Aerosol Device Suction Detection for Electronic Child-Lock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable aerosol generating devices lack effective child-lock mechanisms due to structural limitations, making them susceptible to accidental use by children.
Innovation Solution
A control method that integrates a sensor assembly to detect suction states and count suctions, activating a child-lock when thresholds are exceeded, and stopping atomization after prolonged use, ensuring safety without additional costs or complex components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a child-lock device is installed on the aerosol generating device, then the safety against accidental use by children is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The device uses its own existing sensor assembly and control circuit to automatically detect suction actions and implement child-lock functionality without requiring external additional components. The system serves itself by utilizing already-present hardware resources to achieve the safety function.
Solution Approach 2:
The patent replaces mechanical child-lock devices with an electronic control system that uses sensor detection and software logic to prevent accidental use. This substitution eliminates the need for physical locking mechanisms while maintaining safety functionality.
2Reliability
If a child-lock device is installed on the aerosol generating device, then the safety against accidental use by children is improved, but the manufacturing cost increases
Solution Approach 1:
The device uses its own existing sensor assembly and control circuit to automatically detect suction actions and implement child-lock functionality without requiring external additional components. The system serves itself by utilizing already-present hardware resources to achieve the safety function.
Solution Approach 2:
The sensor assembly serves multiple functions: it detects user suction actions for normal operation and simultaneously monitors for child-lock conditions. This multi-functionality eliminates the need for separate dedicated child-lock sensors, reducing component count and manufacturing cost.
3Ease of operation
If the aerosol generating device is kept in standby mode to sense user suction action, then the responsiveness to user needs is improved, but the energy consumption increases
Solution Approach 1:
The device periodically checks suction status rather than maintaining continuous standby monitoring. The control circuit detects suction actions at appropriate intervals, balancing responsiveness with energy conservation by activating full monitoring only when needed.

AI summary
A control method for an aerosol-generating device, including: detecting whether an aerosol-generating device is in a suction state (S110); detecting a child-lock state of the aerosol generating device (S120); determining whether the number of suctions of the aerosol generating device within a first preset time period is greater than a first threshold (S130); enabling the aerosol generating device to be in a child-lock closed state (S140); determining whether the single atomization time of the aerosol generating device is greater than a second time threshold (S150); and the aerosol generating device stopping atomization (S160). By integrating a child-lock on an airflow sensor of the aerosol generating device, the aerosol generating device can prevent children from accidental suction; moreover, without increasing costs or adding complex structural members, the original technical design is maintained, and a child-lock function is added, thereby preventing children from accidental use, and greatly reducing the manufacturing cost.
