具体实施方式

请参阅图1至图5，本申请一实施例提供一种净水机10，包括滤芯组件11和提手12。所述提手12与所述滤芯组件11转动连接。所述提手12上与所述滤芯组件11转动连接的位置为转接点，所述滤芯组件11上与所述提手12转动连接的位置为支撑点。
请一并参阅图6，所述滤芯组件11设有接头112。所述净水机10还包括水路板132。如图8和图9所示，所述水路板132上设有与所述接头112匹配的接口1324。如图1至图5所示，所述滤芯组件11上的接头112能够插入所述接口1324中，使得所述原水能够进入所述滤芯组件11，同时过滤后的纯水能够排出所述滤芯组件11。
进一步地，所述水路板132上设有限位部1321，所述提手12设有锁紧部1221和拆卸部1222。锁紧部1221和拆卸部1222相对且间隔设置。如图1和图3所示，当所述提手12相对于所述滤芯组件11沿第一方向转动时，所述锁紧部1221抵压于所述限位部1321以使所述接头112插入并压紧在所述接口1324中。在一实施例中，所述的沿第一方向转动可以指在如图1和图3所示角度下提手12逆时针转动，图1所示为锁紧部1221刚开始与所述限位部1321接触时的状态，图3所示为接头112完全压紧在所述接口1324中时，所述锁紧部1221完全抵压在所述限位部1321下方时的状态。
如图4和图5所示，当所述提手12相对于所述滤芯组件11沿第二方向转动时，所述拆卸部1222抵压于所述限位部1321以使所述接头112从所述接口1324中拔出。第二方向与第一方向相反。具体地，这里所述的沿第二方向转动可以指在如图4和图5所示角度下提手12顺时针转动。图4为沿第二方向转动时提手12上拆卸部1222与所述限位部1321初始接触时的状态。图5为提手12转动至接头112从所述接口1324中松脱时的状态。
上述方案提供了一种净水机10，所述限位部1321直接设置在所述水路板132上，所述提手12直接设置在所述滤芯组件11上。利用所述提手12与所述限位部1321之间的配合关系能够使所述接头112与所述接口1324直接对位锁紧，或者直接脱离，尽量减少中间尺寸链，降低中间装配误差的可能性，从而降低对各个零件加工降低的要求，降低加工难度。具体地，在装配过程中，先将所述滤芯组件11上的接头112与所述水路板132上的接口1324相对，然后沿第一方向转动所述提手12，使得所述锁紧部1221抵压于所述限位部1321上，直至所述接头112插入并压紧在所述接口1324中。在无其他外力作用的情况下，所述滤芯组件11上的接头112与所述水路板132上的接口1324始终处于连通状态。在需要拆开所述接头112与所述接口1324时，沿第二方向转动所述提手12，使得所述拆卸部1222抵压于所述限位部1321以使所述接头112从所述接口1324中拔出。
在一实施例中，为了使得水路板132承受较高水压，水路板132的强度较高。将所述限位部1321设置在所述水路板132上，可以有效保障拆装过程中整体强度，改善整机的受力情况。
为了保障所述接头112与所述接口1324连接时的密封可靠性，在一个实施例中，如图6所示，所述接头112设有密封圈。当所述接头112插入所述接口1324中时，所述密封圈压紧在所述接头112与所述接口1324的侧壁之间。所述密封圈的设置可阻碍所述接头112与所述接口1324之间发生相对移动，从而使得拆装所需作用力较大。
在一个实施例中，如图7所示，所述提手12设有握持部1211。所述提手12上的握持部1211、转接点和锁紧部1221构成第一省力杠杆。具体地，所述锁紧部1221上与所述限位部1321抵压的面位于所述转接点远离所述握持部1211的一侧。组装过程中，如图1和图3所示，为所述握持部1211施加向下的作用力，借助所述第一省力杠杆，所述限位部1321为所述锁紧部1221提供支撑，所述提手12以所述锁紧部1221上与所述限位部1321抵压的点作为支点转动，所述转接点相对于所述水路板132移动，同步带动与所述提手12连接的滤芯组件11相对于所述水路板132移动，使得所述接头112插入所述接口1324中。利用杠杆省力原理，有效减小所需作用在所述握持部1211上的作用力，使得操作过程更加便利。
