The device incorporates a capillary-driven liquid storage groove and liquid guiding grooves to absorb and redirect condensate back to the atomizing member, utilizing a stepped structure and capillary forces to minimize leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If e-liquid is heated for atomization, then vapor is produced for user consumption, but incompletely atomized e-liquid and condensate form causing suction liquid leakage

Engineering Contradiction:

Improveatomization efficiencyVSAvoidliquid leakage control

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent converts the harmful condensate that causes leakage into a beneficial resource by channeling it back to the atomizing member through the liquid guiding cotton and liquid guiding groove, where it is re-used for atomization, thus eliminating waste and preventing leakage simultaneously

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The liquid guiding cotton acts as an intermediary component between the air outlet channel and the atomizing member, transporting condensate through capillary action and guiding it back to where it can be re-used, serving as a mediator that resolves the contradiction between atomization efficiency and leakage control

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If condensate is collected in the air outlet channel, then liquid leakage is reduced, but e-liquid utilization rate decreases due to waste

Engineering Contradiction:

Improveliquid leakage controlVSAvoide-liquid utilization

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

Instead of discarding the condensate that accumulates in the air outlet channel, the patent recovers it by guiding it back to the atomizing member through the liquid guiding structure, allowing re-use of the e-liquid and preventing both leakage and waste simultaneously

Inventive Principle:

Principle #34Discarding and recovering

AI summary

An atomizer and an electronic atomizing device. The atomizer includes an atomizing member, an airflow channel, and a liquid storage groove. The atomizing member includes a cylindrical atomizing core and a liquid guiding cotton surrounding the atomizing core. The airflow channel includes an air outlet channel. The liquid storage groove is disposed on the air outlet channel for absorbing condensate by capillary force. A liquid returning structure is arranged on a bottom of the liquid storage groove to make the liquid storage groove be in fluid connection to the liquid guiding cotton for guiding liquid. The liquid returning structure is a stepped structure including a bottom wall and a top wall; a top end of the liquid guiding cotton abuts against the top wall and a side surface of the liquid guiding cotton abuts against the bottom wall.
