[0058] Figure 1 This is a schematic diagram of the structure of a refrigeration device according to some embodiments of the present invention.

[0059] like Figure 1 As shown, the refrigeration equipment provided in this embodiment of the present invention may include a housing 1. The housing 1 may have a hollow cuboid structure. It is understood that in other embodiments, the housing 1 may also have a hollow shell structure of other shapes.

[0060] In some embodiments, a refrigeration compartment (not shown in the figure) may be formed inside the housing 1. The refrigeration compartment can serve as an independent storage space, such as a refrigerator, a variable temperature compartment, or a freezer, to meet different storage needs such as refrigeration and freezing depending on the type of stored items.

[0061] In some embodiments, multiple refrigeration chambers may be provided inside the housing 1. The multiple refrigeration chambers may be arranged vertically or horizontally within the housing 1.

[0062] like Figure 1 As shown, in some embodiments, the housing 1 may contain a liner (not shown in the figure). A refrigeration compartment may be formed within the liner. Multiple liners may be installed within the housing 1. These multiple liners may be arranged vertically or horizontally within the housing 1. Each liner may form one or more refrigeration compartments.

[0063] In some embodiments, a foam layer (not shown in the figure) may be provided inside the housing 1. The foam layer may be formed in the space between the outer wall of the housing liner and the inner wall of the housing 1. This foam layer can be used to insulate the interior of the housing liner and the refrigeration compartment, thereby achieving the insulation performance of the refrigeration equipment.

[0064] like Figure 1 As shown, in some embodiments, a refrigeration system (not shown) may be installed inside the housing 1. The refrigeration system may be located inside the housing 1. The refrigeration system can be used to provide cold air to the interior of the refrigeration equipment to maintain a low-temperature environment in each refrigeration compartment.

[0065] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor can act as the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0066] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser can be used to receive refrigerant flowing from the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thus lowering the temperature of the refrigerant.

[0067] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0068] In some embodiments, the refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator. The compressor, condenser, throttling device, and evaporator may be connected in sequence to form a refrigeration circuit. The refrigerant may circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0069] Figure 2 yes Figure 1 Schematic diagram of the middle box door 2.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, a door 2 may be provided on the front side of the housing 1. The door 2 can be used to open and close the refrigeration compartment. The door 2 and the housing 1 can be connected by a hinge, so that the door 2 of the refrigeration equipment can rotate around the axis of the hinge, thereby opening and closing the door 2 of the refrigeration equipment, and thus opening or closing the corresponding refrigeration compartment.

[0071] In some embodiments, multiple doors 2 can be provided. Multiple doors 2 can be configured one-to-one with multiple refrigeration compartments. It should be noted that in other embodiments, multiple doors 2 can also be opened and closed simultaneously in a single refrigeration compartment.

[0072] like Figure 2 As shown, in some embodiments, the door 2 may include a door housing 21. The front sidewall of the door housing 21 may form a door panel. The door panel may serve as the front exterior surface of the door 2.

[0073] In some embodiments, the door 2 may include a door insert 22. The door insert 22 may be disposed on the back side of the door shell 21. A foam layer may be formed between the door insert 22 and the door shell 21. Filling the foam layer with foam material can achieve the heat insulation and thermal insulation performance of the door 2.

[0074] like Figure 2 As shown, in some embodiments, the refrigeration equipment may include a door shelf 23. The door shelf 23 may be provided on the side wall of the cabinet door 2 facing the refrigeration compartment. In this way, items can be placed on the cabinet door 2 by means of the door shelf 23, thereby making full use of the space in the refrigeration compartment and on the cabinet door 2.

[0075] In some embodiments, multiple door shelves 23 may be provided, and the multiple door shelves 23 may be arranged vertically at intervals. It should be noted that the number of door shelves 23 and the spacing between adjacent door shelves 23 can be adjusted as needed, and are not limited here.

[0076] In some embodiments, a door liner 22 may be provided with a rib 221 protruding from it. The rib 221 may be arranged vertically. Two ribs 221 may be provided. The two ribs 221 are arranged at a left-right interval. The door shelf 23 may be disposed between the two vertically arranged ribs 221. In this way, the door shelf 23 can be fixed to the door liner 22 by the ribs 221, thereby stably fixing the door shelf 23 to the side wall of the door 2.

[0077] In some embodiments, the door shelf 23 may be detachably mounted on the door 2. The door shelf 23 may also be detachably mounted on the rib 221 of the door liner 22.

[0078] It should be noted that in some other embodiments, the door shelf 23 can also be integrally formed in the door insert 22, thereby allowing the door shelf 23 to be integrally formed on the side wall of the door 2.

