Modular indoor air purification device

Abstract

The invention discloses a modular indoor air purification device, and relates to the field of air purification. The modular indoor air purification device comprises a machine body, a mounting structure, a purification module and an air supply system; an air inlet and an air outlet are formed in the machine body, the air inlet and the air outlet communicate with exterior and an internal cavity of the machine body respectively, and the air inlet communicates with the air outlet; the mounting structure is fixed connected in the internal cavity of the machine body, and a mounting window is arranged on the mounting structure and located on the cross section of an air channel between the air inlet and the air outlet; the purification module comprises a formaldehyde remover and a particulate pollutant remover, and one of the formaldehyde remover and the particulate pollutant remover is arranged in the mounting window; and the air supply system is used for enabling external air to flow from the air inlet to the air outlet. The modular indoor air purification device has the advantages that the formaldehyde remover and the particle pollutant remover are mutually independent, and formaldehydeor particle pollutants can be selected to remove according to needs.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a modular indoor air purification device. Background technique [0002] Indoor air pollutants mainly include particulate matter and volatile chemical substances. Among them, formaldehyde released from decoration materials and furniture has attracted the most attention. In view of the serious harm of formaldehyde, removing formaldehyde from indoor air has become the first choice for new home residents. Before people move into a new room, they often need to use professional equipment to eliminate the residual formaldehyde of various decorations to the greatest extent. [0003] Existing air purifiers mainly filter out tiny particles in the air. The patent with the authorized notification number CN205878377U discloses a formaldehyde air purifier. The formaldehyde air purifier adds a formaldehyde-removing activated carbon filter containing an adsorbed formaldehyde decomposition cataly...

Problems solved by technology

[0004] Existing air purifiers take the removal of PM2.5 particulate matter as the first choice function, and the removal of formaldehyde is only an incidental function, so they have to use HEPA filters with higher wind pressure and smaller air volume, and in order to ensure the removal efficiency of PM2.5, only It can sacrifice the size and space of the formaldehyde removal device, resulting in low formaldehyde removal efficiency and cumulative removal amount, and cannot guarantee air quality, especially when used in a newly decorated room. This defect will cause the user to significantly exceed the formaldehyde content. If only the function of removing formaldehyde is considered, and the function of removing PM2.5 particles is not considered, the specific structure and operating parameters of the air purifier are configured for the function of removing formaldehyde. When the formaldehyde release rate drops to a safe level, the function of removing formaldehyde will be idle and the function of removing PM2.5 particles will be lost. Users have to buy new purifiers to meet the indoor air purification requirements and increase costs; if only using HEPA filters On the basis of increasing the volume of the formaldehyde removal unit, although the total amount of formaldehyde removal can be increased, the volume of the air purifier will be larger, the structure will be complicated, and the working efficiency of the whole machine will be reduced.
