Description

Technical Field

[0001] This invention relates to the field of fluid control equipment technology, specifically to an intelligent interactive faucet and its control method. Background Technology

[0002] With the popularization of smart home technology, modern bathroom and kitchen water terminals have gradually evolved from simple mechanical switches into intelligent fluid control systems that integrate cold water, hot water, and special water quality (such as soda water and purified water) output. Users' needs for faucets are no longer limited to basic on / off control, but extend to refined management and convenient operation of water temperature, water flow rate, and liquid dispensing mode.

[0003] In existing technologies, to address the control challenges of multi-functional integration, full-touchscreens are increasingly being applied to smart faucets, attempting to achieve multi-mode management through a graphical interface. However, in real-world water usage scenarios, users' hands are often covered in water stains, foam, or oil. Relying solely on capacitive touchscreens for temperature or flow adjustment is prone to malfunctions, accidental touches, or abrupt changes in values ​​due to humid environments or slippery fingers. Furthermore, the lack of physical tactile feedback and confirmation makes it difficult for users to achieve stepless and precise continuous adjustment through touch.

[0004] To compensate for the limitations of touch interaction in fine-tuning, some existing solutions attempt to introduce a knob structure. However, the current common structural layouts mainly suffer from two types of defects: one is that the knob is set as an independent physical component separated from the display area, causing the user's line of sight to switch back and forth between the knob and the screen when adjusting, resulting in a fragmented "display and control separation" experience; the other solution integrates the display screen on the knob end, but the screen rotates synchronously with the knob. This not only makes it difficult for users to read tilted or even inverted parameter information on the screen when making large adjustments, but also poses a challenge to the reliability of the internal electronic connection structure.

[0005] Therefore, how to overcome the inaccuracy of wet-hand touch control while highly integrating multiple liquid dispensing modes, and solve the problems of screen following or display and control separation in existing knob structures, so as to achieve intuitive, accurate and ergonomic fluid control, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] (i) The technical problem to be solved by the present invention is that existing smart faucets cannot simultaneously guarantee the accuracy of control and the intuitiveness of operation when switching between multiple modes and making fine adjustments.

[0007] (II) Technical Solution To address the aforementioned technical problems, this invention provides an intelligent interactive faucet, comprising: A faucet base includes an inner cavity, within which a liquid inlet pipe and a fluid actuator are provided; A liquid outlet terminal is located on the faucet base and connected to the liquid inlet pipe; The control interaction component is located on the top of the faucet base and includes a display interaction unit that is stationary relative to the faucet base, a rotating top cover that can rotate infinitely around the central axis of the display interaction unit, and a control motherboard. The display interaction unit has a display interface for displaying visual information and a touch sensing area for receiving touch commands. The display interface is used to display the current liquid dispensing mode and liquid dispensing parameter information, and the touch sensing area is used to receive touch commands to switch the liquid dispensing mode. A rotation sensor is located at the relative motion interface between the rotating top cover and the display interaction unit and is connected to the control motherboard, and is used to output an adjustment signal in response to the rotation of the rotating top cover; The control motherboard is connected to the fluid actuator and is configured to receive the touch command and the adjustment signal, and to switch the liquid discharge mode of the fluid actuator in response to the touch command, and to drive the fluid actuator to adjust the liquid discharge parameters in the current liquid discharge mode in response to the adjustment signal.

[0008] According to one embodiment of the present invention, the display interaction unit includes a fixed support member and a circular screen; the top of the fixed support member is provided with a screen receiving groove, the circular screen is embedded in the screen receiving groove, and the front of the circular screen serves as the display interface and is provided with a touch sensing area; the top of the faucet base is formed with a mounting groove, the bottom end of the fixed support member extends into the mounting groove and is fixedly connected to the faucet base; the outer peripheral wall of the fixed support member is provided with a bearing inner seat coaxial with the central axis; the rotating top cover has an annular cover structure and covers the outer periphery of the circular screen, the bottom end of the rotating top cover extends into the mounting groove to form an inner skirt, and the inner peripheral wall of the inner skirt is provided with a bearing outer seat radially opposite to the bearing inner seat; an annular mounting space is defined between the bearing inner seat and the bearing outer seat, and a bearing assembly is provided in the annular mounting space; the rotating top cover is supported on the fixed support member by the bearing assembly and rotates infinitely around the central axis relative to the fixed support member.

[0009] In the above structure, the fixed support, through bottom fixation and top mounting, provides a static mounting reference for the circular screen independent of rotation, ensuring the display interface remains stable and upright. Based on this, the annular mounting space formed by the inner and outer bearing seats provides precise axial and radial positioning for the bearing assembly, allowing the rotating top cover to be fully supported by the bearing assembly on the outer periphery of the fixed support. This bearing-centric connection effectively constrains the radial runout of the rotating top cover, ensuring its rotational coaxiality relative to the fixed support, and transforming the friction of the rotating interface into a low-damping rolling fit. This ensures smooth and stable rotation operation while achieving a static central display and infinitely rotating peripheral functional zones.

