Nested Waterway Joint Locking for High-Pressure Purifier Faucets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifiers face challenges in arranging multiple pipelines due to high water pressure, leading to frequent disconnection of double-layer joints.
Innovation Solution
A waterway transferring device with an anti-releasing mechanism, comprising a first and second anti-releasing member, prevents joint disconnection by rotating and abutting to inhibit rotation, and angled water inlet passages to prevent pipeline tangling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the double-layer joint structure is used to integrate purified water pipeline and water supply line, then the number of pipelines is reduced, but the joint easily releases due to high water pressure
Solution Approach 1:
The inner joint is nested within the outer joint, forming a double-layer tube structure where the inner joint extends in the outer joint. The inner joint connects to the first water inlet passage while the outer joint rotates to connect to the water outlet passage, creating an integrated pipeline system that reduces overall complexity while maintaining connection stability through the nested configuration.
Solution Approach 2:
The outer joint is designed to be rotatable relative to the inner joint, allowing dynamic adjustment and secure connection. The rotation mechanism enables the outer joint to be rotated to connect to the water outlet passage, creating a flexible yet stable connection that can accommodate installation variations while preventing premature release under water pressure.
2Ease of manufacture
If multiple pipelines are mounted independently for water purifier installation, then each pipeline can be installed separately, but the number of pipelines increases and arrangement becomes difficult
Solution Approach 1:
The invention merges the purified water pipeline and water supply line into a single integrated double-layer tube structure. The inner joint and outer joint are combined in one assembly, with the inner joint connecting to the first water inlet passage and the outer joint connecting to the water outlet passage, thereby reducing the total number of separate pipelines while maintaining installation flexibility through the rotatable connection mechanism.
3Ease of operation
If the outer joint is made rotatable for connection, then installation ease is improved, but the joint may rotate reversely and release under water pressure
Solution Approach 1:
The anti-releasing mechanism incorporates protrusions on the outer joint that engage with corresponding grooves on the inner joint before water pressure can cause reverse rotation. This preliminary anti-action prevents the outer joint from rotating reversely and releasing, while still allowing forward rotation during installation. The protrusions and grooves are positioned to provide immediate resistance against water pressure-induced reverse rotation.

AI summary
A waterway transferring device comprises a transferring body, a water outlet joint, and an anti-releasing mechanism. The transferring body comprises a first water inlet passage, a second water inlet passage, and a water outlet passage. The water outlet joint comprises an outer joint and an inner joint extending in the outer joint and connected to the first water inlet passage. The anti-releasing mechanism comprises a first anti-releasing member and a second anti-releasing member. When the outer joint is rotated to be connected to the water outlet passage, the first anti-releasing member and the second anti-releasing member are rotated relative to each other to be connected together, and when the outer joint is rotated reversely, the first anti-releasing member and the second anti-releasing member abut each other in an opposite direction to inhibit a rotation of the outer joint.
