The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model being described in detail, further to understand the purpose of this utility model, scheme and effect, but is not the restriction as the utility model claims protection domain.
Consult the structure diagram of the water tumbler of Fig. 1 automatic sterilization of the present utility model, as shown in the figure, the water tumbler of automatic sterilization of the present utility model, comprises water tumbler matrix 1, photocatalyst precursor layer 2 and photocatalyst layer 3.Photocatalyst precursor layer 2 is coated on the surface of described water tumbler matrix 1 (surface herein comprises inner surface and outer surface).Photocatalyst layer 3 is sprayed in photocatalyst precursor layer 2.Wherein, photocatalyst precursor layer 2 is one with H
4tiO
5composition layer for film forming agent.The material of water tumbler matrix 1 can be pottery or glass, can be also metal.
Preferably, water tumbler of the present utility model, the thickness of described photocatalyst precursor layer 2 is 0.05～0.2 micron, the thickness of described photocatalyst layer 3 is 0.1～0.5 micron.Photocatalyst layer 3 is a mixture layer being mixed mutually with nano-Ag particles by titanium dioxide nanoparticle, and wherein, the particle diameter of nano titanium oxide is 2～10 nanometers, and the particle diameter of nano-Ag particles is 2～10 nanometers.And water tumbler matrix 1, photocatalyst precursor layer 2 and photocatalyst layer 3 form an integral body.
Specifically, water tumbler of the present utility model is when making: first the method by dipping pulling film forming is coated on photocatalyst precursor layer on water tumbler matrix surface, then in photocatalyst precursor layer, sprays photocatalyst coating.Photocatalyst precursor layer is composition, and said composition is with H
4tiO
5for film forming agent, its solvent is H
4tiO
5and water; Described photocatalyst layer is nano-TiO
2the mixture of particle and nano-Ag particles, nano-TiO
2the particle diameter of particle and nano-Ag particles is 2～10 nanometers.The method of so-called dipping pulling film forming refers to water tumbler matrix is immersed in the colloidal sol of photocatalyst presoma, then with certain speed, lifts water tumbler matrix, after drying and heat treatment, obtains TiO
2film, in order to obtain the film of different-thickness, can repeat above-mentioned steps.Operation is simple for this method, can obtain easily the film of different-thickness.The advantage of this film build method is that the adhesion strength of film forming solution is large, can be on various substrates film forming, thickness can be controlled, the little and narrow pore size distribution range of the membrane aperture that makes, therefore easily application and large area masking.It should be noted that any is that the control of heat treatment temperature is also very crucial, has photocatalytic activity anatase titanium dioxide TiO
2when higher temperature (general more than 550 ℃), can become rutile TiO by Partial Conversion
2, when surpassing 900 ℃, temperature will transform completely, and the TiO of this kind of form
2not there is photocatalytic activity.If therefore temperature control is improper, anatase titanium dioxide TiO
2be easy to change into rutile-type, in the utility model, the heat treatment temperature of employing is 500 ℃, and heat treatment time is 30 minutes, the TiO after heat treatment
2film after tested, more than coating strength can reach 9H.
From application point, on water tumbler matrix, be coated with after photocatalyst precursor layer, can play the function of good antibacterial purifying air, but because dipping pulling film forming method has certain limitation, therefore in order better to bring into play the maximum effect of photocatalyst, in photocatalyst precursor layer, spray one deck photocatalyst layer, the great advantage of spraying is can film formation, does not need heat treatment again.In addition, the film TiO that the method obtains
2coating strength also can reach 5～8H, just a little less than the method with flooding pulling film forming, make the coating strength of film.From application point, this small difference is almost negligible.
Therefore, the water tumbler of automatic sterilization of the present utility model can organically combine two kinds of modes of filming when making, and learns from other's strong points to offset one's weaknesses, thereby makes nano-TiO
2photocatalyst can have been given play to the sterilizing effect of its maximum.
The utility model can kill bacterium, virus under the effect of visible ray, makes the cleaning-sterilizing of water tumbler simple and easy to do.And traditional water tumbler cleaning-sterilizing is to clean with liquid detergent, the method certainly has some chemical residues and stays the health that endangers people in cup, the utility model, compared to traditional water tumbler cleaning-sterilizing, can make people away from the harm of toxic chemical, can improve people's quality of the life.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