[0010] According to one embodiment of the present invention, a sealing partition is provided in the inner cavity of the faucet base, the sealing partition dividing the inner cavity of the faucet base into the mounting groove located in the upper part and the receiving cavity located in the lower part; A first sealing ring is provided between the outer peripheral wall of the sealing partition and the inner side wall of the faucet base, and the sealing partition is sealed to the faucet base through the first sealing ring. The control motherboard is disposed in the mounting slot, and the liquid inlet pipe and the fluid actuator are located in the accommodating cavity; The sealing partition has a wire passage that connects the mounting groove and the accommodating cavity. The control board is electrically connected to the fluid actuator through a wire passing through the wire passage. The wire passage is provided with a sealing medium for sealing the gap between the wire and the wire passage.

[0011] In the above structure, a sealing partition separates the inner cavity of the faucet base axially, creating an electrical dry zone (containing the control board in the upper mounting slot) and a fluid wet zone (containing the piping and fluid actuators in the lower accommodating cavity), achieving dry-wet separation in terms of spatial architecture. A first sealing ring establishes a continuous radial sealing boundary between the outer periphery of the partition and the inner wall of the base, effectively blocking the upward migration of condensate or potential leakage fluid from the lower accommodating cavity along the inner wall interface. Simultaneously, the control board is placed in an isolated, independent space, physically away from fluid condensation sources. For necessary cross-zone electrical connections, a sealing medium filled in the wiring channels seals the wire gaps, reducing the risk of moisture creeping circumferentially along the wires and intruding into the upper space via capillary action. This ensures the effectiveness of electrical connections while improving the protection reliability and operational safety of the core electrical control unit in long-term water-related environments.

[0012] According to one embodiment of the present invention, the top outer edge of the sealing partition extends upward to form an annular water-blocking flange; An annular water-blocking gap is formed between the outer wall of the annular water-blocking flange and the inner wall of the mounting groove of the faucet base. The bottom end of the inner skirt of the rotating top cover extends to the lower side of the outer side of the bearing outer seat and is suspended and inserted in the annular water-blocking gap, so that the inner skirt and the annular water-blocking flange form a non-contact labyrinth seal.

[0013] In the aforementioned structure, a non-contact labyrinth seal is constructed by vertically offsetting the annular water-blocking flange at the top of the sealing partition with the inner skirt of the rotating cover. This structure significantly increases the path length and flow resistance for external liquids to penetrate inward by forming multiple zigzag channels between the inner skirt and the water-blocking flange. Gravity interception and path deflection effectively block external splashing water or condensate, forming the first physical protective barrier for the internal electrical control area. Simultaneously, given the suspended design of this seal, it completely avoids the end-face friction and wear caused by traditional contact seals while preventing moisture intrusion. This achieves dynamic waterproofing without increasing rotational resistance torque, ensuring that the adjustment feel of the rotating cover remains light, smooth, and stable throughout long-term use.

[0014] According to one embodiment of the present invention, the outer side wall of the rotating top cover and the outer side wall of the faucet base have the same radial outer contour dimension at the joint, such that the outer side wall of the rotating top cover and the outer side wall of the faucet base are coplanarly continuous in the axial direction. The bottom of the rotating top cover and the top of the faucet base are provided with a gap at the joint to eliminate end-face friction when the rotating top cover rotates relative to the faucet base.

[0015] In the aforementioned structure, by ensuring that the rotating top cover and the faucet base have a consistent radial outer contour at the connection point, axial coplanar continuity in appearance is achieved. This integrated form not only eliminates the visual discontinuity caused by traditional stepped structures but also effectively prevents stains and grease from accumulating at abrupt contour changes, facilitating cleaning and maintenance. Simultaneously, the clearance gap at the connection point physically isolates the rotating moving parts from the stationary parts, ensuring that the guidance and load-bearing of the rotational motion are entirely borne by the internal bearing assembly. This fundamentally eliminates mechanical friction and surface wear caused by end-face contact and effectively avoids jamming and abnormal noises caused by assembly errors, thermal expansion and contraction, or foreign object insertion, thus ensuring consistent damping feel and stable appearance quality of the rotating top cover during long-term use.

[0016] According to one embodiment of the present invention, the liquid inlet pipeline includes a cold water inlet pipe, a hot water inlet pipe, and a soda water inlet pipe; The faucet base is provided with a pipe inlet that communicates with the accommodating cavity. The cold water inlet pipe, the hot water inlet pipe and the soda water inlet pipe pass into the accommodating cavity through the pipe inlet. The fluid actuator includes a multi-way electrically controlled valve assembly, and the cold water inlet pipe, the hot water inlet pipe, and the soda water inlet pipe are connected to the liquid outlet terminal through the multi-way electrically controlled valve assembly; The control motherboard is configured to drive the multi-channel electronically controlled valve assembly in response to the liquid discharge mode, so that the cold water inlet pipe, the hot water inlet pipe and the soda water inlet pipe are connected to the liquid discharge terminal with a flow ratio corresponding to the liquid discharge mode.

[0017] In the above structure, the inlet pipeline includes a cold water inlet, a hot water inlet, and a soda water inlet. These three pipelines are uniformly introduced into the receiving cavity through pipeline inlets and establish a controllable connection with the outlet terminal through a multi-channel electrically controlled valve assembly. This allows for the integrated supply of multiple media, including cold water, hot water, and soda water, within a single faucet terminal. The control board drives and controls the multi-channel electrically controlled valve assembly, enabling the three pipelines to switch on / off and adjust flow ratios according to the selected outlet mode. This achieves continuous adjustment of the hot / cold water ratio and temperature in the normal water usage mode, and allows for direct output of soda water or a mixture with cold / hot water in the soda water-related mode. Therefore, the outlet mode and parameter settings determined on the interactive side can be stably mapped to valve combinations and ratio control, improving the controllability of multi-mode switching and the consistency of outlet output.

