Extractable Faucet Structure With Separate Purified Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractable faucets cannot simultaneously provide purified and tap water without mixing, failing to meet user requirements for different water usage scenarios, such as cleaning and drinking, due to structural limitations.
Innovation Solution
An extractable faucet with a novel structure integrating a purified water line, featuring a faucet housing with a tubular cavity, an extractable head and conduit, a support for the purified water pipe, and a valve cartridge for separating the flow paths of tap-water and purified water, allowing independent control and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the faucet integrates both purified water and tap-water supply functions, then the user convenience and water usage versatility are improved, but the risk of water mixing and contamination increases
Solution Approach 1:
The internal flow paths are segmented into separate channels: a first flow path for purified water and a second flow path for tap-water. The valve cartridge contains separate valve bodies that independently control each flow path, preventing mixing while allowing both water types to be supplied through the same faucet outlet.
Solution Approach 2:
The valve cartridge acts as an intermediary control device between the water supply sources and the faucet outlet. It uses valve plates with flow guiding grooves to direct and separate the two water types, ensuring they remain distinct until discharge through the common outlet.
2Device complexity
If the faucet structure is simplified to a single outlet, then the device complexity is reduced, but the ability to provide separate purified and tap-water flows is compromised
Solution Approach 1:
The single faucet outlet serves multiple functions by receiving both purified water and tap-water through the same discharge opening. The valve cartridge enables this universal outlet to selectively supply different water types based on user needs, maintaining simplicity while achieving multi-functionality.
Solution Approach 2:
The faucet housing and outlet structure are merged into a single unified component that handles both water types. The internal valve system combines control mechanisms for both purified water and tap-water within one cartridge assembly, reducing the need for separate faucet bodies while maintaining separate flow paths.
3Reliability
If additional fixtures are added to provide purified water separately, then the drinking water safety is improved, but the device complexity and space requirement increase
Solution Approach 1:
The patent merges the purified water supply function and tap-water supply function into a single faucet assembly. Both water types are delivered through one faucet body with a unified outlet, eliminating the need for separate fixtures while maintaining drinking water safety through the integrated valve separation system.

AI summary
Disclosed herein is a faucet comprising a faucet housing configured as a tubular member with a cavity and a faucet body that includes a head and a conduit. A water inlet end of the head is connected to the conduit. A first support is received in the cavity and located in a water outlet end of the faucet housing. The head is freely received in the first support and a purified water pipe is embedded detachably into the first support. A mounting seat is configured to function as a water distributor and is detachably engaged with the faucet housing. A valve cartridge is received in the mounting seat and configured to control the shut off of the conduit and the purified water pipe, and to separate the flow path of the tap-water and the flow path the purified water.
