Solution Overview

Problem

During the replacement of the atomizing core in electronic cigarettes, e-liquid often leaks from the atomizing device, disrupting normal use and user experience.

Innovation Solution

An atomizing device with a sealing mechanism comprising a return spring and liquid stopper that seals the e-liquid hole when the atomizing core is removed, preventing leakage by using the elastic force of the return spring to keep the liquid stopper in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the atomizing core is made replaceable for user convenience, then ease of operation is improved, but e-liquid leakage occurs during replacement

Engineering Contradiction:
Improveease of atomizing core replacementVSAvoide-liquid containment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The liquid stopper is pre-positioned within the atomizing sleeve, ready to seal the e-liquid hole before the atomizing core is removed. This preliminary sealing action prevents e-liquid leakage from occurring during the replacement process, allowing users to replace cores without worrying about spills.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The liquid stopper acts as an intermediary component between the e-liquid reservoir and the external environment. It mediates the potential leakage issue by providing a controllable seal that can be opened when needed (during normal operation) and closed during core replacement, thus protecting against e-liquid spillage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the e-liquid hole remains open for normal atomization, then atomization function is improved, but e-liquid leaks during core removal

Engineering Contradiction:
Improveatomization functionVSAvoide-liquid leakage
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The liquid stopper is designed to be dynamically movable rather than fixed. It can shift position based on the presence or absence of the atomizing core - remaining open during normal atomization to allow e-liquid flow, and closing automatically when the core is removed to prevent leakage. This dynamic behavior resolves the contradiction between maintaining atomization function and preventing leakage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the state parameter of the e-liquid hole from open to closed based on whether the atomizing core is installed. The liquid stopper responds to the core's presence by adjusting the hole's openness, thereby enabling normal atomization when needed while preventing leakage during core replacement operations.

AI summary

The disclosure discloses an atomizing device (100) for an electronic cigarette and an electronic cigarette having the same. The atomizing device includes: an atomizing sleeve (11) defining an e-liquid hole (113); an atomizing core (12) removably arranged in the atomizing sleeve; and a sealing mechanism (13) including a return spring (131) and a liquid stopper (132), the liquid stopper connected to the atomizing sleeve via the return spring and configured to seal the e-liquid hole. When the atomizing core is inserted into the atomizing sleeve, the liquid stopper is configured to be pushed to overcome an elastic force of the return spring to open the e-liquid hole; and when the atomizing core is removed from the atomizing sleeve, the liquid stopper is configured to seal the e-liquid hole under the elastic force of the return spring.