[0018] According to one embodiment of the present invention, the liquid outlet terminal has a liquid outlet fixedly protruding from the faucet base, and the liquid outlet has a liquid outlet axis along the liquid outlet direction; The liquid outlet axis and the central axis of the display interaction unit form a preset obtuse angle; So that when the liquid dispensing terminal is installed with the liquid dispensing axis pointing vertically downward, the central axis of the display interaction unit is tilted relative to the vertical direction, causing the display interface to present an observation state tilted to one side.

[0019] In the above structure, by setting the liquid outlet axis to a preset obtuse angle with the central axis of the display interaction unit, the display interface is tilted to one side and is in a non-collinear offset state when the faucet is installed with the liquid outlet pointing vertically downwards. This tilted layout makes the display interface more aligned with the user's line of sight when standing, reducing ambient light reflection interference that may occur with horizontal arrangements and the inconvenience of reading from a large angle, thus improving the convenience of information reading. At the same time, the tilted interaction plane is more ergonomic, making it easier for users to complete touch command input and parameter adjustment operations by rotating the top cover while maintaining a normal water-drawing posture, thereby making it easier to synchronize interactive operations and visual confirmation.

[0020] According to one embodiment of the present invention, the liquid outlet terminal includes a tubular liquid outlet and a manifold connector inserted into the tubular liquid outlet; A second sealing ring is provided between the outer peripheral wall of the manifold adapter and the inner peripheral wall of the tubular outlet, and the manifold adapter is sealed to the tubular outlet through the second sealing ring.

[0021] In the above structure, the liquid outlet terminal adopts a coaxial integrated architecture with a manifold adapter inserted inside the tubular liquid outlet. The manifold adapter, as the converging carrier of the internal fluid, achieves unified guidance and modular assembly of multiple fluid paths, facilitating the integration and connection of flow paths within a confined space. Based on this, a second sealing ring is used to establish a continuous radial sealing boundary between the outer periphery of the manifold adapter and the inner wall of the tubular liquid outlet, effectively sealing the mating gaps and suppressing fluid leakage and backflow. Simultaneously, the elastic pre-tightening effect provided by the sealing ring compensates for machining tolerances and absorbs fretting vibrations caused by fluid impact, thereby preventing loosening of the connection and ensuring the sealing reliability of the liquid outlet terminal during long-term use.

[0022] According to one embodiment of the present invention, the outer wall surface of the rotating top cover is provided with a surrounding anti-slip texture. By providing an anti-slip texture on the outer wall of the rotating top cover, the friction coefficient of the contact surface is effectively increased, ensuring that the user can achieve reliable torque transmission and stable adjustment and control even under working conditions such as wet hands, and avoiding slippage.

[0023] The present invention also provides a control method for the intelligent interactive faucet according to any of the above claims, comprising the following steps: S1. In response to a user's touch command applied to the display interaction unit, control the fluid execution unit to switch to the target liquid dispensing mode, and determine the corresponding adjustable controllable parameters under the target liquid dispensing mode; the adjustable controllable parameters include liquid dispensing temperature parameters or liquid dispensing flow rate parameters; S2. Real-time detection of the rotation of the rotating top cover relative to the display interaction unit, identification of the rotation direction and rotation displacement, and generation of a stepless adjustment signal containing direction and magnitude information accordingly. S3. Based on the stepless adjustment signal, the control motherboard drives the fluid actuator to perform the following bidirectional stepless adjustment on the liquid inlet pipeline: When the adjustable and controllable parameter is the outlet temperature parameter, the ratio adjustment logic is executed: in response to the stepless adjustment signal, the fluid actuator is driven to steplessly adjust the flow mixing ratio of the inlet pipeline; wherein, the rotation direction determines the increasing or decreasing trend of the flow mixing ratio, and the rotation displacement determines the change range of the flow mixing ratio; When the adjustable and controllable parameter is the liquid flow rate parameter, the opening adjustment logic is executed: in response to the stepless adjustment signal, the fluid actuator is driven to steplessly adjust the flow opening of the liquid inlet pipe; wherein, the rotation direction determines the increasing or decreasing trend of the flow opening, and the rotation displacement determines the change range of the flow opening.

[0024] The above method constructs a composite interactive architecture of "touch-based mode setting + rotation-based parameter adjustment". First, the target dispensing mode is locked via touch commands, and the controlled parameters are simultaneously bound, establishing a clear target for adjustment and avoiding logical confusion across multiple modes. Then, the physical properties of the rotational motion are used to generate a stepless adjustment signal containing both direction and magnitude information, supporting continuous bidirectional parameter adjustment rather than discrete jumps. The core lies in the control board's ability to perform self-adaptive logic switching based on parameter type: flexibly mapping the same rotational input to "ratio adjustment" in temperature mode or "opening adjustment" in flow mode. This mechanism achieves functional reuse of a single physical knob, establishing a unified "rotation equals increase / decrease" interactive semantics, ensuring consistent operating logic and predictable control response for users across different dispensing modes.

