Atomizer Dual-Tank Venting for Temperature-Driven Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers fail to reliably prevent liquid leakage during temperature fluctuations or in the late stages of inhalation, leading to waste of high-viscosity atomization medium and blocked inhalation channels.
Innovation Solution
Incorporating a second liquid storage tank with a sacrificial medium of lower viscosity than the atomization medium, which leaks into a collecting tank to prevent atomization medium leakage, and using a separator to equalize air pressures, ensuring reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If negative pressure is used to lock the atomization medium, then liquid leakage is prevented under normal conditions, but liquid leakage cannot be reliably prevented during temperature fluctuations or in the late stage of inhalation
Solution Approach 1:
The liquid storage system is segmented into two separate tanks: a first liquid storage tank for the atomization medium and a second liquid storage tank for the sacrificial medium. This segmentation allows each tank to serve its specific function - the first tank maintains reliable liquid leakage prevention while the second tank adapts to temperature changes and inhalation stages by providing pressure equalization.
Solution Approach 2:
The sacrificial medium in the second liquid storage tank acts as an intermediary that absorbs pressure changes during temperature fluctuations and inhalation stages. It mediates between the external environment and the atomization medium, preventing direct pressure impacts that would cause leakage while allowing the atomization medium to remain stable.
2Reliability
If a separator is added to prevent atomization medium and sacrificial medium from mixing, then medium separation is achieved, but device complexity increases
Solution Approach 1:
A porous separator is used between the first and second liquid storage tanks to prevent the atomization medium and sacrificial medium from mixing while allowing pressure equalization. The porous structure provides effective separation without requiring complex mechanical components, thus achieving reliable medium separation with minimal increase in device complexity.
