The fluid handling device 100 includes: a first valve assembly 110, a second valve assembly 150, a fluid driving device 140, a suction and desorption device 120, an air conditioning device 130 and a control device; the fluid driving device One end of 140 is connected to the suction and removal device 120 and the air conditioning device 130 respectively through the first valve assembly 110, the other end of the fluid driving device 140 is connected to the air supply channel 242 through the second valve assembly 150, the suction and removal device 120 is connected to the storage compartment 210 through the return air channel 241, the suction and removal device 120 is used to remove preset components in the air flow passing through it, the air conditioning device 130 is connected to the air conditioning zone 214 through the return air channel 241, and the air conditioning device 130 is used to separate preset components in the air flow passing through it.

[0119] The control device is used to control the on-off state of the suction and desorption device 120 and the storage room 210, and / or the on-off state of the gas-adjusting device 130 and the gas-adjusting zone 214. The control device is connected to the first valve assembly 110 and the second valve assembly 150 to adjust the on-off state of the suction and desorption device 120 and the storage room, and / or the on-off state of the gas-adjusting device 130 and the gas-adjusting zone 214.

[0120] It should be noted that if Figure 3 As shown, the air outlet of the storage room 210 and the air conditioning outlet of the air conditioning zone 214 are both connected to the air supply channel 242, and air supply valves are respectively provided on the connecting pipelines of the air outlet of the storage room 210, the air conditioning outlet of the air conditioning zone 214 and the air supply channel 242, and each air supply valve is connected to the control device, and the on-off state of the storage room 210 and the air supply channel 242, and the on-off state of the air conditioning zone 214 and the air supply channel 242 can be controlled by the corresponding air supply valve.

[0121] like Figure 3As shown, the air inlet of the storage room 210 and the air conditioning inlet of the air conditioning zone 214 are both connected to the return air channel 241, and return air valves are respectively provided on the connecting pipelines of the air inlet of the storage room 210, the air conditioning inlet of the air conditioning zone 214 and the return air channel 241, and each return air valve is connected to the control device, and the on-off state of the storage room 210 and the return air channel 241, and the on-off state of the air conditioning zone 214 and the return air channel 241 can be controlled by the corresponding return air valve.

[0122] Among them, Figures 4 to 6 As shown, the fresh-keeping device 200 includes a storage compartment 210 for accommodating objects to be preserved, and the storage compartment 210 includes a freezing compartment 211, a refrigerating compartment 212, and may also include a variable temperature compartment 213. The fresh-keeping device 200 also includes a refrigeration module, and an air supply sub-channel 2421 is connected between the freezing compartment 211 and the refrigerating compartment 212 of the storage compartment 210. The air supply sub-channel 2421 is used to introduce the dry cold airflow passing through the refrigeration module into the storage compartment 210. The airflow in the storage compartment 210 enters the first adsorption module 121 through the air supply channel 242 (not shown in the figure) and the first adsorption channel 123. The airflow after passing through the first adsorption module 121 enters the return air channel 241. The return air channel 241 is used to guide the airflow flowing out of the storage compartment 210 to flow through the refrigeration module. As a result, the airflow in the storage compartment 210 and the airflow flowing through the refrigeration module form a circulating airflow passage under the guidance of the air supply channel 242 and the return air channel 241, so that the airflow in the storage compartment 210 can be kept in a low temperature state for a long time, so as to utilize the low temperature to reduce the activity of microorganisms and enzymes, slow down the respiration of food and microorganisms, and extend the shelf life.

[0123] Among them, the adsorption and desorption device 120 is used to remove preset molecules in the air flow flowing through it. The preset molecules can be odor molecules and / or moisture molecules. When the gas flows through the adsorption and desorption device 120, the odor molecules and / or moisture molecules in the gas can be adsorbed, and the gas after adsorption has no odor and / or is relatively dry.

[0124] Among them, Figure 3 As shown, the storage room 210 is also provided with a controlled atmosphere area 214. The number of controlled atmosphere areas 214 in each storage room 210 may be one, two or more. The controlled atmosphere areas 214 may be understood as mutually independent and isolated areas in the storage room 210 for accommodating different objects to be preserved. Alternatively, the controlled atmosphere areas 214 may also be independent storage rooms 210. The controlled atmosphere areas 214 are provided with a controlled atmosphere inlet and a controlled atmosphere outlet to realize the circulation of the airflow in the controlled atmosphere area 214 and the external airflow. Figure 3 and Figure 7 As shown, the controlled atmosphere zone 214 may include a controlled atmosphere zone 214A, a controlled atmosphere zone 214B, and a controlled atmosphere zone 214C.

[0125] Among them, the gas conditioning device 130 is used to separate preset components in the gas flow flowing through it. It can be understood that the preset components can be at least one of oxygen, nitrogen, carbon dioxide, etc. Taking the preset component as nitrogen as an example, when the gas flows through the gas conditioning device 130, the nitrogen in the gas can be separated. When the preset components are nitrogen and carbon dioxide, when the gas flows through the gas conditioning device 130, the nitrogen and carbon dioxide in the gas can be separated.

[0126] In this embodiment, the fluid driving device 140 of the fluid handling device 100 is selectively connected to the suction and desorption device 120 and the gas conditioning device 130 respectively through the first valve assembly 110, the suction and desorption device 120 includes a first adsorption channel 123, a first adsorption module 121, a desorption module 122, and a desorption channel 124, and the gas conditioning device 130 includes at least one second adsorption module 131. The other end of the fluid driving device 140 is connected to the air outlet of the air supply channel 242 through the second valve assembly 150, and the suction and desorption device 120 is also connected to the air inlet of the storage room 210, and the gas conditioning device 130 is also connected to the gas conditioning inlet of the gas conditioning zone 214. Therefore, by reasonably adjusting the states of the first valve assembly 110 and the second valve assembly 150 through the control device, the storage room 210 can be selectively connected to the suction and desorption device 120 through the air supply channel 242, and combined with the return air channel 241 to form an air circulation passage. That is, the airflow flowing out of the storage compartment 210 passes through the suction and desorption device 120 and then flows through the refrigeration module, and is sent back to the storage compartment 210 by the air duct. Therefore, in the process of the odor generated by the oxidation and decomposition of the objects to be preserved in the storage compartment 210 flowing through the suction and desorption device 120, the suction and desorption device 120 can remove the preset molecules in the airflow flowing through the suction and desorption device 120, wherein the preset molecules can be odor molecules, that is, the suction and desorption device 120 has the function of removing odor. In addition, the airflow flowing through the refrigeration module through the return air channel 241 is relatively fresh and odor-free, reducing the odor level of the dry cold airflow that flows into the storage compartment 210 again during the circulation of the airflow, making the airflow in the storage compartment 210 relatively fresh and odor-free, reducing the impact of the odor on the objects to be preserved, and improving the user experience. It can be understood that the preset molecules are moisture molecules, which can also achieve the above technical effects, and will not be repeated here.

[0127] Among them, by reasonably adjusting the states of the first valve assembly 110 and the second valve assembly 150 through the control device, the atmosphere-controlled zone 214 and the atmosphere-controlled device 130 can selectively form an airflow circulation passage, and the gas in the atmosphere-controlled zone 214 can be separated into airflows of preset components by the atmosphere-controlled device 130 and then returned to the atmosphere-controlled zone 214. Therefore, the gas components in the atmosphere-controlled zone 214 can be adjusted, so that the adjusted gas components in the atmosphere-controlled zone 214 are conducive to extending the preservation time of the objects to be preserved and improving the preservation quality of the objects to be preserved.

[0128] That is to say, the fluid processing device 100 provided by the present disclosure can selectively connect the storage room 210 with the adsorption and desorption device 120 to adsorb the preset molecules in the airflow in the storage room 210, and / or connect the air conditioning zone 214 with the air conditioning device 130 to adjust the gas components in the air conditioning zone 214, according to the processing requirements of the preset molecules in the airflow in the storage room 210 and the requirements of the gas components in the gas conditioning zone 214. In this way, the requirements of the storage room 210 and the gas conditioning zone 214 for the internal airflow can be met, the functional diversification of the fluid processing device 100 is achieved, the use scope of the fluid processing device 100 is expanded, and it is conducive to improving user satisfaction.

[0129] Among them, the fluid treatment device 100 provided by the present disclosure can control the adsorption and desorption device 120 to be connected to the storage room 210 through the control device in one example, and at the same time, control the gas conditioning device 130 to be separated from the gas conditioning zone 214, so as to only realize the function of adsorbing preset molecules on the airflow in the storage room 210; in another example, the adsorption and desorption device 120 can be controlled to be separated from the storage room 210, and at the same time, control the gas conditioning device 130 to be connected to the gas conditioning zone 214, so as to only realize the function of adjusting the gas components in the gas conditioning; in another example, the adsorption and desorption device 120 can be controlled to be connected to the storage room 210, and at the same time, control the gas conditioning device 130 to be connected to the gas conditioning zone 214, so as to simultaneously realize the function of adsorbing preset molecules on the airflow in the storage room 210 and the function of adjusting the gas components in the gas conditioning. Therefore, the function of the fluid treatment device 100 can be reasonably selected according to different needs, realizing the diversification of the functions of the fluid treatment device 100, expanding the scope of use, and improving the user's satisfaction.

[0130] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some possible embodiments provided by the present disclosure, the adsorption and desorption device 120 includes a first adsorption channel 123, a first adsorption module 121, a desorption module 122, and a desorption channel 124. The two ends of the first adsorption channel 123 are respectively connected to the first valve assembly 110 and the first adsorption module 121, and the first adsorption module 121 is respectively connected to the first adsorption channel 123 and the desorption channel 124. The first adsorption module 121 is used to remove preset molecules in the airflow flowing through it, and the desorption module 122 is used to make the airflow in the desorption channel 124 be under preset conditions to desorb the preset molecules in the first adsorption module 121.

[0131] The airflow flowing out of the storage compartment 210 of the fresh-keeping device 200 enters the first adsorption module 121 after passing through the first adsorption channel 123, and then flows through the return air channel 241 and the refrigeration module, and is sent back to the storage compartment 210. Therefore, the odor generated by the oxidation and decomposition of the objects to be preserved in the storage compartment 210 can be removed by the first adsorption module 121 in the process of passing through the first adsorption module. For example, the preset molecules can be odor molecules, that is, the first adsorption module 121 has the function of removing odor, so that the airflow flowing through the refrigeration module through the return air channel 241 is relatively fresh and odor-free, reducing the influence of the odor on the objects to be preserved and improving the user experience.

[0132] The first adsorption module 121 is connected to the desorption channel 124 and the first adsorption channel 123. The desorption channel 124 can be Figures 4 to 6 As shown by the dotted lines in the figure, the desorption module 122 is used to make the airflow in the desorption channel 124 under preset conditions to desorb the preset molecules in the first adsorption module. Thus, the desorption module 122 can be used to desorb the preset molecules in the first adsorption module 121 connected to the desorption channel 124, thereby improving or restoring the adsorption capacity of the first adsorption module 121. Thus, the adsorption time of the first adsorption module 121 is extended, the adsorption capacity of the first adsorption module 121 is improved, and the problem of the first adsorption module 121 losing its adsorption capacity after adsorption saturation and affecting the deodorization effect, or the need to replace the first adsorption module 121 with a new one, which is expensive, is avoided. That is, the desorption device 120 has the desorption regeneration ability under the action of the desorption module 122, thereby ensuring a good deodorization effect and saving the use cost.

