This invention provides a magnetic field preservation storage container and a refrigerator. The magnetic field preservation storage container includes: a storage assembly defining a storage space for placing stored items; a magnet assembly including a first magnet component and a second magnet component respectively disposed on a set of opposite sides of the storage assembly, forming a magnetic field within the storage space using the first magnet component and the second magnet component; and a magnetic guiding assembly having a first magnetic guiding element corresponding to the first magnet component, a second magnetic guiding element corresponding to the second magnet component, and a magnetic guiding connector connecting the first and second magnetic guiding elements, wherein the first magnetic guiding element, the second magnetic guiding element, and the magnetic guiding connector form a ring-shaped magnetic guiding path outside the storage space. The solution of this invention forms a uniform magnetic field within the storage space with sufficient strength to improve storage quality. It has a compact structure, is easy to install, meets the needs of smart refrigerators, and satisfies users' quality requirements for smart homes and smart living.

The application discloses a Micro LED chip structure capable of reducing optical crosstalk, which comprises a substrate, an epitaxial structure located on the substrate and comprising a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer which are stacked in sequence in a direction away from the substrate, a mesa structure formed by etching the epitaxial structure, an isolation channel located between adjacent mesa structures, extending downward from the surface of the epitaxial structure, penetrating the epitaxial structure and extending to the inside of the substrate, and a sidewall reflection structure covering the sidewall surface of the isolation channel and extending to the sidewall inside the substrate at least from the sidewall of the second conductive type semiconductor layer.

The utility model relates to the technical field of baby carriages. A baby carrier wheel protection assembly comprises a baby carrier body, a detachable third wheel and a drag rod are arranged at the bottom of the front side of the baby carrier body, a protection piece used for containing the third wheel and the drag rod is arranged on one side of the baby carrier body, the protection piece comprises a detachable protection module fixed to the side of the baby carrier body, and a containing groove and a containing hole are formed in the protection module. The baby carriage wheel protection assembly is convenient to operate and use, a baby carriage has multiple functions, a trailer rod and a third wheel can be placed on the baby carriage wheel protection assembly, the wheels can be protected, and higher use requirements of users can be met. The technical problems that in the prior art, an existing baby carriage is single in structure and function, the convenience in the using process cannot be improved, wheels are prone to being damaged, related parts cannot be stored, and higher practical requirements of users cannot be met are solved.

The application discloses a refrigerator and a thawing control method of the refrigerator. The refrigerator is provided with a thawing chamber for storing and thawing food to be thawed; a temperature sensor for detecting the temperature of the food to be thawed; a thawing device for thawing the food to be thawed when starting to operate; in response to a preset thawing control instruction, the total thawing time set at present and the set temperature of the food to be thawed are obtained; the process of thawing the food to be thawed from an initial temperature to the set temperature is divided into several temperature stages, the operating parameters of the thawing device in each temperature stage are determined, and the thawing device is controlled to operate according to the corresponding operating parameters in each temperature stage. By using the application, the operating state of the thawing device can be controlled according to the thawing requirements of each temperature stage in the food thawing process, so that the nutrient loss of the thawed food is reduced while the thawing requirements are met.
