizing the gas component adjustment of the gas conditioning zone 210.

[0137] Specifically, taking the fresh-keeping device 200 as a fresh-keeping box as an example, after the atmosphere control device 100 is connected to the power supply, the second valve assembly 140 is used to connect the fluid driving device 130 with the external environment, so that the gas in the external environment is separated by the adsorption module 110 and the preset component gas is stored in the corresponding gas storage tank 170. When necessary, the objects to be preserved are placed in a fresh-keeping box, the pipeline of the gas-conditioning device 100 connected with the first valve assembly 120 is connected to the air inlet of the gas-conditioning zone 210, and the self-sealing valve is turned on, the gas detection device 190 on the gas-conditioning device 100 is used to analyze the gas components in the gas-conditioning zone 210, the control device analyzes the detection structure of the gas detection device 190 and determines the required gas components, and then adjusts the on-off state of the first valve assembly 120, and inputs the appropriate preset component gas into the gas-conditioning zone 210, when the detection result of the gas detection device 190 meets the preset requirements, such as when the detection result of the detection device matches the type of the object to be preserved, the control device controls the first valve assembly 120 to close, and then pulls out the connecting pipe connected with the first valve assembly 120 from the air inlet 212, and the self-sealing valve closes the air inlet, that is, the adjustment of the gas components in the fresh-keeping box is completed. Then the fresh-keeping box can be placed in a suitable place for storage. It can be understood that this embodiment is also applicable to dense fresh-keeping bags, hot-melt sealed packaging bags, self-sealing packaging bags, etc.

[0138] It is understandable that the pipeline connected to the second valve assembly 140 can also be inserted into the air outlet to connect the self-sealing valve, and the state of the second valve assembly 140 can be adjusted to connect the air outlet and the fluid driving device 130, and the state of the third valve assembly 160 can be adjusted to connect the fluid driving device 130 and the exhaust device 150. In this way, the gas in the atmosphere-controlled zone 210 can be sucked by the fluid driving device 130 and then discharged by the exhaust device 150, so that the atmosphere-controlled zone 210 is in a vacuum negative pressure state, thereby achieving the preservation of the objects to be preserved.

[0139] It is understandable that, in some examples, the air inlet 212 and the air outlet 211 of the fresh-keeping device 200 may also be integrated into one vent hole, and a self-sealing valve may be provided at the vent hole, and the above-mentioned effect can still be achieved.

[0140] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the fresh-keeping device 200 is a refrigerator, which includes: a box body 220, and a door body 230 for opening and closing the box body 220. The box body 220 is provided with an atmosphere-controlled area 210, and the atmosphere-controlled device 100 is provided on the box body 220 and / or the door body 230. In some embodiments, the atmosphere-controlled device 100 is located outside the refrigerator.

[0141] That is to say, the gas conditioning device 100 can be arranged on the box body 220, or on the door body 230, or can be located outside the box body 220, thereby expanding the installation range of the gas device.

[0142] The gas conditioning device 100 is located outside the box 220, which facilitates the communication between the fluid driving device 130 and the external environment, and also facilitates the communication between the exhaust device 150 and the external environment.

[0143] like Figure 2 As shown, in the above embodiment, the distance between the atmosphere-conditioning device 100 and the top wall of the box 220 is 18 cm to 25 cm; the distance between the atmosphere-conditioning device 100 and the side wall of the box 220 is 18 cm to 25 cm; the distance between the atmosphere-conditioning device 100 and the rear wall of the box 220 is 18 cm to 25 cm.

[0144] Among them, by reasonably setting the distance between the air conditioning device 100 and the top wall of the box 220, the side wall of the box 220, and the rear wall of the box 220, it can ensure that the air conditioning device 100 is reliably connected to the air inlet 212 and the air outlet 211 of the air conditioning zone 210, and at the same time, it can minimize the impact of the air conditioning device 100 on the external dimensions and installation dimensions of the refrigerator. Specifically, the distance between the air conditioning device 100 and the top wall of the box 220 can be 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the air conditioning device 100 and the side wall of the box 220 is 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the air conditioning device 100 and the rear wall of the box 220 is 18cm, 20cm, 22cm, 25cm, or other sizes. It should be noted that, in this embodiment, the top wall of the box body 220 refers to the outer top surface of the box body 220, the side wall of the box body 220 refers to the outer wall surface of one side of the box body 220 on which the air conditioning device 100 is installed, and the rear wall of the box body 220 refers to the outer wall surface of the box body 220 opposite to the door body 230.

[0145] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by the present disclosure, the fresh-keeping device 200 also includes: an evaporator 270, a compressor 240, a condenser 250, and a throttling element 260, which are connected in sequence through a refrigerant pipeline to form a circulation path, wherein the first valve assembly 120 is arranged close to the condenser 250, and the fluid driving device 130 is arranged in a spherical space with the compressor as the center and a preset size as the radius.

