Faucet Body Mixing Chamber Layout for Stable Outlet Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucets experience significant fluctuations in outlet water temperature due to direct collision of cold and hot water flows, and their manufacturing process is complex and costly.
Innovation Solution
A faucet body design featuring a left and right inlet seat connected by a horizontal pipe with a mixing chamber between them, where water flows from each inlet enter the mixing chamber before mixing, and the channels are formed by injection molding and core pulling, ensuring non-coplanar axes for the channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cold and hot water flows directly collide without a mixing chamber, then the structure is simple, but the outlet water temperature fluctuates significantly
Solution Approach 1:
A mixing chamber is introduced as an intermediary component between the cold and hot water channels. The mixing chamber allows the two water flows to mix gradually rather than colliding directly, stabilizing the outlet water temperature while maintaining structural simplicity through integrated molding.
2Manufacturing precision
If traditional gas-assisted injection molding and secondary injection molding are used, then the faucet body can be formed, but the forming process becomes complex and manufacturing costs increase
Solution Approach 1:
The patent combines multiple forming operations into a single injection molding process with core pulling. The left and right channels are formed integrally with the faucet body in one step, eliminating the need for gas-assisted injection molding, secondary injection molding, and mechanical processing, thereby simplifying the forming process while maintaining manufacturing precision.

AI summary
A faucet body includes a left inlet seat, a right inlet seat, and a horizontal pipe that connects the left inlet seat to the right inlet seat. Left and right valve chambers are provided inside the left and right inlet seats, respectively. The top of the left valve chamber is open, the left valve chamber is provided with a left valve chamber inlet and a left valve chamber outlet. The top of the right valve chamber is open, the right valve chamber is provided with a right valve chamber inlet and a right valve chamber outlet. A left channel, a right channel, and a mixing chamber are provided inside the horizontal pipe. The left channel and the right channel are curved channels. A first plane where an axis of the left channel is located is not coplanar with a second plane where an axis of the right channel is located.
