Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a fresh-keeping device and refrigeration equipment comprising the fresh-keeping device. Background Art

[0002] Vacuum preservation technology for refrigeration equipment creates a sealed vacuum environment, isolating food from the outside air to achieve antibacterial, moisture-proof, and antioxidant properties. The core principle is to extract air from the container and food using high pressure, creating a vacuum state that effectively inhibits the growth of aerobic bacteria and slows the oxidation process. In related technologies, due to the weak structure of vacuum barrels, the air inside the barrel is forced to the outside. This creates a pressure differential between the inside and outside of the barrel, causing deformation under the pressure, which can affect the seal of the vacuum barrel. Utility Model Content

DETAILED DESCRIPTION

[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] The present invention proposes a fresh-keeping device 100 and a refrigeration device including the fresh-keeping device 100. The fresh-keeping device 100 is provided with a plurality of first reinforcing ribs 20 to improve the structural strength of the fresh-keeping device 100, avoid deformation of the fresh-keeping device 100 under low pressure, and thus improve the sealing performance of the fresh-keeping device 100.

[0041] Reference Figures 1 to 9According to the fresh-keeping device 100 in the embodiment of the present invention, the fresh-keeping device 100 includes a barrel body 10, and the barrel body 10 constructs a low-pressure storage chamber with an opening 11. The barrel body 10 has a first end and a second end, and the opening 11 is set at the first end. The peripheral wall of the barrel body 10 is provided with a plurality of first reinforcing ribs 20, and the plurality of first reinforcing ribs 20 are distributed from the first end to the second end. In this way, the structural strength of the fresh-keeping device 100 can be improved, and deformation of the fresh-keeping device 100 under low pressure can be avoided, thereby improving the sealing performance of the fresh-keeping device 100.

[0042] Specifically, the preservation device 100 can be used on refrigeration equipment. The preservation device 100 generally adopts vacuum preservation technology. For example, by evacuating the inside of the barrel body 10 of the preservation device, the inside of the barrel body 10 is in a vacuum state, thereby realizing the preservation of the food inside the preservation device 100; but due to the pressure difference between the inside and the outside of the barrel body 10, the preservation device 100 will deform inward when subjected to pressure. At this time, a plurality of first reinforcing ribs 20 can be provided on the peripheral wall of the barrel body 10. The structural strength of the barrel body 10 is improved by the plurality of first reinforcing ribs 20. In this way, the deformation of the barrel body 10 caused by the internal and external pressure difference can be avoided.

[0043] Therefore, according to the fresh-keeping device 100 in the embodiment of the present invention, by providing multiple first reinforcing ribs 20, the structural strength of the fresh-keeping device 100 can be improved, and deformation of the fresh-keeping device 100 under low pressure can be avoided, thereby improving the sealing performance of the fresh-keeping device 100.

[0044] Furthermore, the density of the plurality of first reinforcing ribs 20 near the first end is greater than the density near the second end; wherein, the first end of the barrel body 10 is provided with an opening 11, and the opening 11 can facilitate the user to put food into the barrel body 10 and take food out of the barrel body 10; after the barrel body 10 is evacuated, the opening 11 of the barrel body 10 will also be deformed inwardly due to the pressure difference. At this time, the density of the plurality of first reinforcing ribs 20 near the first end can be greater than the density near the second end, so as to improve the structural strength of the barrel body 10 at the opening 11 and avoid the opening of the barrel body 10 The opening 11 is deformed inward due to the pressure difference, affecting the sealing performance of the fresh-keeping device 100; it can be understood that the barrel body 10 includes a first part close to the first end and a second part close to the second end, and the first part and the second part are both provided with a plurality of first reinforcing ribs 20, and the number of first reinforcing ribs 20 per unit area of ​​the first part is greater than the number of first reinforcing ribs 20 per unit area of ​​the second part, that is, the density of the multiple first reinforcing ribs 20 in the first part is greater than the density of the multiple first reinforcing ribs 20 in the second part, thereby improving the structural strength of the opening 11 of the barrel body 10.

[0045] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 9In some embodiments of the present invention, multiple first reinforcing ribs 20 are arranged at intervals along the direction from the first end to the second end, and the first reinforcing ribs 20 extend along the direction around the axis of the opening 11; in this way, the structural strength of the barrel body 10 and the opening 11 of the barrel body 10 can be improved, and the sealing performance of the preservation device 100 can be improved.

