[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Reference Figures 1 to 12 As shown, a kitchen faucet with multiple water outlet modes includes a housing 1, a water outlet pipe 2 rotatably connected to the housing 1, a water purifier control component 3 and a raw water control component 4 fixed to the housing 1. The water purifier control component 3 is used to control the water purification start and stop of the water purifier body, and the raw water control component 4 is used to control the raw water temperature adjustment and start / stop.

[0033] The outer casing 1 is provided with a valve core seat assembly 5. The valve core seat assembly 5 includes a valve core seat body 51 and a rotating seat 52 that is rotatably and sealingly connected to the valve core seat body 51. The valve core seat body 51 includes a cold water inlet channel 612, a hot water inlet channel 622, a mixing water channel 631, a main purified water channel 642, and a number of secondary purified water channels 652 arranged separately. The secondary purified water channels 652 are arranged in a circumferential array around the central axis of the main purified water channel 642. The rotating seat 52 includes an annular water passage 653 and a secondary purified water interface 654 that match the number of secondary purified water channels 652.

[0034] Below the valve core seat body 51 are provided a cold water inlet pipe 611, a hot water inlet pipe 621, a main purified water inlet pipe 641, and several secondary purified water inlet pipes 651. Inside the water outlet pipe 2 are provided a main purified water outlet pipe 643 and several secondary purified water outlet pipes 655.

[0035] The cold water inlet pipe 611 is connected to the cold water inlet channel 612, and the hot water inlet pipe 621 is connected to the hot water inlet channel 622. The cold and hot raw water enters the raw water control component 4, and after being mixed and regulated by the raw water control component 4, it enters the mixing channel 631, and finally flows out through the gap formed by the inner circumference of the outlet pipe 2 and the outer circumference of the main purified water outlet pipe 643 and the secondary purified water outlet pipe 655.

[0036] Different types of purified water flowing from the water purifier body flow into the main purified water inlet pipe 641 and several secondary purified water inlet pipes 651. The main purified water inlet pipe 641 is connected to the main purified water channel 642, and the main purified water outlet pipe 643 passes through the rotating seat 52 and is connected to the main purified water channel 642. Each of the secondary purified water inlet pipes 651 is connected to the secondary purified water channel 652. The annular water passage trough 653 is connected to the secondary purified water channel 652. The secondary purified water interface 654 is connected to the annular water passage trough 653, and the secondary purified water outlet pipe 655 is connected to the secondary purified water interface 654.

[0037] The raw water control component 4 includes a handle 41 and a mixing valve core 42 connected to the handle 41. Cold raw water and hot raw water enter the mixing valve core 42 to adjust the temperature. The ratio of cold raw water and hot raw water entering the mixing valve core 42 is adjusted by the handle 41 to achieve temperature regulation. The temperature-adjusted raw water enters the mixing channel 631 and finally flows out through the gap formed by the inner circumference of the outlet pipe 2 and the outer circumference of the main purified water outlet pipe 643 and the secondary purified water outlet pipe 655.

[0038] The advantages of the above embodiments are:

[0039] Firstly, the purified water system and the raw water system (meaning untreated or unpurified water, such as municipal water supply and groundwater) are not connected to each other, so there will be no cross-contamination during use;

[0040] Secondly, the water purifier body has different water output modes, which may include room temperature purified water, ice purified water, hot purified water and sparkling water. Among them, room temperature purified water, ice purified water and sparkling water can be supplied to the kitchen faucet through the main purified water inlet pipe 641, and hot purified water can be supplied to the kitchen faucet through the secondary purified water inlet pipe 651. This can avoid the phenomenon of hot and cold water mixing that may occur when ice purified water and hot purified water share the same pipe, and ensure that water at the required temperature can be accurately provided to the user, thus improving the user experience.

[0041] Thirdly, when the user rotates the water outlet pipe 2 to adjust the water outlet direction, since the main purified water outlet pipe 643 is connected to the valve core seat body 51 and the secondary purified water outlet pipe 655 is connected to the secondary purified water interface 654 of the rotating seat 52, the rotating seat 52 rotates along with the water outlet pipe 2 during the rotation process. This can prevent the main purified water outlet pipe 643 and the secondary purified water outlet pipe 655 from crossing and tangling, which would cause the pipes to be squeezed and affect the water flow rate.

[0042] Specifically, the water purifier control component 3 includes a knob 31 and a hollow encoder 33. When the knob 31 rotates, it drives the hollow encoder 33 to rotate, thereby switching the water purifier body to different water output modes. The rotation of the knob 31 drives the encoder disk 3311 of the hollow encoder 33 to rotate. During the rotation, the mechanical displacement is converted into an electrical signal. The electrical signal is transmitted to the processor of the water purifier body via wired or wireless means. The processor controls the water purifier body to switch between multiple water output modes, including room temperature purified water, ice water, hot water, and sparkling water.

