That is, any connection method without displacement relationship and relative rotation relationship between the two, that is, including non-removable fixed connection, removably fixed connection, connected as a whole, and fixed connection through other devices or components.

[0034] In the claims, the description, and the drawings of the present disclosure, the terms “including”, “having”, and their variations are intended to mean “including but not limited to”.

[0035] Referring to FIGS. 1 to 5, a preferred embodiment of a pull-out faucet is provided. The pull-out faucet comprises a faucet body 18, a first water inlet passage 19, a second water inlet passage 11, a water-passing passage 12, a water-dividing seat 10, a pull-out flexible hose 20, a pull-out head 30, and a control valve 40.

[0036] Each of the first water inlet passage 19, the water-passing passage 12, and the control valve 40 is disposed in the faucet body 18, and each of the first water inlet passage 19 and the water-passing passage 12 is in communication with the control valve 40. Specifically, referring to FIG. 2, the faucet body 18 comprises a faucet housing 50, a valve seat 60, and a bent tube 70. The valve seat 60 is fixedly connected to the faucet housing 50, and the bent tube 70 is disposed on the faucet housing 50.

[0037] The pull-out flexible hose 20 is a tube-in-tube structure and comprises a first water outlet passage 21 and a second water outlet passage 22. Specifically, referring to FIG. 4, the pull-out flexible hose 20 further comprises an outer tube 23 and an inner tube 24 fixed in the outer tube 23. The second water outlet passage 22 is formed in the inner tube 24, and the first water outlet passage 21 is formed between the inner tube 24 and the outer tube 23. In an actual tube making process of the pull-out flexible hose 20, nylon wire can be wrapped around the outer tube 23 for improving support strength to ensure that the inner tube 24 will not burst due to high water pressure, and the outer tube 23 also has a function of anti-wear when the pull-out flexible hose 20 is pulled out.

[0038] Each of the water-passing passage 12, the second water inlet passage 11, and the pull-out flexible hose 20 is connected to the water-dividing seat 10 so that the first water outlet passage 21 is in communication with the water-passing passage 12 and the second water outlet passage 22 is in communication with the second water inlet passage 11. The pull-out head 30 is connected to a second end of the pull-out flexible hose 20, and the pull-out head 30 comprises a first water outlet 31 in communication with the first water outlet passage 21 and a second water outlet 32 in communication with the second water outlet passage 22. In this embodiment, the second end of the pull-out flexible hose 20 passes through the faucet housing 50 and the bent tube 70, then extends out of the bent tube 70, and is connected to the pull-out head 30. The first water inlet passage 19 comprises a cold water inlet passage 13 and a hot water inlet passage 14. Each of the cold water inlet passage 13, the hot water inlet passage 14, and the water-passing passage 12 is plugged into the valve seat 60, and the control valve 40 cooperates with the valve seat 60 to control an opening and a closing of the first water outlet passage 21 and a temperature of water that flows from the control valve 40. In this embodiment the control valve 40 cannot control an opening and a closing of the second water outlet passage 22. According to needs, in some embodiments, the control valve 40 can also have a function of switching at least one of the first water outlet passage 21 or the second water outlet passage 22 to be opened and closed, which is not limited thereto.

[0039] In this embodiment, the water-dividing seat 10 is substantially V-shaped, and the water-dividing seat 10 comprises a first water-dividing cavity 15, a second water-dividing cavity 16, and a converging cavity 17 respectively in communication with the first water-dividing cavity 15 and the second water-dividing cavity 16. The water-passing passage 12 is sealingly plugged into and matched with the first water-dividing cavity 15, and the second water inlet passage 11 is sealingly plugged into and matched with the second water-dividing cavity 16. A first end of the pull-out flexible hose 20 is sealingly plugged into and matched with the converging cavity 17. Referring to FIG. 4, an end of the inner tube 24 at the first end of the pull-out flexible hose 20 extends out of the outer tube 23 and is plugged into the second water-dividing cavity 16. A junction of the first water-dividing cavity 15 and the converging cavity 17 is in communication with a top end of the first water outlet passage 21.

[0040] In this embodiment, the pull-out faucet further comprises a sealing water-proof gasket 80. An outer periphery of the end of the inner tube 24 comprises an annular groove 241 in which the sealing water-proof gasket 80 is disposed, and the sealing water-proof gasket 80 sealingly abuts and is matched with a cavity wall of the second water-dividing cavity 16. The arrangement of the sealing water-proof gasket 80 can prevent the water in the water-passing passage 12 from flowing into the second water inlet passage 11 to avoid water mixing.

[0041] Moreover, one or more first one-way valves 151 are disposed in the first water-dividing cavity 15, and one or more second one-way valves 161 are disposed in the second water-dividing cavity 16. A flow restrictor 152 is also disposed in the first water-dividing cavity 15. Referring to FIG. 4, the one or more first one-way valves 151 are two first one-way valves 151 spaced apart from each other along an up-and-down (i.e., vertical) direction, and the flow restrictor 152 is located below the two first one-way valves 151. The one or more second one-way valves 161 are two second one-way valves 161 spaced apart from each other along the up-and-down direction.

[0042] In this embodiment, the second water inlet passage 11 comprises a solenoid valve 90 that can control an opening and a closing of the second water outlet passage 22. A water purifier 91 is also disposed on the second water inlet passage 11. As shown in FIG. 1, the water purifier 91 is located upstream of the solenoid valve 90.

[0043] When purified water supplied from the water purifier 91 needs to be used, it is only necessary to open the second water outlet passage 22 through the solenoid valve 90 to discharge the purified water. During use, a water outlet angle and a water outlet direction of the second water outlet 32 can be changed by pulling the pull-out head 30. When tap water needs to be used, it is only necessary to open the first water outlet passage 21 through the control valve 40 to discharge the tap water. During use, a water outlet angle and a water outlet direction of the first water outlet 31 can be changed by pulling the pull-out head 30. That is, the first water outlet passage 21 and the second water outlet passage 22 can not only be controlled independently, but also a pull-out function of the pull-out head 30 can be used to change the water outlet angles and the water outlet directions of the first water outlet 31 and the second water outlet 32, which is more convenient to use.

[0044] The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
