[0036] Combination Figure 1-4 As shown, in some embodiments, a device for sealing food ingredients includes: a housing 100 and a drawer 200. The housing 100 defines a sealing cavity 110 with an opening 111 at one end; the drawer 200 is slidably disposed within the sealing cavity 110 through the opening 111; it also includes: a sealing cover 300, an elastic sealing ring 400, and a transmission mechanism. The sealing cover 300 is fixedly connected to one end of the drawer 200 and is movably disposed within the opening 111, capable of closing the sealing cavity 110; the elastic sealing ring 400 is sleeved around the periphery of the sealing cover 300; the transmission mechanism is disposed on the sealing cover 300 and connected to the elastic sealing ring 400, capable of driving the elastic sealing ring 400 to expand and press against the inner wall of the sealing cavity 110, thereby sealing the sealing cavity 110.

[0037] The food sealing device provided in this embodiment allows food that needs to be sealed and preserved to be placed in drawer 200. Drawer 200 is then pushed into the sealing cavity 110 defined by housing 100. A sealing cover 300 located at one end of drawer 200 is positioned at opening 111. An elastic sealing ring 400, which is sleeved around the sealing cover 300, is driven by a transmission mechanism to move and contact the inner wall of housing 100 at opening 111, causing it to be squeezed and deformed. This seals the opening 111 of sealing cavity 110, thereby better sealing the sealing cavity 110, improving the sealing effect of food preservation, and reducing the cost of food preservation.

[0038] Optionally, drawer 200 has a cuboid structure with sliders 210 on both ends of its width direction. A slide rail 120 is provided on the inner wall of the sealed cavity 110 corresponding to the position of the sliders 210, and the sliders 210 are confined within the slide rail 120 for sliding. In this way, through the structural cooperation of the sliders 210 and the slide rail 120, drawer 200 is slidably positioned within the sealed cavity 110. Drawer 200 can be pulled out of the sealed cavity 110 to place the food to be stored into it, and then the drawer 200 can be pushed back into the sealed cavity 110 for sealing and preservation. This improves the sealing effect of food preservation and reduces the cost of food preservation.

[0039] Optionally, the slider 210 extends along the length of the drawer 200, and the length of the slide rail 120 is greater than or equal to the length of the slider 210. This makes the slider 210, which is located on both ends of the drawer 200 in the width direction, a long strip structure, allowing the slider 210 to slide more stably within the slide rail 120, thus improving the stability of the drawer 200 when it is pulled out.

[0040] Optionally, a stop 211 is provided at one end of the slide rail 120 near the opening 111. In this way, when the drawer 200 is pulled out, the stop 211 can block the slider 210, preventing the drawer 200 from being pulled out and falling down due to excessive pulling force, thus improving the user experience.

[0041] Optionally, the sealing cover 300 includes a flat portion 310 and a mounting base 320. The flat portion 310 is attached to one end of the drawer 200; the mounting base 320 is disposed around one side of the flat portion 310, and an elastic sealing ring 400 is fitted onto the mounting base 320. In this way, by attaching one side of the flat part 310 to one end of the drawer 200, the connection between the sealing cover 300 and the drawer 200 is more secure, making it easier for the user to operate the sealing cover 300 to pull out the drawer 200. When the drawer 200 is pushed into the sealing cavity 110, the sealing cover 300 is located inside the opening 111 of the sealing cavity 110. When the elastic sealing ring 400 on the mounting base 320 is expanded by the transmission mechanism, it can better contact the inner wall of the sealing cavity 110 at the opening 111. The elastic sealing ring 400 deforms and better cooperates with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110 and improving the sealing effect of food preservation.

[0042] Optionally, the flat portion 310 is a rectangular plate structure, with one side of it abutting against one end of the drawer 200, and the mounting base 320 positioned around the perimeter of the other side. This arrangement, with one side of the flat portion 310 abutting against one end of the drawer 200 and the elastic sealing ring 400 fitted onto the mounting base 320 located around the perimeter of the other side of the flat portion 310, improves the stability between the sealing cover 300 and the drawer 200. This facilitates user operation of the sealing cover 300 to pull out the drawer 200. When the elastic sealing ring 400 is expanded by the transmission mechanism, it can better contact the inner wall of the sealing cavity 110 at the opening 111. The elastic sealing ring 400 deforms, better cooperating with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110 and improving the sealing effect for food preservation.

