Airflow-Locked Atomizer Port for Unauthorized Aerosol Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices lack effective mechanisms to prevent unintended aerosol generation and unauthorized access, particularly for users who are not inhaling, such as children, and do not efficiently control power delivery to the heating element based on airflow sensing.
Innovation Solution
An electronic atomization device with a movable occluding element and locking mechanism that blocks airflow communication until unlocked, combined with an airflow sensor to control power to the heating element, ensuring aerosol generation only occurs during inhalation and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable occluding element is added to block the communication port, then unauthorized access and unintended aerosol generation are prevented, but device complexity increases
Solution Approach 1:
The occluding element is positioned to preemptively block the communication port before any unauthorized access or unintended aerosol generation can occur. This preliminary blocking action ensures that the device remains in a secure default state, and only allows airflow when properly activated by the locking mechanism during legitimate use.
Solution Approach 2:
The occluding element acts as an intermediary component between the communication port and the external environment. It mediates airflow by selectively blocking or permitting passage based on the state of the locking mechanism, thereby preventing direct unauthorized access while maintaining controlled communication during legitimate operation.
2Use of energy by moving object
If an airflow sensor is used to control power delivery, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The airflow sensor provides real-time feedback about airflow conditions to the control circuit. This feedback loop enables the control circuit to dynamically adjust power delivery to the heating element based on actual airflow detection, ensuring energy is only consumed when needed for legitimate aerosol generation during inhalation events.
Solution Approach 2:
The airflow sensor enables the device to self-regulate its power consumption by automatically detecting airflow conditions and controlling power delivery accordingly. The system serves itself by using environmental airflow information to make intelligent power management decisions without requiring external control inputs.
3Reliability
If the locking mechanism is always engaged, then unauthorized access is prevented, but ease of operation deteriorates
Solution Approach 1:
The locking mechanism transitions from a static always-engaged state to a dynamic system that can switch between locked and unlocked states. This dynamic capability allows the device to maintain security when needed while enabling convenient operation during legitimate use, adapting its security level based on operational context.
Solution Approach 2:
The locking mechanism operates periodically, alternating between locked and unlocked states based on legitimate user activation. During normal operation, it periodically unlocks to allow airflow and aerosol generation, then re-locks to prevent unauthorized access, creating a rhythmic pattern of security and accessibility that balances both requirements.

AI summary
Disclosed in the present application is an electronic atomization device. The electronic atomization device comprises: a liquid storage cavity; a heating element; a battery cell; an airflow channel; an airflow sensor comprising a first side and a second side, wherein the first side is configured to be in airflow communication with the airflow channel, and the second side is configured to be in communication with the outside atmosphere; a communication port for providing a channel for communicating the second side with the outside atmosphere; a movable blocking element, by means of which the communication port is selectively open or closed; a locking mechanism, wherein when the blocking element is located at a closed position, the locking mechanism is in a locking state so as to prevent the blocking element from being moved to an open position, and the locking mechanism in an unlocking state allows the blocking element to be moved to the open position; and a circuit, which controls the battery cell to provide electric power according to a sensing result of the airflow sensor. In the electronic atomization device, the blocking element is locked at the closed position by means of the locking mechanism, thereby preventing the blocking element, before same is unlocked, from being moved from the closed position to the open position so as to obtain aerosol.