[0046] Of course, according to actual conditions, multiple first reinforcing ribs 20 can be arranged in a staggered manner to improve the structural strength of the barrel body 10.

[0047] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 9 In some embodiments of the present invention, the multiple first reinforcing ribs 20 include a first rib group 21 and a second rib group 22. The first rib group 21 is arranged near the first end, and the second rib group 22 is arranged near the second end. The spacing L1 between two adjacent first reinforcing ribs 20 in the first rib group 21 is smaller than the spacing L2 between two adjacent first reinforcing ribs 20 in the second rib group. In this way, the arrangement density of the multiple first reinforcing ribs 20 near the first end is greater than the arrangement density near the second end, thereby enhancing the structural strength of the opening of the barrel body 10 and improving the sealing performance of the preservation device 100.

[0048] In other embodiments of the present invention, the interval between two adjacent first reinforcing ribs 20 gradually decreases in the direction from the second end to the first end; it can be understood that the structure at the opening 11 of the barrel body 10 is relatively weak, and vacuuming will cause the edge of the opening 11 of the barrel body 10 to deform inward. Therefore, in the direction from the second end to the first end, the interval between two adjacent first reinforcing ribs 20 gradually decreases, so that the multiple first reinforcing ribs 20 are denser at the first end than at the second end, thereby improving the structural strength of the opening 11 of the barrel body 10, avoiding inward deformation of the opening 11, and improving the sealing performance of the preservation device 100.

[0049] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 9In some embodiments of the present invention, a plurality of second reinforcing ribs 30 are provided on the peripheral wall of the barrel body 10, and the plurality of second reinforcing ribs 30 are distributed along the direction around the axis of the opening 11, and the second reinforcing ribs 30 are staggered with the first reinforcing ribs 20; specifically, the fresh-keeping device 100 can preserve food through vacuum preservation technology, and the barrel body 10 of the fresh-keeping device 100 can be provided with a plurality of first reinforcing ribs 20 and a plurality of second reinforcing ribs 30, and the plurality of first reinforcing ribs 20 are distributed from the first end to the second end, and the plurality of second reinforcing ribs 30 are distributed along the direction around the axis of the opening 11, and the second reinforcing ribs 30 are staggered with the first reinforcing ribs 20. In this way, the structural strength of the fresh-keeping device 100 can be improved in multiple directions, and deformation of the fresh-keeping device 100 under low pressure can be avoided, thereby improving the sealing performance of the fresh-keeping device 100.

[0050] Furthermore, the barrel body 10 includes a first circumferential wall 121 and a second circumferential wall 122, and the density of the plurality of second reinforcing ribs 30 on the first circumferential wall 121 is greater than the density on the second circumferential wall 122. In this way, the structure of the barrel body 10 can be reinforced to prevent the barrel body 10 from deforming inward and affecting the sealing performance of the preservation device 100.

[0051] Reference Figures 1 to 9 In some embodiments of the present invention, the barrel body 10 includes a plurality of side panels 12, which are connected to form a low-pressure storage chamber. The side panels 12 include a first peripheral wall 121 and a second peripheral wall 122. The first peripheral wall 121 and the second peripheral wall 122 are distributed along the direction around the axis of the opening 11. In the normal projection of the side panel 12, the first peripheral wall 121 is far away from the connection of the side panel 12, and the second peripheral wall 122 is close to the connection of the side panel 12. In this way, the structural strength of the fresh-keeping device 100 can be improved, thereby improving the sealing performance of the fresh-keeping device 100.

[0052] Specifically, multiple side panels 12 are connected and enclose a low-pressure storage chamber. The structural strength of the connection between the multiple side panels 12 is relatively high, that is, the strength of the second peripheral wall 122 is relatively strong. In this way, when the side panels 12 of the barrel body 10 are subjected to pressure to deform inward, they have good pressure resistance; but the strength of the part of the side panel 12 away from the connection, that is, the first peripheral wall 121 is relatively weak, so that the opening 11 deforms inward after the barrel body 10 is vacuumed. Therefore, the arrangement density of the multiple second reinforcing ribs 30 on the first peripheral wall 121 can be greater than the arrangement density of the second peripheral wall 122, thereby enhancing the structural strength of the side panel 12 and avoiding sealing leakage caused by deformation of the side panel 12.

