Atomizer Air Passage Design for Liquid Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers for electronic cigarettes suffer from tobacco liquid leakage through air inlets during use or transportation, compromising user experience.
Innovation Solution
An atomizer design featuring a liquid supply with air inlets and outlets, an atomizing device with a heating element and liquid conducting element, and an air pipe forming an annular air passage, which prevents liquid leakage through interference fit and air passage configuration, ensuring aerosol delivery without external liquid loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air inlets are provided at the end of liquid supply adjacent to mouthpiece, then aerosol generation is enabled, but tobacco liquid leaks from air inlets during use or transportation
Solution Approach 1:
The air passage is divided into two separate sections: an internal air passage within the liquid supply and an external air passage outside the liquid supply. These two passages are connected at the atomizing device, creating distinct fluid pathways that prevent liquid from mixing with air and leaking through air inlets while still enabling proper aerosol generation through the atomizing device
Solution Approach 2:
The atomizing device serves as an intermediary component that connects the internal and external air passages. It receives air from both passages and combines them at the atomizing chamber, where liquid is properly atomized before being delivered to the mouthpiece, preventing direct liquid leakage through air inlets
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents tobacco liquid leakage, enhancing user experience by ensuring consistent aerosol delivery and maintaining the atomizer's internal environment.
Implementation Method 1
a heating element in contact with the liquid conducting element and configured for heating the liquid conducting element
Implementation Method 2
a liquid conducting element in the atomizing chamber and in communication with the liquid inlets, the liquid conducting element being configured for conducting the liquid from the liquid inlets to the heating element