可选地，所述锁紧部1221上与所述限位部1321抵压的面也可以位于所述握持部1211与所述转接点之间，只要所述提手12上的握持部1211、转接点和锁紧部1221构成第一省力杠杆即可。例如，所述转转接点位于所述提手12的一端，当所述接头112初步与所述接口1324对准时，可以将所述提手12先调整到锁紧部1221位于所述限位部1321远离所述接头112的一侧，然后为握持部1211施加靠近所述接头112方向上的作用力，随着所述提手12转动，所述限位部1321为所述锁紧部1221提供抵压的作用力，使得所述转接点相对于所述水路板132移动，同步带动与所述提手12连接的滤芯组件11相对于所述水路板132移动，使得所述接头112插入所述接口1324中。
在一实施例中，如图7所示，所述提手12上的握持部1211、转接点和拆卸部1222构成第二省力杠杆。具体地，所述拆卸部1222上与所述限位部1321抵压的面位于所述转接点远离所述握持部1211的一侧。图3为接头112安装在所述接口1324中时的状态，此时所述限位部1321与所述锁紧部1221抵紧。当需要拆卸时，如图4和图5所示，为所述提手12的握持部1211施加向上提起的作用力，借助所述第二省力杠杆，所述拆卸部1222逐渐抵压到所述限位部1321上。所述提手12在沿第二方向转动的过程中，所述限位部1321 为所述拆卸部1222提供支撑，使得所述提手12以所述拆卸部1222上与所述限位部1321抵压的点为支点转动，所述转接点相对于所述水路板132移动，同步带动所述滤芯组件11相对于水路板132移动，使得所述接头112从所述接口1324中拔出。
可选地，所述拆卸部1222上与所述限位部1321抵压的面也可以位于所述转接点与所述握持部1211之间。与前文中所述拆卸部1222上与所述限位部1321抵压的面也可以位于所述握持部1211与所述转接点之间的方案类似。当接头112安装在所述接口1324中时，在所述接口1324的朝向上，所述限位部1321与所述拆卸部1222依次设置，此时为所述握持部1211提供与所述接口1324朝向相反的下压力，所述拆卸部1222抵压在所述限位部1321上，所述转接点沿所述接口1324的朝向上移动，继而使滤芯组件11相对于水路板132沿接口1324朝向移动，从而使得接头112从所述接口1324中拔出。
如图6所示，在一个实施例中，所述滤芯组件11上设有所述接头112的一端为首端，所述支撑点位于所述滤芯组件11的首端，所述接头112悬挂在所述滤芯组件11首端外，所述接头112的出口沿所述滤芯组件11的轴向朝向所述滤芯组件11的尾端。如图8和图9所示，所述接口1324位于所述水路板132的顶面，所述限位部1321位于所述水路板132的顶部。拔插所述接头112的方向即为所述滤芯组件11的轴向。
如图1和图3所示，组装过程中，所述锁紧部1221逐渐抵压于所述限位部1321上靠近所述滤芯组件11尾端的一侧，使得所述接头112插紧在所述接口1324中。如图4和图5所示，拆卸过程中，所述拆卸部1222抵压于所述限位部1321远离所述滤芯组件11尾端的一侧。
如图8和图9所示，在一个实施例中，所述水路板132上设有两个辅助板1325。所述水路板132的正面朝向所述滤芯组件11，所述辅助板1325延伸至所述水路板132的正面，两个辅助板1325分别位于所述水路板132的相对的两侧，所述限位部1321包括位于所述辅助板1325上背离所述滤芯组件11的侧面的凸起。
拆装的过程中所述拆卸部1222和所述锁紧部1221主要位于所述辅助板1325上背离所述滤芯组件11的一侧。所述提手12在转动的过程中，所述拆卸部1222和所述锁紧部1221与所述限位部1321之间位置发生变化，从而实现拆装。
如图3所示，在一个实施例中，所述限位部1321上与所述锁紧部1221抵压的面为第一配合面1322，在靠近所述水路板132的方向上所述第一配合面1322逐渐向靠近所述水路板132顶面的方向延伸。
