    • A water purifier including a body section, a cartridge section for purifying water, and a spool section. A horizontal water passage which is provided in the main body constituting the body section has a large-diameter portion opened to the outside of the main body and a small-diameter portion connected to the cartridge section. A vertical water passage is provided in the main body in communication with the large-diameter portion and therein a spool sleeve is disposed. A spool body including an "O" ring is provided such as to change the direction of flow of the horizontal water passage by selectively coming into contact with the continuous portion leading from the large-diameter portion to the small-diameter portion and the spool sleeve without making any contact with the edges which communicate the vertical water passage with the large-diameter portion, thereby avoiding the impairment of the "O" ring and lengthening the life of the water purifier.
    • 一种净水器,包括主体部分,用于净化水的盒部分和卷轴部分。 设置在构成主体部分的主体中的水平水通道具有向主体外侧开口的大直径部分和连接到盒部分的小直径部分。 在主体中设置有与大直径部连通的垂直水通道,并且设置有卷筒套筒。 设置有包括“O”形环的卷筒体,以便通过选择性地与从大直径部分到小直径部分的连续部分接触而改变水平水道的流动方向,并且卷轴套 而不会与垂直水通道与大直径部分连通的边缘接触,从而避免了“O”形环的损伤并延长了净水器的使用寿命。