[0146] Among them, the circulation passage formed by the refrigerant pipeline cools the air flow in the area through the condenser 250 to reduce the temperature of the air-conditioning zone 210 or transmits dry cold air flow to the air-conditioning zone 210 through a suitable air duct to keep the temperature of the air-conditioning zone 210 low. Thus, the low-temperature gas is used to extend the preservation time of the objects to be preserved in the air-conditioning zone 210.

[0147] The first valve assembly 120 is disposed close to the condenser 250 , so that the air input into the air conditioning zone 210 by the air conditioning device 100 can be kept at a low temperature.

[0148] Among them, the fluid driving device 130 is arranged in a spherical space with the compressor as the center and a preset size as the radius. In this way, it can be ensured that there is sufficient space between the fluid driving device 130 and the compressor to arrange the pipes connecting the fluid driving device 130 and the compressor. At the same time, space is provided for the maintenance of the fluid driving device 130 and the compressor, which is convenient for user operation.

[0149] In the above embodiment, the door body 230 is located on the side of the box body 220, that is, the refrigerator is a side-opening refrigerator. When the door body 230 is a single-opening door body 230, the preset size is 650mm to 750mm. Specifically, the preset size can be 650mm, 700mm, 750mm, or other sizes that meet the requirements.

[0150] Among them, when the door body 230 is located on the side of the box body 220, that is, the refrigerator is a side-opening refrigerator, when the door body 230 is a double-door body 230, the preset size is 1150mm to 1250mm. Specifically, the preset size can be 1150mm, 1200mm, 1250mm, or other sizes that meet the requirements.

[0151] Among them, the door body 230 is located at the top of the box body 220. If the refrigerator is a freezer, the door body 230 is an upward-opening door body 230, and the preset size is 2400mm to 2600mm. Specifically, the preset size can be 2400mm, 2500mm, 2600mm, or other sizes that meet the requirements.

[0152] The third aspect of the present disclosure is as follows Figure 4 As shown, a control method of a fresh-keeping device 200 is provided. The control method is used for the fresh-keeping device 200 of any embodiment in the second aspect. The control method includes:

[0153] Determine target information of gas composition in the controlled atmosphere zone;

[0154] Adjust the on / off states of the first valve assembly, the second valve assembly, and the third valve assembly so that the gas flowing through the target adsorption module is input into the gas conditioning zone to adjust the gas components in the gas conditioning zone, wherein the target adsorption module is the adsorption module in the adsorption module that matches the target information.

[0155] The target information of the gas components of the controlled atmosphere zone 210 is related to the types of objects to be preserved stored in the controlled atmosphere zone 210 , and the target information of the gas components of the controlled atmosphere zone 210 can be determined by the types of objects to be preserved stored in the controlled atmosphere zone 210 .

[0156] Specifically, the preservation device 200 can intelligently obtain the type of objects to be preserved stored in the gas conditioning zone 210, such as determining the type of objects to be preserved stored in the gas conditioning zone 210 through an infrared device, a camera device or other detection device, and of course the type of objects to be preserved can also be manually input by the user; then, the control device of the preservation device can determine the target information of the gas components of the gas conditioning zone 210 according to the type of objects to be preserved stored in the gas conditioning zone 210, such as the control device determines the target information of the gas components of the gas conditioning zone 210 according to the type of objects to be preserved stored in the gas conditioning zone 210 through a certain algorithm or a server. Specifically, the target information can be the proportion of each gas component, such as nitrogen proportion A, oxygen proportion B, carbon dioxide proportion C, etc.

[0157] Among them, the target adsorption module 110 is an adsorption module 110 in the adsorption module 110 that matches the target information. If the target information includes the nitrogen percentage, the target adsorption module 110 includes an adsorption module 110 that can separate nitrogen from the gas flowing through it. If the target information includes the nitrogen percentage and the oxygen percentage, the target adsorption module 110 can include an adsorption module 110 that can separate nitrogen from the gas flowing through it, and an adsorption module 110 that can separate oxygen from the gas flowing through it, and so on, which are not listed one by one in the present disclosure.

[0158] Therefore, according to the target information, the on and off states of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160 are adjusted, and the first air pressure is controlled to be higher than the second air pressure, so that the gas flowing through the target adsorption module 110 is input into the air conditioning zone 210, and the gas in the air conditioning zone 210 is discharged from the air conditioning zone 210, and then the gas components of the air conditioning zone 210 can be adjusted so that the air conditioning components of the air conditioning zone 210 meet the target information, so as to extend the preservation time of the objects to be preserved in the air conditioning zone 210 and improve the preservation quality of the objects to be preserved.

