Atomizer Air Outlet Design for Bubble Discharge

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing atomizers face issues with air bubbles occupying space and hindering the flow of e-liquid due to ineffective bubble removal mechanisms.

Innovation Solution

The atomizer design includes an air outlet and air inlet system that allows bubbles to be discharged, ensuring e-liquid can flow freely by incorporating a detachable threaded joint and a base with air holes for clear air passage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional atomizer design is used, then e-liquid injection is simple, but air bubbles occupy space and hinder e-liquid flow

Engineering Contradiction:

Improvee-liquid flow rateVSAvoidbubble obstruction

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the bubble removal function from the conventional atomizer design by adding a dedicated air outlet channel. This separate channel allows bubbles to be discharged from the atomizer cavity independently, preventing them from occupying space and blocking e-liquid flow paths.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The atomizer cavity is segmented into distinct functional zones with separate air inlet and air outlet channels. The air inlet channel introduces air for vaporization, while the air outlet channel specifically handles bubble discharge, creating functional segmentation that resolves the bubble obstruction problem.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If threaded joint is detachably embedded, then assembly is simplified, but sealing reliability may be compromised

Engineering Contradiction:

Improveassembly simplicityVSAvoidsealing performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent combines multiple functions into the threaded joint structure: mechanical connection, positioning, and sealing. The sealing ring is integrated into the threaded joint design, merging the sealing function with the assembly structure to maintain reliability while preserving ease of assembly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A sealing ring is introduced as an intermediary element between the threaded joint and the atomizer cavity. This sealing ring mediates the connection, ensuring reliable sealing while allowing the threaded joint to remain detachably embedded for easy assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)
