The present invention relates to a purifying and sterilizing device, and more particularly to a desktop air purifying and sterilizing device for purifying air by using an ozone-free ultraviolet lamp, wherein the outer side is also provided with a detachable type that meets customers' requirements for various shapes. Sleeve.

According to the progress of society and the rapid development of the industrial and commercial industry, people enjoy all kinds of daily necessities that are extremely convenient and comfortable in daily life, but they must also endure various environmental pollutions in the living environment; The impact of air pollution is the most serious. Humans can not eat for a few days, do not drink water for several hours, but they can't breathe for dozens of minutes, and the aerosols present in the air, the exhaust gas from the steam locomotive, and the factory discharge. The black smoke and toxic gases, and even the cigarette gas that people make when they smoke, affect people all the time, so that in the air that people breathe every day, there are various kinds of dust and exhaust gas that will endanger the health of the human body. Bacteria, mold, soot, particles and pollen have caused many people to feel that breathing is not smooth, nose allergies, and even people feel incompetent and tired after inhaling too much of this type of gas.

As a result, many companies have developed various types of air purifiers to purify the surrounding air, improve air quality, and allow people to breathe healthily; however, look at the various types of air on the market. The cleaning machine has a relatively large volume, which causes it to occupy a space on the placement, and the power supply wire may be mixed with pedestrians or obstruct the moving articles, which causes great inconvenience in use. In addition, in order to maintain the indoor air quality, some people will also choose the ozone machine, thinking that through the ozone machine, the virus in the air can kill the light. Or use ozone ultraviolet light with a wavelength of 185 nm to sterilize the oxygen in the air into ozone. However, the National Biotechnology and Medical Industry Policy Council pointed out that ozone does have the function of sterilization and epidemic prevention, but it is not enough to kill the virus; and doctors also cautioned that it is necessary to carefully control the concentration when using the ozone machine. If the concentration is too high, I am afraid It will stimulate the respiratory tract and affect some lung function. Even negative ions are used on the market to improve air quality.
