The invention has the beneficial effects that:
1. the invention discloses a water purifying device with a sterilization function, and particularly relates to an active carbon filter layer with sterilization, filtering and adsorption functions. The water purification equipment provided by the invention is provided with the double-layer filtering of the filter screen and the active carbon filter layer, the filter screen can block large-particle impurities in water, and the active carbon filter layer can adsorb and filter micro particles and impurities in water, so that the content of finally obtained water impurity components is reduced to the minimum. Meanwhile, the purification equipment combines the active carbon filter layer and the ultraviolet germicidal lamp to carry out full sterilization and bacteriostasis treatment on the water to be purified, so that the content of bacteria in the purified water is greatly reduced, and the effect that the bacteria are not easy to breed even if the purification equipment is used for a long time is achieved.
2. The activated carbon has the advantages of high mechanical strength, high adsorption speed, high purification degree, difficult powder removal and long service life, can effectively remove harmful substances such as odor, chlorine, cyanogen and various heavy metal ions and decolor, has a purification effect on water quality, can remove peculiar smell and improve the purity of water. But the antibacterial performance of the activated carbon is poor, and the activated carbon antibacterial material with stronger antibacterial property and bactericidal property is prepared by adsorbing and grafting the polyhydroxy hyperbranched polyester modified astaxanthin on the activated carbon. After the water purification equipment disclosed by the invention uses the activated carbon filter layer prepared from the activated carbon antibacterial material, the bacteria content in purified water is inhibited, and the antibacterial effect surface is excellent after long-term use.
3. Astaxanthin is a mauve crystal extracted from aquatic products such as shrimps, crabs and the like, and has the ability of quenching singlet oxygen and capturing free radicals which is more than 10 times higher than that of beta-carotene and more than 100 times stronger than that of vitamin E, and people also refer to the crystal as super vitamin E. The antioxidant property, the coloring property and the property of enhancing the immunity of the organism of the astaxanthin are widely accepted. Countries such as the United states and the like have permitted to be used as food additives for production, and have wide development prospects as natural food additives. But the astaxanthin is not high in stability, easy to oxidize and easy to decompose by visible light, and the polyhydroxy hyperbranched polyester modified astaxanthin obtained by modifying the astaxanthin with polyhydroxy hyperbranched polyester is more stable. The surface of the polyhydroxy hyperbranched polyester contains a large number of ester hydroxyl groups, which can form interacting hydrogen bonds with unstable polar hydroxyl groups and ketone groups in astaxanthin molecules, and meanwhile, the hydrophobicity of the surface of a molecular chain of the astaxanthin is improved, so that the astaxanthin can be more stably present in water after being modified. And after the activated carbon material is treated by malic acid, carboxyl on the surface of the activated carbon material can be combined with the modified polyhydroxy hyperbranched polyester on the surface of the astaxanthin, so that a stable structure can be formed, and the astaxanthin can be stably adsorbed and grafted on the surface of the activated carbon.

Comparative example
The utility model provides a water purification unit with function of disinfecting, specifically sets up with embodiment 1, and the difference lies in the material difference of active carbon filter layer, specifically is: the active carbon filter layer is processed by active carbon material and edible adhesive.
For a more clear illustration of the present invention, the water purification devices of the different activated carbon filter layers prepared in example 1 of the present invention and comparative example were subjected to a comparison of purification with water introduced from the same sample and at the same flow rate during the experiment, and the results of the other settings (including uv lamp sterilization) were the same as those shown in table 1.
TABLE 1 Sterilization Effect of different activated carbon filtration layers
As is clear from table 1, the water purification apparatus of example 1 of the present invention has an excellent and stable sterilization effect, and can maintain a sterilization rate of 99% or more even after 30 days of use. The bactericidal effect is better in the comparative example, perhaps the effect of the less and ultraviolet lamp of bacterium that accumulates in the water purification unit can also keep, and after continuing to use for 30 days, bactericidal performance glides by a wide margin, probably the bacterium accumulation in the water purification unit is too much, and the ultraviolet lamp receives the restriction of penetrability, has weakened in the aspect of bactericidal effect to lead to bactericidal performance to descend. The activated carbon filter layer in the embodiment 1 of the invention has the functions of filtration and sterilization, so that a better sterilization effect can be obtained by matching with ultraviolet lamp sterilization.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
