[0025] Please refer to Figures 1 to 7 , which is a schematic view of the double-control handle faucet 100 for a washbasin of the present utility model. The double-control handle faucet 100 for a washbasin includes a water outlet assembly 20 and two groups of control valve assemblies 30 communicated with the water outlet assembly 20. The water outlet assembly 20 includes a zinc alloy outer shell tube 21, a plastic inner tube 22 installed inside the zinc alloy outer shell tube 21, and a three-way joint 23 connected to the zinc alloy outer shell tube 21 and communicated with the plastic inner tube 22. The control valve assembly 30 includes an inner body tube 31, a control valve core 32 and a zinc alloy control handle 33 which are installed at the upper end of the inner body tube 31 and are connected to each other, a plastic water outlet pipe 34 and a water inlet pipe 35 with one end connected to the lower end of the inner body tube 31 and communicated with the control valve core 32. The other end of the plastic water outlet pipe 34 is communicated with the three-way joint 23. Wherein, the water inlet pipe 35 in this embodiment is a copper pipe, so that the rigidity during installation is sufficient and the stability is strong.

[0026] Further, a bubbler 24 is installed at one end of the zinc alloy outer shell tube 21, and the bubbler 24 is communicated with one end of the plastic inner tube 22 far away from the three-way joint 23. The bubbler 24 is preferably a constant flow bubbler, so that the flow rate of the flowing water is stable and the experience is good.

[0027] Further, the water outlet assembly 20 further includes a foot valve tube 25, a water outlet base 26 sleeved on the foot valve tube 25, and a water outlet face cover 27 threadedly connected to the outer wall of the foot valve tube 25. The bottom end of the water outlet face cover 27 is connected to the water outlet base 26, and the top end of the water outlet face cover 27 is connected to the zinc alloy outer shell tube 21. Through the settings of the water outlet face cover 27 and the water outlet base 26, the zinc alloy outer shell tube 21, the water outlet face cover 27 and the water outlet base 26 can be quickly disassembled or assembled with the foot valve tube 25, which is very practical.

[0028] Further, the water outlet assembly 20 further includes a positioning sleeve 28. The two ends of the positioning sleeve 28 are respectively connected to the foot valve tube 25 and the three-way joint 23. One end of the plastic inner tube 22 passes through the positioning sleeve 28 and is communicated with the three-way joint 23. Through the setting of the positioning sleeve 28, the end of the plastic inner tube 22 communicated with the three-way joint 23 can be ensured to be stable and reliable.

[0029] Further, the control valve assembly 30 further includes a handle base 36 sleeved on the inner body tube 31 and a handle cover 37 threadedly connected to the outer wall of the inner body tube 31. The bottom end of the handle cover 37 abuts against the handle base 36, and the top end of the handle cover 37 abuts against the zinc alloy control handle 33. In this way, when in use, the zinc alloy control handle 33 can rotate a certain angle relative to the handle cover 37, thereby driving the control valve core 32 to adjust the opening and closing state and the size of the opening and closing port, so as to ensure that the water flowing in through the water inlet pipe 35 can enter the three-way joint 23 through the plastic water outlet pipe 34 and finally flow out through the plastic inner tube 22.

[0030] In this embodiment, there are two groups of control valve assemblies 30, so that one group can be used to control the cold water inlet and the other group can be used to control the hot water inlet. During specific use, the two groups can adjust the inflow rate and mix at the three-way joint 23, so as to adjust the water temperature flowing out through the plastic inner tube 22.

[0031] Further, a valve core pressing cover 38 is installed at the top of the control valve core 32, and the valve core pressing cover 38 abuts against the inner wall of the zinc alloy control handle 33, so that the connection and disassembly of the zinc alloy control handle 33 and the control valve core 32 are convenient.

[0032] Further, the basin double-control handle faucet 100 further includes a pull rod 40 that passes through the zinc alloy outer shell tube 21 from top to bottom, and a quick-connect row rod 41 that is movably connected to the bottom end of the pull rod 40. Through the quick-connect row rod 41, the water storage and drainage of the basin can be well controlled, and it is more suitable for various usage situations. Further still, the basin double-control handle faucet 100 further includes a first transmission rod 42 and a second transmission rod 43 that are connected to each other. One end of the first transmission rod 42 away from the second transmission rod 43 is movably connected to the quick-connect row rod 41, and one end of the second transmission rod 43 away from the first transmission rod 42 is connected to the pull rod 40. In this way, when in use, the pull rod 40 can achieve transmission drive through the first transmission rod 42 and the second transmission rod 43, improving the convenience of operation. To ensure that the pull rod 40 is not easy to slip off when pulled by hand, a lifting head 44 is installed on the top end of the pull rod 40.

[0033] For the above-mentioned basin double-control handle faucet 100, since the zinc alloy outer shell tube 21 and the zinc alloy control handle 33 are used, it is possible to avoid using expensive copper materials, resulting in a low manufacturing cost. Zinc alloy does not contain lead elements, so there is no safety hazard during use, and the safety is higher. It adopts a combination of a plastic inner tube 22 and a zinc alloy outer shell tube 21. The plastic inner tube 22 is in direct contact with water, and the plastic inner tube 22 does not contain lead elements, further improving the environmental protection and safety. The control valve core 32 and the three-way joint 23 are connected through the plastic water outlet pipe 34, so that the bending operation is easy during installation, the installation and use are convenient, and the practicability is strong.
