Device for extracting plant essential oil

The invention discloses a device for extracting plant essential oil. A distillation step, a cooling step and a separation step are integrated; and the device comprises an electric distilling pot, a steam condenser and an oil-water separator, wherein the oil-water separator is dumbbell-shaped and comprises a conical essential oil collector positioned on the top of the oil-water separator, a hydrolat collector positioned at the bottom of the oil-water separator and a cylindrical essential oil collection display neck; the electric distilling pot is communicated with a steam condenser by a mixed steam transmission tube; the steam condenser is communicated with the upper part of the essential oil collector by a mixed condensation water output tube; and the other end of a mixed liquid backflow tube is communicated with the mixed steam transmission tube. By adopting the device, three-to-one integrated design combination of the distillation, the cooling and the separation, so that the whole machine is reasonable in p
