As another example, at least one of a, b, or c can be represented as: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple.

[0022] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific accompanying drawings and embodiments.

[0023] like Figure 11 As shown, this application embodiment first provides a storage device 200, which includes a device body 9 and an exhaust assembly 100 disposed on the device body 9. The device body 9 includes a cavity wall 91 and an airtight bag 92. The airtight bag 92 is a flexible, compressible bag, and its internal sealed cavity 920 is connected to the exhaust assembly 100. The exhaust assembly 100 is fixedly disposed on one of the cavity walls 91. Through the exhaust assembly 100, gas inside the sealed cavity 920 can be discharged, achieving exhaust compression of the airtight bag 92.

[0024] Multiple cavity walls 91 are interconnected and enclosed, defining a space for storing the airtight bag 92. Specifically, the cavity walls 91 can be in the form of fully enclosing the airtight bag 92 or in the form of partially enclosing the airtight bag 92.

[0025] The form of the storage device 200 and its cavity wall 91 is not limited. For example, the storage device 200 can be a suitcase, see [reference needed]. Figure 11 As shown, the cavity wall 91 includes the various compartment walls of the suitcase. Alternatively, in other alternative embodiments, the storage device 200 can be a portable storage structure such as a handbag or backpack. In more embodiments, the storage device 200 can also be a storage box, etc.

[0026] Specifically, an opening (not shown) is provided on the cavity wall 91, a part of the exhaust assembly 100 is located inside the cavity wall 91 and outside the sealed cavity 920, and another part is confined outside the cavity wall 91. By fixing these two parts together, the exhaust assembly 100 can be kept fixed on the cavity wall 91.

[0027] like Figure 11 As shown, an exhaust pipe 93 is connected between the exhaust assembly 100 and the airtight bag 92. The exhaust pipe 93 can be a flexible pipe, such as a flexible plastic pipe. The flexible exhaust pipe 93 can adapt to the shape changes of the airtight bag 92 during the exhaust process, avoiding the interaction of tension between the airtight bag 92 and the exhaust assembly 100, which would affect the airtightness at various points along the exhaust path.

[0028] In some embodiments, the cavity wall 91 in the storage device 200 may be omitted, and the airtight bag 92 may be entirely exposed. In some embodiments, the airtight bag 92 may be detachably connected to the exhaust assembly 100. When it is necessary to vacuum the airtight bag 92, the exhaust assembly 100 is connected to the airtight bag 92. When the vacuuming of the airtight bag 92 is completed or when it is not necessary, the exhaust assembly 100 is detached from the airtight bag 92.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the exhaust assembly 100 provided in this embodiment includes a housing 20, an exhaust pump 30, a circuit board assembly 40, and a positioning module 60, wherein, as Figure 4 and Figure 5 As shown, the housing 20 has a first space 220, and the exhaust pump 30 is disposed in the first space 220; the circuit board assembly 40 includes a circuit board 41, which is disposed in the housing 20 and connected to the exhaust pump 30, and a positioning module 60 is disposed in the first space 220, which is disposed on the circuit board 41 and connected to the circuit board 41.

[0030] Circuit board 41 is used to control the start and stop of the exhaust pump 30. Positioning module 60 is integrated on circuit board 41.

[0031] The storage device 200 and its exhaust assembly 100 provided in this application embodiment have a positioning module 60 disposed on and connected to the circuit board 41, so that the exhaust assembly 100 also integrates the positioning function. On the storage device 200, there is no need to reserve space, installation structure and circuit for the positioning module 60 separately, which can integrate the functions and simplify the structure of the storage device 200.

[0032] The type of positioning module 60 is not limited; any module capable of positioning can be used. In some embodiments, the positioning module 60 may be a satellite positioning module, including any one or more of GPS, BeiDou, GLONASS, and Galileo modules. It may also be a combination of the satellite positioning module 60 and other auxiliary positioning technologies, such as satellite positioning + inertial navigation (IMU), satellite positioning + WiFi + Bluetooth, satellite positioning + cellular network (LBS), etc. In other embodiments, the positioning module 60 may be a multi-source fusion positioning module including Bluetooth and ultra-wideband (UWB) technologies.