[0133] Among them, the preset condition may be a desorption temperature and / or a desorption pressure, that is, the desorption module 122 may make the airflow in the first desorption channel 124 at the desorption temperature of the first adsorption module 121, so that the preset molecules in the first adsorption module 121 are desorbed, and at this time, the desorption module 122 may be a structure with heating capability. And / or, the desorption module 122 may make the airflow in the desorption channel 124 at the desorption pressure of the first adsorption module 121, so that the preset molecules in the first adsorption module 121 are desorbed, and at this time, the desorption module 122 may be a pressure regulating structure.

[0134] In some possible embodiments provided by the present disclosure, the adsorption / desorption device 120 also includes a first valve body 126A and a second valve body 126B. The first valve body 126A is arranged on the passage between the first adsorption module 121 and the first adsorption channel 123, and the second valve body 126B is arranged on the passage between the first adsorption module 121 and the return air channel 241. The first valve body 126A and the second valve body 126B are used to adjust the on-off of the passages in which they are located.

[0135] Among them, the control device is connected to the first valve body 126A and the second valve body 126B respectively, and the control device is used to control the first valve body 126A and the second valve body 126B to cut off the passage where they are at least when controlling the desorption module 122 to work, or control the first valve body 126A to cut off the passage where it is; when controlling the first adsorption module 121 to work, control the first valve body 126A and the second valve body 126B to connect the passage where they are.

[0136] Among them, since the first valve body 126A and the second valve body 126B can adjust the on-off of the passages in which they are located, the first valve body 126A can be used to connect or disconnect the passage between the first adsorption channel 123 and the first adsorption module 121, and the second valve body 126B can be used to connect or disconnect the passage between the first adsorption module 121 and the return air channel 241, that is, the first valve body 126A and the second valve body 126B can be used to connect or disconnect the storage room 210 and the adsorption and desorption device 120. With such a configuration, the desorption module 122 processes the airflow in the desorption channel 124 so that the airflow in the desorption channel 124 reaches the preset condition to perform desorption processing on the first adsorption module 121. The first valve body 126A and the second valve body 126B can be used to isolate the first adsorption module 121 and the first adsorption channel 123 from the return air channel 241, thereby preventing the airflow in the adsorption and desorption device 120 from flowing into the storage compartment 210, thereby preventing the desorption module 122 from working and causing the airflow in the first adsorption channel 123 to increase in temperature and flow into the storage compartment 210, thereby affecting the cooling effect of the storage compartment 210. Therefore, even when the desorption module 122 is working, it is possible to ensure that the storage compartment 210 has a good cooling effect. That is, the setting of the first valve body 126A and the second valve body 126B can isolate the hot air flow in the adsorption / desorption device 120 from the cold air flow in the storage compartment 210, so as to reduce the workload of the refrigerator compressor 280 and reduce the overall energy consumption of the refrigerator, thereby realizing the function of simultaneously starting the desorption module 122 of the adsorption / desorption device 120 and the refrigeration module of the preservation device 200.

[0137] Specifically, the refrigeration module and the desorption module 122 of the fresh-keeping device 200 can be controlled to work simultaneously for at least one working period, and the desorption module 122 is used to make the airflow in the desorption channel 124 reach the preset conditions to desorb the preset molecules in the first adsorption module 121, and at the same time, the refrigeration module is used to refrigerate the storage compartment 210. Compared with the refrigeration module and the desorption module 122 that cannot work at the same time and need to work at intervals, such a setting avoids the need for the refrigeration module to stop working when the desorption module 122 is working to affect the refrigeration effect of the storage compartment 210. In other words, in the fluid treatment device 100 of the embodiment of the present disclosure, even when the desorption module 122 is desorbing the preset molecules in the first adsorption module 121, the refrigeration module can continue to work to ensure a good refrigeration effect of the storage compartment 210.

[0138] Among them, the first valve body 126A and the second valve body 126B are both provided with heat insulation, and the heat insulation can be a vacuum insulation, an air insulation, a foam filling, etc., to reduce radiation heat transfer. The first valve body 126A is movably connected to the cavity wall of the shell or the first adsorption channel 123 to open and close the adsorption inlet; the second valve body 126B is movably connected to the cavity wall of the return air channel 241 to open and close the adsorption outlet. Specifically, the first valve body 126A can be connected to the cavity wall of the first adsorption channel 123 through a hinge or a sliding mechanism to open or close the adsorption inlet; the second valve body 126B can be connected to the cavity wall of the return air channel 241 through a hinge or a sliding mechanism to open or close the adsorption outlet.

[0139] As an application form, Figure 2 The first valve body 126A is connected to the cavity wall of the first adsorption channel 123 with a hinge structure, and the second valve body 126B is connected to the cavity wall of the return air channel 241 with a hinge structure. The first valve body 126A and the second valve body 126B can open and close the adsorption inlet and adsorption outlet respectively. When the adsorption and desorption device 120 is in the adsorption state, the first valve body 126A and the second valve body 126B open the adsorption inlet and adsorption outlet, and the airflow in the storage room 210 enters the adsorption and desorption device 120, and returns to the storage room 210 after adsorbing the preset molecules by the first adsorption module 121; when the adsorption and desorption device 120 is in the desorption state, the first valve body 126A and the second valve body 126B close the adsorption inlet and adsorption outlet, and the airflow in the storage room 210 is isolated from the first adsorption module 121. The desorption module 122 works to heat the gas in the desorption channel 124, so that the preset molecules on the first adsorption module 121 are desorbed and discharged to the external environment or decomposed with the airflow in the desorption channel 124. At this time, since the suction and desorption device 120 is in an isolated state from the storage room 210, the heated air in the suction and desorption device 120 will not affect the low temperature state of the storage room 210. The temperature control logic of the fresh-keeping device 200 can still control the compressor 280 of the refrigeration module to start and stop to achieve refrigeration.

[0140] like Figure 3 As shown, in some possible embodiments provided by the present disclosure, the fluid treatment device 100 also includes: a turbine 160 and a radiator 170, the turbine 160 is connected to the passage between the first adsorption module 121 and the return air channel 241, the turbine 160 is dynamically connected to the fluid drive device 140, the radiator 170 is located between the fluid drive device 140 and the first adsorption module 121, in this embodiment, the radiator 170 is located between the fluid drive device 140 and the first valve assembly 110, and the desorption module 122, the first adsorption module 121, the turbine 160, the fluid drive device 140 and the radiator 170 constitute a thermodynamic cycle system.

[0141] It should be noted that, in some embodiments, when the first valve assembly 110 is provided, the first valve body 126A may be removed. The opening and closing of the second valve body 126B may be controlled according to requirements.

[0142] The fluid driving device 140 may be an air compressor, the turbine 160 may be connected to the fluid driving device 140 through a shaft, and the fluid driving device 140 is driven by its own motor and the turbine 160 .

[0143] In some embodiments, when the first adsorption module 121 of the suction and desorption device 120 is working, the second valve assembly 150 connects the fluid driving device 140 and the storage room 210, and the first valve assembly 110 controls the connection between the fluid driving device 140 and the suction and desorption device 120. When the second valve body 126B and the return air valve control the connection between the suction and desorption device 120 and the storage room 210, the gas in the storage room 210 is compressed by the fluid driving device 140, flows into the first adsorption module 121 from the first valve assembly 110 through the radiator 170, and the gas adsorbed by the first adsorption module 121 is sent back to the storage room 210 after being decelerated and reduced in pressure by the turbine.

[0144] In another embodiment, when the desorption module 122 of the adsorption and desorption device 120 is working, the second valve assembly 150 isolates the fluid driving device 140 from the storage compartment 210, the first valve assembly 110 controls the fluid driving device 140 and the adsorption and desorption device 120 to be isolated, and the second valve body 126B and the return air valve control the adsorption and desorption device 120 and the storage compartment 210 to be isolated. The desorption module 122 heats the airflow in the desorption channel 124, and at the same time, the first adsorption module 121 is heated. In this case, the airflow flowing through the first adsorption module 121 is heated, and the heated airflow is expanded and cooled to a lower temperature through the turbine 160 and transported to the storage compartment 210. The excess energy is converted into kinetic energy by the turbine 160 and transmitted to the fluid driving device 140 through the shaft, driving the piston of the fluid driving device 140 to compress the air, and the energy is converted into the internal energy of the air, and finally the energy is dissipated into the atmosphere when the gas passes through the radiator 170. For the entire fresh-keeping device 200 system, the desorption module 122, the first adsorption module 121, the turbine 160, the fluid drive device 140, and the radiator 170 are an independent thermodynamic cycle process, with the hot end being the desorption module 122 and the cold end being the radiator 170. Energy is converted from the heat energy in the first adsorption module 121 into the motor input kinetic energy of the fluid drive device 140, and is eventually dissipated by the radiator 170 in the form of convection or radiation. The entire thermodynamic cycle process will not pass through the storage compartment 210, so that the refrigeration module of the fresh-keeping device 200 can work normally as needed, without the need to control the compressor 280 to stop when the desorption module 122 is working, so as to avoid the temperature fluctuation in the storage compartment 210 causing the change in the fresh-keeping conditions and causing food to spoil.

[0145] like Figures 4 to 6 As shown, in some possible embodiments provided by the present disclosure, the first adsorption channel 123 and the desorption channel 124 are isolated from each other, and / or the desorption module 122 is separately arranged from the first adsorption module 121, and / or the desorption module 122 is arranged away from the first adsorption channel 123.

[0146] The first adsorption channel 123 and the desorption channel 124 are isolated from each other, the desorption module 122 is separated from the first adsorption module 121, and the desorption module 122 is far away from the first adsorption channel 123. Such a setting enables the desorption module 122 to process the airflow in the desorption channel 124 so that the airflow in the desorption channel 124 reaches a preset condition, and the desorption module 122 has little or no effect on the airflow in the first adsorption channel 123. Therefore, the first adsorption module and the desorption module 122 can work independently without affecting each other, that is, the refrigeration module and the desorption module 122 of the fresh-keeping device 200 do not affect each other. Therefore, the refrigeration module and the desorption module 122 of the fresh-keeping device 200 can be controlled to work simultaneously for at least one working time, and the first adsorption module 121 is used to adsorb the preset molecules flowing into the return air channel 241 from the storage compartment 210, and at the same time, the desorption module 122 is used to make the airflow in the desorption channel 124 reach the preset condition to desorb the preset molecules in the first adsorption module 121. Compared with the configuration in which the refrigeration module and the desorption module cannot work at the same time and need to work at intervals, such a configuration avoids the need for the refrigeration module to stop working when the desorption module is working, thereby affecting the refrigeration effect of the storage compartment.

[0147] The fluid treatment device 100 in this embodiment can reasonably control the working condition of the refrigeration module according to the demand, without being affected by the working condition of the desorption module 122, which is conducive to ensuring a good refrigeration effect of the storage compartment 210. At the same time, since the first adsorption channel 123 and the desorption channel 124 are isolated from each other, the airflow flowing out of the desorption channel 124 will not flow into the storage compartment 210, thereby reducing the influence of the airflow in the desorption channel 124 on the airflow in the storage compartment 210, further ensuring a good refrigeration effect of the airflow in the storage compartment 210, that is, even in the process of the desorption module 122 desorbing the preset molecules in the first adsorption module, the refrigeration module can continue to work to ensure a good refrigeration effect of the storage compartment 210.

