Description

A multifunctional air purifier and disinfector for indoor use

technical field

The utility model relates to an air purifying machine, in particular to a multifunctional air purifying and disinfecting machine for indoor use.

Background technique

Air is one of the natural resources for human survival, but viruses, bacteria, dust, and volatile organic compounds in the air will harm people's health unknowingly. At present, the rapid global spread of the new coronavirus is seriously affecting people's health and quality of life. Disinfection and purification of air has also received extensive attention, especially by engineers in the medical field.

At present, there are many types of air sterilizers on the market. They sterilize the air through the principles of filtration, purification and sterilization. Some models can also remove organic pollutants such as formaldehyde and phenol in the indoor air. There are also ozone generators, but most of the products have single or incomplete functions, and it is difficult to achieve a full range of air purification and disinfection. Recently, it has also been reported that adding disinfectant to the water and discharging it into the room to achieve the purpose of dust reduction and sterilization, but this solution will produce drug residues in the indoor air, and will also cause certain damage to the human body.

Utility model content

Ultraviolet disinfection lamps use ultraviolet rays emitted by mercury lamps to achieve sterilization and disinfection functions. Ultraviolet disinfection technology has extremely high sterilization efficiency, and the sterilization efficiency can reach 99% to 99.9%. The bacteria and viruses carried on the clothes can be killed by the ultraviolet disinfection lamp for about 5 minutes. It can also be used to sterilize the indoor spaces such as laboratories and operating rooms. The bacteria in the air can be killed by the irradiation for about 30 minutes. . The principle of ultraviolet disinfection: mainly acts on the DNA of microorganisms, destroys its DNA structure, and makes it lose the function of reproduction and self-replication to achieve the purpose of sterilization and disinfection. Ultraviolet sterilization has the advantages of being colorless, odorless, and chemical-free, but without proper protective measures, it can easily cause huge harm to the human body. In addition, the appropriate power and quantity of ultraviolet disinfection lamps need to be selected according to the area of the specific place to achieve the ideal sterilization effect; the environment also has a certain influence on the sterilization effect of ultraviolet disinfection lamps, and high humidity or dust will reduce the sterilization ability of the disinfection lamp; Frequently replace the disinfection lamp, usually after 8,000 hours of use, the lamp needs to be replaced in time; disinfection cannot be completed for the parts that cannot be irradiated by ultraviolet rays.

The air filter is mainly composed of a filter element and a shell. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and can also solve indoor and underground spaces due to decoration or other reasons. , the problem of volatile organic compounds in the car air pollution. However, the filter element is a consumable item and needs to be replaced frequently. Even if the air quality is good, the same filter element cannot be used continuously for more than half a year. Otherwise, after the filter material is saturated with adsorption, it will release harmful substances and become a "pollution source".

Ozone generator is a device used to produce ozone gas (O ₃ ). O ₃ has strong oxidizing and bactericidal properties, and is one of the strongest oxidants in nature. Its sterilization process is a biochemical oxidation reaction, mainly This is achieved in the following forms: (1) oxidatively decompose the enzymes needed to decompose the internal glucose of bacteria, causing the bacteria to inactivate and die; (2) acting on nuclear substances in bacterial cells, such as purines and pyrimidines in nucleic acids, destroying their organelles and DNA. , RNA, the metabolism of bacteria is destroyed, resulting in bacterial death; (3) double-stranded reaction with bacterial cell wall lipids, through the cell membrane tissue, invading cells, acting on the lipoproteins of the outer membrane and the internal lipopolysaccharides, making bacteria Permeability distortion occurs and dissolves to death; (4) acts on the 4 polypeptide chains of the capsid protein of the virus, and damages the RNA and destroys the protein that forms it. After the phage is oxidized by ozone, its epidermis is broken into many fragments, from which many ribonucleic acid is released, which interferes with its adsorption to the deposit. In addition, O ₃ is a gas, which can quickly diffuse into the entire sterilization space, and there is no dead angle for sterilization; O ₃ will automatically reduce to oxygen after 30-40 minutes in the air, and the decomposition rate in aqueous solution is faster, there is no chemical residue or Secondary pollution and other issues; can also remove odors in the air. But at the same time, the extremely strong oxidizing property of O ₃ will also cause damage to the human body. The International Ambient Air Quality Standards (NAAQS) proposes that the limit concentration of O ₃ that people can accept within one hour is 260 μg/m ³ , However, exercising in the environment of 320μg/m ³ O ₃ for 1 hour will cause cough, dyspnea and decreased lung function.

Negative air ion generators can generate negative air (oxygen) ions (NAI). As one of the important members of reactive oxygen species, NAI is similar in structure to superoxide radicals due to its negative charge. It has a strong redox effect and can destroy the barrier of bacterial virus charge and the activity of bacterial cell active enzymes; in addition, NAI can settle suspended particulate matter in the air. However, the concentration of negative ions is not as high as possible. When the concentration exceeds 106/cm ³ , negative ions will have certain toxic and side effects on the human body.
