New-type water-saving tank

The utility model discloses a novel water-saving tank which comprises a water-saving fitting part, a closestool water tank connected with or separated from a closestool bowl and a higher water tank and a lower water tank of a squatting pan, wherein, each water tank is provided with a stool flushing turntable lifting stem device, a pee flushing turntable lifting stem device, a draw-off valve and a high draw-off valve component communicated with a draw-off valve pipe. When a user turns a stool flushing turntable, a stool flushing lifting stem can turn on the draw-off valve for stool flushing with greater water volume; when the user turns a pee flushing turntable, a pee flushing lifting stem can turn on a high draw-off valve for pee flushing with less water volume; therefore, the utility model saves a great amount of water and reduces blowdown load.
