Locking Safety Cover for E-Cig Atomizer Prevents Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing thread connection mechanism in electronic cigarette atomizers is prone to accidental unscrewing, leading to leakage and potential detachment of the upper cover, compromising the sealing and functionality of the device.
Innovation Solution
A locking safety cover with a concave and convex block mechanism is introduced, allowing for joint or independent rotation between components, ensuring unidirectional locking to prevent accidental unscrewing and enhancing the sealing integrity of the atomizer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thread connection mechanism is used to attach the upper cover to the atomizer body, then the device structure is simple and easy to manufacture, but the connection is prone to accidental unscrewing leading to leakage and detachment
Solution Approach 1:
The locking block is pre-positioned on the connecting component, and the locking groove is pre-formed on the fixed component. When the components are assembled, the locking block automatically engages with the locking groove, creating a preliminary locked state that prevents accidental unscrewing while maintaining simple assembly procedures
Solution Approach 2:
The locking block and locking groove act as intermediary elements between the thread connection mechanism and the fixed component. This intermediary locking mechanism enhances connection reliability by preventing accidental detachment, while the overall structure remains relatively simple as it builds upon the existing thread connection framework
2Ease of operation
If the upper cover is allowed to rotate independently for easy assembly, then the ease of operation is improved, but the sealing integrity may be compromised
Solution Approach 1:
The connecting component is designed to transition from a dynamic state (independent rotation during assembly) to a static locked state (joint rotation during operation). The locking mechanism allows the connecting component to rotate independently when being screwed onto the atomizer body, but once the locking block engages with the locking groove, it transitions to a fixed state that maintains sealing integrity during use
Solution Approach 2:
The locking block is pre-positioned to engage with the locking groove at the appropriate moment during assembly. This preliminary engagement action ensures that once the connecting component is screwed onto the atomizer body, the locking mechanism automatically secures the connection, maintaining both ease of assembly and sealing integrity

AI summary
The present invention is intended to provide a thread-locking device which can prevent a thread from being screwed off by accident in a thread connection situation. Said thread-locking device comprises a circular fixing component (1), a circular rotary component (2), and a circular connecting component (4). Said circular fixing component and circular connecting component are fixedly connected, said circular rotary component is set between the circular fixing component and the circular connecting component, and said circular rotary component can rotate around the axis of the thread-locking device and slide along said axis. A concave and a convex block locking mechanism (21,41) is set on the end faces of the circular rotary component and the circular connecting component so that a joint rotation state and an independent rotation state exist between the circular connecting component and the circular rotary component. The above mentioned device can be used as a safety cover of an electronic cigarette atomizer to prevent a thread from being screwed off by accident in a thread connection situation, so that the liquid leaks out of the upper cover or even the upper cover falls off.
