Solution Overview

Problem

Existing atomizing electronic cigarettes suffer from poor atomization, large liquid drops in the final atomized smoke, nonuniform smoke due to varying liquid drop sizes, excessive moisture, and poor mouthfeel, which differ significantly from real cigarettes.

Innovation Solution

An improved atomizing electronic cigarette design featuring a liquid permeating component sleeved on an electric heater, with cigarette liquid stored in a liquid storage component that permeates into the atomizer, ensuring smaller and more uniform droplets. Additionally, airflow communication through holes and channels in the electric heater and liquid storage component helps adhere larger drops to the storage component, mimicking the feel of real cigarettes.

Engineering Contradictions & Design Principles

1Manufacturing precision

If traditional atomizing electronic cigarette design is used, then the device structure is simple, but the atomization quality is poor with large and nonuniform liquid drops

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The atomizing core component is divided into multiple functional layers: a liquid permeating component with porous structure for liquid distribution, an electric heater for vaporization, and a liquid storage component for liquid reservoir. This segmentation allows each component to optimize its function, resulting in uniform droplet atomization while maintaining reasonable structural complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The liquid permeating component is sleeved on the electric heater, forming a nested structure where the heater is positioned inside the porous component. The liquid storage component is further nested to communicate with the permeating component through channels. This nested arrangement achieves compact design with improved atomization uniformity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 1:

The liquid permeating component uses porous material with specific pore size distribution to control liquid flow locally. The electric heater is positioned to provide localized heating zones, ensuring optimal vaporization temperature and moisture control, thereby improving mouthfeel

Inventive Principle:

AI summary

An atomizing electronic cigarette has an atomizing core component and a liquid storage component. including an electric heater. The electric heater may have a through hole aligned with a channel passing through the liquid storage component. The cigarette can heat and uniformly vaporize liquid from the liquid storage component, with the user inhaling the vaporized liquid. The vapor generated by the atomizing process may be cooled as it flows through the channel.
