Intelligent constant control method and device for air filtration air volume

Abstract

The invention relates to the field of air filtration, in particular to an intelligent constant control method and device for the air filtration air volume. The intelligent constant control method and device can be used for intelligent constant control over the air filtration air volume. A large number of air purifiers and novel air filtration fans are used. But air filters of the air purifiers and air filters of the novel air filtration fans are gradually blocked by particulate matter along with using, so that the air volume is reduced, and accordingly experience brought to users are that the filtration efficiency of the air filters is poorer and poorer, and even a certain filtration effect can only be achieved a long time after starting. According to the intelligent constant control method and device, the air pressure difference between the front end and the rear end of each air filter is detected to control the work state of the fans, so that the air volume is made to be constant under the circumstance that filter screens are gradually blocked by dust, and the users are made to experience comfortably. The feeling that the air volume is smaller and smaller along with using is avoided, and the service life of the air filters is prolonged furthest. Meanwhile, when the air filters reach the design service life, replacement is pointed out. According to the intelligent constant control method and device, the filters are convenient to replace. The intelligent constant control method and device are suitable for the air purifiers and novel air filtration fans of any types, so that the application range is broadened.

Description

technical field [0001] The invention relates to the field of air filtration and can be used for intelligent constant control of the air volume of air filtration. Background technique [0002] In recent years, the quality of urban air has been declining, and air purifiers and fresh air purifiers have been widely used. Its air filter will gradually be blocked by particles as it is used, resulting in a decrease in air volume. The experience brought to users is that its purification efficiency is getting worse and worse, and even needs to be turned on for a long time to achieve a certain purification effect. And since the working state of the blower fan cannot be further intelligently controlled, the service life of the air filter cannot be extended. Contents of the invention [0003] The main purpose of the present invention is to address the above problems, to provide an intelligent and constant air filtration air volume control method and an air filtration air volume intel...

Problems solved by technology

Its air filter will gradually be blocked by particles as it is used, resulting in a decrease in air volume. The experience brought to users is that its purification efficiency is getting worse and worse, and even needs to be turned on for a long time to achieve a certain purification effect.

And because the working state of the fan cannot be further intelligently controlled, the service life of the air filter cannot be extended
