Solution Overview

Problem

Traditional atomization devices lack an isolation structure between the e-liquid stored in the e-liquid cup and the atomization assembly, leading to potential e-liquid leakage due to vibrations during transportation or external factors, which can cause the e-liquid to seep into the atomization assembly.

Innovation Solution

An e-liquid core separation structure is introduced, featuring a first and second chamber in the e-liquid cup body, with a controllable e-liquid inlet hole connecting them, and an e-liquid inlet switch to manage the flow between these chambers, ensuring the atomization assembly remains isolated from direct e-liquid contact, even if leakage occurs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If no isolation structure is provided between e-liquid cup and atomization assembly, then device structure is simple, but e-liquid leakage occurs during transportation or external vibrations

Engineering Contradiction:
Improvestructure simplicityVSAvoide-liquid leakage prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The e-liquid cup is segmented into a first chamber (storage chamber) and a second chamber (atomization chamber) separated by a partition wall. The first chamber stores e-liquid while the second chamber supplies it to the atomization assembly, preventing direct contact between bulk e-liquid and the atomization assembly, thus solving the leakage problem during transportation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition wall acts as an intermediary barrier between the e-liquid storage space and the atomization assembly. It allows controlled e-liquid flow through the e-liquid inlet hole while preventing uncontrolled leakage, serving as a mediator that maintains both structural simplicity and leakage prevention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If e-liquid inlet hole is always open for continuous supply, then atomization assembly is continuously supplied, but e-liquid leaks into atomization assembly during vibration

Engineering Contradiction:
Improvee-liquid supply continuityVSAvoidleakage resistance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The e-liquid inlet hole is designed to be dynamically controllable rather than permanently open. The switch mechanism allows the inlet hole to be opened when e-liquid supply is needed and closed during transportation or when the cup is full, adapting the system's state to different operational conditions and preventing leakage while maintaining supply continuity.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If e-liquid cup is depleted, then device cannot function, but user may not notice until atomization core burns

Engineering Contradiction:
Improveuser awarenessVSAvoidatomization core protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The partition wall structure provides visual feedback by allowing users to observe e-liquid levels in the first chamber. When the e-liquid level drops below a certain threshold, users can visually detect this and refill the device, preventing the atomization core from burning due to e-liquid depletion.

Inventive Principle:
Principle #23Feedback

AI summary

The present application discloses an e-liquid core separation structure, an atomization device, and atomization equipment, relating to the field of atomization technology. The e-liquid core separation structure includes an e-liquid cup body, an atomization assembly, and an e-liquid inlet switch. The atomization assembly is mounted in the e-liquid cup body. The e-liquid cup body is provided with a first chamber, a second chamber, a first e-liquid inlet hole, and a second e-liquid inlet hole. The first chamber is used for storing e-liquid and is communicated with the second chamber through the first e-liquid inlet hole. The second chamber is communicated with the e-liquid storage cotton of the atomization assembly through the second e-liquid inlet hole. The e-liquid inlet switch is mounted in the e-liquid cup body and is used to open or close the first e-liquid inlet hole. The multi-chamber design ensures that any leaked e-liquid enters the second chamber without directly contacting the atomization assembly, thereby further enhancing the sealing effect. Additionally, it effectively prevents the anxiety of dry burning when the e-liquid in the first chamber is depleted.
