Flexible Membrane Sealing for Electronic Cigarette Atomizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing devices in electronic cigarettes face issues with tobacco oil leakage due to the configuration of the porous body and liquid storage components, which are not effectively sealed, leading to inefficiencies in smoke generation and user experience.
Innovation Solution
The atomizing device incorporates an upper and lower oil obstructing ring with a tubular electrode and flexible membrane, where the flexible membrane, made of silicon dioxide, deforms to facilitate airflow and prevent oil leakage by forming a seal between the tubular electrode and screw sleeve, ensuring air passage while maintaining oil containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a porous body is used to absorb tobacco oil from the reserving space, then the atomization process can proceed, but tobacco oil may leak out of the atomizing device
Solution Approach 1:
The patent employs a flexible membrane made of elastomer material that can deform elastically. This membrane is configured to seal between the porous body and the housing, preventing tobacco oil leakage while allowing the atomization process to continue. The flexible nature of the membrane enables it to adapt to dimensional changes during atomization, maintaining the seal effectively.
Solution Approach 2:
The patent utilizes the dynamic deformation capability of the flexible membrane to maintain sealing under varying conditions. As the porous body absorbs tobacco oil and undergoes dimensional changes, the membrane dynamically adjusts its shape and position to maintain contact and sealing, ensuring continuous oil containment throughout the atomization process.
2Productivity
If the porous body extends into the tobacco oil reserving space to absorb oil, then atomization can occur, but the sealing mechanism becomes insufficient
Solution Approach 1:
The patent introduces a flexible membrane as a simple yet effective sealing component. This thin film structure seals the interface between the porous body and the housing without adding significant structural complexity. The membrane's flexibility allows it to conform to the existing geometry, providing effective sealing with minimal additional design complexity.
Solution Approach 2:
The flexible membrane acts as an intermediary sealing element between the porous body and the housing. Rather than redesigning the entire sealing mechanism, the membrane serves as a mediating component that fills the sealing gap and prevents oil leakage, simplifying the overall sealing structure while maintaining atomization functionality.
3Reliability
If a rigid sealing structure is used to prevent oil leakage, then sealing is improved, but airflow passage is restricted
Solution Approach 1:
The flexible membrane provides sealing while maintaining airflow passage because of its elastic properties. Unlike rigid sealing structures that would block air flow, the membrane can deform to allow air to pass through while still preventing tobacco oil leakage. This resolves the contradiction by providing both sealing and airflow functionality.
Solution Approach 2:
The patent changes the physical parameter of the sealing material from rigid to flexible. This parameter change allows the sealing structure to adapt its degree of openness based on operational conditions, maintaining oil containment while permitting necessary airflow for atomization to occur efficiently.
