[0025] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following embodiments are combined with the attached Figure 1 to the attached Figure 2 to specifically elaborate on the technical solutions provided by the present utility model, but the following content is not a limitation of the present utility model.

[0026] Figure 1 The structural diagram of an embodiment of the air duct structure of an intelligent micro archives room of the present utility model; Figure 2 The structural diagram of the air duct structure of an intelligent micro archives room of a preferred embodiment of the present utility model after opening the protective cover. As Figure 1 and Figure 2 shown, the air duct structure of the intelligent micro archives room provided in this embodiment includes: main cabinet 1, sub-cabinet 2, intake three-way joint 12 and cut-off valve 3.

[0027] Specifically, a constant temperature and humidity machine 11 is arranged in the main cabinet 1. It should be noted that the constant temperature and humidity machine 11 includes but is not limited to the constant temperature and humidity machines 11 that can be directly purchased on the market. The appropriate constant temperature and humidity machine 11 can be selected according to actual usage requirements, which belongs to the common knowledge in the field. Therefore, its specific structure and working principle will not be elaborated here.

[0028] Specifically, a plurality of sub-cabinets 2 are provided, and the number of sub-cabinets 2 can be selected according to the size of the storage space required. During installation, a plurality of sub-cabinets 2 are all arranged beside the main cabinet 1 and extend along the side direction of the main cabinet 1, so that the main cabinet 1 and the sub-cabinets 2 are arranged in a line, realizing the side-by-side arrangement of the main cabinet 1 and a plurality of sub-cabinets 2, avoiding the problem that a large space is required to open the cabinet door, which affects the arrangement of the sub-cabinets 2, making the space utilization more reasonable, and thus enabling more sub-cabinets 2 to be arranged in a limited space, maximizing the storage space. At this time, each sub-cabinet 2 has a storage cavity, that is, each sub-cabinet 2 is a cabinet for storing archives and other materials, and the storage space can be expanded by expanding the number of assembled sub-cabinets 2, with a more flexible structure and better adaptability.

[0029] Specifically, several intake three-way connectors 12 are provided, and intake three-way connectors 12 are provided on both the main cabinet 1 and each sub-cabinet 2. During installation, one interface of the intake three-way connector 12 on the main cabinet 1 is connected to the air supply port of the constant temperature and humidity machine 11. At the same time, one interface of each intake three-way connector 12 on each sub-cabinet 2 is connected to its own storage cavity, so that the gas with suitable temperature and humidity generated by the constant temperature and humidity machine 11 can be discharged through the intake three-way connector 12 on the main cabinet 1. At the same time, the other two interfaces of the intake three-way connector 12 of the sub-cabinet 2 located beside the main cabinet 1 or in the middle of several sub-cabinets 2 are respectively connected to the intake three-way connector 12 of the main cabinet 1 or the intake three-way connector 12 of the adjacent sub-cabinet 2. That is, the other two interfaces of the intake three-way connector 12 on the sub-cabinet 2 beside the main cabinet 1 are respectively connected to the intake three-way connector 12 on the main cabinet 1 and the three-way intake connector on another sub-cabinet 2, and the other two interfaces of the intake three-way connector 12 of the sub-cabinet 2 located between two sub-cabinets 2 are respectively connected to the intake three-way connectors 12 on the adjacent two sub-cabinets 2. In addition, after one interface of the intake three-way connector 12 of the outermost sub-cabinet 2 is connected to the intake three-way connector 12 of the adjacent sub-cabinet 2, a cover 121 is installed on the remaining interface, which can not only realize the series connection of the intake three-way connectors 12 on several sub-cabinets 2 on the same side and be connected to the intake three-way connector 12 on the main cabinet 1 after the series connection, but also seal the interface of the intake three-way connector 12 that is not connected to other intake three-way connectors 12 through the cover 121, ensuring the closure of the intake circuit, that is, realizing the connection between the constant temperature and humidity machine 11 in the main cabinet 1 and the storage cavity of each sub-cabinet 2, providing conditions for adjusting the temperature and humidity of the storage cavity in each sub-cabinet 2, and at the same time meeting the adjustment of the storage cavities of multiple sets of sub-cabinets 2 by one set of constant temperature and humidity machine 11, improving the utilization efficiency of the constant temperature and humidity machine 11 and reducing the manufacturing and use costs.

