Atomizing Core Sealing Structure for Condensate Backflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensate backflow in atomizing devices can cause failure of electrical components due to liquid erosion.
Innovation Solution
The atomizing core features limiting members at both ends to secure oil-conducting cotton, forming enlarged ends for condensate absorption, and a sealing member with protrusions to form condensate adsorption gaps, while an independent atomizing and control airway with a condensate recovery space prevents condensate from reaching sensitive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizing core heats the substrate to generate aerosol, then the aerosol can be delivered to the user, but the temperature decrease during aerosol flow causes partial condensate formation that may backflow and damage electrical components
Solution Approach 1:
The patent introduces oil-conducting cotton as an intermediary substance between the porous body and the air passageway. This cotton material serves as a mediator that selectively absorbs condensate while allowing aerosol to pass through, preventing condensate from reaching electrical components. The cotton acts as a buffer zone that intercepts harmful condensate backflow without interfering with the useful aerosol delivery function.
Solution Approach 2:
The patent extracts the harmful condensate from the aerosol stream by using oil-conducting cotton to separate and remove condensate droplets. The cotton selectively takes out the condensed liquid phase from the aerosol mixture, allowing the remaining aerosol to continue flowing to the mouthpiece while the extracted condensate is retained in the cotton or directed to a collection area.
2Reliability
If limiting members are added to the porous body to secure oil-conducting cotton, then condensate absorption capacity is improved, but the device structure becomes more complex
Solution Approach 1:
The limiting members serve multiple functions simultaneously: they provide structural support to the porous body, define the installation position for oil-conducting cotton, and create enlarged diameter ends that enhance condensate absorption capacity. By making these components multi-functional, the patent reduces the need for additional separate structures, thereby managing complexity while improving condensate management.
Solution Approach 2:
The patent merges the functions of structural support, condensate absorption, and component positioning into integrated features. The limiting members combine support and positioning functions, while the enlarged diameter ends created by these limiting members simultaneously provide structural reinforcement and increase the volume available for condensate absorption, merging multiple benefits into a single structural feature.
3Reliability
If a sealing member with protrusions is added to form condensate adsorption gaps, then condensate backflow is prevented, but the manufacturing complexity increases
Solution Approach 1:
The sealing member is segmented with multiple protrusions that create discrete condensate adsorption gaps. This segmentation allows the sealing member to perform both sealing and condensate management functions while maintaining a relatively simple overall structure. The protrusions can be manufactured as standard features using common molding or machining techniques, avoiding complex manufacturing processes.
