Meshed Heating Disc for Electronic Cigarette Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomization modules in electronic cigarettes suffer from uneven heating due to a small contact area between the heating coil or disc and e-liquid conducting cotton, leading to poor atomization efficiency and stability issues.
Innovation Solution
The use of linen cotton in a circular shape as e-liquid conducting material with a uniformly disposed meshed heating disc, made of iron-chromium metal with eight concentric circles, increases the contact area and ensures even heating, while a seal ring enhances sealing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a heating coil or planar heating disc is used, then the structure is simple, but the contact area with e-liquid conducting cotton is small leading to uneven heating
Solution Approach 1:
The heating disc is designed with a meshed structure comprising concentric circles connected by radial lines, creating a three-dimensional mesh pattern on the disc surface. This curved and distributed mesh structure increases the effective contact area with the e-liquid conducting cotton compared to a planar surface, while maintaining manufacturing simplicity through standard metal forming processes.
Solution Approach 2:
The meshed heating disc creates a porous-like structure with numerous openings and channels formed by the intersecting concentric circles and radial lines. This mesh configuration allows e-liquid to penetrate and contact multiple heating points simultaneously, significantly increasing the effective heating contact area and improving heating uniformity across the e-liquid conducting cotton.
2Reliability
If common cotton is used as e-liquid conducting material, then the cost is low, but the high temperature resistance and stability are insufficient
Solution Approach 1:
The patent changes the material parameter of the e-liquid conducting cotton from common cotton to linen cotton. Linen cotton possesses superior high-temperature resistance and dimensional stability compared to common cotton, allowing it to maintain its structural integrity and e-liquid conduction properties under the thermal conditions of atomization, thereby extending the service life of the atomization module.
3Reliability
If a seal ring is added to the end cover, then the sealing property is improved, but the device complexity increases
Solution Approach 1:
A seal ring is added to the end cover to create an effective sealing interface. The seal ring, likely made of flexible or elastomeric material, forms a thin film barrier that prevents leakage between mating surfaces of the atomization module components. This simple additive approach provides reliable sealing without significantly increasing overall device complexity.
