Electronic Cigarette Atomizing Assembly Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes face the risk of e-liquid leakage due to the continuous communication between the atomizing core and the e-liquid storage tank, which is not effectively addressed in existing designs.
Innovation Solution
The electronic cigarette design separates the atomizing core from the e-liquid storage tank when not in use, using a seal ring and first fixed seat to completely seal the e-liquid inlet, and allows exposure under external force for e-liquid flow when in use, with the atomizing assembly mounted on the battery assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizing core continuously communicates with the e-liquid storage tank, then e-liquid flow is ensured, but e-liquid leakage risk increases
Solution Approach 1:
The atomizing core is designed to move dynamically between two positions: a first position where it communicates with the e-liquid storage tank for atomization, and a second position where it is separated from the tank to prevent leakage. This dynamic positioning resolves the contradiction by allowing the system to switch between flow reliability and leakage prevention based on operational state
Solution Approach 2:
A blocking component is introduced as an intermediary element that can occlude the communication passage between the atomizing core and the e-liquid storage tank. This mediator allows the system to control e-liquid flow by blocking or unblocking the passage, thereby preventing leakage while maintaining the ability to ensure flow when needed
2Volume of moving object
If the atomizing assembly is integrated with the battery assembly, then device size is reduced, but assembly complexity increases
Solution Approach 1:
The electronic cigarette is divided into separable modules: an atomizing assembly and a battery assembly. The atomizing assembly can be easily attached to or detached from the battery assembly, allowing the device to maintain a compact integrated form during use while simplifying assembly and replacement processes through modular design
3Object-affected harmful factors
If the atomizing core is sealed when not in use, then e-liquid leakage is prevented, but e-liquid flow is blocked
Solution Approach 1:
The communication passage between the atomizing core and e-liquid storage tank is designed to be dynamically controllable. When not in use, the passage is sealed to prevent leakage; when in use, the passage is opened to allow e-liquid flow. This dynamic control resolves the contradiction by switching the sealing state based on operational requirements
Solution Approach 2:
The system automatically controls the sealing and opening of the communication passage based on its operational state. The atomizing assembly's movement between positions automatically triggers the sealing or opening of the passage, eliminating the need for separate control mechanisms and ensuring reliable flow when needed while preventing leakage when not in use
