Problems solved by technology

In the related art, the primary filter is usually a layer of pleated filter. In actual use, some small dust particles can pass through the filter, resulting in poor filtering effect.
In addition, it is difficult to fix the pleated filter screen, and the fixing stability is low. In the process of cleaning the filter screen, it is easy to cause the filter screen to be disconnected from the surrounding metal frame, resulting in the scrapping of the filter screen.

Abstract

The invention discloses a filter assembly and an air treatment device. The filter assembly comprises a frame, a wrapping layer, filter cotton and a support framework. The frame is provided with a mounting window, the filter cotton is arranged in the mounting window, and the filter cotton comprises a first surface and a second surface which are opposite to each other. The wrapping layer wraps the first surface and the second surface, the support framework is arranged at the edge of the filter cotton to support the wrapping layer, the support framework is located between the first surface and the second surface, and the support framework is embedded in the frame. According to the filter assembly, in the process that airflow passes through the filter assembly, the airflow needs to sequentially flow through the wrapping layer at the first surface, the filter cotton and the wrapping layer at the second surface, the wrapping layer and the filter cotton can both filter the airflow, and therefore the filtration effect of the filter assembly can be improved; and the support framework is arranged, and therefore installation of the filter cotton and the wrapping layer is facilitated, the structural strength of the filter assembly can be improved, and the structural stability of the filter assembly can be improved.

Description

technical field [0001] The invention relates to the technical field of air ducts, in particular to a filter assembly and air treatment equipment. Background technique [0002] In the air treatment device, such as a total heat exchange fan, a primary filter is usually installed for preliminary filtering of the air to improve the cleanliness of the air. In the related art, the primary filter is usually a filter with a pleated structure. During actual use, some small dust particles can pass through the filter, resulting in poor filtering effect. In addition, it is difficult to fix the pleated filter screen, and the fixation stability is low. During the process of cleaning the filter screen, it is easy to cause the filter screen to be disconnected from the surrounding metal frame, resulting in the scrapping of the filter screen. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, ...
