Description

Technical Field

[0001] The utility model relates to the technical field of hair removal instrument heat dissipation, in particular to a safety heat dissipation structure on a pulsed light hair removal instrument. Background Art

[0002] A hair removal instrument / beauty instrument / therapeutic instrument is a comfortable and safe fashionable household product. The hair removal instrument / beauty instrument / therapeutic instrument adopts advanced spectral technology to effectively prevent the hair growth on various parts of the body and achieve permanent hair removal. The specific principle is as follows: The IPL technology is adopted and acts on the skin, which is selectively preferentially absorbed by the melanocytes in the hair follicles. Without damaging the normal skin, the heat is conducted to the deep part of the hair follicle through the cross section of the hair shaft, so that the temperature of the hair follicle rises rapidly, and the hair papilla is damaged, thereby achieving the purpose of hair removal.

[0003] A large amount of heat energy will be generated when the hair removal instrument is actually used. Especially for the lamp tube assembly at the head, the heat dissipation effect must be ensured. The quality of the heat dissipation performance directly determines the service life of the hair removal instrument. Since the heat generated during the use of the lamp tube assembly is relatively large, the existing heat dissipation structures of hair removal instruments are mainly designed around the lamp tube assembly, often ignoring the overall heat dissipation effect, resulting in generally poor heat dissipation design performance of hair removal instruments and a decrease in service life. Some even set heat dissipation through holes on the shell corresponding to the lamp tube assembly in order to ensure sufficient heat dissipation effect at the lamp tube assembly, but this will cause excess light to leak out and damage the eyes. Therefore, it is necessary to improve and solve the design defects in the heat dissipation of hair removal instruments. Summary of the Invention
