More Information
Summary:The utility provides a dust detection device, which is arranged between a gas filtering unit and a fan to detect the dust accumulation degree on the gas filtering unit. The dust detection device comprises two temperature sensors and a heater, wherein, one temperature sensor is utilized for sensing an environment temperature, and the other temperature sensor on the heater is utilized for sensing the temperature of the heater. The dust accumulation degree on the gas filtering unit is judged by comparison results between a temperature contrast delta T1 between the environment temperature and the heater temperature and an inbuilt standard temperature contrast delta T2.