[0148] Among them, the desorption module 122 is connected to the inner wall and / or outer wall of the desorption channel 124. The desorption module 122 is located upstream of the first adsorption module 121. Therefore, when the desorption module 122 is working, it can make the airflow in the desorption channel 124 quickly reach the preset conditions, and blow the airflow that reaches the preset conditions to the first adsorption module 121, so that the preset molecules in the first adsorption module 121 are separated, so that the first adsorption module 121 restores good adsorption capacity. At the same time, this setting can reduce the influence of the desorption module 122 on the airflow in the first adsorption channel 123. In some embodiments, the desorption module 122 is arranged adjacent to the first adsorption module 121, and the desorption module 122 is connected to the outer wall of the first adsorption module 121 to improve the desorption effect of the desorption module 122 on the molecules adsorbed by the first adsorption module 121.

[0149] It is understandable that in order to reduce the influence of the desorption module 122 on the airflow in the first adsorption channel 123 , the desorption module 122 may be disposed on the inner wall and / or outer wall of the desorption channel 124 away from the first adsorption channel 123 .

[0150] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 includes a shell, a first adsorption module 121 is located in the shell, a first space and a second space are formed in the shell, which are respectively connected to the first adsorption channel 123 and the desorption channel 124, and the desorption module 122 is connected to the outside of the shell corresponding to the desorption channel 124. For example, the desorption module 124 can be set on the outer wall surface of the shell and connected to the second space in the shell. There is an isolation element between the first space and the second space, so as to reduce or eliminate the phenomenon of gas in the first adsorption channel 121 and the desorption channel 124 entering the shell and causing swaying, mixing, etc.

[0151] Among them, the desorption module 122 is connected to the outside of the shell, which is convenient for the disassembly and assembly of the desorption module 122 and the shell. The desorption module 122 can be directly repaired and replaced on the outside of the shell, which is convenient to operate. Compared with the desorption module being installed inside the shell and requiring the shell to be disassembled to repair and replace the desorption module 122, it is conducive to improving the efficiency of maintenance and replacement. At the same time, the desorption module 122 is connected to the outside of the shell corresponding to the desorption channel 124. Therefore, by using the desorption module 122 to work, the airflow in the desorption channel 124 can quickly reach the preset conditions, so that the preset molecules in the first adsorption module 121 connected to the desorption channel 124 are separated, so that the first adsorption module 121 restores good adsorption capacity. At the same time, the operation of the desorption module 122 does not affect the airflow state in the first adsorption channel 123, thereby ensuring that the first adsorption module 121 and the desorption module 122 can work at the same time, that is, the refrigeration module and the desorption module 122 of the fresh-keeping device 200 can operate at the same time at least at one time. The desorption module 122 may be connected to the housing by at least one of bolts, a clamping structure, a mortise and tenon structure, and an adhesive.

[0152] In some possible implementations provided by the present disclosure, for example Figure 2 As shown, the housing is provided with an adsorption inlet communicating with the first space and the first adsorption channel, and an adsorption outlet communicating with the first space and the return air channel. The first valve body 126A is provided at the adsorption inlet, and the second valve body 126B is provided at the adsorption outlet.

[0153] A partition is provided in the housing to separate the first space from the second space, wherein the first adsorption module 121 can move relative to the partition.

[0154] In some possible embodiments provided by the present disclosure, the adsorption and desorption device 120 also includes a power unit, the first adsorption module 121 is a turntable, the power unit is drivingly connected to the turntable, and the power unit drives the turntable to rotate relative to the adsorption channel 123 and the desorption channel 124.

[0155] Therefore, by utilizing the power unit, different parts of the first adsorption module 121 can be alternately connected to the first adsorption channel 123 and the desorption channel 124. Since the first adsorption module 121 connected to the first adsorption channel 123 can adsorb preset molecules in the airflow flowing through the first adsorption channel 123, at the same time, the first adsorption module 121 connected to the desorption channel 124 can desorb the preset molecules adsorbed in the first adsorption module 121 under the action of the airflow in the desorption channel 124 under preset conditions, so that the first adsorption module 121 in this area can restore its adsorption capacity. Therefore, in the process of the power unit driving the first adsorption module 121 to rotate relative to the first adsorption channel 123 and the desorption channel 124, the preset molecules in the first adsorption channel 123 can be adsorbed by different parts of the first adsorption module 121 in turn, and the desorption module 122 can desorb different parts of the first adsorption module 121 in turn to restore its adsorption capacity, thereby making the entire first adsorption module 121 gradually restore its adsorption capacity over and over again, that is, realizing the regeneration of the adsorption capacity of the first adsorption module 121, further extending the adsorption time and adsorption capacity of the first adsorption module 121, avoiding the step of replacing the first adsorption module 121, and helping to save usage costs.

[0156] Specifically, the power unit can be a driving motor (i.e., an electric drive), a pneumatic drive, a hydraulic drive, etc. Among them, the turntable can be a circular turntable. During the rotation of the turntable, the part of the turntable connected to the first adsorption channel 123 can adsorb the preset molecules in the first adsorption channel 123. When the part of the turntable rotates to be connected to the desorption channel 124, the airflow under preset conditions in the desorption channel 124 can desorb the preset molecules in the part of the turntable, thereby making the part of the turntable have the ability to adsorb the preset molecules again. Therefore, when the part of the turntable rotates again to be connected to the first adsorption channel 123, it has a good ability to adsorb the preset molecules, avoiding the situation where the adsorption capacity of the part of the turntable is saturated and cannot adsorb the preset molecules.

[0157] In the above embodiment, baffles are provided in the shell to isolate the first space and the second space in the shell, wherein the first space is connected to the first adsorption channel 123, and the second space is connected to the desorption channel 124. The provision of the baffles is conducive to isolating the first space and the second space, improving the independence of the desorption channel 124 and the first adsorption channel 123, and reducing the interconnectivity of the airflow in the desorption channel 124 and the first adsorption channel 123 in the shell, thereby allowing the desorption channel 124 and the first adsorption channel 123 to operate independently of each other, so that the first adsorption module 121 and the desorption module 122 can work independently without affecting each other.

[0158] The turntable is in sealed contact with the baffle and can rotate relative to the baffle, so that the setting of the baffle does not interfere with the movement of the turntable, and there is good sealing between the turntable and the baffle to ensure that the desorption channel 124 and the first adsorption channel 123 are independent of each other. That is to say, during the rotation of the turntable, the airflows of the first adsorption channel 123 and the desorption channel 124 are separated and kept relatively sealed after entering the shell. The circulating airflow of the first adsorption channel 123 passes through the baffle as little as possible to reach the desorption channel 124, and the circulating airflow of the desorption channel 124 also passes through the baffle as little as possible to reach the first adsorption channel 123.

[0159] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in some possible embodiments provided by the present disclosure, the adsorption and desorption device 120 further includes an air supply unit 125, which is located in the desorption channel 124, and the air supply unit 125 is used to drive the airflow to circulate between the air supply unit 125, the desorption module 122 and the first adsorption module 121. The desorption module 122 is located upstream of the first adsorption module 121, and the air supply unit 125 is located upstream of the desorption module 122, so that the air supply unit 125 blows the airflow to the first adsorption module 121 through the desorption module 122.

[0160] The air supply unit 125 may be a fan.

[0161] In some possible embodiments provided by the present disclosure, the first adsorption module 121 includes a moisture-absorbing material and / or a deodorizing material.

[0162] Among them, the hygroscopic material parts can be, for example, 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.), polymer hygroscopic agent, alkali metal aluminosilicate (X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina and other materials with hygroscopic properties. Among them, polymer hygroscopic agent is also called polymer adsorbent, which has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents.

[0163] The deodorizing material may be, for example, 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.), or a polymer deodorant.

[0164] In one embodiment, the first adsorption module 121 can be a moisture absorption and dehumidification rotating disk or a deodorization rotating disk, and the moisture absorption and dehumidification rotating disk or the deodorization rotating disk can be made of porous materials such as zeolite, molecular sieve, metal organic framework (Metal Organic Framework, MOF) material, covalent organic framework material (Covalent Organic Frameworks, COFs), nanocarbon, silicon dioxide, etc. In one embodiment, the moisture absorption and dehumidification rotating disk or the deodorization rotating disk can also be formed by filling granular solids or particles made of at least one of the above porous materials.

[0165] In one embodiment, the moisture absorption and dehumidification turntable or the deodorization turntable may be a honeycomb or corrugated turntable carrying a moisture absorber or a deodorizer, which can adsorb and desorb / desorb absorbed water vapor or odor to achieve repeated desorption and regeneration.

[0166] In one embodiment, the moisture absorption and dehumidification rotating disk or the deodorization rotating disk includes an inorganic / organic fiber carrier (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), and the fiber carrier is coated with a moisture absorbent or deodorant such as a molecular sieve, and the molecular sieve is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of airflow moisture or odor. The molecular sieve may include single crystal molecular sieves or mixed crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, and Beta molecular sieves.

[0167] In some possible embodiments provided by the present disclosure, the desorption module 122 includes at least one of the following: a heater, an ultrasonic generator, and a microwave generator.

[0168] Taking the desorption module 122 as a heating structure as an example, the desorption module 122 is used to make the airflow in the desorption channel 124 at a preset temperature to desorb the preset molecules in the first adsorption module 121. The preset temperature can be the desorption temperature of the first adsorption module 121. It can be understood that the heat of the desorption module 122 can also come from resistive heating, waste heat conducted by a heat pipe, or heat dissipation by a condenser 250. In practice, the desorption module 122 can be any one, any two, or all of a heater, an ultrasonic generator, or a microwave generator. Figures 4 to 6As shown, in some possible embodiments provided by the present disclosure, the inlet and outlet of the desorption channel 124 are both connected to the external environment, and the airflow flows unidirectionally between the first adsorption module 121, the desorption channel 124 and the desorption module 122. Specifically, the desorption channel 124 includes a first branch and a second branch, and the inlet of the first branch of the desorption channel 124 and the outlet of the second branch are both connected to the external environment. The first branch of the desorption channel 124 connects the external environment and the desorption module 122, the first adsorption module 121 is connected to the desorption module 122, and the second branch of the desorption channel 124 connects the first adsorption module 121 and the environment. Preferably, the desorption module 122 is arranged close to the first adsorption module 121. The air supply unit 125 is arranged in the first branch of the desorption channel 124, and blows the airflow to the first adsorption module 121 through the desorption module 122, and then discharges it into the environment through the second branch of the desorption channel 124.

[0169] In this embodiment, the desorption channel 124 and the external environment form an air circulation path, so that the desorption channel 124 and the first adsorption channel 123 are independent of each other. Specifically, the airflow of the external environment flows to the desorption module 122 through the inlet of the first branch of the desorption channel 124, and after being processed by the desorption module 122 to reach the preset conditions, it passes through the first adsorption module 121 connected to the desorption channel 124, and after desorbing the preset molecules adsorbed by the first adsorption module 121, it flows to the external environment from the outlet of the second branch of the desorption channel 124, that is, the airflow flowing out of the desorption channel 124 will not return to the storage compartment 210, reducing the impact of the airflow discharged through the outlet of the desorption channel 124 on the storage compartment 210 of the fresh-keeping device 200.