[0033] In some embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, the exhaust assembly 100 also includes a battery assembly 50, which is disposed on the side of the circuit board 41 facing the inner bottom wall of the housing 20. The battery assembly 50 is electrically connected to the circuit board 41. The battery assembly 50 supplies power to the circuit board 41, which in turn supplies power to the exhaust pump 30 and the positioning module 60.

[0034] Battery assembly 50 may include a battery pack (not shown), which includes one or more individual batteries. Depending on the voltage and capacity provided by each individual battery, and the voltage required for the operation of the exhaust pump 30 and positioning module 60, the batteries in the battery pack can be combined in different ways. For example, the battery pack may include multiple batteries connected in series, or connected in parallel, or packaged together in a series-parallel combination.

[0035] In some embodiments of this application, the battery assembly 50 further includes a fuse (not shown), which is connected between the positive output terminal of the battery pack and the circuit board 41, or between the positive output terminal of the battery pack and the circuit board 41. The fuse is made of a low-temperature alloy. When the battery pack experiences a short circuit or excessive output current, the fuse can melt to cut off the current path between the battery assembly 50 and the circuit board 41, preventing localized overheating or even fire within the exhaust assembly 100. In particular, flammable items such as clothing may be stored in the airtight bag 92 within the storage device 200; the fuse helps ensure the safety of the exhaust assembly 100 and the storage device 200.

[0036] Within the first space 220, the exhaust pump 30 and the battery assembly 50 are arranged side by side, rather than stacked in a direction perpendicular to the circuit board 41, as shown below. Figure 5 and Figure 7 As shown. This makes the dimensions of the housing 20 as close as possible in different directions, without the housing 20 having a large depth, which is beneficial to the manufacturing of the housing 20.

[0037] Battery assembly 50 may include a primary battery or a secondary battery. In some embodiments of this application, battery assembly 50 includes a secondary battery, and, as... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the circuit board assembly 40 also includes a charging interface 42, which is located on the side of the circuit board 41 opposite to the exhaust pump 30. The user can charge the battery assembly 50 via the charging interface 42. Furthermore, the side of the circuit board 41 with the charging interface 42 is the side accessible to the user; in this case, the battery assembly 50 and the exhaust pump 30 are at least partially hidden on the other side of the circuit board 41.

[0038] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the positioning module 60 is located on the side of the circuit board 41 opposite to the battery assembly 50 and the exhaust pump 30. The advantage is that there is enough safe space on the side of the circuit board 41 opposite to the battery assembly 50 and the exhaust pump 30 to install the positioning module 60, avoiding physical interference between the positioning module 60 and the battery assembly 50, the exhaust pump 30, etc.

[0039] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the circuit board assembly 40 also includes an indicator light 44, which is located on the side of the circuit board 41 opposite to the exhaust pump 30. The indicator light 44 is electrically connected to the circuit board 41. The indicator light 44 is used to indicate at least one operating state of the circuit board 41. For example, when the circuit board 41 is charging, the indicator light 44 can light up to provide a first indication; when the exhaust pump 30 is operating, the indicator light 44 can light up to provide a second indication; and when the battery assembly 50 has insufficient power, the indicator light 44 can light up to provide a third indication, etc.

[0040] The advantages are: first, there is enough safe space on the side of the circuit board 41 away from the battery assembly 50 and the exhaust pump 30 to set up the indicator light 44; second, the indicator light 44 is not hidden on the other side of the circuit board 41, and the user can easily observe the indicator light 44.

[0041] In some embodiments, such as Figure 4 and Figure 5 As shown, the circuit board assembly 40 also includes an electrical connector 45, which is located on the side of the circuit board 41 opposite to the exhaust pump 30 and is connected to the circuit board 41 and the battery assembly 50. Similarly, there is sufficient safety space on the side of the circuit board 41 opposite to the battery assembly 50 and the exhaust pump 30 to accommodate the electrical connector 45.

[0042] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the circuit board assembly 40 also includes a control switch 43, which is located on the side of the circuit board 41 away from the exhaust pump 30 and is used to connect or disconnect the exhaust pump 30 and the circuit board 41 to control the start and stop of the exhaust pump 30.