[0053] Reference Figures 1 to 9In other embodiments of the present invention, the barrel body 10 also includes a bottom plate 13, which is connected to multiple side plates 12 to close one side of the low-pressure storage chamber. The side plate 12 includes a first circumferential wall 121 and a second circumferential wall 122. The first circumferential wall 121 and the second circumferential wall 122 are distributed along the axial direction of the opening. In the normal projection of the side plate 12, the first circumferential wall 121 is close to the opening 11 and the second circumferential wall 122 is away from the opening 11. In this way, the structural strength of the opening 11 of the fresh-keeping device 100 can be improved, and the deformation of the opening 11 can be avoided to affect the sealing performance of the fresh-keeping device 100.

[0054] Reference Figures 1 to 9 In some embodiments of the present invention, the second reinforcing rib 30 extends along the axial direction of the opening 11, and multiple second reinforcing ribs 30 are arranged at intervals along the direction around the axis of the opening 11; in this way, the structural strength of the preservation device 100 can be improved, thereby improving the sealing performance of the preservation device 100.

[0055] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figures 6 to 9 In some embodiments of the present invention, the plurality of second reinforcing ribs 30 include a third rib group 31 and a fourth rib group 32, and the spacing L3 between two adjacent second reinforcing ribs 30 in the third rib group 31 is smaller than the spacing L4 between two adjacent second reinforcing ribs 30 in the fourth rib group 32. In this way, the arrangement density of the plurality of second reinforcing ribs 30 on the first peripheral wall 121 can be greater than the arrangement density on the second peripheral wall 122, thereby improving the structural strength of the preservation device 100 and improving the sealing performance of the preservation device 100.

[0056] Specifically, when the fresh-keeping device 100 is vacuumed, since the first circumferential wall 121 of the side panel 12 is lower in strength than the second circumferential wall 122 of the side panel 12, the first circumferential wall 121 of the side panel 12 will deform inward. Therefore, the distance L3 between the two adjacent second reinforcing ribs 30 in the third rib group 31 can be made smaller than the distance L4 between the two adjacent second reinforcing ribs 30 in the fourth rib group 32, so as to improve the structural strength of the first circumferential wall 121, thereby improving the structural strength of the side panel 12 and avoiding sealing leakage of the fresh-keeping device 100.

[0057] Reference Figure 4In some embodiments of the present invention, the multiple first reinforcing ribs 20 include a first rib group 21 and a second rib group 22. The first rib group 21 is arranged near the first end relative to the second rib group 22, and the second rib group 22 is arranged near the second end relative to the first rib group 21. Specifically, since the first rib group 21 is closer to the opening 11 of the barrel body 10, the distance L1 between two adjacent first reinforcing ribs 20 in the first rib group 21 can meet the following requirements: 20mm≤L1≤30mm. If L1 is less than 20mm, the multiple first reinforcing ribs 20 in the first rib group 21 are arranged more closely, resulting in a higher manufacturing cost of the fresh-keeping device 100. If L>30mm, the multiple first reinforcing ribs 20 in the first rib group 21 are arranged more loosely, resulting in insufficient structural strength of the fresh-keeping device 100 and easy deformation. Therefore, the distance L1 can be set within the range of 20mm to 30mm, wherein the distance L1 can be 20mm, 23mm, 25mm, 27mm, 30mm, etc.

[0058] In addition, since the second rib group 22 is farther away from the opening 11 of the barrel body 10, the spacing L2 between two adjacent first reinforcing ribs 20 in the second rib group 22 can satisfy: L2 ≥ 50 mm; if L2 < 50 mm, the multiple first reinforcing ribs 20 in the second rib group 22 are arranged more closely, resulting in a higher manufacturing cost of the fresh-keeping device 100; it can be understood that the second rib group 22 is farther away from the opening 11 of the barrel body 10 than the first rib group 21, so the multiple first reinforcing ribs 20 in the second rib group 22 can be arranged more loosely, which can achieve structural enhancement of the fresh-keeping device 100; wherein, the spacing L2 can be 50 mm, 55 mm, 60 mm, 70 mm, etc.

[0059] Reference Figure 4 In some embodiments of the present invention, in a direction perpendicular to the axis of the opening 11, the height dimension H1 of the first rib group 21 satisfies: 5mm≤H1≤10mm, which can take into account both the structural strength of the preservation device 100 and the manufacturing cost of the preservation device 100.

