Environment-friendly air purifying device

Abstract

The invention provides an environment-friendly air purifying device which comprises an outer shell and an inner shell, wherein a hollow air cylinder penetrating through an inner shell wall is arrangedin a first empty cavity; an outer shell air inlet is arranged on an outer shell wall, and an outer shell air outlet is arranged at the upper end of the outer shell; a piston is arranged in the air cylinder in a sliding mode, a pm10 filter screen is arranged on the outer side of an air cylinder air inlet, and a pm2.5 filter screen is arranged on the inner side of an air cylinder air outlet; a groove penetrating through the piston is formed on the piston in the shell height direction, a rotary hair brush mechanism is arranged in the groove, the rotary hair brush mechanism comprises a rotating shaft, the rotating shaft is arranged in the groove in a rotary mode in the shell height direction, a rotating wheel is arranged at one end of the rotating shaft, a hair brush is arranged on an outer wall of the rotating shaft, the rotating wheel is in contact with an inner wall of the air cylinder, and the hair brush is in contact with the pm10 filter screen; the piston is driven by a motor to move. The air purifier can filter air in a classified mode, the pm2.5 filter screen can be cleaned by the hair brush in time, the pm2.5 filter screen is prevented from being often plugged by large-particle pollutants, a work period of the air purifier is improved, and the air purifier has a simple structure and a high-efficiency purifying efficiency.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to an environment-friendly air purification device. Background technique [0002] PM2.5, also known as particulate matter that can enter the lungs, refers to particulate matter in the atmosphere with a diameter less than or equal to 2.5 microns. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particulate matter, PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, has a long residence time in the atmosphere, and has a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. After being inhaled into the human body, it will directly enter the bronchi, interfere with the gas exchange of the lungs, cause diseases including asthma, bronchitis and cardiovascular di...
