Solution Overview

Problem

Electronic atomizers face issues such as liquid leakage, leading to waste and contamination of components, and unsmooth liquid supply causing dry burning and overheating, due to air pressure imbalances and high atomization speeds.

Innovation Solution

The atomizer incorporates an air-liquid equilibrium element with capillary function, featuring liquid storage grooves and an air backflow groove, along with a surface tension isolation groove, to balance air pressure and prevent leakage by managing liquid flow and supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the atomization speed of liquid medium is increased, then the atomization efficiency is improved, but the liquid supply becomes unsmooth causing dry burning and overheating

Engineering Contradiction:
Improveatomization efficiencyVSAvoidliquid supply stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The liquid storage grooves pre-store liquid medium before atomization occurs. This preliminary storage ensures that when high-speed atomization demands rapid liquid supply, the pre-stored liquid in the grooves can immediately replenish the atomization element, preventing dry burning and maintaining supply stability during high-productivity operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The air backflow groove provides beforehand cushioning by allowing air to flow backward and balance pressure differences that occur during rapid atomization. This pressure balancing prevents liquid supply interruptions and ensures continuous stable liquid delivery even when atomization speed increases to improve productivity

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Quantity of substance

If the liquid storage capacity is increased, then the liquid supply duration is extended, but the air pressure balance is disrupted causing liquid leakage

Engineering Contradiction:
Improveliquid storage capacityVSAvoidair pressure balance
Core Design Contradiction:
Quantity of substanceVSStress or pressure

Solution Approach 1:

The air backflow groove acts as an intermediary mechanism between the liquid storage grooves and the external environment. It mediates pressure changes by allowing controlled air flow that balances internal pressure, enabling increased liquid storage capacity without disrupting pressure equilibrium and preventing liquid leakage

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The air backflow groove provides feedback control for pressure balance. When liquid storage increases and creates pressure imbalance, the backflow groove responds by allowing air to flow in a direction that restores pressure equilibrium, creating a self-regulating system that maintains balance despite varying liquid quantities

Inventive Principle:
Principle #23Feedback
