The invention discloses a continuous distillation and extraction device capable of increasing the extraction rate of volatile and semi-volatile components. The device is characterized in that a distillation flask is connected in series between a first distillation pipe and a water-phase distillation container, wherein a sieve plate is arranged at the bottom of the distillation flask, sieve pores are uniformly distributed in the sieve plate, the sieve plate is fixedly connected with the distillation flask, a distillate reflux extension tube is connected to the lower end of a first siphon in a sleeving manner, and the distillate reflux extension tube leads into the water-phase distillation container after penetrating through a center hole of the sieve plate. According to the device, volatile and semi-volatile components in a plant raw material with a relatively thin cell wall can be stably and efficiently extracted, respective advantages of a simultaneous distillation-extraction method and a water distillation