[0043] In some embodiments of this application, such as Figure 5 and Figure 7 As shown, the exhaust pump 30 includes a motor 31 and a fan 32. The motor 31 is electrically connected to the circuit board 41, and the fan 32 is connected to the output shaft of the motor 31. The circuit board 41 provides the motor 31 with the electrical energy required for its operation. The output shaft of the motor 31 drives the fan 32 to rotate, thereby realizing the flow of air. Specifically, when the fan 32 rotates, it can create a negative pressure on the side near the exhaust pipe 93, thereby allowing the air in the airtight bag 92 to be discharged.

[0044] like Figure 4 , Figure 5As shown in Figure 7, the housing 20 includes an outer shell 21 and an inner shell 22 disposed within the outer shell 21. The exhaust assembly 100 may further include a first cover 23 connected to the edge of the outer shell 21 and / or the edge of the inner shell 22. A first space 220 is formed on the inner shell 22. The first cover 23 can be used to substantially close the first space 220. When the exhaust assembly 100 is installed on the cavity wall 91, the housing 20 is located within the aforementioned opening, and the first cover 23 is located outside the cavity wall 91, while the outer shell 21 and the inner shell 22 are located inside the cavity wall 91. The edge of the outer shell 21 and the edge of the first cover 23 clamp the cavity wall 91. Thus, the outer shell 21 and the first cover 23 are fixed to the cavity wall 91, and the inner shell 22 is stably located inside the outer shell 21.

[0045] In some embodiments of this application, the outer shell 21 is used to house the inner shell 22 and to connect with the first cover 23; the outer shell 21 is also used to connect to the exhaust pipe 93 via the connecting pipe 80. The inner shell 22 is used to house and secure the aforementioned battery assembly 50, exhaust pump 30, and circuit board assembly 40, etc.

[0046] like Figure 4 and Figure 5 As shown, in some embodiments of this application, a first connecting portion 225 protrudes from the bottom wall of the inner shell 22, and the first connecting portion 225 is used to connect with the circuit board 41. Specifically, the circuit board 41 can be fixedly connected to the first connecting portion 225 by a first locking member (not shown, such as a screw).

[0047] like Figure 5 and Figure 6 As shown, in some embodiments of this application, a second connecting portion 211 protrudes from the inner bottom wall of the outer shell 21, and a fourth through hole 227 is provided on the inner shell 22. The second connecting portion 211 passes through the fourth through hole 227 and is connected to the first cover 23 via a second locking member 81. The purpose of this arrangement is twofold: firstly, it eliminates the need for a second connecting portion 211 on the inner shell 22, simplifying its structure and manufacturing; secondly, the outer shell 21 is directly connected to the first cover 23 via the second connecting portion 211. The end of the second connecting portion 211 facing the first cover 23 can be very close to, or even abut, the first cover 23, thus maintaining a stable connection. Simultaneously, the second connecting portion 211 is also relatively close to the edge of the cover, reducing the degree of deformation of the edge of the first cover 23, allowing the first cover 23 and the outer shell 21 to stably clamp the cavity wall 91. Figure 5 and Figure 7 As shown, a sealing ring 26 is provided between the edge of the first cover 23 and the edge of the outer shell 21.

[0048] like Figure 4 and Figure 5As shown, the first cover 23 is located on the side of the circuit board 41 away from the exhaust pump 30. The first cover 23 is configured to expose a part of the structure on the circuit board 41 and hide the other parts.

[0049] like Figure 4 and Figure 5 As shown, in some embodiments, the first cover 23 is provided with a first through hole 231, a second through hole 232, and a third through hole 233. The first through hole 231 is provided for the control switch 43 so that the control switch 43 can be exposed and operated by the user. The second through hole 232 is provided for the charging interface 42 so that the charging interface 42 can be exposed and connected to an external power source by the user. The third through hole 233 is provided for the indicator light 44 so that the indicator light 44 can be exposed and the user can observe the status of the exhaust assembly 100.

