Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic electronic cigarette atomizers suffer from e-liquid leakage issues when the atomization core is disassembled or when adding e-liquid, leading to poor user experience and inefficient atomization.
Innovation Solution
An ultrasonic electronic cigarette atomizer design that includes a moving assembly within the e-liquid storage assembly to control the e-liquid outlet, ensuring it is closed during disassembly and e-liquid addition, and an upper cover assembly to misalign the e-liquid outlet when adding e-liquid, preventing leakage and ensuring proper operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the e-liquid outlet is kept open for easy access, then e-liquid can be easily added to the chamber, but e-liquid leakage occurs when the atomization core is disassembled or during e-liquid addition
Solution Approach 1:
The patent applies a moving assembly that can dynamically change the state of the e-liquid outlet between open and closed positions. The moving member responds to the assembly/disassembly state of the atomization core, automatically opening the outlet when needed for e-liquid addition and closing it when the core is removed, thus preventing leakage while maintaining ease of operation.
2Ease of operation
If the atomization core is easily detachable for maintenance, then user convenience is improved, but e-liquid leakage occurs during disassembly
Solution Approach 1:
The moving assembly is designed to automatically close the e-liquid outlet in advance when the atomization core is removed. This preliminary closing action prevents e-liquid leakage before the user completes the disassembly process, allowing users to easily detach the core for maintenance without worrying about leakage.
3Ease of operation
If the e-liquid outlet remains open during e-liquid addition, then refilling is convenient, but the ultrasonic atomization sheet becomes immersed in e-liquid causing slow atomization start
Solution Approach 1:
The moving assembly dynamically adjusts the e-liquid outlet state during the refilling process. When the atomization core is inserted for refilling, the outlet opens to allow e-liquid addition. After refilling, when the core is fully assembled, the outlet automatically closes to prevent the atomization sheet from being immersed in excess e-liquid, thereby ensuring fast atomization start speed.
