Solution Overview
Problem
Conventional aerators are unable to generate fine bubbles at low water pressure and produce insufficient air-liquid mixtures with low air content, making it difficult to maintain bubble shape and achieve high air content with dense, fine bubbles.
Innovation Solution
A micro bubble generating device with a water inlet unit, water outlet unit, air inlet groove, and aerator mesh assembly that utilizes a Venturi effect and aerator meshes to increase bubble density and fineness, allowing air to mix with water under varying pressures, and includes a unique arrangement of passages and accommodating chambers to enhance air-liquid mixing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional aerator structure is used with high water pressure, then air-liquid mixture can be produced, but bubble volume is large and air content is low
Solution Approach 1:
The aerator is divided into multiple functional components: a Venturi tube for air suction, a mixing chamber for air-liquid mixing, and a mesh structure for bubble generation. This segmentation allows each component to perform its specific function optimally, enabling fine bubble generation without requiring high water pressure
Solution Approach 2:
The Venturi tube acts as an intermediary device that uses water flow to create negative pressure and suction air into the mixing chamber. This intermediary mechanism enables air intake without direct high-pressure injection, allowing fine bubble formation at lower water pressures
2Manufacturing precision
If conventional aerator structure is used, then air-liquid mixing can be achieved, but bubble fineness and density are insufficient
Solution Approach 1:
A mesh structure with fine pores is introduced into the mixing chamber. This porous material breaks the air-liquid mixture into numerous fine bubbles as the flow passes through it, significantly improving bubble fineness and density without requiring complex external mechanisms
Solution Approach 2:
The invention adds a spatial dimension to bubble generation by introducing a mesh structure that distributes the flow across multiple planes. This dimensional approach creates numerous small bubbles simultaneously, achieving fine bubble generation through geometric arrangement rather than complex dynamic control
3Use of energy by moving object
If water pressure is reduced, then energy consumption decreases, but conventional aerators cannot generate sufficient fine bubbles
Solution Approach 1:
The aerator design allows water flow itself to perform the air suction function through the Venturi effect, eliminating the need for external energy input or additional components. The water flow automatically draws air into the mixing chamber and creates fine bubbles through the mesh structure, achieving high bubble density at low energy consumption
