When the pull-out head is hung on the seat, the water inlet pipe and the seat are non-rotatably fitted; an arc piece is also extended from the end of the water inlet pipe. When the pull-out head, i.e., the main body, is in a vertical direction, since the height of the arc piece here is relatively high (that is, the place where the arc piece contacts the first moving shaft at this time), the water inlet pipe is not rotatably fitted with the seat body. When the first movable shaft is driven by the first spring to bounce off, the inlet water flow of the first water diversion chamber is conducted, and the first inlet is closed; when the pull-out head is rotated to a horizontal direction by the main body, since the water inlet pipe is limited by the rotation on the seat body, the first movable shaft is driven by the main body to rotate relative to the water inlet pipe. At this time, the height of the arc piece is alternated. At this time, the distance from the place where the arc piece contacts the first movable shaft to the axis becomes smaller (or minimum), and the first movable shaft is pressed down. Then, the first inlet water flow of the first water diversion chamber is conducted, the inlet is closed, and the first water outlet hole discharges water.

[0045] The inlet is connected to the second water diversion chamber, and a second movable shaft is fixedly installed on the second water diversion chamber. When the second movable shaft bounces up under the action of the second spring, the second inlet is connected, the third inlet is closed, and water flows out from the second water outlet; when the button is pressed to drive the second movable shaft downward, the third inlet is connected, the second inlet is closed, and water flows out from the third water outlet.
