Atomizing Unit Cap Break Mechanism Prevents Aerosol Reinjection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-burning type flavor inhalers face issues with aerosol reinjection into the reservoir, leading to inefficient use and potential leakage, which affects atomization efficiency and user experience.
Innovation Solution
The atomizing unit design includes a reservoir, an atomizing portion, and a cap that covers the supply port, where the atomizing portion and power supply member are broken when the cap is separated from the reservoir, preventing aerosol reinjection and ensuring proper atomization without leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cap is made removable to allow refilling, then ease of operation is improved, but aerosol reinjection into the reservoir occurs causing inefficiency and potential leakage
Solution Approach 1:
The cap is designed to break upon separation from the reservoir, which is a preliminary destructive action that prevents the cap from being removed and reattached. This preliminary breaking action ensures that refilling is impossible after initial use, thereby preventing aerosol reinjection and maintaining atomization efficiency throughout the product lifecycle.
Solution Approach 2:
The cap is designed as a disposable component that breaks after single use. This short-living design ensures that once the cap is separated from the reservoir, it cannot be reused, thereby preventing any subsequent opening of the reservoir and eliminating the risk of aerosol reinjection and leakage.
2Reliability
If the atomizing portion is made fragile to prevent reuse, then reliability is improved by preventing reinjection, but ease of repair deteriorates
Solution Approach 1:
The system is segmented into distinct functional components: the reservoir, the cap, and the atomizing portion. The cap and atomizing portion are designed to break upon separation, creating a clear segmentation that prevents reuse. This segmentation allows the main reservoir to remain intact and potentially reusable while the critical sealing components (cap and atomizing portion) are sacrificed to ensure reliability.
3Reliability
If the power supply member is positioned to break upon cap separation, then reliability is improved by ensuring complete disconnection, but device complexity increases
Solution Approach 1:
The power supply member is merged with the cap structure, creating an integrated assembly where the power supply, cap, and atomizing portion function as a unified component. When the cap breaks upon separation from the reservoir, the power supply member is automatically disconnected along with the cap and atomizing portion. This merging eliminates the need for separate disconnection mechanisms for electrical and mechanical components, actually reducing overall device complexity while ensuring reliable electrical disconnection.

AI summary
This atomization unit (111) is provided with a reservoir (11) that holds an aerosol source, an atomization part (13) that atomizes the aerosol source, and a cap body (16) that blocks a supply port for supplying the aerosol source to the reservoir, wherein movement of the cap body away from the reservoir causes the atomization part and/or a power supply member, which electrically connects a power source and the atomization part, to break.
