Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

E-liquid electronic cigarettes experience oil leakage during long-term placement and transportation due to constant communication between the oil chamber and the heat generating component, leading to liquid contamination and loss.

Innovation Solution

An atomizer with an oil locking function is designed, featuring an inner wall composed of a fixing component and a rotating component in a rotating fit, which aligns or offsets oil locking and guiding holes to block or allow oil flow, using multiple sealing rings and a microporous ceramic heating tube for efficient sealing and heating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the oil passage between the oil chamber and the heat generating component is always in a communication state, then the e-liquid can be continuously supplied to the heat generating component for vaporization, but oil leakage occurs during long-term placement and transportation

Engineering Contradiction:

Improvecontinuous oil supplyVSAvoidoil leakage prevention

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies the dynamics principle by making the oil passage dynamic rather than static. The rotating component with the oil locking hole can rotate between two positions: in the first position, the oil locking hole aligns with the oil guiding hole to enable oil flow; in the second position, the holes are staggered to block oil flow. This dynamic adjustment allows the system to switch between continuous supply mode and leakage prevention mode, resolving the contradiction between productivity and reliability.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the oil locking hole and oil guiding hole are aligned, then oil can flow from the oil chamber to the heat generating component, but oil leakage occurs when the device is placed or transported

Engineering Contradiction:

Improveoil flow controlVSAvoidoil leakage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The rotating component enables dynamic control of the oil passage by rotating between alignment and staggered positions. This dynamic mechanism allows the user to easily control oil flow by simply rotating the component, while effectively preventing leakage when in the blocked position.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotating component acts as an intermediary mechanism between the oil chamber and the heat generating component. By introducing this intermediate element with rotatable oil locking hole, the system gains precise control over oil flow, enabling easy operation while preventing harmful leakage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multiple sealing rings are added to prevent oil leakage, then oil leakage is reduced, but the device complexity increases

Engineering Contradiction:

Improvesealing performanceVSAvoidnumber of sealing components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the sealing function into multiple segments by placing sealing rings at different locations: first and second sealing rings between the fixing component and rotating component, third sealing ring between cigarette liquid tube and oil locking ring, and fourth sealing ring between cigarette liquid tube and cigarette holder. This segmentation approach distributes the sealing responsibility across multiple points, improving overall reliability while keeping each individual sealing element simple.

Inventive Principle:

Principle #1Segmentation

Function Achieved in This Case

Prevents oil leakage during storage and transport by completely blocking the connection between the e-liquid and the outside world when not in use, keeping the liquid fresh and allowing easy refilling and smoking by aligning the holes when needed.

AI summary

An atomizer with an oil locking function includes a cigarette holder and an atomizer body provided with an oil chamber. An inner wall of the oil chamber is composed of a fixing component and a rotating component that are in a rotating fit. The fixing component is provided with an oil guiding hole and is connected to the cigarette holder. The rotating component includes a first rotation angle causing the oil locking hole and the oil guiding hole to be aligned with each other, and a second rotational angle causing the oil locking hole and the oil guiding hole to be mutually staggered from each other.
