摘要： The present invention provides a beauty instrument, comprising: a housing with vents therethrough as an air inlet or air outlet; a control circuit board in the housing; a light source assembly in the housing and electrically connected with the control circuit board; and a thermoelectric cooling assembly. The thermoelectric cooling assembly comprises: a thermoelectric cooler, a heat sink, a fan, and a heat transfer assembly. The heat transfer assembly comprises a VC or an ALVC or an Aluminum Heat Pipe. The heat transfer assembly is thermally connected between the heat sink and the hot side of thermoelectric cooler. A front end of the beauty instrument has a light outlet surface; the cold side is connected to and cool the light outlet surface, or the cold side serves as the light outlet surface, thereby, the light outlet surface is able to cool skin in contact.

摘要： The present invention relates to a hair removal device and a Peltier cooler. The hair removal device comprises a hair removal head, a light source assembly, a power supply unit, and a control circuit board; the power supply unit supplies power to the light source assembly, and the control circuit board controls the light source assembly to generate pulsed light; a transparent medium body is mounted on the hair removal work head to serve as a hair removal work surface coming into contact with skin so as to form a transparent medium hair removal work surface. The Peltier cooler comprises a semiconductor pillar layer, and a hot surface and a cold surface at two ends of the semiconductor galvanic couple layers; the cold surface is a transparent crystal so as to form a transparent crystal cold surface.