[0043] Optionally, the mounting base 320 protrudes vertically along the periphery of the flat portion 310. This allows the elastic sealing ring 400 to be better fitted onto the mounting base 320, improving the stability of the elastic sealing ring 400 and making it less likely to fall off under the influence of external forces.

[0044] Optionally, the mounting base 320 has a groove 321 on its outer side, and the elastic sealing ring 400 is partially embedded in the groove 321. This partial embedding of the elastic sealing ring 400 in the groove 321 makes it less likely for the elastic sealing ring 400 to fall off under external force, enhancing the stability of the elastic sealing ring 400. When the elastic sealing ring 400 is expanded by the transmission mechanism, it can better contact the inner wall of the sealing cavity 110 at the opening 111, causing the elastic sealing ring 400 to deform and better cooperate with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0045] Optionally, the resilient sealing ring 400 includes a first ring portion 410 and a second ring portion 420. The first ring portion 410 is located inside the second ring portion 420 and is connected to the inner ring surface of the second ring portion 420. This facilitates the fitting of the resilient sealing ring 400 onto the mounting base 320 and improves the stability of the fitting of the resilient sealing ring 400.

[0046] Optionally, the first ring portion 410 is embedded in the groove 321, and the second ring portion 420 is fitted over the outside of the groove 321, covering the groove 321. In this way, the first ring portion 410 embedded in the groove 321 enhances the stability of the elastic sealing ring 400, making it less likely to fall off under external force. When the elastic sealing ring 400 is driven by the transmission mechanism, the second ring portion 420 fitted over the outside of the groove 321 and covering the groove 321 can better contact and deform with the inner wall of the sealing cavity 110 at the opening 111, thereby better cooperating with the sealing cap 300 to seal the opening 111 and improving the sealing effect of the sealing cavity 110.

[0047] Optionally, the mounting base 320 is provided with a notch 322, into which the transmission mechanism extends and connects with the elastic sealing ring 400. This allows the transmission mechanism to connect with the elastic sealing ring 400 via the notch 322, minimizing the influence of the mounting base 320 on the transmission mechanism during operation. This enables the transmission mechanism to better drive the elastic sealing ring 400 to expand and contact the inner wall of the sealing cavity 110 at the opening 111, causing compression deformation. This, in turn, better cooperates with the sealing cover 300 to seal the opening 111, improving the sealing effect of the sealing cavity 110.

[0048] Optionally, the first ring portion 410 of the elastic sealing ring 400 is partially embedded in the groove 321, while the remaining portion is located in the notch 322. This enhances the overall stability of the elastic sealing ring 400, making it less likely to fall off under external force. It also facilitates the connection of the transmission mechanism into the notch 322, allowing the transmission mechanism to better drive the elastic sealing ring 400 to expand and contact the inner wall of the sealing cavity 110 at the opening 111, causing compression deformation. This better cooperates with the sealing cap 300 to seal the opening 111, improving the sealing effect of the sealing cavity 110.

[0049] Optionally, the transmission mechanism extends into the notch 322 and connects with the first ring portion 410 of the elastic sealing ring 400. In this way, the transmission mechanism can drive the first ring portion 410 to expand, thereby driving the second ring portion 420 to expand, so that the elastic sealing ring 400 can better contact the inner wall of the sealing cavity 110 at the opening 111 and be squeezed and deformed, thereby better cooperating with the sealing cover 300 to seal the opening 111 and improving the sealing effect of the sealing cavity 110.

[0050] Combination Figure 5-8 As shown, in some optional embodiments, the transmission mechanism includes a support member 500 and a drive unit. The support member 500 is slidably connected to the sealing cover 300, and one end is connected to the elastic sealing ring 400; the drive unit is connected to the other end of the support member 500, and can drive the support member 500 to slide, thereby causing the elastic sealing ring 400 to expand. Thus, when the drawer 200 is pushed into the sealing cavity 110, the sealing cover 300 is located inside the opening 111 of the sealing cavity 110. The drive unit can drive the support member 500 to slide on the sealing cover 300. The sliding support member 500 can cause the elastic sealing ring 400 to expand, thereby causing the elastic sealing ring 400, which is fitted around the sealing cover 300, to expand to contact the inner wall of the sealing cavity 110 at the opening 111, and to deform against the inner wall of the sealing cavity 110. This better cooperates with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110 and improving the sealing effect for food preservation.

