Solution Overview

Problem

Conventional atomizers suffer from excessive heat loss and inefficient atomization due to direct contact between the heating element and the liquid-guiding surface, leading to poor atomization effects and insufficient smoke volume.

Innovation Solution

The atomizing structure features an atomizing core assembly with a heating element partially embedded in the atomizing portion, where the first atomizing surface and liquid-absorbing surface are physically isolated, allowing for indirect contact with the atomizing medium, creating a long distance for heat transfer and ensuring efficient liquid supply through a guiding portion with a large liquid-guiding area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the heating element is directly fixed to the liquid-guiding surface, then the heating element can be easily mounted, but the heat loss increases and atomization efficiency decreases

Engineering Contradiction:
Improveheating element mountingVSAvoidheat loss
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent introduces a liquid-guiding element as an intermediary component between the heating element and the atomizing medium. The heating element is mounted on the liquid-guiding element, which then guides the liquid to the heating surface. This intermediary structure prevents direct contact between the heating element and bulk liquid, reducing heat loss to the liquid reservoir while maintaining effective heating at the atomization surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the heating element is in direct contact with the liquid-guiding surface, then the structure is simple, but the atomization effect is poor and smoke volume is insufficient

Engineering Contradiction:
Improvestructure complexityVSAvoidatomization efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent segments the atomizer into distinct functional components: a heating element, a liquid-guiding element, and an atomizing medium reservoir. The liquid-guiding element is further divided into a liquid-guiding surface that contacts the heating element and a liquid storage region. This segmentation allows each component to perform its specific function optimally, improving atomization efficiency while maintaining reasonable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by creating a specific liquid-guiding surface with controlled thermal and fluid properties. This surface is designed to have selective contact: it allows liquid to reach the heating element efficiently while preventing excessive heat transfer to the bulk liquid. The localized optimization of this surface improves atomization performance without requiring complete redesign of the entire structure.

Inventive Principle:
Principle #3Local quality

3Power

If the heating element directly heats the atomizing medium at the bottom position, then heating is efficient, but the atomizing medium deteriorates due to high temperature

Engineering Contradiction:
Improveheating efficiencyVSAvoidmedium deterioration
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The liquid-guiding element serves as a thermal intermediary that controls heat transfer from the heating element to the atomizing medium. It allows sufficient heat to reach the atomization surface for efficient vaporization while limiting excessive heat transfer to the bulk liquid reservoir, thereby preventing thermal degradation of the atomizing medium in the storage region.

Inventive Principle:
Principle #24Intermediary (Mediator)
