Pull-out Faucet Lock Head Sealing Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pull-out faucets face issues with sealing and durability due to friction and wear between the pull-out head and the pipe, especially from frequent opening and closing of the water flow.
Innovation Solution
The improved pull-out faucet design includes a lock head and flexible pull-out pipe with a spring, featuring multiple sealing rings (four in total) that are fixed to the lock head, enhancing sealing performance and reducing friction and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pull-out faucet structure is used, then the device is simple in structure, but the sealing performance deteriorates due to friction and wear between pull-out head and pipe
Solution Approach 1:
The pull-out faucet is divided into multiple functional components: pull-out head, lock head, flexible pull-out pipe, spring, and pipe connector. This segmentation allows each component to perform its specific function independently, with the lock head and sealing rings providing sealing without requiring the pull-out head to directly contact the pipe, thus resolving the contradiction between simple structure and sealing performance.
Solution Approach 2:
The lock head acts as an intermediary component between the pull-out head and the pipe. It provides a sealing surface for the sealing rings, preventing direct contact between the pull-out head and pipe. This intermediary structure maintains sealing performance while keeping the overall device structure relatively simple.
2Duration of action of moving object
If frequent opening and closing of water flow occurs, then the faucet is used intensively, but friction and wear increase leading to reduced durability
Solution Approach 1:
The lock head with sealing rings serves as an intermediary that prevents direct friction between the pull-out head and pipe. During frequent opening and closing operations, the sealing rings contact the lock head instead of the pipe, significantly reducing wear on critical components and extending the faucet's lifespan.
Solution Approach 2:
The flexible pull-out pipe with spring provides a flexible connection that accommodates movement during frequent opening and closing. This flexibility reduces stress and friction on rigid components, thereby reducing wear and extending durability.
3Ease of operation
If pull-out head directly contacts pipe for control, then the operation is direct, but excessive force is required and sealing deteriorates
Solution Approach 1:
The lock head acts as a mediator that provides a sealing surface for the pull-out head to contact during operation. Users can operate the faucet by moving the pull-out head along the lock head without requiring excessive force, while the sealing rings maintain sealing performance. This resolves the contradiction between ease of operation and sealing reliability.
4Reliability
If simple connection structure is used, then manufacturing is easier, but sealing performance and pressure resistance are insufficient
Solution Approach 1:
The connection structure is segmented into lock head, sealing rings, flexible pull-out pipe, and pipe connector. Each component can be manufactured separately using standard processes, then assembled together. This segmentation achieves good sealing and pressure resistance without significantly increasing manufacturing complexity, as each component remains relatively simple to produce.

AI summary
This invention relates to an improved pull-out water pipe technology, specifically disclosing a pull-out faucet. The pull-out faucet comprises a switch valve, an outer pipe, and a pull-out head. The front end of the outer pipe is equipped with the pull-out head, while the rear end is securely connected to the outlet of the switch valve. Inside the outer pipe, there are a lock head and a flexible pull-out pipe with a spring. The rear end of the flexible pull-out pipe has a pipe connector, which passes through the lock head to connect to the pull-out head. The outer wall of the pipe connector fits into the gap between the inner wall of the outer pipe. The outer wall of the lock head has a first sealing ring and a second sealing ring positioned between the lock head and the outer pipe. There is a third sealing ring and a fourth sealing ring between the outer wall of the flexible pull-out pipe and the lock head. All four sealing rings are relatively fixed to the lock head. This invention improves the design of traditional pull-out faucets, enhancing their sealing and durability, making them more suitable for various applications.
