Description

Technical Field

[0001] The utility model relates to the technical field of air filter cylinders, and more specifically to an air filter assembly with high sealing performance. Background Art

[0002] Air filter cartridges are mainly used in pneumatic machinery, internal combustion machinery and other fields. Their function is to provide clean air for these mechanical equipment to prevent them from inhaling air with impurities and particles during operation, which increases the probability of abrasion and damage. The working requirements of air filter cartridges are to be able to undertake high-efficiency air filtration work, not to increase too much resistance to air flow, and to be able to work continuously for a long time.

[0003] However, the filtering effect of the traditional air filter cylinder is poor, and the filter element cannot be replaced after the traditional filter cylinder has worked for a long time, thus failing to meet people's needs.

[0004] After searching, a Chinese patent with announcement number CN212701034U discloses an air filter assembly, which has a first filter compartment, a second filter compartment, a first fixed cylinder, a second fixed hole, a first filter element and a second filter element, achieving a multi-level filtering effect. In addition, a first water-injected sponge and a second water-injected sponge are provided, which can easily absorb dust in the air and achieve a high-efficiency filtering effect. At the same time, a sealing top cover and a sealing base are provided, which can facilitate disassembly, cleaning and replacement of the filter element.

[0005] However, when this structure is actually used, air directly enters the first fixed cylinder through the air inlet, and is adsorbed and filtered by the first water-injected sponge to filter dust in the air. However, since the wind direction of the air directly enters the interior of the second fixed cylinder through the third air vent, less air passes through the first filter element, which affects the filtering effect and makes it difficult to achieve multiple filtering effects.
