Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic electronic cigarette atomizers face issues with liquid leakage, immersion, cumbersome liquid filling processes, and low utilization of cigarette liquid due to open liquid passing holes and air outlet channels, as well as the difficulty in replacing atomization cores without staining hands and the risk of air channel blockage from large granular cigarette liquid.
Innovation Solution
An ultrasonic electronic cigarette atomizer design that includes a liquid passing hole and air outlet channel control structure linked with the liquid filling hole, allowing for controlled opening and closing to prevent leakage, immersion, and easy atomization core replacement, along with a liquid recycling mechanism to reuse granular cigarette liquid, ensuring high utilization and low consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the liquid passing hole is kept open to connect the liquid bin with the ultrasonic atomization sheet, then liquid can be supplied to the atomization sheet, but liquid leakage or immersion of the ultrasonic atomization sheet occurs due to pressure in the liquid bin
Solution Approach 1:
The patent applies a dynamic control mechanism where the liquid passing hole is opened only during liquid filling operation and closed during normal atomization operation. This dynamic switching state allows the system to prevent liquid leakage while ensuring proper liquid supply when needed, resolving the contradiction between productivity and reliability.
2Ease of operation
If the air outlet channel is kept open for normal operation, then air can flow through the atomizer, but liquid leakage occurs when sucking the electronic cigarette with opened liquid filling hole
Solution Approach 1:
The patent implements dynamic control of the air outlet channel, closing it during liquid filling operation and opening it during normal atomization operation. This dynamic switching prevents liquid leakage through the air outlet channel while ensuring proper air flow for atomization, resolving the contradiction between ease of operation and reliability.
3Device complexity
If the atomization core is disposed inside the atomizer housing, then the structure is compact, but hands of the operator are easily stained with cigarette liquid when replacing the atomization core
Solution Approach 1:
The patent segments the atomization core from the atomizer housing by providing a removable atomization core assembly that can be easily detached and replaced. This segmentation allows the operator to replace the atomization core without direct contact with liquid-containing areas, maintaining compact structure while enabling clean replacement operation.
4Reliability
If multiple disassembly operations are required to replace the atomization core, then the structure is secure, but the replacement process becomes cumbersome
Solution Approach 1:
The patent segments the atomization core as a separate removable assembly from the atomizer housing, allowing it to be replaced as a single unit without multiple disassembly operations. This segmentation maintains secure attachment during use while enabling simple, quick replacement, resolving the contradiction between reliability and ease of operation.
5Ease of operation
If the liquid filling hole is exposed after unscrewing the bottom or top cover, then liquid can be filled into the liquid bin, but cigarette liquid easily flows out through the liquid filling hole causing waste and pollution
Solution Approach 1:
The patent implements dynamic control where the liquid filling hole is opened only during the liquid filling operation and automatically closed afterward. This dynamic switching allows easy liquid filling access while preventing cigarette liquid from flowing out and causing waste or pollution, resolving the contradiction between ease of operation and loss of substance.
6Device complexity
If large granular cigarette liquid is not recycled, then the atomization process is simple, but the air channel is easily blocked and cigarette liquid consumption is high
Solution Approach 1:
The patent implements a liquid recycling mechanism that collects large granular cigarette liquid from the atomization process and returns it to the liquid bin for reuse. This recovering approach reduces cigarette liquid consumption and prevents air channel blockage while maintaining relatively simple atomization process, resolving the contradiction between device complexity and loss of substance.

AI summary
An ultrasonic electronic cigarette atomizer is disclosed, including an atomization core, an atomizer housing, and a liquid bin. When liquid is filled into the liquid bin, the liquid passing hole is closed and the air outlet channel is closed, to avoid leakage or immersion of liquid, the atomizer is clean and sanitary, waste is avoided, and cost is saved. The whole operation is very simple, the atomization core is convenient to replace, hands are not stained with liquid, and the liquid is convenient to fill. The cigarette liquid is unlikely to flow out through the liquid filling hole, and large granular cigarette liquid generated in atomization can be recycled.
