DETAILED DESCRIPTION

[0034] 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.

[0035] Combine Figures 1 to 6 According to an embodiment of the present invention, the fresh-keeping container 1000 includes a barrel body 100, a panel 200, and a sealing member 20. The barrel body 100 has a storage cavity 101 with a front opening, which can provide a storage space for the fresh-keeping container 1000. A sealing boss 10 is provided on the front of the barrel body 100, and the sealing boss 10 surrounds the opening. The panel 200 is configured to open and close the opening. The sealing member 20 is provided on the panel 200 and abuts against the sealing boss 10 when the panel 200 closes the opening, forming a sealed structure around the opening. In other words, the fresh-keeping container 1000 has a barrel body 100 that can be opened and closed. The user can store food in the storage space of the barrel body 100 through the opening, and then close the storage space with the panel 200 to isolate the food that needs to be kept fresh from the outside world. Furthermore, in order to improve the preservation effect, a sealing boss 10 is provided on the side of the barrel body 100 facing the panel 200, and the panel 200 is provided with a sealing member 20. When the user closes the opening, the panel 200 seals the front of the barrel body 100. As a result, the sealing member 20 of the panel 200 abuts and cooperates with the sealing boss 10 in front of the barrel body 100, forming a sealing structure at the opening, thereby further improving the sealing effect. In addition, by providing a sealing structure on the fresh-keeping container 1000, the stability of the panel 200 after closing the opening of the barrel body 100 can be improved. In the closed state, the panel 200 is tightly matched with the barrel body 100, making it difficult for the panel 200 to separate from the barrel body 100, which is conducive to improving the structural stability and improving the reliability of the fresh-keeping container 1000 when in use.

[0036] According to the fresh-keeping container 1000 of the embodiment of the present invention, by arranging a sealing boss 10 in front of the barrel body 100 and arranging a sealing member 20 on the panel 200 suitable for forming a sealing structure with the sealing boss 10, the sealing and structural stability of the panel 200 after closing the opening of the barrel body 100 can be improved, which is beneficial to improving the fresh-keeping effect and reliability of the fresh-keeping container 1000.

[0037] In actual application, the user can open and close the barrel body 100 through the control panel 200, so that the user can put in or take out food. After closing, an enclosed space is formed between the barrel body 100 and the panel 200, and the environment inside the fresh-keeping container 1000 is more stable, which is conducive to improving the fresh-keeping effect.

[0038] Further, combined with Figure 5 In some embodiments of the present invention, the sealing boss 10 is configured as an annular strip extending around the opening. This can be positioned around the opening, avoiding gaps and improving the sealing effect. Furthermore, the strip-shaped sealing boss 10 can be laid along the front edge of the barrel 100, flexibly adapting to gaps of various sizes and shapes, thereby improving sealing performance and providing strong adaptability and ease of application. Furthermore, the annular structure improves the structural stability of the sealing boss 10 and reduces the risk of creating sanitary blind spots, making it easier to clean and maintain.

[0039] Combine Figure 5 In some embodiments of the present invention, the shape of the sealing boss 10 is the same as the shape of the peripheral wall of the barrel body 100, which can improve the sealing effect and overall aesthetics.

[0040] In some embodiments of the present invention, the sealing boss 10 is configured as a square strip with arc transitions at the corners, which can improve the flexibility of the corners and facilitate cleaning of the corners. The square strip shape can improve compactness and has a certain structural strength.

[0041] Combine Figure 5 In some embodiments of the present invention, the sealing bosses 10 include at least two spaced apart from each other from the inside to the outside. When the panel 200 is closed, at least two sealing bosses 10 abut against the sealing member 20. Thus, the sealing bosses 10 can form an inner and outer two-layer sealing structure on the outer periphery of the opening in front of the barrel body 100, which is conducive to improving the sealing effect. In addition, when one of the sealing bosses fails to seal, the other sealing boss can still play a sealing role. Specifically, in combination with Figure 5The sealing boss 10 may include a first sealing boss 11 located on the inner side and a second sealing boss 12 located on the outer side of the first sealing boss 11, forming a double-layer seal from the inside to the outside. There is no gap between the first sealing boss 11 and the second sealing boss 12, that is, the first sealing boss 11 and the second sealing boss 12 are connected. Alternatively, there may be a gap between the first sealing boss 11 and the second sealing boss 12.

