Description

Air filter

Technical Field

The utility model relates to the technical field of air filters, in particular to an air filter.

Background

The air filter element is a filter, also called air filter cartridge, air filter or style, mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms, the engine needs to absorb a large amount of air in the working process, if the air is not filtered, dust suspended in the air is absorbed into the cylinder, the abrasion of a piston group and the cylinder is accelerated, larger particles enter between the piston and the cylinder, and a serious cylinder pulling phenomenon is caused, which is particularly serious in a dry and sandy working environment, the air filter is arranged in front of a carburetor or an air inlet pipe, plays a role in filtering dust and sand grains in the air, and ensures that sufficient clean air enters the cylinder, but the traditional air filter has poor stability, and the machine is easy to shake off after installation, and has poor filtering effect, therefore, we propose an air cleaner.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an air filter which has the advantages of good stability and good filtering effect, and solves the problems that the traditional air filter is poor in stability, easy to fall off due to vibration of a machine after installation and poor in filtering effect.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an air filter, includes upper end cover and lower cover, the inner chamber threaded connection of upper end cover has the assembly screw, the spiral shell groove that uses with the cooperation of assembly screw is seted up to the inner chamber of upper end cover, the surface cover of assembly screw is equipped with the tight spring in top, be provided with filter paper between upper end cover and the lower cover, the surface of filter paper is provided with the non-woven fabrics, the mounting groove has been seted up to the inner chamber of lower cover.

Preferably, the assembly screw is of a plastic wrapping screw structure.

Preferably, the upper end cover and the lower cover are both of metal structures, and corrosion-resistant coatings are smeared on the surfaces of the upper end cover and the lower cover.

Preferably, the outer surface of the upper end cover is provided with an upper pressing strip, and the outer surface of the lower end cover is provided with a lower pressing strip.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the lower cover can be inserted on the mounting seat of the machine through the mounting groove, the assembly screw is screwed into the screw groove in the inner cavity of the upper end cover until penetrating through the screw groove and screwed in the groove of the mounting seat of the machine, so that the filter is stable, the assembly screw adopts a plastic screw wrapping mode, so that people can conveniently mount and dismount the assembly screw, the tightening spring increases the tightness between the filter and the machine, the filter paper is arranged in the upper end cover and the lower cover, the non-woven fabric is arranged outside the filter paper, the double-layer filtering improves the filtering precision of the filter, the service life can be effectively prolonged, the machine is protected, the lower pressing strip and the upper pressing strip can limit the non-woven fabric and the filter paper, the non-woven fabric and the filter paper are prevented from falling off, and the problems of poor stability, easy falling off of the machine after mounting and poor filtering effect of the traditional air filter are solved.
