A household elevator comprises an elevator shaft and a passenger box; the inner wall of the elevator shaft is cylindrical and matched with the cylindrical passenger box, bearing rods distributed along a spiral line are arranged on the inner wall of the elevator shaft, rolling bearings are arranged on the bearing rods, and a screw capable of rotating relative to the passenger box is arranged above or below the passenger box; the radius of the addendum circle of the screw is larger than the radius of the passenger box, so that helical teeth on the screw are in contact with the outer surfaces of the bearings, and helical lines of the screw are matched with helical lines arranged on the elevator shaft bearings, so that the helical teeth of the screw can be in contact with the multiple bearings simultaneously to obtain balanced supporting force; and the screw is driven by a motor or a manual rocker to rotate relative to the passenger box so as to drive the passenger box to move up and down.
