     In the kitchen, water from different sources is usually required for different purposes like washing or drinking. In order to reduce the number of faucets installed in the kitchen, and enhance the utilization of the kitchen space, a faucet has been developed for connection to dual water sources. 
     Said faucet that can be connected to dual water sources includes a main body, two valve cores, a flow guide component, a water pipe and a water outlet, wherein each valve core and the flow guide component is respectively arranged inside the main body, the water outlet is configured on the water outlet end of the main body, and the water outlet is configured with two water outlet structures. Each valve core is respectively communicated to different water sources through a pipe, and each valve core respectively controls the flow of water from each water source into the flow guide component. One end of the water pipe is connected to the flow guide component. The water pipe passes through the inside of the main body and extended to the water outlet. The water pipe includes an outer pipe and an inner pipe. The inner pipe is arranged inside the outer pipe. The outer pipe and the inner pipe are respectively communicated to each water outlet structure. The flow guide component is used to guide the water flow from each valve core to respectively go into the outer pipe and the inner pipe, so that water from each water source can respectively pass through the outer pipe and the inner pipe, and flow out from each water outlet structure. Furthermore, as needed, the water outlet can be disassembled from the main body. In this case, the water outlet pulls the flexible water pipe to move along with the water outlet, so that the water outlet can be put close to the object to be washed or the water container to avoid splash of water and enhance convenience. 
     The construction of the flow guide component is complicated, and the assembly between the flow guide component and the main body is not easy.

     DETAILED DESCRIPTION OF THE INVENTION 
     Depicted in  FIG.  1    through  FIG.  8    is a preferred embodiment of the fast assembling faucet component for dual water sources according to the invention, which includes a main body  10 , a socket  20 , a positioning member  30  and a water pipe  40 . The main body  10  includes a base  50  and an extending pipe  60 , wherein the top end of the base  50  is connected to one end of the extending pipe  60 , the other end of the extending pipe  60  is separably connected to a water outlet  12 . The two sides of the base  50  are respectively formed with a first valve chamber  51  and a second valve chamber  52 , so that the first valve  14  is configured in the first valve chamber  51 , the second valve  16  is configured in the second valve chamber  52 . The inside of the base  50  is formed with a first chamber  53 , a second chamber  54 , a third chamber  55  and a connecting channel  56 . The first chamber  53  is extended to the bottom of the base  50  and is communicated to the outside. The second chamber  54  extends upward through the first chamber  53 . The third chamber  55  extends upward through the second chamber  54 . The connecting channel  56  is communicated to the first chamber  53  and the extending pipe  60 . The sectional area of the connecting channel  56  in the horizontal direction is smaller than the first chamber  53 . A first flow channel  57  is communicated to the first valve chamber  51  and the second chamber  54 . A second flow channel  58  is communicated to the second valve chamber  52  and the third chamber  55 , so that the first valve  14  can control water to pass through the first flow channel  57  and go into the second chamber  54 . The second valve  16  controls water to pass through the second flow channel  58  and go into the third chamber  55 . 
     The socket  20  is configured in the first chamber  53 , and the socket  20  is formed with a first passageway  21  and a second passageway  23  along the axial direction. The first passageway  21  and the second passageway  23  are respectively extended to the top end and bottom end of the socket  20 . The inner edge of the first passageway  21  is formed with a convex part  22  along the radial direction. The second passageway  23  is communicated to the connecting channel  56 . The socket  20  crosses the two first inlet channels  24  and a second inlet channel  25 , so that the water from the first water source (not shown in the figure) is transmitted by the two first pipes  91  to pass through each first inlet channel  24  and go into the first valve chamber  51 , and the water from the second water source (not shown in the figure) is transmitted by the second pipe  92  to pass through the second inlet channel  25  and go into the second valve chamber  52 . Under the control of the first valve  14  and the second valve  16 , the water respectively flows to the second chamber  54  and the third chamber  55 . In the case that the first valve  14  is a cold and hot water mixing valve, there are respectively two first inlet channels  24  and two first pipes  91 . Based on the options and exchanges of the first valve  14  and the second valve  16 , the numbers of the first inlet channels  24 , the second inlet channels  25 , the first pipes  91  and the second pipes  92  can be changed accordingly, and are not limited to the example provided in the preferred embodiment. However, the number of the first inlet channel  24 , the second inlet channel  25 , the first pipe  91  and the second pipe  92  must be at least one. 
