When the button 41 is released, the first water passage 211 and the second water passage 213 remain in a connected state. At this time, water flows through the second water passage 213, the first water passage 211, the first water passage 21A, the second cavity 24, the second water passage 21B in sequence, then enters the first cavity 23, and then flows out from the first water outlet 2211 along an angle of 70-78° with the horizontal direction through the first water outlet passage 221, forming a smooth water column, which is convenient for rinsing the mouth. When the button 41 is pressed away from the other end of the blocking member 43, the button 41 reversely rotates relative to the main body 21, drives the blocking member 43 to move reversely, the blocking part 434 blocks the water distribution port 4213, the water inlet hole 253 and the water outlet hole 254 of the first valve cavity 25 are connected, thereby connecting the second water passage 213 and the second water outlet passage 212, blocking the first water passage 211, and the spring deformation recovers. Water flows through the second water passage 213, the water inlet hole 253 of the first valve cavity 25 in sequence, enters the second water outlet passage 212 through the water outlet hole 254 of the first valve cavity 25, and the operation of the bubbler can control the water flow. Or the water inlet end of the second water passage 213 is closed, the water flow back pressure acting on the blocking part 434 is released, the spring deformation recovers, drives the blocking member 43 to move reversely, and drives the button 41 to reset. For the use of the second switching unit 5, since other prior art documents have detailed description, it is not repeated here.
