Along with the improvement of living standard of people, the requirement on the quality of drinking water is higher and higher, and in order to ensure the safety of drinking water, water purifiers are purchased by many families and have simple filtration, for example, the water purifiers only rely on PP cotton, activated carbon, compressed carbon and the like, and have lower cost; it is also preferable, for example, to filter tap water thoroughly through a reverse osmosis membrane, such as a water purification machine; and the ultrafiltration water purifier filters tap water through an ultrafiltration membrane to reach the standard of kitchen and drinking water. The water purifier is very effective in purifying water, but generally neglects the problem that bacteria grow after the water purifier is used for a long time. For example, in order to improve the taste and adsorb organic matters, the water purifier is provided with an activated carbon filter element, but the problem of self-pollution of an activated carbon medium is ignored, and the water purifier is like a super sponge, and can adsorb a large amount of toxic and harmful pollutants and simultaneously propagate a large amount of bacteria in micropores of the water purifier. Therefore, many of the existing water purifiers are equipped with an overflowing ultraviolet LED germicidal lamp, and for flowing water, the germicidal method is generally to install the ultraviolet LED germicidal lamp in the water pipe, and ultraviolet rays generated by the ultraviolet LED germicidal lamp are used to irradiate the water flowing in the water pipe to realize disinfection. However, the ultraviolet LED germicidal lamp has limitations, about 98% of its power can be used for heat dissipation, if there is no water flow for heat dissipation, the ultraviolet LED germicidal lamp will be overheated, and the temperature above 60 ℃ will be reached, so that the germicidal effect of the LED germicidal lamp will be greatly reduced.
