Atomizer Air-Path Structure for Stable Aerosol Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices suffer from insufficient aerosol concentration and concentration attenuation due to pressure differences in the liquid storage cavity, leading to inadequate liquid flow and inefficient aerosol generation.
Innovation Solution
The atomizer design includes an air path communication between the liquid storage cavity and the outside, forming first and second air channels to balance pressure and maintain the atomization assembly in an adequate state for absorbing aerosol-generating material, ensuring consistent aerosol concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid storage cavity is sealed to maintain pressure, then liquid flow is improved, but aerosol concentration becomes insufficient and attenuates during continuous generation
Solution Approach 1:
The air path is divided into multiple channels (first air channel and second air channel) with different functions: the first air channel provides ventilation to balance pressure, while the second air channel allows air to pass through the liquid storage member to the atomization assembly. This segmentation allows the system to maintain both pressure balance and adequate aerosol concentration simultaneously.
Solution Approach 2:
The liquid storage member acts as an intermediary component that allows air to pass through it via the second air channel while blocking liquid flow. This intermediary function enables the atomization assembly to receive both liquid and air, maintaining adequate concentration without requiring the liquid storage cavity to be completely sealed.
2Speed
If pressure is increased to improve liquid flow, then liquid flow rate is improved, but aerosol concentration attenuates during continuous use
Solution Approach 1:
The first air channel provides a feedback mechanism where air flows from the atomization assembly back to the liquid storage cavity, dynamically balancing the pressure inside the cavity with the outside pressure. This feedback loop ensures that pressure increases are compensated, maintaining both liquid flow rate and aerosol concentration during continuous operation.
Solution Approach 2:
The system uses pneumatic principles by introducing air channels that allow gas flow to balance pressure differences. The first air channel creates a pressure equalization path, while the second air channel allows controlled air passage through the liquid storage member, using pneumatic pressure management to maintain both liquid flow and aerosol concentration.
3Productivity
If the atomization assembly is sealed to prevent leakage, then aerosol generation is improved, but pressure balance is lost and concentration attenuates
Solution Approach 1:
The air path is segmented into two functional channels: the first air channel handles pressure balance by allowing air flow between the liquid storage cavity and outside, while the second air channel handles aerosol generation by allowing air to pass through the liquid storage member to the atomization assembly. This segmentation resolves the contradiction by assigning different functions to different air paths.
Solution Approach 2:
The liquid storage member serves as an intermediary that differentially allows air and liquid: it permits air to pass through via the second air channel for atomization while blocking liquid to prevent leakage. This intermediary function enables the atomization assembly to remain sealed for efficient aerosol generation while maintaining pressure balance through the first air channel.
