Description

Technical Field

[0001] This utility model relates to the field of intelligent control technology, and more specifically, to an intelligent faucet control system based on multimodal interaction. Background Technology

[0002] With the rapid development of smart home technology, the intelligentization of bathroom products has become an industry trend. As an indispensable water-using terminal in daily life, the ease of use and level of intelligence of faucets directly affect the user experience. Traditional mechanical faucets are mainly controlled manually via knobs or wrenches, which suffers from inconvenience, cross-contamination, and water waste when adjusting water temperature.

[0003] With the development of technology, some smart faucets based on a single sensing mode have begun to emerge, such as those using infrared sensors to achieve automatic water dispensing and shutting off. These products improve hygiene and water conservation to some extent, but their functions are relatively limited, usually only able to perform fixed water dispensing / shutting operations, lacking flexible control dimensions (such as water temperature and water volume adjustment), and are easily affected by factors such as ambient light and objects accidentally obstructing the flow, leading to false triggering or malfunction.

[0004] In recent years, the popularization of the Internet of Things (IoT) and smart home concepts has made remote control of home appliances via mobile terminal (such as smartphone) apps a trend. However, relying solely on app control also has limitations: users need to carry their mobile devices and access the operating interface. When their hands are dirty or they are busy with kitchen chores, taking out their phones to perform multiple operations is cumbersome and cannot meet the need for immediate and convenient interaction.

[0005] For home users, especially those with children, there are higher requirements for faucet safety. Traditional faucets pose a risk of scalding if hot water flows directly out when turned on. At the same time, how to clearly and intuitively display the faucet's current operating status (such as water temperature and operating mode) and how to provide convenient after-sales service (such as product information inquiry and fault reporting) are aspects that current smart faucet product designs have not adequately considered. Utility Model Content

[0006] The technical problem this invention aims to solve is the lack of a comprehensive intelligent faucet control system in the prior art that can integrate multiple interaction modes, take into account the convenience of non-contact control and the accuracy of mobile terminal control, and integrate status display and safety protection functions. To overcome the above-mentioned deficiencies of the prior art, this invention provides an intelligent faucet control system based on multimodal interaction.

[0007] This utility model provides an intelligent faucet control system based on multimodal interaction, including a main control module, a Bluetooth communication module for receiving setting instructions from a mobile terminal, a gesture recognition module for collecting user gesture signals through non-contact sensing technology and parsing them into control instructions, and a display module for displaying the working status information of the faucet. The output of the gesture recognition module is electrically connected to the Bluetooth communication module, the Bluetooth communication module is connected to the main control module via serial communication, the main control module is electrically connected to the display module, and the main control module is electrically connected to the faucet motor through the drive module. The main control module is electrically connected to a button module, which includes a child lock button, a high-temperature pre-discharge button, a high-temperature QR code display button, a normal-temperature discharge button, a normal-temperature QR code display button, and a discharge button. The child lock button, the high-temperature pre-discharge button, the high-temperature QR code display button, the normal-temperature discharge button, the normal-temperature QR code display button, and the discharge button are all electrically connected to the main control module through a first resistor.

[0008] Compared with existing technologies, the intelligent faucet control system based on multimodal interaction proposed in this application has the following advantages: By integrating multiple interaction modes such as gesture recognition, Bluetooth remote control, physical buttons, and status display, a flexible, safe, and feature-rich intelligent faucet control system is constructed, achieving a complementarity between "contactless convenient operation" and "precise remote control." Users can achieve contactless quick switching and adjustment through gestures, avoiding cross-infection and providing intuitive operation; they can also personalize settings through mobile terminals to meet precise control needs; at the same time, the unique "child lock" and "high-temperature pre-discharge" functions effectively prevent the risk of scalding, while the "QR code display" button facilitates users to obtain product information or after-sales service, and the retention of physical buttons provides reliable traditional operation assurance for users unfamiliar with electronic devices, ultimately achieving a high degree of unity between intelligence, safety, and practicality.

[0009] In one possible implementation, the gesture recognition module is an infrared gesture control digital module of model BM32S3031-1.

[0010] In one possible implementation, the room temperature water dispensing button, the room temperature QR code display button, the water dispensing button, the child lock button, the high temperature pre-dispensing button, and the high temperature QR code display button are all touch buttons.

[0011] Compared with existing technologies, by setting all function buttons to touch, the product's hygiene, durability, and overall aesthetics are significantly improved while inheriting the intuitive operation logic of traditional buttons. The non-contact touch operation effectively avoids cross-infection of bacteria, making it especially suitable for bathroom environments. At the same time, it seamlessly integrates with the contactless interaction concept built by its gesture recognition module, forming a unified, modern, and easy-to-clean integrated panel design. This ensures ease of operation while greatly optimizing the user's health experience and the product's visual appeal.