[0079] like Figure 2 As shown, in some embodiments, the refrigeration device may include a vacuum preservation container 3. The vacuum preservation container 3 may be mounted on the door 2. The vacuum preservation container 3 may be supported on the door shelf 23. A storage cavity may be formed inside the vacuum preservation container 3. The interior of the vacuum preservation container 3 may be evacuated, thereby creating a vacuum storage environment inside the storage cavity. Thus, the vacuum preservation container 3 can be used for low-temperature vacuum preservation and storage of food.

[0080] Figure 3 yes Figure 2 The diagram shows the structure of the door 2 in another state.

[0081] like Figure 2 and Figure 3As shown, in some embodiments, the refrigeration device may include a vacuum assembly. The vacuum assembly can be used to create a vacuum inside the vacuum food storage container 3, thereby forming a vacuum storage environment inside the container 3.

[0082] In some embodiments, the vacuuming assembly may include a vacuum pump (not shown). The vacuum pump may be located inside the door 2. The vacuum pump may be connected to the storage cavity inside the vacuum food storage container 3. In this way, the vacuum pump can be used to evacuate the storage cavity inside the vacuum food storage container 3, thereby creating a vacuum storage environment inside the storage cavity of the vacuum food storage container 3.

[0083] In some embodiments, the vacuum assembly may include a vacuum connector 4. The suction end of a vacuum pump may be connected to the vacuum connector 4. The vacuum connector 4 may be used to connect with the storage cavity inside the vacuum food storage container 3. In this way, the vacuum pump can use the vacuum connector 4 to evacuate the storage cavity inside the vacuum food storage container 3, thereby creating a vacuum storage environment inside the storage cavity of the vacuum food storage container 3.

[0084] In some embodiments, the vacuum assembly may include a vacuum line (not shown in the figure). The vacuum line may be located between the vacuum pump and the vacuum connector 4. One end of the vacuum line may be connected to the vacuum pump. The other end of the vacuum line may be connected to the vacuum connector 4. In this way, the pumping end of the vacuum pump can be connected to the vacuum connector 4 through the vacuum line, thereby allowing the vacuum pump to evacuate the interior of the vacuum food storage container 3 sequentially through the vacuum line and the vacuum connector 4.

[0085] like Figure 2 and Figure 3 As shown, in some embodiments, the vacuum connector 4 is rotatably mounted on the door 2. When the vacuum connector 4 is rotatably mounted, it can either align with or detach from the interior of the vacuum preservation container 3 on the door 2. When the vacuum connector 4 is rotatably mounted and detached from the vacuum preservation container 3, the vacuum preservation container 3 can be removed from the door 2. When the vacuum connector 4 is rotatably mounted and aligned with the interior of the vacuum preservation container 3, it can evacuate the storage cavity inside the vacuum preservation container 3, creating a vacuum preservation environment within the storage cavity. Thus, the rotatable design of the vacuum connector 4 facilitates the user's evacuation of the vacuum preservation container 3 on the door 2 without affecting the removal and placement of the vacuum preservation container 3.

[0086] In some embodiments, the vacuum connector 4 is rotatably disposed above the door shelf 23. When the vacuum food storage container 3 is disposed on the door shelf 23, the vacuum connector 4 can be rotatably disposed downwards and contact the top surface of the vacuum food storage container 3, allowing the vacuum pump to sequentially evacuate the interior of the vacuum food storage container 3 through the vacuum pipeline and the vacuum connector 4. When the vacuum connector 4 can be rotatably disposed upwards, the vacuum connector 4 can be separated from the top surface of the vacuum food storage container 3, allowing the vacuum food storage container 3 to be removed from the door shelf 23.

[0087] It should be noted that in some other embodiments, the vacuum connector 4 can also be movably mounted on the door. The vacuum connector 4 can also be moved to the vacuum preservation container 3 and dock with its interior, allowing the vacuum pump to sequentially evacuate the interior of the vacuum preservation container 3 through the vacuum pipeline and the vacuum connector 4.

[0088] Furthermore, in some other embodiments, the vacuum assembly may not include the vacuum connector 4. The vacuum pump may also be directly connected to the interior of the vacuum food storage container 3 via a vacuum tubing.

[0089] Figure 4 yes Figure 3 The diagram shows the structure of the vacuum food storage box 3.

[0090] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration device may include multiple vacuum food storage containers 3. These multiple vacuum food storage containers 3 can be stacked sequentially on top of the door shelf 23. The multiple vacuum food storage containers 3 can be used to categorize and store food. Stacking multiple vacuum food storage containers 3 on top of the door shelf 23 fully utilizes the space above the door 2 and the door shelf 23.

