They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] like Figures 1-3As shown, a wireless touch controller according to this embodiment includes: a touch button 1 for receiving user touch operations; a touch sensor chip U2, whose signal input terminal is connected to the touch button 1, for detecting and outputting different control signals according to the duration of the touch operation, the control signals including at least a first control signal and a second control signal; a main control chip U1, whose signal input terminal is connected to the signal output terminal of the touch sensor chip U2, for receiving the control signals output by the touch sensor chip U2, the main control chip U1 generating a first wireless control command and a second wireless control command respectively based on the received first and second control signals; and a wireless communication module U3, which is communicatively connected to a water outlet device for wireless communication. The signal input terminal of module U3 is connected to the signal output terminal of the main control chip U1; the power supply unit provides operating power for the touch sensor chip U2, the main control chip U1, and the wireless communication module U3. The main control chip U1, the touch sensor chip U2, and the wireless communication module U3 are all components available on the market. The power supply unit can provide stable power to components such as button batteries and storage batteries to ensure system operation. The power supply unit can use existing mature voltage regulation circuits, such as using a CR2032 button battery as the power input. The positive terminal of the button battery is connected to the input terminal of a low dropout voltage regulator chip to stabilize the voltage to 3.3V. The regulated 3.3V is then supplied to the main control chip U1, the touch sensor chip U2, and the wireless communication module U3.

[0023] For example, when controlling the water temperature of a faucet with a fixed water output, the touch sensor chip U2 detects a short touch and sends a first control signal to the main control chip U1. The main control chip U1 generates a cold water start command and sends it to the water outlet device through the wireless communication module U3 to trigger cold water output. When the touch sensor chip U2 detects a continuous touch, it sends a second control signal to U1. The main control chip U1 generates a hot water start command and sends it to the water outlet device through the wireless communication module U3 to trigger hot water output. When using the device for the first time or when re-pairing is required, the user can press and hold the touch button 1 continuously. At this time, the long press time significantly exceeds the time threshold of normal operation. After the main control chip U1 detects the continuous touch signal, it enters the pairing mode. At this time, the wireless receiving module at the water outlet device end simultaneously activates pairing listening and searches for pairing request data frames containing device identification codes sent by the wireless communication module U3 in the 2.4G frequency band. When both parties complete key exchange and establish a stable communication link, pairing is successful.

[0024] Specifically, the touch sensor chip U2 is configured to output the first control signal when the touch duration of the touch button 1 is less than a time threshold; and to output the second control signal when the touch duration of the touch button 1 is greater than or equal to the time threshold. The time threshold is set according to human operating habits and the need to prevent accidental touches, and is usually configured through the internal register of the touch sensor chip U2 within the range of 0.5 seconds to 1.5 seconds. If the touch duration is less than the time threshold, it is judged as a short touch and the water outlet device triggers cold water output; if the touch duration reaches or exceeds the time threshold, it is judged as a long touch and the water outlet device triggers hot water output.

[0025] Specifically, it also includes a first indicator light L1 and a second indicator light L2. The anode of the first indicator light L1 is connected to the main control chip U1, and the cathode is connected to ground through a resistor R1. The anode of the second indicator light L2 is connected to the main control chip U1, and the cathode is connected to ground through a resistor R3. The main control chip U1 is configured to light up the first indicator light L1 when it receives a first control signal, and to light up the second indicator light L2 when it receives a second control signal. The first indicator light L1 and the second indicator light L2 are set to different colored LEDs, namely red or blue. When the touch button 1 is briefly touched, the first indicator light L1 lights up, and when the touch button 1 is long-pressed, the second indicator light L2 lights up.

