The present invention relates to an improved structure of a foot bath (drying) machine, mainly comprising a case, a mist generation oscillator, and a footrest, wherein the mist generation oscillator is arranged in an accommodation space formed by the case. The mist generation oscillator is received in liquid for generating small molecule by oscillating. The generated mist can be discharged via through holes formed on the footrest. In addition, a heating device arranged in the case can increase temperature inside the case. When a user puts feet into the mist, not only the feet can be fully moisturized and nourished, the user can also feel farm so as to increase comfortness significantly.本發明為有關於一種泡(烘)腳機結構改良,主要由殼體、水霧震盪器及踏板所組成,其中於殼體所形成的容置空間處係設有水霧震盪器,此水霧震盪器係供容置於液體內,使該液體因震盪而成為分子較小之霧氣,所產生的霧氣能經由踏板上所形成的穿孔排出,此外,設於殼體內的加熱裝置能將殼體內部溫度增加,當使用者將足部放入霧氣中不僅能讓足部充分達到保濕及滋潤肌膚外,亦可感受到溫度的存在而大幅提升整體舒適感。2...泡(烘)腳機20...殼體204...注入孔206...排出孔21...水霧震盪器22...踏板220...穿孔23...加熱裝置26...漏電偵測裝置