[0091] like Figure 3 As shown, in some embodiments, when the vacuum connector 4 is flipped downwards, it can contact the top surface of the uppermost vacuum storage container 3 among the multiple vacuum storage containers 3 on the door shelf 23, thereby evacuating the interior of the uppermost vacuum storage container 3. When the vacuum connector 4 is flipped upwards, it can separate from the top surface of the uppermost vacuum storage container 3, thereby allowing the multiple vacuum storage containers 3 stacked on the door shelf 23 to be picked up and put in sequence.

[0092] like Figure 3 and Figure 4As shown, in some embodiments, the plurality of vacuum food storage containers 3 stacked above the door shelf 23 may include at least two vacuum food storage containers 3, namely a first vacuum food storage container 31 and a second vacuum food storage container 32. In this way, the two vacuum food storage containers 3 can be used to store food in categories. The first vacuum food storage container 31 and the second vacuum food storage container 32 are stacked above the door shelf 23, which can make full use of the space above the door 2 and the door shelf 23.

[0093] In some embodiments, the second vacuum food storage container 32 can be detachably supported on the door shelf 23. The first vacuum food storage container 31 can be detachably stacked on the second vacuum food storage container 32. In this case, when the vacuum connector 4 is flipped, the vacuum connector 4 can contact or separate from the top surface of the first vacuum food storage container 31 above the second vacuum food storage container 32. Thus, when it is necessary to vacuum the second vacuum food storage container 32, the vacuum connector 4 can be flipped downwards so that the vacuum connector 4 can contact the top surface of the first vacuum food storage container 31, thereby vacuuming the inside of the first vacuum food storage container 31. When it is necessary to remove or place the first vacuum food storage container 31 and the second vacuum food storage container 32, the vacuum connector 4 can be flipped upwards so that the vacuum connector 4 can separate from the top surface of the first vacuum food storage container 31, thereby allowing the first vacuum food storage container 31 and the second vacuum food storage container 32 stacked on the door shelf 23 to be removed or placed sequentially.

[0094] In some embodiments, the first vacuum food storage container 31 can be detachably supported on the door shelf 23. The second vacuum food storage container 32 can be detachably stacked on the first vacuum food storage container 31. In this case, when the vacuum connector 4 is flipped, the vacuum connector 4 can contact or separate from the top surface of the second vacuum food storage container 32 above the first vacuum food storage container 31. Thus, when it is necessary to vacuum the second vacuum food storage container 32, the vacuum connector 4 can be flipped downwards so that the vacuum connector 4 can contact the top surface of the second vacuum food storage container 32, thereby vacuuming the inside of the second vacuum food storage container 32. When it is necessary to remove or place the first vacuum food storage container 31 and the second vacuum food storage container 32, the vacuum connector 4 can be flipped upwards so that the vacuum connector 4 can separate from the top surface of the second vacuum food storage container 32, thereby allowing the first vacuum food storage container 31 and the second vacuum food storage container 32 stacked on the door shelf 23 to be removed or placed sequentially. In this way, users can flexibly stack and use the first vacuum food storage box 31 and the second vacuum food storage box 32 on the stacking door shelf 23, and vacuum the first vacuum food storage box 31 and the second vacuum food storage box 32 respectively.

[0095] It should be noted that in some other embodiments, the number of vacuum food storage boxes 3 stacked on the door shelf 23 can be adjusted as needed, and no limitation is made here.

[0096] Figure 5 yes Figure 4A schematic diagram of its decomposed structure.

[0097] like Figure 5 As shown, in some embodiments, the top surface of the first vacuum food storage container 31 may be provided with a first vacuum port 3121. The top surface of the second vacuum food storage container 32 may be provided with a second vacuum port 3221.

[0098] When the second vacuum food storage container 32 is supported on the door shelf 23 and the first vacuum food storage container 31 is stacked on top of the second vacuum food storage container 32, the vacuum connector 4 can be connected to or disconnected from the first vacuum port 3121 on the top surface of the first vacuum food storage container 31 when it is flipped. In this way, the vacuum pump can evacuate the inside of the first vacuum food storage container 31 through the vacuum connector 4 and the first vacuum port 3121.

[0099] When the first vacuum food storage container 31 is supported on the door shelf 23 and the second vacuum food storage container 32 is stacked on top of the first vacuum food storage container 31, the vacuum connector 4 can be connected to or disconnected from the second vacuum port 3221 on the top surface of the second vacuum food storage container 32 when it is flipped. In this way, the vacuum pump can evacuate the inside of the second vacuum food storage container 32 through the vacuum connector 4 and the second vacuum port 3221.

[0100] It should be noted that in some other embodiments, the first vacuum port 3121 may not be located on the top surface of the first vacuum food storage container 31. The first vacuum port 3121 may also be located on other side walls of the first vacuum food storage container 31.

[0101] In some other embodiments, the second vacuum port 3221 may not be located on the top surface of the second vacuum food storage container 32. The second vacuum port 3221 may also be located on other side walls of the second vacuum food storage container 32.