[0159] Among them, the first air pressure is higher than the second air pressure, which can ensure that the gas pressure flowing out of the adsorption module 110 is higher than the gas pressure of the gas conditioning zone 210, thereby ensuring that the airflow of the preset components separated by the adsorption module 110 can flow smoothly and reliably into the gas conditioning zone 210 to adjust the gas components of the gas conditioning zone 210.

[0160] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0161] Obtain current information on gas composition in the controlled atmosphere area;

[0162] Determining that the current information does not match the target information, and executing the step of adjusting the on / off states of the first valve assembly, the second valve assembly, and the third valve assembly so that the gas flowing through the target adsorption module is input into the gas conditioning zone;

[0163] Until the current information matches the target information, at least one of the first valve component, the second valve component, and the third valve component is closed.

[0164] Among them, the current information of the gas components in the gas-controlled zone 210 can indicate the current concentration and ratio of the gas components in the gas-controlled zone 210, and then by matching the current information of the gas components in the gas-controlled zone 210 with the target information, it can be determined whether the current gas components in the gas-controlled zone 210 have reached the target information. When it is determined that the current information does not match the target information, it means that the current gas components in the gas-controlled zone 210 have not reached the target information, so the step of adjusting the on-off state of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160 is performed to input the gas flowing through the target adsorption module into the gas-controlled zone, so that the gas flowing through the target adsorption module 110 is input into the gas-controlled zone 210, and the gas in the gas-controlled zone 210 is discharged from the gas-controlled zone 210, and then the gas components in the gas-controlled zone 210 can be adjusted so that the gas-controlled components in the gas-controlled zone 210 meet the target information, so as to extend the preservation time of the objects to be preserved in the gas-controlled zone 210 and improve the preservation quality of the objects to be preserved.

[0165] Until the current information matches the target information, it indicates that the current gas composition of the gas-controlled zone 210 reaches the target information, and then at least one of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160 is controlled to be closed, so that the gas in the gas-controlled zone 210 and the gas-controlled device 100 stop circulating, to ensure that the gas composition in the gas-controlled zone 210 is under the target information, and at the same time, save the energy consumption of the gas device.

[0166] Among them, the gas components of the gas-controlled atmosphere zone 210 can be detected by the gas detection device 190. For example, the gas detection device 190 can be a sensor for detecting the concentration of the corresponding gas-controlled atmosphere component, or a particle sensor or a mass spectrometer sensor, or other forms of sensors that use gas specific gravity for detection.

[0167] Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the step of adjusting the on-off state of the first valve assembly, the second valve assembly, and the third valve assembly so that the gas flowing through the target adsorption module is input into the gas conditioning zone specifically includes:

[0168] The second valve assembly is controlled to connect the gas outlet of the gas conditioning zone with the fluid driving device, the third valve assembly connects the fluid driving device with the target adsorption module, and the first valve assembly connects the target adsorption module with the gas inlet of the gas conditioning zone.

[0169] In this embodiment, by adjusting the on / off states of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160, the gas outlet 211 of the gas-controlled zone 210 is connected to the fluid driving device 130, the fluid driving device 130 is connected to the target adsorption module 110, the target adsorption module 110 is connected to the exhaust device 150, and the target adsorption module 110 is connected to the gas inlet 212 of the gas-controlled zone 210. Thus, the gas in the gas-controlled zone 210 is separated by the target adsorption module 110 through the fluid driving device 130 and then returned to the gas-controlled zone 210, so as to adjust the gas components in the gas-controlled zone 210. In some embodiments, the remaining gas after separation by the adsorption module 110 is discharged through the exhaust device 150. Among them, the first gas pressure is higher than the second gas pressure, ensuring that the preset component gas flow after separation by the adsorption module 110 can smoothly enter the gas-controlled zone 210.

[0170] Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the step of adjusting the on-off state of the first valve assembly, the second valve assembly, and the third valve assembly so that the gas flowing through the target adsorption module is input into the gas conditioning zone specifically includes:

[0171] Control the second valve assembly 140 to connect the air outlet of the gas-controlled zone 210 with the exhaust device 150, and connect the fluid-driving device 130 with the external environment; control the third valve assembly 160 to connect the fluid-driving device 130 with the target adsorption module 110, and connect the first valve assembly 120 with the target adsorption module 110 and the air inlet of the gas-controlled zone 210.

