[0049] As shown in Figure 1 In one embodiment, the refrigeration device 10 includes a cabinet 100 and a magnetic field fresh-keeping container 200. The cabinet 100 is provided with a storage compartment 101. The magnetic field fresh-keeping container 200 is arranged in the storage compartment 101. The magnetic field fresh-keeping container 200 is the magnetic field fresh-keeping container described in any of the embodiments below.

[0050] As shown in Figures 2 to 5 In one embodiment, the magnetic field fresh-keeping container 200 includes a storage device 210 and a magnetic field device 220. The storage device 210 is provided with a storage space 211, and the bottom side wall of the storage device 210 is provided with a sandwich space 212. The storage device 210 is provided with an opening 213 communicating with the sandwich space 212, and the opening 213 is arranged at the side edge of the sandwich space 212. The magnetic field device 220 is inserted into the sandwich space 212 through the opening 213, so as to cover at least part of the storage space 211 and generate a magnetic field in the storage space 211.

[0051] Referring toFigures 2 to 5 As shown, specifically, the storage device 210 is a drawer. The interlayer space 212 is arranged at the bottom side wall of the storage device 210, and the interlayer space 212 is flat. The side edges of the interlayer space 212, i.e. the side edges adjacent to the wall surface facing the storage space 211, are the front side edge, the left side edge, the right side edge and the rear side edge of the interlayer space 212. In the embodiment, the opening 213 is formed at the front side edge of the interlayer space 212.

[0052] It should be noted that in some other embodiments, when the storage device is a drawer, the interlayer space can also be arranged at the front side wall, the left side wall, the right side wall or the rear side wall of the storage device. Alternatively, in some other embodiments, the storage device can also be a box-shaped structure, and also has a top side wall, and the interlayer space can also be arranged at the top side wall. In addition, in some other embodiments, the plurality of side walls of the storage device can each be provided with an interlayer space, or a plurality of parallel interlayer spaces are arranged on one side wall.

[0053] Continuing to refer to Figures 2 to 5 As shown, the magnetic field device 220 is also flat, and can be inserted into the interlayer space 212 from the opening 213 of the front side edge of the interlayer space 212 in the front-rear direction of the storage device 210, so that the flat surface of the magnetic field device 220 covers at least part of the storage space 211, so as to generate a magnetic field in the storage space 211, so that the stored objects stored in the storage space 211 can be affected by the magnetic field, thereby achieving the magnetic field fresh-keeping effect.

[0054] In the scheme of the embodiment, by arranging the interlayer space 212 at the side wall of the storage device 210, and arranging the opening 213 at the side edge of the interlayer space 212, the opening 213 is in communication with the interlayer space 212, so that the magnetic field device 220 can be inserted into the interlayer space 212 through the opening 213, and the magnetic field device 220 in the interlayer space 212 can cover at least part of the storage space 211 in the direction facing the storage space 211, so as to generate a magnetic field in the storage space 211. Therefore, the stored objects stored in the storage space 211 will be affected by the magnetic field generated by the magnetic field device 220 during low-temperature storage, thereby achieving magnetic field fresh-keeping and improving the fresh-keeping effect of the stored objects. Moreover, the magnetic field device 220 can be inserted into or taken out of the interlayer space 212 through the opening 213, which makes the assembly of the magnetic field device 220 in the storage device 210 more convenient on the basis of achieving the magnetic field fresh-keeping.

[0055] In addition, by arranging the interlayer space 212 at the bottom side wall of the drawer and the opening 213 at the front side edge of the interlayer space 212, since the area of the bottom side wall of the drawer is usually the largest, the interlayer space 212 can be made larger to accommodate a larger magnetic field device 220, and better cover the storage space 211. At the same time, the opening 213 is located at the front side edge of the interlayer space 212, so that the magnetic field device 220 can be taken out or installed without taking out the drawer, which is more convenient.

