Air purifier

Abstract

The invention discloses an air purifier which comprises a purifier main machine, an air purification assembly is arranged in the purifier main machine. One end of the purifier main machine is a freshair output end; the other end is an air input end; a filter screen is mounted on the outer side of the air input end; an air inlet cavity in the purifier main machine is sealed through the filter screen; a sealing plate is movably mounted in the air inlet cavity; the sealing plate divides the air inlet cavity into two closed cavities; an elastic air bag is fixedly arranged on the side, opposite tothe filter screen, of the sealing plate, an air inlet channel is formed in the inner wall face of the air inlet cavity, the air inlet channel communicates the outside with the air inlet cavity, and when the purifier main machine does not work, the sealing plate seals the air inlet channel and blocks contact extrusion between the outside and the air inlet cavity and between the outer side face ofthe elastic air bag and the filter screen face. According to the air purifier, rapid dust removal of an air inlet screen can be achieved, the efficiency is higher, and air purification is better facilitated.

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, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. [0003] However, due to the poor air quality nowadays, the working principle of the air purifier is to inhale the outside air and exhale fresh air. Due to the poor air quality, a filter screen is generally installed at the air input end of the air purifier. Intercept the inhaled air to achieve a coarse filter. Because the current filter is fixed, after a long time of use, a large amount of dust will adhere to the mesh in the filter and the filter, so...

Problems solved by technology

[0003] However, due to the poor air quality nowadays, the working principle of the air purifier is to inhale the outside air and exhale fresh air. Due to the poor air quality, a filter screen is generally installed at the air input end of the air purifier. Intercept the inhaled air to achieve a coarse filter. Since the current filter is fixed, after a long period of use, a large amount of dust will adhere to the mesh in the filter and the filter, so it needs to be cleaned regularly. Due to the filter The net is fixed, so it is difficult to clean, especially where the mesh is blocked, it is difficult to conduct, and this cleaning method is manual cleaning, which is very inconvenient