[0172] In this embodiment, by adjusting the states of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160, the gas outlet 211 of the gas-controlled zone 210 is connected to the exhaust device 150, the fluid driving device 130 is connected to the external environment, the target adsorption module 110 is connected to the exhaust device 150, and the target adsorption module 110 is connected to the gas inlet 212 of the gas-controlled zone 210. As a result, the gas in the gas-controlled zone 210 is discharged through the exhaust device 150, and the gas in the external environment is separated by the target adsorption module 110 after passing through the fluid driving device 130 and then returned to the gas-controlled zone 210, so as to adjust the gas components in the gas-controlled zone 210. In some embodiments, the remaining gas after separation by the adsorption module 110 is discharged through the exhaust device 150. Among them, the first air pressure is higher than the second air pressure, ensuring that the preset component airflow after separation by the adsorption module 110 can smoothly enter the gas-controlled zone 210.

[0173] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0174] Before executing the step of adjusting the on-off state of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160, the method also includes: determining the injection duration of each target adsorption module 110 according to the target information; after executing the step of adjusting the on-off state of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160, the control method also includes: controlling the first valve assembly 120 to connect each target adsorption module 110 with the air inlet for a duration equal to or substantially equal to the injection duration of the corresponding target adsorption module 110; based on the connection duration of all target adsorption modules 110 reaching the injection duration, closing the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160.

[0175] In this embodiment, the gas injection duration of each target adsorption module 110 is determined according to the target information. Specifically, the gas component proportion of the conventional atmosphere, the target information of the gas component of the gas-controlled zone 210, the loss of each component gas during the discharge of the conventional gas through the gas outlet 211 of the gas-controlled zone 210, and the increment of each component gas flowing into the gas-controlled zone 210 through the gas inlet 212 of the gas-controlled zone 210 can be combined with the above-mentioned various factors to determine the gas injection duration of the fluid separated by each target adsorption module 110 injected into the gas-controlled zone 210 when the gas component of the gas-controlled zone 210 reaches the target information from the current information. Then, the on-off state of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160 are adjusted to inject the fluid separated by the target adsorption module 110 into the gas-controlled zone 210, and adjust the gas component of the gas-controlled zone 210.

[0176] Among them, the first valve assembly 120 is controlled to connect each target adsorption module 110 with the gas inlet 212 for a duration equal to or substantially equal to the gas injection duration of the corresponding target adsorption module 110, thereby ensuring that the duration of the gas of the preset components separated by each adsorption module 110 entering the gas-controlled zone 210 is equal to the corresponding gas injection duration, so that the preset components of the gas-controlled zone 210 reach the corresponding target information. When the connection duration of all target adsorption modules 110 reaches the gas injection duration of the corresponding target adsorption module 110, it means that the gas components corresponding to all target adsorption modules 110 in the gas-controlled zone 210 have reached the requirements, that is, the gas components in the gas-controlled zone 210 have reached the target information. At this time, the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160 are closed, so that the gas in the gas-controlled zone 210 and the gas-controlled device 100 stop circulating, so as to ensure that the gas components in the gas-controlled zone 210 are under the target information, and at the same time, save the energy consumption of the gas device.

[0177] Further, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the step of adjusting the on-off state of the first valve assembly, the second valve assembly, and the third valve assembly so that the gas flowing through the target adsorption module is input into the gas conditioning zone specifically includes:

[0178] The second valve assembly 120 is controlled to connect the gas-controlled zone 210 with the exhaust device 150 of the gas-controlled device 100, and the fluid driving device 130 is connected with the external environment. The third valve assembly 160 is controlled to connect the fluid driving device 130 with the target adsorption module 110, and the target adsorption module 110 with the exhaust device 150. The first valve assembly 120 connects the target adsorption module 110 with the gas-controlled zone 210. The first air pressure is higher than the second air pressure, so that the gas in the gas-controlled zone 210 is discharged through the exhaust device 150, and the gas in the external environment flows through the fluid driving device 130, flows through the target adsorption module 110, and then flows into the gas-controlled zone 210, and the remaining gas is discharged through the exhaust device 150.

[0179] In this embodiment, by adjusting the states of the first valve assembly 120, the second valve assembly 140, and the third valve assembly 160, the gas conditioning zone 210 is connected to the exhaust device 150, the fluid driving device 130 is connected to the external environment, the fluid driving device 130 is connected to the target adsorption module 110, the target adsorption module 110 is connected to the exhaust device 150, and the target adsorption module 110 is connected to the air inlet 212 of the gas conditioning zone 210. Thus, the gas in the gas conditioning zone 210 is discharged through the exhaust device 150, the gas in the external environment is separated by the target adsorption module 110 after passing through the fluid driving device 130 and then returned to the gas conditioning zone 210, so as to adjust the gas components in the gas conditioning zone 210, and the remaining gas after separation by the adsorption module 110 is discharged through the exhaust device 150. Among them, the first air pressure is higher than the second air pressure, ensuring that the preset component airflow after separation by the adsorption module 110 can smoothly enter the gas conditioning zone 210.
