Atomizer Bubble Guiding Element for E-Cigarette Liquid Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizers face issues with smooth e-liquid supply due to bubble accumulation near the e-liquid absorbing surface, which affects the absorption process.
Innovation Solution
The atomizer design incorporates a bubble guiding element with an obliquely arranged surface opposite to the e-liquid absorbing surface, directing bubbles away from the absorption area and maintaining a sufficient distance to ensure continuous e-liquid supply, along with a support structure that includes a sealing base and airflow channel for efficient e-liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a porous ceramic element with micropores is used for e-liquid absorption and air exchange, then the atomization function is improved, but bubbles accumulate at the e-liquid guiding channel affecting e-liquid absorption
Solution Approach 1:
The patent extracts the harmful bubbles from the e-liquid guiding channel area by introducing a separate air outlet channel that independently guides bubbles away from the e-liquid absorption path. This separates the bubble discharge function from the e-liquid guiding function, preventing bubble accumulation while maintaining effective e-liquid absorption and atomization.
2Productivity
If the porous element is installed inside an accommodation support with an e-liquid guiding channel, then the e-liquid transfer function is improved, but bubbles block the channel reducing absorption efficiency
Solution Approach 1:
The patent segments the fluid guidance system into separate channels: an e-liquid guiding channel for liquid transfer and an air outlet channel for bubble removal. This segmentation allows independent optimization of each function, ensuring continuous e-liquid supply while efficiently removing bubbles that would otherwise block the absorption process.
Solution Approach 2:
The air outlet channel acts as an intermediary pathway that mediates between the porous element interior and the exterior environment. It provides a dedicated route for bubbles to escape without interfering with the e-liquid guiding channel, thus maintaining absorption continuity while preserving transfer efficiency.
3Stress or pressure
If bubbles are allowed to emerge from the e-liquid absorbing surface to maintain air pressure, then the air pressure balance is improved, but bubble accumulation affects e-liquid absorption
Solution Approach 1:
The patent extracts bubbles from the problematic location (e-liquid guiding channel and absorption surface area) by providing a dedicated air outlet channel. This allows air pressure balance to be maintained through controlled bubble release while preventing bubble accumulation that would disrupt e-liquid absorption smoothness.

AI summary
An atomizer and an electronic cigarette are provided. The atomizer comprises an outer housing, and an e-liquid storage chamber and an atomization assembly are disposed in the outer housing. The atomization assembly comprises a porous element and a heating element. The porous element comprises an e-liquid absorbing surface. A bubble guiding element opposite to the e-liquid absorbing surface is further provided in the outer housing, and comprises a bubble guiding surface opposite to the e-liquid absorbing surface. At least a portion of the bubble guiding surface is obliquely configured in a direction facing away from the e-liquid absorbing surface, such that bubbles emerging from the e-liquid absorbing surface of the porous element are guided toward the direction facing away from the e-liquid absorbing surface.
