具体实施方式
下面详细描述本实用新型的实施例，所述实施例的示例在附图中示出，其中自始至 终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本实用新型，而不能理解为对本实用新型的限制。
在本实用新型的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实用新型的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本实用新型的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本实用新型中的具体含义。
在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度小于第二特征。
下面参考图1-图8描述根据本实用新型实施例的用于净水器的水路部件100。其中，水路部件100可以为逆止阀(例如单向阀)、电磁阀、高压开关或增压泵等，但不限于此。在本申请下面的描述中，以水路部件100为电磁阀为例进行说明。
如图1和图2所示，根据本实用新型第一方面实施例的用于净水器的水路部件100例如电磁阀，包括连接头1和密封件2。
例如，可在净水器中设置水路板(图未示出)，并在水路板上设置与水路部件100上的连接头1对应的连接口例如水孔，水路部件100上的连接头1与水路板上连接口配合可将水路部件100例如电磁阀连接在水路板上。由此，可省去传统的水路系统中的PE管、管接头等部件，使得净水器的结构更加紧凑，显著减小了净水器的整机厚度， 节省了厨房等家用空间。
其中，连接头1为外周壁呈阶梯状的空心管，连接头1的外周壁形成有沿连接头的轴向延伸的安装段13和防退段11，防退段11位于连接头1的自由端(例如，图1中的下端)，且防退段11的一端(例如，图1中的上端)与安装段13连接，防退段11的外径小于安装段12的外径。例如，参照图1和图3，安装段13和防退段11的横向截面可以形成为圆形，但不限于此。
密封件2可移动地套设在连接头1的外周壁上，密封件2具有弹性，密封件2在自由状态下的内径等于或小于防退段11的外径。例如，水路部件100正常工作装配时，水路部件100安装在水路板对应的连接口例如水孔内，密封件2套设在安装段13的外周壁上(如图1和图2所示)。由此，在将水路部件100连接在水路板上时，密封件2可起到密封作用，有效地防止漏水。可选地，密封件2可以为O型密封圈例如单O密封圈，密封性好且成本低。
在水路部件100因为售后维修或者进行产线返工、并需要将水路部件100拔出水路板时，也就是说需要将连接头1拔出连接口时，由于密封件2与连接口的内壁之间存在密封件2紧配压缩量，在拔出连接头1的过程中，密封件2将被推向防退段11，并滑入防退段11内，套设在防退段11的外周壁上。
由于安装段13的外径大于防退段11的外径，当密封件2进入防退段11后，密封件2恢复至趋于自然不被压缩但仍与防退段11保持紧配的状态，密封件2的外径减小，使得密封件2与连接口例如水路板上的连接口的内壁之间的压缩量减少。此时密封件2与防退段11外壁之间的摩擦力大于密封件2与连接口的内壁之间摩擦力，从而使得密封件2停留在防退段11内不被连接口带出。由此，可以防止密封件2从连接头1上滑落并进入连接口内，从而省去了将滑落至连接口内的密封件2取出的工序，有效地降低了工作量，减小了维修时间，缩短了返修货售后周期，提高了维修效率。
根据本实用新型实施例的用于净水器的水路部件100，通过在连接头1上设置防退段11，在拔出水路部件100时，可防止密封件2掉入连接口内，从而有效地减小了工作量，减小了维修时间，缩短了返修货售后周期，提高了维修效率。
根据本实用新型的一些实施例，防退段11贯穿连接头1的自由端的端面。参照图1-图4，防退段11的自由端延伸至连接头1的自由端的端面，工艺简单，便于实现。
根据本实用新型的另一些实施例，参照图5-图8，连接头1的自由端的端部设有止挡筋12。具体地，参照图5，止挡筋12可以形成为沿连接头1的周向延伸的环形筋。其中，止挡筋12的外径大于防退段11的外径，由此，可通过止挡筋12对密封件2进行限位，从而可以进一步地防止密封件2从连接头1上脱落。
可选地，止挡筋12可以包括沿连接头1的周向间隔设置的多个子止挡筋，由此，可以减少材料，降低成本，且同样可以起到很好的止挡效果。
根据本实用新型的一些实施例，止挡筋12与连接头1一体成型。由此，可简化加工工艺，降低加工成本。
具体地，参照图7a，沿连接头1的轴向朝向远离连接头1中心的方向上，止挡筋12的自由端(例如，图7a中的下端)的外周面与连接头1的中心轴线之间的距离逐渐减小。由此，便于连接头1快速、准确地伸入连接口中，从而可将水路部件100快速装配至水路板上，节省了装配时间，提高了装配效率。
