The first step: when a fan (11) in the cavity of the first frame body (10) starts to work, air is sucked through an air inlet frame body (12) at the upper side, the sucked air needs to be filtered once through a filter cylinder (13), the filtered air is discharged downwards through an air outlet frame body (30), and when the air is discharged, the air is filtered for the second time through a fine filter screen (37);
and a second step of: when the filter cartridge (13) is used for filtering, the motor (15) drives the first cover plate (14) to drive the filter cartridge (13) to rotate, when the filter cartridge (13) works, the outer walls of the filter cartridges (13) positioned at two sides of the suction cover (19) are filtering areas which work, inhaled air is filtered on the outer walls of the filter cartridges (13) with floating ash or dirt in the air, and the working filtering areas of the filter cartridges (13) can be changed by driving the motor (15) to rotate at fixed time;
And a third step of: when the motor (15) drives the filter cylinder (13) to rotate, the rotating filter cylinder (13) is in friction contact with bristles (42) at the bottom of the suction cover (19), in the friction contact process, the bristles (42) can clean the outer wall of the filter cylinder (13) in a friction manner, floating ash or dirt can be scraped up, when the air pump (23) works, negative pressure is generated in the cavity of the air pump (23), negative pressure suction is carried out through the suction pipe (20) and the suction cover (19), and when the suction is carried out, the floating ash dirt just swept up on the outer wall of the filter cylinder (13) is sucked into the filter box (22) through the suction port (41), enters the filter box (22) and is blocked and filtered by the filter screen (24);
Fourth step: when the air discharged through the air outlet frame body (30) is subjected to secondary filtration through the fine filter screen (37), if the fine filter screen (37) works for a period of time, the upper surface of the fine filter screen possibly filters out a lot of fine dust and dirt; the working switch of the servo motor (36) is opened at regular time, the servo motor (36) drives the driving rod (40) to rotate, and when the driving rod (40) rotates again, the driving rod (40) rotates and winds the fine filter screen (37) to pull the fine filter screen (37), so that the filter surface of the fine filter screen (37) in the cavity of the air outlet frame body (30) is changed;
Fifth step: when the driving rod (40) in the second cylinder (34) is required to fully rotate and wind the fine filter screen (37), the second cylinder (34) is required to be opened through the second cover plate (35), all the fine filter screens (37) on the driving rod (40) are detached, the fine filter screen (37) is cleaned independently after being detached, the fine filter screen (37) is rotatably installed on the driven rod (39) after cleaning and drying are completed, the head end of the fine filter screen (37) is perforated (38) and then enters the second cylinder (34), and then the other end of the fine filter screen (37) is bound on the driving rod (40).
