Atomizer Air Supplementary Inlet for E-Cigarette Pressure Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers face issues where negative pressure in e-liquid storage tubes can cause the heating element to burn out due to lack of air, and air inlets can lead to e-liquid leakage, resulting in short circuits.
Innovation Solution
The atomizer design includes an atomizing tube with both an e-liquid inlet and an air supplementary inlet, where the cylindrical ring adjacent to the air inlet creates an air passage that allows external air to balance pressure, ensuring e-liquid flow into the heating element without leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an air inlet is disposed under the e-liquid inlet to allow air to enter the e-liquid storage tube, then the heating element can be prevented from burning out due to negative pressure, but e-liquid may flow through the air inlet and cause short circuit
Solution Approach 1:
The air inlet is segmented into multiple small holes rather than a single large opening. This segmentation allows air to enter the e-liquid storage tube to balance pressure and prevent heating element burnout, while the small hole size prevents e-liquid from flowing through and causing short circuits.
Solution Approach 2:
The air inlet holes are specifically positioned at a location where they can effectively balance pressure without allowing e-liquid passage. The local geometry and positioning of these holes create a quality difference that permits gas flow while blocking liquid flow, resolving the contradiction between pressure balancing and leakage prevention.
2Object-affected harmful factors
If no air is supplemented to the e-liquid storage tube, then e-liquid can be prevented from leaking through the air inlet, but negative pressure causes the heating element to burn out
Solution Approach 1:
The air inlet is designed as multiple small holes that allow sufficient air flow to balance negative pressure and protect the heating element, while the segmented structure with small individual hole sizes prevents e-liquid from passing through and causing leakage.
3Reliability
If the air inlet is made larger to improve air flow and pressure balancing, then the heating element is better protected from burnout, but e-liquid can more easily flow through causing short circuit
Solution Approach 1:
Instead of using a single large air inlet opening, the design segments the air inlet into multiple small holes. This segmentation provides sufficient total air flow area for pressure balancing and heating element protection, while each small individual hole maintains a size that prevents e-liquid passage and short circuit risk.

Function Achieved in This Case
This design ensures smooth e-liquid flow into the heating element, preventing burnout and leakage, while maintaining balanced pressure for efficient atomization.
Implementation Method 1
external air flows through the air supplementary inlet and enters the e-liquid storage tube via the air passage to balance the pressure
Implementation Method 2
the heating element to atomize the e-liquid
Implementation Method 3
the e-liquid flows through the e-liquid inlet and bubbles may produce; the bubbles are suspended in the e-liquid and can be discharged from the air supplementary inlet
