NOVELTY - The device has a housing space that is installed on the upward surface of a box casing. A heating pad and a cooling pad are electrically connected to the circuit components are installed in the housing space. The heating pad has one or more arc-shaped structure. The cooling pad is positioned between the inner side of the arc surface of the heating pad and the side wall of the housing space, and is further provided with a heat transfer plate. The heat transfer plate is placed in contact with or adjacent to the cooling pad or heating pad, and is parallel to the inner surface of the housing space or forms an included angle of 10 to 20 degrees. The heating pad is a graphene heating sheet, a PI heating sheet, or a poly(ethyl benzene-1,4-dicarboxylate) (PET) heating sheet. The heat transfer plate is made of an aluminum alloy material. USE - Temperature control device used for cosmetics such as beauty mask and cream. ADVANTAGE - The user can freely switch heating or cooling as necessary. The user does not feel hot and hot when using a beauty mask in the summer season. The overall structure of the product is simple. The design structure is rational. The potential to be used in a strong industry is improved.
