Bathtub Massage Nozzle Layout for Dense, Stable Bubble Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bathtub massage nozzles suffer from design limitations that result in diluted bubbles, intermittent flow, and uneven bubble distribution, leading to a suboptimal massage experience due to the close arrangement of the water and air inlets, which affects bubble stability and coverage.
Innovation Solution
A bathtub massage nozzle design with a staggered arrangement of the water and air inlets, forming a closed air cavity with sealing rubber rings, allowing for a sealed air path and controlled bubble formation, enhanced by a cam structure for easy disassembly and interchangeable nozzle cores for personalized massage options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the water inlet and air inlet are arranged close together in the traditional nozzle design, then the device structure is compact and simple, but the bubble generation effect is poor and bubble stability is reduced due to long gas injection path and bubble dilution
Solution Approach 1:
The patent changes the spatial arrangement from a close linear arrangement to a staggered arrangement where the air inlet is positioned closer to the water spraying end, creating a more optimized three-dimensional configuration that shortens the gas injection path while maintaining compact overall structure
2Device complexity
If the water inlet and air inlet are arranged close together, then the device structure is simple, but the bubble distribution is uneven and coverage is insufficient leading to weak massage effect in some areas
Solution Approach 1:
The staggered arrangement of inlets optimizes the spatial distribution of bubble generation points, enabling better coverage area and more uniform bubble distribution across the massage surface without significantly increasing structural complexity
3Reliability
If the air inlet is positioned far from the water spraying end, then the gas injection path is short and bubble dilution is reduced, but the overall device length increases and installation space requirement increases
Solution Approach 1:
The patent optimizes the positional relationship between water inlet and air inlet by arranging them in a staggered configuration, which shortens the effective gas injection path and improves bubble density while controlling the overall nozzle length through optimized spatial arrangement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances bubble density and stability, providing a more powerful and consistent massage experience with improved coverage, relieving muscle fatigue and stress, and offering a richer, denser bubble massage experience.
Implementation Method 1
The inner wall of the nozzle body and the nozzle core seat cooperatively form a closed air cavity between the sealing rubber rings... allowing for a sealed air path and controlled bubble formation

AI summary
A bathtub massage nozzle with switch function and good massage effect is provided. When in use, by aligning a core seat water inlet hole with a water inlet, water enters the nozzle core seat from the water inlet, and at the same time, the air is introduced from an air inlet, so that the air reaches a closed air cavity, and then the water flows out from the other end of the nozzle core seat to reach a gap between the nozzle core seat and the nozzle surface cover; at the same time, the gas is also discharged from an air outlet on the side of the nozzle core seat far away from the core seat water inlet hole through the closed air cavity, which reduces the dilution and loss of bubbles in the process of water flow transmission, and enables the water flow to form dense bubbles.