[0056] As shown in FIG. 2, in one embodiment, the magnetic field device 220 includes a shell 221 and a magnetic field generating element 222 arranged in the shell 221. The magnetic field generating element 222 is an element for generating a magnetic field, which is a permanent magnet in this embodiment. In other embodiments, it can also be an electromagnetic coil, etc. Figures 2 to 6

[0057] By arranging the magnetic field generating element 222 in the shell 221, the magnetic field generating element 222 can be protected from being damaged by rubbing against the inner wall of the interlayer space 212 when the magnetic field device 220 is disassembled. At the same time, the magnetic field device 220 can be fixedly connected to the storage device 210 through the shell 221, reducing the inconvenience caused by directly fixing the magnetic field generating element 222 to the storage device 210.

[0058] As shown in FIG. 2, in one embodiment, the magnetic field device 220 further includes a magnetic conducting plate 223 arranged at the side of the magnetic field generating element 222 away from the storage space 210. Specifically, the top side of the magnetic field generating element 222 faces the storage space 211, and the bottom side thereof faces away from the storage space 211, so the magnetic conducting plate 223 is arranged at the bottom side of the magnetic field generating element 222. By arranging the magnetic conducting plate 223, the magnetic field generated by the magnetic field generating element 222 can be guided to make the magnetic field more evenly distributed in the storage space 211. Figures 2 to 6 It should be noted that in other embodiments, the magnetic field device can only include the magnetic field generating element.

[0059] As shown in FIG. 2, in one embodiment, the magnetic field device 220 further includes a magnetic conducting plate 223 arranged at the side of the magnetic field generating element 222 away from the storage space 210. Specifically, the top side of the magnetic field generating element 222 faces the storage space 211, and the bottom side thereof faces away from the storage space 211, so the magnetic conducting plate 223 is arranged at the bottom side of the magnetic field generating element 222. By arranging the magnetic conducting plate 223, the magnetic field generated by the magnetic field generating element 222 can be guided to make the magnetic field more evenly distributed in the storage space 211.

[0060] Figures 2 to 6 ​​As shown, the shell 221 comprises a first shell 2211 and a second shell 2212, which are buckled to each other in the direction facing and away from the storage space 211, so as to clamp the magnetic field generating member 222 inside. Specifically, the interlayer space 212 and the magnetic field device 220 are arranged on the bottom side wall of the storage device 210 in the direction facing and away from the storage space 211, i.e. in the up-down direction, that is, the first shell 2211 and the second shell 2212 are buckled to each other in the up-down direction, so as to clamp the magnetic field generating member 222 inside. By arranging the shell 221 as the first shell 2211 and the second shell 2212 buckled to each other, the assembly of the magnetic field generating member 222 and the shell 221 is facilitated.

[0061] Referring to Figures 2 to 3 As shown, the magnetic field fresh-keeping container 200 further comprises a push-pull self-locking structure (not shown in the figure), which is arranged between the shell 221 and the storage device 210. The shell 221 is movable between a closed position in which the surface of the shell 221 facing the outside of the interlayer space 212 in the direction of the opening 213 is flush with the opening 213, a pressed position in which the surface of the shell 221 facing the outside of the interlayer space 212 in the direction of the opening 213 is recessed in the opening 213, and a popped-out position in which the surface of the shell 221 facing the outside of the interlayer space 212 in the direction of the opening 213 is protruded out of the opening 213. Specifically, the push-pull self-locking structure is a mechanical structure well known to those skilled in the art, and its specific structure will not be described here. However, the installation position of the push-pull self-locking structure will be briefly described. Specifically, the shell 221 is provided with a front baffle, the length of the front baffle in the left-right direction is greater than the length of the opening 213, and the front baffle has portions extending beyond the left and right ends of the opening 213. The storage device 210 is provided with mounting grooves at the left and right ends of the opening 213, respectively, and the cooperating members of the push-pull self-locking structure can be arranged in the portions of the front baffle extending beyond the left and right ends of the opening 213 and the mounting grooves at the left and right ends of the opening 213, respectively.