[0060] In detail, if H1 is less than 5 mm, the height of the multiple first reinforcing ribs 20 in the first rib group 21 is relatively low, resulting in a lower structural strength of the preservation device 100; if H1 is greater than 10 mm, the height of the multiple first reinforcing ribs 20 in the first rib group 21 is relatively high, resulting in a higher manufacturing cost of the preservation device 100. Therefore, in the normal direction corresponding to the side panel 12, the height dimension H1 of the first rib group 21 can be set within the range of 5 mm to 10 mm, wherein the height dimension H1 can be 5 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0061] Reference Figure 4In other embodiments of the present invention, in a direction perpendicular to the axis of the opening 11, the height dimension H2 of the second rib group 22 satisfies: 12mm≤H2≤18mm, which can take into account both the structural strength of the preservation device 100 and the manufacturing cost of the preservation device 100.

[0062] In detail, if H2 is less than 12 mm, the height of the multiple first reinforcing ribs 20 in the second rib group 22 is relatively low, resulting in a lower structural strength of the preservation device 100; if H2 is greater than 18 mm, the height of the multiple first reinforcing ribs 20 in the second rib group 22 is relatively high, resulting in a higher manufacturing cost of the preservation device 100. Therefore, in the normal direction corresponding to the side panel 12, the height dimension H2 of the second rib group 22 can be set within the range of 12 mm to 18 mm, wherein the height dimension H2 can be 12 mm, 14 mm, 16 mm, 18 mm, etc.

[0063] It can be understood that since the multiple first reinforcing ribs 20 of the first rib group 21 are denser than the multiple first reinforcing ribs 20 of the second rib group 22, the height dimension H1 of the first rib group 21 can be set lower than the height dimension H2 of the second rib group 22, so as to reduce the manufacturing cost of the preservation device 100 while taking into account the structural strength of the preservation device 100, and increase the space inside the barrel body 10 while keeping the height dimension of the barrel body 10 unchanged.

[0064] Reference Figure 7 In some embodiments of the present invention, the plurality of second reinforcing ribs 30 include a third rib group 31 and a fourth rib group 32. The third rib group 31 is arranged closer to the axis of the opening 11 relative to the fourth rib group 32, and the fourth rib group 32 is arranged farther away from the axis of the opening 11 relative to the third rib group 31. Specifically, since the third rib group 31 is closer to the axis of the opening 11, the spacing L3 between two adjacent second reinforcing ribs 30 in the third rib group 31 can satisfy the following conditions: 20 mm ≤ L3 ≤ 30 mm. If L3 is less than 20 mm, the plurality of second reinforcing ribs 30 in the third rib group 31 are arranged more closely, resulting in a higher manufacturing cost of the fresh-keeping device 100. If L3 is greater than 30 mm, the plurality of second reinforcing ribs 30 in the third rib group 31 are arranged more loosely, resulting in insufficient structural strength of the fresh-keeping device 100 and easy deformation. Therefore, the spacing L3 can be set within the range of 20 mm to 30 mm, wherein the spacing L3 can be 20 mm, 23 mm, 25 mm, 27 mm, 30 mm, etc.

[0065] In addition, since the fourth rib group 32 is further away from the axis of the opening 11, the spacing L4 between two adjacent second reinforcing ribs 30 in the fourth rib group 32 can satisfy: L4 ≥ 50 mm; if L4 < 50 mm, the multiple second reinforcing ribs 30 in the fourth rib group 32 are arranged more closely, resulting in a higher manufacturing cost of the preservation device 100; it can be understood that the fourth rib group 32 is farther away from the opening 11 of the barrel body 10 than the third rib group 31, so the multiple second reinforcing ribs 30 in the fourth rib group 32 can be arranged more loosely, which can achieve structural enhancement of the preservation device 100; wherein, the spacing L4 can be 50 mm, 55 mm, 60 mm, 70 mm, etc.

[0066] Reference Figure 4 In some embodiments of the present invention, the second reinforcing rib 30 includes a first rib portion 301 and a second rib portion 302 along the first end to the second end. In the direction perpendicular to the axis of the opening 11, the height dimension H3 of the first rib portion 301 satisfies: 5mm≤H3≤10mm, which can take into account the structural strength of the preservation device 100 and the manufacturing cost of the preservation device 100.