[0030] Specifically, a cut-off valve 3 is provided on the pipeline where the intake three-way connector 12 of each sub-cabinet 2 is connected to its own storage cavity. That is, when the gas with suitable temperature and humidity transported by the constant temperature and humidity machine 11 of the main cabinet 1 enters the storage cavity of the corresponding sub-cabinet 2, the on-off control can be realized through the cut-off valve 3. That is, when the temperature and humidity in the current sub-cabinet 2 storage cavity are within the preset range, the gas sent from the main cabinet 1 can be blocked through the cut-off valve 3, avoiding waste of resources. At this time, when the temperature and humidity in the storage cavity are outside the preset range, the corresponding cut-off valve 3 can be opened to allow the gas with suitable temperature and humidity provided by the main cabinet 1 to enter the storage cavity of the corresponding sub-cabinet 2, realizing the adjustment of the temperature and humidity of the storage cavity, so as to meet the use requirements of constant temperature and humidity, that is, realizing the independent adjustment of the temperature and humidity of each sub-cabinet 2, which is not only convenient for adjustment, but also can avoid waste of resources, and the structural design is more reasonable.

[0031] More specifically, an exhaust port 21 communicating with its own storage cavity is provided on each cabinet 2, so that the gas in the storage cavity can be directly discharged through the exhaust port 21, that is, the gas replaced in the storage cavity is directly discharged into the atmosphere to realize gas external circulation. At this time, a control valve is provided on the exhaust port 21 of each cabinet 2, and the on-off of the exhaust port 21 is controlled by the control valve to ensure that the exhaust port 21 is opened only during use and the storage cavity can maintain a sealed state under normal circumstances, and the structural design is more reasonable.

[0032] More specifically, the cut-off valve 3 provided at the intake three-way joint 12 and the control valve provided at the exhaust port 21 are both solenoid valves, which can only achieve remote control and meet the electrical control requirements, so as to adapt to the use requirements of intelligent adjustment.

[0033] More specifically, a connecting pipe 4 is provided between the interfaces of the intake three-way joints 12 of the main cabinet 1 and the sub-cabinets 2 and between the interfaces of the intake three-way joints 12 of the sub-cabinets 2 and the sub-cabinets 2. That is, when the adjacent intake three-way joints 12 are connected in series, the intake three-way joints 12 to be connected in series are connected by the connecting pipe 4 to realize the connection of the pipeline circuit. At this time, the connecting pipe 4 used for connection is a flexible pipe. Preferably, the flexible pipe is a corrugated pipe, which can not only meet the connection requirements, but also realize the adjustment of length and angle, and has good flexibility, thus facilitating the connection and installation between the main cabinet 1 and the sub-cabinets 2 and between the adjacent sub-cabinets 2, and the structural design is more reasonable.

[0034] In addition to exhausting air from the storage chamber of the auxiliary cabinet 2 through the exhaust port 21 as described above, the present embodiment also provides another way to exhaust the air from the storage chamber of the auxiliary cabinet 2. At this time, each auxiliary cabinet 2 is provided with an air outlet communicating with the storage chamber, so that the air in the storage chamber can be discharged through the air outlet. Moreover, a return air three-way joint is installed on each air outlet, and the air discharged from the corresponding air outlet is continuously discharged through the return air three-way joint. At the same time, the return air three-way joints of several auxiliary cabinets 2 are connected in series and then connected to the return air port of the constant temperature and humidity machine 11, realizing the connection between the storage chamber of each auxiliary cabinet 2 and the return air port of the constant temperature and humidity machine 11. Thus, when it is necessary to adjust the temperature and humidity of the auxiliary cabinet 2, the air extruded from the storage chamber can return to the return air port of the constant temperature and humidity machine 11 through the corresponding return air three-way joint, thereby realizing the internal circulation of the air and further avoiding the waste of resources. It should be noted that one of the interfaces of the return air three-way joint of the outermost auxiliary cabinet 2 is blocked by the cover 121, ensuring the airtightness of the air path. At the same time, a control valve is also provided at each return air three-way joint, that is, only when the air in the auxiliary cabinet 2 where gas exchange occurs and the temperature and humidity are adjusted is discharged through the corresponding return air three-way joint, the corresponding control valve will be opened, thus ensuring the sealing reliability and effectiveness of each auxiliary cabinet 2. Preferably, the structure of the cover 121 on the return air three-way joint is the same as that of the cover 121 on the intake air three-way joint 12, which is more convenient for processing. It should be noted that the exhaust port 21 and the air outlet on the auxiliary cabinet 2 are actually the same interface, and are only distinguished as external circulation and internal circulation for the exhaust methods respectively. The only difference between them lies in the subsequent connection methods with other structures, which will not be elaborated here.