[0051] Optionally, the support member 500 is slidably connected to the side of the flat portion 310 where the mounting base 320 is located, and is situated inside the mounting base 320. In this way, since the elastic sealing ring 400 is fitted onto the mounting base 320, the support member 500 is slidably positioned inside the mounting base 320, allowing for better connection between the support member 500 and the elastic sealing ring 400 fitted onto the mounting base 320, facilitating the expansion of the elastic sealing ring 400 by the support member 500.

[0052] Optionally, the flat portion 310 has a fixed guide block 311 on one side where the mounting base 320 is located. The support member 500 has a guide groove 510 corresponding to the guide block 311. The guide block 311 is engaged in the guide groove 510, and the support member 500 is slidably connected to the guide block 311 via the guide groove 510. Thus, the fixed guide block 311 is engaged in the guide groove 510 on the support member 500, and the support member 500 is slidably mounted on the side of the flat portion 310 where the mounting base 320 is located via the guide groove 510. When the support member 500 is driven by the driving unit, the guide block 311 guides the support member 500, causing it to slide along the side of the flat portion 310 where the mounting base 320 is located. This allows the support member 500 to better drive the elastic sealing ring 400 to expand, contacting and deforming the inner wall of the sealing cavity 110 at the opening 111, better cooperating with the sealing cap 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0053] Optionally, the end of the support member 500 connected to the elastic sealing ring 400 is provided with a connecting seat 520, and the connecting seat 520 extends into the notch 322 and connects with the elastic sealing ring 400. In this way, the support member 500 is connected to the elastic sealing ring 400 through the connecting seat 520 at one end, which increases the contact area between the support member 500 and the elastic sealing ring 400. When the support member 500 is driven by the driving unit, the connecting seat 520 at one end of the support member 500 can better drive the elastic sealing ring 400 connected to it to expand, so that the elastic sealing ring 400 can better contact and compress and deform with the inner wall of the sealing cavity 110 at the opening 111, and better cooperate with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0054] Optionally, the connecting seat 520 is provided with a clamping groove, and the clamping groove and the groove 321 are on the same plane. In this way, the first ring portion 410 of the elastic sealing ring 400 can be embedded in the clamping groove and connected to the connecting seat 520. When the support member 500 is driven by the driving part, the connecting seat 520 located at one end of the support member 500 can better drive the elastic sealing ring 400 connected to it to expand, so that the elastic sealing ring 400 can better contact and compress and deform with the inner wall of the sealing cavity 110 at the opening 111, and better cooperate with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0055] Optionally, the connecting seat 520 is connected to the first ring portion 410 of the elastic sealing ring 400. In this way, since the first ring portion 410 of the elastic sealing ring 400 is embedded in and connected to the connecting seat 520, and the second ring portion 420 is attached to the outer side of the connecting seat 520, when the support member 500 is driven by the driving part, the connecting seat 520 at one end of the support member 500 can better drive the elastic sealing ring 400 connected to it to expand, allowing the elastic sealing ring 400 to better contact and deform with the inner wall of the sealing cavity 110 at the opening 111, better cooperate with the sealing cover 300 to seal the opening 111, and thus better seal the sealing cavity 110.

