An essential oil inhaling device which includes two placing portions and a connection bar. Each of the placing portions includes at least one placing space and at least one placing hole provided at one end and in communication with each of the placing spaces. The connection bar is located between the two placing portions, and the connection bar has two ends each being connected to the outer periphery of each of the placing portions. The essential oil inhaling device has a simple structure for being conveniently placed into the nostril of a user, and the essential oil is filled in each of the placing spaces so as to achieve the effect of refreshing the nasal congestion. Furthermore, when the essential oil inhaling device is installed in the nostril, it is well concealed and does not affect the appearance of the user, causing no concerns about poor perception. In addition, each of the placing portions has a relatively round shape, which is more ergonomic and has the best support strength, thereby improving the comfort and fit feeling of the user when being worn. Besides, when the length of each of the placing portions is lengthened, the depression inside the nostril is used to enable one end of each placing portion to be jammed in the depression inside each of the two nostrils, so as to increase the support force and extend the time of use of the essential oil.一種精油吸入器，包含二置入部及一連接條。每一該置入部包含至少一置入空間及至少一開設在一端且與每一該置入空間相通的置入孔。該連接條位在該二置入部之間且該連接條的兩端分別連接每一該置入部外周圍。該精油吸入器的結構簡單能讓使用者方便設置到鼻孔，在每一該置入空間內填充精油，達到提神鼻塞的功效。且該精油吸入器裝設置到鼻孔時，其隱藏性好，不會影響使用者的外觀，故不會造成有觀感不佳的疑慮。另外，每一該置入部為較圓型，較符合人體工學及最佳支撐力度，提升使用者穿戴時的舒適感及服貼度。此外將每一該置入部之長度拉長，利用鼻孔內部的凹陷處，使每一該置入部的一端能卡掣在兩鼻孔內部的凹陷處，增加支撐力及延長精油使用時間。
