具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。例如，尽管本申请是结合洗衣机的吸水泵来描述的，但是，本发明的技术方案并不局限于此，该管接头显然也可以应用于其他类似的场合，这种改变并不偏离本发明的原理和范围。
需要说明的是，在本发明的描述中，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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发明的限制。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。
此外，还需要说明的是，在本发明的描述中，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。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1所示，该图示出了本发明的管接头的第一实施例。该管接头包括主体部分1以及设置在主体部分1上的密封圈11和定位筋12，定位筋12的外径小于密封圈11的未压缩状态下的外径并且大于主体部分1的外径。当该管接头与其他部件－例如吸水泵的管道接合时，密封圈11被压缩并因此产生密封作用，定位筋12在密封圈11之外形成第二个支撑点，使本发明的管接头被更稳固地支撑在其他部件－例如吸水泵的管道中。换句话说，通过在管接头的主体部分1上设置定位筋12，与密封圈11一起形成双点支撑或双线支撑，实现了对管接头的有效定位，防止管接头相对吸水泵晃动，装配紧密，保证吸水泵能够正常使用，因此改善了用户的使用体验。关于此点，需要指出的是，上述“双点支撑”和“双线支撑”含义是相同的，都是指密封圈11和定位筋12分别支撑一个位置，按照图1的方位，左侧和右侧分别有两个支撑点，但是，密封圈11和定位筋12实际上是周向延伸的，它们与吸水泵的管道之间是线接触，所以称为“双线支撑”。
如图1所示，主体部分1的外壁上设有与密封圈11相适配的凹槽13以固定密封圈11，能够更加方便、快捷地将密封圈11固定在主体部分1上。在图1的实施例中，密封圈11的数量为一个，密封圈11位于定位筋12的上方，密封圈11与定位筋12配合使用。但是，如下文将更详细描述的，密封圈11的数量并不局限于一个。
如图1所示，定位筋12为环绕主体部分1的周向凸缘，这个使得管接头在组装状态下能够被有效固定或支撑。优选地，定位筋12的外径小于密封圈11的未压缩状态下的外径。并且，定位筋12的外径大于所述主体部分1的外径，具有外径差H，H随吸水泵的进水口的口径、主体部分1的外径、密封圈11的外径的变化而变化。通过定位筋12与密封圈11的双点支撑对管接头进行有效定位，防止管接头相对吸水泵晃动，装配紧密。
下面参阅图2，在一个替代方案中，为了提高定位筋12定位的稳定性，定位筋12与用于固定密封圈11的凹槽13相连，即，定位筋12的侧面构成凹槽13的一个侧壁(图2中的下侧壁)，扩大了定位筋12的有效作用面积，保证了定位的稳定性，保证吸水泵能够正常使用，因此改善了用户的使用体验。
为了防止对吸水泵造成损伤，定位筋12上设置有圆弧倒角结构，相对于非倒角结构而言，避免了对采用塑料材质制备的吸水泵的进水口的内壁造成损伤，延长了吸水泵的使用寿命。
此外，定位筋12与主体部分1优选地一体成型，采用一体成型的结构便于模具的设计制作。
下面参阅图3，该图示出了本发明的管接头的第二实施例。在该实施例中，密封圈11的数量为两个，两个密封圈11沿主体部分1的轴线方向连续设置或间隔设置，两个密封圈11将密封结构由单线密封接触优化为双线密封接触，配合更紧密，而且起到了双重密封的效果，可靠性更高，有效解决了吸水泵漏气、密封性能差的问题，避免了因一个密封圈11失效而导致漏气的现象，因此改善了用户的使用体验。
下面参阅图4，该图示出了本发明的管接头的第三实施例。为了加强密封效果，在主体部分1上设置定位筋12和两个密封圈11，定位筋12位于两个密封圈11之间，形成了三线支撑和双线密封，实现了对管接头的有效定位和多重密封。
优选地，定位筋12的两侧分别和与其相邻的用于固定密封圈11的凹槽13相连，定位筋12的两个侧面分别构成两个凹槽13的一个侧壁，扩大了定位筋12的有效作用面积，提高了定位的稳定性以及密封的可靠性。
优选地，两个相邻的密封圈11之间的定位筋12沿主体部分1的轴线方向形成为弧形或平直的，分别如图5和图6所示。
本领域技术人员能够理解的是，在上述主体部分1上设置的密封圈11的数量不限于两个，可以根据实际情况改变其数量，但是无论密封圈11的数量增加多少，将所有的密封圈11沿主体部分1的轴线方向连续设置或间隔设置，每两个相邻的密封圈11之间可均设有一个定位筋12，充分保证了定位的稳定性和密封的可靠性。
如图1、图2和图3所示，在一种较佳的实施方式中，主体部分1包括第一连接头14和第二连接头15，第一连接头14和第二连接头15通过连接管2连接，第一连接头14上设有定位筋12和密封圈11，第二连接头15上设有连接螺纹。
其中，连接管2与第一连接头14的连接端设有起定位作用的第一挡圈21，连接管2与第二连接头15的连接端设有起定位作用的第二挡圈22，第一挡圈21和第二挡圈22均一体设于连接管2上。第一挡圈21的外径大于第一连接头14的外径，第二挡圈22的外径大于第二连接头15的外径，当第一连接头14与吸水泵的进水口连接，以及第二连接头15与水管连接时，分别能够起到止挡定位的作用。
此外，连接管2的侧壁上设有与吸水泵卡紧连接的卡紧件23，卡紧件23能够将第一连接头14与吸水泵卡锁连接。第一挡圈21上设有便于将第一连接头14和吸水泵分离的开口211。当需要将第一连接头14与吸水泵拆卸时，按着卡紧件23的下端，如图1所示，使得卡紧件23与吸水泵的进水口处于不连接的状态，人手的大拇指从开口211处抠住吸水泵的进水口，将其从第一连接头14上拔下来，无需辅助工具，便于拆卸。
为了防止外力作用于开口211处将第一连接头14与吸水泵分开，开口211设置在第一挡圈21朝向卡紧件23的部位，通过卡紧件23对开口211进行防护，避免了外力直接作用在开口211处将第一连接头14与吸水泵分开。如上所述，当需要将第一连接头14与吸水泵拆卸时，按着卡紧件23的下端，使卡紧件23与吸水泵的进水口处于不连接的状态，人手 的大拇指伸入卡紧件23与第一连接头14之间的间隙，并从开口211处抠住吸水泵的进水口，将其从第一连接头14上拔下来，防止了因外力将吸水泵与第一连接头14分离。在附图所示的实施例中，连接管2为L形，但是，本发明显然可以采用任何适当的连接管形状。
除了上述管接头外，本发明还提供了一种洗衣机，该洗衣机包括上述管接头，通过上述管接头使得进水管能够与吸水泵稳定地密封连接，避免产生漏气的现象，保证吸水泵能够正常使用，提高用户满意度。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