[0170] like Figure 3 As shown, in some possible embodiments provided by the present disclosure, the fluid processing device 100 further includes: a digestion component 128, the digestion module is arranged downstream of the desorption module, and the digestion module performs digestion treatment on the airflow flowing through it.

[0171] When the airflow flows unidirectionally between the first adsorption module 121 , the desorption channel 124 and the desorption module 122 , the outlet of the second branch of the desorption channel 124 is connected to the digestion component 128 , and the digestion component 128 digests the airflow passing therethrough.

[0172] In this embodiment, the desorption channel 124, the external environment and the digestion component 128 form a closed airflow passage, so that the desorption channel 124 and the first adsorption channel 123 are independent of each other. Specifically, the airflow of the external environment flows to the desorption module 122 through the inlet of the first branch of the desorption channel 124, and after being processed by the desorption module 122 to reach the preset conditions, it passes through the first adsorption module 121 connected to the desorption channel 124, and after desorbing the preset molecules adsorbed by the first adsorption module 121, it flows to the digestion component 128 from the outlet of the second branch of the desorption channel 124, and is discharged to the external environment after being digested by the digestion component 128, replacing the airflow being directly discharged to the external environment through the outlet of the desorption channel 124, thereby reducing the impact of the airflow discharged through the outlet of the desorption channel 124 on the external environment.

[0173] In some possible embodiments provided by the present disclosure, when the airflow circulates between the first adsorption module 121, the desorption channel 124 and the desorption module 122, the digestion module is arranged in the desorption channel 124. The airflow in the desorption channel 124 will be processed by the desorption module 122 to meet the preset conditions, and when the air supply unit 125 is working, the airflow that meets the preset conditions can flow through the first adsorption module 121 to desorb the preset molecules adsorbed by the first adsorption module 121, and the airflow flowing through the first adsorption module 121 flows into the digestion module, and after being digested by the digestion module, it is blown to the desorption module 122 again through the air supply unit 125 to enter the next cycle.

[0174] Among them, the digestion method of the digestion component 128 can be to use catalysts, enzymes, ultraviolet rays, electrolysis, thermal decomposition or chemical digestion products for digestion, or the airflow discharged from the outlet of the desorption channel 124 can be discharged into a liquid or solid solvent, and the solvent is used to dissolve the odor molecules to achieve the digestion effect. It is understandable that the digestion component 128 can be connected to the external environment to achieve the discharge of the digested gas. Specifically, taking the digestion component 128 as ultraviolet rays as an example, ultraviolet-excited titanium catalysts can be used to decompose odorous organic molecules into water and carbon dioxide to achieve the digestion of the airflow discharged from the outlet of the desorption channel 124, wherein carbon dioxide can be discharged to the external environment. It is understandable that under this setting, the digestion component 128 can also be provided with a water storage tank to accommodate the decomposed liquid.

[0175] In some possible embodiments provided by the present disclosure, the desorption device 120 further includes a sterilization module (not shown in the figure) to sterilize the airflow.

[0176] When the airflow flows unidirectionally between the first adsorption module 121, the desorption channel 124 and the desorption module 122, the inlet of the first branch of the desorption channel 124 is connected to the external environment, and the outlet of the second branch of the desorption channel 124 is connected to the sterilization module and / or the digestion module. The sterilization module sterilizes the airflow passing through it, and / or the digestion module digests the airflow passing through it and discharges it to the external environment. This improves the sterility of the airflow discharged to the external environment through the second branch of the desorption channel 124 and reduces the pollution to the external environment. In other embodiments, a sterilization module may also be provided in the first adsorption channel 123 and / or the return air channel 241.

[0177] Specifically, the airflow from the external environment flows to the desorption module 122 through the first branch of the desorption channel 124, and after being processed by the desorption module 122 to reach the preset conditions, the preset molecules adsorbed by the first adsorption module 121 are desorbed, and then flows to the sterilization module through the second branch of the desorption channel 124, and then flows to the digestion module. After being digested by the digestion module, the airflow replaces the second branch of the desorption channel 124 and is directly discharged to the external environment. Therefore, the impact of the airflow discharged through the second branch of the desorption channel 124 on the external environment can be reduced.

[0178] In some possible embodiments provided by the present disclosure, when the airflow circulates between the first adsorption module 121, the desorption channel 124 and the desorption module 122, the sterilization module and the digestion module are both arranged in the desorption channel 124. The airflow in the desorption channel 124 will be processed by the desorption module 122 to meet the preset conditions, and when the air supply unit 125 is working, the airflow that meets the preset conditions can flow through the first adsorption module 121 to desorb the preset molecules adsorbed by the first adsorption module 121, and the airflow flowing through the first adsorption module 121 flows into the sterilization module and then flows through the digestion module (or flows through the digestion module and then flows through the sterilization module), and then blown to the desorption module 122 again through the air supply unit 125 to enter the next cycle.

[0179] like Figure 3 As shown, in some possible embodiments provided by the present disclosure, the suction and desorption device 120 also includes a first filtering and purifying device 127, which is arranged on the passage between the first adsorption module 121 and the return air channel 241, and is used to purify the airflow flowing to the air inlet of the return air channel 241. Specifically, the first filtering and purifying device 127 is arranged on the passage between the turbine 160 and the return air channel 241. The provision of the first filtering and purifying device 127 can improve the cleanliness of the airflow flowing into the storage compartment 210 through the suction and desorption device 120. Specifically, the first filtering and purifying device 127 can be used to filter at least one of particles, water vapor, and oil in the gas flowing through it.

[0180] like Figure 7As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 130 includes at least one second adsorption module 131, and the second adsorption module 131 is connected to the air inlet of the gas conditioning zone 214 through a third valve assembly 132. The air pressure inside or downstream of the second adsorption module 131 is the first air pressure, and the air pressure in the gas conditioning zone 214 is the second air pressure; wherein the control device is configured to control the first air pressure to be higher than the second air pressure.

[0181] Therefore, by reasonably adjusting the on and off states of the first valve assembly 110, the second valve assembly 150, and the third valve assembly 132, the fluid driving device 140 is controlled to make the first air pressure higher than the second air pressure. In this way, the air outlet of the gas-controlled zone 214, the fluid driving device 140, at least one second adsorption module 131, and the air inlet of the gas-controlled zone 214 form a circulating airflow passage, and can ensure that the gas in the gas-controlled zone 214 is separated into airflows of preset components by the second adsorption module 131 and then returned to the gas-controlled zone 214. Therefore, the gas components of the gas-controlled zone 214 can be adjusted, so that the adjusted gas components of the gas-controlled zone 214 are conducive to extending the preservation time of the objects to be preserved and improving the preservation quality of the objects to be preserved.

[0182] Among them, the control device is configured to control the first air pressure to be higher than the second air pressure, which can ensure that the gas pressure flowing out of the second adsorption module 131 is higher than the gas pressure of the gas conditioning zone 214, and further ensure that the airflow of the preset components separated by the second adsorption module 131 can flow smoothly and reliably into the gas conditioning zone 214 to adjust the gas components of the gas conditioning zone 214.

[0183] The number of the second adsorption modules 131 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 214 to achieve regulation of different gas components in the gas conditioning zone 214, 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 the second adsorption modules 131 is at least two, at least two second adsorption modules 131 can separate different preset components in the gas. At this time, the third valve assembly 132 can be a multi-way valve, so that the third valve assembly 132 can be controlled to connect a second adsorption module 131 to the air inlet according to the type of the object to be preserved, so as to regulate the gas components in the gas conditioning zone 214 through the gas of the preset components separated by the second adsorption module 131, or control the third valve assembly 132 to connect two or more second adsorption modules 131 to the air inlet, so as to regulate the gas components in the gas conditioning zone 214 through two or more gases of preset components.

[0184] Specifically, when the number of second adsorption modules 131 is at least two and at least two gas components in the gas conditioning zone 214 need to be adjusted, one second adsorption module 131 can be used in turn to adjust the corresponding gas components, and then another second adsorption module 131 can be controlled to adjust the corresponding gas components, and so on, at least two second adsorption modules 131 can be used to adjust at least two gas components so that the gas components in the gas conditioning zone 214 meet the target information.

[0185] like Figure 3 and Figure 7 As shown, in some possible embodiments provided by the present disclosure, the second valve assembly 150 is a multi-way valve, and the second valve assembly 150 is also connected to the external environment. The control device is also configured to adjust the connection and disconnection between the fluid drive device 140 and the storage compartment 210 through the second valve assembly 150, and / or, adjust the connection and disconnection between the fluid drive device 140 and the gas conditioning zone 214 through the second valve assembly 150, and / or, adjust the connection and disconnection between the fluid drive device 140 and the external environment through the second valve assembly.

[0186] That is to say, the gas flowing into the second adsorption module 131 through the fluid driving device 140 can be the gas of the external environment, or the gas in the gas-controlled zone 214, or it can also be the common gas of the external environment and the gas-controlled zone 214. Therefore, according to the target component information of the gas ultimately required in the gas-controlled zone 214, the on-off state of the fluid driving device 140 and the gas-controlled zone 214, and the on-off state of the fluid driving device 140 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 second adsorption module 131 through the fluid driving device 140, and then flow into the gas-controlled zone 214 again after separation, so that the gas in the gas-controlled zone 214 can quickly reach the target component, and the adjustment of the gas-controlled component in the gas-controlled zone 214 can be quickly realized.

[0187] Among them, when the second valve assembly 150 connects the fluid driving device 140 with the gas-controlled zone 214, the gas flowing through the second adsorption module 131 comes from the gas-controlled zone 214, and the gas of preset components after separation by the second adsorption module 131 also flows to the gas-controlled zone 214, that is, the second adsorption module 131 separates the gas from the gas-controlled zone 214 into gas-controlled gases of preset components and then returns them to the gas-controlled zone 214, so that the second adsorption module 131 realizes the capture and release of the gas, and uses the gas of the gas-controlled zone 214 itself to directly adjust the gas components in the gas-controlled zone 214, which greatly improves the utilization rate of the gas in the gas-controlled zone 214 and reduces the waste of gas energy.

[0188] like Figure 3 and Figure 7As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 130 also includes: an exhaust device 133, the exhaust device 133 is connected to the second valve assembly 150, and the control device is also configured to adjust the connection and disconnection between the gas conditioning zone 214 and the exhaust device 133 through the second valve assembly 150.

[0189] Among them, the exhaust device 133 is connected to the external environment. The exhaust device 133 can discharge the gas in the gas-controlled area 214 and / or the storage room 210 to the external environment through the exhaust device 133, which is further conducive to the gas separated by the second adsorption module 131 to flow smoothly into the gas-controlled area 214, and / or the gas after adsorption by the first adsorption module 121 to flow smoothly into the storage room 210.