[0025] (III) Beneficial effects of the present invention: The present invention constructs a composite interactive architecture in which the display interaction unit is relatively stationary and fixed while the rotating top cover can rotate infinitely around its central axis. The central stationary area carries touch commands and visual information, while the outer rotating area outputs physical adjustment signals, realizing the logical decoupling and coordination of touch switching of liquid dispensing mode and infinitely adjustable physical parameters. This dynamic and static structural layout ensures that the display interface always maintains the best static observation posture during the adjustment process, eliminating visual deviation and reading difficulties caused by screen movement from a physical perspective. At the same time, the mechanical displacement of the rotation action directly maps the change in liquid parameters, effectively overcoming the numerical jump and accidental touch defects of pure touch adjustment under wet manual conditions. Thus, in a highly integrated multi-functional control scenario, it takes into account both the intuitive visibility of interactive operation and the continuous accuracy of fluid control.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation

[0030] This embodiment provides an intelligent interactive faucet, suitable for scenarios requiring integrated control and fine adjustment of multiple fluid streams, such as home kitchens, bathroom sinks, drinking water stations, or commercial bars. Figure 1 As shown, the smart interactive faucet is usually installed on the countertop or the edge of the sink. It is usually fixed vertically by passing through the mounting surface with the fixing sleeve 24, so that the liquid outlet terminal 4 is aligned with the container or basin with the liquid outlet 41 pointing vertically downward. This allows the user to intuitively select the mode and adjust the parameters without changing the normal water intake posture while standing or bending over to take water.

[0031] like Figure 2 and Figure 3 As shown, the faucet base 1 serves as the basic support frame of the entire machine. Its internal space is functionally divided into two independent areas: the lower part forms a receiving cavity 12 to accommodate the liquid inlet pipe 2 and the fluid actuator 3, creating a wet area for fluid transmission and execution; the upper part forms an upward-opening mounting groove 11 for assembling the display and interaction unit 5, the rotating top cover 6, and the control motherboard 7, creating a dry area for electronic control and interaction. The display and interaction unit 5 is fixed in a relatively static manner in the central area of ​​the mounting groove 11, providing a stable visual interface, while the rotating top cover 6 is arranged around the outer periphery of the display and interaction unit 5 and can rotate infinitely around the central axis, thus forming an integrated layout that combines static display and dynamic adjustment in terms of the overall appearance and function of the machine. The following will describe in detail the structural details, sealing relationships, and control logic of each part of this intelligent interactive faucet with reference to the attached drawings.

[0032] like Figures 3 to 10As shown, the faucet base 1 includes an inner cavity. The faucet base 1 can adopt various shapes to adapt to different countertops and installation space requirements. In this embodiment, it can have an approximately hemispherical appearance. To ensure stable coaxial guidance and uniform circumferential fit when the rotating cover 6 rotates around the central axis, the inner wall of the faucet base 1 in the connection area adjacent to the rotating cover 6 forms a circular fitting reference surface in the circumferential direction around the central axis. This provides a continuous circumferential boundary for the inner circumferential sidewall of the mounting groove 11, the inner skirt 61 of the rotating cover 6, and the water-blocking gap described later. Furthermore, the faucet base 1 can form a stop step, end face positioning shoulder, or circumferential guide surface in this connection area for positioning. This provides a reference for the radial outer contour and axial height of the rotating cover 6 during assembly, ensuring that the rotating cover 6 maintains a stable relative gap and coaxiality with the outer wall of the faucet base 1 during rotation. The inner cavity is equipped with an inlet pipe 2 and a fluid actuator 3. The inner cavity of the faucet base 1 is equipped with a sealing partition 514, which divides the inner cavity of the faucet base 1 into the upper mounting groove 11 and the lower receiving cavity 12. The upper area can support the control interaction components and electrical components, while the lower area is used to arrange the inlet pipe 2 and the fluid actuator 3 and form a connection with the external pipe inlet end. This achieves spatial layering of the electrical arrangement area and the fluid arrangement area from the structural skeleton level. The mounting groove 11 extends around the central axis in the circumferential direction and forms a receiving space for the display interaction unit 5, the rotating top cover 6 and its inner skirt 61. The receiving cavity 12 is located below the mounting groove 11 and can form a larger receiving volume in the axial direction to facilitate the connection of the inlet pipe 2, the arrangement of the fluid actuator 3 and the layered routing of wires and pipes.

