AI Technical Summary
Existing filtering masks suffer from pressure imbalances, humidity, and temperature issues due to non-coordinated exhalation valves and continuous extraction fans, leading to reduced breathing comfort and ineffective air exchange, with potential contamination from external airflows.
A ventilation device with a detachable design, featuring an inlet port, outlet port, exhalation valve, extraction fan, and sensors that activate the fan based on detected pressure, temperature, or humidity thresholds, and a command and control unit to regulate airflow dynamically.
Ensures optimal air exchange and comfort by adapting to respiratory rhythm and environmental conditions, preventing contamination while maintaining a large inner volume for breathing, even during strenuous activities.