[0042] More specifically, in some embodiments of the present invention, in the projection along the front-to-back direction, the gaps between the inner edge of the sealing boss 10 and the periphery of the opening are substantially the same. In this way, the sealing boss 10 can separate the periphery of the opening from the outer periphery of the front of the barrel body 100 through the sealing boss 10, and the gaps between the sealing boss 10 and the periphery of the opening are the same, which can improve the stability and aesthetics of the structure. In particular, when the seal 20 cooperates with the sealing boss 10, the sealing boss 10 adapted to the shape of the opening can form a seal at the periphery of the opening, thereby isolating the inside and outside of the opening. Alternatively, the sealing boss 10 includes at least two spaced apart distributions from the inside to the outside, and the gaps between two adjacent sealing bosses 10 in the projection along the front-to-back direction are substantially the same, that is, the gaps between the first sealing boss 11 and the second sealing boss 12 are the same, which can further improve the stability of the structure. In addition, the gap between the two sealing bosses 10 can further play an isolation effect. See. Figure 5 The gap between the first sealing boss 11 and the second sealing boss 12 along the left-right direction is L1, and the gap between the first sealing boss 11 and the second sealing boss 12 along the left-right direction is L2. The sizes of L1 and L2 are substantially the same.

[0043] Optionally, in some embodiments of the present invention, the sealing boss 10 includes a first boss, a second boss, and a third boss spaced from the inside out. A first gap is defined between the first and second bosses, and a second gap is defined between the second and third bosses. The first gap is greater than, less than, or equal to the second gap. In other words, the three bosses form a nested structure, wherein the gaps between each of the three bosses can be equal, forming a structure that gradually expands outward around the opening. Furthermore, the first and second gaps may contain cool air, which can also be used to isolate the outside space from the opening. When a small amount of outside air enters, it can exchange heat with the cool air in the gaps and be isolated outside the innermost boss, preventing it from entering the opening. In other words, when the sealing boss 10 includes multiple bosses, it can reduce the loss of cool air caused by some of the bosses, preventing outside air from entering the container, thereby maintaining the temperature or vacuum state within the container. Of course, the sizes of the first and second gaps can also be adjusted according to actual application needs. For example, the first gap can be smaller than the second gap, or the first gap can be larger than the second gap, depending on the dimensions of the front of the barrel 100 or the dimensions of the bosses.

[0044] Combine Figure 3 and Figure 6 In some embodiments of the present invention, the sealing member 20 includes a positioning portion 21 and a sealing portion 22. The positioning portion 21 is connected to the panel 200, and the sealing portion 22 is connected to the positioning portion 21. The positioning portion 21 extends in a direction around the opening and is opposite to the sealing boss 10 in the front-to-back direction. When the panel 200 closes the opening, the sealing portion 22 abuts against the sealing boss 10. Specifically, the positioning portion 21 can position the sealing portion 22 on the panel 200 so that the sealing portion 22 extends toward the opening, thereby facilitating abutment with the sealing boss 10 when closing the opening, thereby improving the tightness of the fit between the sealing member 20 and the sealing boss 10 and improving the reliability of the seal when the opening is closed. Specifically, at least one of the sealing portion 22 or the sealing boss 10 can be a flexible structure, so that when the sealing portion 22 abuts against the sealing boss 10, it is in the form of an interference fit, thereby improving the sealing effect.

[0045] Combine Figure 3 In some embodiments of the present invention, the sealing portion 22 is configured as an arc-shaped plate that bulges rearwardly along the radial center of the opening. Specifically, the arc-shaped plate shape better accommodates the structure of the sealing boss 10, increasing the contact area between the sealing portion 22 and the sealing boss 10 and improving the sealing effect. Furthermore, the arc-shaped structure absorbs shock and vibration, offers excellent compression resistance and durability, and contributes to improved structural stability.

[0046] Combine Figure 3 In some embodiments of the present invention, the sealing portion 22 has a first side edge 221 and a second side edge 222 that are radially opposed to each other along the opening. The first side edge 221 is connected to the positioning portion 21, and the second side edge 222 is provided with a forwardly protruding portion 2221. In other words, one side of the sealing portion 22 is connected to the positioning portion 21, the middle portion protrudes toward the opening, and the other side is supported by the panel 200, forming an arc-shaped structure. When the sealing portion 22 abuts the sealing boss 10, both the panel 200 and the positioning portion 21 can provide support, thereby improving the stability of the structure.

[0047] More specifically, in some embodiments of the present invention, the positioning portion 21 is configured as a ring extending along the circumference of the opening, and the first side edge 221 of the sealing portion 22 is connected to the inner edge of the positioning portion 21. Thus, when the panel 200 closes the opening, the sealing portion 22 connected to the positioning portion 21 is also in a ring extending along the circumference of the opening to be suitable for sealing the opening, and the second side edge 222 of the sealing portion 22 passes over the positioning portion 21 and faces the rear surface of the panel 200. A clearance space is formed between the second side edge 222 of the sealing portion 22 and the rear surface of the panel 200. When the panel 200 opens the opening, the sealing portion 22 and the rear surface of the panel 200 are in a clearance space. The sealing boss 10 is not in contact, and the second side edge 222 of the sealing part 22 can be a clearance fit with the rear surface of the panel 200. When the panel 200 closes the opening, the sealing part 22 abuts against the sealing boss 10, and the sealing part 22 is squeezed. The first side edge 221 of the sealing part 22 is connected to the positioning part 21, and the positioning part 21 can provide support for the sealing part 22. The second side edge 222 of the sealing part 22 and the rear side surface of the panel 200 are subjected to the extrusion force, which can be changed from a clearance fit to an interference fit, thereby improving the connection tightness of the sealing part 22 and the sealing boss 10 after abutting, which is beneficial to improving the sealing effect.

