Electronic Cigarette Power Control for Stable Aerosol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette control methods result in unstable smoke production and mouth burning due to power fluctuations and cold start conditions, with full-power output causing excessive heat and constant-power output leading to insufficient aerosol at initial use.
Innovation Solution
A method that adjusts power levels based on time intervals and e-liquid remaining amounts, with power settings inversely proportional to environment temperature, ensuring stable smoke production and preventing prolonged high-power usage that causes mouth burning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If full-power output is used to heat, then heating efficiency is improved, but smoke amount becomes unstable and mouth burning occurs
Solution Approach 1:
The patent implements dynamic power adjustment by dividing operation into different stages (cold start stage, normal stage, low e-liquid stage) with different power levels. The controller dynamically switches between first power, second power, and third power based on operational conditions, resolving the contradiction between maintaining high heating efficiency and ensuring stable smoke output.
Solution Approach 2:
The patent applies preliminary action by implementing a cold start stage with second power (lower than first power) before transitioning to normal operation. This preliminary lower-power operation allows the heating module to reach optimal temperature gradually, preventing smoke instability and mouth burning while ensuring reliable operation from the beginning.
2Object-affected harmful factors
If constant-power output is used to heat, then mouth burning is avoided, but smoke amount is insufficient during cold start
Solution Approach 1:
The patent uses dynamic power adjustment across different operation stages. During cold start, second power is applied to prevent mouth burning, while during normal operation, first power (higher than second power) is used to generate sufficient aerosol. This dynamic approach resolves the contradiction between avoiding harmful effects and ensuring adequate substance output.
Solution Approach 2:
The patent segments the operation into distinct stages (cold start, normal, low e-liquid) with different power levels. By segmenting the constant-power operation into stage-specific power levels, the system can provide higher power when needed for sufficient aerosol generation while maintaining lower power when safety is the priority, thus resolving the contradiction.
3Quantity of substance
If high power is used to generate aerosol, then smoke amount is sufficient, but device temperature increases causing mouth burning
Solution Approach 1:
The patent implements dynamic power control where the controller adjusts power levels based on operational stage and e-liquid conditions. By switching between first power, second power, and third power at appropriate times, the system generates sufficient aerosol during normal operation while preventing excessive temperature accumulation, thus resolving the contradiction between adequate aerosol output and temperature control.
Solution Approach 2:
The patent applies periodic action through timed power adjustments and duration limits. The controller sets maximum duration for first power operation and automatically transitions to lower power modes, creating a periodic cycle of high and low power operation. This ensures sufficient aerosol generation during high-power periods while allowing cooling during low-power periods, resolving the temperature-aerosol contradiction.
4Reliability
If power is adjusted based on time interval and e-liquid remaining amount, then smoke stability is improved, but control complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining power levels (first, second, third power) and duration parameters for different operational stages. The controller simply needs to determine the current stage and select the corresponding pre-configured power level, rather than performing complex real-time calculations. This approach improves smoke stability through systematic control while minimizing control logic complexity.
Solution Approach 2:
The patent implements feedback mechanisms by monitoring e-liquid remaining amount and operational stage, then automatically adjusting power levels accordingly. The controller receives feedback about device state and responds by selecting appropriate pre-defined power modes, achieving stable smoke output through simple conditional logic rather than complex continuous control algorithms.

AI summary
The present disclosure provides a method for controlling an electronic cigarette and an electronic cigarette. The method includes: acquiring a work start signal of the electronic cigarette (S1); acquiring a time interval between starting work this time and stopping work last time (S2); when the time interval is greater than a first preset time interval, controlling the electronic cigarette to work at a first power, and when a duration of the first power is greater than a first preset duration, turning off the electronic cigarette; when the time interval is greater than a second preset time interval but less than or equal to the first preset time interval, controlling the electronic cigarette to work at a second power, and when a duration of the second power is greater than a second preset duration, turning off the electronic cigarette; wherein, the first power is greater than the second power (S3). The present disclosure can stabilize the amount of smoke when the electronic cigarette is working and prevents the user from mouth burning when smoking.