     As needed, the first passageway  21  can be extended laterally to one side of the socket  20 , in the form of a lateral opening, so as to form another embodiment not shown in the drawings. Said another embodiment is a variation based on the preferred embodiment. 
     The positioning member  30  is connected to the base  50 , so as to position the socket  20 , and limit the axial displacement of the socket  20 . 
     The water pipe  40  passes through the second passageway  23  and the connecting channel  56  and goes into the extending pipe  60  to be connected to the water outlet  12 . The water pipe  40  includes an outer pipe  42 , an inner pipe  44  and a water inlet structure  70 , wherein the inner pipe  44  is configured inside the outer pipe  42 , the outer pipe  42  and the inner pipe  44  is respectively communicated to the water inlet structure  70 . The water inlet structure  70  is formed with a convex ring  71  extending outward in the radial direction. The water inlet structure  70  is configured on the first passageway  21  in the axial direction. The convex part  22  is located below the convex ring  71 , so as to relatively limit the water inlet structure  70 . Thus, water from the first water source passes through the second chamber  54 , the water inlet structure  70 , and go into the outer pipe  42 , water from the second water source passes through the third chamber  55 , the water inlet structure  70 , and go into the inner pipe  44 . The outer pipe  42  is further sheathed with a protecting jacket  46 . The protecting jacket  46  is an optional component, used to protect the outer pipe  42 , avoiding damage of the outer pipe  42  during the configuration due to abrasion. 
     Below is a description of the operation of assembling the water pipe  40  to the main body  10 . As shown in  FIG.  9   , the end of the water pipe  40  away from the water inlet structure  70  extends from above the socket  20  into the first passageway  21  till the water inlet structure  70  and enters into the first passageway  21 . The convex part  22  is located below the convex ring  71 , limiting the water inlet structure  70  in the axial direction. In this way, the water inlet structure  70  and the socket  20  are combined. Then, as shown in  FIG.  10   , the socket  20  configured on the water inlet structure  70  extends from below the base  50  and enters into the first chamber  53 , and the water inlet structure  70  enters into the second chamber  54  and the third chamber  55 , and the second passageway  23  is communicated to the connecting channel  56 . Then, as shown in  FIG.  11   , the positioning member  30  is configured on the base  50 . The positioning member  30  is used to limit the socket  20  in the axial direction. Then, as shown in  FIG.  12   , after the water guiding member  40  is bent, the other end of the water guiding member  40  away from the water inlet structure  70  goes into the base  50  from below, and passes through the second passageway  23  and the connecting channel  56  and goes into the extending pipe  60  to be connected to the water outlet  12 . By now, the operation of assembling the water pipe  40  to the main body  10  is completed. During the process of extending the water guiding member  40  through the first passageway  21 , the second passageway  23 , the connecting channel  56  and the extending pipe  60 , the protecting jacket  46  can prevent the outer pipe  42  from contacting and scratching the components of the socket  20 , the base  50  and the extending pipe  60 .

The top end of the second water inlet pipe  76  is formed with a second water inlet  73  communicated to the third chamber  55 , so that water can pass through the second water inlet pipe  76  and go into the inner pipe  44 . 
     The water inlet structure  70  further includes a liner tube  77 . The liner tube  77  is configured between the first water inlet pipe  75  and the second water inlet pipe  76 , so as to maintain the relative construction of the first water inlet pipe  75  and the second water inlet pipe  76 . The liner tube  77  extends into the third chamber  55 , and the liner tube  77  is communicated to the third chamber  55  and the second water inlet pipe  76 . The seal ring  74  is optionally sheathed on the liner tube  77 . 
     The liner tube  77  is in threaded connection with the second water inlet pipe  76 . The periphery of the liner tube  77  is radially formed with a pressing part  772 . The pressing part  772  presses the top end of the first water inlet pipe  75 . The water inlet structure  70  further includes a locking member  78 . The locking member  78  presses the top end of the pressing part  772 , and the locking member  78  is in threaded connection with the first water inlet pipe  75 , so as to lock the liner tube  77 . 
     The positioning member  30  is a ring-shaped body, and the positioning member  30  goes into the first chamber  53  to push the socket  20 , so as to position the socket  20 . The water pipe  40  passes through the positioning member  30  and goes into the second passageway  23 . The positioning member  30  has a screw ring  32 . The screw ring  32  is screwed into the first chamber  53 , and the screw ring  32  pushes the socket  20 .