[0033] like Figure 3 , 6 class Figure 7 As shown, the control and interaction components are located on the top of the faucet base 1, including a display and interaction unit 5 that is statically fixed relative to the faucet base 1, a rotating top cover 6 that can rotate infinitely around the central axis of the display and interaction unit 5, and a control motherboard 7; wherein, the display and interaction unit 5 forms an interaction plane facing the user, the rotating top cover 6 surrounds the outer periphery of the display and interaction unit 5 and forms a force-applyable rotating control interface in the circumferential direction, and the control motherboard 7 is arranged in the mounting slot 11 to shorten the signal connection path between the display and interaction unit 5 and the rotation sensor 8. Figures 3 to 5As shown, the outer wall of the rotating cover 6 and the outer wall of the faucet base 1 have the same radial outer contour dimension at the joint, so that the outer wall of the rotating cover 6 and the outer wall of the faucet base 1 are coplanar and continuous in the axial direction, thereby forming a continuous transition in appearance and making the boundaries of the rotating part and the fixed part located on the same radial shape reference. In some implementations, the joint between the rotating cover 6 and the faucet base 1 can form a continuous circumferential appearance transition fillet or chamfer, making the coplanar continuous outer contour more visually coherent and reducing the possibility of water, dirt or oil stains accumulating at the joint edge. Correspondingly, the bottom end of the rotating top cover 6 and the top end of the faucet base 1 are provided with a clearance gap 62 at the joint, so that the rotating top cover 6 does not interfere with the end face when rotating relative to the faucet base 1. This limits the load-bearing and guiding functions to the internal bearing assembly 9 and reduces the risk of end face friction caused by assembly tolerances, thermal expansion and contraction or foreign objects. In some implementations, the clearance gap 62 can be continuous in the circumferential direction to avoid periodic rubbing points during rotation. The clearance gap 62 can also form a relative shielding relationship with the opening edge of the mounting groove 11 to reduce the probability of external water droplets directly entering the mounting groove 11. The outer wall surface of the rotating top cover 6 is provided with a surrounding anti-slip texture 63. The anti-slip texture 63 can be achieved by knurling, ribs, dot matrix protrusions, or covering with anti-slip material, etc., to form a stable friction contact surface in the circumferential direction of the outer wall, so that the user can still apply a reliable circumferential torque to the rotating top cover 6 and maintain the controllability of the rotation adjustment action even when the user's hands are wet or have cleaning agents on them. In some implementations, the anti-slip texture 63 can form multiple circumferentially distributed friction bands along the axial direction, or form a locally deepened grip area around the periphery of the rotating top cover 6 to adapt to the torque input under different grip postures.

[0034] The display interaction unit 5 has a display interface for displaying visual information and a touch sensing area for receiving touch commands. The display interface is used to display the current liquid dispensing mode and liquid dispensing parameter information, and the touch sensing area is used to receive touch commands to switch the liquid dispensing mode. In this embodiment, the display interaction unit 5 includes a fixed support 51 and a circular screen 52. The fixed support 51 serves as a static structural base for supporting the circular screen 52 and forming a fixed connection with the faucet base 1. The top of the fixed support member 51 is provided with a screen receiving groove 511. The circular screen 52 is embedded in the screen receiving groove 511. The front of the circular screen 52 forms the display interface and is provided with a touch sensing area, so that the display and touch are integrated on the same front interactive plane. The circular screen 52 and the screen receiving groove 511 can be positioned and fixed by means of buckle limiting, screw pressing, adhesive fixing or sealing ring pressing, etc. The radial position and axial height of the circular screen 52 can be constrained by the positioning shoulder and stop structure so that the circular screen 52 remains stationary and does not wobble during the rotation of the rotating cover 6. In some implementations, the screen receiving groove 511 can form a clearance notch or wire pressing area at its bottom or wall for wiring, so that the wires of the circular screen 52 can be led out along the back side of the fixed support member 51 and protected by the fixed support member 51. The top of the faucet base 1 has a mounting groove 11. The bottom end of the fixing support 51 extends into the mounting groove 11 and is fixedly connected to the faucet base 1. The fixing support 51 and the faucet base 1 can be connected by screw locking, snap fastening, welding, or integral molding. The circumferential positioning surface and the end face positioning shoulder can be matched to ensure that the central axis of the fixing support 51 is coaxial with the circumferential fitting reference of the faucet base 1, thereby providing a consistent assembly reference for subsequent bearing support and labyrinth seal. Referring to the structure shown in the attached figure, in this embodiment, the fixing support 51 can be connected by a fixing connecting rod 515. The fixed connecting rod 515 is connected to the faucet base 1 by a screw fixing method. The fixed connecting rod 515 can be inserted along the central axis or extended downward from the fixed support member 51 to seal and connect with the sealing partition member 514 and cooperate with the corresponding thread structure in the faucet base 1. This allows the fixed support member 51 to be pressed and positioned in the axial direction and torsionally restrained in the circumferential direction. In some implementations, the fixed connecting rod 515 can be a single rod to form a central pressing, or multiple rods can be distributed circumferentially to improve the resistance to eccentric loads. It can also cooperate with the positioning boss at the bottom of the fixed support member 51 and the positioning recess of the faucet base 1 to achieve self-positioning during assembly.

