Electrolytic Microbubble Generation Without High-Pressure Pumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micro-bubble generating devices require a separate device for high-pressure gas and liquid injection, leading to a large and complex system.
Innovation Solution
A micro-bubble generating system that uses an electrolytic bath to generate primary bubbles through electrolysis, which are then pulverized by a venturi structure to produce smaller secondary micro-bubbles, eliminating the need for external high-pressure pumps and enabling system miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate high-pressure pump is used to inject gas and liquid simultaneously, then micro-bubbles can be generated, but the system size becomes large and complexity increases
Solution Approach 1:
The patent combines the gas injection function and liquid circulation function into a single micro-bubble generation chamber. The gas injection hole is integrated directly into the chamber structure, eliminating the need for separate high-pressure pumps and complex injection systems. This merging of functions reduces system complexity while maintaining reliable micro-bubble generation.
Solution Approach 2:
The system uses the liquid circulation pump to serve dual purposes: circulating liquid through the system and providing the liquid component for micro-bubble generation. The gas is injected through a built-in hole in the chamber rather than requiring a separate gas injection system. This self-service approach eliminates auxiliary high-pressure equipment and simplifies the overall system structure.
2Reliability
If separate devices are used for gas and liquid injection, then micro-bubbles can be generated, but product cost increases
Solution Approach 1:
The patent integrates the gas injection hole directly into the micro-bubble generation chamber structure, combining what would otherwise require separate gas injection equipment and liquid circulation equipment into a single integrated unit. This reduces the number of components that need to be manufactured, assembled, and maintained, thereby reducing overall product cost while maintaining reliable micro-bubble generation capability.
3Reliability
If separate high-pressure equipment is connected to the micro-bubble generating system, then gas and liquid can be injected simultaneously, but the system cannot be installed in home appliances
Solution Approach 1:
The system uses existing household equipment (liquid circulation pump) to provide liquid flow for micro-bubble generation, and incorporates a simple gas injection hole in the chamber rather than requiring external high-pressure gas equipment. This self-service approach eliminates the need for large external equipment, reducing system volume to a size suitable for installation in home appliances like water purifiers and refrigerators while maintaining micro-bubble generation capability.
