Atomizer Liquid-Absorbing Assembly for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-forming substrates in atomizers and aerosol generating devices are prone to leakage from the connection between the liquid storage assembly and atomizing assembly, or leak to the outside due to gravity, causing user inconvenience.
Innovation Solution
The atomizing assembly is designed with an air inlet passage communicating with the atomizing chamber, and a liquid absorbing member is placed between the liquid storage and atomizing chambers to prevent direct communication, with the air outlet end positioned closer to the smoke outlet, ensuring that unatomized aerosol-forming substrate and condensate do not leak externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid storage chamber and atomizing chamber are directly connected, then the aerosol-forming substrate can flow freely for atomization, but the substrate leaks from the connection and to the outside due to gravity
Solution Approach 1:
A liquid absorbing member is introduced as an intermediary component between the liquid storage chamber and atomizing chamber. This member absorbs and retains the aerosol-forming substrate, preventing direct gravitational flow while enabling controlled atomization when heated, thus resolving the contradiction between free flow for atomization and leakage prevention.
Solution Approach 2:
The state of the aerosol-forming substrate is changed from liquid (prone to leakage) to solidified form through cooling. The liquid absorbing member causes the substrate to solidify, which prevents gravitational leakage while still allowing vaporization and atomization when heated during use.
2Volume of stationary object
If the air outlet end is positioned far from the smoke outlet, then there is more space for unatomized substrate, but the unatomized substrate and condensate leak to the outside
Solution Approach 1:
The liquid absorbing member acts as an intermediary that contains and absorbs unatomized substrate and condensate. By positioning the air outlet end closer to the smoke outlet, the design relies on the liquid absorbing member's absorption capability rather than spatial distance to prevent leakage, thus resolving the contradiction between space availability and containment.
3Volume of stationary object
If the liquid absorbing member is positioned far from the smoke outlet, then there is more space, but the leaked substrate can escape to the outside
Solution Approach 1:
The liquid absorbing member serves as a protective intermediary that intercepts and absorbs any substrate that might otherwise leak to the outside. Its positioning and absorption properties ensure that even with reduced space, leaked substrate is contained and absorbed rather than escaping, resolving the contradiction between space and leakage prevention.
