The present disclosure relates to a multifunctional washing and care brush with a magnetic interlayer. To address the issues of inconvenient storage, insufficient structural strength, and single functionality in existing washing and care brushes, the working surface of the main body has an embedded ferrite magnetic filler layer, which can be magnetized to adhere to an iron storage rack, forming a static magnetic field during use to provide magnetic therapy. The operating surface of the main body adopts radial reinforcing ribs and three-dimensional anti-slip protrusions, combined with high-strength materials, to reduce grip deformation and the risk of brush head breakage, optimizing storage convenience and structural strength.
