[0002] With the widespread adoption and development of household appliances, the high-capacity and high-power performance of lithium-ion batteries is receiving increasing attention. Historically, due to current collection issues, the lithium battery industry has generally believed that low-capacity conventional batteries are produced using a small cylindrical process, while high-capacity or high-power batteries are produced using a prismatic stacking process. Lithium-ion batteries possess advantages such as high energy density, small size, long storage life, and zero pollution, making them a clean energy source that the country is currently vigorously developing.

[0003] The batteries in some existing household appliances are usually designed to be rechargeable, and can be charged through a charging port. While this makes it convenient to charge the batteries in household appliances, the batteries are usually embedded inside the appliances. This means that when it is necessary to remove the outer casing or other covering structure, tools must be used to remove the battery before it can be removed, which is inconvenient and causes some trouble for users.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a detachable battery packaging structure, which realizes the detachable modular design of the battery, making disassembly and assembly convenient and improving the user experience.
