Referring to fig. 14, 16 to 17, the pipe connector 600 includes a first pipe connector 600a and a second pipe connector 600b, the first pipe connector 600a extends toward a side away from the bracket in the axial direction of the housing 10, the second pipe connector 600b extends toward the bracket in the axial direction of the housing 10, the first pipe connector 600a is connected to the inlet pipe 302 of the tap water pipe 30 and the inlet pipe 402 of the purified water pipe 40, respectively, and the second pipe connector 600b is connected to the outlet pipe 304 of the tap water pipe 30 and the second pipe 400 of the purified water pipe 40, wherein the outlet pipe 304 is connected to the first pipe 300. The pipe body connector 600 is generally threadedly engaged with each water supply pipe.

The second tube 400 is configured to be pivotable about the housing 10 with the stand. Specifically, the second tube 400 may be configured as an elastic member to satisfy a requirement of elongation in a distance when the second tube 400 is most pivoted about the housing 10 as the stand is pivoted, and a requirement of friction with the inner wall of the housing 10 without excessive bending of the second tube 400 itself when the second tube 400 is returned to the starting point as the stand is returned.

Alternatively, as shown in fig. 5 to 6, the second tube 400 may be configured to perform a drawing action with respect to the body 60, which is similar to a piston motion. When the second tube 400 is at the origin of rotation (the stent is not rotated relative to the housing 10), the second tube 400 is partially received in the body 60, and when the second tube 400 is at the end of rotation (the stent is rotated to the maximum angle relative to the housing 10), a portion of the second tube 400 received in the body 60 can be withdrawn from the body 60, and when the stent is rotated back to the origin of rotation again, the portion of the second tube 400 withdrawn from the body 60 is again retracted into the body 60. In this process, a good seal is maintained between the second pipe body 400 and the pipe body connector 600 of the body 60 to prevent leakage that may occur.

Specifically, after the flange 203 is inserted into the housing 10, the projection 203a rotates with the flange 203 of the bracket relative to the housing 10 until the projection 203a abuts against the boss 106 of the housing 10, and the rotation of the bracket relative to the housing 10 stops, at which time the bracket just starts to rotate 180 ° relative to the housing 10 from the rotation start point to the rotation end point. Of course, it will be understood by those skilled in the art that this angle is merely exemplary and is not intended to limit the present invention.

Preferably, as shown in fig. 11, the faucet 1 further includes a wear sleeve 70, the wear sleeve 70 being located between the flange 203 and the housing 10. The wear-resistant sleeve 70 is sleeved on the periphery of the flange 203 and has a radially extending periphery, and after the flange 203 sleeved with the wear-resistant sleeve 70 is inserted into the casing 10, the periphery abuts against the top edge of the casing 10 to prevent the wear-resistant sleeve 70 from falling into the casing 10. The circumference of the wear sleeve 70 is provided with a protrusion 700 and the housing 10 is provided with a groove 108 at the end of the engagement bracket, the protrusion 700 engaging the groove 108 to limit rotation of the wear sleeve 70 relative to the housing 10. The protrusion 700 may be a ridge, a rib, or a bump. In the embodiment shown in fig. 11, the protrusions 700 may be two, and when the wear sleeve 70 is mated with the housing 10, the two protrusions 700 respectively abut against the inner wall of the groove 108 to limit the rotation of the wear sleeve 70 relative to the housing 10, and during the relative rotation of the two, the rotation friction mainly occurs between the wear sleeve 70 and the housing 10, avoiding the wear of the bracket.

In addition, the valve core 802 of the faucet 1 for opening and closing tap water and purified water, respectively, includes a valve housing, a valve seat, a valve rod, a movable valve plate, a stationary valve plate, a rotary seat, and the like. Wherein, the rotary seat is arranged in the valve shell and is sequentially overlapped with a linkage piece, a movable valve plate and a static valve plate below the rotary seat. The valve housing engages the valve seat 800. The valve rod extends out of the valve shell from the rotary seat and is controllably connected to the rotary seat, and a linkage piece can be installed below the rotary seat and can drive the linkage valve plate along with the valve rod. The valve plate comprises a dynamic valve plate and a static valve plate, the dynamic valve plate comprises a mixing chamber and a flow guide groove, the flow guide groove can be communicated with the opening to guide pure water, and the static valve plate comprises a first guide hole and a second guide hole which are used for guiding cold water and hot water respectively, a tap water guide hole for guiding mixed water out and a pure water guide hole for guiding pure water out; the valve rod can rotate relative to the rotating seat, the linkage connecting piece further drives the movable valve plate to translate or rotate relative to the static valve plate, during the movement of the movable valve plate relative to the static valve plate, when the first introduction hole and/or the second introduction hole are/is communicated with the mixing chamber, tap water is started, and when the guide groove is communicated with the fluid through hole, purified water is started.
