Air Purifier Intelligent Sensor Feedback for Real-Time Quality Control

The patent implements feedback control by using sensors to continuously monitor air quality parameters (particulate matter, VOCs, temperature, humidity) and automatically adjusting fan speed and purification operations based on real-time readings. The controller compares sensor data against predetermined thresholds and modifies system operation accordingly, creating a closed-loop control system that maintains optimal air purification without manual intervention.

The air purifier system performs self-diagnosis and self-adjustment through integrated sensors and controllers that automatically detect air quality conditions, monitor filter status, and adjust operational parameters without user input. The system serves itself by autonomously optimizing purification performance and detecting component malfunctions, reducing the need for external monitoring and manual maintenance scheduling.

The patent employs dynamic operation by continuously varying fan speed and purification intensity based on real-time air quality sensor readings. Instead of operating at fixed speeds, the system dynamically adjusts its performance level to match actual contamination conditions, maximizing air purification efficiency when pollution is high and reducing operation when air quality is good, thereby optimizing productivity throughout the operating cycle.

The system changes operational parameters (fan speed, motor power, airflow rate) in response to sensor feedback about air quality conditions. The controller modifies these parameters dynamically based on measured concentrations of particulates, VOCs, and environmental conditions, allowing the air purifier to adapt its productivity to actual needs rather than operating at constant suboptimal levels.

The patent incorporates feedback mechanisms where sensors continuously monitor not only air quality but also system operational parameters. The controller receives feedback on filter status, motor performance, and airflow conditions, comparing these against expected ranges to detect deviations indicating component malfunctions or degradation, enabling early warning and maintenance scheduling before performance deteriorates.

The patent replaces manual inspection and mechanical monitoring with electronic sensors and digital control systems. Instead of physically checking filters and components, the system uses electronic sensors to detect air quality changes, flow rate variations, and power consumption patterns that indicate component issues, substituting mechanical monitoring with electronic detection and analysis.
