Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a portable plasma air purification device. Background Art

[0002] With the development of industrial process, environmental pollution is becoming more and more serious. Air pollution such as inhalable particulate matter, volatile organic compounds, ozone, nitrogen oxides, etc. poses an increasingly serious threat to human health. In particular, for indoor environments or closed spaces, particulate pollutants caused by human behaviors such as cooking and smoking, as well as volatile organic compounds emitted by paints and glues such as decoration and furniture, are hidden in the air that people breathe all the time. Although they are invisible and intangible, they have a huge impact on human health and have become potential hazards. In the field of air purification, especially the technology and equipment used indoors or in closed spaces, people have gradually paid attention to it.

[0003] Among the current air purification technologies, filtration, electrostatics, adsorption and catalysis are conventional technical means. Plasma is an electrically neutral aggregate composed of a variety of active particles and free radicals. It is the fourth form of matter besides gas, liquid and solid. It has high chemical reactivity and conductivity. Among them, low-temperature plasma uses high-energy electrons, ions, free radicals and other active particles to excite, ionize and dissociate pollutant molecules in a very short time, thereby achieving the purpose of degrading organic pollutants and sterilizing. It operates at room temperature, reacts quickly and is highly efficient, making it a reliable air purification technology.

[0004] Chinese patent (CN214038839U) discloses a wall-mounted plasma indoor air disinfection and purification device, including a box-shaped casing, which is divided into a plasma disinfection cabin and a power supply cabin. The casing is located at an air inlet on the upper end face of the plasma disinfection cabin, and an air outlet is provided on the lower end face of the casing. The plasma disinfection cabin is connected with a primary filter, a plasma generation module, an ozone catalytic module, and a cross-flow fan in sequence along the air inlet. The power supply cabin is connected with a high-voltage power supply, and the high-voltage power supply is connected to the plasma generation module. On the one hand, it can purify harmful substances such as formaldehyde, benzene, and volatile organic compounds in the air, and can further sterilize and disinfect.

[0005] However, there are some drawbacks in the above-mentioned related technologies. For example, during use, the wall-mounted plasma indoor air disinfection and purification device is not practical and convenient because the use environment is limited by the wall-hanging position, and there is a large idle space between the modules in the housing, resulting in a large overall size of the purification device, which is not convenient to carry, and the heat dissipation efficiency of the power supply is not good enough.
