Air cleaner

Abstract

The invention provides an air filter, comprising a shell and a filter core; the shell is provided with an air inlet and an air outlet; the filter core is laminated between two filter core frameworks; the periphery of the filter core is arranged in the installation trough of the internal chamber wall of the shell; the internal chamber of the shell is divided into two parts by the filter core; wherein, one part is connected with the air inlet; and the other part is connected with the air outlet; two filter core frameworks are connected with each other at one end so as to form a whole in a U-shape; a sealing bar is arranged between the connecting end of the two filter core frameworks and the installation trough. The filter core and the filter core framework of the invention is not connected with each other by screws, the assembly of the filter core is more convenient; furthermore, the sealing performance of the periphery of the filter core and the shell internal wall is more reliable.

Description

technical field [0001] The invention relates to an air filter. Background technique [0002] The filtering air filter is mainly composed of a shell and a filter element. The filter element divides the inner cavity of the shell into two parts, one part is connected with the air inlet, and the other part is connected with the air outlet. For flat block filter elements, the filter element is usually sandwiched between two independent filter element skeletons on the left and right, connected into a whole with screws and then snapped into the installation groove of the inner cavity wall, or the left and right sides are connected by a long screw rod. The two filter element skeletons and the filter element are supported in the inner cavity as a whole. This structure has the following defects: [0003] 1. Since screws or screws are used for installation and connection, the assembly is cumbersome, and the connecting screws or screws have to pass through the filter element, which des...

AI Technical Summary

Problems solved by technology

[0003] 1. Since screws or screws are used for installation and connection, the assembly is cumbersome, and the connecting screws or screws have to pass through the filter element, which destroys the integrity of the filter element;

[0004] 2. There is a problem of poor airtightness between the periphery of the filter element and the inner wall of the housing, which may easily cause insufficient air filtration, and the air intake resistance cannot be guaranteed as it should be
