Description

A kind of car air filtering core

Technical field

The utility model relates to technical field of automobile, particularly relates to a kind of car air filtering core.

Background technology

With social development, automobile has become the necessity of a lot of people life.Wherein, the engine of automobile is in work When need to absorb substantial amounts of air and start engine to cooking combustion adjuvant with gasoline, and air contains substantial amounts of dust, once These dusts enter engine, meeting heavy wear engine, reduce the life-span of engine, and air filter can well reduce Enter the dust of engine.But existing air filtering core still has very big problem, filter core longevity of service rear surface can be amassed Tire out substantial amounts of dust and have a strong impact on ventilation smoothness, increase the stress of filter core simultaneously, cause filter core to bend, even deficiency of air Engine is caused to work.And air filtering core is operationally, absorb substantial amounts of air, wherein have a lot of steam to be accumulated in On filter paper, ventilation is caused to have some setbacks.

Utility model content

The utility model solves the technical problem that the defect being to overcome prior art, provides a kind of car air filtering core. Described a kind of car air filtering core has water absorbing capacity and the feature preventing filter paper from being pulled, and improves the service life of filter core.

For achieving the above object, the following technical scheme of the utility model offer: a kind of car air filtering core, including outer filtration Cylinder and inner filtration cylinder, the two ends of described outer cartridge filter are respectively connected with mounting ring, and the outside of described mounting ring is provided with sealing ring, described The two ends of inner filtration cylinder are plugged in the mounting ring that outer cartridge filter two ends connect respectively, and the interior of outer cartridge filter be located at by described inner filtration cylinder Portion, described outer cartridge filter includes urceolus wire netting, and described urceolus wire netting has and is provided with nothing between two-layer, and two-layer urceolus wire netting Spinning cloth and filtering cotton, the outside filtering cotton is located at by described non-woven fabrics, and the middle part of described inner filtration cylinder is connected with flexible Pipe, described inner filtration cylinder includes inner core wire netting, and described inner core wire netting has and was provided with between two-layer, and two-layer inner core wire netting Filter paper.

Preferably, described outer cartridge filter is Pear-Shaped.

Preferably, the mesh of described urceolus wire netting is more than the mesh of inner core wire netting.

Technique effect of the present utility model and advantage: outside this retractility that can pass through telescoping tube and Pear-Shaped, cartridge filter is micro- Weak elasticity can make easy for installation, and can strengthen filer element strength, the retractility of telescoping tube by the outer cartridge structure of Pear-Shaped The good filter paper preventing two ends is pulled, and the filtration cotton simultaneously arranging can absorb the moisture in air, decreases The burden of filter paper, improves the service life of filter core.
