Atomizer Core Inlet Structure for Leak-Controlled Aerosol Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers face issues with controlling the flow rate and pressure at the liquid inlet, leading to matrix liquid leakage without being atomized, which affects user experience and wastes matrix liquid.
Innovation Solution
An atomizer design with a liquid retaining structure on the sealing member partially blocks the liquid inlet, adjusting flow rate and pressure to match the atomization process, and includes liquid guide plates to direct atomized liquid to the atomizer core, reducing leakage and improving atomization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid inlet is fully open to allow sufficient liquid flow, then the atomization process can proceed, but excessive liquid flow rate and pressure cause matrix liquid to leak from the atomizer core into the exhaust port without being atomized
Solution Approach 1:
The liquid retaining structure is positioned specifically at the liquid inlet of the atomizer core to locally control liquid flow. This structure partially blocks the liquid inlet, creating different flow conditions at different locations: the blocked area reduces flow rate and pressure to prevent leakage, while the exposed area maintains sufficient flow for atomization. This local differentiation resolves the contradiction between preventing leakage and maintaining atomization efficiency.
Solution Approach 2:
The liquid retaining structure implements partial blocking of the liquid inlet rather than complete closure. By blocking only a portion (2/3 to 3/4 of the total area) of the liquid inlet, the structure reduces excessive liquid flow and pressure enough to prevent leakage while leaving sufficient flow (the exposed area) to maintain effective atomization. This partial action approach balances the conflicting requirements.
2Object-generated harmful factors
If the liquid inlet is partially blocked to reduce flow rate and pressure, then liquid leakage is prevented, but the flow rate and pressure may become insufficient for effective atomization
Solution Approach 1:
The liquid retaining structure creates localized flow control by blocking only a specific portion of the liquid inlet. The blocked area (2/3 to 3/4) reduces flow rate and pressure to prevent leakage, while the exposed area maintains sufficient flow for atomization. This spatial differentiation allows simultaneous achievement of leakage prevention and adequate atomization flow.
Solution Approach 2:
Instead of complete blocking, the liquid retaining structure implements partial blocking of the liquid inlet. This partial action reduces excessive flow and pressure enough to prevent leakage while preserving sufficient flow through the exposed area to maintain effective atomization, thus resolving the contradiction between leakage prevention and atomization efficiency.
3Quantity of substance
If the liquid inlet size is increased to improve liquid supply, then atomization can proceed, but the risk of liquid leakage increases
Solution Approach 1:
The liquid retaining structure applies local quality control by creating distinct blocked and exposed areas within the liquid inlet. The blocked area (2/3 to 3/4 of total area) reduces flow rate and pressure to prevent leakage, while the exposed area maintains sufficient liquid supply for atomization. This local differentiation allows the system to handle larger liquid quantities without increasing leakage risk.
