[0023] The switching mechanism 2 includes a valve shaft 21, an inner valve shaft 22, a control button 23 and a reset spring 24. The water inlet channel 11, the first water outlet channel 12 and the second water outlet channel 13 form an intersection inside the body 1, and the valve shaft 21 is movably arranged at the intersection. The valve shaft 21 forms an internal valve cavity 211, and the inner valve shaft 22 is at least partially movably arranged in the internal valve cavity 211. The inner valve shaft 22 is at least partially movably arranged in the internal valve cavity 211. In this embodiment, the axis of the inner valve shaft 22 coincides with that of the valve shaft 21, and one end of the inner valve shaft 22 is located in the internal valve cavity 211, and the other end of the inner valve shaft 22 is located outside the internal valve cavity 211, and a telescopic connection can be achieved between the inner valve shaft 22 and the valve shaft 21.

[0024] The valve shaft 21 is movably arranged to be able to move between a first position connecting the water inlet channel 11 and the first water outlet channel 12 and a second position connecting the water inlet channel 11 and the second water outlet channel 13. In this embodiment, the valve shaft 21 is switched by blocking the entrance of the first water outlet channel 12 and blocking the entrance of the second water outlet channel 13. The internal valve cavity 211 is in communication with the second water outlet channel 13. The inner valve shaft 22 includes a close pushing position and a far pulling position that move relative to the valve shaft 21, the control button 23 links the inner valve shaft 22, and the return spring 24 is connected to the inner valve shaft 22; when the water outlet device is in the initial state, the valve shaft 21 is in the first position, and the inner valve shaft 22 is in the close pushing position, the control button 23 is pressurized to drive the inner valve shaft 22 to push the valve shaft 21 to move to the second position, the internal valve cavity 211 can pass water to overcome the elastic force of the return spring 24 under the action of water pressure to drive the inner valve shaft 22 to move to the far pulling position, the control button 23 can be pressurized to drive the inner valve shaft 22 to pull the valve shaft 21 to move to the first position, and the return spring 24 can push the inner valve shaft 22 to move to the close pushing position.

[0025] When in use, the water outlet device is in the initial state, the water inlet channel 11 is connected to the first water outlet channel 12, and when the water inlet channel 11 is flowing, the water flows into the water inlet channel 11 and passes through the intersection from the first water outlet channel 12, and is ejected from the first water outlet 31 to form bubble water. When the control button 23 is pressed for the first time, the control button 23 drives the inner valve shaft 22 and the valve shaft 21 to move to the second position. At this time, since the second water outlet channel 13 is flowing with water, the internal valve cavity 211 is also flowing with water synchronously. Under the action of water pressure, the inner valve shaft 22 is driven away from the valve shaft 21 to the pulling position. When the control button 23 is pressed again, the control button 23 can drive the inner valve shaft 22 to pull the valve shaft 21 to the first position. At this time, since the second water outlet channel 13 is no longer flowing with water, under the action of no water pressure, the reset spring 24 drives the inner valve shaft 22 to move to the near push position.

[0026] In this embodiment, the internal valve cavity 211 is connected to the second water outlet channel 13 via a through hole 212. The internal valve cavity 211 is provided with a plurality of through holes 212 along the circumference, and the number of the through holes 212 is 4 and they are arranged at the front end of the internal valve cavity 211.

The valve shaft 21 is also connected to a spring 216, and the valve shaft 21 can be kept in the second position under the action of water pressure. When water is stopped, the spring 216 can keep the valve shaft 21 in the first position.