[0035] More specifically, return air pipes are provided between the series-connected return air three-way joints and between the return air three-way joint and the return air port of the constant temperature and humidity machine 11. That is, adjacent return air three-way joints are connected in series through the return air pipe, and the series-connected return air three-way joints are connected to the return air port of the constant temperature and humidity machine 11 through the return air pipe, ensuring the sealing and smoothness of the internal circulation channel. In addition, the return air pipe is a flexible pipe with better flexibility, which can adapt to the adjustment of length and angle and meet the installation requirements in different situations.

[0036] More specifically, the intake air three-way joint 12 is arranged at the top of the main cabinet 1. Similarly, the intake air three-way joint 12 is also arranged at the top of the auxiliary cabinet 2, ensuring the smoothness of both sides of the main cabinet 1 and the auxiliary cabinet 2, avoiding the problem of space waste caused by the occupation of both sides of the main cabinet 1 or the auxiliary cabinet 2, and ensuring that several auxiliary cabinets 2 can be arranged along the side extension of the main cabinet 1, making the space utilization more reasonable. Preferably, the exhaust port 21 or the air outlet is located at the rear side of the lower part of the auxiliary cabinet 2, which is convenient for the air to enter from the top and then be discharged from the lower part, realizing the flow of the air in the storage chamber, and thus realizing the adjustment of the environment in the storage chamber.

[0037] More specifically, a protective cover 5 is also provided on the main cabinet 1 and the auxiliary cabinet 2. At this time, the intake tee joint 12 and the connecting pipe 4 are covered by the protective cover 5, that is, the protective cover 5 provides an external protection structure for the intake tee joint 12 and the connecting pipe 4, which not only improves the safety guarantee but also enhances the appearance aesthetics.

[0038] More specifically, the protective cover 5 is composed of several sections of cover bodies. At this time, the several sections of cover bodies include a middle cover body 51 and end cover bodies 52. During installation, the middle cover body 51 and the end cover bodies 52 are both provided with embedding grooves along their length directions to accommodate the intake tee joint 12 and the connecting pipe 4 through the embedding grooves. And, the embedding groove of the middle cover body 51 penetrates through both ends thereof, one end of the embedding groove of the end cover body 52 is a closed end, and the other end is a through end. And, the middle cover bodies 51 are connected end to end to form a strip structure. At the same time, the end cover bodies 52 are arranged at both ends of the overall structure formed by the middle cover bodies 51, realizing the extension of the end cover bodies 52 at both ends of the strip structure formed by the middle cover bodies 51 to cover the ends of the embedding grooves, effectively meeting the use requirements for the hidden installation of the intake tee joint 12 and the connecting pipe 4. And, the splicing of the number of the middle cover bodies 51 can adapt to the installation requirements of different numbers of auxiliary cabinets 2, and the structure has higher flexibility.

[0039] More specifically, the protective cover 5 further includes a bridging member 53. During installation, the bridging member 53 is arranged between two adjacent middle cover bodies 51 and between an adjacent middle cover body 51 and an end cover body 52. At this time, the bridging member 53 is arranged in the embedding groove, realizing the built-in installation of the bridging member 53. And, both ends of the bridging member 53 are respectively connected to two adjacent middle cover bodies 51 or an adjacent middle cover body 51 and an end cover body 52, realizing the connection between two adjacent sections of the protective cover 5, and the structural design is more reasonable.