[0190] Specifically, when the second valve assembly 150 connects the fluid driving device 140 with the external environment, the first valve assembly 110 connects at least one second adsorption module 131 with the air inlet of the gas-controlled zone 214, that is, the gas in the external environment flows into the gas-controlled zone 214 after passing through the fluid driving device 140 and the second adsorption module 131. In this state, if the airflow in the gas-controlled zone 214 is closed, it will affect the level of the second air pressure. Therefore, the air outlet of the gas-controlled zone 214 is connected to the exhaust device 133 through the second valve assembly 150, so that the gas in the gas-controlled zone 214 is discharged from the exhaust device 133 to the external environment through the air outlet, thereby enabling the airflow to form a circulation passage, so that the gas in the gas-controlled zone 214 can be discharged smoothly, so as to improve the regulation efficiency of the gas components in the gas-controlled zone 214, and at the same time, enable the gas separated by the second adsorption module 131 to flow smoothly into the gas-controlled zone 214.

[0191] In the above embodiment, the exhaust device 133 is also provided with a silencer, which can reduce the noise of the gas discharged to the external environment through the exhaust device 133, reduce the impact of the noise on the user, and improve the comfort of use. Specifically, the silencer can be a silencer cotton.

[0192] Alternatively, the exhaust device 133 is made of a sound-absorbing material to reduce the noise of the gas being discharged to the external environment through the exhaust device 133 .

[0193] Alternatively, the exhaust device 133 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 133.

[0194] Specifically, the exhaust device 133 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.

[0195] like Figure 3 and Figure 7As shown, in some possible embodiments provided by the present disclosure, the first valve assembly 110 is also connected to the exhaust device 133, and the control device is further configured to adjust the connection and disconnection between the fluid driving device 140 and the exhaust device 133, and the connection and disconnection between the second adsorption module 131 and the exhaust device 133 through the first valve assembly 110. It can be understood that Figure 7 As shown, the exhaust device 133 connected to the first valve assembly 110 can be the same as the exhaust device 133 connected to the second valve assembly 150, or Figure 3 As shown, the exhaust device 133 connected to the first valve assembly 110 and the exhaust device 133 connected to the second valve assembly 150 can be provided separately.

[0196] Among them, the first valve assembly 110 connects the fluid driving device 140 with the exhaust device 133, so that when the fluid driving device 140 is connected with the air outlet of the gas-controlled zone 214, the gas in the gas-controlled zone 214 can be discharged by the exhaust device 133 after passing through the fluid driving device 140. Among them, the fluid driving device 140 can be an air compressor, so that the gas in the gas-controlled zone 214 can be pumped out through the air outlet through the air compressor, so that the gas-controlled zone 214 can be in a negative pressure state. Further, when the third valve assembly 132 is in a closed state, that is, the air inlet of the gas-controlled zone 214 is in a closed state, the gas in the gas-controlled zone 214 is sucked out by the fluid driving device 140, so that the gas-controlled zone 214 can be in a vacuum state, so as to meet the preservation of the objects to be preserved in a vacuum state, which can extend the preservation time, and further expand the scope of use of the gas-controlled device 130.

[0197] The first valve assembly 110 connects the second adsorption module 131 and the exhaust device 133 , so that after the second adsorption module 131 separates the gas of the preset components, the remaining excess gas can be discharged through the exhaust device 133 .

[0198] Specifically, the control device is also configured to control the second air pressure to be normal pressure or negative pressure through the fluid driving device 140, thereby ensuring that the first air pressure is higher than the second air pressure, so that the gas of the preset components separated by the second adsorption module 131 can flow smoothly into the gas conditioning zone 214.

[0199] In one example, the control device is configured to control the second valve assembly 150 to connect the gas outlet of the gas-controlled zone 214 with the exhaust device 133, so that the gas in the gas-controlled zone 214 is discharged through the exhaust device 133, ensuring that the preset component airflow separated by the second adsorption module 131 can smoothly enter the gas-controlled zone 214. It can be understood that in this state, the control device can also control the second valve assembly 150 to connect the fluid drive device 140 with the external environment, the first valve assembly 110 to connect the fluid drive device 140 with at least one second adsorption module 131, and the third valve assembly 132 to connect the second adsorption module 131 with the air inlet of the gas-controlled zone 214, thereby, the external environment, the second adsorption module 131 and the gas-controlled zone 214 constitute an airflow circulation system, which can keep the second air pressure at normal pressure. Among them, normal pressure can be understood as one atmospheric pressure.

[0200] In another example, the control device is configured to control the second valve assembly 150 to connect the gas-controlled zone 214 and the fluid drive device 140, and control the first valve assembly 110 to connect the fluid drive device 140 and the second adsorption module 131, and the second adsorption module 131 and the exhaust device 133, so that the gas in the gas-controlled zone 214 is separated by the second adsorption module 131 through the fluid drive device 140 and then discharged, such as returning to the gas-controlled zone 214, and the remaining gas after separation by the second adsorption module 131 is discharged through the exhaust device 133, so that the first air pressure is higher than the second air pressure, ensuring that the preset component airflow after separation by the second adsorption module 131 can smoothly enter the gas-controlled zone 214.

[0201] In another example, the control device is configured to control the second valve assembly 150 to connect the gas-controlled area 214 with the fluid drive device 140, and control the first valve assembly 110 to connect the fluid drive device 140 with the exhaust device 133, so that the gas in the gas-controlled area 214 passes through the fluid drive device 140 and then is discharged through the exhaust device 133, so that the second air pressure remains negative. Wherein, the fluid drive device 140 is an air compressor. At this time, the air inlet of the gas-controlled area 214 and the second adsorption module 131 can be controlled to be in a blocked state through the third valve assembly 132, that is, the air inlet is closed, so that the gas in the gas-controlled area 214 is sucked by the fluid drive device 140 and then discharged through the exhaust device 133, so that the gas-controlled area 214 can be in a vacuum state.

[0202] In some possible embodiments provided by the present disclosure, the second adsorption module 131 includes a second adsorption channel, and an adsorption material located in the second adsorption channel and / or connected to the second adsorption channel, wherein the second adsorption channel can be connected to the fluid driving device 140 and the air inlet of the gas conditioning zone 214, and the adsorption material is configured to separate preset components in the gas flowing through it to achieve the function of separating gas components.

[0203] Furthermore, the working form of the second adsorption module 131 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 second adsorption module 131 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 second adsorption module 131 can change its physical and chemical properties through external means, so that molecular sieves with different porosities can achieve gas separation of different components.

[0204] 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 SBA- material, and suitable metal ions can be embedded as needed to improve the performance of molecular sieve deintercalation and filtering gas molecules.

[0205] 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.

[0206] 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.

[0207] Among them, the pressure swing adsorption desorption type adsorption material can use zeolite molecular sieve as the adsorbent, and use the principle of pressure adsorption and pressure reduction desorption to adsorb and release nitrogen from the air, thereby separating oxygen. Zeolite molecular sieve is a spherical granular adsorbent with micropores on the surface and inside, which is processed through a special pore treatment process. Its pore characteristics enable it to achieve O 2 、N 2 Kinetic separation of zeolite molecular sieves for O 2 、N 2 The separation is based on the small difference in the kinetic diameters of the two gases, N 2 Molecules have a faster diffusion rate in the micropores of zeolite molecular sieves. 2 The molecular diffusion rate is slow. Water and CO in compressed air 2 The diffusion of oxygen is similar to that of nitrogen. Eventually, the gas flowing through the adsorbent material will be separated into oxygen molecules with a concentration of more than 93% ± 3%.

[0208] like Figure 2 As shown, in some possible embodiments provided by the present disclosure, the number of the suction and desorption device 120 is at least one, that is, the number of the suction and desorption devices 120 of the fluid processing device 100 can be reasonably set according to the adsorption requirements, such as the number of the suction and desorption devices 120 can be one, two, three, or other numbers. Therefore, the number of the suction and desorption devices 120 can be reasonably set according to the concentration of the odor in the storage room 210, the efficiency of treating the odor, etc. It can be understood that when the storage room 210 of the fresh-keeping device 200 includes multiple storage rooms 210, each storage room 210 can be connected to at least one suction and desorption device 120 to achieve direct treatment of the airflow of each storage room 210; or, the multiple storage rooms 210 include a first part of the storage room and a second part of the storage room, the first part of the storage room is connected to at least one suction and desorption device 120 to achieve direct treatment of the airflow of the first part of the storage room, and the second part of the storage room is connected to the first part of the storage room by airflow to indirectly achieve the treatment of the airflow of the second part of the storage room 210.

[0209] Among them, each second adsorption module 131 of the atmosphere control device 130 is separately arranged, which is convenient for individual maintenance of each second adsorption module 131 and is conducive to saving maintenance costs. At the same time, different second adsorption modules 131 can be reasonably assembled as needed to form the atmosphere control device 130 required by the preservation equipment 200, thereby expanding the scope of use and saving costs.

[0210] Among them, at least part of the second adsorption module 131 of the atmosphere control device 130 is integrated in the adsorption tower, and the second adsorption channels in the adsorption tower are separated, so that at least part of the second adsorption module 131 can be modularly designed, which is beneficial to reducing the overall volume of the atmosphere control device 130. 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, the second adsorption channels in the adsorption tower are separated, which can make the components of the airflow flowing out through each second adsorption channel different, realize the separation of airflows of different components, and improve the accuracy of airflow separation. It can be understood that all the second adsorption modules 131 can be integrated in the adsorption tower, or part of the second adsorption modules 131 can be integrated in the adsorption tower.

[0211] Among them, at least part of the second adsorption module 131 and the first adsorption module 121 are integrated in the adsorption tower, and the second adsorption channels and the first adsorption channels 123 in the adsorption tower are separated. That is to say, the adsorption and desorption device 120 and part of the gas conditioning device 130 can be integrated, or the adsorption and desorption device 120 and the entire gas conditioning device 130 can be integrated to realize the modular design of the fluid treatment device 100 and minimize the volume of the fluid treatment device 100.

[0212] like Figure 1 , Figure 3 and Figure 7 As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 130 further includes: a gas storage tank 134 , which corresponds one-to-one to the second adsorption module 131 and is connected between the corresponding second adsorption module 131 and the third valve assembly 132 .

[0213] Among them, the setting of the gas storage tank 134 allows the gas of the preset component to be stored in the corresponding gas storage tank 134 in advance by using the fluid driving device 140 and the second adsorption module 131. When the gas conditioning zone 214 needs to be supplemented with the gas conditioning of the corresponding preset component, the third valve assembly 132 is used to connect the corresponding gas storage tank 134 and the gas inlet of the gas conditioning zone 214, without the need to separate the gas, saving the time of separating the gas of the preset component, which is conducive to improving the gas conditioning efficiency of the gas conditioning zone 214. It can be understood that the second adsorption module 131 can be multiple, so that the second adsorption module 131 can be used to store different types of gases of the preset components in the corresponding gas storage tank 134 in advance to meet the needs of supplementing the gas conditioning zone 214 with gases of different preset components.

[0214] At the same time, the setting of the gas storage tank 134 can reduce the pressure drop of the preset component gas separated by the second adsorption module 131. When the separated preset component gas is maintained in the gas storage tank 134, 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 214.

[0215] The gas storage tank 134 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 134, and the gas from the second adsorption module 131 may be directly injected into the gas conditioning zone 214 through the third valve assembly 132.

[0216] Specifically, Figure 7 As shown, the second adsorption module 131 includes a second adsorption module 131A, a second adsorption module 131B, and a second adsorption module 131C. Correspondingly, the gas storage tank 134 includes a gas storage tank 134A, a gas storage tank 134B, and a gas storage tank 134C to store the gas of the preset components separated by the corresponding second adsorption module. Further, the gas storage tank 134A, the gas storage tank 134B, and the gas storage tank 134C are used to meet the needs of replenishing different preset components of gas into the gas conditioning zone 214A, the gas conditioning zone 214B, and the gas conditioning zone 214C.