[0048] like Figure 3 The figure shows the state of the panel 200 when the opening is closed. When the panel 200 closes the opening, the protrusion 2221 abuts against the rear surface of the panel 200. Thus, the protrusion 2221 can support the arc structure of the sealing part 22 and improve the structural stability of the sealing part 22.

[0049] Combine Figure 3 In some embodiments of the present invention, a positioning groove 201 is provided on the rear side of the panel 200, and the positioning portion 21 is provided in the positioning groove 201 to facilitate spatial arrangement. Specifically, the positioning groove 201 can both position the positioning portion 21, thereby facilitating the assembly of the positioning portion 21 and improving the compactness of the structure. In addition, after the positioning portion 21 is installed in the positioning groove 201, the positioning portion 21 does not protrude from the surface of the panel 200 or protrudes only slightly. A gap is provided between the positioning portion 21 and the arc-shaped sealing portion 22. This gap can provide deformation space when the sealing portion 22 is squeezed when the panel 200 closes the opening.

[0050] Further, combined with Figure 3In some embodiments of the present invention, a positioning groove 201 is provided on the rear side of the panel 200. The positioning portion 21 is disposed in the positioning groove 201. An abutting portion 211 is provided on the front side of the positioning portion 21. The abutting portion 211 abuts against the inner bottom surface of the positioning groove 201. An abutting portion 211 is further provided between the main body of the positioning portion 21 and the inner bottom surface of the positioning groove 201. The abutting portion 211 directly contacts the inner bottom surface of the positioning groove 201, so that the main body of the positioning portion 21 and the inner bottom surface of the positioning groove 201 have a clearance fit. When the positioning portion 21 is subjected to pressure, the abutting portion 211 can play a buffering and supporting role, thereby further enhancing the sealing effect of the sealing member 20.

[0051] Combine Figure 6 In some embodiments of the present invention, the fresh-keeping container 1000 further includes a drawer 300. The drawer 300 is disposed in the storage cavity 101 and is connected to the panel 200. The drawer 300 is provided with a storage cavity 301. This configuration makes it easier for users to take items in and out. During use, the user can use the handle to drive the panel 200 to pull the drawer 300 out of the storage cavity 101. At this time, the items in the storage cavity 301 can be taken out along with the drawer 300, making it easier for the user to take them out. After the user places the items in the storage cavity 301, the user can use the handle to drive the panel 200 to push the drawer 300 back into the storage cavity 101. At this time, the items in the storage cavity 301 can be brought in along with the drawer 300, improving user convenience.

[0052] In some embodiments of the present invention, the barrel body 100 is provided with an exhaust port for connecting to an exhaust device, and the exhaust port is connected to the storage cavity 101. The exhaust port can be connected to an external exhaust device. The exhaust device extracts the gas in the storage cavity 101 to form a low-pressure environment in the storage cavity 101. At this time, the bacteria and other organisms in the storage cavity 101 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 101; optionally, a vacuum environment can be created in the storage cavity 101 through the exhaust port to further improve the preservation effect of the fresh-keeping container 1000.

[0053] In some embodiments of the present invention, the fresh-keeping container 1000 also includes an exhaust component, which is connected to the storage cavity 101. The exhaust component can extract the gas in the storage cavity 101 to form a low-pressure environment in the storage cavity 101. At this time, the bacteria and other organisms in the storage cavity 101 have reduced activity in the low-pressure environment, thereby preserving the items in the storage cavity 101.

[0054] In some embodiments of the present invention, the panel 200 is provided with a support portion, which is arranged on the inner side of the inner wall surface of the barrel body 100 when the panel 200 is closed, and is used to provide support when the inner wall surface of the barrel body 100 is deformed inward. The supporting force of the support portion on the barrel body 100 can reduce the deformation of the barrel body 100 and improve the relative stability of the structure between the panel 200 and the barrel body 100.

[0055] The support portion is located inside the periphery of the opening when the panel 200 is closed, thereby improving the structural stability of the opening. Specifically, the structural strength of the opening is slightly lower than that of other parts. Therefore, arranging the support portion inside the periphery of the opening can improve the structural stability of the opening, or the structural stability of the connection between the panel 200 and the barrel body 100 in the closed position of the opening.

