Self anti-deformation flushable air cleaner

Abstract

The invention relates to a self anti-deformation flushable air cleaner, which comprises a cylindrical shell, a pleated filter core, a mainstream wind inlet, a mainstream wind outlet and a purified wind outlet. The pleated filter core is provided in the cylindrical shell, two ends of the pleated filter core are fixedly connected with the cylindrical shell, the purified wind outlet is communicated with the pleated filter core. The invention is characterized in that the pleated filter core is composed of a group of filter discs by staking up, the adjacent filter discs are connected by an interlace mode according to an inner edge connection, an outer edge connection and the inner edge connection, an outer ring formed by the out edge connection is provided with a circular rigid outer ring; or the outer ring is provided with a circular rigid outer ring, an inner ring formed by the inner edge connection is provided with a rigid inner ring. The anti-deformation performance is realized by completely depending on the filter material itself and the rigid outer ring, so that the self anti-deformation flushable air cleaner is capable of simplifying the structure, reducing the processing difficulty, raising the self-cleaning effect and prolonging the usage life of the filter core.

Description

Technical field [0001] The invention relates to a self-deformation-resistant and washable air filter, belonging to the field of air filters. Background technique [0002] One of the requirements for air filters is low resistance and long life. If the filter element of the air cleaner is blocked by dust, the resistance of the filter element will increase until it fails. [0003] In order to increase the filtering area of ​​the existing air cleaner, the filter material is often folded into folds, and the two ends of the folds are glued to the opposite baffles, and a semi-closed space is formed between the adjacent folds and the baffles. [0004] There are three shortcomings in this structure. The first is that the circumference of the pleated outer ring of the existing cylindrical filter element is larger than that of the inner ring, which will inevitably cause the density of the inner and outer rings to be different. The smaller the inner ring, the smaller the inner ring relative to ...

Problems solved by technology

At the same time, use the filter element itself and the rigid outer ring (or use the rigid inner ring at the same time) to constrain each part of the filter element pleats, so that the filter element pleats will not be deformed and close together, and there is no problem that the existing rectangular filter element increases the folding width. And form an airflow channel for flushing
