Drinking water terminal sterilizing water purifier

Abstract

The invention relates to a drinking water terminal sterilizing water purifier which includes a tube body, a water inlet and a water outlet. The water inlet and the water outlet are arranged on two ends of the tube body, in which a sterilizing layer, a water purifying later and a heavy metal ion removing layer are successively arranged from the water inlet to the water outlet in a laminating manner, wherein the sterilizing layer is composed of a high-polyiodinate resin, the water purifying later is composed of granular active carbon and active carbon fibers, and the heavy metal ion removing layer is composed of heavy metal nano-spherical particle and cation exchange resin. In the sterilizing layer, the high-polyiodinate resin can instantly kill various bacteria and viruses harming human health in water within 0.5 s and is free of generating bacteria and secondary pollution in itself. Under the same sterilizing effect, compared with a conventional water purifier structure, the sterilizing water purifier is greatly simpler. The water purifying later can neutralizing and adsorbing free iodine in water, can removing organic pollutant and residual chlorine in water, and can improving mouthfeel of water. The heavy metal ion removing layer can effectively remove heavy metal ions in water and reduce hardness of water. The sterilizing water purifier is not liable to be blocked, is long in service life and can be matched with other filtering methods.

[0002] For life, water is indispensable, and humans are no exception. In extreme environments, the human body may become metabolically disordered beyond rescue if it lacks water for 24 hours; even under relatively comfortable conditions of temperature, humidity, and air pressure, a It is difficult for an adult to last for more than 5 days without water intake. The common process of nanofiltration or reverse osmosis water purifiers in the past is non-woven fabric, coarse filter granular activated carbon (GAC), fine filter granular activated carbon, ultrafiltration membrane, nanofiltration Membrane or reverse osmosis membrane and post granular activated carbon, a major hidden danger of this water purifier is that if the water purifier has not been used for a period of time, or just for one night, the outlet and rear of the water purifier will A large number of bacteria will grow inside the granular activated carbon filter, making the total number of colonies in the effluent not meet the requirements of GB5749-2006. Due to the porous characteristics of the rear granular activated carbon, it is very conducive to the growth of bacteria. After the water flows through the water purifier, the activated carbon While sterilizing the water, it will also bring out the bacteria carried by the activated carbon itself, causing secondary pollution. This is a common problem in all water purifiers sterilized by activated carbon

[0003] In order to overcome the problem of secondary pollution caused by activated carbon sterilization, water purification technologies such as ultraviolet sterilization and ultrafiltration sterilization have appeared on the market. Although this sterilization effect is better than activated carbon, no matter what kind of water purifier, the final terminal There will still be the problem of excessive bacteria in the effluent, and it will inevitably cause the structure and process of the water purifier to become more complicated, the manufacturing cost will rise sharply, the power consumption will increase, and the service life of the water purifier will be shortened
