Atomizer Snap-Fit Sealing Layer Piercing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes experience unsatisfactory user experience due to tobacco liquid leakage during the assembly process, where the atomizing component needs to be screwed multiple turns to achieve a hermetic seal, leading to liquid leakage through screw threads.
Innovation Solution
An atomizer design featuring a liquid supply with a sealing layer and an atomizing component that uses a snap-fit mechanism, incorporating a piercing element, buffer chamber, and atomizing unit, which pricks the sealing layer to direct tobacco liquid into the buffer chamber, preventing leakage by ensuring a tight seal through a sealing ring and check valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizing component is screwed multiple turns to achieve hermetic seal, then the sealing reliability is improved, but the tobacco liquid leakage through screw threads occurs during assembly
Solution Approach 1:
The piercing element is pre-configured in the atomizing component to automatically pierce the sealing layer when the atomizing component is engaged with the liquid supply. This preliminary action ensures the liquid pathway is opened before any leakage can occur during the assembly process, eliminating the need for multiple screw turns while preventing liquid leakage.
Solution Approach 2:
A sealing layer is introduced as an intermediary element between the liquid supply and the atomizing component. This sealing layer is designed to be pierced by the piercing element, creating a controlled liquid pathway while maintaining hermetic sealing through the snap-fit connection. The sealing layer acts as a mediator that enables both liquid flow and leak prevention.
2Ease of operation
If the atomizing component is detachably coupled by snap fit, then the ease of operation is improved, but the hermetic seal may be compromised
Solution Approach 1:
The piercing element is pre-configured to automatically pierce the sealing layer during the snap-fit engagement process itself, rather than requiring separate actions. This ensures that the liquid pathway is opened and the hermetic seal is maintained simultaneously through the single snap-fit operation, achieving both ease of operation and sealing reliability.
Solution Approach 2:
The sealing layer serves as an intermediary that is designed to be pierced by the piercing element during snap-fit engagement. This intermediary element enables the detachable coupling to maintain hermetic seal by providing a controlled pathway that opens only when properly engaged, combining ease of operation with reliable sealing.
3Productivity
If the piercing element pricks the sealing layer immediately upon engagement, then the liquid flow is initiated quickly, but the liquid may leak before the seal is established
Solution Approach 1:
The piercing element is positioned and oriented such that it pierces the sealing layer at the exact moment when the snap-fit connection establishes the hermetic seal. This synchronized preliminary action ensures that the liquid pathway is opened only after the seal is secure, achieving quick liquid flow initiation without leakage.
Solution Approach 2:
The sealing layer acts as a controlled intermediary that is pierced only when the snap-fit connection is properly established. The design ensures that the piercing action and seal establishment occur simultaneously, allowing quick liquid flow initiation while preventing leakage by maintaining seal integrity during the transition.
