In recent years, more and more water purifier brands have entered the market and won the favor of customers. At present, the physical water purification methods of water purifiers on the market are basically two types: filtration and ultraviolet sterilization. The filtration effect is mainly determined by the material of the filter element, and the ultraviolet sterilization effect is mainly determined by both the ultraviolet germicidal lamp and the shell sterilizer. As far as the ultraviolet sterilizing method is concerned, the straight-through ultraviolet sterilizer is generally used at present, that is, the water inlet and outlet are arranged on the shell of the sterilizer, and the ultraviolet sterilizing lamp is fixed inside. The UV-permeable quartz tube is covered. When working, water enters from the water inlet and then flows out from the water outlet in a straight line. In this way, the water flow path is linear, and at the same time, the water flow passes through the sterilizer without hindrance. The water flow speed is faster, sometimes Often can not reach enough sterilization time, can not guarantee qualified sterilization rate.

Moreover, since the penetrating power of ultraviolet radiation in water will attenuate with the increase of distance or the thickening of the water layer, the bactericidal effect of the upper layer of water is not consistent with that of the lower layer of water in the same period of time.
