Atomizer End Cover Sliding Seal for Refillable E-Cigarettes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current atomizers for electronic cigarettes require complex operations for refilling tobacco liquid, leading to easy loss of the end cover and contamination of the mouthpiece, as they necessitate detaching the end cover for refilling.
Innovation Solution
An atomizer design featuring a movably arranged end cover with a reversible position that can be opened horizontally without detachment, utilizing an elastic element like a W-shaped spring to maintain the end cover in place and a sealing strip for secure liquid inlet operation, ensuring easy refilling and preventing liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the end cover is detached via thread screw or fastener for refilling, then the liquid storage component can be accessed, but the operation process becomes complex and the end cover is easy to lose
Solution Approach 1:
The end cover is segmented into a movable sealing portion and a fixed body portion. The sealing strip can slide independently within the end cover to open or close the liquid inlet, while the end cover itself remains attached to the atomizing body. This segmentation allows refilling without detaching the entire end cover, simplifying the operation process.
Solution Approach 2:
The end cover transitions from a static, permanently attached component to a dynamic structure with movable parts. The sealing strip is designed to slide horizontally within the end cover, enabling dynamic opening and closing of the liquid inlet. The elastic element provides dynamic restoring force to return the sealing strip to its initial position, creating a flexible refilling mechanism.
2Ease of operation
If the end cover is detached for refilling, then the liquid storage component is accessible, but the mouthpiece is easy to be contaminated by extraneous matters
Solution Approach 1:
The sealing function is segmented from the end cover body and assigned to a separate sealing strip. This allows the sealing strip to move and open the liquid inlet while the end cover body with the mouthpiece remains stationary and attached, preventing contamination of the mouthpiece during refilling operations.
Solution Approach 2:
The sealing strip acts as an intermediary component between the user's refilling action and the liquid storage component. It provides a controlled opening mechanism that allows liquid injection without requiring removal of the end cover, thereby protecting the mouthpiece from direct exposure to external contaminants.
3Object-affected harmful factors
If the end cover is kept attached to the atomizing body, then the mouthpiece is protected from contamination, but the liquid inlet cannot be opened for refilling
Solution Approach 1:
The sealing strip is designed with horizontal sliding capability within the end cover, creating a dynamic opening mechanism. When the user pushes the end cover horizontally, the sealing strip slides to open the liquid inlet, allowing refilling while the end cover remains attached to protect the mouthpiece.
Solution Approach 2:
The elastic element automatically returns the sealing strip to its initial sealed position after refilling, without requiring manual intervention to reset the mechanism. The system self-regulates the opening and closing of the liquid inlet through the elastic restoring force, simplifying the refilling operation.
4Reliability
If an elastic element is added to maintain end cover position, then liquid leakage is prevented, but the device structure becomes more complex
Solution Approach 1:
The elastic element provides automatic restoring force to return the sealing strip to its initial position after refilling. This self-resetting mechanism ensures reliable sealing without requiring additional control systems or manual intervention, maintaining simplicity while improving reliability.
Solution Approach 2:
The elastic element replaces complex mechanical locking or latching mechanisms with a simple elastic restoring force. This substitution maintains the end cover and sealing strip in their proper positions and ensures reliable sealing through elastic deformation rather than complex mechanical interlocking.

Function Achieved in This Case
Simplifies the refilling process by eliminating the need to detach the end cover, reducing the risk of loss and contamination, while maintaining a secure seal for smooth tobacco liquid injection.
Implementation Method 1
an elastic element, configured to supply an elastic force on the end cover opposite to a moving direction of the end cover, during that the end cover is moving from the first place to the second place
