When the object is in a position relatively close to the water outlet end 100, the distance sensor 250 controls the distal controller 230 to be turned off and the proximal controller 240 to be turned on.

The water flow self-adaptive regulation sensing faucet according to the embodiment of the utility model has the advantages that the distance between a limb or an object and the water outlet end 100 is sensed through the distance sensor 250, when the object is positioned at a position relatively far away from the water outlet end 100, the distance sensor 250 controls the close end controller 240 to be disconnected and the far end controller 230 to be conducted, at the moment, the far end water outlet pipeline 210 is conducted, the water flow of the water outlet end 100 is smaller, so that the object is impacted at a higher distance and does not have a larger sputtering range, the splashing phenomenon is not caused, and when a user needs a larger water flow, the object is close to the water outlet end 100, the distance sensor 250 controls the close end controller 230 to be disconnected and the near end controller 240 to be conducted, at the moment, the near end water outlet pipeline 220 is conducted, and the water flow of the water outlet end 100 is larger, so that the requirement of the user can be met.

Referring to fig. 3, specifically, the constant-current device includes a valve body 310, an inlet 311 and an outlet 312 formed on the valve body 310, a first current-limiting plate 320 and a second current-limiting plate 330 are sequentially disposed in the valve body 310 along the water flow direction, the second current-limiting plate 330 is fixedly connected in the valve body 310, the first current-limiting plate 320 is movably connected in the valve body 310, a water outlet 321 is formed in the first current-limiting plate 320, a current-limiting post 331 is disposed on the second current-limiting plate corresponding to the water outlet 321, the end of the current-limiting post 331 facing the water outlet 321 is in a cone structure, and a plurality of water draining holes 332 are circumferentially and circumferentially disposed on the current-limiting post 331. By arranging the constant flow device, when the water pressure in the valve body 310 becomes high, the first flow limiting piece 320 is tightly attached to the inner wall of the valve body 310 and moves towards the second flow limiting piece 330 under the action of high water pressure, the water outlet 321 is close to the flow limiting column 331, so that the water outlet area is reduced, the flow is controlled, when the water pressure is reduced, the first flow limiting piece 320 moves back due to the reduction of the water pressure, so that the water outlet area is increased, the flow is increased, the water outlet can be effectively controlled, and the reasonable water outlet can be obtained no matter in a high water pressure state or a low water pressure state. The water outlet 321 is preferably arranged at the central position of the first current limiting piece 320, and when the first current limiting piece 320 moves, the water outlet 321 at the central position can lead the whole first current limiting piece 320 to be pressed and balanced so as not to incline, thereby leading the movement to be more smooth and improving the sensitivity of water flow control.
