Description

Technical Field

[0001] The present invention belongs to the field of household air purification, and more specifically, relates to an air purification device with integrated pulsed strong light sterilization. Background Art

[0002] With the development of science and technology, the emission of automobile and industrial waste gas, the harmful gas emitted by indoor building materials, the mold, virus, formaldehyde, bacteria, fungi, etc. that grow in indoor humid places have caused great harm to the living environment. Studies have shown that modern people spend 80% to 90% of their time indoors, so the quality of the air in the indoor environment has a great impact on the health of the human body. High-quality indoor air is very important for human health. The air purifier that came into being has become a widely used product in daily life.

[0003] The main purification methods of air purification devices on the market today are as follows: (1) Filtration method: using a filter layer to filter, intercept, and adsorb suspended matter, harmful substances, and relatively large air impurities in the air to achieve physical air purification. This method has been able to achieve a 99.97% filtration effect with the continuous development and progress of filter materials. Although this method has a certain purification effect, the saturation and aging of the material will affect the subsequent purification effect after the use time increases. (2) Electrostatic adsorption technology, ozone air disinfection technology, negative ion air disinfection technology, photocatalytic oxidation technology, and ultraviolet air sterilization technology. Compared with the filtration method, this method does not require filter materials and can act on parts that cannot be purified by the filtration method. However, electrostatic adsorption technology can only adsorb substantial particles and is ineffective for gas molecules, and the sterilization efficiency is limited; although ozone air disinfection technology has a relatively good effect, the secondary pollution generated by ozone is harmful to the human body; negative ion air disinfection technology is similar to electrostatic adsorption technology and can only adsorb substantial particles; photocatalytic technology has very high requirements for temperature and humidity, and there are many restrictions on the disinfection scheme, which is not suitable for home use. Ultraviolet technology is harmful to the human body. (3) Biological method: Bioenzyme is a newly developed artificial enzyme that has an excellent purification effect on industrial pollution components in the air. However, since this technology is often used in the industrial field, it is difficult to miniaturize and has relatively high requirements for the use environment, so it is not suitable for home use.
