Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing cores are prone to splashing and blockage due to easy accumulation and leakage of atomized liquid, leading to reduced atomizing efficiency and a smell of burning, with columnar cores experiencing deformation and planar cores having high manufacturing costs and condensate accumulation.
Innovation Solution
An atomizing core with a base having a passage with varying cross-sectional shapes, including a square upstream and circular or elliptical downstream sections, and a heating member covering over half the passage, preventing splashing and blockage by forming a step-like surface and ensuring uniform heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a columnar atomizing core with uniform inner diameter is used, then the structure is simple, but the heating wire is prone to coiling and deformation, causing unstable atomizing performance
Solution Approach 1:
The atomizing passage is divided into multiple sections with different cross-sectional shapes along the axial direction. The first atomizing passage has a first cross-sectional shape and the second atomizing passage has a second cross-sectional shape different from the first. This segmentation prevents heating wire coiling and deformation by providing distinct structural zones that stabilize the heating wire position while maintaining manufacturing simplicity.
2Ease of manufacture
If a planar ceramic atomizing core is used, then the manufacturing cost is reduced, but condensate accumulates and blocks the air channel
Solution Approach 1:
The atomizing passage incorporates curved or non-linear geometric transitions between different cross-sectional shapes. This curvature design prevents condensate accumulation by eliminating dead zones where liquid could pool, while still using planar ceramic materials that are cost-effective to manufacture. The curved passage geometry promotes continuous liquid flow without blockage.
3Device complexity
If the atomizing passage has a uniform cross-section, then the structure is simple, but atomized liquid accumulates and leaks, causing blockage
Solution Approach 1:
Different sections of the atomizing passage have different cross-sectional shapes optimized for their specific functions. The first section has one shape suitable for liquid introduction and the second section has another shape suitable for atomization. This local differentiation prevents liquid accumulation and leakage by creating favorable flow conditions in each zone, while the overall structure remains relatively simple.
4Volume of moving object
If the heating wire diameter is small, then the atomizing core is compact, but the heating wire deforms easily during production
Solution Approach 1:
The segmented atomizing passage structure with different cross-sectional shapes provides structural support and positioning features that stabilize the compact heating wire during production. The geometric transitions between sections create natural anchoring points that prevent wire deformation while maintaining the compact overall dimensions of the atomizing core.
