7. The use method of the air filtering mechanism for the portable air purifier as claimed in claim 6, characterized by comprising the following steps:

s1, when the air purifier is used, firstly, equipment is placed inside a shell of the air purifier through a bottom plate (3), then a servo motor (54), an ozone generator (14), a negative ion generator (15) and a UV ultraviolet lamp (16) on the equipment are electrically connected with a controller on the air purifier, and then the air purifier can be used;

s2, when the air purifier is used, the centrifugal wind wheel (55) is driven to rotate through the servo motor (54), so that outside air is sucked into the diversion trench (4) through the air inlet hole (53) and the through hole (51), then enters the space between the top plate (10) and the first fixing ring (131) through the third air inlet hole (1318), and is filtered through the first filter screen (132) and the second filter screen (133), and then is filtered through the first fixing ring

(131) The first air inlet hole (1316) at the top enters between the first fixing ring (131) and the second fixing ring (134), then passes through the third filter screen (135) and the fourth filter screen (136) to filter the air, then enters between the second fixing ring (134) and the third fixing ring (137) through the second air inlet hole (1317) at the top of the second fixing ring (134), then passes through the fifth filter screen (138) and the sixth filter screen (139) to filter the air, then enters between the third fixing ring (137) and the fourth fixing ring (1310) through the first air inlet hole (1316) at the top of the third fixing ring (137), then passes through the seventh filter screen (1311) and the eighth filter screen (1312) to filter the air, then enters between the fourth fixing ring (1310) and the fifth fixing ring (1313) through the second air inlet hole (1310 7) at the top of the fourth fixing ring (1310), then passes through the ninth filter screen (1314) and the tenth filter screen (1315) to filter, then enters into the inner barrel (1311) through the first air inlet hole (1311) at the top of the fifth fixing ring (1313), then passes through the UV sterilizer, and then passes through the UV sterilizer (16) and the UV sterilizer, and the UV sterilizer (17) and then passes through the UV sterilizer, and the UV sterilizer (21), finally, blowing out the waste water through an ash blocking net (12) so as to complete the whole purification process;

s3, when the filter mechanism (13) in the filter mechanism needs to be disassembled and cleaned, the push plate is used

(96) Drives the limit rod (94) to move, thereby driving the sliding plate (93) to move and extruding the return spring

(95) When the limiting rod (94) is completely separated from the inside of the limiting hole (8), the inner cylinder can be pulled upwards

(11) And the top plate (10) so as to finish the disassembly of the filtering mechanism (13), and then the filtering mechanism (13) can be cleaned;

s4, when the filtering mechanism (13) in the inner part needs to be installed, the inner barrel (11) is placed in the outer barrel (1) and then is placed downwards, so that the bottom of the fifth fixing ring (1313) is in contact with the top of the limiting ring (6), and meanwhile, the limiting rod (94) enters the limiting hole (8) under the action of the sliding plate (93) and the return spring (95), and the filtering mechanism (13) can be installed.
