Split type air purifier and filter module thereof

Abstract

The invention provides a split type air purifier and a filter module of the split type air purifier. A draught fan is arranged on an outdoor case, the filter module is arranged in an indoor case, the outdoor case is provided with a fresh air port, a return air port is independently formed in the position far away from the indoor case rather than being formed in the indoor case, positive pressure and large-range air circulation are formed, and indoor air flows to the outside only through gaps. The purifier further comprises an spherical air port, an adjustable grid plate type fresh air port, a module pressing-down mechanism and a touch screen, the filter module is a combined module capable of being freely combined, an early-effect filter module is made of bag type multi-layer non-woven fabrics, a formaldehyde removing, benzene removing, TVOC removing, degerming and deodorizing filter module is designed by adopting secondary cellular activated carbon, an efficient HEPA filter module is made of efficient H13 and H14 materials by piling multiple layer of Z-shaped folds, the split type air purifier is low in noise and good in dust removing, TVOC removing, degerming, benzene removing, smoke removing and deodorizing effect, the PM2.5 can reach the level of 0.1 micron, the oxygen content of air is high, and the effect of air circulation without dead angles in a room is achieved.

Description

technical field [0001] The invention relates to an air purifier and a filter module, in particular to a split-type air purifier with fresh air and return air circulation and a filter module thereof. Background technique [0002] At present, in terms of air purification effect, although there are many brands of purifiers in the market, they can be roughly divided into several categories from the perspective of their purification mechanism: physical adsorption type, electrostatic electronic dust removal type, ozone type, negative oxygen ion type, optical type, etc. catalytic technology, etc. It mainly attaches pollutants and suspended particles in the air to the filter screen through one or several layers of filter membranes, or captures indoor air particles with a wide range of particle sizes through electrostatic adsorption, so as to purify the air. The problems that purifiers exist are: 1. It is impossible to completely purify indoor air fundamentally. 2. The effect of du...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the shortcomings of current household air purifiers that have poor functions of dust removal, PM2. Its filter module has positive pressure dust removal effect, among which PM2.5 removal can reach 0.1 micron level, which is better than the existing 0.3 micron effect, and its benzene, formaldehyde, odor and smoke removal effects are all significantly clean Effect