[0067] Specifically, if H3 is less than 5 mm, the height of the first rib 301 is relatively low, resulting in a lower structural strength of the fresh-keeping device 100. If H3 is greater than 10 mm, the height of the first rib 301 is relatively high, resulting in a higher manufacturing cost of the fresh-keeping device 100. Therefore, in the normal direction corresponding to the side panel 12, the height dimension H3 of the first rib 301 can be set within a range of 5 mm to 10 mm, wherein the height dimension H3 can be 5 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc. It should be noted that the direction from the first end to the second end can be along the axis of the opening 11 and away from the opening 11.

[0068] Reference Figure 4 In other embodiments of the present invention, in the normal direction corresponding to the side panel 12, the height dimension H4 of the second rib 302 satisfies: 12mm≤H4≤18mm, which can take into account the structural strength of the preservation device 100 and the manufacturing cost of the preservation device 100.

[0069] In detail, if H4 is less than 12 mm, the height of the second rib 302 is relatively low, resulting in a lower structural strength of the fresh-keeping device 100; if H4 is greater than 18 mm, the height of the second rib 302 is relatively high, resulting in a higher manufacturing cost of the fresh-keeping device 100. Therefore, in the normal direction corresponding to the side panel 12, the height dimension H4 of the second rib 302 can be set within the range of 12 mm to 18 mm, wherein the height dimension H4 can be 12 mm, 14 mm, 16 mm, 18 mm, etc.

[0070] It can be understood that since the first rib 301 is closer to the opening 11 of the barrel body 10 than the second rib 302, and the reinforcing ribs near the opening 11 of the barrel body 10 are relatively dense, the height dimension H3 of the first rib 301 can be set lower than the height dimension H4 of the second rib 302, so as to reduce the manufacturing cost of the fresh-keeping device 100 while taking into account the structural strength of the fresh-keeping device 100, and increase the internal space of the barrel body 10 while keeping the height dimension of the barrel body 10 unchanged.

[0071] Reference Figures 1 to 9 In some embodiments of the present invention, the fresh-keeping device 100 also includes a flange portion 40, which is connected to the edge of the opening 11 and extends in a direction away from the axis of the opening 11; specifically, the flange portion 40 has two opposite sides, one side of the flange portion 40 is connected to the edge of the opening 11 of the barrel body 10, and the other side extends in a direction away from the axis of the opening 11. In this way, the flange portion 40 can improve the structural strength of the opening 11 of the barrel body 10, and the flange portion 40 can withstand pressure when the barrel body 10 is vacuumed to ensure that the structure at the opening 11 of the barrel body 10 is not deformed, thereby improving the sealing performance of the fresh-keeping device 100.

[0072] Furthermore, the thickness dimension D1 of the flange portion 40 and the wall thickness D2 of the barrel body 10 can satisfy: 0.5mm≤(D1-D2)≤1mm. In this way, the structural strength at the opening 11 of the barrel body 10 can be further strengthened, the sealing performance of the fresh-keeping device 100 can be improved, and the manufacturing cost of the fresh-keeping device 100 can be reduced; if (D1-D2) is less than 0.5mm, the structural strength at the opening 11 of the barrel body 10 is low, and if (D1-D2) is greater than 1mm, the manufacturing cost of the fresh-keeping device 100 is high; wherein, (D1-D2) can be 0.5mm, 0.6mm, 0.8mm, 0.9mm, 1mm, etc.

[0073] Furthermore, the second reinforcing rib 30 extends along the axial direction of the opening 11, and the end of the second reinforcing rib 30 close to the opening 11 can be connected to the flange portion 40 to improve the structural strength of the opening 11 of the barrel body 10; and in the normal direction of the corresponding side panel 12, the height dimension of the end portion of the second reinforcing rib 30 connected to the flange portion 40 is not less than the height dimension of the remaining part of the second reinforcing rib 30 to improve the structural strength of the opening 11 of the barrel body 10.

[0074] In some embodiments of the present invention, the fresh-keeping device 100 also includes a plurality of second reinforcing ribs 30, which are arranged on the barrel body 10. The barrel body 10, the first reinforcing ribs 20, and the second reinforcing ribs 30 are integrally formed, which can further improve the overall structural strength of the fresh-keeping device 100 and prevent the fresh-keeping device 100 from being deformed when in a vacuum state.

