Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microbubble generation devices for shower applications produce a very small volume of microbubbles, which limits their effectiveness in improving health and cleaning efficiency, as they struggle to generate bubbles with diameters less than 30 micrometers and achieve sufficient gas intake volume.
Innovation Solution
A swirling-type microbubble generation device with a cylindrical container body, a gas inlet, and a pressurized liquid inlet, featuring a cone-shaped wall and a cover body with a protruding pipe, optimized dimensions, and a disk-like housing with pores, to enhance gas intake and break-up into microbubbles, achieving a volume of 0.91 to 1.18 liters/min at 0.3 MPa water pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the volume of intake air is increased to generate more microbubbles, then the volume of microbubbles generated increases, but large bubbles are inevitably produced instead of microbubbles with diameter less than or equal to 30 micrometers
Solution Approach 1:
The device segments the bubble formation process into two stages: first, a large volume of air is introduced through the gas inlet to create abundant gas supply; second, the swirling liquid flow breaks this air into fine microbubbles with diameter ≤30 micrometers. This segmentation allows both high volume and small size to be achieved simultaneously.
Solution Approach 2:
The device uses hydraulic principles where pressurized liquid flows tangentially to create a swirling flow field. This hydraulic energy breaks up the introduced air into fine bubbles. The pneumatic aspect involves introducing air through the gas inlet and using the pressure differential and shear forces in the swirling flow to atomize the air into microbubbles.
2Quantity of substance
If conventional microbubble generation methods are used, then the device structure remains simple, but the volume of microbubbles generated is very small and functionality is not fully achieved
Solution Approach 1:
The device merges the gas introduction function and liquid swirling function into a single integrated chamber. The gas inlet and pressurized liquid inlet work together in the same space to generate microbubbles, eliminating the need for separate complex mechanisms while achieving high microbubble volume generation.
Solution Approach 2:
The swirling liquid flow automatically performs the bubble-breaking function without external intervention. The kinetic energy of the swirling flow self-generates the shear forces needed to atomize air into microbubbles, eliminating the need for additional mechanical breakers or complex control systems.

AI summary
A swirling-type microbubble generation device can discharge a swirling gas-liquid mixture containing a large volume of microbubbles into air in a concentrated manner by being placed in proximity to a jetting target, or in proximity to or in close contact with the jetting target in the air, or discharging such a mixture into water in a hot water tank, and discharging a swirling gas-liquid mixture containing a large volume of microbubbles as shower. The microbubble generation device includes a cylindrical container body that is closed at one end by a wall body and is open at the other end, a gas inlet provided in the wall body of the cylindrical container body on the one end side, and a pressurized liquid inlet provided in part of the circumferential wall of the cylindrical container body such that it is open in the direction of the tangent to the inner circumference thereof.
