The first engagement portion 2332 bypasses the first magnet 231 and extends toward the second magnet 232 to prevent the first magnet 231 from moving away from the drawer container 210.
Similarly, the second main body part 2341 is surrounded by the second magnet 232, that is, the second main body part 2341 is located inside the second magnet 232, in other words, the second magnet 232 is sleeved outside the second main body part 2341. The second engaging part 2342 bypasses the second magnet 232 and extends toward the first magnet 231 to prevent the second magnet 232 from moving away from the drawer container 210.
Further, the first engagement portion 2332 is engaged with the second engagement portion 2342 such that the first and second magnetically permeable members 233 and 234 clamp the first and second magnets 231 and 232 to the thermal structure 240, preventing the first and second magnets 231 and 232 from moving.
Specifically, as shown in fig. 7 and 8, the magnetic field refreshing apparatus 200 further includes a magnetically conductive fixing member 235, and the magnetically conductive fixing member 235 is fixed to the first engagement portion 2332 and the second engagement portion 2342 in a mortise-and-tenon manner.

Therefore, the magnetic conductive fixing member 235 facilitates the fixing of the first linking portion 2332 and the second linking portion 2342, and the installation time is saved.
Further, in the preferred embodiment of the present invention, the heat retaining structure 240 is made of an elastic material so that the first and second magnetic conductive members 233 and 234 clamp the first and second magnets 231 and 232 together with the heat retaining structure 240, thereby tightly fixing the first and second magnets 231 and 232 to the drawer container 210.
In the present invention, the magnetic field formed by the first magnet 231, the second magnet 232, the first magnetically permeable member 233 and the second magnetically permeable member 234 completely covers the cavity of the drawer 220.
Specifically, the first magnetic conductive member 233 and the second magnetic conductive member 234 assist the first magnet 231 and the second magnet 232 to form a magnetic field with uniform strength in the drawer 220, so that the food materials in various regions in the drawer 220 can be in the same magnetic field environment, and a good magnetic field preservation environment is provided for the stored materials in the drawer 220. And the arrangement of the first magnetic conduction member 233 and the second magnetic conduction member 234 also facilitates the control of the intensity of the magnetic field formed by the first magnet 231 and the second magnet 232, and avoids the situation that the intensity of the magnetic field in the local area of the drawer 220 is too high or too low.
The first and second magnetic conductive members 233 and 234 also prevent the magnetic fields of the first and second magnets 231 and 232 from leaking, i.e., limit the magnetic fields generated by the first and second magnets 231 and 232, and more particularly, limit the magnetic fields generated by the first and second magnets 231 and 232 within the drawer 220, so that the magnetic fields act on the stored objects in the drawer 220 as much as possible. Therefore, the present invention improves the utilization of the magnetic field of the first and second magnets 231 and 232 by providing the first and second magnetic conductive members 233 and 234.
