Atomizer Vent Tube Design for Bubble Jamming Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic atomization devices, the vent opening in the liquid storage room often leads to bubble jamming due to bubbles adhering to the wall surface, hindering ventilation and causing insufficient liquid supply and dry heating during the atomization process.
Innovation Solution
The implementation of at least one vent channel with a vent tube on the inner wall surface of the liquid storage room, where the vent opening is positioned away from the inner wall surface and/or the liquid absorbing surface, preventing bubble adherence and ensuring effective ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vent opening is provided in the bottom wall or surrounding wall of the liquid storage room, then the air pressure can be balanced by replenishing ambient air, but bubbles are prone to adhere to the wall surface around the vent opening causing bubble jamming and hindering ventilation
Solution Approach 1:
The vent opening is extended in the vertical dimension by providing a vent tube that protrudes from the inner wall surface into the liquid storage room. This dimensional extension positions the vent opening away from the wall surface where bubbles tend to adhere, allowing air to be replenished without contact with bubble-prone wall areas, thus preventing bubble jamming while maintaining ventilation effectiveness
Solution Approach 2:
The vent tube acts as an intermediary structure between the vent opening and the liquid storage room interior. It provides a dedicated pathway for air replenishment that is spatially separated from the wall surface, preventing direct interaction between bubbles and the ventilation path, thereby ensuring reliable ventilation without bubble interference

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration prevents bubble adherence, maintaining proper air pressure balance and ensuring consistent liquid supply, thereby preventing dry heating and enhancing the atomization process efficiency.
Implementation Method 1
Driven by the pressure difference, the ambient air replenishes air to the liquid storage room through the vent structure to balance the air pressure
Implementation Method 2
an atomization assembly (13), the atomization assembly (13) including a liquid absorbing surface (133)