当所述锁紧部1221与所述第一配合面1322抵压将滤芯组件11锁紧时，如图3所示， 所述第一配合面1322为所述锁紧部1221提供的作用力可以分解为沿所述滤芯组件11轴向的第一分力F1和垂直于所述水路板132的第二分力F2。换言之，所述限位部1321不仅为所述提手12和滤芯组件11提供了将接头112插紧在所述接口1324中第一分力F1，也为所述提手12和滤芯组件11提供了靠紧所述水路板132的第二分力F2，确保所述提手12与所述限位部1321锁紧可靠。
如图8和图9所示，在一个实施例中，所述限位部1321上与所述拆卸部1222抵压的面为第二配合面1323。如图3所示，当所述接头112插入并压紧在所述接口1324中时，所述拆卸部1222与所述第二配合面1323之间间隔设置。换言之，所述提手12沿第二方向转动初期所述拆卸部1222与所述第二配合面1323并未接触，两者之间存在一定虚位，所述限位部1321不会阻碍所述提手12沿第二方向转动。当提手12转动预设角度后，如图4所示，所述拆卸部1222才与所述第二配合面1323接触，继而转接点才开始相对于所述水路板132移动，提升操作手感。
具体地，为了进一步提升操作手感，避免出现阻力忽大忽小的情况，如图3至图5所示，所述拆卸部1222上与所述第二配合面1323抵压的面为弧形凸面。从而在沿第二方向转动所述提手12的过程中，所述第二省力杠杆的阻力臂长度逐渐增大。所述拆卸部1222开始与所述第二配合面1323抵压时，所述接头112与所述接口1324刚开始发生相对移动，所需的作用力较大，动力臂与阻力臂的比值较大，因此省力比例较大。随着所述提手12继续沿第二方向转动，所述接头112与所述接口1324之间挤压的紧密型降低，所需的作用力减小，而动力臂与阻力臂的比值较小，省力比例变小。从而整个过程中用户所需作用在提手12上的力变化较小，提升操作手感。
一个实施例中，如图1所示，所述净水机10还包括支撑壳131，所述支撑壳131围成安装腔，所述滤芯组件11插在所述安装腔中。所述安装腔的朝向与所述接口1324的朝向一致。所述水路板132与所述支撑壳131连接，构成整机壳体组件13。
具体地，组装过程中，如图1所示，先将所述滤芯组件11初步插入到所述安装腔中，所述接头112与所述接口1324对准，然后沿第一方向转动所述提手12，所述锁紧部1221抵压于所述限位部1321，所述提手12上的转接点相对于水路板132移动，而水路板132与所述支撑壳131连接，因此同时所述转接点也相对于支撑壳131移动，进而所述接头112锁紧在所述接口1324中的同时所述滤芯组件11安装锁紧在所述安装腔中。
同理，提手12沿第二方向转动过程中，所述接头112从所述接口1324中拔出的同时，所述滤芯组件11从所述安装腔中抽出一定距离，使得所述滤芯组件11相对于所述水路板 132和支撑壳131松脱。
在一实施例中，如图3至图5所示，所述支撑壳131的外周面设有限位筋，所述限位筋限位于所述辅助板1325靠近所述安装腔底壁的一侧。从而当所述拆卸部1222抵压在所述限位部1321上背离所述安装腔底壁的面上时，所述限位部1321和所述辅助板1325不会向靠近所述安装腔底壁的方向移动，从而为所述拆卸部1222提供反作用力，而将所述滤芯组件11从所述安装腔中拆出，同时使得所述接头112与所述接口1324松脱。
在一个实施例中，如图7所示，所述提手12包括中间握持段121和位于所述中间握持段121两端的连接段122。所述握持部1211位于所述中间握持段121上，两个所述连接段122夹在所述滤芯组件11的两侧，两个所述连接段122上均设有所述转接点，两个所述连接段122均包括所述锁紧部1221和所述拆卸部1222。换言之，所述提手12上包括两个第一省力杠杆和两个第二省力杠杆。所述握持部1211与位于同一连接段122上的转接点和锁紧部1221构成一个第一省力杠杆，所述握持部1211与位于同一连接段122上的转接点和拆卸部1222构成一个第二省力杠杆。所述水路板132上设有两个所述限位部1321，两个限位部1321分别位于所述滤芯组件11的相对的两侧且分别与两个所述连接段122对应。
所述提手12通过两端的连接段122上的转接点与所述滤芯组件11上的支撑点转动连接，组装的过程中所述提手12两端的锁紧部1221同步与两个限位部1321接触，拆卸的过程中所述提手12两端的拆卸部1222同步与两个限位部1321接触。
