All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0030] Refer to Figures 1-7As shown in the figure, a manual and induction integrated faucet includes a faucet body 10, a valve core, a handle 20, a cold water inlet pipe 30, a hot water inlet pipe 40, a water outlet pipe 50, an induction unit and a control device. The valve core and the control device are both arranged inside the faucet body 10. The handle 20 is arranged on one side of the faucet body 10 and is connected to one end of the valve core. The other end of the valve core is connected to the control device. The induction unit is arranged on the faucet body 10 and is electrically connected to the control device. Both the cold water inlet pipe 30 and the hot water inlet pipe 40 are connected to one end of the water outlet pipe 50 through the valve core. The valve core includes a moving piece 5 and a static piece 6. The moving piece 5 is movably attached to the static piece 6. The static piece 6 has a cold water inlet hole 61, a hot water inlet hole 62, a first water outlet hole 63 and a second water outlet hole 64. The cold water inlet pipe 30 is communicated with the cold water inlet. The hot water inlet pipe 40 is communicated with the hot water inlet. The moving piece 5 has a water guide groove 51, a first water passing hole 52 and a second water passing hole 53. The first water passing hole 52 and the second water passing hole 53 are communicated through a water passing channel. When the moving piece 5 moves, the valve core has the following two water outlet modes: The first water outlet mode is that the first water passing hole 52 is communicated with the cold water inlet hole 61 and / or the hot water inlet hole 62, the second water passing hole 53 is communicated with the second water outlet hole 64, and the first water outlet hole 63 is not communicated with any water inlet hole. The second water outlet mode is that the first water outlet hole 63 is communicated with the cold water inlet hole 61 and / or the hot water inlet hole 62 through the water guide groove 51, the first water passing hole 52 is communicated with the cold water inlet hole 61 and / or the hot water inlet hole 62, and the second water passing hole 53 is communicated with the second water outlet hole 64.

[0031] During specific implementation, the control device includes an electromagnetic valve and a magnetic control sensor. The electromagnetic valve is arranged on the water outlet pipe 50 and is connected to the second water outlet hole 64 to control the allowing or blocking of the cold and hot mixed water from passing through the water outlet pipe 50. When the handle 20 is in the closed state, the cold and hot mixed water flows through the electromagnetic valve, and the electromagnetic valve controls the water outlet. A water flow detection device is arranged at the first water outlet hole 63. When the handle 20 is opened, the water flow detector can detect the water flow passing through, trigger the magnetic control sensor, and the main controller determines that the handle 20 is opened, and then controls the electromagnetic valve to close. The induction unit is an infrared induction unit / touch induction unit. The connection method and working principle of the infrared induction unit / touch induction unit and the electromagnetic valve are the same as those of the induction device and the electromagnetic valve of the traditional induction automatic faucet, and will not be repeated here. Whether the handle 20 is in the open or closed state, the cold and hot mixed water outlet is in a normally open state, and the water outlet is controlled by the electromagnetic valve. Whether the electromagnetic valve controls the water outlet or the water outlet is controlled by opening the handle 20, the cold and hot water outlet ratio can be adjusted by rotating the valve core to achieve the purpose of adjusting the water outlet temperature.

[0032] In the present invention, a handle disposed on one side of a faucet body is connected to one end of a valve core disposed inside the faucet body. The other end of the valve core is connected to a control device disposed inside the faucet body. An induction unit disposed on the faucet body is electrically connected to the control device. A cold water inlet pipe and a hot water inlet pipe are both connected to one end of a water outlet pipe through the valve core. By providing a water guide groove and a water passage on a moving piece of the valve core to respectively connect to a first water outlet hole and a second water outlet hole, the operation of this valve core is more convenient, its structure is simple and compact, and the user experience effect is improved.

[0033] Further, when the moving piece 5 moves, the valve core further has a third water outlet mode: the first water outlet hole 63 is not connected to any water inlet hole, and the second water outlet hole 64 is not connected to any water inlet hole.

[0034] During specific implementation, as Figure 3 shown, the first water outlet hole 63 is not connected to any water inlet hole, and the second water outlet hole 64 is not connected to any water inlet hole. That is, by changing the relative position between the moving piece 5 and the static piece 6, the on-off control of the water outlet channel is achieved. However, in use, the second water outlet hole 64 is usually used in cooperation with a solenoid valve to control the on-off of this water outlet channel. Therefore, the second water outlet hole 64 is usually selected to be in a state of being always connected to at least one of the cold water inlet hole 61 and the hot water inlet hole 62, that is, the second water outlet hole 64 always maintains a state of having water flowing out. Therefore, the valve core in this embodiment does not adopt the third water outlet mode, that is, only the first and second water outlet modes are required.
