Innovation Solution
A control method for electronic cigarettes that includes a detecting device, a heating member, a liquid absorbing member, and a pump body, where the detecting device monitors the saturation of the liquid absorbing member and the controller adjusts the operation of the pump and heating member based on predefined threshold values to prevent saturation and reduce the risk of leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pump body continuously supplies cigarette liquid to the heating member, then the productivity of the electronic cigarette is improved, but the liquid absorbing member may reach saturation and cause liquid leakage
Solution Approach 1:
The patent implements a feedback control mechanism where the first detecting device continuously monitors the saturation degree of the liquid absorbing member and sends signals to the controller. The controller adjusts the pump body's liquid supply based on this feedback, stopping supply when saturation is detected. This closed-loop control resolves the contradiction by enabling high productivity during normal operation while preventing liquid leakage through real-time monitoring and automatic adjustment.
Solution Approach 2:
The patent applies preliminary action by detecting the saturation degree of the liquid absorbing member before liquid leakage actually occurs. The first detecting device monitors the saturation level in advance, and the controller preemptively stops liquid supply when the saturation threshold is approached, preventing the harmful effect of liquid leakage before it happens while maintaining continuous operation during safe conditions.
2Reliability
If the liquid absorbing member absorbs excess cigarette liquid, then the reliability against liquid leakage is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent applies multi-functionality by designing the liquid absorbing member to serve dual purposes: it absorbs excess cigarette liquid to prevent leakage, and simultaneously acts as a sensor platform for the first detecting device to monitor saturation levels. The controller integrates multiple control functions (pump control, heating control, and saturation monitoring) into a single unit. This approach improves reliability while minimizing device complexity by making components perform multiple functions.
3Productivity
If the heating member heats the cigarette liquid rapidly, then the productivity is improved, but the liquid may not be atomized in time and causes leakage
Solution Approach 1:
The patent uses feedback control to coordinate the heating member's operation with the liquid supply and absorption rates. The controller receives saturation degree feedback from the first detecting device and adjusts the heating member's operation accordingly, ensuring that heating speed matches the liquid supply rate and absorption capacity, thereby maintaining high productivity while preventing incomplete atomization and leakage.
Solution Approach 2:
The patent applies dynamics by making the heating member's operation adjustable rather than fixed. The controller dynamically modifies the heating member's working state based on real-time saturation feedback, increasing heating power when liquid supply is high and decreasing it when the liquid absorbing member approaches saturation. This dynamic adjustment resolves the contradiction by adapting heating speed to actual system conditions.

AI summary
An electronic cigarette has an atomizing assembly that includes a first detecting device, a heating member for heating cigarette liquid, a liquid absorbing member for adsorbing excess cigarette liquid, a controller, and a pump body, which delivers the cigarette liquid to the heating member. The first detecting device detects the degree of saturation of the liquid absorbing member, and feedbacks to the controller. The controller pre-determines the difference between the degree of saturation of the liquid absorbing member and the first threshold value. When the degree of saturation is greater than or equal to the first threshold value, the controller controls the liquid absorbing member to maintain the current degree of saturation or to control the degree of saturation of the liquid absorbing member to be reduced.
