Flat Heating Body Structure to Prevent Atomizer Burnt Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of burnt cores in electronic atomizers arises due to the deformation of thin heating wires caused by the compression of the oil-guiding member, leading to poor fit and inefficient atomization.
Innovation Solution
A heat-generating body with fixing sections on both sides of the heating section provides sufficient support, ensuring the heating section remains flat and attached to the oil-guiding body, with conductive sections designed to minimize heat conduction and maintain uniform temperature distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the oil guiding member is made of compressible material (oil-guiding cotton), then it can be compressed to fit the assembly structure, but it squeezes and deforms the thin heating wire, causing burnt cores phenomenon
Solution Approach 1:
The heating wire is segmented into multiple sections with different functions: heating sections for atomization and fixing sections for structural support. The fixing sections have larger cross-sectional area to resist compression from the oil guiding member, while the heating sections maintain thin profile for efficient heating. This segmentation allows the heating wire to both adapt to the compressed assembly structure and maintain integrity during operation.
Solution Approach 2:
Different sections of the heating wire have different cross-sectional areas tailored to their specific functions. The fixing sections have larger cross-sectional area to provide mechanical support and resist compression, while the heating sections have smaller cross-sectional area for efficient heat generation. This local differentiation of properties resolves the contradiction between adaptability and reliability.
2Use of energy by moving object
If the heating wire is made very thin, then heating efficiency is improved, but it is easily deformed by compression from the oil guiding member, leading to poor fit and burnt cores
Solution Approach 1:
The heating wire is divided into heating sections with thin profile for efficient heating and fixing sections with thicker profile for mechanical strength. This segmentation allows the wire to achieve both high heating efficiency and sufficient compression resistance in different locations.
Solution Approach 2:
The cross-sectional area of the heating wire is locally optimized: thin in heating sections for energy efficiency, and thick in fixing sections for mechanical strength. This local quality differentiation resolves the contradiction between heating efficiency and compression resistance.
3Device complexity
If the heating section is not supported sufficiently, then the assembly structure is simpler, but the heating wire deforms and separates from the oil-guiding body, causing burnt cores
Solution Approach 1:
The fixing sections serve dual functions: they provide structural support for the heating wire and simultaneously act as attachment points to the oil-guiding body. This merging of support and attachment functions into a single integrated structure resolves the contradiction between simplicity and reliability.
Solution Approach 2:
The fixing sections are designed to perform multiple functions: mechanical support for the heating wire, attachment to the oil-guiding body, and maintenance of proper spacing. This multi-functionality eliminates the need for separate support structures, achieving both simplicity and reliability.

AI summary
The present application relates to a heat-generating body (100), the heat-generating body (100) is a flat sheet shaped structure, and includes a heating section (10) and conductive sections (20) extending from both lateral ends of the heating section (10) respectively, one or more fixing sections (13) are connected to the heating section (10) on each side of the heating section (10) in a longitudinal direction, and a cross-sectional area of each fixing section (13) is at least 10% larger than a cross-sectional area of a heating segment in the heating section (10). According to heat-generating body (100) in the present application, through setting the fixing sections (13) on both sides of the heating section (10) in the longitudinal direction, when the heat-generating body (100) is assembled into an atomization assembly of an atomizer, it is able to provide sufficient support strength to the heating section (10) through the fixing sections (13), thereby preventing the heating section (10) from deforming and ensuring that the heating section (10) is entirely attached to the oil-guiding body. Hence, it is able to keep the heating section (10) flat, so as to ensure that the heating section (10) is not separated from the oil-guiding body.
