Abstract

The invention relates to the technical field of air purifiers, and particularly discloses a negative-pressure type air purifier provided with a replaceable filtering structure. The air purifier comprises an air purifier outer box body; a filtering inner cavity is formed in the air purifier outer box body; an air inlet and an air outlet are formed in the left side surface and the right side surfaceof the air purifier outer box body correspondingly; a rectangular groove is formed in the front side surface of the air purifier outer box body; a side cover plate is rotationally connected to the rectangular groove through a hinge; and a locking mechanism is arranged between the other end of the side cover plate and the air purifier outer box body. According to the negative-pressure type air purifier provided with the replaceable filtering structure, the replacement process of a filtering layer is relatively simple, the operation steps are simpler, the defects that filtering nets close to porous isolation plates are required to be taken out sequentially and then the to-be-replaced filtering nets can be replaced during replacement of negative-pressure type air purifiers in the prior art are effectively overcome, and the air purifier is novel in mounting structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of air purifiers, and specifically discloses a negative pressure air purifier with an replaceable filter structure. Background technique [0002] Air purifier, also known as "air cleaner", refers to the ability to absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.) , an electrical product that effectively improves air cleanliness, and is mainly used in households, businesses, industries and buildings. [0003] Air purifiers often need to be equipped with multi-layer filters to remove different harmful components in the air and achieve the purpose of purifying the air. However, due to the limited service life of the filter screen, the filter screen in the air purifier needs to be replaced frequently during use, and the filter screen structure in the existing air purifier is not easy to repl...
