The valve core 22 is a mixing valve core. The valve core 22 connects hot water and cold water to form mixed water. The valve core 22 can control the mixing ratio of hot water and cold water to adjust the temperature of the mixed water.

[0033] The valve assembly 2 also includes a valve seat cover 24, a valve core cover 25 and a decorative semicircular cover 26. When the valve seat 21 is installed on the fixed part 11, the valve seat cover 24 is screwed to the top of the fixed part 11 and pressed against to fix the valve seat 21. When the valve core 22 is installed on the valve seat 21, the valve core cover 25 is screwed to the top of the fixed part 11 and pressed against to fix the valve core 22. The valve core cover 25 extends a certain distance from the top of the fixed part 11, and the decorative semicircular cover 26 is screwed to the valve core cover 25.

[0034] The valve seat 21 includes a water outlet 211 arranged downward, and the water outlet device 100 includes an adapter seat 4 connected to the water outlet 211. The adapter seat 4 is extended with a switching water circuit, and the switching water circuit includes a water flow channel 41, a first water outlet channel 42 and a second water outlet channel 43 extending in the adapter seat 4. The water flow channel 41 is connected to the water outlet 211, and the water flow channel 41 and the water outlet channel are respectively connected to the second water outlet channel 43. The water outlet device 100 also includes a first water outlet component 51 and a second water outlet component 61. The first water outlet component 51 is connected to the first water outlet channel 42, and the second water outlet component 61 is connected to the second water outlet channel 43. In this embodiment, the first water outlet component 51 is a nozzle, and the second water outlet component 61 is a bubbler.

[0035] The adapter 4 includes an upwardly extending plug connector 45, into which the water passage 41 extends. The plug connector 45 is plugged into the water outlet 211. A first plug connector 46 is provided on the downward side of the adapter, which communicates with the first water outlet channel 42. A second plug connector 47 is provided on the side of the adapter near the water outlet 12, which communicates with the second water outlet channel 43. The water outlet device 100 also includes a first water outlet pipe assembly 52 and a second water outlet pipe assembly 62. One end of the first water outlet pipe assembly 52 is plugged into the first plug connector 46, and the other end extends through the threaded tube 131 and connects to the first water outlet member 51. One end of the second water outlet pipe assembly 62 is plugged into the second plug connector 47, and the other end extends into the water outlet 12 and connects to the second water outlet member 61. The second water outlet member 61 is provided at the end of the water outlet 12 and discharges water downward. When the adapter seat 4 is installed, the plug connector 45 of the adapter seat 4 is clamped on the valve seat 21 and the fixing portion 11 , and one side of the adapter seat 4 is embedded in the inner wall of the fixing portion 11 .

[0036] In the switching water path, the outlet end 411 of the water passage 41 is reduced in diameter and faces the water inlet end 421 of the first water outlet channel 42. When the water flowing through the water passage 41 passes through the outlet end 411 of the water passage 41, the water velocity increases due to the reduced diameter of the outlet end 411 of the water passage 41, and the water flows directly into the first water outlet channel 42. When the first water outlet member 51 is connected and opened, the water flows out of the first water outlet member 51. When the first water outlet member 51 is closed, the water can no longer flow into the first water outlet channel 42, and the water flows into the second water outlet member 61 from the second water outlet channel 43.

[0037] When the first water outlet part 51 is controlled to open again, because the direction of the water flow is the first water outlet channel 42 and the water flow is accelerated, the flow rate of the water flowing to the first water outlet channel 42 is greater than the flow rate of the water flowing to the second water outlet channel 43, the water flow, the first water outlet channel 42 produces a siphon effect, and the second water outlet channel 43 gradually stops water.

[0038] The water inlet end 421 of the first water outlet channel 42 also includes a water inlet seat 422 extending toward the water outlet end 411 of the water passage 41. The water outlet direction of the water passage 41 is toward the water inlet seat 422. The water inlet seat 422 is separated from the water outlet end 411 of the water passage 41 and defines a connecting gap 44 connecting to the second water outlet channel 43.

[0039] The water inlet seat 422 extends into the second water outlet channel 43. This shortens the distance between the outlet end 411 of the water passage 41 and the first water outlet channel 42, further enhancing the siphon effect. The connecting gap 44 has a smaller water flow area, further reducing the flow rate of water into the second water outlet channel 43. During installation, the water inlet seat 422 is embedded in the first plug port 46. The first outlet pipe assembly 52 is connected to the first plug port 46 and presses against the water inlet seat 422 to secure it.

[0040] The inner diameter of the outlet end 411 of the water passage 41 is smaller than the inner diameter of the water inlet end 421 of the first water outlet channel 42. This increases the water flow area between the water passage 41 and the first water outlet channel 42. The water pressure outside the connecting gap 44 is greater than the water pressure inside, increasing the siphon effect and drawing water from the outside to the inside of the connecting gap 44. In this embodiment, the inner diameter of the outlet end 411 of the water passage 41 is smaller than the inner diameter of the water inlet seat 422. In this embodiment, the outlet end 411 of the water passage 41 is located above the water inlet end 421 of the first water outlet channel 42. This accelerates the water flow under the action of gravity, resulting in a faster flow rate.

[0041] The water outlet end 411 of the water passage 41 includes a first water outlet section 4111 and a second water outlet section 4112 connected in sequence along the water outlet direction. The inner diameter of the first water outlet section 4111 gradually decreases along the water outlet direction, and the second water outlet section 4112 is toward the water inlet end 421 of the first water outlet channel 42. The water flow is accelerated through the first water outlet section 4111 and radially guided to the first water outlet channel 42 through the second water outlet section 4112.

[0042] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