[0217] In some possible embodiments provided by the present disclosure, the gas conditioning device 130 further includes: a pressurizer, which corresponds to the second adsorption module 131 one by one, and is used to pressurize the gas flowing from the corresponding second adsorption module 131 to the gas conditioning zone 214. 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 214.

[0218] It is understandable that, in some possible embodiments, the pressurizer and the gas storage tank 134 may be provided at the same time to further ensure that the first gas pressure is higher than the second gas pressure.

[0219] like Figure 3 and Figure 7 As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 130 also includes: a second filtering and purification device 135, connected between the gas storage tank 134 and the corresponding second adsorption module 131, for filtering at least one of particles, water vapor, and oil in the gas flowing through it.

[0220] The second filter purification device 135 is provided to reduce the condensed water, dust and lubricating grease in the gas path from entering the rear gas storage tank 134, and maintain the cleanliness of the gas storage tank 134 and the rear gas use area. The second filter purification device 135 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.

[0221] It is understandable that the filtering and purification device between each second adsorption module 131 and the corresponding gas storage tank 134 can be separately provided to achieve independent filtering of each component, or a second filtering and purification device 135 can be provided to filter the gas flowing from each second adsorption module 131 to the gas storage tank 134 in time-sharing multiplexing. Figure 7 The second filtering and purifying device 135 shown is used for filtering the gas flowing from each second adsorption module 131 to the gas storage tank 134 in a time-division multiplexing manner.

[0222] Furthermore, the gas conditioning device 130 may also include a filter 136, which is arranged between the second valve assembly 150 and the fluid driving device 140 to filter the gas entering the fluid driving device 140 through the second valve assembly 150, so as to reduce the impact of impurities on the reliability of the fluid driving device 140 and improve the service life and reliability of the fluid driving device 140.

[0223] like Figure 3As shown, in some possible embodiments provided by the present disclosure, the gas conditioning device 130 also includes: a gas detection device 180, which is used to detect preset molecules in the storage compartment 210 and / or to detect gas components in the gas conditioning area 214.

[0224] The setting of the gas detection device 180 can realize the detection of preset molecules of the gas in the storage room and / or the detection of the gas components in the gas conditioning zone. As a result, the control device can adjust the state of the first valve assembly 110 and the second valve assembly according to the detection result of the gas detection device 180, so as to adjust the on-off state of the suction and removal device 120 and the air outlet of the return air channel, and the on-off state of the air conditioning device 130 and the air outlet of the gas conditioning zone 214.

[0225] The gas detection device 180 may be a sensor for detecting the concentration of preset molecules in the airflow, or a sensor for detecting the concentration of gas-adjusting components, or a particle sensor or a mass spectrometer sensor, or other forms of sensors for detecting gas specific gravity. Thus, the detection result of the gas detection device 180 may indicate the proportion of preset molecules in the airflow in the storage compartment 210, and / or the proportion of preset gas-adjusting components in the gas-adjusting zone 214.

[0226] like Figures 1 to 7 As shown, an embodiment of the second aspect of the present disclosure provides a fresh-keeping device 200, including: a fluid processing device 100 of any embodiment of the first aspect. Since the fresh-keeping device 200 has all the beneficial technical effects of the above-mentioned fluid processing device 100, they will not be described one by one here.

[0227] like Figures 1 to 7 As shown, in some possible embodiments provided by the present disclosure, the fresh-keeping device 200 also includes: a refrigeration module, an air supply sub-channel 2421 for introducing the dry cold airflow passing through the refrigeration module into the storage compartment 210, and a return air channel 241 for guiding the airflow flowing out of the storage compartment 210 to flow through the refrigeration module. The control device is connected to the refrigeration module, and the control module is configured to control the refrigeration module and the desorption module 122 of the adsorption and desorption device 120 to operate simultaneously within at least one working period.

[0228] Thus, the working condition of the refrigeration module can be reasonably controlled according to the demand without being affected by the working condition of the desorption module 122, which is conducive to ensuring a good refrigeration effect of the storage compartment 210. At the same time, the arrangement of the first valve body 126A and the second valve body 126B, and / or the arrangement of the turbine 160 and the condenser 250, and / or the isolation of the first adsorption channel 123 and the desorption channel 124 from each other, so that the airflow flowing out of the desorption channel 124 will not flow into the storage compartment 210, and the airflow in the first adsorption channel 123 will not flow into the storage compartment 210 or will flow into the storage compartment 210 after cooling, thereby reducing the influence of the hotter airflow in the adsorption and desorption device 120 on the low-temperature airflow in the storage compartment 210, and further ensuring a good refrigeration effect of the airflow in the storage compartment 210.

[0229] like Figures 4 to 6 As shown, in some possible embodiments provided by the present disclosure, the storage compartment 210 includes a freezer compartment 211, and the refrigeration module includes an evaporator 270, a compressor 280, a condenser 250, and a throttling element 260 which are connected in sequence through a refrigerant pipeline to form a circulation path. The evaporator 270 is at least located in the freezer compartment 211, and the control module is connected to the compressor 280 to control the start and stop state of the compressor 280, and to enable the compressor 280 and the desorption module 122 to operate simultaneously for at least one working period.

[0230] The evaporator 270 is located in the freezing chamber 211 to achieve refrigeration of the freezing chamber 211. Specifically, the control device controls the compressor 280 of the refrigeration module to work, so that the refrigerant flows between the refrigerant circulation path formed by the evaporator 270, the compressor 280, the condenser 250, and the throttling element 260 to cool the evaporator 270, thereby reducing the temperature of the freezing chamber 211 and achieving refrigeration of the freezing chamber 211.

[0231] It is understandable that when the storage compartment 210 also includes other compartments, the evaporator 270 can also be located in other storage compartments 210 to cool the corresponding storage compartments 210, or, only the evaporator 270 in the freezer compartment 211 can be used to indirectly cool other storage compartments 210 through the air supply sub-channel 2421.

[0232] like Figure 4As shown, in some possible embodiments provided by the present disclosure, the storage compartment 210 also includes a refrigerated compartment 212, the freezer compartment 211 is provided with a first air inlet and a first air outlet, the refrigerated compartment 212 is provided with a second air inlet and a second air outlet, the air supply sub-channel 2421 connects the first air outlet and the second air inlet, the second air outlet is connected to the first adsorption module 121 of the adsorption / desorption device 120 through the first adsorption channel 123, and the return air channel 241 connects the first adsorption module 121 of the adsorption / desorption device 120 and the first air inlet; wherein, the fresh-keeping device 200 also includes a fan 290 located in the air supply sub-channel 2421 or the return air channel 241.

[0233] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezing compartment 211 and a refrigerating compartment 212. Since the air supply sub-channel 2421 is connected to the first air outlet of the freezing compartment 211 and the second air inlet of the refrigerating compartment 212, and the return air channel 241 is connected to the first adsorption module 121 and the first air inlet of the freezing compartment 211, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezing compartment 211 from the air supply sub-channel 2421 to the refrigerating compartment 212, and the air flow in the refrigerating compartment 212 enters the first adsorption module 121 through the air supply channel 242, the fluid driving device 140, and the first adsorption channel 123, and then flows back into the freezing compartment 211 through the return air channel 241, thereby realizing the circulation of air flow.

[0234] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 through the air supply sub-channel 2421 to the refrigerating compartment 212 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212. Among them, the airflow flowing from the cold storage compartment 212 into the air supply channel 242 will carry preset molecules, which can be odor molecules and / or moisture molecules. Since the first adsorption channel 123 of the fluid treatment device 100 is connected to the first adsorption module 121, the preset molecules in the airflow flowing from the cold storage compartment 212 into the air supply channel 242 can be adsorbed by the first adsorption module 121, and then the treated airflow flows into the freezing compartment 211, and flows into the cold storage compartment 212 again through the air supply sub-channel 2421, thereby achieving the treatment of the airflow in the freezing compartment 211 and the cold storage compartment 212, such as being able to reduce the content of odor molecules and / or moisture molecules in the airflow in the freezing compartment 211 and the cold storage compartment 212, and achieving the effect of removing odor and / or dehumidification. It can be understood that the fluid treatment device 100 in this embodiment can be understood as a single cycle mode, and the fresh-keeping device 200 in this embodiment is air-cooled refrigeration.

[0235] Among them, the fan 290 can be located in the return air channel 241, or in the air supply sub-channel 2421, or in the air supply channel 242, so that the airflow in the freezing compartment 211, the air supply sub-channel 2421, the refrigerating compartment 212, the air supply channel 242, the fluid driving device 140, the first adsorption channel 123, the first adsorption module 121, and the return air channel 241 forms a circulation path.

[0236] It can be understood that, under the action of the power unit, the part of the first adsorption module 121 adsorbed with the preset molecules can move to connect with the desorption channel 124. Thus, under the action of the desorption module 122 and the air supply unit 125, the preset molecules are desorbed by the airflow under preset conditions in the desorption channel 124 and then discharged from the external environment or sent to the digestion component 128 along with the airflow.

[0237] like Figure 5 As shown, in some possible embodiments provided by the present disclosure, the storage room 210 also includes a variable temperature room 213, and the variable temperature room 213 is provided with a third air inlet and a third air outlet. The third air inlet is connected to the air supply sub-channel 2421 through a pipeline, and the third air outlet is connected to the suction and removal device 120 of the fluid processing device 100.

[0238] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezer compartment 211, a refrigerator compartment 212 and a temperature-variable compartment 213. Since the air supply sub-channel 2421 connects the first air outlet of the freezer compartment 211 and the second air inlet of the refrigerator compartment 212, the third air inlet of the temperature-variable compartment 213 is connected to the air supply sub-channel 2421 through a pipeline, the third air outlet of the temperature-variable compartment 213 is connected to the suction and desorption device 120, and the second air outlet of the refrigerator compartment 212 is connected to the suction and desorption device 120. Therefore, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezing chamber 211 and flows from the air supply sub-channel 2421 to the refrigerating chamber 212 and the temperature-changing chamber 213, and the airflow in the refrigerating chamber 212 and the temperature-changing chamber 213 enters the first adsorption module 121 through the air supply channel 242, the fluid driving device 140, and the first adsorption channel 123, and then flows back into the freezing chamber 211 through the return air channel 241, thereby realizing the circulation of airflow.

[0239] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 through the air supply channel 242 to the refrigerating compartment 212 and the temperature-changing compartment 213 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212 and the temperature-changing compartment 213. Among them, the airflow flowing into the air supply channel 242 from the refrigerating compartment 212 and the temperature-changing compartment 213 will carry preset molecules, which may be odor molecules and / or moisture molecules. Since the first adsorption channel 123 of the fluid treatment device 100 is connected to the first adsorption module 121, the preset molecules in the airflow flowing into the air supply channel 242 from the refrigerating compartment 212 and the temperature-changing compartment 213 can be adsorbed. Then, the treated airflow flows into the freezing compartment 211 through the return air channel 241, and flows into the refrigerating compartment 212 and the temperature-changing compartment 213 again through the air supply sub-channel 2421, thereby achieving the treatment of the airflow in the freezing compartment 211, the refrigerating compartment 212, and the temperature-changing compartment 213, such as reducing the content of odor molecules and / or moisture molecules in the airflow in the freezing compartment 211, the refrigerating compartment 212, and the temperature-changing compartment 213, thereby achieving the effect of removing odor and / or dehumidification. It can be understood that the fluid processing device 100 in this embodiment can be understood as a double circulation method, and the fresh-keeping equipment 200 in this embodiment can be understood as air-cooled refrigeration.

