The technology of the branching structure of the kitchen shower 83 is a common technology and will not be elaborated here.

[0074] In this embodiment, a screw hole 14 is further provided on the partition wall, and the central axis of the screw hole 14 is perpendicular to the lower surface of the main body 1; a locking assembly is fixed to the screw hole 14, and the locking assembly includes a locking screw 4, a locking nut (not shown) and a gasket (not shown); the locking screw 4 is inserted into the reserved installation hole of the sink, and the main body 1 is locked on the sink by the locking nut under the sink; the gasket is arranged between the locking nut and the sink to prevent water flowing from the top of the sink to the reserved installation hole from seeping into the bottom of the sink.

[0075] The working principle of the present invention is briefly described as follows:

[0076] The faucet installs the main body 1 on the reserved installation hole of the sink, and locks the faucet to the reserved installation hole through the locking assembly. The hot water inlet pipe 51 is connected to the hot water outlet of the domestic municipal water supply, the cold water inlet pipe 52 is connected to the cold water outlet of the domestic municipal water supply, the mixed water pipe 53 is connected to the second connection end 72, the clean water pipe 54 is connected to the water purification device 6, and the other end of the water purification device 6 is connected to the first connection end 71, and the third connection end 73 is connected to the water outlet pipe 84. At this time, the position points where the faucet needs to be connected by the user have all been connected.

[0077] The default state of the valve core 2 is closed, and the positioning pin 22 is positioned in the positioning hole 213 by the positioning spring 23, so that the movable valve plate 25 and the static valve plate 26 do not rotate relative to each other at will, which is the fourth water flow mode, refer to Fig.10 As shown; operate the handle 3 to rotate outward clockwise, the movable valve plate 25 and the static valve plate 26 form relative rotation, the positioning pin 22 shrinks from the positioning hole 213 to the accommodating hole 244, and the water groove 252 gradually increases the overlapping area with the mixed water hole 263. When the water groove 252 completely covers the mixed water hole 263 and the cold water hole 262, the cold water reaches the maximum water flow area, which is the third water flow method, refer to Fig. 9 As shown; continue to rotate the handle 3 outward clockwise, the water groove 252 gradually overlaps with the hot water hole 261 and gradually increases. When the hot water hole 261, the cold water hole 262 and the mixed water hole 263 all overlap with the water groove 252, the cold and hot water water flow areas reach the maximum at the same time, and the cold and hot water mixing ratio is the same, which is the second water flow method, refer to Figure 8As shown; continue to rotate the handle 3 outward clockwise, the overlapping area of ​​the water groove 252 and the cold water hole 262 gradually decreases, that is, the cold water flow area becomes smaller, and the overlapping area of ​​the hot water hole 261 and the water groove 252 does not decrease. Therefore, the hot water flow area is larger than the cold water flow area, and the water flow is gradually heated. When the water groove 252 only overlaps with the hot water hole 261 and the mixed water hole 263, only hot water can flow out, which is the first water flow method. The second limiting edge 2432 is limited by the first limiting platform 214 and cannot continue to rotate. Refer to Figure 7 As shown; in the above four water flow modes, the water flows from the mixed water pipe 53 to the second connecting end 72, and then flows to the outgoing water channel of the water pipe 84 and flows to the kitchen shower 83 for users to use.

[0078] When the handle 3 is in the closed state, i.e., the fourth water flow mode, it rotates inward counterclockwise, the movable valve plate 25 and the static valve plate 26 form a relative rotation, the positioning pin 22 shrinks from the positioning hole 213 to the accommodating hole 244, and the water flow groove 252 gradually increases the overlapping area with the clean water flow hole 264. When the water flow groove 252 completely covers the clean water flow hole 264 and the cold water flow hole 262, the water flow provided by cold water to the clean water reaches the maximum water flow area, which is the fifth water flow mode. The first limiting edge 2431 is limited by the second limiting platform 215 and can no longer continue to rotate. Fig.11 As shown, water flows from the water purification pipe 54 to the water purification device 6 and then flows through the first connecting end 71, and then flows to the inner water outlet channel of the water pipe 84 and flows to the kitchen shower 83 for user use.

[0079] The present invention sets double water inlet and double water outlet on the main body 1, and both water inlets pass through the valve core 2 and then flow out to the water outlet channel, one of which can be connected to the water purification device 6, and the other water is directly connected to the water outlet pipe 84 for users to use; no matter which water is used, it first passes through the valve core 2 and then flows out, and the valve core 2 bears the municipal water pressure to prevent the water purification device 6 from bursting, leaking and other hidden dangers; cold and hot water inlets, purified water, and mixed water are set on the valve core 2, and through the limit table and fixed The positioning pin 22 is used to limit the water outlet restrictions among the five water outlet modes of cold water, hot water, mixed water, purified water and closed, to prevent the movable valve plate 25 and the static valve plate 26 from forming an infinite rotation and making it difficult to control the water outlet; the water outlet pipe 84, the kitchen shower 83 and the three-way joint 7 are all provided with two channels to provide two water needs of purified water and mixed water; the water is collected to the water outlet pipe 84 through the three-way joint 7, which provides a visual appearance of water outlet, which is beautiful and practical.

[0080] The above description shows and describes the preferred embodiments of the present invention.
