[0044] To address the limitations of existing beauty devices, such as their monotonous design and inability to simultaneously provide both hot and cold compress functions, this application's technical solution employs a massage head assembly with a bipolar massage head. One pole of the massage head assembly provides the hot compress function, while the other provides the cold compress function. The hot and cold compress functions can be quickly switched between the two poles to meet the different hot and cold output needs of various functions, thus improving the user experience.
