Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices suffer from excessive flow of aerosol generating substrate into the atomizer, leading to immersion of the atomization core and a deviation from preset concentration requirements, negatively impacting user experience.
Innovation Solution
The device incorporates an atomizer with an isolated air outlet channel and a first liquid storage component, along with an additional e-liquid tank featuring a fluid channel and a second liquid storage component, utilizing capillary attraction to control the flow of aerosol generating substrate and minimize immersion of the atomization core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the additional e-liquid tank is in fluid communication with the atomizer, then the service life of the aerosol generating device is extended, but an excessive amount of aerosol generating substrate flows into the atomizer causing the atomization core to be directly immersed
Solution Approach 1:
The patent introduces a porous plate between the additional e-liquid tank and the atomizer. The porous structure allows controlled passage of aerosol generating substrate through capillary action while limiting excessive flow. This resolves the contradiction by enabling extended service life through supplementation while preventing over-flow that would cause direct immersion of the atomization core.
Solution Approach 2:
The porous plate acts as an intermediary component between the additional e-liquid tank and the atomizer. It mediates the flow of aerosol generating substrate, allowing necessary supplementation to extend service life while restricting excessive flow to prevent direct immersion. The intermediary structure balances both requirements.
2Quantity of substance
If an excessive amount of aerosol generating substrate flows into the atomizer, then the atomization core is directly immersed, but this causes deviation from preset concentration requirements and negative impact on user experience
Solution Approach 1:
The porous plate provides controlled substrate flow through its porous structure, regulating the amount of aerosol generating substrate that reaches the atomizer. This maintains preset concentration requirements by preventing excessive flow while ensuring adequate substrate availability for continuous operation.
3Manufacturing precision
If the air outlet channel is isolated from the main storage cavity, then aerosol concentration can be maintained, but the structure becomes more complex
Solution Approach 1:
The atomizer structure is segmented into distinct functional zones: the air outlet channel is isolated from the main storage cavity, creating separate pathways for aerosol generation and liquid storage. This segmentation maintains aerosol concentration by preventing direct mixing while organizing complexity into manageable functional modules.

The atomizer (10) includes an atomization component (11) and a first liquid storage component (12), where the atomization component (11) includes an air outlet channel (10b) and a main storage cavity (10a), the air outlet channel (10b) is isolated from the main storage cavity (10a), the air outlet channel (10b) extends in a first direction, an outlet of the air outlet channel (10b) is connected to the outside of the aerosol generating device, and the first liquid storage component (12) is at least partially located in the main storage cavity (10). The additional e-liquid tank (20) is provided with an additional storage cavity (20a) and a fluid channel (20b), where the fluid channel (20b) is configured to connect the additional storage cavity (20a) to the main storage cavity (10a), and the fluid channel (20b) is located on a side of the additional storage cavity (20a) close to the outlet of the air outlet channel (10b) in the first direction. According to the aerosol generating device in the embodiments of this application, during inhalation by users, it is difficult for the aerosol generating substrate in the additional storage cavity (20a) to enter the fluid channel (20b) and then enter the main storage cavity (10a), thereby helping control the aerosol generating speed of the atomization component.