在一个实施例中，所述限位部1321包括限位凸起，如图7所示，所述锁紧部1221与所述拆卸部1222之间设有让位槽123，如图1和图3所示，当所述提手12沿第一方向转动时所述限位部1321从所述让位槽123的开口逐渐进入所述让位槽123中，直至所述锁紧部1221抵压于所述限位部1321以使所述接头112插入并压紧在所述接口1324中。此时，所述锁紧部1221与所述限位部1321在所述接口1324的朝向上依次设置。当所述提手12沿第二方向转动时，如图4和图5所示，所述限位部1321从所述让位槽123的开口逐渐退出所述让位槽123，所述拆卸部1222逐渐与所述限位部1321抵压直至所述接头112从所述接口1324中拔出。
具体地，如图7所示，所述让位槽123的开口位于所述提手12两端的端面，所述让位槽123贯穿所述提手12的内侧面和外侧面，使得所述锁紧部1221与所述拆卸部1222间隔布置。如图3所示，当所述限位部1321位于所述让位槽123中时，所述拆卸部1222和锁紧部1221分别位于所述限位部1321的上下两侧。这里所述限位部1321的上侧是指远离安装腔底壁的一侧，下侧是指靠近安装腔底壁的一侧。
具体地，如图3所示，所述第二分力F2的方向大致沿与所述让位槽123的开口朝向分布，从而所述锁紧部1221能够阻挡所述限位部1321退出所述让位槽123。
在一个实施例中，如图7所示，所述连接段122为板状结构。所述连接段122还包括连接所述锁紧部1221和所述拆卸部1222的主体部1223。所述主体部1223与所述锁紧部1221和所述拆卸部1222围成所述让位槽123。所述主体部1223与所述中间握持部1211连接，所述主体部1223上与所述中间握持部1211连接的位置相对于所述锁紧部1221更靠近所述拆卸部1222，所述转接点位于所述拆卸部1222上。所述中间握持段121为弧形段，所述拆卸部1222大致位于所述中间握持段121两端的延长线上，而所述主体部1223和所述锁紧部1221组成的悬臂则悬设在所述中间握持段121外。
如图1至图5所示，为板状结构的两个连接段122位于所述滤芯组件11的两侧，分别与所述滤芯组件11转动连接。基于所述主体部1223上与所述中间握持段121连接的位置相对于所述锁紧部1221更靠近所述拆卸部1222，所述转接点位于所述拆卸部1222上。因此，如图1和图3所示，所述锁紧部1221与所述中间握持段121错位布置，所述锁紧部1221与所述主体部1223连接构成的悬臂悬在所述中间握持段121外。在锁紧过程中，所述锁紧部1221与所述限位部1321抵压时，在锁紧部1221与主体部1223连接处应力较大，易出现断裂。进一步地，如图7所示，所述主体部1223与所述锁紧部1221连接处设有加强筋125，提升所述悬臂的强度。
在一个实施例中，如图7所示，还可以将所述主体部1223与所述锁紧部1221连接出的厚度设置为大于所述锁紧部1221上其他部分的厚度，从而增加锁紧部1221与主体部1223连接处受力能力，提升所述悬臂的强度。
在一个实施例中，所述连接段122和所述滤芯组件11两者中其中一者设有转轴124，另一者设有插槽111。例如，如图7所示，所述连接段122上设有转轴124，如图10和图11所示，所述滤芯组件11上设有插槽111。所述转轴124插在所述插槽111中，所述插槽111的侧壁设有凹陷1111，所述转轴124设有止转凸起1241，所述止转凸起1241位于所述凹陷1111中，用于限制所述提手12相对于所述滤芯组件11可转动的角度。
在使用过程中，所述提手12只在允许的一定范围内转动，在此允许转动范围内即可实现接头112与接口1324之间的拆装过程，进一步提高操作的便利性。例如，如图10和图11所示，拆卸过程中，提手12沿第二方向转动到极限位置时，所述止转凸起1241与所述凹陷1111的壁面抵触而无法继续沿沿第二方向转动方向转动，此时所述提手12大致处于沿所述安装腔轴向分布的状态，所述限位凸起已退出所述让位槽123，便于用户作用在 所述中间握持段121上将所述滤芯组件11抽出。
在一个实施例中，如图1至图6所示，所述滤芯组件11设有外壳罩14，当所述滤芯组件11安装到所述安装腔中时所述外壳罩14罩在所述安装腔的开口处。