[0026] Specifically, the touch sensor chip U2 is model TS01S, using an SOT23-6 six-pin package. Pin 1 of the touch sensor chip U2 is connected to the signal input terminal of the main control chip U1 and is connected to the power supply unit through resistor R2. Pin 2 of the touch sensor chip U2 is connected to the power supply unit and grounded via a parallel capacitor C1. Pin 3 of the touch sensor chip U2 is grounded via resistor R5. Pin 4 of the touch sensor chip U2 is connected to touch button 1 via a series resistor R4 and grounded via a parallel capacitor C2. Pin 5 of the touch sensor chip U2 is grounded. Pin 6 of the touch sensor chip U2 is grounded via capacitor C4. Resistor R2 acts as a pull-up resistor to prevent false triggering caused by interference and enhances signal strength. The signal driving capability is enhanced by capacitor C1 filtering out high-frequency noise from the power supply unit, preventing voltage fluctuations from causing malfunctions in the touch sensor chip U2, and improving anti-interference performance. Resistor R4 and capacitor C2 form an RC touch detection network. When the user touches touch button 1, the human body capacitance is superimposed on capacitor C2, changing the equivalent capacitance value of the RC network, thereby changing the oscillation frequency. Touch actions are identified by detecting frequency changes. At the same time, resistor R4 also limits current and suppresses static electricity, protecting the touch sensor chip U2 from damage. Capacitor C4 sets the reference frequency of the RC oscillator, converting the small capacitance changes caused by touch into measurable frequency offsets, enabling the touch sensor chip U2 to accurately distinguish touch events and their duration.

[0027] Specifically, the main control chip U1 is a microcontroller of model N76E003AT20. Pin 5 of the main control chip U1 is connected to the signal output terminal of the touch sensor chip U2 to receive control signals. Pin 9 of the main control chip U1 is connected to the power supply unit. Pin 7 of the main control chip U1 is grounded. Capacitor C3 is connected between pin 7 and pin 9 of the main control chip U1. Pin 20 of the main control chip U1 is connected to the first indicator light L1. Pin 17 of the main control chip U1 is connected to the second indicator light L2. Pins 11 to 16 of the main control chip U1 are connected to the corresponding signal terminals of the wireless communication module U3.

[0028] The wireless communication module U3 is a 2.4G wireless module of model NF-03. The power input terminal of the wireless communication module U3 is connected to the power supply unit and has capacitors C5 and C6 connected in parallel. The wireless communication module U3 is based on 2.4GHz. Operating in the ISM band, the wireless control commands received from the main control chip U1 are packaged into radio frequency data frames and sent to the paired water outlet device. Pin 1 of the wireless communication module U3 is connected to the power supply unit. Capacitors C5 and C6 are used to prevent high-frequency and low-frequency power supply noise, respectively, to ensure the stability of radio frequency transmission and the reliability of communication. Pin 2 of the wireless communication module U3 is grounded. Pin 3 of the wireless communication module U3 and pin 14 of the main control chip U1 are used to control the enable state of the wireless communication module U3. Pin 4 of the wireless communication module U3 and pin 11 of the main control chip U1 are used to select and control the communication state of the wireless communication module U3. Pin 5 of the wireless communication module U3 and pin 15 of the main control chip U1 are used to provide a serial communication clock signal. Pin 6 of the wireless communication module U3 and pin 12 of the main control chip U1 are used to receive control commands from the main control chip U1. Pin 7 of the wireless communication module U3 and pin 16 of the main control chip U1 are used to send relevant data to the main control chip U1. Pin 8 of the wireless communication module U3 and pin 13 of the main control chip U1 are used to send an interrupt request signal to the main control chip U1.

[0029] This technical solution also includes a housing 2. The main control chip U1, touch sensor chip U2, wireless communication module U3, and power supply unit are all disposed inside the housing. The touch button 1 is disposed on the surface of the housing. The light source portions of the first indicator light L1 and the second indicator light L2 are exposed on the surface of the housing 2. Through holes are opened on the housing 2 to allow the light source portions of the first indicator light L1 and the second indicator light L2 to pass through. Appropriate watertight measures are taken on the through holes and other splicing parts of the housing 2 to prevent water vapor from entering.
