The essential oil evaporating device capable of accelerating the evaporation of the present invention includes a containing cup and a cup lid, wherein the interior of the containing cup is formed with a receiving space that is filled with liquid fuel. The containing cup has a wick, and one end of the wick is disposed in the receiving space of the containing cup. The cup lid is disposed on the cup top and has a through-hole for the wick to be inserted through. The cup lid has a lid body, and the top surface and bottom surface of the lid body has a cup lid thickness therebetween. The cup lid is equipped with an inner wall and an outer wall on the top surface of the lid body. The top part of the inner wall and the bottom surface of the lid body have a first height therebetween, the top part of the outer wall and the bottom surface of the lid body have a second height therebetween. The first height and the second height are both greater than the thickness of the cup lid. An accommodating groove is formed between the inner wall and the outer wall for accommodating essential oil. When the essential oil is placed on the cup lid, the essential oil can be evaporated by using the heat generated when the liquid fuel is burned to achieve the purpose of evaporating essential oil while being able to avoid burning the essential oil directly to lower the risk when evaporating essential oil.本發明能夠加速揮發之精油揮發裝置包括有一個容杯及一個杯蓋,容杯內形成一個容納空間,容納空間中充填液態燃料,容杯具有一個燭芯,燭芯的一端設於容納空間中,杯蓋蓋設於容杯的杯頂,杯蓋穿設有一個穿孔,穿孔供燭芯穿過,杯蓋形成有一個蓋身,蓋身的頂面與底面之間具有一個杯蓋厚度,杯蓋於蓋身的頂面設有一個內壁及一個外壁,內壁的頂部到蓋身的底面之間具有一個第一高度,外壁的頂部到蓋身的底面之間具有一個第二高度,第一高度與第二高度皆大於杯蓋厚度,內壁與外壁之間形成一個容槽,容槽容納精油,將精油放置於杯蓋上,使精油能夠利用液態燃料燃燒時所產生的熱能而揮發,而達到揮發精油的目的,同時能夠避免直接燃燒精油,降低揮發精油時的危險性。10‧‧‧精油揮發裝置20‧‧‧容杯21‧‧‧容納空間22‧‧‧燭芯23‧‧‧護套24‧‧‧通孔25‧‧‧凸緣30‧‧‧杯蓋32‧‧‧內周緣33‧‧‧外周緣34‧‧‧倒鉤35‧‧‧蓋身36‧‧‧內壁37‧‧‧外壁38‧‧‧容槽39‧‧‧插槽90‧‧‧液態燃料91‧‧‧精油H1‧‧‧第一高度H2‧‧‧第二高度T‧‧‧杯蓋厚度
