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 as an air filter cartridge, an air filter, a style and the like, and is mainly used for filtering air in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms, a large amount of air is sucked in an engine in the working process, if the air is not filtered, dust suspended in the air is sucked into a cylinder, the abrasion of a piston group and the cylinder is accelerated, larger particles enter between a 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 of filtering dust and sand grains in the air, ensures that sufficient and clean air enters the cylinder, the existing air filter has poor internal sealing performance, so that the air filtering quality is reduced, and does not have a function of uniformly arranging the filter paper, reducing the filtering effect of the filter paper itself.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an air filter which has the advantages of improving the sealing performance and uniformly distributing filter paper, and solves the problems that the air filter quality is reduced due to poor internal sealing performance of the conventional air filter, and the filter effect of the filter paper is reduced due to the fact that the filter does not have the function of uniformly distributing the filter paper.

In order to achieve the purpose, the utility model provides the following technical scheme: the air filter comprises an upper end cover, wherein a lower end cover is arranged on the left side of the upper end cover, filter paper is arranged between the upper end cover and the lower end cover, an outer net is arranged at the top of the filter paper, a sponge is arranged at the top of the outer net, and a composite gasket is arranged on the left side of the lower end cover.

Preferably, the sponge and the outer net are both located between the upper end cap and the lower end cap.

Preferably, two symmetrical crescent grooves are pressed on the right side of the upper end cover.

Preferably, the left side of lower end cover is provided with the extension piece, and the equal fixed mounting in both ends of extension piece has the strengthening rib.

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

1. according to the utility model, through the matching of the upper end cover, the sponge, the outer net, the lower end cover, the composite gasket, the crescent groove and the reinforcing ribs, the purposes of improving the sealing property in the device and ensuring that the filter paper can be uniformly distributed are realized, the damage to an engine caused by the entry of moist large-particle impurities into the device is prevented, and the problems that the air filtering quality is reduced due to poor sealing property in the conventional air filter, the filter paper is not uniformly distributed, and the filtering effect of the filter paper is reduced are solved.

2. The filter paper fixing device has the advantages that the upper end cover and the lower end cover are arranged to play a role in fixing and limiting the sponge, the outer net and the filter paper, so that the sponge, the outer net and the filter paper are prevented from deviating and affecting the normal use of the device, the crescent grooves are arranged to uniformly arrange the filter paper, the use reliability of the filter paper is improved, the filtering effect of the filter paper is ensured, the device is convenient to mount by arranging the reinforcing ribs, the stability of the device during mounting is improved, and the device is prevented from deviating and deforming.
