Ventilation Channel Tapering for Aerosol Substrate Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerosol generating apparatuses face issues with leakage of aerosol generating substrate into the ventilation channel, leading to reduced ventilation efficiency and potential damage to the apparatus.
Innovation Solution
A ventilation structure with a gradually increasing diameter from the installation groove to the liquid storage tank, featuring a first channel and two second channels, is designed to rapidly guide leaked aerosol generating substrate into an installation groove for storage, preventing accumulation in the ventilation channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a labyrinth structure or Tesla valve is used for the ventilation channel, then aerosol generating substrate leakage is prevented, but aerosol generating substrate accumulates in the ventilation channel reducing ventilation efficiency
Solution Approach 1:
The ventilation channel is divided into multiple sections with different cross-sectional areas. The channel includes a first ventilation channel section with a smaller cross-sectional area and a second ventilation channel section with a larger cross-sectional area, creating segmented zones that control substrate flow while maintaining ventilation efficiency
Solution Approach 2:
Different sections of the ventilation channel have different geometric properties tailored to specific functions. The first section has smaller dimensions for substrate containment, while the second section has larger dimensions for efficient air flow, creating local quality variations that resolve the contradiction

AI summary
A ventilation structure and an aerosol generating apparatus are provided. The ventilation structure includes a liquid storage tank, an atomization chamber located on one side of the liquid storage tank, and a supporting frame fixedly connected to the liquid storage tank. The supporting frame includes a ventilation channel in communication with the liquid storage tank, the installation groove and the atomization chamber, and an installation groove. The ventilation channel is gradually increased in diameter from an end in communication with the installation groove toward the liquid storage tank. The ventilation channel is of a structure with a bigger top and a smaller bottom, so that the aerosol generating substrate leaking into the ventilation channel can be rapidly guided into the installation groove and stored in the installation groove.
