[0002] As the name implies, a refrigerator magnet is a small patch that can be attached to the surface of a refrigerator. Generally, these patches are made of plastic or soft magnetic materials and are embedded with magnets or other types of magnetic substances, enabling them to firmly adhere to metal surfaces, especially on the metal casings of household appliances such as refrigerators and microwaves. Initially, the design of refrigerator magnets was mainly for decorating the home environment, adding fun and aesthetics to the kitchen or dining room. With the market demand, refrigerator magnets have gradually developed more functions, such as being used as a memo or reminder tool to help family members record shopping lists, reminders, or important dates, etc.

[0003] Specifically, refrigerator magnets are often used to remind users to buy missing ingredients or items. For example, users can place a sticky note saying "buy groceries" or "refill milk" under the refrigerator magnet and use the magnet to fix it, which is convenient for checking at any time and making a shopping plan. This function makes refrigerator magnets practical and convenient in daily life, especially suitable for places such as family kitchens and offices, and has become a part of many families' daily lives.

[0004] However, although refrigerator magnets have certain practicality in terms of function, the existing products generally have the problem of single function. Most refrigerator magnets are only used as decorations or simple memo tools, lacking the possibility of further expansion. More importantly, most of the existing refrigerator magnets only have the basic magnetic attraction function and are used as a single functional tool, lacking interactivity and fun. This single nature makes many users feel bored after using it for a long time, lacking novelty and attraction. Content of the Utility Model
