FILTER REGENERATING APPARATUS

原文（中国語）

The present invention provides a filter regenerating apparatus comprising a dust load measurement unit, a control unit, and a vacuum cleaning device. The control unit activates the load measurement unit to measure the dust load on the filter and activates the vacuum cleaning device to vacuum clean the filter if the measured quantity of dust load exceeds a threshold value. The load measurement unit measures the quantity of dust load again after the filter is cleaned. If the dust load is still not lowered below the threshold value, then the system sends a filter replacement message to a user device. The efficiency of an air filter is best when it is neither new nor too dirty. By vacuum cleaning the filter in situ and by selecting an appropriate load threshold value, the filter can be used not only for a longer period but also with highest efficiency.
