Desktop air purifier

Technical Field

The utility model relates to an air purification field especially relates to a desktop air purifier.

Background

It is well known that smoking is a health hazard, but many people do not know that second hand smoke is more harmful than first hand smoke. Second-hand smoke has over 4000 harmful chemicals and dozens of carcinogens, such as tar, ammonia, nicotine, suspended particulates, PM2.5, polonium-210, etc. Second-hand smoke is a generic term for "mainstream smoke" exhaled by smokers and "sidestream smoke" released into the environment upon combustion of cigarettes and other tobacco products, the constituents of which differ from the simple "mainstream smoke". Because the combustion of the side stream smoke is insufficient, the harmful components are higher than that of the main stream smoke, for example, the content of carbon monoxide is 5 times higher, the content of tar and nicotine is 3 times higher, and the content of nitrosamine is 50 times higher. These substances are very toxic, for example, 300 rabbits or 500 mice can be poisoned by 1 gram of nicotine. Thus, inhaling second-hand smoke is more harmful than actively smoking a smoker. Meanwhile, China is the largest tobacco producing and consuming country in the world and is one of the countries with the largest population of dead people caused by tobacco. Therefore, the harm of the second-hand smoke to the Chinese people is reduced or eliminated. In daily household life and office areas, family members, staff or guests smoke, the second-hand smoke in the room is easy to spread and easily absorbed by people around the room, cough diseases such as laryngitis, tracheitis and emphysema are easy to cause, and the risk of cancer is increased.
