Description

Technical Field

[0001] The present invention relates to the technical field of air purification, in particular to an air purification device and a dust collecting mechanism. Background Art

[0002] With the rapid advancement of industrialization and urbanization, human activities have emitted a large amount of pollutants into the atmosphere, and the air quality problem has become increasingly serious and has become a focus of global attention. In indoor environments, people spend about 80%-90% of their time in closed or semi-enclosed spaces, such as offices, homes, schools, shopping malls, etc., but indoor air is often threatened by multiple pollution sources. Volatile organic compounds (VOCs) such as formaldehyde and benzene emitted by decoration materials, dust and dandruff generated by daily activities, fume particles from cooking in the kitchen, and haze and automobile exhaust components that penetrate through doors and windows outdoors, all cause a sharp decline in indoor air quality. For example, the announcement number CN109847938B discloses an air purification device and a dust collection mechanism, which includes: at least two electrodes, each adjacent two electrodes are opposite and spaced and an air flow channel is formed between the two; a dust collection component is arranged in the air flow channel; wherein at least two electrodes are staggered in the spacing direction to apply low voltage and high voltage, so that a dust removal electric field is formed in the air flow channel; the dust collection component blocks the movement path of charged particles in the dust removal electric field. In the above-mentioned dust collection mechanism, the dust collection component located in the air flow channel is also in the dust collection electric field, which can block the charged particles (such as dust) moving under the action of the dust removal electric field, so that the dust stays on the dust collection component, thereby purifying the air. The dust is collected by the dust collecting component to prevent the electrode surface from being corroded after collecting too much dust, and to prevent the dust removal ability of the dust removal electric field from decreasing due to electrode corrosion. With the extension of the use time, the purification effect of the air purifier can remain stable;

[0003] Although the air purification device in the prior art can meet the needs of use, although this method can intercept particulate matter within a certain particle size range, the filter is prone to clogging. As the use time increases, the air passage resistance increases sharply, which not only reduces the purification efficiency but also significantly increases energy consumption. Frequent replacement of the filter also brings higher use costs and environmental pressures. Moreover, dust accumulated for a long time is very easy to mix with the air and be discharged, and the air purification effect cannot be achieved at all. Summary of the invention
