Air purifying and sterilizing device with the ability to remove fine dust, bacteria, and viruses}

The present invention relates to an air purification and sterilization device that can improve air quality by sterilizing and purifying the air inside or indoors of a vehicle. More specifically, it can be easily installed inside or indoors of a vehicle, and can be used to improve air quality by sterilizing and purifying the air inside or indoors of a vehicle. Contaminants such as dust are removed using a filter, and at the same time, bacteria and viruses floating in the air, such as corona, are removed using a UV light source. The air is circulated inside the air purification sterilization device and exposed to bacteria for a long time. and an air purification and sterilization device with an improved form of fine dust, bacteria and virus removal function that can maximize the sterilization effect of viruses such as coronavirus.

Nowadays, since we spend most of our daily life indoors, it is important to maintain the health of the human body living in residential or office spaces by creating a comfortable indoor environment.

However, as industrialization progresses, indoor air has become more polluted than outside, and even microscopic particles such as various bacteria, mold, viruses, and super bacteria that have a harmful effect on the human body and fine particles such as various dust remain throughout the indoor life. People who do this are exposed to unsanitary environments.

Therefore, recently, various air purification devices and sterilization and disinfection devices for indoor spaces have been developed.

In particular, in the case of public transportation such as buses and subways, the internal air is easily polluted by users and at the same time, viruses spread easily and cause the spread. Therefore, it is necessary to sterilize and antibacterial the internal air of public transportation such as buses and subways. It is considered more important than anything else.

Indoor sterilizing and purifying devices for sterilizing and purifying the air in such indoor spaces are generally developed to the extent of adding a component that exerts a sterilizing function to an air purifier, or a sterilizing light lamp that irradiates sterilizing light such as ultraviolet rays is used in the indoor space for a considerable period of time. It remains in a very simple form to the extent that it is placed to sterilize and disinfect the indoor space.

The air sterilization and purification device registered in Patent No. 10-2031698 (registration date: October 7, 2019) is a conventional technology of previously known sterilization and purification devices. It is a purification device that has an intake port for sucking in polluted air and an exhaust port for discharging clean air. A pre-filter that primarily separates dust from the contaminated air sucked in through the main body and the intake port, and secondarily removes odors and bacteria from the contaminated air from which dust has been removed by passing through the pre-filter through deodorizing and antibacterial effects. a carbon filter, first and second photocatalyst filter modules having a photocatalyst filter and a sterilization lamp to finally sterilize and purify the contaminated air passing through the carbon filter through two catalytic reactions using a photocatalyst, and the exhaust port. It is characterized in that it includes a blowing fan that simultaneously suctions contaminated air through the intake port and discharges clean air through the exhaust port.

Another conventional technology, Patent Registration No. 10-2192150 (registration date: October 26, 2020), is an IOT smart air purification device with an easily attachable and detachable sterilization unit frame and a clean outdoor air intake structure, which purifies polluted indoor air in buildings. An air purifying device that includes an air purifying device main body that controls a purifying process by sucking indoor polluted air and a purifying process by introducing clean outdoor air, and which forms a part of the air purifying device main body and sucks indoor polluted air and supplies outdoor air. A purification chamber equipped with a fan motor and a damper that controls the air purification chamber, an air purification filter module provided in a part of the purification chamber to purify indoor polluted air and outdoor air by filtering, sterilizing and adsorbing it, and a part of the air purifying device main body. It is characterized by including a controller that controls the operation of the air purification device.

However, in general indoor sterilizing and purifying devices, the efficiency of the sterilizing function is relatively high in the area near the sterilizing light lamp where the sterilizing light is irradiated, but as the distance from the sterilizing light lamp increases, the efficiency of the sterilizing function decreases sharply, causing overall damage to the indoor space. There is a problem that the sterilization effect is very minimal, and even in the case of simple air sterilization purifiers, other than the function of purifying the air by removing fine dust, the efficiency of the sterilization function is relatively low.

In addition, even if the sterilization function is improved, the air introduced into the sterilization and purification device is forcibly discharged by the discharge fan, so the time it remains inside the sterilization and purification device for sterilization is very insufficient, which reduces the sterilization effect of the air. There is a problem.
