一种便携式户外净水杯A portable outdoor water purification cup

技术领域technical field

本实用新型涉及到生活净水杯技术领域，具体是一种便携式户外净水杯。The utility model relates to the technical field of domestic water purification cups, in particular to a portable outdoor water purification cup.

背景技术Background technique

当前我国淡水资源极度稀缺，特别是山区等经济落后地区，饮用水不达标已经危害到人的身体健康。水是生命之源，没有水人类就无法生存，而现有的技术很少有一种可以在户外生活考察或者旅游时，能够将水质净化以达到能够饮用的程度，缓解饮用水资源不足，饮用水难以达标的净水杯。At present, my country's freshwater resources are extremely scarce, especially in economically backward areas such as mountainous areas. Substandard drinking water has endangered people's health. Water is the source of life, and human beings cannot survive without water. Few of the existing technologies can purify water to a level that is drinkable during outdoor life inspections or travel, and alleviate the shortage of drinking water resources. Uncompromising water purifiers.

目前市场上售卖一种家用式净水杯，杯体分为两部分，内部存放未过滤水和滤芯，外部大容器存放已过滤的纯净水。这种净水杯不仅体积大，无密封，不方便外出携带，而且净水杯以水自身重力为压力，通过过滤网，所以当水涌过一半以上时，其过滤速率明显降低。市面上此类具有过滤功效的水杯成本太高，价格昂贵，难以在普通居民中推广。净水装置使用范围窄，只能针对家用自来水进行过滤，无法用于野外泉水或者溪水，无法有效清除病菌，具有残留。At present, a household water purification cup is sold on the market. The cup body is divided into two parts, the inner part stores unfiltered water and the filter element, and the outer large container stores the filtered purified water. This kind of water purifying cup is not only bulky, unsealed, and inconvenient to carry out, but also the water purifying cup uses the gravity of the water itself as the pressure to pass through the filter screen, so when the water is more than half of the water, its filtration rate is significantly reduced. The cost of such water cups with filtering effect on the market is too high and expensive, and it is difficult to promote it among ordinary residents. The water purification device has a narrow range of use and can only be used to filter household tap water.

Fourth, prevent the water in the cup from overflowing during the operation and squeezing, and then put the inner drinking cup 3 and the filter membrane assembly below it into theouter cup 2 for holding water, and therubber ring 11 is an interference fit outside thewater holding cup 2. In thecup 2, the upper and lower parts of the outer water cup are separated by therubber ring 11. The inner drinking cup 3 and the filter membrane assembly below it and theouter cup 2 form a piston assembly. The water flow in the waterouter cup 2, due to the downward pressure of the drinking water inner cup 3, the water flow pressure in the waterouter cup 2 becomes larger. At this time, the ultrafiltration membrane, reverse osmosis membrane, and ultrafiltration membrane take the pressure difference on both sides of the membrane as The driving force is that the ultrafiltration membrane is used as the filter medium. Under a certain pressure, the water first contacts the filter screen and then the filter membrane, and selectively permeates under the filtration action of the membrane, that is, the original solution (outdoor water directly taken) is filtered by The mesh 14 is filtered, and after the activated carbon 15 absorbs the odor and absorbs the macromolecular impurities, when the raw liquid flows through the membrane surface, many tiny pores densely covered on the surface of the ultrafiltration membrane only allow water and small molecular substances to pass through and become permeate. The substances in the original solution whose volume is larger than the pore size of the membrane surface are trapped on the liquid inlet side of the membrane and become concentrated solution, thus realizing the purpose of purifying, separating and concentrating the original solution. The membrane separation operation of separating the solvent from the solution; after the membrane treatment, the water directly enters the drinking water inner cup 3 after being preliminarily purified. At this time, the lid switch 8 is turned on, and the lid switch 8 is connected to theultraviolet lamp 5 and thebattery box 6. The circuit, theultraviolet lamp 5 emits light and the ultraviolet light emitted by theultraviolet lamp 5 is used to photolyse and deform the bacterial protein, and the amino acids, nucleic acids and enzymes of the bacterial body are destroyed; at the same time, the ultraviolet light will ionize the oxygen in the air when it passes through the air. Ozone is generated, which strengthens the sterilization effect; this is a purely physical sterilization method, which has the advantages of simplicity, convenience, no secondary pollution and easy operation; An additional layer of dark paint is added to protect the safety of the user.

所述超滤膜、反渗透膜、活性炭为本实用新型的直接应用，不属于本实用新型的保护范围故省略其具体材质结构和具体工作原理。The ultrafiltration membrane, reverse osmosis membrane, and activated carbon are the direct application of the present invention and do not belong to the protection scope of the present invention, so their specific material structures and specific working principles are omitted.
