In Japan, Europe and the United States and other developed countries, the consumption of sterile household appliances has been in a straight upward trend in recent years. There are few household appliances with bactericidal function in the mainland market. Intelligent sweepers that can kill and kill mites while sweeping the floor are rare. In general, this function configuration will appear on some high-end products, and the corresponding price of this type of product is also more expensive than that of ordinary intelligent sweeping robots. At present, there are two types of intelligent floor-sweeping robot equipped with sterilization function on the market: UV sterilization lamp and cold cathode ultraviolet sterilization lamp. There is no obvious difference between the two kinds of bactericidal lamps in appearance, but the cold cathode ultraviolet bactericidal lamps are advanced manufacturing technology and materials because of the mature UV lamp technology. Proscenic's pro-902 is the representative model of using "cold cathode ultraviolet sterilizing lamp". The cold cathode ultraviolet bactericidal lamp equipped with this model can produce 1500 UW/CM2 illumination, kill the influenza virus on the surface of the ground, when used at about 0.3S, the bactericidal efficiency can reach 99.97%. Relatively speaking, it is more effective in killing and killing mites.
