Electronic Cigarette Atomizer with Memory Foam and U-Shaped Air Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes lack a mechanism to prevent e-liquid condensate from depositing and leaking out of the atomizer, as they do not incorporate memory foam around the heating wire, leading to inefficiencies and potential e-liquid loss.
Innovation Solution
The electronic cigarette design includes an atomization assembly with a memory foam wrapped around the heating wire, a U-shaped air passage to prevent e-liquid leakage, and a pneumatic switch driven by airflow, which absorbs and reuses condensate e-liquid, and integrates a gasket seal to secure the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If memory foam is added around the heating wire, then e-liquid leakage is prevented and condensate is absorbed, but device complexity increases
Solution Approach 1:
Memory foam is introduced as an intermediary material between the heating wire and the atomizer housing. It serves multiple functions: absorbing excess e-liquid, preventing leakage, and maintaining structural integrity, thereby resolving the contradiction between reliability improvement and complexity increase
Solution Approach 2:
The memory foam utilizes its porous structure to absorb and retain condensate e-liquid through capillary action, preventing it from leaking out of the atomizer while maintaining a compact design
2Reliability
If a U-shaped air passage is implemented, then e-liquid leakage is prevented, but manufacturing complexity increases
Solution Approach 1:
The air passage is segmented into distinct sections (vertical air passage, bottom air passage, curve air passage) that can be manufactured separately and then assembled, reducing the difficulty of creating the complete U-shaped structure in a single manufacturing process
Solution Approach 2:
The air passages are nested within the existing structural components of the atomizer, utilizing available space and integrating the airflow channels into the overall device architecture rather than adding separate external structures
3Loss of substance
If memory foam is used to absorb condensate, then e-liquid loss is reduced, but device weight increases
Solution Approach 1:
The memory foam's porous structure provides high absorption capacity relative to its volume and weight, allowing it to capture and retain condensate e-liquid effectively while minimizing the added mass to the device
Solution Approach 2:
The memory foam recovers condensate e-liquid that would otherwise be lost, capturing it in its porous structure and making it available for reuse in the atomization process, thereby reducing e-liquid loss
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
The solution effectively prevents e-liquid leakage, reuses absorbed condensate for the heating wire, and ensures efficient airflow operation, enhancing the performance and reliability of the electronic cigarette by utilizing the memory foam and U-shaped air passage.
Implementation Method 1
The memory foam is wrapped around the heating wire and disposed in the fixed seat... The memory foam of the atomization assembly can absorb the condensate at the upper end and the e-liquid deposited on the lower end of the atomization assembly
Implementation Method 2
The heating wire is horizontally disposed in the memory foam... Electronic cigarettes atomize nicotine-containing e-liquid
Implementation Method 3
the silicone pad comprises a curve air passage connected to the pneumatic switch; when in use, the air flows through the curve air passage to drive the pneumatic switch to work

AI summary
An electronic cigarette including an atomization assembly and a battery assembly. The atomization assembly includes an e-liquid storage tank and a limit cover disposed in the e-liquid storage tank, and the limit cover includes an air intake and an air passage. The e-liquid storage tank includes a side wall, a vertical air passage disposed along the side wall, and a bottom air passage communicating with the vertical air passage and the air intake of the limit cover. The side wall includes an air inlet communicating with the vertical air passage. When in use, air enters the atomization assembly via the air inlet, sinks along the vertical air passage and enters the bottom air passage of the atomization assembly, passes through the air intake of the limit cover, flows upwards in the air passage of the limit cover, and discharges from the top part of the atomization assembly.