[0062] As Figures 2 to 4 As shown, in one embodiment, a plurality of buffer pads 230 are arranged in the interlayer space 212, the buffer pads 230 are arranged on the side wall of the interlayer space 212 opposite to the opening 213, the buffer pads 230 are made of elastic material, and the shell 221 in the closed position presses the buffer pads 230. Specifically, the opening 213 is located at the front side edge of the interlayer space 212, and the buffer pads 230 are arranged on the rear side wall of the interlayer space 212. The buffer pads 230 are annular structures made of elastic material. When the shell 221 is in the closed position, the shell 221 presses the annular buffer pads 230, causing the buffer pads 230 to deform and accumulate elastic force to push the shell 221 out of the opening 213. When the shell 221 is unlocked, the buffer pads 230 return to their original state and assist the shell 221 to move out of the opening 213, so that the shell 221 is more easily popped out.

[0063] As Figure 2 , Figure 7and Figure 8 As shown, in one embodiment, the storage device 210 is provided with a through hole 214, which penetrates the sidewall of the interlayer space 212 and connects with the opening 213. A limiting groove 224 is provided on the surface of the outer shell 221 facing the through hole 214. The magnetic field preservation container 200 also includes a guide sleeve 240, a limiting member 250, and an elastic member 260. The guide sleeve 240 is located at the end of the through hole 214 away from the interlayer space 212. A guide groove 241 is provided inside the guide sleeve 240, communicating with the through hole 214 and extending in the same direction as the through hole 214. The limiting member 250 is located within the guide groove 241, extending through the through hole 214 into the interlayer space 212 and embedding into the limiting groove 224. The elastic member 260 is located between the limiting member 250 and the guide sleeve 240, providing elasticity to allow the limiting member 250 to embed into the limiting groove 224. Furthermore, the limiting member 250 is configured to disengage from the limiting groove 224 by compressing the elastic member 260.

[0064] like Figure 2 , Figure 7 and Figure 8 As shown, specifically, opening 213 is located at the front edge of the interlayer space 212. The sidewalls of the interlayer space 212 that connect with opening 213 include a top sidewall, a bottom sidewall, a left sidewall, and a right sidewall. A through hole 214 is located on the top sidewall of the interlayer space 212, extending vertically. A limiting groove 224 is located on the top surface of the outer shell 221. The guide sleeve 240 is a cylindrical structure with one open end and one closed end; the internal space of the cylinder is the guide groove 241. The open end of the guide sleeve 240 connects to the end of the through hole 214 that is away from the interlayer space 212, meaning the guide groove 241 connects to the top of the through hole 214, and the guide groove 241 also extends vertically.

[0065] Reference Figure 2 , Figure 7 and Figure 8 As shown, the limiting member 250 is a cylindrical structure with an outer diameter smaller than the inner diameter of the guide groove 241, allowing it to be positioned within the guide groove 241. Furthermore, the length of the limiting member 250 allows it to pass through the through hole 214 into the interlayer space 212, thus embedding itself into the limiting groove 224 in the vertical direction. After the limiting member 250 is embedded in the limiting groove 224, it hinders the movement of the magnetic field device 220 outward from the opening 213, thereby preventing the magnetic field device 220 from detaching from the interlayer space 212.

[0066] In addition, the elastic member 260 is a spring arranged between the top of the limiting member 250 and the closed end of the guide sleeve 240. When the limiting member 250 is embedded in the limiting groove 224, the limiting member 250 will press the elastic member 260, and in return, the elastic member 260 will give the limiting member 250 a downward force, i.e. the elastic force that makes the limiting member 250 embedded in the limiting groove 224. Moreover, the limiting member 250 is configured to be able to be disengaged from the limiting groove 224 by pressing the elastic member 260. That is, after the limiting member 250 is embedded in the limiting groove 224, without excessive external force, the magnetic field device 220 can be limited by the cooperation of the limiting member 250 and the limiting groove 224, and when subjected to a larger external force, i.e. when the user pulls the magnetic field device 220 outward, the limiting member 250 can be pressed upward to press the elastic member 260, so that the limiting member 250 is disengaged from the limiting groove 224.