[0035] To enable the rotating top cover 6 to rotate infinitely around the central axis, the outer peripheral wall of the fixed support member 51 is provided with a bearing inner seat 512 coaxial with the central axis. The bearing inner seat 512 can be an annular seat surface continuously arranged in the circumferential direction or a seat surface structure composed of multiple circumferentially spaced support segments, used to form a radial and axial positioning fit with the bearing assembly 9. In some implementations, the bearing inner seat 512 can simultaneously form a radial positioning surface and an axial support surface to limit the inner support part of the bearing assembly 9 and reduce the risk of axial movement or radial sway of the bearing assembly 9. The rotating top cover 6 has an annular cover structure and covers the outer periphery of the circular screen 52. The bottom end of the rotating top cover 6 extends into the mounting groove 11 to form an inner skirt 61. The inner skirt 61 extends downward along the axial direction and surrounds the outer periphery of the fixed support member 51 in the circumferential direction, so that the rotating top cover 6 and the fixed support member 51 form a coaxial sleeve relationship in space. The inner peripheral wall of the inner skirt 61 is provided with a bearing outer seat 611 that is radially opposite to the bearing inner seat 512. The bearing outer seat 611 and the bearing inner seat 512 are radially opposite and form a fitting height difference in the axial direction, thereby defining an annular mounting space between them. The bearing assembly 9 is provided in the annular mounting space. The bearing assembly 9 can be a ball bearing, needle roller bearing, or sliding bearing, etc. The bearing assembly 9 forms a rolling or low-friction support between the inner bearing housing 512 and the outer bearing housing 611, so that the rotating upper cover 6 is supported on the fixed support member 51 by the bearing assembly 9 and can rotate infinitely about the central axis relative to the fixed support member 51. In some implementations, the bearing assembly 9 can adopt a structure with inner and outer rings and form a press fit or interference fit with the inner bearing housing 512 and the outer bearing housing 611, respectively, to achieve stable coaxial positioning. Alternatively, the bearing assembly 9 can adopt an integral sliding bearing and reduce frictional resistance through the self-lubricating properties of the material or surface treatment. Furthermore, the inner bearing housing 512 and the outer bearing housing 611 can form mutually cooperating limiting shoulders in the axial direction, so that the bearing assembly 9 is confined within the annular installation space after assembly and is not easy to fall off, while allowing the rotating cover 6 to rotate continuously in the circumferential direction; under this support relationship, the rotation guide of the rotating cover 6 is provided by the bearing assembly 9, and the clearance gap 62 is used to isolate the rotating cover 6 from the end face contact with the faucet base 1, so that the friction source of the rotational motion is concentrated on the internal rolling or sliding interface of the bearing assembly 9 and the stability of the rotational resistance torque is maintained, and the change of the gap at the joint appearance or the deterioration of the feel due to end face wear is avoided.

[0036] A first sealing ring 516 is provided between the outer peripheral wall of the sealing partition 514 and the inner side wall of the faucet base 1. The sealing partition 514 is sealed to the faucet base 1 through the first sealing ring 516, so as to establish a continuous radial sealing boundary on the outer periphery of the sealing partition 514 and reduce the possibility of water vapor or condensate in the lower accommodating cavity 12 migrating upward along the inner wall of the base. In some implementations, the first sealing ring 516 can be set in the sealing ring mounting groove 11 on the outer periphery of the sealing partition 514 and form a radial compression with the inner side wall of the faucet base 1, or the first sealing ring 516 can be set in the circumferential groove on the inner side wall of the faucet base 1 and cover the outer periphery of the sealing partition 514 to provide a covering seal, so as to maintain a continuous seal even when assembly tolerances exist. The control motherboard 7 is disposed within the mounting groove 11, and the liquid inlet pipe 2 and the fluid actuator 3 are located within the accommodating cavity 12, thus spatially separating the control motherboard 7 from the liquid inlet pipe 2 and the fluid actuator 3. In some implementations, the control motherboard 7 can be positioned by a fixed support 51 or a positioning post, pressing step, or snap-fit ​​structure formed by the faucet base 1 within the mounting groove 11, thereby reducing the risk of displacement of the control motherboard 7 during vibration or rotational operation. To achieve electrical connection between the control motherboard 7 and the fluid actuator 3, a wire passage 5141 is provided on the sealing partition 514 to connect the mounting groove 11 and the accommodating cavity 12. The control motherboard 7 is electrically connected to the fluid actuator 3 through a wire passing through the wire passage 5141, and a sealing medium 5142 is provided within the wire passage 5141 to seal the gap between the wire and the wire passage 5141. The sealing medium 5142 can be a potting compound, sealant, elastic sealing plug, or a sealing material with self-adaptive covering ability to form a circumferential sealing interface between the outer periphery of the conductor and the inner wall of the wire passage 5141, thereby reducing the risk of water vapor penetrating upward along the outer periphery of the conductor or the gap of the wire passage 5141, and maintaining the continuity of the seal when the conductor swings or expands and contracts due to thermal expansion and contraction; in some implementations, the sealing medium 5142 can form sealing end faces at both ends of the wire passage 5141, or form a locally thickened sealing section in the middle of the wire passage 5141, so as to improve the blocking effect on the circumferential water creep path of the conductor.

[0037] Regarding the dynamic protection of the rotating interface, the top outer edge of the sealing partition 514 extends upward to form an annular water-blocking flange 5143. The annular water-blocking flange 5143 is arranged around the central axis in the circumferential direction and forms a relative interface with the inner sidewall of the mounting groove 11 in the circumferential direction. An annular water-blocking gap 111 is formed between the outer sidewall of the annular water-blocking flange 5143 and the inner sidewall of the mounting groove 11 of the faucet base 1. The annular water-blocking gap 111 forms a continuous gap channel in the circumferential direction and is adjacent to the external environment. The bottom end of the inner skirt 61 of the rotating top cover 6 extends to the lower side of the outer side of the bearing outer seat 611 and is suspended and inserted in the annular water-blocking gap 111, so that the inner skirt 61 and the annular water-blocking flange 5143 form a non-contact labyrinth seal. Under this fit, the inner skirt 61 and the annular water-blocking flange 5143 are misaligned in the axial direction and maintain a distance in the radial direction, so that liquid entering from the opening of the mounting groove 11 needs to go through a deflection path before continuing to migrate inward. If external splashed liquid or condensate enters inward along the opening of the mounting groove 11, it will be sealed between the inner skirt 61 and the water-blocking flange. The relatively misaligned structure undergoes multiple directional turns and is affected by gravity, making it difficult to cross the maze path and enter the mounting groove 11. This provides dynamic protection for the electrical control components inside the mounting groove 11. At the same time, since the inner skirt 61 and the water-blocking flange maintain a floating gap, the maze seal does not rely on a contact-type pressing interface and will not introduce additional frictional resistance or wear sources. In some implementations, the lower end of the inner skirt 61 can form an inward or outward guiding edge, making it easier for droplets adhering to the surface of the inner skirt 61 to fall back to the opening area of ​​the mounting groove 11 under the action of gravity, thereby further reducing the retention of liquid in the maze channel.

