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, leading to reduced service life and compromised smoking experience.
Innovation Solution
A control method that determines the maximum output power of the atomizer and adjusts the target power to prevent dry burning by controlling the atomizer to output at or below this maximum power, accompanied by a reminder message to users when high power settings are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the atomizer outputs large power to generate large smoke, then the smoke generation is improved, but the atomizer is prone to dry burning
Solution Approach 1:
The patent implements a feedback control mechanism where the control unit continuously monitors the output power of the atomizer and compares it against a pre-stored maximum power value. When the detected power exceeds the maximum threshold, the system automatically adjusts the power output to prevent dry burning, thus resolving the contradiction between high smoke generation and atomizer reliability
Solution Approach 2:
The patent changes the power output parameter dynamically based on operational conditions. By storing maximum power values corresponding to different working conditions and switching between them, the system maintains optimal smoke generation while preventing the atomizer from operating beyond safe power limits that would cause dry burning
2Quantity of substance
If the atomizer outputs large power, then the smoking experience is improved, but the service life of the atomizer is reduced
Solution Approach 1:
The patent applies preliminary action by pre-storing maximum power values corresponding to different working conditions in the control unit before operation begins. This pre-prepared data allows the system to immediately adjust power output to safe levels when conditions change, preventing cumulative damage that would reduce atomizer service life while still allowing high smoke output during appropriate conditions
Solution Approach 2:
The continuous feedback mechanism monitors actual power output and compares it with pre-stored maximum values, automatically adjusting the power delivery to extend atomizer life while maintaining satisfactory smoke output during normal operation

AI summary
A control method and device, and an electronic cigarette. The method comprises: obtaining the maximum output power during the secure output of an atomizer connected to a body (110); detecting whether the currently-set target power of the atomizer is higher than the maximum output power (120); and if the target power is higher than the maximum output power, executing a preset operation, the preset operation comprising at least one of controlling, according to a cigarette lighting signal, the atomizer to output at power lower than or equal to the maximum output power and displaying a first reminder message (130). 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.
