Indoor air purifier

Abstract

The invention relates to an indoor air purifier and belongs to the technical field of air purifiers. The air purifier is connected with a power source; a fan rotates, air is delivered outwards throughair outlets, and the negative pressure is generated inside a box body; air is delivered into the box body through air inlets; the air passes through a barrel-shaped primary filter screen and a secondary filter screen in the first place, and large solid impurities in the air are filtered out; the air obtained after filtration enters a toxicity filtering layer; by means of the toxicity filtering layer, harmful gas in the air react with compounds in the toxicity filtering layer and is converted into nontoxic substances, and thus, the harmful gas in the air is filtered out; the air obtained afterfiltration enters a HEPA filter screen, and by means of the HEPA filter screen, fine particulate matter in the air is filtered out; the air obtained after filtration is heated through an electric heating layer, so that air is formed; and the air is blown through a fan to pass through air refresher and discharged into a room through the air outlets, and thus purification of the indoor air is completed. By means of the indoor air purifier, the indoor air can be effectively purified; and the effects that peculiar smell is removed, and the toxic gas, dust and suspended particulate matter are filtered out can be achieved.

Description

technical field [0001] The invention relates to an indoor air purifier, which belongs to the technical field of air purifiers. Background technique [0002] Nowadays, many living rooms and office places adopt closed decoration, and a large number of decorative materials used in modern decoration will more or less cause indoor air pollution. For example, formaldehyde is a common indoor air pollutant brought by decoration. The formaldehyde content produced by newly renovated houses can exceed the standard by more than 6 times, and some may exceed the standard by more than 40 times. In addition, admixtures containing a large amount of ammonia substances will be added in construction in many areas. With the change of specific environmental factors, these substances will be gradually reduced to ammonia and slowly released from the wall, making the ammonia concentration in the indoor air rise sharply. At the same time, the pollution caused by some backward industries and heavy i...
