Vapor generation system for testing smoking articles
The granted patent US12053029B1 describes a sophisticated system designed for the controlled delivery of aerosol emissions from smoking articles. Central to this system is an aerosol sensor positioned within a flowpath, complemented by a fluid pump that generates vapor flow at variable velocities. The system's operation is managed by a pump controller, which includes a processor and computer memory. The controller executes a series of operations that involve activating the fluid pump in a specific sequence: first at an overshoot velocity, then at a target velocity, followed by a reversal velocity, and finally at a second reversal velocity. This sequence allows for precise control over the flow dynamics, including the ability to create a pseudotrapezoidal flow pattern characterized by periods of increased velocity.
Additionally, the patent outlines methods for operating the fluid pump that ensure the fluid flows faster than the target velocity for a defined duration before returning to the target velocity for a longer duration. Notably, the system can be configured to have the reversal velocity exceed the target velocity, enhancing the versatility of the aerosol delivery process. The inclusion of a sensor-controller that communicates with the aerosol sensor further enables the generation of readings, facilitating real-time monitoring and adjustments. Overall, the patent presents a detailed framework for a system that optimizes aerosol delivery through controlled fluid dynamics, potentially improving the efficiency and effectiveness of aerosol-based products.
