A heat conducting mechanism for a personal care device comprising: a heat conductor and a mounting rack, wherein, the heat conductor is fixedly mounted on the mounting rack. The heat conductor is an aluminum plate, and a bamboo fiber layer or a carbon fiber layer is arranged at a working face of the heat conductor. According to the disclosure, the aluminum plate and bamboo fibers are combined, and the aluminum plate is easy to form, low in machining requirements and low in material cost. For example, for a using face, the bamboo fibers are additionally arranged at a surface of the aluminum plate. The bamboo fibers have good breathability and high wear resistance, and have the functions of natural antibiosis, bacteriostasis, mite removal, deodorizing and ultraviolet ray resistance, and thus the effect of environmental protection is achieved.