[0056] Optionally, four support members 500 are provided, each connected to the elastic sealing ring 400, and the four support members 500 are evenly arranged around the periphery of the side of the planar portion 310 where the mounting seat 320 is located. This allows the four support members 500 to connect evenly to the elastic sealing ring 400. When the support member 500 is driven, it can fully drive the elastic sealing ring 400 to expand radially, allowing for better contact, compression, and deformation with the inner wall of the sealing cavity 110 at the opening 111, and better cooperation with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0057] Optionally, the four support members 500 are located at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions on the side of the flat portion 310 where the mounting base 320 is located. This allows the four support members 500 to connect to the elastic sealing ring 400 at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions respectively. When the support members 500 are driven, they can fully drive the elastic sealing ring 400 to expand radially, allowing for better contact and deformation with the inner wall of the sealing cavity 110 at the opening 111, and better cooperation with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0058] Optionally, the drive unit includes a pressing part 600 and a movable connecting rod 610. The pressing part 600 is movably disposed at the center of the sealing cover 300 and can move in a direction perpendicular to the sealing cover 300. When the pressing part 600 is in the first position, the elastic sealing ring 400 is expanded by the support member 500. When the pressing part 600 is in the second position, the elastic sealing ring 400 returns to its original state. One end of the movable connecting rod 610 is rotatably connected to the support member 500, and the other end is rotatably connected to the pressing part 600. Thus, since the pressing part 600 is rotatably connected to one end of the movable connecting rod 610, and the support member 500 is rotatably connected to the other end of the movable connecting rod 610, when the pressing part 600 is pressed to the first position, the pressing part 600 drives the movable connecting rod 610 to move, and the movable connecting rod 610 drives the support member 500 to slide. The support member 500 then drives the elastic sealing ring 400 sleeved on the mounting base 320 to expand, allowing the elastic sealing ring 400 to contact and deform against the inner wall of the sealing cavity 110 at the opening 111, thus sealing the opening 111 with the sealing cover 300. To release the seal of the sealing cavity 110, the pressing part 600 is moved to the second position. The pressing part 600 then drives the movable connecting rod 610 to move. The movable connecting rod 610 drives the support member 500 to slide. The expanded elastic sealing ring 400 returns to its original state under the action of the support member 500 and its own elasticity, thus releasing the seal of the sealing cavity 110. By operating the pressing part 600, the elastic sealing ring 400 can be expanded to seal the sealing cavity 110, or the elastic sealing ring 400 can be restored to its original state to release the seal of the sealing cavity 110, which is convenient for the user.

[0059] Optionally, the pressing part 600 is movably positioned at the center of the side of the flat part 310 where the mounting base 320 is located, and can move in a direction perpendicular to the flat part 310. Since the support member 500 is slidably connected to the side of the flat part 310 where the mounting base 320 is located, movably positioning the pressing part 600 at the center of the side of the flat part 310 where the mounting base 320 is located facilitates the connection between the pressing part 600 and the support member 500 via the movable connecting rod 610. This allows the pressing part 600 to better drive the support member 500 to move, thereby better expanding the elastic sealing ring 400 through the support member 500.

[0060] Optionally, the sealing cover 300 further includes a protective cover 330. The protective cover 330 covers the side of the flat portion 310 where the mounting base 320 is located, and the transmission mechanism is located inside the protective cover 330. In this way, the protective cover 330 can isolate the transmission mechanism mounted on the sealing cover 300 from the external environment, making the transmission mechanism less susceptible to external environmental contamination and extending the service life of the transmission mechanism.

[0061] Optionally, a pressing hole 331 is provided on the cover 330 at a position corresponding to the pressing part 600, and the pressing part 600 is movably disposed within the pressing hole 331. In this way, the pressing part 600 is connected to the support member 500 through the pressing hole 331 on the cover 330 via the movable connecting rod 610. The pressing hole 331 not only facilitates the installation of the pressing part 600, but also guides the movement of the pressing part 600, allowing the pressing part 600 to move in a direction perpendicular to the sealing cover 300.

[0062] Optionally, the pressing part 600 is provided with a claw 620 at one end facing the flat part 310. In this way, when the pressing part 600 moves within the pressing hole 331, the claw 620 can be engaged with the inner wall of the pressing hole 331, thereby restricting the pressing part 600 to a second position and preventing the pressing part 600 from coming out of the pressing hole 331.

[0063] Combination Figure 9-12As shown, in some optional embodiments, the driving unit further includes a limiting structure 700. The limiting structure 700 is fixedly disposed at the center of the sealing cover 300 and can limit the pressing part 600 to a first position. Thus, when the pressing part 600 is pressed to the first position, the pressing part 600 drives the support member 500 to move through the movable connecting rod 610. The support member 500 can drive the elastic sealing ring 400 sleeved around the sealing cover 300 to expand to contact the inner wall of the sealing cavity 110 at the opening 111, and deform it by squeezing it against the inner wall of the sealing cavity 110. This cooperates with the sealing cover 300 to seal the opening 111 of the sealing cavity 110. The limiting structure 700 can limit the pressing part 600 to the first position, keeping the elastic sealing ring 400 in an expanded state, which can better cooperate with the sealing cover 300 to seal the opening 111 of the sealing cavity 110, thereby improving the sealing effect of food preservation.