[0043] As a specific structure of the water purifier control component 3, the water purifier control component 3 also includes a bracket 32. The outer shell 1 is provided with a first mounting groove 11. The end of the bracket 32 ​​is embedded in the first mounting groove 11. The knob 31 is sleeved on the outer periphery of the bracket 32. The knob 31 is provided with a control key 34. The control key 34 is used to control the water output start and stop of the water purifier body. The control key 34 is fastened to the hollow encoder 33. The knob 31 is provided with a mounting part 311. The hollow encoder 33 passes through the bracket 32 ​​and the mounting part 311 from the inside to the outside. One end of the hollow encoder 33 passing through the mounting part 311 is snapped by a retaining ring 35.

[0044] With the above structure, the hollow encoder 33 is fixed to the mounting part 311 by the retaining ring 35, and one end of the bracket 32 ​​is clamped by the mounting part 311 and the hollow encoder 33. The side end face of the control key 34 is flush with the side end face of the knob 31, which improves the aesthetics of the product. The control key 34 is inserted into the knob 31 from the side and is fastened to the hollow encoder 33 to achieve the overall structural assembly. The structure is stable after assembly.

[0045] As an embodiment of controlling the water outlet on and off in a water purifier, the control key 34 is movable along the axial direction of the knob 31. The hollow encoder 33 includes an encoder body 331, a PCB board 332, and a tactile switch 333. The encoder body 331 and the tactile switch 333 are disposed on the PCB board 332. The button area of ​​the tactile switch 333 is directly opposite the hollow area of ​​the encoder body 331. The control key 34 passes through the hollow area of ​​the encoder body 331 and controls the water outlet on and off by pressing the tactile switch 333. When the user presses the control key 34, the control key 34 triggers the tactile switch 333. The electrical signal generated by the tactile switch 333 is transmitted to the processor of the water purifier via wired or wireless means. The processor controls the water purifier to turn the water outlet on or off. After pressing the tactile switch 333, its built-in reset spring drives the control key 34 to reset. In this embodiment, a spring (not shown in the figure) can be provided in the control key 34 and the mounting part 311 to improve the reset speed of the control key 34.

[0046] In another embodiment of controlling the water purifier's main body to turn the water outlet on and off, the control key 34 includes a touchscreen exposed on the knob 31. By touching the touchscreen, the user controls the water outlet of the main body. In this embodiment, the electrical signal generated by the user touching the touchscreen is transmitted to the controller in the main body of the water purifier via wired or wireless means, thereby controlling the water outlet of the main body. Furthermore, the water outlet mode of the main body can be displayed on the touchscreen, making operation convenient.

[0047] In a preferred embodiment, the bracket 32 ​​is provided with a halo section 321, and the different colors of the halo section 321 correspond to the different water output modes of the water purifier body. Users can identify which water output mode the water purifier body has switched to by recognizing the light source color of the halo section 321, thus providing users with intuitive feedback on the water output mode through the light source color.

[0048] In a preferred embodiment, the water purifier control component 3 further includes several spring pins 36 embedded in the mounting portion 311. The bracket 32 ​​is provided with several groove portions 322 arranged in a circumferential array. By rotating the knob 31, the spring pins 36 are sequentially embedded into the groove portions 322. Through the cooperation between the spring pins 36 and the grooves, the knob 31 generates audible feedback during rotation. Due to the obvious clicking sound during rotation, if the user accidentally touches the knob 31, they can immediately perceive that the knob 31 has been rotated and adjust it in time, avoiding accidental switching of the water output mode due to misoperation. In particular, it can prevent accidental switching to the hot water output mode, which could cause scalding to the user.

[0049] To ensure the stability of the connection structure, the control key 34 is provided with several first hook portions 341 that engage with the encoder disk 3311 of the hollow encoder 33, the retaining ring 35 is provided with several second hook portions 351 that engage with the hollow encoder 33, and the bracket 32 ​​is provided with several third hook portions 323 that engage with the first mounting groove 11. This hook structure facilitates the assembly of the water purifier control component 3.

[0050] The water purifier control component 3 can be connected to the outer casing 1 via the third hook portion 323. Alternatively, the water purifier control component 3 can be connected to the outer casing 1 via screws. These connection methods facilitate disassembly from the outer casing 1 for replacement or repair when the electronic components inside the water purifier control component 3 are damaged.

