A juicer, comprising a juice press mechanism and a drive mechanism for driving the operation of the juice press mechanism. The juice press mechanism comprises a container (110) and a drum (120) rotatably disposed within same and driven by the drive mechanism, a first scraper (121a) and a second scraper (121b) mounted on the drum (120) and protruding from the turning surface thereof, and a juice outlet (111) and a pulp outlet (112) arranged on the wall of the container (110). At least two guide grooves (122) are provided on the turning surface within the drum (120)； the first scraper (121a) and the second scraper (121b) are movably positioned within the guide grooves (122), the first scraper (121a) being provided with at least one extension extending outward from same. When fruit or vegetables are introduced via an inlet (131), the drum (120) and the wall of the container (110) compress the fruit or vegetables, breaking the skin thereof and enabling the juice thereof to flow out and drain by way of the juice outlet (111). The fruit or vegetable pulp is carried along the wall of the container (110) by the scrapers (121) and expelled from the pulp outlet (112). The invention separates juice and pulp and automatically expels the pulp, while being hygienic, convenient, and time-saving.