[0075] Reference Figure 7 In some embodiments of the present invention, the side panel 12 includes a first peripheral wall 121 and a second peripheral wall 122, the second peripheral wall 122 is connected to the first peripheral wall 121, the first peripheral wall 121 is far away from the connection of the side panel 12, and the second peripheral wall 122 is close to the connection of the side panel 12, and the thickness dimension D3 of the first peripheral wall 121 and the thickness dimension D4 of the second peripheral wall 122 satisfy: 1mm≤(D3-D4); in this way, the structural strength of the part of the side panel 12 away from the connection can be improved, and the side panel 12 can be prevented from being deformed inward under pressure, thereby improving the structural strength of the fresh-keeping device 100.

[0076] In detail, the second circumferential wall 122 is the part of the side panel 12 close to the connection, and the first circumferential wall 121 is the part of the side panel 12 away from the connection. The connection is the connection where multiple side panels 12 are connected end to end. It can be understood that the second circumferential wall 122 has weaker structural strength because it is away from the connection of the side panel 12. When the barrel body 10 is vacuumed, the second circumferential wall 122 is easily deformed inward. Therefore, the structural strength of the second circumferential wall 122 can be improved by increasing the thickness of the second circumferential wall 122; wherein, the thickness dimension D3 of the first circumferential wall 121 and the thickness dimension D4 of the second circumferential wall 122 satisfy: 1mm≤(D3-D4), thereby improving the structural strength of the second circumferential wall 122; (D3-D4) can be 1mm, 2mm, 3mm, etc.

[0077] Reference Figures 1 to 9 In some embodiments of the present invention, the first reinforcing ribs 20 and the second reinforcing ribs 30 are both arranged on the outer surface of the barrel body 10, and the first reinforcing ribs 20 and the second reinforcing ribs 30 are arranged alternately, that is, the first reinforcing ribs 20 and the second reinforcing ribs 30 have an angle to improve the structural strength of the barrel body 10 in multiple directions, thereby improving the sealing performance of the preservation device 100.

[0078] Reference Figures 1 to 9 According to the refrigeration equipment in the embodiment of the present invention, the refrigeration equipment includes a box body and the fresh-keeping device 100 in the above embodiment. The fresh-keeping device 100 is arranged in the box body. By applying the aforementioned fresh-keeping device 100, the structural strength of the refrigeration equipment can be improved, and the sealing performance of the refrigeration equipment can be improved.

[0079] Specifically, the fresh-keeping device 100 can be used in refrigeration equipment. The interior of the fresh-keeping device 100 can be used to store food, and the food can be preserved by vacuuming. However, when the barrel body 10 is vacuumed, the barrel body 10 is easily deformed. Therefore, a plurality of first reinforcing ribs 20 can be provided on the barrel body 10 to improve the structural strength of the barrel body 10. Furthermore, since the opening 11 of the barrel body 10 is relatively weak, the density of the plurality of first reinforcing ribs 20 near the first end can be greater than the density of the plurality of first reinforcing ribs 20 near the second end, thereby improving the structural strength of the barrel body 10 at the opening 11, preventing the edge of the opening 11 from deforming inward, and improving the sealing performance of the fresh-keeping device 100. In addition, the barrel body 10 can also be provided with a plurality of second reinforcing ribs 30, which are staggered with the plurality of first reinforcing ribs 20 to further improve the structural strength of the barrel body 10.

[0080] Furthermore, multiple first reinforcing ribs 20 are arranged at intervals and extend in a direction around the axis of the opening 11, and multiple second reinforcing ribs 30 are arranged at intervals and extend in a direction around the axis of the opening 11, so as to increase the coverage of the multiple first reinforcing ribs 20 and the multiple second reinforcing ribs 30 on the barrel body 10, thereby improving the structural strength of the preservation device 100.

