Device for generating water with air bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for generating water with air bubbles fail to effectively control air inflow, resulting in large bubbles rather than high-density micro-bubbles, leading to a poor user experience.
Innovation Solution
A device comprising a flow divider, mixer, and water outlet cover, where the flow area of second water inlet holes is larger than first water inlet holes, creating a negative pressure that automatically controls air inflow through an air intake runner, and a filter screen assembly to produce micro-bubbles by circulating water and air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the flow area of second water inlet holes is increased to improve water flow, then water flow is improved, but air inflow control becomes difficult resulting in large bubbles
Solution Approach 1:
The water inlet system is segmented into two distinct sets of holes: first water inlet holes for air intake and second water inlet holes for water supply. This segmentation allows independent optimization of air and water flow paths, enabling the second holes to have larger flow area while the first holes control air intake precisely, resolving the contradiction between water flow improvement and bubble size control.
Solution Approach 2:
Different regions of the flow divider are assigned different functional qualities: the first water inlet holes are positioned and sized for optimal air intake, while the second water inlet holes are designed with larger flow area for water supply. This local differentiation of hole functions and dimensions enables both improved water flow and precise bubble size control to coexist.
2Manufacturing precision
If manual adjustment of air inflow is implemented, then air inflow can be controlled, but user convenience deteriorates due to manual operation requirements
Solution Approach 1:
The device achieves self-service air inflow control through the natural interaction between water flow and air intake. The first water inlet holes automatically draw in air based on water flow conditions, and the second water inlet holes deliver water to mix with the air. This self-regulating mechanism eliminates manual adjustment requirements while maintaining precise control over the air-water mixing process and bubble formation.
3Manufacturing precision
If hot water is used to generate micro-bubbles through temperature increase, then micro-bubble generation is improved, but energy consumption increases and limits normal temperature water usage
Solution Approach 1:
The patent replaces the thermal mechanism (heating water to reduce solubility) with a mechanical mechanism (controlled air injection through specifically designed inlet holes). The first water inlet holes introduce air directly into the water flow, and the second water inlet holes facilitate mixing, creating micro-bubbles through mechanical agitation and pressure differential rather than thermal effects. This substitution allows micro-bubble generation in normal temperature water, eliminating the energy consumption and temperature constraints of thermal methods.