[0038] A rotation sensor 8 is located at the relative motion interface between the rotating top cover 6 and the display interaction unit 5 and is connected to the control motherboard 7. It is used to output an adjustment signal in response to the rotation of the rotating top cover 6. In this embodiment, the rotation sensor 8 can be installed in the sensor slot 513 of the fixed support 51 and form a relative motion relationship with the corresponding trigger structure of the rotating top cover 6 in the radial or axial direction. When the rotating top cover 6 rotates around the central axis, the trigger structure changes position relative to the rotation sensor 8, thereby outputting an adjustment signal related to the rotation direction and rotation displacement. The adjustment signal is processed by the control motherboard 7 and used for subsequent adjustment and control of the fluid actuator 3. Furthermore, in some implementations, the corresponding triggering structure may be a circumferential periodic structure, a magnetic structure, or an optical shielding structure formed on the rotating top cover 6 or the inner skirt 61, and the rotation sensor 8 may be a detection structure sensitive to circumferential changes, thereby continuously generating pulse sequences or level change signals when the rotating top cover 6 undergoes stepless rotation; in other implementations, the rotation sensor 8 may distinguish the rotation direction output, enabling the control motherboard 7 to determine the rotation direction based on the phase relationship or change trend of the signal, and further combine it with the rotation displacement to determine the adjustment amplitude.

[0039] like Figure 3 and Figure 10 As shown, the inner cavity of the faucet base 1 below the sealing partition 514 forms a receiving cavity 12. The receiving cavity 12 serves as a centralized arrangement space for the liquid inlet pipeline 2 and the fluid execution unit 3. Its lower and side parts can form a continuous transition inner wall according to the outer curved surface of the faucet base 1, so as to reserve assembly margin for the bending transition of each pipeline, valve body installation and local maintenance. In this embodiment, the liquid inlet pipe 2 includes a cold water inlet pipe 21, a hot water inlet pipe 22, and a soda water inlet pipe 23. The three pipes can converge along one side of the faucet base 1 and enter the accommodating cavity 12 through the pipe inlet 13. In order to make the pipe introduction process more regular, the pipe inlet 13 can cooperate with the fixed sleeve 24 to form a "bundled tube" introduction structure. That is, before entering the accommodating cavity 12, the cold water inlet pipe 21, the hot water inlet pipe 22, and the soda water inlet pipe 23 are constrained by the fixed sleeve 24 to be relatively stable in parallel or bundled directions, thereby reducing the free swing of the pipes in the accommodating cavity 12, avoiding interference and friction with the inner wall of the accommodating cavity 12 or the fluid actuator 3, and reducing the fatigue risk caused by repeated start-stop and water hammer pulsation. After entering the accommodating cavity 12, the ends of the three pipelines can be arranged toward the corresponding interfaces of the fluid execution unit 3, so that the cold water inlet pipe 21, the hot water inlet pipe 22 and the soda water inlet pipe 23 form a relatively clear partitioned direction on the geometric path, avoiding cross-entanglement and facilitating subsequent assembly, positioning and maintenance disassembly.

[0040] The fluid actuator 3 includes a multi-way electrically controlled valve assembly. The multi-way electrically controlled valve assembly can be implemented as an integrated valve group, forming valve control channels corresponding to the cold water inlet pipe 21, hot water inlet pipe 22, and soda water inlet pipe 23 respectively within the same assembly, and forming a confluence channel connected to the liquid outlet terminal 4 on the outlet side of the valve control channel; or it can be implemented by combining and installing multiple electrically controlled valves in the accommodating cavity 12, with the inlet of each electrically controlled valve connected to the cold water inlet pipe 21, hot water inlet pipe 22, and soda water inlet pipe 23 respectively, and the outlet side of each electrically controlled valve connected to the liquid outlet terminal 4 through the confluence structure inside or outside the assembly. The control motherboard 7 is connected to the fluid actuator 3 and configured to receive touch commands and adjustment signals. When the touch command is used to switch the liquid dispensing mode, the control motherboard 7 achieves valve combination switching by controlling the on / off state of the multi-way electronically controlled valve assembly. For example, in the soda water independent dispensing mode, the control motherboard 7 controls the valve control channel corresponding to the soda water inlet pipe 23 to be in the conducting state, while controlling the valve control channels corresponding to the cold water inlet pipe 21 and the hot water inlet pipe 22 to be in the closed state, so that the fluid only enters the multi-way electronically controlled valve assembly along the soda water inlet pipe 23 and flows through its junction. The water is directed to the outlet terminal 4, thus achieving independent output of soda water. In the hot and cold mixing mode, the main control board 7 controls the valve control channels corresponding to the cold water inlet pipe 21 and the hot water inlet pipe 22 to be open and adjusts the ratio according to the preset logic, so that the cold water and hot water merge at the confluence channel of the multi-way electronically controlled valve assembly and enter the outlet terminal 4. In the mode that requires soda water to be mixed and output, the valve control channel corresponding to the soda water inlet pipe 23 is opened simultaneously on the basis of the above-mentioned hot and cold channels being open, so that the soda water and cold / hot water are combined before entering the outlet terminal 4. Furthermore, when the adjustment signal is used to adjust the discharge parameters in the current discharge mode, the control motherboard 7 can achieve continuous adjustment by controlling the opening of the multi-channel electronically controlled valve assembly: for example, the relative opening change of cold / hot water can achieve continuous change of flow mixing ratio, the synchronous opening change of each channel can achieve continuous change of total flow, and in the soda water related mode, the continuous adjustment of the opening of the soda water channel can achieve continuous change of soda water discharge intensity within a controllable range; the above opening control can be achieved by continuous drive of proportional valve, or by adjusting the duty cycle or equivalent drive amount of the electronically controlled valve to achieve equivalent stepless control, so that the adjustment signal output by the control motherboard 7 is mapped to a predictable change in valve orifice flow capacity on the fluid side.