[0067] In the scheme of the present embodiment, by arranging the through hole 214 in the storage device 210, arranging the limiting groove 224 on the surface of the shell 221 facing the through hole 214, making the guide groove 241 of the guide sleeve 240 communicate with the through hole 214, and arranging the limiting member 250 in the guide groove 241 and the elastic member 260 between the limiting member 250 and the guide sleeve 240, the limiting member 250 can be embedded in the limiting groove 224, thereby hindering the movement of the magnetic field device 220 to the outside of the opening 213, and further playing a role in preventing the magnetic field device 220 from being disengaged from the interlayer space 212. Moreover, the elastic member 260 can provide the elastic force that makes the limiting member 250 embedded in the limiting groove 224, thereby enhancing the limiting effect. In addition, the limiting member 250 is configured to be able to be disengaged from the limiting groove 224 by pressing the elastic member 260, i.e. under certain conditions, the limiting member 250 can be automatically disengaged from the limiting groove 224 by directly pulling the magnetic field device 220 outward, thereby simplifying the operation.

[0068] It should be noted that in some other embodiments, only the through hole, the limiting groove and the limiting member can be arranged, and each time the user manually inserts the limiting member from the outside into the limiting groove through the through hole to form the limiting, or manually pulls out the limiting member to release the limiting.

[0069] As shown in Figure 2 , Figures 7 to 9 , the guide sleeve 240 is provided with an avoiding hole 242, and the limiting member 250 is provided with an operating rod 251, the operating rod 251 extends to the outside of the guide sleeve 240 through the avoiding hole 242, and the avoiding hole 242 is configured to enable the operating rod 251 to reciprocate in the extension direction of the guide groove 241, thereby driving the limiting member 250 to compress the elastic member 260 and disengage from the limiting groove 224.

[0070] As shown in Figure 2 , Figures 7 to 9As shown, the avoiding hole 242 is arranged on the side wall of the guide sleeve 240 and has a certain length in the up-down direction. The operating rod 251 extends radially from the side of the limiting piece 250 and extends to the outside of the guide sleeve 240 through the avoiding hole 242. By moving the operating rod 251 up and down in the avoiding hole 242, the limiting piece 250 can be driven to move up and down.

[0071] By arranging the avoiding hole 242 on the guide sleeve 240 and the operating rod 251 on the limiting piece 250, the user can manually disengage the limiting piece 250 from the limiting groove 224 by controlling the operating rod 251, which helps to manually release the limiting in the case of the limiting piece 250 being stuck and improves the flexibility of use. At the same time, the operating rod 251 and the avoiding hole 242 can also prevent the limiting piece 250 from falling out of the guide groove 241.

[0072] As shown in Figure 2 , Figures 7 to 9 The limiting piece 250 is provided with a guide surface 252 and a limiting surface 253. The guide surface 252 is arranged on the side of the limiting piece 250 facing the opening 213. The limiting surface 253 is arranged on the side of the limiting piece 250 away from the opening 213, and the limiting surface 253 is perpendicular to the axis of the opening 213. The limiting piece 250 abuts against the limiting groove 224 through the limiting surface 253. Specifically, the guide surface 252 is an inclined surface, and the limiting surface 253 is a vertical surface. During the process of inserting the magnetic field device 220 into the interlayer space 212, the guide surface 252 is always in contact with the guide surface 252, facilitating movement. When the limiting piece 250 is embedded in the limiting groove 224, the limiting piece 250 abuts against the limiting groove 224 through the limiting surface 253, making it difficult to disengage the limiting piece 250 from the limiting groove 224 by pulling the magnetic field device 220 alone, so that the limiting effect is stronger. However, because the operating rod 251 is provided, the limiting can be manually released.

[0073] As shown in Figure 2 and Figure 10 The magnetic field fresh-keeping container 200 includes a positioning protrusion 270 made of elastic material, which is arranged on the side wall of the interlayer space 212.
