Solution Overview

Problem

Current e-cigarette atomizing cores face issues with poor heating efficiency, local overheating, and inadequate liquid supply due to the limitations of traditional liquid conducting cotton and heating wire designs, leading to compromised taste and reduced user satisfaction.

Innovation Solution

A 3D heating component with a convex-concave pattern and guide channels is introduced, which replaces the traditional liquid conducting cotton and heating wire, providing uniform heating, preventing dry burning, and ensuring stable liquid supply through the use of a grid-like heating sheet and porous ceramic liquid conducting components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the liquid conducting cotton is made tight to prevent leakage, then liquid leakage is prevented, but liquid supply becomes insufficient causing local dry burning

Engineering Contradiction:
Improveliquid leakage preventionVSAvoidliquid supply
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The liquid conducting cotton is segmented into multiple layers with different densities. The first liquid conducting cotton layer has a first density and the second liquid conducting cotton layer has a second density different from the first. This segmentation allows different regions to perform different functions: one layer prevents leakage while the other ensures sufficient liquid supply to the heating wire.

Inventive Principle:
Principle #1Segmentation

2Power

If the heating wire power is increased to improve atomization, then atomization efficiency is improved, but the liquid conducting cotton burns out faster

Engineering Contradiction:
Improveatomization powerVSAvoidservice life
Core Design Contradiction:
PowerVSDuration of action of moving object

Solution Approach 1:

Different regions of the liquid conducting cotton have different densities optimized for their specific functions. The region closer to the heating wire has density optimized for liquid supply, while the outer region has density optimized for leakage prevention. This local quality differentiation ensures adequate liquid supply even at high power levels, preventing burnout and extending service life.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the liquid conducting cotton is made loose to improve liquid supply, then liquid supply is improved, but liquid leakage occurs

Engineering Contradiction:
Improveliquid supplyVSAvoidliquid leakage prevention
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The liquid conducting cotton is divided into two layers with different densities. The looser layer provides adequate liquid supply to the heating wire, while the denser layer prevents liquid leakage. This segmentation resolves the contradiction by assigning different density characteristics to different functional regions.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If traditional single-layer liquid conducting cotton is used to simplify structure, then device complexity is reduced, but heating uniformity deteriorates

Engineering Contradiction:
Improveliquid conducting cotton structureVSAvoidheating uniformity
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The liquid conducting cotton is segmented into two layers with different densities, where the first layer has a first density and the second layer has a second density. This segmentation improves heating uniformity by ensuring consistent liquid supply to the heating wire, preventing local dry burning and overheating, while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention provides a 3D atomizing heating component which comprises a plate body having upper and lower surfaces and the plate body providing with a plurality of 3D heating units for guiding, heating and atomizing the e-liquid. Each of the 3D heating units has a through hole disposed in the plate body and guide channels distributed regularly at the periphery of the through hole, the through hole runs through the upper and lower surfaces of the plate body, and the guide channels are recessed from the surface of the plate body and communicate with the through hole. The guide channels of the adjacent 3D heating units are connected with each other on the surface of the plate body, and the said plurality of 3D heating units form a regular convex-concave pattern on the surface of the plate body. Due to the structure, atomized cigarette liquid is smooth and good in taste. The plate body can be continuously heated to atomize the e-liquid, and the atomized e-liquid is carried away by the outside air through the through holes, thereby realizing large heating area as well as the demand of large amount of smoke, preventing dry burning, effectively improving the problem of liquid supply, and realizing integration of liquid supply and atomization. The present invention also provides a 3D liquid conducting component with a plurality of 3D liquid conducting units. The liquid conducting member may be made of the same material as the conventional liquid conducting cotton but has the characteristics of smooth and uniform liquid supply, anti-dry burning and liquid leakage prevention as compared with the liquid conducting component made by the conventional method. A 3D heating component and 3D liquid conducting component provided by the invention effectively improve the taste and user experience. The manufacture thereof is easy.
