Solution Overview

Problem

Existing electronic aerosol generation devices face issues such as inconsistent atomization taste, potential health risks from inhaling condensed liquid, and damage to circuit components due to liquid leakage. Additionally, the side injection of liquid in current designs leads to oil and liquid leakage problems.

Innovation Solution

The proposed solution involves an atomizer design with a shell, a fixing component, and an atomizing component. The atomizing component includes a liquid conducting member with a longitudinal air guide hole and liquid guide grooves, which facilitate efficient liquid and air flow, preventing condensation and leakage. The liquid is injected from the top, reducing leakage risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the atomizing liquid permeates from the liquid-conducting surface to the atomization surface through a long path, then the liquid can be adequately supplied to the heating element, but the aerosol flow path becomes long causing taste alteration due to cooling and condensation

Engineering Contradiction:

Improveliquid supply reliabilityVSAvoidaerosol taste alteration and condensation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the liquid injection direction from side injection to top injection, and repositions the air guide hole to the bottom of the liquid conducting member. This dimensional reconfiguration creates a shorter aerosol flow path while maintaining adequate liquid supply through the liquid guide grooves, thereby reducing cooling effects and condensation in the aerosol flow path.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent inverts the traditional structure by placing the air guide hole at the bottom rather than the top, and injecting liquid from the top rather than the side. This inversion optimizes the aerosol generation path, allowing hot aerosol to rise directly from the atomization surface to the air guide tube, minimizing cooling and condensation.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If liquid is injected from the side in the current atomizing core design, then the liquid can reach the atomization surface, but the assembly requires additional sealing parts and is prone to oil and liquid leakage

Engineering Contradiction:

Improveliquid delivery functionVSAvoidassembly complexity and leakage risk

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent inverts the liquid injection approach from side injection to top injection. The liquid conducting member receives liquid from the top through the liquid guide grooves, eliminating the need for complex side sealing structures. This top injection design simplifies the assembly and reduces leakage risks while maintaining reliable liquid delivery to the atomization surface.

Inventive Principle:

Principle #13The other way round (Inversion)

3Temperature

If the atomizing liquid is not fully vaporized by the heating element, then the heating element may overheat, but the liquid may seep or drip out of the atomizing core and damage circuit components

Engineering Contradiction:

Improveheating element temperature controlVSAvoidliquid seepage and circuit damage

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent introduces the liquid guide grooves as an intermediary structure between the liquid conducting member and the atomization surface. These grooves ensure controlled liquid distribution to the heating element, promoting complete vaporization and preventing liquid accumulation that could lead to seepage and circuit damage, while also preventing overheating through adequate liquid supply.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present invention discloses an electronic aerosol generation device and atomizer thereof, the atomizer comprises a shell, a fixing component, and an atomizing component. The atomizing component comprises a liquid conducting member and a heating element. The liquid conducting member is provided with an air guide hole running through itself longitudinally, and a liquid guide groove. The liquid guide groove may include a first sub-liquid guide groove and a second sub-liquid guide groove in communication with the first sub-liquid guide groove. The first sub-liquid guide groove is in communication with a liquid guide channel. The aerosol generated by the atomizing component can directly enter the air guide tube through the air guide hole, with a short flow path. The liquid conducting member injects liquid from the top, which is less prone to oil and liquid leakage compared to injecting liquid from the side.
