Solution Overview

Problem

Existing atomizers for electronic cigarettes face issues with tobacco liquid leakage during transportation and storage due to the lack of effective sealing mechanisms.

Innovation Solution

An atomizer design featuring a detachable connection end with a sealing element and elastic element that seals the liquid outlet in a non-use state, allowing the tobacco liquid to flow into the atomizing assembly when connected and sealing it when detached, utilizing a spring and silicone stopper mechanism for controlled liquid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the atomizing assembly is detachably connected to the liquid supply, then the ease of operation is improved, but the reliability deteriorates due to potential liquid leakage during detachment

Engineering Contradiction:
Improvedetachable connectionVSAvoidliquid sealing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sealing element proactively seals the liquid outlet in the non-use state before any leakage can occur during detachment or transportation. This preliminary protective action prevents the harmful effect of liquid leakage while maintaining the detachable connection feature.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The sealing element dynamically changes its state based on the connection status: it seals the liquid outlet when the atomizing assembly is detached (non-use state) and opens the liquid outlet when the atomizing assembly is connected (use state). This dynamic adaptation resolves the contradiction between detachable connection and liquid sealing reliability.

Inventive Principle:
Principle #15Dynamics

2Loss of substance

If the sealing element seals the liquid outlet in non-use state, then the loss of substance is reduced, but the ease of operation worsens due to additional sealing mechanism complexity

Engineering Contradiction:
Improvetobacco liquid leakageVSAvoidstructure complexity
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The sealing element automatically performs the sealing function based on the connection status without requiring user intervention. The elastic element provides self-restoring force that activates the sealing mechanism automatically when the atomizing assembly is detached, reducing liquid loss while maintaining simple operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic element acts as an intermediary that translates the connection status into sealing action. It provides the restoring force that moves the sealing element between sealed and open states, achieving automatic sealing control with minimal structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the sealing element is positioned to seal the liquid outlet, then the reliability is improved, but the fluid flow is blocked in non-use state

Engineering Contradiction:
Improveliquid outlet sealingVSAvoidliquid flow
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The sealing element dynamically transitions between sealed and open positions based on the connection status. In the non-use state (detached), it seals the liquid outlet to prevent leakage. In the use state (connected), it opens the liquid outlet to allow tobacco liquid flow. This dynamic behavior resolves the contradiction between sealing reliability and liquid flow quantity.

Inventive Principle:
Principle #15Dynamics

AI summary

An exemplary atomizer (10) includes an atomizing assembly (200) and a liquid supply (100). The liquid supply includes a connection end (101). The atomizing assembly is detachably connected to the connection end. The connection end defines at least one liquid outlet (102), through which the tobacco liquid flows into the atomizing assembly. The atomizing assembly further includes a sealing element (103) and an elastic element (104). The sealing element is configured for sealing the liquid outlet when in a first position, and the elastic element abuts against the sealing element. When the atomizing assembly is connected with the liquid supply, the atomizing assembly is configured for driving the sealing element to move to a second position where the liquid outlet is opened. When the atomizing assembly is detached from the liquid supply, the atomizing assembly is configured for driving the sealing element to return to the first position where the sealing element seals the liquid outlet.
