The
skin tendering instrument heat dissipation structure comprises a
light source assembly and a heat dissipation fan, the
light source assembly comprises a support, a
light source and an
optical filter, the support is provided with an inner cavity, the light source is arranged in the inner cavity of the support, a light outlet is formed in the side, opposite to the light source, of the support, and the
optical filter is arranged between the light source and the light outlet. The support is provided with a ventilation opening, and the cooling fan is connected to the ventilation opening. In the technical scheme of the utility model, the light source and the
optical filter are arranged in the inner cavity of the bracket, light rays of the light source penetrate through the optical filter and then are emitted out from the light outlet during working, and heat generated during working of the light source, the optical filter and the like passes through the inner cavity of the bracket and is subjected to air suction
convection heat dissipation by using the heat dissipation fan; therefore, the light source, the optical filter and the like are prevented from generating large temperature rise, the working efficiency and effect of the whole
photon rejuvenation instrument are improved, the temperature of the optical filter can be rapidly reduced for the use scene where the optical filter needs to be replaced, and a user is prevented from being scalded when the optical filter is replaced.
