Description

UV LED function enhanced air purifier

The invention relates to an air purifier, in particular to an ultraviolet LED function enhanced air purifier.

Modern office buildings, hospitals, homes, apartments and schools use a fully enclosed building structure for energy efficiency reasons. Although this closed design has good thermal insulation effect, the overall building can only be ventilated through the air conditioning circulation system, which greatly reduces the air renewal rate of the building and deteriorates the indoor air quality. Deterioration of indoor air quality creates favorable conditions for the growth of microorganisms such as bacteria, viruses and dust mites. Microorganisms such as bacteria, viruses, and dust mites adhere to inhalable particulate matter. As the breath penetrates deep into the human lung, the damage is difficult to reverse after it is formed, and gradually accumulates and deepens over time.

Respirable particulate matter that adsorbs microorganisms such as bacteria, viruses and dust mites can be suspended in the air for a long time. When inhaled into the human body, it can easily cause diseases such as bronchitis, allergic rhinitis, pneumonia, asthma and even lung cancer, leading to cardiopulmonary dysfunction and even failure. Therefore, indoor air has become a "stealth killer" that endangers human health.

With the improvement of people's living standards and the continuous renewal of health concepts, people gradually realize the importance of air quality, and also use some facilities to purify the air. At present, air purifiers are generally classified into mechanical, electronic, and ionic types, and each has different advantages and disadvantages. among them, Mechanical air purifiers use a filter assembly to filter out foreign matter in the air passing through the filter, such as mold, pet hair and pollen, to purify the air. Although the mechanical air purifier can effectively remove foreign matter in the air, it needs to periodically replace the filter, and can not remove odor, virus, bacteria and the like; the electronic air purifier is to pass air through the positive electrode with a certain spacing. Between the plate and the negative plate, the foreign matter in the air passing through the positive plate is positively charged, thereby adsorbing the positively charged foreign particles to the negative plate to achieve the purpose of purifying the air. The electronic air purifier has the advantage of small volume, but similar to the mechanical air purifier, it cannot remove substances such as odor, virus or bacteria; the ion air purifier inputs ions into the air to cause the foreign particles to adsorb the ions. In order to achieve the purpose of purifying the air, the ionic air purifier does not use a fan and has the characteristics of low noise, but it cannot remove odor, virus or bacteria.

Therefore, the prior art air purifier cannot achieve effective removal of odor, cigarette flavor, virus, bacteria, and free formaldehyde, and the effect on air purification is not satisfactory.
