具体实施方式
洗衣机的水龙头是多个厂家各自独立设计，进水管与水龙头之间可能存在一定的公差，使得进水管与水龙头连接后产生一定的缝隙，造成进水管和水龙头密封性不好，进水管与水龙头连接处产生漏水、冒水等问题。有的用户在水龙头上缠绕生料带(即四氟乙烯带)阻止连接处漏水，漏水问题依旧存在。
如图1-图7所示，本实施方式提供了一种洗衣机进水管的连接装置，该连接装置包括出水头1和进水管2，其中出水头1安装在水龙头3的出水端，进水管2的第一端与出水头1连接，第二端与洗衣机的进水口连接。
出水头1的内部安装有可上下移动的密封堵头11，密封堵头11的最大外径小于出水头1的内壁直径，以便与出水头1的内壁间形成出水流道。密封堵头11靠近出水口15一端的直径与出水头1的出水口15的直径相同，使得密封堵头11可以封闭出水头1的出水口15。
可选地，密封堵头11远离出水口15的一端连接有压缩弹簧12。在出水头1未连接进水管2情况下，压缩弹簧12靠自身弹力将密封堵头11压紧在出水口15上。进水管2的第一端内设置有顶柱211，当进水管2套接至出水头1外部时，顶柱211向远离出水口15的方向上顶起密封堵头11，密封堵头11压紧压缩弹簧12，顶柱211与出水头1内壁间形成流道，使得进水管2与出水头1相连通(图中箭头所指方向即为水流方向)。
可选，进水管2的第一端固定有快速接头21，并通过快速接头21与出水头1连接。可选地，出水头1的外部设有凹槽14，快速接头21的外部设有可沿密封堵头11的运动方向滑动的锁套214，锁套214内安装有自锁弹簧212和滚珠213，滚珠213在自锁弹簧212的推动下可卡入凹槽14内，使快速接头21与出水头1相锁紧。
向下按压锁套214，将出水头1插入快速接头21内，松开锁套214，锁套214在自锁弹簧212弹性力的作用下向远离出水口15的方向运动复位。锁套214上的自锁倒角结构将滚珠213挤压嵌入凹槽14内，并发出“啪”的声音，表明快速接头21与出水头1已锁紧连接，进水管2不会脱落。
向下施加外力推动快速接头21，快速接头21上的解锁倒角结构将滚珠213挤压并逐渐向远离出水头1外壁的方向运动。滚珠213离开凹槽14，并进入锁 套214的解锁凹槽中，拔出下进水管2。在至少一种实施方式中，进水管2与出水头1之间可以采用螺纹连接。
可选地，出水头1的出水端与快速接头21相抵接的位置还设有环形密封垫22，以避免出水头1与进水管2连接漏水。出水头1的出水端外部还设置有圆角，防止出水头和进水管连接时损伤进水管2。
顶柱211固定在快速接头21内，其中顶柱211可以是单个部件，采用卡扣或螺栓固定件固定在快速接头21中。顶柱211与快速接头21可以采用塑料材料通过一体注塑成型方法制成。一体注塑成型方法制作方便、成本低，进水管2的密封性好。
可选的，进水管2的第二端还固定有螺母套23，用于旋拧在洗衣机进水阀的接头上，确保进水管2与洗衣机进水阀的接头紧固连接，防止二者的连接处出现漏水。在至少一种实施方式中，快速接头21和螺母套23均为塑料件，而位于快速接头21与螺母套23之间的连接管为橡塑材质的软管，其中快速接头21、螺母套23分别通过卡箍与连接管进行紧固连接。
在至少一种实施方式中，水龙头3包括本体31、止挡32、连接部33、阀芯帽34和把手35，其中本体31是水龙头3的主体部分，是其他零部件的组装骨架。图1中，本体31的下端，即水龙头3的出水端设有外螺纹，出水头1的进水端设有内螺纹，出水头1与水龙头3通过螺纹固定连接。
可选的，本体31与出水头1连接处还设置有密封垫片14，以确保本体31与出水头1的连接处具有良好的密封性。连接部33位于本体31的进水端，连接部33上可以设有外螺纹，用于与家庭送水管连接。
本体31的内部安装有阀体37，阀体37内可转动地安装有阀芯36。阀芯帽34的底部设有连接件341，连接件341与阀芯36卡接，并能带动阀芯36转动。阀芯帽34的外部还连接有把手35，方便调节阀芯36，控制水流的通断及水流大小。至少一种实施方式中，采用一字型把手35，且把手35与阀芯帽34为一体成型制作。
可选地，如图4和图6所示，阀体37与本体31之间设有两道密封圈，使得阀体37安装在本体31后，确保阀体37与本体31之间良好的密封性。阀芯36与阀体37之间也可以设有三道密封圈，以确保阀芯36与阀体37连接处的密封性。
可选地，如图4所示，阀芯36的下端连接有第二陶瓷片39，第二陶瓷片39的下方设有第一陶瓷片38，第二陶瓷片39和第一陶瓷片38上均开设有通水孔。当旋转阀芯36的时候，阀芯36的下端带动第二陶瓷片39转动，使得第二陶瓷片39上的通水孔对准第一陶瓷片38上的通水孔，使阀体37两端的流道相连通。
水流进入水龙头3的连接部33，并达到阀体进水口371，分别经过第一陶瓷片38和第二陶瓷片39上的通水孔进入阀体37内，通过阀体出水口372，达到出水头1，经过密封堵头11与出水头内壁的间隙流道，进入进水管2。陶瓷片耐老化、耐磨损，延长水龙头3的使用寿命。
利用出水头实现水龙头与进水管的快速连接，在出水头内设置密封堵头，防止了进水管滑落时水龙头出现漏水。密封堵头远离出水口的一端连接压缩弹簧，当进水管脱落时，压缩弹簧依靠自身弹力将密封堵头压紧在出水头的出水口。
进水管内设有顶柱，当进水管套接至出水头外部时，顶柱向远离出水口15的方向顶起密封堵头，使进水管与出水流道连通，该顶柱的设计简化了进水管的结构，可以让密封堵头完全处于出水头内部，保护了密封堵头。
工业实用性
洗衣机进水管的连接装置采用出水头实现进水管与水龙头的密封连接，减少了洗衣机的进水管与水龙头连接不匹配，密封性差，连接处容易漏水、进水管崩开或脱落等问题，提升了用户体验。