[0064] Optionally, a guide rod 630 is provided at the center of the side of the pressing part 600 facing the limiting structure 700. One end of the guide rod 630 is fitted with a rotatable guide member 640, and the outer wall of the guide member 640 is provided with locking teeth 641. In this way, when the pressing part 600 is moved to the first position, the guide rod 630 extends into the limiting structure 700, and the guide member 640 on the guide rod 630 rotates under the action of the limiting structure 700. After rotation, the locking teeth 641 on the outer wall of the guide member 640 can be locked into the limiting structure 700. The limiting structure 700 restricts the pressing part 600 to the first position, keeping the elastic sealing ring 400 in an expanded state. This allows for better cooperation with the sealing cap 300 to seal the opening 111 of the sealing cavity 110, improving the sealing effect for food preservation.

[0065] Optionally, the limiting structure 700 includes a guide seat 710 and a limiting seat 720. The guide seat 710 is fixedly disposed at the center of the side of the flat portion 310 where the mounting seat 320 is located; the limiting seat 720 is located at the end of the guide seat 710 facing the pressing portion 600, and is fixedly connected to the guide seat 710 via a clamping arm 721. Thus, when the pressing portion 600 moves to the first position, the guide member 640 on the guide rod 630 extends out of the limiting seat 720 and enters the guide seat 710. The guide member 640 on the guide rod 630 rotates under the action of the guide seat 710, and the retaining teeth 641 on the outer wall of the rotated guide member 640 can engage with the limiting seat 720. The limiting seat 720 restricts the pressing portion 600 to the first position, keeping the elastic sealing ring 400 in an expanded state, which can better cooperate with the sealing cap 300 to seal the opening 111 of the sealing cavity 110, thereby improving the sealing effect of food preservation.

[0066] Optionally, the guide seat 710 is a cylindrical structure, and its inner side wall is provided with guide teeth 711 that intersect with the locking teeth 641; the limiting seat 720 is also a cylindrical structure, and its inner side wall is provided with tooth grooves 722 corresponding to the position of the locking teeth 641, and the end of the limiting seat 720 facing the guide seat 710 is provided with limiting teeth 723 that intersect with the locking teeth 641. Thus, when the pressing part 600 moves to the first position, the guide member 640 on the guide rod 630 extends out of the limiting seat 720 and into the guide seat 710. Since the inner side wall of the guide seat 710 is provided with guide teeth 711 that intersect with the locking teeth 641, the locking teeth 641 on the outer side wall of the guide member 640 drives the guide member 640 to rotate under the action of the guide teeth 711. After the locking teeth 641 rotate, they can be locked into the limiting teeth 723 on the limiting seat 720 that intersect with the locking teeth 641, thereby restricting the pressing part 600 to the first position and keeping the elastic sealing ring 400 in an expanded state. This allows it to better cooperate with the sealing cover 300 to seal the opening 111 of the sealing cavity 110, improving the sealing effect of food preservation.

[0067] Optionally, a return spring 730 is sleeved on the outer side of the guide seat 710 and the limiting seat 720, with one end of the return spring 730 connected to the flat part 310 and the other end connected to the pressing part 600. Thus, when it is necessary to release the seal of the sealing cavity 110, pressing the pressing part 600 again causes the guide member 640 on the guide rod 630 to extend back into the guide seat 710. The locking tooth 641, under the action of the guide tooth 711, drives the guide member 640 to rotate again. After rotation, the locking tooth 641 intersects with the limiting tooth 723 again, and the limiting tooth 723 no longer restricts the movement of the locking tooth 641. Under the action of the return spring 730, the locking tooth 641 retracts into the tooth groove 722 of the limiting seat 720. The pressing part 600 moves to the second position under the action of the return spring 730, and the seal of the sealing cavity 110 is released.