[0102] Figure 6 yes Figure 5 A structural diagram from another perspective.

[0103] like Figure 5 and Figure 6 As shown, in some embodiments, the bottom of the first vacuum food storage container 31 may be provided with a first positioning rib 3111. The top surface of the second vacuum food storage container 32 may be provided with a second positioning groove 3222. The first positioning rib 3111 can be adapted to the second positioning groove 3222.

[0104] When the first vacuum food storage container 31 is stacked on top of the second vacuum food storage container 32, the first positioning rib 3111 can be supported at the second positioning groove 3222. In this way, the first positioning rib 3111 and the second positioning groove 3222 can be positioned and engaged to stably stack the first vacuum food storage container 31 on top of the second vacuum food storage container 32, thereby improving the stacking stability of the first vacuum food storage container 31 and the second vacuum food storage container 32.

[0105] like Figure 5 and Figure 6 As shown, in some embodiments, a first positioning groove 3122 may be recessed on the top surface of the first vacuum food storage container 31. A second positioning rib 3211 may be protruding from the bottom of the second vacuum food storage container 32. The second positioning rib 3211 may be adapted to the first positioning groove 3122.

[0106] When the second vacuum food storage container 32 is stacked on top of the first vacuum food storage container 31, the second positioning rib 3211 can be supported at the first positioning groove 3122. In this way, the second vacuum food storage container 32 can be stably stacked on top of the first vacuum food storage container 31 through the positioning cooperation between the second positioning rib 3211 and the first positioning groove 3122, thereby improving the stacking stability of the first vacuum food storage container 31 and the second vacuum food storage container 32.

[0107] like Figure 5 As shown, in some embodiments, the first positioning groove 3122 may be annular. The first positioning groove 3122 may be arranged circumferentially around the top surface of the first vacuum food storage container 31 near the edge.

[0108] In some embodiments, the second positioning groove 3222 may be annular. The second positioning groove 3222 may be arranged circumferentially around the top surface of the second vacuum food storage container 32 near the edge.

[0109] like Figure 6 As shown, in some embodiments, the first positioning rib 3111 is annular. The first positioning rib 3111 can be arranged circumferentially around the periphery of the bottom edge of the first vacuum food storage container 31.

[0110] In some embodiments, the second positioning rib 3211 is annular. The second positioning rib 3211 may be arranged circumferentially around the periphery of the bottom edge of the second vacuum food storage container 32.

[0111] like Figure 5 and Figure 6As shown, in some embodiments, when the first vacuum food storage container 31 is stacked on the second vacuum food storage container 32, the annular first positioning rib 3111 can cooperate with the annular second positioning groove 3222 to position and support the first vacuum food storage container 31 on the peripheral area of ​​the top of the second vacuum food storage container 32. This allows the force on the first vacuum food storage container 31 to be evenly distributed on the top surface of the second vacuum food storage container 32 and the force to be transferred to the peripheral wall of the second vacuum food storage container 32. This reduces the deformation of the top surface of the second vacuum food storage container 32 and improves the support strength of the top surface of the second vacuum food storage container 32.

[0112] In some embodiments, when the second vacuum food storage container 32 is stacked on the first vacuum food storage container 31, the annular second positioning rib 3211 can cooperate with the annular first positioning groove 3122 to position and support the second vacuum food storage container 32 on the peripheral area of ​​the top of the first vacuum food storage container 31. This allows the force on the second vacuum food storage container 32 to be evenly distributed on the top surface of the first vacuum food storage container 31 and the force to be transmitted to the peripheral wall of the first vacuum food storage container 31. This reduces the deformation of the top surface of the first vacuum food storage container 31 and improves the support strength of the top surface of the first vacuum food storage container 31.

[0113] Figure 7 yes Figure 5 A cross-sectional view of the first vacuum food storage container 31. Figure 8 yes Figure 7 A partially enlarged structural diagram.

[0114] like Figure 7 and Figure 8 As shown, in some embodiments, the first vacuum food storage container 31 may include a first container body 311 and a first lid 312. The first container body 311 has a top opening. A first storage cavity 3110 may be formed inside the first container body 311. The first lid 312 may be detachably placed over the top opening of the first container body 311, thereby allowing the first storage cavity 3110 to be opened or closed via the first lid 312.

[0115] In some embodiments, the first positioning groove 3122 may be recessed into the top surface of the first lid 312. The first positioning groove 3122 may be annular and arranged circumferentially around the top surface of the first lid 312 near its edge. Thus, when the second vacuum food storage container 32 is stacked on top of the first vacuum food storage container 31, the weight of the second vacuum food storage container 32 can be transferred through the annular first positioning groove 3122 to the peripheral edge of the first lid 312, and then to the peripheral wall of the first container body 311.

