Problems solved by technology

There are following defects in this method: 1, the air quality in various places is not the same, and this method can not be distinguished, and in the place of good air quality and the place of poor air quality, the time of reminding to change filter screen is the same; 2, this method cannot Different gears of different machines, the gears of the machine are different, the air volume is different, and the speed of life loss is actually different; 3. This method cannot distinguish filters of different sizes. The size of the filters is different. life span is different
This method has high requirements on the sensor and is also not suitable for household air purifiers.

Abstract

The invention discloses a method for judging the life of an air purifier filter screen, wherein the method comprises the following steps: determining the dust containing capacity M of the selected purifier filter screen through tests, determining the initial filtration efficiency eta0 of the filter screen and the filtration efficiency eta1 of the filter screen when the service life is ended, determining the purifier running air volume Q, assuming an actual working time, and reminding a user to replace or clean the filter screen. In the premise without addition of extra cost, according to easily acquired data including the purifier running air volume Q, the filter screen filtration efficiency, the working time and the like, and through a reasonable operation mode, the user can be accurately reminded to replace the filter screen, so as to prevent the user from untimely replacing the filter screen so as to prevent waste, or prevent the user from replacing the filter screen too late so as to prevent from causing bad effect or even causing secondary pollution; even the filter screen works in different seasons, different regions and different pollutant concentrations, the replacement time of the filter screen also can be reasonably prompted to ensure the reasonable use of the filter screen and not to cause waste.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a method for judging the service life of an air purifier filter screen. Background technique [0002] The filter of the air purifier needs to be cleaned or replaced after being used for a period of time. The current method of judging the life of the filter of the household air purifier on the market is generally to set the total use time of the filter. When the cumulative operating time of the air purifier reaches The user is reminded to replace the filter after the set usage time of the filter. There are following defects in this method: 1, the air quality in various places is not the same, and this method can not be distinguished, and in the place of good air quality and the place of poor air quality, the time of reminding to change filter screen is the same; 2, this method cannot Different gears of different machines, the gears of the machine are different, the air volume is d...