进一步地，连接头1上设有限位部3，参照图7和图8，限位部3的下端与安装段13的上端相连，且限位部3的外周壁与连接头1的中心轴线之间的距离大于安装段13的外周壁与连接头1的中心轴线之间的距离。例如，在图7和图8的示例中，限位部3的外径大于安装段13的外径。由此，在连接头1与连接口配合时，可防止密封件2滑出连接口、使密封件2与连接口脱离配合，从而可以使得密封件2的位置稳定，提高密封效果。
可选地，参照图6和图8，限位部3与安装段13之间圆滑过渡。由此，可在注塑工艺上实现密封件2的工作位置处无夹线，从而极大地保证了密封件2的密封性和可靠性。
下面参考图1-图8描述根据本实用新型实施例的用于净水器的水路部件100的两个具体实施例。
实施例一：
如图1-图4所示，根据本实用新型实施例的用于净水器的水路部件100例如电磁阀，包括连接头1和密封件2。其中，水路部件100上的连接头1可与水路板上连接口配合以将水路部件100例如电磁阀连接在水路板上。
其中，连接头1为外周壁呈阶梯状的空心管，连接头1的外周壁形成有沿连接头的轴向延伸的安装段13和防退段11，防退段11位于连接头1的自由端，且防退段11的上端与安装段13连接，防退段11的外径小于安装段12的外径。
密封件2可移动地套设在连接头1的外周壁上，密封件2具有弹性，密封件2在自由状态下的内径等于或小于防退段11的外径。
水路部件100正常工作装配时，水路部件100安装在水路板对应的连接口例如水孔内，密封件2密封件2套设在安装段13的外周壁上。由此，在将水路部件100连接在水路板上时，密封件2可起到密封作用，有效地防止漏水。
在售后维修或者进行产线返工、并需要将水路部件100拔出水路板时，也就是说需 要将连接头1拔出连接口时，由于密封件2与连接口的内壁之间存在密封件2紧配压缩量，在拔出连接头1的过程中，密封件2将被推向防退段11，并滑入防退段11内。由此，可以防止密封件2从连接头1上滑落并进入连接口内，从而省去了将滑落至连接口内的密封件2取出的工序，有效地降低了工作量，减小了维修时间，缩短了返修货售后周期，提高了维修效率。
具体地，防退段11贯穿连接头1的自由端的端面。参照图2和图4，防退段11的自由端延伸至连接头1的自由端的端面，工艺简单，便于实现。
进一步地，连接头1上设有限位部3，参照图3和图4，限位部3与安装段13的上端相连，且限位部3的外周壁与连接头1的中心轴线之间的距离大于安装段13的外周壁与连接头1的中心轴线之间的距离。例如，在图3和图4的示例中，限位部3的外径大于安装段13的外径。由此，在连接头1与连接口配合时，可防止密封件2滑出连接口、使密封件2与连接口脱离配合，从而可以使得密封件2的位置稳定，提高密封效果。
参照图2和图4，限位部3与安装段13之间圆滑过渡。由此，可在注塑工艺上实现密封件2的工作位置(如图1所示)处无夹线，从而极大地保证了密封件2的密封性和可靠性。
实施例二：
如图5-图8所示，本实施例中的用于净水器的水路部件100与实施例一中的用于净水器的水路部件100的结构大体相同，其中相同部件采用相同的标号，不同之处仅在于，实施例一中的防退段11贯穿连接头1的自由端，而本实施例中的连接头1的自由端的端部设有止挡筋12。
具体地，参照图5，止挡筋12形成为沿连接头1的周向延伸的环形筋。其中，止挡筋12的外径大于防退段11的外径，由此，可通过止挡筋12对密封件2进行限位，从而可以进一步地防止密封件2从连接头1上脱落。
其中，止挡筋12可以包括沿连接头1的周向间隔设置的多个子止挡筋，由此，可以减少材料，降低成本，且同样可以起到很好的止挡效果。
具体地，止挡筋12与连接头1一体成型。由此，可简化加工工艺，降低加工成本。
参照图5-图8，沿连接头1的轴向朝向远离连接头1中心的方向上，止挡筋12的自由端的外周面与连接头1的中心轴线之间的距离逐渐减小。由此，便于连接头1快速、准确地伸入连接口中，从而可将水路部件100快速装配至水路板上，节省了装配时间，提高了装配效率。
根据本实用新型实施例的用于净水器的水路部件100，可防止密封件2掉入连接口 内，从而有效地减小了工作量，减小了维修时间，缩短了返修货售后周期，提高了维修效率。
根据本实用新型第二方面实施例的净水器，包括根据本实用新型上述第一方面实施例的水路部件100。
根据本实用新型第二方面实施例的净水器，通过设置根据本实用新型上述第一方面实施例的水路部件100，减小了维修时间，缩短了返修货售后周期，提高了维修效率。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本实用新型的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本实用新型的实施例，本领域的普通技术人员可以理解：在不脱离本实用新型的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本实用新型的范围由权利要求及其等同物限定。
