Ultrasonic E-Cigarette Atomizer Airflow Redesign
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizers have poorly designed air flow channels, leading to e-liquid particles being directly sprayed into the user's mouth, causing a poor smoking experience and potential scalding, and the e-liquid guide cotton is prone to rapid aging and leakage due to improper design and lack of a mechanism to cut off the e-liquid path.
Innovation Solution
The ultrasonic electronic cigarette atomizer features a re-designed air flow channel where the air inlet is opposite to the atomization region, with a two-layer e-liquid guide cotton structure and a mechanism to align/disalign e-liquid passing holes when not in use, ensuring efficient re-atomization and preventing e-liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air outlet channel is perpendicular to the ultrasonic atomization sheet, then the structure is simple, but smoke with large e-liquid particles is directly sprayed to the user's mouth causing poor mouthfeel and potential scalding
Solution Approach 1:
The air outlet channel is divided into multiple segments: a first air outlet channel perpendicular to the atomization sheet for direct smoke discharge, and a second air outlet channel parallel to the atomization sheet for cooled smoke discharge. This segmentation allows different smoke streams to be separated, with the second channel providing a pathway for cooler, finer particles away from the user's mouth.
Solution Approach 2:
A baffle plate is introduced as an intermediary component between the first and second air outlet channels. The baffle plate redirects the hot smoke from the first channel into the second channel, allowing thermal mixing and cooling before the smoke exits to the user's mouth, thereby reducing scalding risk while maintaining simple overall structure.
2Device complexity
If the air inlet is formed on the side wall of the housing, then the structure is simple, but the hand easily blocks the air inlet when holding the electronic cigarette
Solution Approach 1:
The air inlet is repositioned from the side wall (horizontal dimension) to the bottom surface (vertical dimension) of the housing. This dimensional change ensures that the air inlet is located below the user's hand when holding the device, eliminating blockage while maintaining structural simplicity.
3Device complexity
If a single-layer e-liquid guide cotton is used, then the structure is simple, but the cotton ages rapidly in the center of the ultrasonic atomization sheet and may break
Solution Approach 1:
The single-layer e-liquid guide cotton is segmented into two layers: a first e-liquid guide cotton layer and a second e-liquid guide cotton layer. This multi-layer structure distributes the mechanical stress and thermal aging effects across multiple layers, preventing rapid degradation and breakage while maintaining simple overall design.
4Device complexity
If the e-liquid path cannot be cut off, then the structure is simple, but e-liquid accumulation occurs on the ultrasonic atomization sheet surface causing leakage and immersion
Solution Approach 1:
The e-liquid guide cotton structure is made dynamic through a rotating component that can adjust the alignment of e-liquid passing holes. When rotated to a first position, the holes align for normal e-liquid flow; when rotated to a second position, the holes misalign to cut off the e-liquid path, preventing accumulation and leakage while maintaining simple overall structure.

Function Achieved in This Case
This design improves the mouthfeel of the smoke by reducing large e-liquid particles, prolongs the service life of the atomizer components, and prevents e-liquid leakage, resulting in a better user experience and faster atomization start-up.
