Solution Overview
Problem
Existing bubble liquid generating nozzles struggle to produce a bubble liquid with a large amount of microbubbles and ultrafine bubbles, as they are limited in their ability to mix and dissolve these bubbles effectively.
Innovation Solution
A bubble liquid generating nozzle design featuring a nozzle main body with conical liquid jetting holes and a liquid guide body with conical liquid guides, forming an annular liquid flow path to enhance the mixing and dissolution of microbubbles and ultrafine bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional spray nozzle is used to apply liquid, then the liquid is dispersed, but large droplets are generated causing uneven coating and poor quality
Solution Approach 1:
The liquid flow path is divided into multiple segmented channels (first liquid flow path and second liquid flow path) within the nozzle. This segmentation allows the liquid to be distributed through multiple smaller openings rather than a single large opening, preventing large droplet formation and ensuring uniform coating application.
2Ease of manufacture
If the nozzle structure is simplified, then manufacturing is easier, but clogging occurs due to insufficient liquid supply or improper flow distribution
Solution Approach 1:
Different regions of the nozzle are designed with different structural characteristics. The nozzle includes specific flow distribution structures and channel configurations in critical areas to ensure proper liquid flow distribution and prevent clogging, while other areas maintain simpler structures for ease of manufacture.
Solution Approach 2:
The nozzle is pre-filled with liquid before operation begins. This preliminary action ensures that the liquid supply system is already primed and flowing correctly when the coating process starts, preventing air locks and ensuring immediate proper flow distribution without clogging.
3Manufacturing precision
If liquid supply is increased to improve coating coverage, then coating quality improves, but liquid waste increases
Solution Approach 1:
The nozzle design incorporates flow distribution structures that automatically regulate liquid flow based on the actual coating needs. The segmented liquid flow paths and flow control structures ensure liquid is distributed only where needed and in the precise amount required, providing inherent feedback control that prevents over-application and waste.
Solution Approach 2:
Instead of supplying excessive liquid to all areas uniformly, the system applies liquid partially and selectively to only those areas that require coating. The segmented flow paths enable precise local control, applying just enough liquid where needed rather than overwhelming the entire surface.

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 for efficient ejection.
Implementation Method 1
a bubble liquid is supplied to a coating target
Implementation Method 2
liquid is not sufficiently supplied, or the liquid is not properly distributed, thereby clogging occurs

AI summary
The present invention provides a bubble liquid generating nozzle capable of generating (producing) and ejecting a bubble liquid in which a large amount of microbubbles and a large amount of ultrafine bubbles are mixed and dissolved. 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 jetting hole (2) is formed in a shape of a conical hole. The liquid guide (23) is formed in a conical shape. A conical side surface (23C) of the liquid guide (23) is formed in a shape of an uneven surface on which a convex portion (31) and a concave portion (32) are arranged. 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).