[0041] The liquid outlet terminal 4 is mounted on the faucet base 1 and connected to the liquid inlet pipe 2. The liquid outlet terminal 4 includes a tubular liquid outlet 41 and a manifold adapter 42 inserted into the tubular liquid outlet 41. The manifold adapter 42 is used to establish a coaxially guided liquid outlet path between the manifold outlet of the multi-way electronically controlled valve assembly and the tubular liquid outlet 41, and can form a relatively smooth transition flow channel inside to reduce local eddies and energy loss. A second sealing ring 43 is provided between the outer peripheral wall of the manifold adapter 42 and the inner peripheral wall of the tubular liquid outlet 41. The second sealing ring 43 forms a continuous sealing boundary in the circumferential direction, so that after the manifold adapter 42 is inserted into place, it elastically seals the mating gap in the radial direction, thereby achieving a stable sealing connection at the liquid outlet terminal 4 and suppressing micro-leakage caused by vibration or pressure pulsation. At the same time, the elastic pre-tightening of the second sealing ring 43 can compensate for machining and assembly tolerances, so that the manifold adapter 42 maintains axial positioning stability in the inserted state. Combining the liquid outlet 41 forming a liquid outlet axis along the liquid outlet direction, and the preset obtuse angle formed between the liquid outlet axis and the central axis of the display interaction unit 5, the angle in this embodiment is 135 degrees. This means that the circular screen 52 is tilted at 45 degrees in the installation posture. When the liquid outlet terminal 4 is installed with the liquid outlet axis vertically downward, the central axis of the display interaction unit 5 is tilted relative to the vertical direction, making the display interface more conducive to observation and operation. In this posture, the user can complete the reading and touch operation of the display interface near the line of sight during water collection. At the same time, the user can manually apply a rotation adjustment action to the rotating cover 6, and control the main board 7 accordingly to perform mode switching and opening adjustment of the multi-way electronic control valve assembly, so that the three liquid inlet pipes 2 in the accommodating cavity 12 are connected to the liquid outlet terminal 4 with corresponding flow ratios in different liquid outlet modes and output stably.

[0042] During user operation, the user first performs a touch operation on the touch-sensitive area of ​​the display interaction unit 5 to select or switch the target liquid dispensing mode. After receiving the touch command, the control motherboard 7 controls the fluid execution unit 3 to complete the valve circuit switching corresponding to the target liquid dispensing mode, so that the channel in the liquid inlet pipe 2 corresponding to the target liquid dispensing mode is selected and connected to the liquid dispensing terminal 4. At the same time, the control motherboard 7 determines the corresponding adjustable controllable parameter as the liquid dispensing temperature parameter or the liquid dispensing flow rate parameter under the target liquid dispensing mode. Subsequently, the user holds the rotating cover 6 and rotates it relative to the display interaction unit 5. The rotation sensor 8 detects the rotation of the rotating cover 6 in real time, identifies the rotation direction and rotation displacement, and outputs a signal corresponding to the rotation direction and rotation displacement. The control motherboard 7 analyzes the signal to generate a stepless adjustment signal containing direction information and magnitude information. After the control board 7 generates a stepless adjustment signal, the control board 7 drives the fluid actuator 3 to perform bidirectional stepless adjustment on the inlet pipe 2 based on the stepless adjustment signal: when the adjustable control parameter is the outlet temperature parameter, the control board 7 executes the ratio adjustment logic, determines the increase or decrease trend of the flow mixing ratio according to the rotation direction, and determines the change range of the flow mixing ratio according to the rotation displacement, thereby achieving continuous change of outlet temperature by steplessly adjusting the relative flow capacity of cold water inlet pipe 21 and hot water inlet pipe 22; when the adjustable control parameter is the outlet flow rate parameter, the control board 7 executes the opening adjustment logic, determines the increase or decrease trend of the flow opening according to the rotation direction, and determines the change range of the flow opening according to the rotation displacement, thereby continuously adjusting the flow capacity of the currently selected valve path to change the outlet flow rate.

[0043] Through the above process, after the user completes the touch selection of the target liquid dispensing mode, they can continuously adjust the current liquid dispensing parameters by rotating the top cover 6 while keeping the liquid dispensing mode unchanged. The rotation direction and rotation displacement correspond to the parameter change direction and change range, respectively, thereby ensuring that the adjustment process has consistent interactive logic and predictable control response.

[0044] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
