Description

Technical Field

[0001] The utility model belongs to the technical field of air purification, and in particular relates to an air purifier with a PM2.5 dynamic detection function. Background Art

[0002] Air purifiers can absorb, decompose or transform various air pollutants, generally including dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc., effectively improving the cleanliness of the air. In recent years, PM2.5 pollution has gradually become the focus of people's attention. Particles smaller than 2.5μm can directly enter the lungs when inhaled into the human body, and particles smaller than 2μm can directly enter the blood system. When such particles do not carry pathogens, the blood's oxygen carrying capacity will be reduced; once they carry pathogens, the bacteria they carry will also enter the human body, causing a series of diseases and seriously affecting human health. More than 65% of human allergic asthma are related to dust. Therefore, in addition to objectively settling microparticles through the air purifier filter structure, users also attach great importance to purification results and hope to get real-time feedback.
