Cosmetic plant essential oil extraction device and extraction method

The invention discloses a cosmetic plant essential oil extraction device and method, and relates to the technical field of plant essential oil extraction equipment. The device comprises a rack, a distillation retort, a condenser, an oil-water separator and a crushing box are arranged on the rack, the distillation retort, the condenser and the oil-water separator are sequentially communicated through pipelines, a through hole is formed in the distillation retort, and the crushing box is communicated with the through hole through a communicating pipe; a sealing plate for discontinuously sealing or unsealing the through hole is arranged in the distillation retort in a sliding manner. According to the device, the through hole is discontinuously blocked or unblocked by the sealing plate, so that the plant raw materials discontinuously enter the distillation tank, and the situation that the plant raw materials enter the distillation tank in a large scale, so that the plant raw materials are accumulated too much, an
