Peristaltic Pump Hose Channels for Electrohydrodynamic Atomizer Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrohydrodynamic atomization processes, particularly for care products like sunscreen, individual nozzles often clog, leading to an additional volume flow being applied to other open nozzles, compromising the quality of the atomization process.
Innovation Solution
A pump system with multiple hose channels, each connected to a separate atomizer nozzle, ensures that each nozzle receives a dedicated fluid supply, allowing for forced fluid flow that prevents clogging and maintains consistent volume flow, using a hose package with individual hose channels and pump rotors to manage the fluid delivery efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single hose channel is used to supply multiple nozzles, then the device complexity is reduced, but nozzle clogging occurs and atomization quality deteriorates
Solution Approach 1:
The single hose channel is divided into multiple separate hose channels, with each channel dedicated to supplying a specific nozzle. This segmentation prevents fluid from one nozzle from entering another nozzle, eliminating the clogging problem while maintaining manageable device complexity through systematic organization of the multiple channels.
2Reliability
If multiple separate hose channels are used for each nozzle, then nozzle clogging is prevented, but the device complexity increases
Solution Approach 1:
Multiple individual hose channels are nested within a single integrated hose assembly structure. The hose channels are arranged in parallel and bundled together, allowing each nozzle to have its dedicated channel while the overall assembly maintains a compact, organized form factor that minimizes the increase in device complexity.
3Productivity
If fluid flow is forced through clogged nozzles, then the pump volume flow increases to compensate, but the atomization quality deteriorates
Solution Approach 1:
The system prevents clogging from occurring in the first place by providing dedicated hose channels for each nozzle, ensuring that fluid is delivered cleanly to each nozzle opening. This preliminary prevention eliminates the need for compensatory volume flow increases and maintains consistent, high-quality atomization throughout operation.
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
This solution ensures reliable electrohydrodynamic atomization by preventing nozzle clogging and maintaining consistent fluid flow to each nozzle, enhancing process reliability and allowing for finer atomization by creating a hydraulically generated free jet that interacts with electrohydrodynamic forces outside the nozzle, improving the atomization effect.
Implementation Method 1
Peristaltic pumps, also known as rotary pumps or hose pumps, are also known from the prior art. These pumps operate on the principle of a positive displacement pump, propelling a fluid forward through the mechanical deformation of a hose section.
Implementation Method 2
the fluid is then subjected to a high voltage to effect electrohydrodynamic atomization
