Electronic Cigarette Control Method for E-Liquid Level Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes cannot accurately calculate the remaining e-liquid and fail to remind users when it is almost exhausted, leading to potential scorched smells due to continued use without sufficient e-liquid.
Innovation Solution
An electronic cigarette control method that stores preset values for e-liquid amounts and available smoking time, prompting users when the e-liquid is low and controlling the atomization circuit to turn off when it is almost exhausted, ensuring timely e-liquid replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic cigarette continues to heat and atomize when e-liquid is insufficient, then the atomization function is maintained, but scorched smell is generated and user experience deteriorates
Solution Approach 1:
The system performs preliminary detection of e-liquid levels and issues warnings before the e-liquid is completely exhausted. By detecting the remaining e-liquid amount in advance and notifying the user, the system prevents the harmful condition of scorched smell from occurring in the first place
Solution Approach 2:
The system continuously monitors e-liquid levels and provides feedback to the user through display or audio warnings. This feedback mechanism allows the user to understand the e-liquid status and take appropriate action (replacing the cartridge) before scorched smell is generated
2Device complexity
If no e-liquid amount detection is implemented, then the device structure remains simple, but the user cannot be reminded of remaining e-liquid
Solution Approach 1:
The electronic cigarette system automatically performs e-liquid level detection and self-diagnosis without requiring external intervention. The detection circuit and control unit work autonomously to monitor e-liquid levels and provide warnings, making the system self-aware of its operational status

AI summary
The present invention relates to an electronic cigarette and a method for controlling the electronic cigarette. The method for controlling electronic cigarette comprises: reading the available smoking time when an atomization circuit of the electronic cigarette is in a turn-off state and the electronic cigarette detects a user's smoking action; determining whether or not the available smoking time is equal to or less than the first preset value to obtain a first determination result; when the first determination result is YES, outputting a prompt message to remind the user that e-liquid is almost to be exhausted, and outputting the available smoking time and/or available smoking times of the electronic cigarette; determining whether the available smoking time is greater than the second preset value to obtain a second determination result; controlling the atomization circuit to stay in the turn-off state when the second determination result is NO.
