[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] See Figure 1 , Figure 1 This is an application scenario diagram of a faucet with a built-in projector provided in an embodiment of this utility model. The faucet can be installed on a countertop and includes a sensor faucet body 110, a sensor 120, a projector 130, a flow sensor 140, a temperature sensor 150, a solenoid valve 160, and a power controller 170. The projector 130 and sensor 120 are installed inside the sensor faucet body 110, avoiding the problem of exposed components. Figure 2As shown, the power controller 170 is electrically connected to the sensor 120, projector 130, flow sensor 140, temperature sensor 150, and solenoid valve 160 to achieve coordinated control of each component. When the sensor 120 receives a user operation signal, the power controller 170 can control the solenoid valve 160 to open to start the faucet. At the same time, it receives the inlet water flow signal from the flow sensor 140 and the inlet water temperature signal from the temperature sensor 150, and sends the inlet water flow signal and inlet water temperature signal to the projector 130 so that the projector 130 can project the pressure and temperature information onto the projection area 180 (such as a wall) for the user to view in real time.

[0022] In one feasible embodiment, the power controller 170 integrates a central control module. This central control module can receive detection signals from the sensor 120, flow sensor 140, and temperature sensor 150, and control the on / off state of the solenoid valve 160 and the working state of the projector 130 based on the corresponding detection signals. By integrating the central control module, there is no need to set up an additional independent control unit, making the internal structure of the faucet more compact and the control response more timely.

[0023] In one feasible embodiment, the power controller 170 is configured with an AC power mode and a DC power mode; when the power controller 170 is connected to an AC power source, the projector 130 is in a continuous operating state; when the power controller 170 is connected to a DC power source, the projector 130 is in a standby state. This configuration can adapt to different usage scenarios, such as using AC mode to keep information constantly displayed in areas with mains power, and using DC mode to save power in temporary areas. In one feasible embodiment, when the power controller 170 is connected to a DC power supply and the faucet is running, the projector 130 can switch from a standby state to an operating state. By activating the projector only when water is used, DC power consumption can be further reduced, and battery life can be extended.

[0024] In one feasible embodiment, the water inlet end of the sensor faucet body 110 is provided with an installation interface adapted to the temperature sensor 150, and the temperature sensor 150 can be fixedly connected to the sensor faucet body 110 through the installation interface. Similarly, the water inlet end of the sensor faucet body 110 is provided with an installation interface adapted to the flow sensor 140, and the flow sensor 140 can also be fixedly connected to the sensor faucet body 110 through the corresponding installation interface.

[0025] In one feasible embodiment, the flow sensor 140 and the solenoid valve 160 are connected by a pipe, the inner diameter of which matches the inner diameter of the interfaces of the flow sensor 140 and the solenoid valve 160. Matching pipe diameters reduces water flow resistance, ensures smooth water intake, and avoids water flow fluctuations caused by inconsistent pipe diameters, resulting in more accurate flow detection.

[0026] In one feasible embodiment, the power controller 170 is integrated into a mounting cavity inside the sensor faucet body 110. The mounting cavity is provided with wiring holes for wires to pass through, allowing wires connecting various components to pass through. The mounting cavity protects the power controller 170 from water flow and moisture, while the wiring holes make the internal wiring neater and facilitate future maintenance.

[0027] In one feasible embodiment, sensor 120 is an infrared sensor, with its sensing window facing the water outlet of the faucet body 110. This orientation accurately captures the user's hand approaching the faucet, avoiding false triggering or non-triggering due to sensing angle deviation, thus improving the user experience.

[0028] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present utility model.
