Air purifier

Abstract

The invention discloses an air purifier which is capable of adjusting an effective purification space and internal and external air circulation and is convenient to install. The air purifier comprises a purifier body and a filtering mechanism arranged in the purifier body. The purifier body comprises a plurality of sub-purifiers independent to one another, first indoor air inlets, second indoor air inlets, indoor air outlets and outdoor ports, wherein the first indoor air inlets, the second indoor air inlets, the indoor air outlets and the outdoor ports are arranged on the sub-purifiers. Branch-shaped exhaust pipe assemblies are connected to the outdoor ports, collected in a branch shape and connected with at least a part of main pipes arranged outside a room. According to the air purifier, indoor and outdoor air circulation can be achieved, a plurality of air inlet pipes and a plurality of air outlet pipes can be installed only by drilling a through hole in the wall surface, the air inlet pipes and the air outlet pipes are designed in a branch shape and arranged in a sleeving mode, and the situation that the beautiful appearance is affected due to the fact that multiple holes are drilled in the wall surface is avoided. The air purifier provided by the invention is formed by combining the multiple independent sub-purifiers, and one or some of the sub-purifiers can be selected to be started according to the size of the purification space.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purifier. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, etc., refer to the ability to absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria , allergens, etc.), products that effectively improve air cleanliness. However, the existing air purifiers require the indoor to be closed to have a better air purification effect. Longer time will lead to an increase in indoor carbon dioxide concentration and lower comfort. Air purifiers with internal and external circulation generally include air inlet pipes and air outlet pipes. Sometimes it is necessary to drill multiple through holes on the wall, which is troublesome to install and affects the appearance; the purification space of air purifiers on the market is fixed, and the effective ...

However, the existing air purifiers require the indoor to be closed to have a better air purification effect. Longer time will lead to an increase in indoor carbon dioxide concentration and lower comfort. Air purifiers with internal and external circulation generally include air inlet pipes and air outlet pipes. Sometimes it is necessary to drill multiple through holes on the wall, which is troublesome to install and affects the appearance; the purification space of air purifiers on the market is fixed, and the effective air purification space cannot be adjusted according to the size of the indoor space, resulting in poor air purification effect. good or waste of energy
