Solution Overview

Problem

Current electronic cigarette atomizers allow non-atomized liquid tobacco to flow into the user's mouth, which is undesirable.

Innovation Solution

The atomizer design includes a liquid storing member that acts as a stopper when liquid tobacco is insufficiently atomized, directing small smoke droplets to exit from both sides of the atomizing head, preventing their inhalation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the atomizing head uses a simple air outlet channel at the top, then the structure is simple, but liquid tobacco can flow directly into the user's mouth

Engineering Contradiction:
Improveatomizing head structureVSAvoidliquid tobacco entering mouth
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The air outlet is segmented into multiple channels: a top air outlet channel and side air outlet channels. The liquid outlet is also segmented with a main liquid outlet and side liquid outlets. This segmentation prevents liquid tobacco from reaching the top air outlet while maintaining simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The atomizing cavity acts as an intermediary space between the liquid outlet and the air outlet. Liquid tobacco flows through the atomizing cavity where it is atomized before potentially entering the air outlet, preventing direct liquid flow to the user's mouth.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the liquid outlet is positioned at the top of the atomizing head, then liquid delivery is direct, but non-atomized liquid can be inhaled

Engineering Contradiction:
Improveliquid delivery efficiencyVSAvoidnon-atomized liquid inhalation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The liquid outlet is divided into a main liquid outlet at the top and side liquid outlets positioned lower on the atomizing head. This segmentation allows liquid to be delivered efficiently through the main outlet while the side outlets provide backup liquid supply that prevents non-atomized liquid from reaching the top air outlet.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution moves from a single vertical liquid outlet to a multi-dimensional liquid delivery system with outlets at different heights and positions (top and sides), preventing liquid from directly reaching the top air outlet while maintaining delivery efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the atomizing head has only a top air outlet, then the structure is simple, but liquid tobacco may flow out from the top

Engineering Contradiction:
Improveair outlet configurationVSAvoidliquid tobacco flow from top
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The air outlet is segmented into a top air outlet channel and side air outlet channels. The liquid outlet is also segmented with side liquid outlets positioned to prevent liquid from reaching the top air outlet, maintaining simple structure while preventing harmful liquid flow.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Prevents the inhalation of non-atomized liquid tobacco droplets by ensuring they are released from the sides of the atomizing head, enhancing user safety and experience.

Implementation Method 1

The main function of the atomizing head is to heat and atomize the liquid tobacco. When heated, the liquid tobacco makes smoke.

Methodology Applied
Scientific EffectVaporization: Evaporation

Implementation Method 2

at least one liquid inlet groove communicating with the liquid outlet is defined on the sidewall of the atomizing head base along the axial direction of the atomizing head base

Methodology Applied
Scientific EffectFluid flow:

AI summary

An atomizer comprises an outer tube, a liquid storing member received in the outer tube, and an atomizing head located at the lower portion of the liquid storing member. A liquid storing cavity is formed in the liquid storing member. An air outlet channel is formed between the outer tube inner wall and the liquid storing member outer wall. An atomizing cavity communicating with the liquid storing cavity and the air outlet channel is formed in the atomizing head. When the liquid tobacco absorbed by the atomizing head is insufficiently atomized, the liquid storing member above the atomizer head acts as a stopper, small smoke droplets can only be released from both sides of the atomizing head, preventing user inhalation of non-atomized liquid. An electronic cigarette having the atomizer is also provided.