[0116] In some embodiments, the first positioning rib 3111 may protrude from the bottom of the first container body 311. The first positioning rib 3111 may be annular and arranged circumferentially around the periphery of the bottom edge of the first container body 311. Thus, when the first vacuum food storage container 31 is stacked on the second vacuum food storage container 32, the weight of the first vacuum food storage container 31 can be transferred to the periphery of the top of the first vacuum food storage container 31 through the annular first positioning rib 3111.

[0117] Figure 9 yes Figure 5 A cross-sectional view of the second vacuum food storage container 32. Figure 10 yes Figure 9 A partially enlarged structural diagram.

[0118] like Figure 9 and Figure 10 As shown, in some embodiments, the second vacuum food storage container 32 may include a second container body 321 and a second lid 322. The second container body 321 has a top opening. A second storage cavity 3210 may be formed inside the second container body 321. The second lid 322 may be detachably placed over the top opening of the second container body 321, thereby allowing the second storage cavity 3210 to be opened or closed via the second lid 322.

[0119] In some embodiments, the second positioning groove 3222 may be recessed into the top surface of the second lid 322. The second positioning groove 3222 may be annular and arranged circumferentially around the top surface of the second lid 322 near its edge. Thus, when the first vacuum food storage container 31 is stacked on the second vacuum food storage container 32, the weight of the first vacuum food storage container 31 can be transferred to the peripheral area of ​​the second lid 322 through the cooperation of the annular first positioning rib 3111 and the second positioning groove 3222, and then to the peripheral wall of the second container body 321.

[0120] In some embodiments, the second positioning rib 3211 may protrude from the bottom of the second box body 321. The second positioning rib 3211 may be annular and arranged circumferentially around the periphery of the bottom edge of the second box body 321. Thus, when the second vacuum food storage box 32 is stacked on the first vacuum food storage box 31, the weight of the second vacuum food storage box 32 can be transferred to the periphery of the first box lid 312 through the cooperation of the annular second positioning rib 3211 and the first positioning groove 3122, and then to the periphery of the first box body 311.

[0121] Figure 11 yes Figure 3 The layout is shown in a cross-sectional view. Figure 12 yes Figure 11 A partially enlarged structural diagram.

[0122] like Figure 8 , Figure 11 and Figure 12 As shown, in some embodiments, the first vacuum port 3121 can be located on the top surface of the first lid 312. When the first vacuum food storage container 31 is stacked on the second vacuum food storage container 32, the vacuum connector 4 can be flipped to align with the first vacuum port 3121 on the top surface of the first lid 312, allowing the vacuum pump to evacuate the interior of the first vacuum food storage container 31 through the vacuum connector 4 and the first vacuum port 3121.

[0123] like Figure 8 As shown, in some embodiments, the first vacuum food storage container 31 may include a first vacuum valve 313. The first vacuum valve 313 may be disposed at the first vacuum port 3121. The first vacuum valve 313 may be used to seal the first vacuum port 3121, thereby sealing the first storage cavity 3110 inside the first vacuum food storage container 31.

[0124] In some embodiments, the first vacuum valve 313 may include a first cylindrical portion 3131. The first cylindrical portion 3131 may pass through the first vacuum port 3121. The outer diameter of the first cylindrical portion 3131 may be smaller than the inner diameter of the first vacuum port 3121, so that a first ventilation gap (not shown in the figure) is formed between the outer wall of the first cylindrical portion 3131 and the inner wall of the first vacuum port 3121. When the vacuum connector 4 evacuates the first vacuum port 3121, the first cylindrical portion 3131 may be moved upward by force, and the air inside the first vacuum food storage container 31 may be extracted through the first ventilation gap, thereby creating a vacuum environment inside the first vacuum food storage container 31.

[0125] like Figure 8 As shown, in some embodiments, the first vacuum valve 313 may include a first sealing portion 3132. The first sealing portion 3132 may be disposed on the periphery of the top of the first column portion 3131. The first column portion 3131 is annular and circumferentially arranged around the periphery of the top of the first column portion 3131. A first sealing surface 3123 may be formed on the top surface of the first lid 312. The first sealing surface 3123 may be arranged around the periphery of the top opening of the first vacuum port 3121. The first sealing portion 3132 may be disposed above the first sealing surface 3123. The first sealing portion 3132 may be used to abut against the first sealing surface 3123 to seal the first vacuum port 3121, thereby sealing the first storage cavity 3110 inside the first vacuum preservation box 31.