[0012] In one possible implementation, the main control module is also electrically connected to an indicator light module for indicating whether the button module is activated. The indicator light module includes an LED driver chip, a child lock indicator light, a high-temperature pre-discharge indicator light, a high-temperature QR code display indicator light, a normal-temperature pre-discharge indicator light, a normal-temperature QR code display indicator light, and a water outlet icon indicator light. The child lock indicator light, high temperature pre-discharge indicator light, high temperature QR code display indicator light, normal temperature pre-discharge indicator light, normal temperature QR code display indicator light, and water outlet icon indicator light are all electrically connected to the LED driver chip through a third resistor. The LED driver chip is electrically connected to the main control module, and the LED driver chip is a TM1650 chip.

[0013] Compared with existing technologies, by introducing an indicator light module controlled by a dedicated LED driver chip, each touch button is equipped with a clear status indication, which greatly improves the intuitiveness and accuracy of human-computer interaction.

[0014] In one possible implementation, the main control module is electrically connected to a buzzer module for displaying whether the button module has been successfully triggered. The buzzer module includes a buzzer B1 and a transistor Q3. The positive terminal of the buzzer B1 is electrically connected to the power supply, the negative terminal of the buzzer B1 is electrically connected to the collector of the transistor Q3, the negative terminal of the buzzer B1 is electrically connected to the positive terminal of the diode D1, and the positive terminal of the buzzer B1 is electrically connected to the negative terminal of the diode D1. The emitter of the transistor Q3 is grounded, the base of the transistor Q3 is electrically connected to the main control module, and the base of the transistor Q3 is electrically connected to the emitter of the transistor Q3 through a resistor R8.

[0015] Compared with existing technologies, by adding a buzzer module driven by a transistor and equipped with a protection diode, the user operation is provided with immediate and clear auditory feedback. When the button module is successfully triggered, the buzzer emits a prompt sound, which complements the visual indicator light to form a complete audiovisual interaction loop. This effectively avoids accidental touches or operational uncertainties in multimodal interaction and enhances the sense of confirmation and responsiveness of the interaction.

[0016] In one possible implementation, the power supply terminal of the main control module is electrically connected to the power supply through a voltage regulator circuit, the voltage regulator circuit including a voltage regulator chip U2; the input terminal of the voltage regulator chip U2 is grounded through electrolytic capacitor E2, capacitor C8 and capacitor C9 respectively, the input terminal of the voltage regulator chip U2 is electrically connected to the power supply, the output terminal of the voltage regulator chip U2 is grounded through capacitor C6 and capacitor C7 respectively, and the output terminal of the voltage regulator chip U2 is electrically connected to the power supply terminal of the main control module.

[0017] Compared with existing technologies, by adopting a voltage regulator circuit composed of a dedicated voltage regulator chip and multi-capacitor filtering, a highly stable and clean DC power supply is provided to the main control module, which significantly improves the reliability and anti-interference capability of the entire control system.

[0018] In one possible implementation, the display module is an LCD screen.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-4 As shown in the figure, this application discloses an intelligent faucet control system based on multimodal interaction, including a main control module, a Bluetooth communication module for receiving setting instructions from a mobile terminal, a gesture recognition module for collecting user gesture signals through non-contact sensing technology and parsing them into control instructions, and a display module for displaying the working status information of the faucet.

[0025] By integrating Bluetooth communication, gesture recognition, display, and multi-functional button modules, a multi-modal interaction system is constructed to enhance the convenience, functionality, and safety of smart faucets. Users can remotely personalize settings via mobile devices or perform hygienic and intuitive operations through contactless gestures. The display module provides real-time feedback on key information such as water quality, while the button module, integrating child lock and QR code display functions, further enhances safety and ease of use, achieving an upgrade from simple mechanical control to intelligent, scenario-based, and user-friendly comprehensive management.

[0026] The serial communication connection between the Bluetooth communication module and the main control module is an existing technology.

[0027] In this embodiment, the gesture recognition module is an infrared gesture control digital module of model BM32S3031-1. Specifically, it can recognize gestures such as waving left, right, up, down, and hovering, as well as some custom gestures, and parse these gestures into corresponding control commands, such as: switch, water volume adjustment, water temperature switching, and other control commands.

[0028] The control commands parsed by the gesture recognition module are first transmitted to the Bluetooth communication module, and then transmitted to the main control module; or, the control commands parsed by the gesture recognition module are directly transmitted to the main control module.

[0029] The display module is an LCD screen. It can display the faucet's operating status, water quality information, interactive menus, water flow information, filter status, etc., in real time. This information visualization enhances the transparency and user-friendliness of the human-computer interaction.

[0030] The Bluetooth communication module is a CH592F model. It establishes bidirectional data communication with the user's mobile terminal (such as a smartphone), receives scenario-based setting commands from the mobile terminal, and allows users to preset and issue various water usage scenarios (such as drinking, tea brewing, and cleaning) via a mobile app. The system automatically executes predefined water output parameters according to the scenario, greatly enhancing the personalization and intelligence of the user experience.

[0031] Furthermore, control commands can be generated via NFC or voice and transmitted to the main control module to control the faucet motor to turn on and off.

