Filter element of air purifier

Abstract

The invention relates to the technical field of air purification, in particular to a filter element of an air purifier. The filter element comprises a collecting box, a filtering unit and an ash removal unit, wherein the filtering unit is installed at the upper end of the collecting box, and the ash removal unit is arranged on the filtering unit. An existing air purifier filter element has the following problems that according to an existing air purifier filter element, only a dust removal layer can be replaced; if the dust removal layer is not replaced in time, the dust removal layer can be blocked, then the filter element is blocked, and the air purification effect is influenced; and the filter element cannot achieve multi-stage filtration, the filtration degree is low, and thus, the air purification effect is influenced. According to the filter element of the air purifier, dust is effectively prevented from blocking the air purifier, the air purification effect can be enhanced, and the collected dust can be conveniently removed in a unified mode; and according to the invention, the filtering strength of dust and foreign matters in air can be improved, so that the filtering effect of the air purifier on the air can be enhanced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier filter element. Background technique [0002] Air purification technologies commonly used in air purifiers include: adsorption technology, negative and positive ion technology, and electrostatic dust collection technology; among them, the air purifier using adsorption technology mainly purifies the air through its internal filter element, and the filter element is mostly composed of a dust removal layer. , HEPA corrugated layer, activated carbon layer and odor filter. Since the filter element absorbs dust and foreign matter in the air, its own purification effect will be weakened. Therefore, it is necessary to regularly clean the filter element and replace it when necessary. Ensure its ability to purify the air. [0003] The existing air purifier filter elements have the following problems: 1. At present, most of the air purifier filter elements on the m...

AI Technical Summary

Problems solved by technology

[0003] The existing air purifier filter elements have the following problems: 1. At present, most of the air purifier filter elements on the market first filter the dust and foreign matter in the air through the dust removal layer, and this type of filter element cannot effectively remove dust and foreign matter. For collection, only the dust removal layer can be replaced, so it is easy to cause dust and foreign matter to scatter in the air, thus affecting the air quality. The foreign matter adhered to the air will affect the quality of the purified air, thereby affecting human health

[0004] 2. Since this type of filter element cannot achieve multi-stage filtration when filtering air, the degree of filtration of this type of filter element is low, and it cannot effectively filter dust and foreign objects in the air, thus affecting the air purification effect