[0050] like Figure 5 and Figure 6 As shown, the inner shell 22 includes a first inner shell 221 and a second inner shell 222. The first space 220 includes a first subspace 2210 and a second subspace 2220. The first subspace 2210 is located on the first inner shell 221, and the second subspace 2220 is located outside the first inner shell 221 and between the second inner shell 222. The motor 31 is located in the first subspace 2210, and the fan 32 is located in the second subspace 2220. The purpose of this arrangement is that the inner shell 22 is manufactured separately from the first inner shell 221 and the second inner shell 222 and assembled together. On the one hand, the motor 31 can be installed separately in the first subspace 2210, and the fan 32 can be installed separately on the outside of the first inner shell 221 and then connected to the exhaust pump 30, which can simplify the installation of the exhaust pump 30 in the first space 220. On the other hand, the motor 31 and the fan 32 have their own installation space, which can be installed more stably. For example, the outside of the first inner shell 221 and the side of the second inner shell 222 facing the first inner shell 221 provide a larger installation surface.

[0051] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, an air outlet 226 is provided on the side of the first inner housing 221 near the second inner housing 222 and / or on the second inner housing 222, and the air outlet 226 communicates with the second subspace 2220. When the fan 32 rotates, air from the exhaust pipe 93 is discharged from the air outlet 226.

[0052] In a direction perpendicular to the output shaft of motor 31 and parallel to circuit board 41, air outlet 226 is offset from the output shaft of motor 31. In other words, in the direction perpendicular to circuit board 41, air outlet 226 is not directly opposite the rotation center of fan 32. The purpose of this arrangement is that fan 32 discharges air tangentially, so for the offset air outlet 226, the discharged air can pass through the outlet 226 generally in a straight line, rather than at an angle. This, in turn, reduces the exhaust noise of exhaust pump 30.

[0053] like Figures 2 to 5 as well as Figure 7 As shown, in some embodiments, the exhaust assembly 100 further includes a second cover 24, which is movably disposed on the first cover 23 and is used to expose at least the first through hole 231, the second through hole 232, and the third through hole 233 of the first cover 23. That is, when the user needs to operate the exhaust assembly 100, the second cover 24 can be in a second position, exposing the first through hole 231, the second through hole 232, and the third through hole 233; when the user does not need to operate the exhaust assembly 100, the second cover 24 can be in a first position to cover the first through hole 231, the second through hole 232, and the third through hole 233.

[0054] The second cover 24 is located on the side of the first cover 23 away from the housing 20. The second cover 24 is movable relative to the first cover 23 so that at least the control switch 43, the charging interface 42, the indicator light 44, etc. are exposed.

[0055] The second cover 24 can move in various ways relative to the first cover 23.

[0056] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the second cover 24 is slidable relative to the first cover 23. Specifically, as... Figure 9 and Figure 10 As shown, the first cover 23 has a groove 236, and the second cover 24 has a protruding structure (not shown) on the side surface facing the first cover 23. The protruding structure can slide within the groove 236 in a direction parallel to the circuit board 41, thereby allowing the second cover 24 to cover at least a portion of the first cover 23 (as shown in Figure 8) and expose that portion (such as...). Figure 9 (As shown). Alternatively, conversely, the groove 236 can be provided on the side surface of the second cover 24 facing the first cover 23, and the protruding structure can also be provided on the first cover 23.

[0057] like Figure 9 and Figure 10As shown, the first cover 23 is also provided with a receiving groove 230, and a sliding groove 236 is provided on the inner wall of the receiving groove 230, such as the bottom wall. The second cover 24 can be located within the receiving groove 230 and can slide at least partially out of the receiving groove 230. The advantage is that the second cover 24 does not protrude from the first cover 23, but can remain flush with the first cover 23.

[0058] like Figure 9 and Figure 10 As shown, in some embodiments of this application, the exhaust assembly 100 further includes an elastic abutment 70. The elastic abutment 70 is disposed on the first cover 23 and faces the second cover 24, or disposed on the first inner housing 221 and passing through the first cover 23 before facing the second cover 24. The elastic abutment 70 is used to abut against the side surface of the second cover 24 facing the first cover 23. By utilizing the elastic potential energy of the elastic abutment 70, a certain force can be applied to the second cover 24, making it less likely for the second cover 24 to slide relative to the first cover 23. Instead, it will only slide within the sliding groove 236 and the receiving groove 230 when the user applies a certain pushing force to the second cover 24. The advantage is that when the exhaust assembly 100 does not need to be operated, the second cover 24 can be kept in a basically stable position without easily sliding.

