  The switching cock 50 disclosed in Patent Document 1 can switch between the water discharge flow path S and the branch flow path P by operating the switching lever 52 and switching the arrangement of the partition wall 58 of the valve body 53. However, the partition wall 58 provided in the valve body 53 has a specific configuration having a predetermined inclination, and the valve body 53 has a hollow structure, so that the structure of the valve body 53 itself is complicated. Further, since the valve body 53 is switched using the switching lever 52, the structure of the cock body 51 corresponding to the valve body 53 and the structure of the entire switching cock 50 are also complicated. Further, since the hollow valve body 53 is rotated, there is a problem in the durability of the valve body 53. In addition, since the cock body 51 and the valve body 53 have a complicated structure as shown in FIG. 14, the switching cock 50 has narrow openings 61, 62, 63 connecting the cock body 51 and the valve body 53, The required amount of water distribution may not be obtained.

  Furthermore, in the switching cock disclosed in Patent Document 2, a plurality of grooves 78, 79, 80 are formed on the outer periphery of the switching valve 73 to form a flow path, and the grooves and the switching valve 73 are fitted. Water is distributed through a flow passage formed between the main body 70 and the main body 70. Therefore, in this switching cock, the accuracy of fitting between the grooves 78, 79, 80 and the main body 70 is important, and if a deviation occurs, it may cause water leakage or the like.

The second flow outlet 11 ′ of the switching means 2 ′, the opening 28d of the valve seat packing 28, the second opening 15 of the support 13 ′, and the lower communication port 23 of the exterior body 17 ′. Water is distributed from the water distribution port 24 ′ through the water distribution channel 19 ′ of the exterior body 17 ′.

  In the case of use example 5, raw water flows from the first injection path 18A of the switching cock 1A, but the first outlet 9 of the switching means 2 'communicates with the water distribution path 19' of the exterior body 17 '. The raw water is never distributed.

  By adopting the structure as described above, according to the switching cock 1A of the second embodiment, the switching cock of the present invention can be applied to a so-called faucet integrated water purifier or the like in which different types of liquid are poured simultaneously from the same direction. Can be used. That is, switching of each flow path can be performed by operating only the switching means provided in this switching cock. Furthermore, in order to form each flow path, other parts such as grooves, partition plates, etc. Since it is not necessary to provide a simple structure, the structure of the switching means can be simplified. Therefore, by using this switching means, a switching cock having a simple structure with a small number of parts can be connected to a faucet integrated water purifier or the like.

  Further, in the switching cock according to the second embodiment, the stepped portion of the second cylindrical body is structured so as to be connected to an external water pipe or the like. Therefore, the external cock is not limited to a faucet integrated water purifier or the like. A highly versatile switching cock that can be connected to a water injection device can be provided.

  Moreover, in the switching cock of Embodiment 2, although the water flow pipe as an attachment means was used for the 2nd injection path, you may provide a 2nd injection path not only in this but in the switching cock itself. At that time, a pipe or the like provided with connecting means may be provided on the exterior body of the switching cock.

  Moreover, in the switching cock of Embodiment 1 or 2, you may make it stop water by arrange | positioning a switching means in the position where each flow path is not connected. By setting it as such a structure, it can carry out by operating the switching cock at hand, without operating water distribution and water stop with a faucet etc.
