A negative ion essential oil fragrance machine vibration wave conduction cup bottom crack prevention and a variety of nozzle structure, in particular, an anion essential oil fragrance machine opens a through hole in the bottom of the vibration wave conducting cup, just can insert a rubber ring piece and oscillate from bottom to top The metal punching seat is pressed into the oscillating unit, so that the high temperature and high-speed vibration frequency generated by the oscillating unit can be prevented from causing thermal ablation and cracking on the bottom of the vibration wave conducting cup, thereby improving the conduction efficiency and preventing Leakage, extend the life of the components of the body, improve the stability of the body quality, reduce the non-performing rate and the burden of after-sales maintenance man-hours, save time and effort, and set a replaceable nozzle structure at the nozzle above the negative ion oil fragrance machine It can provide two different types of direct injection and oblique spray at the same time to meet another demand of nighttime sleep.一種負離子精油飄香機振波傳導杯底其融裂防止及多樣噴頭結構,特別是指一種負離子精油飄香機於其振波傳導杯底開設一通孔,恰可由下而上嵌入一矽膠環片、振盪器金屬沖座,再壓設入振盪單元,如此,可防止振盪單元因長時間作用所產生之高溫及高速振頻對振波傳導杯底產生熱融蝕碎裂痕現象,可提升傳導效率,防止滲漏,延長機體元件壽命,提升機體品質穩定性,減低不良率及售後維修工時支出負擔,達到省時省力目的者,並於負離子精油飄香機上方噴嘴處,設置一可替換式噴頭結構,可同時提供直噴及斜噴兩種不同型態,以滿足夜間睡眠之另一需求者。
