Air Purifier Operation Mode Control Based on Coverage-to-Area Ratio

The patent applies dynamics by making the fan blade speed adjustable rather than fixed. The control unit dynamically adjusts the fan blade rotational speed based on real-time air quality detection data, allowing the system to achieve high purification output when needed while maintaining compact size by operating at lower speeds during normal conditions. This resolves the contradiction by making the purification capability dynamic rather than requiring a permanently large fan blade.

The patent changes the operational parameters of the fan blade by adjusting its rotational speed according to air quality levels. Instead of using a large-diameter fan blade to ensure sufficient purification capacity, the system maintains a compact fan blade and compensates by varying its speed parameter. When air quality deteriorates, the fan blade speed increases to maximize purification output, thereby achieving high productivity without increasing the physical size of the air purifier.

The system dynamically adjusts fan blade rotational speed based on real-time air quality conditions. During normal air quality, the fan operates at low speed consuming minimal power. When air quality deteriorates and high purification output is needed, the control unit increases the fan blade speed to maximize purification efficiency. This dynamic adjustment resolves the contradiction by ensuring high power consumption only occurs when high purification output is actually required.

The patent changes the rotational speed parameter of the fan blade according to air quality levels detected by the sensor. Instead of maintaining high rotational speed continuously (which would consume excessive power), the system adjusts the speed parameter dynamically. When air quality is good, low speed suffices; when air quality deteriorates, the speed parameter is increased to achieve high purification output. This parameter-based control resolves the contradiction between productivity and energy consumption.

The patent makes the air purifier universal by enabling it to adapt to different air quality conditions and coverage requirements through dynamic speed adjustment. A single air purifier unit can effectively cover varying areas by adjusting its fan blade speed - operating at high speed for large area coverage when air quality is poor, and at low speed for smaller areas during normal conditions. This multi-functionality resolves the contradiction by allowing one unit to perform the work of multiple units, thereby reducing overall cost while maintaining adequate coverage.

The system uses parameter changes in fan blade rotational speed to extend the effective coverage area of a single air purifier. By adjusting the speed parameter, the same device can serve different coverage requirements - high speed for large area purification when needed, low speed for smaller areas. This eliminates the need to deploy multiple purifiers for varying coverage needs, thereby reducing the quantity of devices required and lowering overall cost while maintaining improved coverage capability.
