Air Inlet Liquid Blocking Structure for Aerosol Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-forming substrates and condensate in aerosol generating devices tend to leak through the air inlet, affecting the service life and safety performance of the power supply device over time.
Innovation Solution
An air inlet and liquid blocking structure featuring liquid blocking rib assemblies and drip channels is integrated into the aerosol generating device, which directs aerosol-forming substrates and condensate into the outer sleeve for absorption, preventing leakage through the air guiding hole and air inlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air inlet structure is used for air intake, then air can be supplied to the atomizing chamber, but aerosol-forming substrate and condensate can leak through the air inlet to the power supply device
Solution Approach 1:
The air inlet structure is segmented into multiple functional zones: air guiding holes for air intake, liquid blocking ribs for liquid prevention, and drip channels for controlled liquid drainage. This segmentation allows the single structure to simultaneously perform air intake and liquid blocking functions without interfering with each other.
Solution Approach 2:
Different regions of the air inlet structure have different properties: the air guiding hole region allows gas passage, the liquid blocking rib region creates liquid barriers, and the drip channel region provides controlled liquid flow paths. This local differentiation enables the structure to handle both air and liquid with appropriate characteristics in each zone.
2Reliability
If liquid blocking rib assemblies are added to prevent liquid leakage, then liquid leakage is reduced, but the structure becomes more complex
Solution Approach 1:
The liquid blocking rib assemblies are merged with the air inlet structure, forming an integrated component that combines air guiding and liquid blocking functions. The drip channels are also integrated into the same structure, creating a multi-functional air inlet assembly that reduces the need for separate liquid blocking components.
Solution Approach 2:
The air inlet structure is designed as a universal component that performs multiple functions: air intake through air guiding holes, liquid blocking through liquid blocking ribs, and controlled liquid drainage through drip channels. This multi-functionality eliminates the need for separate air inlet and liquid blocking components.

AI summary
An aerosol generating device has an air inlet and liquid blocking structure, and an atomizer. The air inlet and liquid blocking member includes an air intake pipe and at least two groups of liquid blocking rib assemblies. The air intake pipe includes an opening end, a closed end, and an outer peripheral wall, the opening end is provided with an air inlet, the outer peripheral wall defines an air guiding hole. The liquid blocking rib assemblies are arranged at intervals along the axial direction of the intake pipe. Each group of liquid blocking rib assemblies includes at least one liquid blocking section protruding radially along the intake pipe and arranged along a circumferential direction. One or more dripping port O are defined between the liquid blocking sections located on the same circumference.