[0126] like Figure 12As shown, when the vacuum connector 4 evacuates the first vacuum port 3121, the first sealing part 3132 can be moved upward under force, so that a second ventilation gap (not shown in the figure) can be formed between the bottom surface of the first sealing part 3132 and the first sealing surface 3123. This allows the second ventilation gap to connect with the first ventilation gap, thereby allowing the first storage cavity 3110 inside the first vacuum food storage container 31 to connect with the vacuum connector 4 through the first ventilation gap and the second ventilation gap. At this time, the vacuum pump can extract the air inside the first vacuum food storage container 31 through the vacuum connector 4, thereby achieving vacuuming inside the first vacuum food storage container 31.

[0127] After the vacuuming of the first vacuum food storage box 31 is completed, a negative pressure can be formed inside the first vacuum food storage box 31. Under the action of the internal and external pressure difference, the first sealing part 3132 can be tightly attached to the first sealing surface 3123, thereby sealing the first vacuum port 3121 and the first storage cavity 3110 inside the first vacuum food storage box 31.

[0128] It should be noted that in some embodiments, when it is necessary to open the first vacuum food storage box 31, the first sealing part 3132 can be moved upward by external force, so that a second ventilation gap can be formed between the bottom surface of the first sealing part 3132 and the first sealing surface 3123. The air outside the first vacuum food storage box 31 can flow into the first storage cavity 3110 inside the first vacuum food storage box 31 through the second ventilation gap and the first ventilation gap, thereby depressurizing the first vacuum food storage box 31 and making the first lid 312 easy to open.

[0129] like Figure 8 As shown, in some embodiments, the first vacuum valve 313 may include a first abutment portion 3133. The first abutment portion 3133 is disposed on the periphery of the bottom of the first column portion 3131. The first abutment portion 3133 is used to abut against the bottom opening of the first vacuum port 3121. When the first vacuum port 3121 is evacuated or depressurized, the first vacuum valve 313 can be moved upward by force, so that the first abutment portion 3133 abuts against the periphery of the bottom opening of the first vacuum port 3121, thereby preventing the first vacuum valve 313 from dislodging from the first vacuum port 3121.

[0130] In some embodiments, the first abutment portion 3133 may be annular. The first abutment portion 3133 may be arranged circumferentially around the outer peripheral wall of the bottom of the first column portion 3131.

[0131] Figure 13 yes Figure 11 Cross-sectional views of some other embodiments. Figure 14 yes Figure 13 A partially enlarged structural diagram.

[0132] like Figure 10 , Figure 13 and Figure 14 As shown, in some embodiments, the second vacuum port 3221 is located on the top surface of the second lid 322. When the second vacuum food storage box 32 is stacked on the first vacuum food storage box 31, the vacuum connector 4 can be flipped to align with the second vacuum port 3221 on the top surface of the second lid 322, allowing the vacuum pump to evacuate the interior of the second vacuum food storage box 32 through the vacuum connector 4 and the second vacuum port 3221.

[0133] like Figure 10 As shown, in some embodiments, the second vacuum food storage container 32 may include a second vacuum valve 323. The second vacuum valve 323 may be disposed at the second vacuum port 3221. The second vacuum valve 323 may be used to seal the second vacuum port 3221, thereby sealing the first storage cavity 3110 inside the second vacuum food storage container 32.

[0134] In some embodiments, the second vacuum valve 323 may include a second cylindrical portion 3231. The second cylindrical portion 3231 may pass through the second vacuum port 3221. The outer diameter of the second cylindrical portion 3231 may be smaller than the inner diameter of the second vacuum port 3221, so that a third ventilation gap (not shown in the figure) is formed between the outer wall of the second cylindrical portion 3231 and the inner wall of the second vacuum port 3221. When the vacuum connector 4 evacuates the second vacuum port 3221, the second cylindrical portion 3231 may be moved upward under force, and the air inside the second vacuum food storage container 32 may be extracted through the third ventilation gap, thereby creating a vacuum environment inside the second vacuum food storage container 32.

[0135] like Figure 10 As shown, in some embodiments, the second vacuum valve 323 may include a second sealing portion 3232. The second sealing portion 3232 may be disposed on the periphery of the top of the second column portion 3231. The second column portion 3231 is annular and circumferentially arranged around the periphery of the top of the second column portion 3231. A second sealing surface 3223 may be formed on the top surface of the second lid 322. The second sealing surface 3223 may be arranged around the periphery of the top opening of the second vacuum port 3221. The second sealing portion 3232 may be disposed above the second sealing surface 3223. The second sealing portion 3232 may be used to abut against the second sealing surface 3223 to seal the second vacuum port 3221, thereby sealing the second storage cavity 3210 inside the second vacuum preservation box 32.

