Problems solved by technology
Generally, wearable particle purification devices can only purify the air, but cannot detect the concentration of particles in the air purified by the particle purification device, that is, there is no way to know the concentration of particles in the air inhaled by the human body
If the particle detection device is directly installed at the clean air outlet of the particle purification device, and the particle concentration of the clean air is detected in real time, the detection result will be affected by the moisture in the user's exhalation, the high voltage of the negative ion output terminal and the interference of the magnetic field

The invention discloses an air purifier and a particle concentration detection method, which are used for detecting the particle concentration in the air purified by the purification device. Wherein, the air cleaner includes a purification device, a first detection device and a processor. The purification device is used to purify the air within a predetermined range around the purification device; the first detection device has a first predetermined distance from the purification device, and can obtain the concentration of particulate matter before purification by the purification device; the processor is used for the real-time status obtained by the first detection device Calculate the concentration of particulate matter before purification and the pre-stored concentration relationship before and after purification to calculate the concentration of particulate matter after purification corresponding to the particle concentration before purification in real-time. The corresponding post-purification particulate matter concentration is obtained.
Description
technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air purifier and a particle concentration detection method. Background technique [0002] Haze is a state of air pollution, and it is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (particles with a particle size of less than 2.5 microns) is considered to be the "culprit" of haze weather. After PM2.5 is inhaled into the human body, it will enter the bronchi and lung cavities, interfere with the gas exchange in the lungs, and cause diseases including asthma, bronchitis, and cardiovascular and cerebrovascular diseases. These fine particles can also enter the blood through the bronchi and alveoli, among which Soluble substances, harmful gases, heavy metals, etc. dissolve in the blood, which is more harmful to human health. [0003] Severe and above-level air pollution occurs frequentl...