在一实施例中，如图12所示，所述滤芯组件11的端部设有具有弹性复位能力的弹扣组件15。如图7所示，所述中间握持段121上设有与所述弹扣组件15匹配的卡口1212。如图3所示，当所述锁紧部1221抵压于所述限位部1321使得所述接头112插入并压紧在所述接口1324中时，所述弹扣组件15能够与所述卡口1212配合锁紧。
所述弹扣组件15与所述卡口1212配合锁紧后，所述提手12无法相对于所述滤芯组件11转动，从而所述提手12上的锁紧部1221始终与所述限位部1321抵紧，确保所述接头112始终插紧在所述接口1324中。
在一个实施例中，如图1至图6所示，所述提手12设置在所述滤芯组件11的首端，所述外壳罩14设于所述滤芯组件11首端的端面，所述外壳罩14将所述弹扣组件15盖在所述滤芯组件11上。
如图12所示，在一个实施例中，当所述接头112插紧在所述接口1324中时，所述提手12的中间握持段121刚好转动至贴合在所述滤芯组件11端部的位置。所述弹扣组件15位于所述中间握持段121的内侧，所述卡口1212位于所述中间握持段121上朝向所述弹扣组件15的内侧面上。
在一个实施例中，如图12所示，所述滤芯组件11上设有按钮16，所述按钮16的按压方向沿所述接口1324的轴向。如图13所示，所述按钮16与所述弹扣组件15之间通过一斜面相互抵触，将所述按钮16的按压运动转换为所述弹扣组件15沿所述接口1324径向上的移动，使得所述弹扣组件15脱出所述卡口1212。
当需要将接头112从所述接口1324中抽出时，按压所述按钮16，所述弹扣组件15沿所述接口1324的径向移动退出所述卡口1212，然后沿第二方向转动所述提手12，继而将滤芯组件11取出。
具体地，如图13所示，所述弹扣组件15设有第一斜面1511，所述第一斜面1511相对于所述接口1324的横截面倾斜设置，所述第一斜面1511的法向朝向所述卡口1212。所述按钮16位于所述第一斜面1511朝向所述卡口1212的一侧。当所述按钮16被按压时，所述按钮16给所述第一斜面1511施加与所述接口1324朝向方向相反的作用力，从而使得所述弹扣组件15向退出所述卡口1212的方向移动。
所述外壳罩14上设有第一穿孔和第二穿孔，当所述外壳罩14盖在所述滤芯组件11 上时，所述按钮16能够通过所述第一穿孔暴露在所述外壳罩14外，使得用户能够按压到所述按钮16，所述弹扣组件15能够穿过所述第二穿孔插入所述卡口1212中。
在一个实施例中，如图13所示，所述弹扣组件15包括第一滑块151和弹性复位件152。如图12所示，所述第一滑块151相对于所述滤芯组件11滑动设置，且滑动方向平行于所述滤芯组件11的横截面。所述弹性复位件152位于所述第一滑块151与所述滤芯组件11之间，用于为所述第一滑块151提供向靠近所述卡口1212的方向滑动的复位力。具体地，所述弹性复位件152可以为压缩弹簧，所述压缩弹簧的轴线平行于所述滤芯组件11的横截面。
在另一个实施例中，如图14所示，所述滤芯组件11的端部设有滑扣17，所述中间握持段121上设有与所述滑扣17匹配的插口，当所述锁紧部1221抵压于所述限位部1321使得所述接头112插入并压紧在所述接口1324中时，所述滑扣17能够滑动插入所述插口中。
当提手12沿第一方向转动至接头112插紧在所述接口1324中时，所述插口与所述滑扣17相对，手动推移所述滑扣17使得所述滑扣17插入所述插口中，从而所述提手12相对于所述滤芯组件11无法转动，使得所述接头112可靠配合在所述接口1324中。
在一个实施例中，所述滑扣17和所述中间握持部1211两者中其中一者设有卡扣171，另一者设有与所述卡扣171配合的配合件，当所述滑扣17划入所述插口中时，所述卡扣171与所述配合件卡扣171连接。
在一实施例中，如图15所示，所述滑扣17上设有所述卡扣171。所述中间握持部1211上设有配合件。当手动将所述滑扣17推移至插入所述插口中时，所述卡扣171与所述配合件配合。在不主动解除所述卡扣171与所述配合件的配合状态的情况下，所述滑扣17无法退出所述插口，则所述提手12无法相对于所述滤芯组件11转动。
