1. A vacuum juicer, characterized by comprising a vacuum cover assembly, a stirring cup assembly and a main unit, wherein the stirring cup assembly is arranged inside the vacuum cover assembly in a sleeved mode;

  • the vacuum cover assembly is movably connected with the main unit and comprises a vacuum cover and a cam arranged on the vacuum cover, the cam rotates around the vacuum cover, and a sealant is arranged on the cam and corresponds to an air inlet in the vacuum cover;

    the stirring cup assembly comprises a stirring cup holder and a stirring cup, and a movable valve is arranged at a stirring cup air hole in the stirring cup and slides up and down to control opening and closing of the stirring cup air hole;

    a vacuum pump is arranged inside the main unit and is in sealed connection with the internal space of the vacuum cover;

    a control handle is arranged above the cam and drives the cam to rotate;

    when the control handle is located at a first position, the sealant of the cam blocks the air inlet of the vacuum cover, and the movable valve slides downward to open the stirring cup air hole to provide communication between the stirring cup assembly and the vacuum cover assembly, such that both the stirring cup assembly and the vacuum cover assembly are vacuumed by the vacuum pump;

    when the control handle is located at a second position, the sealant of the cam continues to block the air inlet of the vacuum cover, and the movable valve slides upward to close the stirring cup air hole, such that the stirring cup is closed for stirring;

    when the control handle is located at a third position, the sealant of the cam stops blocking the air inlet of the vacuum cover, and the movable valve keeps closing the stirring cup air hole, such that the vacuum cover is in a non-vacuum state enabling removal of the same, while the stirring cup, still in a vacuum state, is taken down from the vacuum juicer.