[0056] Furthermore, in some embodiments of the present invention, when the panel 200 is closed, the support portion is opposite to the middle position of the top wall of the barrel body 100 in the left-right direction in the up-down direction, which can improve the support effect and improve the balance of the support for the barrel body 100. Specifically, the barrel body 100 extends in the left-right direction, and the support portion is opposite to the top wall of the barrel body 100. When the top wall of the barrel body 100 is deformed, the support portion can support the top wall and transfer the force to both sides, thereby enhancing the bending strength and improving the aesthetics. Specifically, when the user closes the panel 200 and performs the evacuation operation, the barrel body 100 may be deformed under the action of pressure. When the inner wall of the barrel body 100 is bent downward under the force, the support portion can support the barrel body 100, thereby reducing the degree of deformation of the barrel body 100.

[0057] In some embodiments of the present invention, when the panel 200 is closed, the support portion abuts against the inner wall surface. In this way, when the inner wall surface is deformed, it can promptly provide support, thereby improving the support effect and protecting the barrel body 100. Alternatively, when the panel 200 is closed, there is a gap or clearance fit between the support portion and the inner wall surface. This can prevent the support portion from interfering with the inner wall of the barrel body 100 when the panel 200 moves relative to the barrel body 100, facilitating smooth drawing of the panel 200.

[0058] In some embodiments of the present invention, if the barrel body 100 or the panel 200 has been deformed, interference may occur when the panel 200 moves relative to the barrel body 100. Therefore, the fresh-keeping container may further include a roller that can cooperate with the support portion. Specifically, the inner wall surface of the barrel body 100 is provided with a roller that can rotate in the front-to-back direction. When the panel 200 is closed, the support portion and the roller are opposite. In this way, when the user pulls out the drawer, the support portion can generate rolling friction with the roller, so that the panel 200 can be smoothly pulled out. For example, when the user pulls out the panel 200, the panel 200 moves forward, the support portion moves forward, and the roller in contact with the support portion rotates forward or counterclockwise; when the user pushes the panel 200 back, the panel 200 moves forward and the support portion moves backward, and the roller in contact with the support portion rotates backward or clockwise.

[0059] A fresh-keeping container 1000 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0060] Among related technologies, refrigerator vacuum preservation technology creates a vacuum-sealed environment to isolate food from the outside air, achieving the effects of anti-bacteria, moisture-proof and anti-oxidation; the core is to use high pressure to extract the air in the container and food, so that the food is in a vacuum state, thereby effectively inhibiting the reproduction of aerobic bacteria and delaying the oxidation process of food.

[0061] To this end, the utility model proposes a fresh-keeping container 1000 with a sealing structure, in which at least one circular boss structure, namely a sealing boss 10, is provided at a position where the sealing boss 20 of the panel 200 is in contact with the sealing boss 20. When the sealing boss 10 is compressed and fitted with the sealing boss 20, the elastic sealing portion 22 of the sealing boss 20 forms multiple arc-shaped seals to enhance the sealing effect.

[0062] Specifically, the vacuum module is composed of a vacuum barrel body 100100 and a vacuum drawer 300 assembly. The vacuum drawer 300 assembly may include a panel 200 and a drawer 300. The vacuum barrel body 100 is an integrated barrel structure or a barrel-shaped structure with an open side formed by gluing or ultrasonically welding two upper and lower parts. The vacuum drawer 300 assembly is installed with a flexible or elastic sealing member 20 structure at a position facing the vacuum barrel body 100. The sealing member 20 structure is generally made of silicone, S-PVC or other soft materials that meet food-grade safety standards. The sealing member 20 structure is arranged between the open surface of the vacuum barrel body 100 and the panel 200 to seal the vacuum module. The vacuum barrel body 100 is provided with at least one "U"-shaped small boss structure, namely a sealing boss 10, at a position in contact with the seal 20. The sealing boss 10 faces the seal 20 of the panel 200. During use, when the sealing boss 10 and the sealing member 20 are compressed and fitted together, the elastic sealing portion 22 of the sealing member 20 forms a plurality of arc-shaped seals, which can enhance the sealing effect.

[0063] The present invention also provides a low-temperature fresh-keeping device, which includes a body, a refrigeration device and the fresh-keeping container 1000 in the above embodiment.

[0064] The machine body is provided with a refrigeration compartment, a refrigeration device is provided in the machine body for cooling the refrigeration compartment, and the fresh-keeping container 1000 is provided in the refrigeration compartment. By applying the aforementioned fresh-keeping container 1000, the user's safety can be improved and the user's hand injury can be avoided.