[0136] like Figure 14As shown, when the vacuum connector 4 evacuates the second vacuum port 3221, the second sealing part 3232 can move upward under force, forming a fourth ventilation gap (not shown in the figure) between the bottom surface of the second sealing part 3232 and the second sealing surface 3223. This fourth ventilation gap connects with the third ventilation gap, allowing the second storage cavity 3210 inside the second vacuum food storage container 32 to connect with the vacuum connector 4 through the third and fourth ventilation gaps. At this time, the vacuum pump can extract air from inside the second vacuum food storage container 32 through the vacuum connector 4, achieving vacuuming inside the second vacuum food storage container 32.

[0137] After the vacuuming of the second vacuum food storage box 32 is completed, a negative pressure can be formed inside the second vacuum food storage box 32. Under the action of the internal and external pressure difference, the second sealing part 3232 can be tightly attached to the second sealing surface 3223, thereby sealing the second vacuum port 3221, and then sealing the second storage cavity 3210 inside the second vacuum food storage box 32.

[0138] It should be noted that in some embodiments, when it is necessary to open the second vacuum food storage box 32, the second sealing part 3232 can be moved upward by external force, so that a fourth ventilation gap can be formed between the bottom surface of the second sealing part 3232 and the second sealing surface 3223. The air outside the second vacuum food storage box 32 can flow into the second storage cavity 3210 inside the second vacuum food storage box 32 through the fourth ventilation gap and the third ventilation gap, thereby depressurizing the second vacuum food storage box 32 and making the second lid 322 easy to open.

[0139] like Figure 10 As shown, in some embodiments, the second vacuum valve 323 may include a second abutment portion 3233. The second abutment portion 3233 is disposed on the periphery of the bottom of the second column portion 3231. The second abutment portion 3233 is used to abut against the bottom opening of the second vacuum port 3221. When the second vacuum port 3221 is evacuated or depressurized, the second vacuum valve 323 can be moved upward by force, so that the second abutment portion 3233 abuts against the periphery of the bottom opening of the second vacuum port 3221, thereby preventing the second vacuum valve 323 from dislodging from the second vacuum port 3221.

[0140] In some embodiments, the second abutment portion 3233 may be annular. The second abutment portion 3233 may be circumferentially arranged around the outer peripheral wall of the bottom of the second column portion 3231.

[0141] like Figure 8 and Figure 12 As shown, in some embodiments, a first positioning ring 3124 may be protruding from the top surface of the first cover 312. The first positioning ring 3124 may be arranged around the periphery of the first vacuum port 3121.

[0142] When the vacuum connector 4 is flipped so that it aligns with the top of the first vacuum food storage container 31, the vacuum connector 4 can seal against the first positioning ring 3124, isolating the inside of the first positioning ring 3124 from its outside. This allows the vacuum connector 4 to align with the first vacuum port 3121 inside the first positioning ring 3124. Thus, when the vacuum pump draws a vacuum, air inside the first vacuum food storage container 31 can flow into the vacuum connector 4 through the first vacuum port 3121 and be extracted by the vacuum pump, achieving vacuuming inside the first vacuum food storage container 31.

[0143] like Figure 10 and Figure 14 As shown, in some embodiments, a second positioning ring 3224 may be protruding from the top surface of the second cover 322. The second positioning ring 3224 may be arranged around the periphery of the second vacuum port 3221.

[0144] When the vacuum connector 4 is flipped so that it aligns with the top of the second vacuum food storage container 32, the vacuum connector 4 can seal against the second positioning ring 3224, isolating the inside of the second positioning ring 3224 from its outside. This allows the vacuum connector 4 to align with the second vacuum port 3221 inside the second positioning ring 3224. Thus, when the vacuum pump draws a vacuum, air inside the second vacuum food storage container 32 can flow into the vacuum connector 4 through the second vacuum port 3221 and be extracted by the vacuum pump, achieving vacuuming inside the second vacuum food storage container 32.

[0145] like Figure 11 and Figure 12 As shown, in some embodiments, a sealing ring 41 may be provided on the vacuum connector 4. The sealing ring 41 may be made of a flexible material. The sealing ring 41 may be annular. When the vacuum connector 4 is aligned with the top of the first vacuum food storage container 31, the sealing ring 41 can seal against the first positioning ring 3124, thereby ensuring the sealing performance of the connection between the vacuum connector 4 and the first vacuum port 3121, so that the air inside the first vacuum food storage container 31 can be smoothly extracted.

[0146] like Figure 13 and Figure 14 As shown, in some embodiments, when the vacuum connector 4 is aligned with the top of the second vacuum food storage container 32, the sealing ring 41 can seal against the second positioning ring 3224, thereby ensuring the sealing of the connection between the vacuum connector 4 and the second vacuum port 3221, so that the air inside the second vacuum food storage container 32 can be smoothly extracted.

[0147] like Figure 7 and Figure 12As shown, in some embodiments, the bottom of the first housing 311 may be recessed with a first receiving groove 3112. The first positioning rib 3111 may be arranged around the periphery of the first receiving groove 3112.

