Atomizer Back-Suction Channel Structure for Condensate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power atomization cores generate a large amount of aerosols, leading to condensate formation in the airflow channel, which can leak out or be inhaled by the user due to insufficient back-suction, especially when the atomizer is inverted.
Innovation Solution
The atomizer design includes a housing with a liquid storage space and gas flow path, featuring a sealing member with back-suction channels that connect the liquid storage member to a liquid absorbing member, allowing condensates to be sucked back into the storage space, thereby preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-power atomization core is used to generate more aerosols, then the atomization performance is improved, but the condensate formation increases leading to leakage
Solution Approach 1:
A liquid absorbing member is introduced as an intermediary component between the airflow channel and the liquid storage cavity. This member absorbs excess condensates before they can leak out or be inhaled, serving as a mediator that resolves the contradiction between high aerosol generation and condensate control
Solution Approach 2:
The harmful condensates are extracted from the airflow channel through back-suction channels and directed into the liquid storage cavity where they are absorbed by the liquid absorbing member, removing the harmful factor from the main system
2Reliability
If back-suction channels are added to prevent condensate leakage, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The back-suction channels are integrated into the sealing member structure, merging the sealing function with the condensate recovery function. This consolidation reduces the number of separate components and simplifies the overall device structure while maintaining reliability
Solution Approach 2:
The sealing member is designed to perform multiple functions: sealing the liquid storage cavity, providing back-suction channels for condensate recovery, and facilitating fluid communication between different components. This multi-functionality reduces device complexity by eliminating the need for separate dedicated components

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 back-suction channels effectively prevent condensate leakage and inhalation by absorbing excess condensates, improving user experience and ensuring reliable operation of the atomizer.