[0068] Optionally, when the pressing part 600 is in the second position, the guide member 640 on the guide rod 630 retracts into the limiting seat 720, and the retaining teeth 641 on the outer wall of the guide member 640 are located within the tooth groove 722 on the inner wall of the limiting seat 720. This prevents the guide member 640 from dislodging from the limiting seat 720, and ensures that the retaining teeth 641 on the outer wall of the guide member 640 are always located within the tooth groove 722 on the inner wall of the limiting seat 720, facilitating the reoperation of the pressing part 600 to the first position to seal the sealing cavity 110.

[0069] Combination Figure 13As shown, in some optional embodiments, the driving part includes a turntable portion 800 and a protrusion portion 810. The turntable portion 800 is rotatably disposed at the center of the sealing cover 300 and is slidably connected to the support member 500; the protrusion portion 810 is disposed around the periphery of the turntable portion 800, and when the turntable portion 800 rotates, the protrusion portion 810 can drive the support member 500 to slide, thereby causing the elastic sealing ring 400 to expand. In this way, by driving the turntable 800 to rotate, the turntable 800 drives the protrusion 810 set around its periphery to move. Since the turntable 800 and the support member 500 are slidably connected, the moving protrusion 810 can contact the support member 500, providing a supporting force to the support member 500. This causes the support member 500 to drive the elastic sealing ring 400, which is sleeved around the sealing cover 300, to expand to contact the inner wall of the sealing cavity 110 at the opening 111. The ring is squeezed and deformed against the inner wall of the sealing cavity 110, better cooperating with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110 and improving the sealing effect of food preservation.

[0070] Optionally, a rotary handle is provided axially on the turntable section 800. This allows the turntable section 800 to be rotated by operating the rotary handle, facilitating user operation and reducing user workload.

[0071] Optionally, the end of the support member 500 connected to the turntable 800 is provided with a recessed portion 820. When the turntable 800 rotates, the protrusion 810 can be engaged in the recessed portion 820 to fix the protrusion 810. In this way, when the turntable 800 rotates, the protrusion 810 moves to the position of the recessed portion 820 on the support member 500 and can be engaged in the recessed portion 820 for fixation. This keeps the support member 500 in a state that drives the elastic sealing ring 400 to expand. Keeping the elastic sealing ring 400 in an expanded state allows it to better cooperate with the sealing cap 300 to seal the opening 111 of the sealing cavity 110, improving the sealing effect for food preservation.

[0072] Optionally, the height of the protrusion 810 along the plane of the turntable 800 is greater than or equal to twice the depth of the recess 820. This allows the protrusion 810 to apply a stronger supporting force to the support member 500 when it is engaged within the recess 820. This enables the support member 500 to better drive the expansion of the elastic sealing ring 400, keeping the elastic sealing ring 400 in an expanded state. This better cooperates with the sealing cap 300 to seal the opening 111 of the sealing cavity 110, improving the sealing effect for food preservation.

[0073] Optionally, the protrusion 810 is an arc-shaped protrusion, and the recess 820 is an arc-shaped recess. In this way, when the turntable 800 rotates, the protrusion 810 can smoothly engage with the recess 820, and when it is necessary to release the seal of the sealing cavity 110, the protrusion 810 can smoothly slide out of the recess 820, allowing the support member 500 to return to its original position under the elastic action of the elastic sealing ring 400, facilitating user operation.

[0074] Optionally, four protrusions 810 are provided, located at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions of the turntable 800, respectively. Thus, with four support members 500 located at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions on the side of the flat portion 310 where the mounting base 320 is located, the four protrusions 810 drive the four support members 500 to move simultaneously with the turntable 800. This allows the support members 500 to fully drive the elastic sealing ring 400 to expand radially, better contacting and deforming it against the inner wall of the sealing cavity 110 at the opening 111, and better cooperating with the sealing cover 300 to seal the opening 111, thereby better sealing the sealing cavity 110.

[0075] Combination Figure 14 As shown, in some embodiments, a refrigerator includes the device for sealing food according to any of the above embodiments.

[0076] Optionally, the refrigerator also includes a refrigerator compartment. A device for sealing food is movably disposed within the refrigerator compartment. This allows the food-sealing device, containing stored food, to be placed inside the refrigerator compartment, further enhancing its preservation effect.
