Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble liquid generating devices struggle to produce a large amount of microbubbles and ultrafine bubbles that are effectively mixed and dissolved in the liquid.
Innovation Solution
A bubble liquid generating nozzle with a tubular body, a closing body, and a liquid guide formed in a three-dimensional shape, featuring an uneven surface with convex and concave portions, which creates a liquid flow path that enhances bubble formation and mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a liquid throttle hole is used to eject liquid and mix with air, then microbubbles can be generated, but the amount of microbubbles and ultrafine bubbles mixed and dissolved in the liquid is insufficient
Solution Approach 1:
The liquid guide features an uneven surface with multiple convex portions and concave portions that create a porous-like structure for liquid flow. This uneven surface generates turbulence and enhances mixing between liquid and air, producing a large amount of microbubbles and ultrafine bubbles that become dissolved in the liquid, thereby resolving the contradiction between bubble quantity and generation efficiency
Solution Approach 2:
The liquid guide is designed with a three-dimensional curved shape including convex and concave portions rather than a straight cylindrical form. This curvature creates complex flow patterns that enhance liquid-air mixing efficiency, generating abundant microbubbles and ultrafine bubbles while maintaining high productivity in the bubble liquid generation process
2Quantity of substance
If a simple liquid flow path is used, then the device structure is simple, but it cannot generate a large amount of microbubbles and ultrafine bubbles
Solution Approach 1:
The liquid guide incorporates localized uneven surfaces with convex and concave portions at specific locations within the flow path. These local structural variations create turbulence and enhance bubble generation without requiring complex overall device architecture. The simple cylindrical housing remains unchanged while the localized modifications to the liquid guide structure provide the necessary complexity to generate large amounts of microbubbles and ultrafine bubbles
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 nozzle effectively generates and ejects a bubble liquid with a large amount of microbubbles and ultrafine bubbles, forming a soft annular liquid film that can be used to effectively remove dirt and germs.
Implementation Method 1
The liquid guide is mounted in the liquid jetting hole so as to form a liquid flow path between the uneven surface and the inner peripheral surface. The liquid flows along the uneven surface, creating turbulence that generates microbubbles and ultrafine bubbles.
Implementation Method 2
mixes the liquid with air on a jetting side of the liquid throttle hole to generate microbubbles in the liquid flow path of the mixing adapter through pulverization (shear) of air
Implementation Method 3
causes a liquid to flow into the liquid throttle hole of the inlet adapter from a liquid inflow port and ejects the liquid into the liquid flow path of the mixing adapter

AI summary
The present invention includes: a nozzle main body (1), which includes a tubular body (8) and a closing flat plate (9) that closes one tube end (8A) of the tubular body (8), and in which an inflow space (δ) into which a liquid flows is formed in the tubular body (8); a liquid jetting hole (2) penetrating through the closing flat plate (9) and communicating to the inflow space (δ); and a liquid guide (23) arranged in the liquid jetting hole (2) from the inflow space (δ). The liquid guide (23) is mounted in the liquid jetting hole (2) from a conical upper surface (23A) so as to form a liquid flow path (ε) between the uneven surface of the conical side surface (23C) and a conical inner peripheral surface (2a) of the liquid jetting hole (2).