[0051] The assembly steps of the water purifier control component 3 are as follows: The hollow encoder 33 is inserted into the bracket 32 ​​from back to front. Epoxy resin can be injected into the rear end of the hollow encoder 33 and the bracket 32 ​​to protect the electronic components and prevent moisture intrusion. Then, it is snapped together by a retaining ring 35. A spring pin 36 is embedded in the mounting part 311 of the knob 31, and then inserted into the bracket 32 ​​from front to back. The control key 34 is inserted into the knob 31 from front to back and connected to the hollow encoder 33, completing the assembly. The assembly operation is simple. The hollow structure of the hollow encoder 33 reduces the space occupied by the water purifier control component 3, resulting in a compact structure.

[0052] The main purified water outlet pipe 643 passes through the central axis of the rotating seat 52. This arrangement ensures that the main purified water outlet pipe 643 will not undergo lateral displacement during the rotation of the rotating seat 52 driven by the outlet pipe 2. When the rotating seat 52 rotates, the secondary purified water outlet pipe 655 rotates around the main purified water outlet pipe 643, reducing the possibility of them intersecting. Furthermore, the main purified water outlet pipe 643 is vertically arranged, eliminating any bends that could affect the water output.

[0053] The valve core seat assembly 5 further includes an upper cover 53 and a pressure ring 54. The upper cover 53 is embedded in the outer shell 1. The inner circumference of the upper cover 53 is provided with a limiting surface 531 and a first thread 532. The valve core seat body 51 is provided with a second thread 511 that connects to the first thread 532. The upper end face of the pressure ring 54 abuts against the limiting surface 531, and the lower end face of the pressure ring 54 abuts against the rotating seat 52. During the threaded connection between the valve core seat body 51 and the upper cover 53, the limiting surface 531 and the pressure ring 54 press the rotating seat 52 into the valve core seat body 51, preventing the rotating seat 52 from detaching from the valve core seat body 51.

[0054] The valve core seat body 51 is provided with a positioning post 512, and the pressure ring 54 is provided with a positioning hole 541 that cooperates with the positioning post 512. The pressure ring 54 is also provided with a water passage hole 632 that communicates with the mixing channel 631. The cooperation between the positioning hole 541 and the positioning post 512 prevents the water outlet pipe 2 from driving the pressure ring 54 to rotate during rotation, thus preventing the water passage hole 632 from being directly aligned with the mixing channel 631 and avoiding obstruction of the flow of mixed raw water.

[0055] The main purified water outlet pipe 643 is a three-part pipe. The main purified water outlet pipe 643 is mainly used for the flow of room temperature purified water, ice water and sparkling water in the water purifier body. By using a three-part pipe in the main purified water outlet pipe 643, the water flow rate of purified water, especially the water flow rate of sparkling water, is increased, thereby improving the user experience.

[0056] A plurality of first sealing rings 55 are provided between the valve core seat body 51 and the rotating seat 52. The first sealing rings 55 ensure the sealing effect between the valve core seat body 51 and the rotating seat 52.

[0057] The free end of the water outlet pipe 2 is provided with a water outlet head 21. The water outlet head 21 has a first channel 644 and a second channel 656. The first channel 644 is connected to the main purified water outlet pipe 643 and is equipped with a check valve 645. The second channel 656 is connected to the secondary purified water outlet pipe 655. The check valve 645 in the first channel 644 prevents the backflow of non-heated purified water, effectively preventing harmful substances such as external bacteria and viruses from entering the water purifier body with the backflow of non-heated purified water, thereby maintaining the cleanliness of the filter element and the inside of the water purifier and preventing water pollution. The second channel 656 is used to discharge hot purified water and allows backflow, and can adopt instant heating technology. When the user needs hot water, the cold purified water entering the instant heating module of the water purifier body is quickly heated and flows out, achieving instant hot water without long waiting time, which is convenient and fast. Whether it's non-thermal or thermal water purification, both systems maintain good water quality within their respective channels, ensuring that every drop of water used by the user meets healthy and safe standards, providing a better water experience for the family.

[0058] In addition, the check valve 645 can prevent water in contact with the outside in the first channel 644 from flowing back into the water purifier body when the water purifier body controls hot or non-hot water backflow, which would lead to problems such as inaccurate water temperature control.

[0059] This utility model also includes a fixing component 7, which includes an upper clamping plate 71 and a lower clamping plate 72 disposed at the upper and lower ends of the basin. The upper clamping plate 71 is threadedly connected to the outer shell 1, and an installation tube 73 is threadedly connected to the inner side of the upper clamping plate 71. The upper clamping plate 71 and the installation tube 73 can be an integral structure or a separate structure. The lower clamping plate 72 is threadedly connected to the installation tube 73. The upper end of the upper clamping plate 71 supports the valve core seat body 51. With the above structure, the outer shell 1 can be fixed to the basin, while the valve core seat body 51 and the upper cover 53 are supported on the outer shell 1.
