Solution Overview

Problem

Existing atomizers in electronic cigarettes with bottom air-inlet structures are prone to oil leakage, which affects their performance.

Innovation Solution

The atomizer design incorporates a top air-inlet structure with an airflow shell, an atomizing seat, and an oil-guiding seat, featuring air-inlet passages and an oil-guiding chamber that communicate with the atomizing chamber, ensuring proper oil volatilization and atomization, and includes additional components like an upper-cover assembly, sleeve assembly, and oil-absorbing elements to enhance performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a bottom air-inlet structure is used in the atomizer, then the structure is simple and easy to manufacture, but oil leakage occurs easily

Engineering Contradiction:
Improveease of manufactureVSAvoidoil leakage prevention
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent inverts the conventional bottom air-inlet structure to a top air-inlet structure. The airflow shell is positioned at the top with air-inlet passages, while the atomizing seat is at the bottom with the atomizing chamber. This inversion prevents oil from leaking through the air inlet while maintaining structural simplicity and ease of manufacture.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If a top air-inlet structure is used in the atomizer, then oil leakage is prevented, but the structure becomes more complex

Engineering Contradiction:
Improveoil leakage preventionVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple components into an integrated core assembly where the airflow shell, atomizing seat, and oil-guiding seat form a unified structure. The air-inlet passages are formed between the inner wall of the airflow shell and the outer wall of the atomizing seat, combining sealing and airflow functions in a single integrated design that reduces overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The airflow shell serves multiple functions: it provides the top air inlet structure to prevent oil leakage, forms air-inlet passages with the atomizing seat for controlled airflow, and contributes to the overall structural framework. This multi-functionality reduces the need for separate components, simplifying the overall structure while maintaining reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If air-inlet passages are formed between the airflow shell and atomizing seat, then atomizing performance is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveatomizing performanceVSAvoidease of manufacture
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent segments the core assembly into distinct functional parts: the airflow shell with air-inlet passages, the atomizing seat with atomizing chamber, and the oil-guiding seat. This segmentation allows each component to be manufactured separately with standard tolerances, then assembled to achieve the precise air-oil interaction needed for good atomizing performance without requiring ultra-precise single-piece manufacturing.

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure provides an atomizer and an electronic cigarette using same. The atomizer comprises a core assembly. The core assembly comprises an airflow shell, an atomizing seat partially accommodated in the airflow shell, and an oil-guiding seat connected with a part of the atomizing seat uncovered by the airflow shell. At least one air-inlet passage is formed between an inner wall of the airflow shell and an outer wall of the he atomizing seat. An atomizing chamber is defined inside the atomizing seat, and an oil-guiding chamber is defined inside the atomizing seat. The air-inlet passage and the oil-guiding chamber both communicate with the atomizing chamber. The atomizer of the present disclosure adopts a top air-inlet structure in order to solve the question of bottom oil leakage in the traditional electronic cigarette and has a better atomizing performance.
