The invention is a heat dissipation mechanism for improving the thermal energy problem of the internal system of the beauty device, which comprises a shell, a first shell fan and an internal circuit box.The housing comprises a first housing air hole.The first housing fan is arranged on the first housing air hole of the housing.The inner circuit box is arranged in the shell and comprises a plurality of air holes.The first housing fan supplies air to the inner side of the housing or exhausts air to the outer side of the housing, thereby improving the heat dissipation efficiency.In this way, the top of the shell no longer needs to be provided with an air vent, so as to ensure that no water will enter when cleaning； moreover, because the shell has sufficient heat dissipation efficiency, it can be equipped with a smaller shell to reduce the overall volume, so that the beauty device can be easily carried.本創作係用於改善美容裝置內部系統熱能問題的散熱機構，其包含一殼體、一第一殼體風扇及一內電路盒。殼體包含有一第一殼體風孔。第一殼體風扇設於殼體的第一殼體風孔上。內電路盒設於殼體內且包含有複數通氣孔。藉由第一殼體風扇朝向殼體內側送風，或朝向殼體外側抽風，藉此提升散熱效能。如此一來，殼體的頂端便不再需要設置通氣孔，於是能夠確保清潔時不會進水；並且，由於已具有足夠散熱效能，故能夠配置較小的殼體來降低整體體積，使美容裝置便於攜帶。