[0059] like Figure 10 As shown, in some embodiments of this application, the first cover 23 is further provided with a fifth through hole 234, a portion of the elastic abutment 70 is located in the fifth through hole 234, and another portion protrudes from the first cover 23 and is used to abut against the second cover 24. The advantage of this arrangement is that the elastic abutment 70 can have a larger height, which facilitates processing and manufacturing, and can provide sufficient elastic potential energy to act on the second cover 24.

[0060] The form of the elastic abutment 70 is not limited, as long as it can be compressed in a direction perpendicular to the circuit board 41. In some embodiments, the elastic abutment 70 may be elastic in its entirety, for example, it may be an elastic column in its entirety. In other embodiments, the portion of the elastic abutment 70 located in the fifth through hole 234 (the first portion) is a rigid member, and the portion of the elastic abutment 70 that abuts against the second cover 24 (the second portion) may extend or retract relative to the first portion.

[0061] In some embodiments, the end of the resilient abutment 70 that abuts against the second cover 24 has an arc-shaped guide surface. For example, the end of the resilient abutment 70 that abuts against the second cover 24 is spherical, quasi-spherical, or the like. Specifically, the second part of the resilient abutment 70 includes a spherical abutment joint, which is connected to the first part by a spring or the like.

[0062] In some embodiments, the second cover 24 can change its position relative to the first cover 23 by rotating or flipping it, such as... Figure 1 and Figure 2 As shown.

[0063] like Figure 2 and Figure 7 As shown, the second cover 24 has a third connecting part 241 on the side facing the first cover 23. Figure 2 In the diagram, the third connecting part 241 is shown in dashed lines. The third connecting part 241 is connected to the first cover 23, but the connection is not fixed. The second cover 24 rotates approximately around the position where the third connecting part 241 is connected to the first cover 23.

[0064] Specifically, such as Figure 3 and Figure 4 As shown, the first cover 23 is also provided with a sixth through hole 235, the third connecting part 241 passes through the sixth through hole 235 and is located in the first space 220, and, as Figure 7 As shown, a limiting boss 242 is provided on the portion of the third connecting part 241 located within the first space 220. The third connecting part 241 can be held within the sixth through hole 235 and rotated within the sixth through hole 235 so that the second cover 24 can rotate relative to the first cover 23.

[0065] The third connecting portion 241 is used to connect the second cover 24 to the first cover 23. The third connecting portion 241 can be a rigid component or a flexible component. In some embodiments, the third connecting portion 241 can be a component with a certain deformability, for example, a flexible columnar structure. Therefore, the limiting boss 242 of the third connecting portion 241 can pass through the sixth through hole 235 after deformation, and the limiting boss 242 can have a large size after recovery and is not easily detached from the sixth through hole 235.

[0066] To ensure that the first cover 23 can rotate and is not easily deformed, the first cover 23 can be a rigid component, such as a rigid plastic part. The third connecting part 241 and the first cover 23 can be an integrally molded structure, such as a two-color injection molded integral structure.

[0067] like Figure 4 , Figure 5 and Figure 7As shown, in some embodiments of this application, the exhaust assembly 100 further includes a limiting ring 25, which is disposed on the third connecting portion 241 and located between the limiting boss 242 and the first cover 23. The limiting ring 25 occupies the space between the limiting boss 242 and the first cover 23. The limiting boss 242 can abut against the limiting ring 25, and the limiting ring 25 can abut against the first cover 23. The advantage is that, to facilitate the passage of the third connecting portion 241 and its limiting boss 242 through the sixth through hole 235, the third connecting portion 241 is typically long. After the limiting boss 242 passes through the sixth through hole 235, due to the action of the limiting ring 25, the limiting boss 242 allows the second cover 24 to remain close to the first cover 23. That is, while allowing the second cover 24 to rotate, the second cover 24 can also remain close to the first cover 23. The limiting ring 25 may be a ring with a notch so that it can be engaged with the third connecting portion 241 from the radial side of the third connecting portion 241.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