[0240] The fan 290 may be located in the return air channel 241, in the air supply sub-channel 241, or in the air supply channel 242, so that the airflow in the freezing compartment 211, the air supply sub-channel 2421, the refrigerating compartment 212 and / or the temperature-changing compartment 213, the air supply channel 242, the first adsorption channel 123, the first adsorption module 121, and the return air channel 241 forms a circulation path. It is understandable that the compressor 280 and the fan 290 may work synchronously.

[0241] It can be understood that the part of the first adsorption module 121 adsorbed with the preset molecules can move to communicate with the desorption channel 124. Thus, under the action of the desorption module 122 and the air supply part 125, the preset molecules are desorbed by the airflow under preset conditions in the desorption channel 124 and then discharged from the external environment or sent to the digestion component 128 along with the airflow.

[0242] like Figure 6As shown, in some possible embodiments provided by the present disclosure, the storage compartment 210 also includes a refrigerated compartment 212, the freezer compartment 211 is provided with a first air inlet and a first air outlet, the refrigerated compartment 212 is provided with a second air inlet, a second air outlet, a third air inlet, and a third air outlet, the air supply sub-channel 2421 connects the first air inlet and the second air inlet, the second air outlet is connected to the suction and desorption device 120, and the return air channel 241 includes a first sub-duct 2411 connecting the suction and desorption device 120 and the third air inlet, and a second sub-duct 2412 connecting the third air outlet and the first air inlet; wherein, the fresh-keeping device 200 also includes a fan 290 located on the first sub-duct 2411.

[0243] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezer compartment 211 and a refrigerator compartment 212. Since the air supply sub-channel 2421 connects the first air outlet of the freezer compartment 211 and the second air inlet of the refrigerator compartment 212, the second air outlet is connected to the first adsorption module 121 of the suction and desorption device 120, the first sub-duct 2411 of the return air channel 241 connects the first adsorption module 121 and the third air inlet of the refrigerator compartment 212, and the second sub-duct 2412 of the return air channel 241 connects the third air outlet of the refrigerator compartment 212 and the first air inlet of the freezer compartment 211. Thus, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezing chamber 211 from the air supply sub-channel 2421 to the refrigerating chamber 212, and the air flow in the refrigerating chamber 212 enters the first adsorption module 121 through the air supply channel 242, the fluid driving device 140, and the first adsorption channel 123, and then flows back into the refrigerating chamber 212 through the first sub-channel 2411 of the return air channel 241, and returns to the freezing chamber 211 through the second sub-channel 2412 of the return air channel 241, thereby realizing the circulation of air flow. It can be understood that this kind of fresh-keeping device 200 can be understood as a direct cooling refrigeration method.

[0244] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 and the air supply channel 242 to the refrigerating compartment 212 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212. Among them, the airflow flowing from the refrigerated compartment 212 into the air supply channel 242 will carry preset molecules, which can be odor molecules and / or moisture molecules. Since the first adsorption channel 123 of the fluid treatment device 100 is connected to the first adsorption module 121, the preset molecules in the airflow flowing from the refrigerated compartment 212 into the air supply channel 2421 can be adsorbed, and then the treated airflow flows into the refrigerated compartment 212 and flows into the freezing compartment 211 again through the second sub-air duct 2412, thereby achieving the treatment of the airflow in the refrigerated compartment 212 and the freezing compartment 211, such as being able to reduce the content of odor molecules and / or moisture molecules in the airflow in the refrigerated compartment 212 and the freezing compartment 211, and achieving the effect of removing odor and / or dehumidification. It can be understood that the fluid treatment device 100 in this embodiment can be understood as a single-cycle method.

[0245] Among them, the fan 290 can be located in the first sub-air duct 2411, can be located in the air supply sub-channel 2421, and can be located in the air supply channel 242, so that the airflow in the freezing compartment 211, the air supply sub-channel 2421, the refrigerating compartment 212, the air supply channel 242, the fluid driving device 140, the first adsorption channel 123, the first adsorption module 121, the first sub-air duct 2411, and the second sub-air duct 2412 forms a circulation passage.

[0246] It can be understood that the part of the first adsorption module 121 adsorbed with the preset molecules can move to communicate with the desorption channel 124. Thus, under the action of the desorption module 122 and the air supply part 125, the preset molecules are desorbed by the airflow under preset conditions in the desorption channel 124 and then discharged from the external environment or sent to the digestion component 128 along with the airflow.

[0247] Furthermore, if Figure 1 and Figure 2 As shown, the fresh-keeping device 200 also includes: a box body 220, and a door body 230 for opening and closing the box body 220, a storage compartment 210 is arranged in the box body 220, the suction and desorption device 120 and the atmosphere control device 130 are arranged on the box body 220 and / or the door body 230, the elution device is located inside and / or outside the fresh-keeping device 200; the atmosphere control device 130 is located outside the fresh-keeping device 200.

[0248] The suction and desorption device 120 and the gas-adjusting device 130 can be arranged on the box body 220, or on the door body 230, or the suction and desorption device 120 and the gas-adjusting device 130 can be arranged on the box body 220 and on the door body 230, respectively. The suction and desorption device 120 can be located outside the box body 220, or inside the box body 220, or a plurality of suction and desorption devices 120 can be arranged inside and outside the box body 220, respectively, thereby expanding the setting range of the gas device. The gas-adjusting device 130 suction and desorption device 120 can be located outside the box body 220 to achieve the adjustment of the components of the gas in the gas-adjusting zone 214, and at the same time, facilitate the connection between the fluid-driving device 140 and the external environment, and also facilitate the connection between the exhaust device 133 and the external environment.

[0249] In some possible embodiments provided by the present disclosure, the distance between the fluid treatment device 100 and the top wall of the box 220 is 18 cm to 25 cm; the distance between the fluid treatment device 100 and the side wall of the box 220 is 18 cm to 25 cm; the distance between the fluid treatment device 100 and the rear wall of the box 220 is 18 cm to 25 cm.

[0250] Among them, by reasonably setting the distance between the fluid handling 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 is possible to ensure that the gas-fluid handling device 100 is reliably connected to the storage compartment 210, and at the same time, it is possible to minimize the impact of the fluid handling device 100 on the external dimensions and installation dimensions of the refrigerator. Specifically, the distance between the fluid handling device 100 and the top wall of the box 220 can be 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the fluid handling device 100 and the side wall of the box 220 is 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the fluid handling 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 fluid treatment 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.

[0251] In some possible embodiments provided by the present disclosure, the third valve assembly 132 of the fluid processing device 100 is arranged close to the condenser 250, and the fluid driving device 140 of the fluid processing device 100 is arranged in a spherical space with the compressor 280 as the center and a preset size as the radius.

[0252] 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 214 or transmits dry cold air flow to the air-conditioning zone 214 through a suitable air duct to keep the temperature of the air-conditioning zone 214 low. Thus, the low-temperature gas is used to extend the preservation time of the objects to be preserved in the air-conditioning zone 214.

[0253] The third valve assembly 132 is disposed close to the condenser 250 , so that the air input into the air conditioning zone 214 by the air conditioning device 130 can be kept at a low temperature.

[0254] Among them, the fluid driving device 140 is arranged in a spherical space with the compressor 280 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 140 and the compressor 280 to arrange the pipes connected to the fluid driving device 140 and the compressor 280. At the same time, space is provided for the maintenance of the fluid driving device 140 and the compressor 280, which is convenient for user operation.

[0255] In the above embodiment, 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 single-opening door body, the preset size is 650mm to 750mm. Specifically, the preset size can be 650mm, 700mm, 750mm, or other sizes that meet the requirements.

[0256] Alternatively, when the door body 230 is located on the side of the box body 220, that is, the refrigerator is a side-opening door refrigerator, when the door body 230 is a double-door body, the preset size is 1150mm to 1250mm. Specifically, the preset size can be 1150mm, 1200mm, 1250mm, or other sizes that meet the requirements.

[0257] Alternatively, when the door body 230 is located at the top of the box body 220, such as the refrigerator is a freezer, the door body 230 is an upward opening door body, and the preset size is 2400mm to 2600mm. Specifically, the preset size can be 2400mm, 2500mm, 2600mm, or other sizes that meet the requirements.

[0258] The third aspect of the present disclosure is as follows Figure 8 As shown, a control method of a fresh-keeping device 200 is provided, the fresh-keeping device 200 includes the fresh-keeping device 200 of any embodiment of the second aspect, and the control method includes:

[0259] Control the first valve assembly 110 to selectively adjust the on / off state between the suction and desorption device 120 and the storage room 210; and / or selectively adjust the on / off state between the gas-conditioning device 130 and the gas-conditioning zone 214, so that the gas flows through the suction and desorption device 120 and returns to the storage room 210, and / or the gas flows through the gas-conditioning device 130 and returns to the gas-conditioning zone 214.

[0260] In this embodiment, according to the processing requirements of the preset molecules in the airflow in the storage room 210 and the requirements of the gas components in the gas conditioning zone 214, the storage room 210 can be selectively connected with the adsorption and desorption device 120 to adsorb the preset molecules in the airflow in the storage room 210, and / or the gas conditioning zone 214 can be connected with the gas conditioning device 130 to adjust the gas components in the gas conditioning zone 214, thereby realizing the functional diversification of the fluid processing device 100, expanding the use scope of the fluid processing device 100, and helping to improve the user's satisfaction.

[0261] 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.

[0262] Based on the preset molecular information of the storage compartment 210 meeting the first preset requirement, controlling the first valve assembly 110 to connect the adsorption device 120 with the storage compartment 210, so that the gas in the storage compartment 210 flows through the adsorption device 120 and then returns to the storage compartment 210; and / or

[0263] Based on the fact that the current information of the gas composition in the gas conditioning zone 214 does not meet the second preset requirement, the preset gas is controlled to enter the gas conditioning zone 214 .

[0264] In this embodiment, when the preset molecule information of the storage compartment 210 reaches the first preset requirement, it indicates that the preset molecule in the storage compartment 210 needs to be adsorbed, and thus, the first valve assembly 110 can be controlled to connect the adsorption device 120 with the storage compartment 210, so that the gas in the storage compartment 210 flows through the adsorption device 120 and returns to the storage compartment 210. The first preset requirement may be a percentage, concentration, etc. of the preset molecule, such as the first preset requirement may be 30% to 60% of the percentage of the gas occupied by the preset molecule, etc.

[0265] Among them, the current information of the gas components in the gas-controlled zone 214 can indicate the current situation of the gas components in the gas-controlled zone 214, and the second preset requirement can be a gas component that can prolong the preservation time of the object to be preserved. Therefore, when the current information of the gas components in the gas-controlled zone 214 does not meet the second preset requirement, it means that the current gas components in the gas-controlled zone 214 cannot prolong the preservation time of the object to be preserved. Therefore, the first valve assembly 110 is controlled to connect the gas-controlled device 130 with the gas-controlled zone 214, and the first air pressure is controlled to be higher than the second air pressure, so that the gas flows through the gas-controlled device 130 into the gas-controlled zone 214, and then the gas components in the gas-controlled zone 214 can be adjusted, so that the gas-controlled components in the gas-controlled zone 214 can quickly reach the second preset requirement, so as to prolong the preservation time of the object to be preserved in the gas-controlled zone 214 and improve the preservation quality of the object to be preserved. Among them, the second preset requirement can be the percentage of nitrogen content, the percentage of carbon dioxide content, and the like.