[0081] In addition, the spacing between two adjacent first reinforcing ribs 20 gradually decreases from the second end to the first end, thereby increasing the density of the multiple first reinforcing ribs 20 near the first end and preventing inward deformation of the edge of the opening 11 of the barrel body 10. Furthermore, in the normal projection of the side panel 12, the spacing between two adjacent second reinforcing ribs 30 gradually decreases in the direction near the axis of the opening 11, thereby increasing the structural strength of the portion of the side panel 12 away from the connection and preventing inward deformation of the side panel 12. Furthermore, multiple first reinforcing ribs 20 and multiple second reinforcing ribs 30 can be provided on the outer surface of the barrel body 10 to free up the internal space of the barrel body 10, thereby increasing the internal low-pressure storage chamber of the barrel body 10.

[0082] Furthermore, the plurality of first reinforcing ribs 20 include a first rib group 21 and a second rib group 22. The spacing L1 between two adjacent first reinforcing ribs 20 in the first rib group 21 satisfies the following conditions: 20 mm ≤ L1 ≤ 30 mm, ensuring a balanced balance between the structural strength and manufacturing cost of the fresh-keeping device 100. The spacing L2 between two adjacent first reinforcing ribs 20 in the second rib group 22 satisfies the following conditions: L2 ≥ 50 mm, thereby improving the structural strength and reducing the manufacturing cost of the fresh-keeping device 100. Furthermore, in the normal direction relative to the side panel 12, the height dimension H1 of the first rib group 21 satisfies the following conditions: 5 mm ≤ H1 ≤ 10 mm; and the height dimension H2 of the second rib group 22 satisfies the following conditions: 12 mm ≤ H2 ≤ 18 mm, ensuring a balanced balance between the structural strength and manufacturing cost of the fresh-keeping device 100.

[0083] Furthermore, the plurality of second reinforcing ribs 30 include a third rib group 31 and a fourth rib group 32. The spacing L3 between two adjacent second reinforcing ribs 30 in the third rib group 31 satisfies the following conditions: 20 mm ≤ L3 ≤ 30 mm, ensuring a balanced balance between the structural strength and manufacturing cost of the fresh-keeping device 100. The spacing L4 between two adjacent second reinforcing ribs 30 in the fourth rib group 32 satisfies the following conditions: L4 ≥ 50 mm, thereby improving the structural strength and reducing the manufacturing cost of the fresh-keeping device 100. Furthermore, the second reinforcing ribs 30 include a first rib portion 301 and a second rib portion 302 extending from the first end to the second end. The height dimension H3 of the first rib portion 301 satisfies the following conditions: 5 mm ≤ H3 ≤ 10 mm. The height dimension H4 of the second rib portion 302 satisfies the following conditions: 12 mm ≤ H4 ≤ 18 mm, ensuring a balanced balance between the structural strength and manufacturing cost of the fresh-keeping device 100.

[0084] Furthermore, the edge of the opening 11 of the barrel body 10 may be connected to a flange portion 40, extending in a direction away from the axis of the opening 11. When the edge of the opening 11 of the barrel body 10 is deformed toward the axis of the opening 11 under pressure, the flange portion 40 can have good pressure resistance, thereby preventing deformation of the edge of the opening 11 of the barrel body 10 and improving the sealing performance of the fresh-keeping device 100. In addition, the thickness dimension D1 of the flange portion 40 and the wall thickness D2 of the barrel body 10 meet the following relationship: 0.5mm≤(D1-D2)≤1mm, thereby improving the structural strength of the opening 11 of the barrel body 10 and reducing the manufacturing cost of the fresh-keeping device 100.

[0085] In addition, the side panel 12 includes a first circumferential wall 121 and a second circumferential wall 122. The second circumferential wall 122 is used to connect multiple side panels 12 end to end. The second circumferential wall 122 is close to the connection between the side panels 12, and the first circumferential wall 121 is far away from the connection between the side panels 12. Therefore, it is necessary to increase the thickness of the first circumferential wall 121 to improve the structural strength of the first circumferential wall 121. Therefore, the thickness dimension D3 of the first circumferential wall 121 and the thickness dimension D4 of the second circumferential wall 122 can satisfy: 1mm≤(D3-D4) to improve the structural strength of the first circumferential wall 121.

[0087] In some specific examples of the present invention, a layout and design structure of the reinforcing ribs of a vacuum barrel (i.e., barrel body 10) are proposed; by arranging reinforcing ribs with different spacings and heights on the outer wall of the vacuum barrel according to different stress deformation positions, the lightweight is achieved as much as possible while meeting the strength requirements; at the same time, a vacuum barrel body structure with locally reinforced wall thickness is proposed.