[0148] When the first vacuum food storage container 31 is stacked on top of the second vacuum food storage container 32, the first receiving groove 3112 can be located above the top surface of the second lid 322. At this time, the second positioning ring 3224 on the top surface of the second lid 322 can be accommodated in the first receiving groove 3112. In this way, the first receiving groove 3112 can avoid the second positioning ring 3224 on the top surface of the second lid 322, so that the first vacuum food storage container 31 can be stacked more stably on the second vacuum food storage container 32.

[0149] In some embodiments, when the first vacuum food storage container 31 is stacked on the second vacuum food storage container 32, the top of the second positioning ring 3224 can abut against the top wall of the first receiving groove 3112. At this time, the height of the second positioning ring 3224 can be the same as the depth of the first receiving groove 3112. This allows the bottom of the first vacuum food storage container 31 to be supported on the second positioning ring 3224, thereby enabling the first vacuum food storage container 31 to be stacked more stably on the second vacuum food storage container 32.

[0150] like Figure 9 and Figure 14 As shown, in some embodiments, the bottom of the second housing 321 may be recessed with a second receiving groove 3212. The second positioning rib 3211 may be arranged around the periphery of the second receiving groove 3212.

[0151] When the second vacuum food storage container 32 is stacked on top of the first vacuum food storage container 31, the second receiving groove 3212 can be located above the top surface of the first lid 312. At this time, the first positioning ring 3124 on the top surface of the first lid 312 can be accommodated in the second receiving groove 3212. In this way, the second receiving groove 3212 can avoid the first positioning ring 3124 on the top surface of the first lid 312, so that the second vacuum food storage container 32 can be stacked more stably on the first vacuum food storage container 31.

[0152] In some embodiments, when the second vacuum food storage container 32 is stacked on top of the first vacuum food storage container 31, the top of the first positioning ring 3124 can abut against the top wall of the second receiving groove 3212. At this time, the height of the first positioning ring 3124 can be the same as the depth of the second receiving groove 3212. This allows the bottom of the second vacuum food storage container 32 to be supported on the first positioning ring 3124, thereby enabling the second vacuum food storage container 32 to be stacked more stably on the first vacuum food storage container 31.

[0153] like Figure 7 , Figure 8 and Figure 12As shown, in some embodiments, the first vacuum food storage container 31 may include a first sealing ring 314. The first sealing ring 314 may be disposed between the first lid 312 and the first container body 311 to seal the gap between the first lid 312 and the first container body 311, thereby achieving a seal for the first vacuum food storage container 31.

[0154] In some embodiments, the first sealing ring 314 may be annular. The first sealing ring 314 may be disposed on the peripheral edge of the bottom surface of the first lid 312. When the first lid 312 is closed over the top opening of the first box body 311, the first sealing ring 314 may be supported on the top area of ​​the peripheral sidewall of the first box body 311, so that the first sealing ring 314 may be sandwiched between the peripheral edge of the bottom surface of the first lid 312 and the top of the peripheral sidewall of the first box body 311, thereby sealing the gap between the first lid 312 and the first box body 311, and achieving the sealing of the first vacuum food storage box 31.

[0155] like Figure 7 and Figure 12 As shown, in some embodiments, a first reinforcing rib 3125 may be provided on the bottom surface of the first lid 312. Multiple first reinforcing ribs 3125 may be provided. Multiple first reinforcing ribs 3125 can increase the structural strength of the first lid 312.

[0156] like Figure 9 , Figure 10 and Figure 14 As shown, in some embodiments, the second vacuum food storage container 32 may include a second sealing ring 324. The second sealing ring 324 may be disposed between the second lid 322 and the second body 321 to seal the gap between the second lid 322 and the second body 321, thereby achieving a seal on the second vacuum food storage container 32.

[0157] In some embodiments, the second sealing ring 324 may be annular. The second sealing ring 324 may be disposed on the peripheral edge of the bottom surface of the second lid 322. When the second lid 322 is closed over the top opening of the second box body 321, the second sealing ring 324 may be supported on the top area of ​​the peripheral sidewall of the second box body 321, so that the second sealing ring 324 may be sandwiched between the peripheral edge of the bottom surface of the second lid 322 and the top of the peripheral sidewall of the second box body 321, thereby sealing the gap between the second lid 322 and the second box body 321, and achieving the sealing of the second vacuum food storage box 32.

[0158] like Figure 9 and Figure 14 As shown, in some embodiments, a second reinforcing rib 3225 may be provided on the bottom surface of the second cover 322. Multiple second reinforcing ribs 3225 may be provided. Multiple second reinforcing ribs 3225 can increase the structural strength of the second cover 322.

[0159] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
