图2为本发明可反冲洗的户外净水器反冲洗方法的使用结构示意图；
图3-4，为单根超滤芯膜丝的结构示意图。。
其中，1、第一壳体；11、出水嘴；12、第一内螺纹；2、第二壳体；21、外螺纹；22、出水口；23、入水口；3、接头；31、第二内螺纹；32、第三内螺纹；33、第三壳体；34、入水嘴；4、膜壳；5、膜丝；6、外部消毒液瓶。
具体实施方式
下面，结合附图以及具体实施方式，对本发明做进一步描述：
如图1所示，可反冲洗的户外净水器，包括第一壳体1、第二壳体2和筒状的接头3；第二壳体2内部中空且两端分别具有出水口22和入水口23，该第二壳体2内填充有超滤芯，超滤芯采用过滤精度为0.01--0.05微米的血液透析膜材料，其过滤精度是普通户外净水器的十倍以上；该入水口23以可拆卸的方式固定连接接头3，该出水口22通过一连接结构以可拆卸的方式与第一壳体1一端固定连接，第一壳体1可填充如碳纤维滤芯等的过滤物质；将外部水瓶安装在接头3上时，用力挤压外部水瓶，使外部水从入水口23进入第二壳体2，经过超滤芯的吸附后从出水口22流出，得到可饮用的水；该连接结构还用于反冲洗超滤芯时将出水口22与接头3以可拆卸的方式对接，第一壳体1另一端向外凸出有一出水嘴11，如图2所示，将第一壳体1和接头3从第二壳体2上拆下，并将接头3安装于第二壳体2的出水口22一端，同时 把消毒液瓶安装于接头3上，用力挤压外部消毒液瓶6，使消毒液从出水口22进入第二壳体2，冲刷及溶解超滤芯上的附着物，实现本可反冲洗的户外净水器的反冲洗。
在本实施例中，第二壳体2两端分别设有外螺纹21，且两外螺纹21的形状大小相同；该连接结构为第二壳体2设有出水口22一端的所述外螺纹21；；第一壳体1的一端设有与外螺纹21匹配的第一内螺纹12；接头3一端设有与外螺纹21匹配的第二内螺纹31，通过螺纹连接，使第一壳体1和接头3拆装方便。
为了方便直接饮用而不需使用其他容器来盛装过滤得到的水，出水嘴11呈圆筒状，且出水嘴11口径小于出水口22口径。
一般外部水瓶和消毒液都是使用矿泉水瓶，该本实施例中，接头3包括第三壳体33和入水嘴34，第二内螺纹31设置于第三壳体33一端，第三壳体33另一端设置有与外部水瓶螺纹匹配的第三内螺纹32，入水嘴34固定于第三壳体33内，该入水嘴34呈圆筒状且口径小于外部水瓶口径；外部矿泉水瓶直接和接头3螺纹联接，防止外部水从接头3进入第二壳体2时从接头3中流出，入水嘴34直接插进外部水瓶瓶口内。
采用本实施例中上述可反冲洗的户外净水器的反冲洗方法，包括如下步骤：
S1.将第一壳体1和接头3从第二壳体2上拆下；
S2.将接头3安装在第二壳体2的出水口22，把外部消毒液瓶6装在接头3上，挤压外部消毒液瓶6使消毒液从第二壳体2的出水口22流向入水口23，实现对超滤芯的反冲洗。
本实施例中，超滤芯包括多根如图3-4所示的膜丝5，超滤芯安装于第二 壳体2内时，将膜丝5的开口方向与出水口22方向保持一致，过滤外部水时，如图3所示，箭头表示水流方向，外部水从入水口23流进第二壳体2，此时，膜丝5外壁吸附外部水中的铁锈、污泥、细微杂质、胶体、有机物等杂质；而长期的过滤，外部水中的杂质附着在膜丝5外壁上，导致膜丝5变黄且通水量降低；在S1和S2步骤中，如图2所示，接头3安装于出水口22一端，将装有食用级白醋或食用级消毒液的外部消毒液瓶6安装于接头3上，如图4所示，箭头表示水流方向，挤压外部消毒瓶6使外部消毒液从第二壳体2的出水口22流向膜丝5的U型开口内，并从膜丝5的外壁流出，水压冲刷掉粘附在膜丝5上部分的杂质，消毒液的酸性溶解吸附在超滤芯上的微生物等物质，并同时对超滤芯进行消毒，实现了对超滤芯的反冲洗。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本发明权利要求的保护范围之内。
