请参照图1和图2，在本发明一种实施方式中，该水龙头包括水道4、进水管13和出水管1；所述水道4内设置有阀芯腔、进水通道42和出水通道41，所述进水通道42和所述出水通道41均与所述阀芯腔相通；所述进水管13与所述进水通道42连接，所述出水管1与所述出水通道41连接；所述水道4的外表面设置有包胶层。
本发明提出的水龙头采用包胶设计的原理，将水龙头本体外壳5与涉水的水道4进行材质分隔设计，以保证水道4可采用无铅材料。先通过注塑、压铸或切削成型的方法制造出水道4，再将加工成型好的水道4放置于水龙头本体外壳5模腔中，通过二次注塑的方式，在水道4的外面进行包胶，形成包胶层，即水龙头本体外壳5。由于水道4、进水管13、出水管1、阀芯9均为无铅材料，水龙头进水管13的出水端与水道4进水口连接，阀芯9分别与水道4的进水通道42和出水通道41连接，出水管1的进水口与水道4的出水通道41连接，这样水龙头的进水管13、水道4、阀芯9、出水管1就形成了一个内部畅通的无铅水道4。当水龙头进水管13和净水器连接时，经过滤芯处理的净化水经过无铅水道4，不会有铅及其他重金属析出，真正达到国家水龙头无铅化标准的要求，保证消费者用水安全。

具体地，用铜/合金管做出水管1和/或进水管13的外层，用无铅软管做出水管1和/或进水管13的内层，水从软管中经过就不会向水中引入铅。另外，出水管1和/或进水管13的外层外表面可进行电镀或喷涂处理，从而提高出水管1和/或进水管13的硬度和耐腐蚀等性能，而且也能使出水管1和/或进水管13的外观更加多样化。
请再次参照图1和图2，该实施例中水龙头为双出水无铅水龙头。以下具体说明本体外壳5、水道4、进水管13和出水管1等部件的连接关系。
将出水管1插入水道4上端孔中，即将出水管1的进水口与水道4的出水通道41连通。通过本体装饰盖3将出水管1固定在水道4中，出水管1上设有止卡与本体装饰盖3固定，所述本体装饰盖3与水道4外壁通过螺纹连接固定，出水管1上设有双O密封圈与水道4内壁起密封作用。水道4上端与水龙头本体外壳5连接，左右分别与左阀芯9、右阀芯9连接，底部与水龙头进水管13连接。水龙头本体外壳5既是外观件又是结构件，水道4上端由下往上插入水龙头本体外壳5之中，水道4上设置有凸台43与水龙头本体外壳5上端的凸肩51连接限位；水龙头本体外壳5下端与第二锁紧螺母连接固定。水龙头本体左右端分别与左把手座8、右把手座8相连接。右把手杆7插入右把手座8与右阀芯转轴座10相连接；右阀芯转轴座10分别与右阀芯9、阀芯外壳11、把手杆7和把手座8相连接；阀芯外壳11里面包裹住阀芯9，外面与第一锁紧螺母6相连接，第一锁紧螺母6与水龙头本体外壳5通过螺纹连接对阀芯9进行锁紧固定；水龙头阀芯9外面被阀芯外壳11包裹保护，左端与水道4右侧进水通道42的出水口连接形成封闭水路；阀芯9右侧与阀芯转轴座10相连接。进水管13上端与水道4连接形成密封水路，下端分别与第二锁紧螺母、法兰、锁紧垫片连接固定，密封圈与所述进水管13和水道4进水通道42的进水口连接起密封作用。双出水无铅水龙头是左右对称结构，左边各部件连接方式与右边相同，在此不做赘述。
本发明的技术方案也适用于单出水无铅水龙头。单出水无铅水龙头与双出水无铅水龙头的技术方案一样，区别在于双出水无铅水龙头有两个水道4，可以分别放出两种不同的水。单出水无铅水龙头只有一个水道4。
以下具体说明水龙头的制造方法，该水龙头的制造方法包括：
步骤一、通过注塑、压铸或切削成型的方法制得水道4；
步骤二、将所述水道4置于水龙头本体外壳5的模腔中，通过二次注塑的方法在水道4的外表面进行包胶，形成水龙头本体外壳5，水龙头本体外壳5即为包胶层。
优选地，所述水龙头制造方法还包括：
对所述水龙头本体外壳5的外表面进行电镀形成电镀层。
优选地，所述水龙头制造方法还包括：
对所述水龙头本体外壳5的外表面进行喷涂形成喷涂层。
本发明还提出一种净水机，所述净水机包括如上述任一实施方式所述的水龙头。该水龙头的具体结构参照上述实施例，由于本净水机采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施方式，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
