Description

technical field [0001] The present application relates to the technical field of medical equipment, and in particular, to a household laser hair removal device. Background technique [0002] The traditional home laser hair removal instruments use edge-emitting semiconductor lasers, and the light-emitting direction of the edge-emitting semiconductor lasers is parallel to the surface of the laser substrate. The photoelectric conversion rate of the laser is low, generally 10%; and the operating temperature of the laser is 35 ℃ and below, when the temperature exceeds 35 ℃, the photoelectric conversion rate of the laser will be lower, and it will be easier to burn; some laser hair removal devices use semiconductor cooling chips to dissipate heat, but semiconductor cooling chips are used to dissipate heat to the skin. Prevent the temperature of the skin from being too high when the laser is irradiating the skin. The semiconductor cooling film is not used to dissipate the heat of t...
