[0048] When the user needs to switch to the upward second water outlet 122 for gargling, the knob cover 7 is rotated, and the knob cover 7 drives the knob 6 to rotate, and the protrusion 35 slides the sliding section close to the positioning section at one end of the water sealing component 2, and reaches the positioning section far away from the water sealing component 2 to be positioned, and the first water outlet 32 ​​is exposed outside the small opening 72; at the same time, the connecting hole 33 pulls the limit head 221 to move toward one end of the knob 6, and the pull rod 22 moves forward accordingly, and the sealing ring 21 leaves the first flow port 132 and blocks the second flow port 112, and the water flows from the third flow chamber 131 through the first flow port 132, through the first flow chamber 111, the water inlet, and the water chamber 31, and flows out from the first water outlet 32 ​​for user use. The knob cover 7 is rotated in the reverse direction, that is, the knob 6 is rotated in the reverse direction, so that the protrusion 35 moves to the end of the positioning section close to the water sealing component 2, thereby returning to the default water outlet mode.

[0049] The present invention provides a knob 6 at one end of the upper water outlet 3, and the knob 6 is rotated to operate so that the first water outlet 32 ​​of the upper water outlet 3 can protrude or retract inside or outside the knob 6, so that the user will not touch the first water outlet 32 ​​when switching the water outlet, and when the first water outlet 32 ​​is not needed, the first water outlet 32 ​​can be retracted into the knob 6 to ensure that the first water outlet 32 ​​is not exposed. The structure is simple, the operation is convenient, and the manufacturing is convenient. The protrusion 35 is provided on the upper water outlet 3, and the sliding rail 63 is provided on the knob 6, and the sliding rail The central axis of the knob 6 is tilted around the ring 63, so that when the protrusion 35 slides in the sliding rail 63, it is converted from circumferential rotation to linear movement, so that the first water outlet 32 ​​can be extended and retracted inside and outside the knob 6, which is convenient for the user to extend it when he needs to rinse his mouth, and retract it when he does not need to rinse his mouth; a spring 26 is arranged on the water sealing component 2 to prevent the first flow port 132 from being opened and causing water to flow out of the first water outlet 32 ​​when the upper water outlet part 3 has not yet extended out of the knob 6, thereby ensuring that water can only flow out from the first water outlet 32 ​​or the second water outlet 122 at a time.