[0032] In this embodiment, the room temperature water dispensing button, the room temperature QR code display button, the water dispensing button, the child lock button, the high temperature pre-dispensing button, and the high temperature QR code display button are all touch buttons.

[0033] By making all function buttons touch-sensitive, the product's hygiene, durability, and overall aesthetics are significantly improved while retaining the intuitive operation logic of traditional buttons. The non-contact touch operation effectively avoids cross-infection of bacteria, making it especially suitable for bathroom environments. At the same time, it seamlessly integrates with the contactless interaction concept built by its gesture recognition module, forming a unified, modern, and easy-to-clean integrated panel design. This ensures ease of operation while greatly optimizing the user's health experience and the product's visual appeal.

[0034] In this embodiment, the main control module is also electrically connected to an indicator light module for indicating whether the button module is activated. The indicator light module includes an LED driver chip, a child lock indicator light, a high temperature pre-discharge indicator light, a high temperature QR code display indicator light, a normal temperature pre-discharge indicator light, a normal temperature QR code display indicator light, and a water outlet icon indicator light. The child lock indicator, high temperature pre-discharge indicator, high temperature QR code display indicator, normal temperature pre-discharge indicator, normal temperature QR code display indicator, and water outlet icon indicator are all electrically connected to the LED driver chip through a third resistor. The LED driver chip is electrically connected to the main control module. The LED driver chip is a TM1650 chip.

[0035] By introducing an indicator light module controlled by a dedicated LED driver chip, each touch button is equipped with a clear status indication, greatly improving the intuitiveness and accuracy of human-computer interaction.

[0036] Users can clearly confirm whether a function is enabled (such as child lock), the current water dispensing mode (such as high temperature / normal temperature), or the QR code display status by observing the status of indicator lights (such as on / off and color), effectively avoiding accidental operation. At the same time, the use of dedicated driver chips such as TM1650 simplifies the load and circuit design of the main control module, improves system stability and response efficiency, and provides clear, immediate and reliable visual feedback in complex multimodal interactions.

[0037] In practical design, the child lock indicator light can be designed to light up blue when powered on and white when unlocked; the high-temperature pre-discharge water indicator light can be designed to be controlled by the child lock, lighting up blue when not unlocked and white when unlocked; the high-temperature QR code display indicator light can be designed to be controlled by the child lock, lighting up blue when not unlocked and white when unlocked; the normal temperature pre-discharge water indicator light can be designed not to be controlled by the child lock, lighting up white normally and blue after startup; the normal temperature QR code display indicator light can be designed to be controlled by the child lock, lighting up blue when not unlocked and white when unlocked; the water discharge icon indicator light can be designed not to be controlled by the child lock, lighting up white normally and blue after startup.

[0038] The main control module is electrically connected to a buzzer module used to display whether the button module has been successfully triggered.

The positive terminal of the buzzer B1 is electrically connected to the power supply, the negative terminal of the buzzer B1 is electrically connected to the collector of the transistor Q3, the negative terminal of the buzzer B1 is electrically connected to the positive terminal of the diode D1, and the positive terminal of the buzzer B1 is electrically connected to the negative terminal of the diode D1. The emitter of the transistor Q3 is grounded, the base of the transistor Q3 is electrically connected to the main control module, and the base of the transistor Q3 is electrically connected to the emitter of the transistor Q3 through a resistor R8.

[0039] By adding a buzzer module driven by a transistor and equipped with a protection diode, immediate and clear auditory feedback is provided to the user. When the button module is successfully triggered, the buzzer emits a prompt tone, complementing the visual indicator light to form a complete audiovisual interaction loop. This effectively avoids accidental touches or operational uncertainties in multimodal interaction, enhancing the sense of confirmation and responsiveness. The circuit design is simple and reliable. The diode eliminates the back electromotive force generated by the buzzer coil, protecting the driving transistor and improving the system's stability and lifespan.

[0040] The power supply terminal of the main control module is electrically connected to the power supply through a voltage regulator circuit, which includes a voltage regulator chip U2. The input terminal of the voltage regulator chip U2 is grounded through electrolytic capacitor E2, capacitor C8 and capacitor C9 respectively, and the input terminal of the voltage regulator chip U2 is electrically connected to the power supply. The output terminal of the voltage regulator chip U2 is grounded through capacitor C6 and capacitor C7 respectively, and the output terminal of the voltage regulator chip U2 is electrically connected to the power supply terminal of the main control module.

[0041] By employing a voltage regulator circuit composed of a dedicated voltage regulator chip and multi-capacitor filtering, a highly stable and clean DC power supply is provided to the main control module, significantly improving the reliability and anti-interference capability of the entire control system. This design effectively suppresses voltage fluctuations and various noise interferences at the power input terminal, ensuring that the main control module and its connected core units such as gesture recognition, display, and communication always operate at the rated voltage. This avoids program crashes, malfunctions, or performance degradation caused by power supply issues, fundamentally guaranteeing the long-term stable operation and service life of the smart faucet in complex power environments.