[0266] 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.

[0267] The refrigeration module of the fresh-keeping equipment and the desorption module of the adsorption and desorption device are controlled to operate simultaneously within at least one working time.

[0268] In this embodiment, the first valve body 126A and the second valve body 126B are arranged to isolate the first adsorption module 121 of the adsorption / desorption device 120 from the storage compartment 210, and / or the turbine 160 and the radiator 170 are arranged to cool the airflow in the first adsorption module 121 and flow into the storage compartment 210, and / or the first adsorption channel 123 and the desorption channel 124 are isolated from each other, and the desorption module 122 is arranged separately from the first adsorption module 121, so that the high-temperature gas in the desorption channel 124 does not flow into the first adsorption channel 123. Therefore, the refrigeration module and the desorption module 122 of the fresh-keeping device 200 can be controlled to work simultaneously for at least one working time, and the desorption module 122 is used to make the airflow in the desorption channel 124 reach the preset condition to desorb the preset molecules in the first adsorption module 121, and at the same time, the refrigeration module is used to refrigerate the storage compartment 210 to maintain a low temperature. Compared with the configuration in which the refrigeration module and the desorption module 122 cannot work at the same time and need to work at intervals, this configuration avoids the need for the refrigeration module to stop working when the desorption module 122 is working, thereby affecting the refrigeration effect of the storage compartment 210. The fluid treatment device 100 in this embodiment can reasonably control the working condition of the refrigeration module according to demand, without being affected by the working condition of the desorption module 122, which is conducive to ensuring a good refrigeration effect of the storage compartment 210.

[0269] It can be understood that the control device can control the air supply part 125 and the desorption module 122 of the adsorption and desorption device 120 to work synchronously, so that when the desorption module 122 works to process the airflow in the desorption channel 124 to meet the preset conditions, the air supply part 125 can work to make the airflow that meets the preset conditions flow through the first adsorption module 121 and then flow out from the outlet of the desorption channel 124, so as to desorb the preset molecules adsorbed by the first adsorption module 121 connected to the desorption channel 124, so as to ensure a good desorption effect.

[0270] Among them, the control device can control the power unit and the desorption module 122 of the adsorption and desorption device 120 to work synchronously, and the power unit is used to drive the first adsorption module 121 to rotate relative to the first adsorption channel 123 and the desorption channel 124, thereby enabling the part of the first adsorption module 121 connected to the first adsorption channel 123 and the part connected to the desorption channel 124 to be alternately exchanged. In this way, when the desorption module 122 is working, the desorption treatment of different parts of the first adsorption module 121 can be realized in turn, so that the entire first adsorption module 121 can gradually restore the adsorption capacity over and over again, that is, the adsorption capacity regeneration of the first adsorption module 121 is realized, and the adsorption time and adsorption capacity of the first adsorption module 121 are further extended. Compared with the first adsorption module 121 whose adsorption capacity cannot be regenerated, the steps of replacing the first adsorption module 121 are simplified, which is beneficial to saving usage costs.

[0271] It is understood that in some embodiments, the air supply unit 125 is opened for a preset time relative to the desorption module 122, wherein the preset time can be 30s to 300s, such as 30s, 60s, 120s, 300s or other time, thereby ensuring that the air supply unit 125 starts working only after the desorption module 122 processes the airflow in the desorption channel 124 to meet the preset conditions, ensuring that the airflow in the desorption channel 124 flowing through the first adsorption module 121 is the airflow that meets the preset conditions, so as to ensure a good desorption effect. It is understood that in this case, the air supply unit 125 and the desorption module 122 can be controlled to stop working at the same time.

[0272] 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.

[0273] Based on the adsorption capacity of the first adsorption module 121 communicating with the first adsorption channel 123 satisfying the first preset condition, the desorption module 122 is controlled to start working.

[0274] Among them, when the adsorption capacity of the first adsorption module 121 connected to the first adsorption channel 123 meets the first preset condition, it means that the adsorption capacity of the first adsorption module 121 connected to the first adsorption channel 123 is low, and there is a situation where the adsorption capacity is insufficient, close to saturation or saturated, and the preset molecules cannot be effectively adsorbed. At this time, the desorption module 122 can be controlled to work. It can be understood that the power unit and the air supply unit 125 can be controlled to work synchronously to rotate the part of the first adsorption module 121 connected to the first adsorption channel 123 to be connected to the desorption channel 124, and the desorption module 122 is used to process the airflow in the desorption channel 124 to the preset condition to achieve the adsorption treatment of the first adsorption module 121, so as to improve the adsorption capacity of this part of the first adsorption module 121, thereby ensuring that the entire first adsorption module 121 has good adsorption capacity.

[0275] 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.

[0276] Based on the adsorption capacity of the first adsorption module 121 communicating with the first adsorption channel 123 satisfying the second preset condition within the first preset time period, the desorption module 122 is controlled to stop working.

[0277] Among them, when the adsorption capacity of the first adsorption module 121 connected to the first adsorption channel 123 meets the second preset condition within the first preset time, it means that the first adsorption module 121 connected to the first adsorption channel 123 has good adsorption capacity within a certain period of time. It can be understood that the adsorption capacity of the first adsorption module 121 that meets the second preset condition is greater than the adsorption capacity of the first adsorption module 121 that meets the first preset condition. At this time, the desorption module 122 can be controlled to stop working to save energy consumption.

[0278] The first preset time length may be 10s to 300s. Specifically, the first preset time length may be 10s, 30s, 60s, 120s, 300s, or other time lengths.

[0279] For example, when the adsorption capacity of the first adsorption module 121 connected to the first adsorption channel 123 satisfies the second preset condition within the first preset time, it means that the first adsorption module 121 connected to the first adsorption channel 123 has good adsorption capacity. At this time, the preset molecules of the airflow in the first adsorption channel 123 are small, and the first adsorption module 121 cannot reach the saturation state for a long time. At this time, the desorption module 122 can be controlled to stop working to save energy consumption.

[0280] 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.

[0281] Based on the working time of the desorption module 122 reaching the second preset time, the desorption module 122 is controlled to stop working.

[0282] The second preset time length can ensure that the entire first adsorption module 121 has good adsorption capacity, that is, the first adsorption module 121 may work for a long time to reach a saturated state. At this time, the desorption module 122 can be controlled to stop working to save energy consumption.

[0283] Specifically, the second preset time length may be 600s to 6000s. Specifically, the second preset time length may be 600s, 1000s, 2000s, 3000s, 6000s or other time lengths.

[0284] 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, controlling the preset gas to enter the gas conditioning zone 214 may also include the following methods and steps.

[0285] Control the second valve assembly 150 to connect the air outlet of the gas-controlled zone 214 with the fluid driving device 140, control the first valve assembly 110 to connect the fluid driving device 140 with the target second adsorption module 131, and connect the target second adsorption module 131 with the exhaust device 133 of the gas-controlled device 130, and the third valve assembly 132 to connect the target second adsorption module 131 with the air inlet of the gas-controlled zone 214.

[0286] Among them, the target second adsorption module 131 is the second adsorption module 131 in the second adsorption module 131 that matches the second preset requirement. If the second preset requirement includes the nitrogen ratio, the target second adsorption module 131 may include a second adsorption module 131 capable of separating nitrogen from the gas flowing through it. If the second preset requirement includes the nitrogen ratio and the oxygen ratio, the target second adsorption module 131 may include a second adsorption module 131 capable of separating nitrogen from the gas flowing through it, and a second adsorption module 131 capable of separating oxygen from the gas flowing through it, and so on, which are not listed one by one in the present disclosure.

[0287] In this embodiment, by adjusting the on / off states of the first valve assembly 110, the second valve assembly 150, and the third valve assembly 132, the gas outlet of the gas-controlled zone 214 is connected to the fluid driving device 140, the fluid driving device 140 is connected to the target second adsorption module 131, the target second adsorption module 131 is connected to the exhaust device 133, and the target second adsorption module 131 is connected to the gas inlet of the gas-controlled zone 214. Thus, the gas in the gas-controlled zone 214 is separated by the target second adsorption module 131 through the fluid driving device 140 and then returned to the gas-controlled zone 214, so as to adjust the gas components in the gas-controlled zone 214, and the remaining gas after separation by the second adsorption module 131 is discharged through the exhaust device 133. Among them, the first gas pressure is higher than the second gas pressure, ensuring that the preset component gas flow separated by the second adsorption module 131 can smoothly enter the gas-controlled zone 214.

[0288] 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, controlling the preset gas to enter the gas conditioning zone may also include the following methods and steps.

[0289] Control the second valve assembly 150 to connect the air outlet of the gas-controlled zone 214 with the exhaust device 133, and connect the fluid-driving device 140 with the external environment; control the first valve assembly 110 to connect the fluid-driving device 140 with the target second adsorption module 131, and connect the target second adsorption module 131 with the exhaust device 133; the third valve assembly 132 connects the target second adsorption module 131 with the air inlet of the gas-controlled zone 214.

[0290] In this embodiment, by adjusting the states of the first valve assembly 110, the second valve assembly 150, and the third valve assembly 132, the gas outlet of the gas-controlled zone 214 is connected to the exhaust device 133, the fluid driving device 140 is connected to the external environment, the fluid driving device 140 is connected to the target second adsorption module 131, the target second adsorption module 131 is connected to the exhaust device 133, and the target second adsorption module 131 is connected to the gas inlet of the gas-controlled zone 214. Thus, the gas in the gas-controlled zone 214 is discharged through the exhaust device 133, the gas in the external environment is separated by the target second adsorption module 131 after passing through the fluid driving device 140 and then returned to the gas-controlled zone 214, so as to adjust the gas components in the gas-controlled zone 214, and the remaining gas after separation by the second adsorption module is discharged through the exhaust device 133. Among them, the first air pressure is higher than the second air pressure, ensuring that the preset component airflow after separation by the second adsorption module can smoothly enter the gas-controlled zone 214.

[0291] It is understandable that in other embodiments, the gas conditioning device 130 can also determine the gas injection time of each target second adsorption module 131 according to the second preset requirement. Specifically, the gas component proportion of the conventional atmosphere, the gas component target information of the gas conditioning zone 214, the loss of each component gas during the discharge of the conventional gas through the gas outlet of the gas conditioning zone 214, and the increment of each component gas flowing into the gas conditioning zone 214 through the gas inlet of the gas conditioning zone 214 can be combined with the above factors to determine the gas injection gas length of the fluid separated by each target second adsorption module 131 injected into the gas conditioning zone 214 when the gas component of the gas conditioning zone 214 reaches the second preset requirement from the current information. Then, the on-off state of the first valve assembly 110, the second valve assembly 150, and the third valve assembly 132 are adjusted to inject the fluid separated by the target second adsorption module 131 into the gas conditioning zone 214, and adjust the gas component of the gas conditioning zone 214.
