Electronic Cigarette Top Cover Locking for Reliable Nozzle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarettes face issues with unreliable connection between the suction nozzle and housing, poor operational convenience, low key PC board trigger efficiency, and frequent mouth scalding due to high smoke temperature.
Innovation Solution
An electronic cigarette design featuring a top cover with a clamping rib and locking mechanism for secure suction nozzle attachment, an elastic mechanism for easy top cover opening, and a linkage block with a second spring for concentrated force application to enhance key PC board triggering, along with an atomization assembly and temperature regulation system to prevent scalding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the suction nozzle is connected to the housing by thread tightening, then the connection can be assembled, but the threads are easily worn to cause slipping, making the connection unreliable
Solution Approach 1:
The connection structure is divided into a suction nozzle with an external thread and a housing with an internal thread, allowing separate assembly and disassembly while maintaining reliable connection through threaded engagement
Solution Approach 2:
The thread structures are pre-formed on the suction nozzle and housing during manufacturing, enabling direct screw connection without additional processing or preparation steps
2Ease of operation
If the side panel of the housing is used as the key shell to increase contact area, then finger comfort is improved, but the key shell is easily deformed and deflected due to non-uniform force, reducing operational reliability
Solution Approach 1:
The key shell is separated from the housing as an independent component with a dedicated key pressing structure, concentrating the pressing force on a specific key pressing portion rather than distributing it across the entire side panel, thus preventing deformation while maintaining operational comfort
Solution Approach 2:
The key shell features a localized key pressing portion with optimized geometry and material properties specifically designed to transmit force efficiently to the key PC board without deforming the overall structure
3Ease of operation
If the top cover is opened to access the housing, then component replacement is enabled, but the connection between suction nozzle and housing becomes disconnected
Solution Approach 1:
The top cover assembly is separated from the housing, allowing the top cover to be opened for component access while the suction nozzle remains securely connected to the housing through its dedicated threaded connection, maintaining connection stability during maintenance operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable, convenient, and efficient connection between components, improves key PC board trigger efficiency, reduces the risk of mouth scalding, and enhances user experience by stabilizing the atomization process and temperature control.
Implementation Method 1
an elastic mechanism for opening the top cover when the locking mechanism is separated from the clamping rib is also disposed in the housing
Implementation Method 2
the elastic mechanism includes a torsion spring between the support and the housing, and the torsion spring is sleeved outside the rotating shaft
Implementation Method 3
the locking mechanism includes a key handle, a transmission and a first spring
