Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a portable air sterilizer. Background Technology

[0002] In modern society, people are paying increasing attention to a healthy living environment. With the acceleration of urbanization and the increase in population density, indoor air pollution has become more and more prominent. On the one hand, modern buildings are becoming increasingly airtight, which has improved the energy efficiency of buildings to some extent, but it has also made it difficult for indoor air to circulate fully with the outside, making it easy for pollutants to accumulate indoors. These pollutants include bacteria, viruses, mold, pollen, dust, harmful gases from decoration, and pet dander. Long-term exposure to such a polluted environment can easily lead to respiratory diseases, allergic reactions, and may even cause more serious health problems.

[0003] Traditional air purification devices, such as air purifiers, primarily focus on filtering particulate matter in the air, with limited ability to disinfect bacteria and viruses. However, in certain special locations, efficient air disinfection is crucial to prevent the spread of disease. In daily life, people face varying degrees of air pollution risks when traveling, on business trips, or engaging in outdoor activities, necessitating portable air disinfection devices that can be used anytime, anywhere to protect personal respiratory health. With continuous technological advancements, ultraviolet disinfection, plasma disinfection, and ozone disinfection have gradually matured and been applied to the air treatment field. Various pathogenic microorganisms, such as bacteria, viruses, and fungi, exist in the air. These microorganisms can enter the human body through respiration, causing various diseases. In hospital environments, airborne pathogens can easily spread between patients and medical staff, leading to hospital-acquired infections. Disinfecting and filtering the air can effectively reduce the number of these microorganisms and lower the risk of infection. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable air sterilizer, which aims to improve the problem in the prior art that if air cannot be filtered and sterilized, microorganisms in the air can enter the human body through respiration, causing various diseases.
