Atomizer Tube Inversion for Liquid Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol generating devices experience leakage due to excess aerosolizable matrix being absorbed by the liquid-conducting member, which can penetrate into the air inlet passage, affecting normal operation.
Innovation Solution
The atomizer design includes liquid inlet holes on the side wall of the atomizer tube, a liquid reservoir on the outer side, and a liquid-conducting member fitted to the inner side wall, with the atomizing assembly positioned higher than the liquid inlet holes, utilizing capillary action to manage aerosolizable matrix transfer and prevent excess absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid inlet holes are disposed on the middle region of the cotton-coated component, then the aerosolizable matrix can be transferred to the heating element through gravity and liquid-conducting characteristics, but a large amount of aerosolizable matrix is absorbed by the liquid-conducting member due to gravity, resulting in excess matrix that penetrates into the air inlet passage and causes leakage
Solution Approach 1:
The atomizing assembly is inverted to be positioned higher than the liquid inlet holes in the axial direction, reversing the conventional arrangement. This inversion prevents gravity from causing excess matrix absorption by the liquid-conducting member, as the atomizing assembly is now above the liquid inlet rather than below it, eliminating the leakage problem while maintaining proper matrix transfer
2Reliability
If the atomizing assembly is positioned higher than the liquid inlet holes, then excess aerosolizable matrix absorption is prevented and leakage is avoided, but the conventional gravity-driven transfer mechanism must be replaced with capillary action
Solution Approach 1:
The gravity-driven liquid transfer mechanism is replaced with capillary action. The liquid-conducting member utilizes capillary forces to draw the aerosolizable matrix from the liquid inlet holes to the atomizing assembly, eliminating the need for gravity to drive the transfer process and enabling the inverted configuration without compromising matrix supply
