Problems solved by technology

However, when used with an axial flow fan or a centrifugal fan, since the air passages of these two fans are relatively concentrated, it is difficult for the air to be purified to cover the entire surface of the ESP filter element, and the utilization efficiency of the filter element is low, which will reduce the filtration efficiency instead.

Abstract

The invention discloses an air purifier which comprises a shell and further comprises a cross-flow fan and a low-resistance filter element, wherein the shell comprises an air inlet and an air outlet;the low-resistance filter element is mounted at the air inlet; the cross-flow fan is arranged at the air outlet; and a pressure equalizing air duct is formed between the cross-flow fan and the low-resistance filter element so as to uniformly distribute negative pressure on the inner surface of the low-resistance filter element. According to the air purifier provided by the invention, the cross-flow fan and the low-resistance filter element are matched to be used, so that the contradiction between 'large air amount' and 'low noise' of the traditional air purifier can be solved. Therefore, the air purifier provided by the invention can achieve the technical advantages of large air amount and low noise. More importantly, the pressure equalizing air duct is formed inside the purifier, so thatthe negative pressure on the inner surface of the low-resistance filter element can be approximately uniformly distributed, the utilization efficiency of the low-resistance filter element can be greatly improved, and the filtering efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier. Background technique [0002] Most of the existing air purifiers use HEPA (High Efficiency Particle Air, high-efficiency air filter) filter element to filter the air. The removal efficiency of this filter element for particles above 0.3 microns can reach more than 99.7%. The most effective filter medium for pollutants. Its filtration principle is mainly to block particulate matter through screening, bridge plug, impact adhesion, electrostatic electret fiber electric field adsorption, etc. It has the characteristics of simple structure and high efficiency. [0003] However, the air resistance of the HEPA filter element is relatively large, and a fan with a higher power is required to pass the preset air volume, which consumes more energy and is prone to generate greater noise. At present, axial flow fans or centrifugal fans are mainly used in conjunction ...
