Pull-Out Faucet Spray Head With Magnetic Water Flow Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pull-out faucets are inconvenient to turn on/off, and infrared sensor faucets have a limited sensing range, making it difficult to control continuous water flow, especially in kitchen settings.
Innovation Solution
A pull-out spray faucet with a spray head connected to a pull-out hose and a sensor trigger, featuring a solenoid valve and sensor switch, which allows water to flow when the spray head is pulled away from its initial position, using magnetic induction technology for activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical handle is used to turn on/off the faucet, then the structure is simple and reliable, but the convenience of operation is poor
Solution Approach 1:
The patent replaces the traditional mechanical handle switching system with a sensor-based automatic control system. The sensor trigger detects the user's hand approach and automatically activates the solenoid valve to control water flow, eliminating the need for manual handle operation and significantly improving ease of use.
Solution Approach 2:
The faucet system performs automatic detection and activation without requiring manual intervention. The sensor trigger autonomously detects when a user approaches and automatically opens the valve, allowing the system to serve itself by eliminating the need for manual handle operation.
2Ease of operation
If an infrared sensor is used to turn on/off the faucet, then the convenience of operation is improved, but the sensing range is small and cannot maintain continuous water flow
Solution Approach 1:
The patent employs a pull-out spray mechanism that dynamically changes the water delivery system. When the spray head is pulled out, the sensor trigger is activated and maintains continuous water flow through the extended hose, allowing the system to adapt between different operational states (fixed vs. extended position) to ensure reliable continuous flow.
Solution Approach 2:
The pull-out hose acts as an intermediary element that extends the sensing and water delivery range. When pulled out, it physically moves the spray head away from the faucet body, allowing the sensor trigger to maintain detection and control over an extended distance, ensuring continuous water flow capability.
3Adaptability or versatility
If the spray head is pulled out to extend water delivery range, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The pull-out spray head serves multiple functions: it extends the water delivery range for versatile use, activates the sensor trigger for automatic control, and can be retracted to a compact position when not in use. This multi-functionality justifies the added complexity by providing both extended range and automatic operation capabilities.

AI summary
A pull-out spray of a pull-out faucet includes a spray head connected to a pull-out hose of the pull-out faucet and a sensor trigger fitted to a faucet body of the pull-out faucet. The spray head includes a spray head body, a solenoid valve, and a sensor switch controlled by the sensor trigger. The solenoid valve and the sensor switch are fitted to the spray head body. The solenoid valve is electrically connected to the sensor switch. The solenoid valve controls the spray head body to spray water or not according a control signal of the sensor switch. The spray head is controlled to spray water by pulling the spray head, thereby improving the use of the pull-out faucet.
