Atomizer Power Limiting to Prevent E-Cigarette Dry Burning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarette atomizers are prone to dry burning when operating at high power, which can damage the heating component and reduce the smoking experience.
Innovation Solution
A control method and device that detect the maximum output power of the atomizer and adjust it to prevent dry burning by limiting the output power to the maximum safe level, displaying reminders to users, and adjusting based on resistance value, liquid level, and temperature data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the atomizer outputs at high power to generate large smoke, then the user demand for large smoke is met, but the atomizer is prone to dry burning
Solution Approach 1:
The system dynamically adjusts the output power parameter of the atomizer based on detected resistance values. When the resistance value indicates a risk of dry burning, the system changes the power parameter from high to a safe level, preventing damage while still providing acceptable smoke generation.
Solution Approach 2:
The system continuously monitors the resistance value of the atomizer and uses this feedback to adjust the output power. When the resistance value exceeds a threshold indicating dry burning risk, the system responds by reducing power, creating a closed-loop control that prevents damage while maintaining performance.
2Reliability
If the maximum output power is limited to prevent dry burning, then the atomizer safety is improved, but the smoke generation capability is reduced
Solution Approach 1:
The system dynamically adjusts the maximum output power limit based on real-time resistance value detection rather than using a fixed limit. This allows the system to maintain high power when safe (generating large smoke) and reduce power only when necessary (preventing dry burning), resolving the contradiction between safety and performance.
Solution Approach 2:
The system performs preliminary detection of resistance values before allowing high power output. By checking the resistance value in advance and comparing it against thresholds, the system prevents dry burning before it occurs while allowing maximum power generation when conditions are safe.
3Reliability
If the system detects and adjusts power in real-time, then the atomizer protection is improved, but the device complexity increases
Solution Approach 1:
The system uses the existing resistance value detection capability (already present in the electronic cigarette) to protect the atomizer without adding separate sensors or complex monitoring systems. The existing electrical parameters are repurposed for protection, minimizing additional complexity while achieving reliable atomizer protection.

AI summary
A control method and device, and an electronic cigarette. The method includes: obtaining the maximum output power during the secure output of an atomizer connected to a body; detecting whether the currently-set target power of the atomizer is higher than the maximum output power; and if the target power is higher than the maximum output power, executing a preset operation, the preset operation including at least one of controlling, the atomizer to output at power lower than or equal to the maximum output power and displaying a first reminder message, according to a cigarette lighting signal. The method resolves the problem that dry burning would easily occur in an atomizer, and has the function of protecting the atomizer and preventing the shortening of the life of a heating component caused by the burning of the heating component due to high power output of the atomizer.
